Jonsered is a brand that does not necessarily get the recognition it deserves as it is relatively unknown compared to the likes of Stihl and Husqvarna. In our opinion, the manufacturer is responsible for introducing the first ever single manned chainsaw. This acted as the blueprint for all future best chainsaws, and even to this very day, chainsaws are modelled on Jonsered’s original prototype.

How Good are Jonsered Chainsaws?

We have found Jonsered chainsaws to always be both powerful and reliable. However, there will always be those people who say otherwise due to their own negative personal experiences with their chainsaws. The number of complaints and returns Jonsered receive is actually very little. This alone speaks absolute volumes in regards to the quality of their chainsaws.

Why buy a Jonsered Chainsaw?

One of the main selling points with this brand is that their chainsaws are actually made by fellow Swedish power tool manufacturer Husqvarna. For those not in the know, Husqvarna are a, if not the, leading chainsaw maker in the world. Therefore, a high level of quality is pretty much guaranteed with their chainsaws.

So we have established they have a strong reputation and produce quality power tools, but how do they measure up in terms of being good value for money? After all, for many this is the main thing that will determine whether or not to buy a Jonsered chainsaw.

On the whole Jonsered chainsaws are generally cheaper than Husqvarna ones, despite them both using many of the same parts, components, and manufacturing processes. We will now take a look at some of Jonsered’s top chainsaw models that are currently available and detail their specifications along with some pros and cons of each.

Jonsered 2240 Chainsaw Review

This particular model causes some debate in the chainsaw world with a lot of people finding it difficult to get started. However, this simply comes from them not reading the chainsaw’s instruction manual correctly, or at all. It comes with a small but reasonably powerful gas motor that is 40 cc. It is the ideal chainsaw for occasional use around the garden. Although it can cut up all the firewood you would ever need, it does not have the power required to cut through thick tree trunks.

A handy feature of the 2240 is the snap locked cylinder covers that are quick release. Because of this the spark plugs and air filter can both be easily accessed for when they need replacing or for maintenance reasons. However, the air filter on the 2240 has been specially designed so that it does not get clogged up with dust and debris as quickly as others do so the need for maintenance is kept to a minimum.

Specifications

• 2.5 horse power
• A 40 cc motor
• A cylinder displacement of 2.5 cubic inch
• An 18 inch bar length
• Tool free chain tensioning
• A total weight of 9.5 pounds

Pros

• Air filter keeps itself clean
• Makes light work of branched and small logs

Cons

• Can be difficult to start

Jonsered 2245 Chainsaw Review

This particular model comes highly recommended by experienced professional arborists. As well as being suitable for professionals, it is also suitable for non-professionals looking for a bit of extra power when cutting up fire wood. It comes armed with a powerful gas motor that is 45 cc. It can handle all the same things as the 2240, but just does them with greater ease, especially on those more stubborn pieces of wood. Even with all the power it possesses the 2245 runs incredibly smooth.

The chainsaw very rarely, if ever, stalls and has a strong idle that rarely seems to splutter.

Specifications

• 2.8 horse power
• A cylinder displacement of 2.8 cubic inch
• An 18 inch bar length
• A total weight of 10.8 pounds

Pros

• Highly reliable

• Can be difficult to start

Jonsered 2036 Turbo Chainsaw Review

This is a highly robust chainsaw that is able to do lots of serious work and still keeps on running over the years. Originally manufactured in the 1990’s it still stands up against some of today’s modern chainsaws.

The 2036 is powered by a 36 cc engine with a horse power of 2.2. The power tool weighs just slightly less than 10 pounds and comes equipped with an anti vibration handlebar system which helps to reduce fatigue.

Specifications

• A 36 cc motor
• 2.2 horse power
• A 16 inch bar length
• An anti vibration handlebar system
• A total weight of 9.9 pounds

Pros

• Is able to do lots of serious work and still keeps on running

Conclusion

It is clear to see from our review of the brand and from some of Jonsered’s chainsaws that they produce high quality power tools. So no matter what particular model you go for you, you can rest assure that you will be getting a chainsaw that will definitely deliver.

However, from the ones we looked at, we would recommend the 2245 over the other two models. Not only does it come highly rated from the professionals but it also has that extra power to that will allow you to tackle the biggest of jobs with absolute ease.

Troubleshooting Manual

We have created Jonsered Chainsaw troubleshooting manual to help our users solve some basic problems with their Jonsered Chainsaws without the need of going to a service station. You will find here guides on chainsaw functionality as well as small repairs or adjustments to the hardware. We have determined the main areas with most typical chainsaw related issues and tried to address those primary. If you would like to ask a direct question please use our FAQ section.

Safety first!

Chainsaw are highly dangerous equipment and no one without proper knowledge or qualifications should use. Most accident results in serious health damage and many cases finish with death. Always when using, repairing or adjusting your chainsaw wear full set of safety clothes. Never wear any kind of jewelry like watch or wedding ring or loose clothes as those very often get catches by chainsaw moving parts and are number one reason causing heath injuries. Chainsaw noise emition is high- most Jonered chainsaws emit noise at a level 115-120 dB- always use hearing protection. Face-mask, helmet, boots and steel toecap shoes should be used at all times.

Chainsaws should be used during the sunny days, as they don’t operate well under humid conditions. Never use the chainsaw when you are tired or in the condition that affects your physical control. You should start your chainsaw when it is away from anything- don’t start the engine while keeping the chainsaw on the tree trunk edge. Always check the chainsaw electric condition before usage and don’t use it if you observe any damage on it.

Inspect the chainsaw and power cable before use. Do not use a chainsaw with a damaged cable. If replacement of the supply cable is necessary, this must only be done by an approved Husqvarna service dealer in order to avoid a safety hazard. Handles should never be greasy, so that your hand can’t slip on it.

Before switch on the chainsaw and at all time while you are using it make sure that your footing is secure. The Chainsaw chain should touch nothing else that the wood it is cutting. After switching on/ releasing the power trigger chain will start to rotate. Whenever troubleshooting you need to switch off the power and wait for it to cool down. Servicing should be performed only by approved dealers. Only basic maintenance should be done by operators. Before each an every usage chainsaw should be checked for any damages and not used if such observed. Chainsaw should be stored in a safe, cold and dry place away from any reach of children.

Kickbacks troubleshooting

Most common danger causing number of accidents are kickbacks. Kickbacks always occurs in the same direction as the guide bar (guide bar and saw are suddenly thrown back towards the operator). They always occur suddenly and without warning. The chainsaw itself may however be thrown in other directions and that often depends from the saw position at particular moment.Sometimes kickback is so strong that it can throw a appliance back at the user causing sever or even fatal injury. Most kick backs are small, but in case the violet one you should always grip your chainsaw very firmly. The left hand should be positioned on the front handle be and the right hand should be on the rear handle.The most common kickback causes are:

• wrongly sharpened cutters
• wrong chain
• wrong guide bar combination
• not proper chain link or/and facing material

Also most accidents kickback take place when connected with limbing. Always make sure that there are no objects nearby that may make you loose your balance or trip over. Chainsaws should’t be used to cut above shoulder height or operated with only one hand!

Whenever you work in the kickback zone set the bar nose radius to smallest possible and make sure that the cutters are well sharpened. Every chain aw is equipped with a chain brake designed to stop the chain instantaneously in the event of a kickback. This function reduces the risk of accident, but it doesn’t prevent it totally. Once chain brake is activated it works in the opposite direction to the force of the kickback. The slip clutch is additionally designed to protects the saw from the overload. Whenever you observe that you chainsaw stop working while the motor was still running it means that it was overloaded. In instances when chainsaw jams in the tree, you should immediately stop the chainsaw and free it.

Once the kickback guard is moved forward chain brake will also get activated. The kickback guard function is to primarily minimize the danger of contact with the chain when operator is not holding the front handle strong enough. Chain brake should be used when you change position or carry your appliance from one place to another

You can manually activate the chain brake by pulling back the kickback guard towards the front handle. Most kickbacks are to small to activate the chain brake. Never let go the grip once chain brake gets activated. In instances when the kickback is violent enough and the left hand is too far from the kickback guard, the chain brake will get activated by the inertia. Often with middle violet inertia is the only option that will activate the chain brake, but like it happens with the manual activation, it will not work in every case.

Troubleshooting

Inertia chain brake function check

Hold the running saw level with the guide bar approximately 45 cm above a stump or other solid wooden object. Release the power trigger. Release the front handle. Allow the the chainsaw pivot in your right hand. The guide bar will fall down and strike the stump. Once the bar nose will hit the stump your brake will be activated

Manual chain brake function check

Your chain brake status and its functionality should be checked every time you use the appliance. Holding the running saw firmly with the the right hand on the rear handle and the left hand on the front handle. Move your left wrist, push the kickback guard- this will activate the chain brake. Don’t let the front handle go. You will observe that the chain will stop at that very moment. If you observe different behavior your chainsaw will need to be taken to the service and repaired by authorized people. Don’t attempt to repair it yourself.

Kickback guard functional verification

Check kickback guard for any defects, move kickback guard to verify that it moves freely without being loose

Table 1. Most common Jonsered Chainsaw faults and its solutions

Mounting guard bar and chain adjustment

Most commonly wear causes chain loosening. Chain should be tensioned regularly before each usage or at the time when you refill the chain oil.

Make sure that the chain brake is not applied- this should be done by pulling kickback guard back against the front handle. Remove the drive cover by screwing out the guide bar nut. With the top cutters facing toward fit the chain around guide bar nose. Hold the chain over the guide bar nose. Once done move the back end of the guide bar towards the drive sprocket at a approximately 45° angle. The free end of the chain should be passed around the drive sprocket. The guide bar should be swung against the power head and over the mounting bolt. Move the chain towards the guide bar groove. The guide bar tensioner pin should be put in its hole in the guide bar. Now replace the cover of the chain drive and screw back the mounting nut.

Chain can be tensioned by the tensioing screw being screwed clockwise. It needs to be tighten firmly, make sure it doesn’t move easily when you try it by hand, use gloves. Once done release the chain brake. Tighten the mounting nut. Verify the new chain tension before each chainsaw usage.

Chain catcher functionality and troubleshooting

The chain catcher purpose is to catch a chain which jumps out of its groove or breaks. It is very rarely occurring fault and doesn’t happen in properly maintained equipment. Before each chainsaw usage make sure that they chain catcher doesn’t have faults.

Right hand guard functionality

The right hand guard is to protects in the event that the chain jumps out of its grove or/and breaks. It is also keeping away branches, twigs and leafs from getting in contact with the grip or right handle. Right hand guard should be inspected before each usage and chainsaw shouldn’t be used if it is damaged.

Slip clutch functionality

Slip clutch protects from overload. It requires cleaning, especially after extensive periods of operation.

Overload protection 2000W

Each Jonsered chainsaw is equipped with the 2000W electronic overload protection, that trips whenever the chainsaw is overloaded. To activate your chainsaw after trip loose the power trigger make sure that the chain is in the right position and has a right tension and the press the power trigger again.

Maintenance of the cutting parts

Proper maintenance of the cutting parts reduces the possibility of kickbacks as well as frequency of the chain breakage Thanks to proper maintenance operators are achieving desired effect and long life of the equipment. Only Jonesered spare parts should be used for replacement. Cutter teeth should always be properly sharpened and chain well tensioned. Not properly tensioned chain causes faults in guide bar and drive sprocket. Chain oil should be filled or replaced every 30 hours of usage.

Guide bar and chain lubrication

Both guide bar and chain are lubricated by an automatic oiling system. Only this chain oil that is formulated for cold and hot weather as well as good adhesion are advised to be used. Every oil thickness in cold temperatures and can easily cause oil pump fault or breaking. It is always advised to use Jonsered chine saw EP 90 gear oil could be used, standard motor oil shouldn’t be used

Automatic chain lubrication system verification and troubleshooting

In order to verify correct chain lubrication switch on your chainsaw and direct it into the light color object. Run a chainsaw over it. After approx. a minute you should see a streak of oil spatter on the light object surface- that will mean your chain is lubricated properly. A full lubrication box is enough for approx 20 min long usage.

In most of the case you can refill the lubrication box yourself by following the steps below. However if afterwards your chainsaw doesn’t work properly you should take it to Jonsered service station.

Jonsered 2150 Turbo Chainsaw

1. Verify that the guide’s bar oil passage is clean, if not clean it
2. Verify that the bar groove is clean, if not clean it
3. Verify that the nose sprocket is not clogged and turns easily. Grease if needed.

General instructions regarding cutters

Chainsaw should never be used if the chain is dull. It is easy to recognize that the chain is dull- it is the case each time you need to press your chainsaw toward the wood.Also cot wood will have a shape of small cornflakes. A sharp chain always produces large chips, and the saw will feed itself through the wood.

The depth of the cut is being determined by a difference of depth gauge to the cutter (so called cutting link)

Limbing

As mentioned in the kickback section above most of the kickback happen during the limbing. Be very careful when cutting limbs under the tension.

Crosscutting

You should never attempt to jerk the saw free when it gets stuck in the bush, mostly because chain can hurt you once it suddenly becomes free. When cutting the log on the ground there is a very small chance for the saw jamming, but it is almost impossible to avoid saw getting stuck in the ground. Try to cut straight through the log. Slow down at the end, be prepared for the breakthrough at the end. Best solution is always to stop cutting at around 3/4th of the log, after this turn the log and finish with the remaining part.

When you attempt to cut the log that is supported at one end you should make first cut from below to 1/3 of the full diameter and the finish the cut from above. When you to attempt to cut a log that is supported at both ends start from initial cut from the top to the 1/3 if the full diameter and then finish from below because the chainsaw can jam in the kerf if you try to cut straight through from above.

Cutting thick branches

All rules applicable for cross crosscutting apply to thick branches cutting. Cut branches in several parts. Your foot needs to be safe all the time (moving, standing). General rule is to work with the log towards your right. Keep the chainsaw close to your body.

Danger zone and safe zone

Jonsered 2036 Turbo Manual

A danger zone is more than two times of the height of the tree that will be cut. This danger zone should be free of people while cut. Tree falling should always be directed into the most free space within the danger zone. Any lodging against another tree should be avoided as it is very dangerous. It is common that trees are falling different direction than those aimed by operators that is mostly caused by the shape of the tree, its branches and other factors like wind direction etc. The tree falling should never be directed toward operator. The safe zone starts from 2 and 1/2 height of tree that will be cut.

Notch

Notch is being formatted from: top, horizontal and bottom notch cuts. The main notch can determine the direction in which the tree will fall. Final cut that make a tree to topple over is called felling cut. When cutting the big tree you always need to start from creating a notch, that should start from the top cut (45° downward angled cut ) and use the bottom guide bar, then bottom notch and close the whole with the top notch. Notch depth should always be around 1/4 of the full diameter of the tree. The notch angle should be 45° and the notch line should be horizontal to the falling direction.

Felling cut

Jonsered 2035 Turbo Manual Transmission

The felling cut should be done from the opposite side of the tree. The felling cut should be horizontal. Felling cut should always be done above the bottom notch cut. Cuts should be performed at the full motor speed. Wedge should be put in the feeling cut when the depth of the cut allows it. The felling cut should be parallel to the notch. In most of the cases you should leave the hinge wood at 1/10 if the total tree diameter. In those cases hinge wood will steer the falling direction. You need to pay special attention not to cut through the hinge wood or your falling tree will be out of control. Once felling cut approaches the notch, the tree will start falling with the wedge help or by itself.
