Sturm chainsaw: instruction manual
The efficiency of any tool, the safety of equipment and the provision of safe conditions for its use is ensured first of all by itscorrect operation. A feature of chainsaws is their high potential for injury. Therefore, one of the main components of the rules for the operation of equipment is safety requirements.

- serviceability of all nodes and mechanisms;
- presence of a sharp properly tensioned chain;
- fullness of fuel and oil tanks;
- correctly adjusted carburettor.
How to keep the tool in good condition?
The authors of the reviews are convinced that in order to ensure the smooth operation of the chainsaw, it must be properly maintained. The main operations that maintain the he alth of the tool are:
- cleaning air filters;
- carburetor adjustment;
- cleaning the spark plug;
- adjusting the gap between its electrodes;
- chain sharpening;
- replacement of wearing parts.
A new chainsaw must be run in at low speed for 40-50 minutes, then turned off and additionally check the chain tension. Then a few trial cuts are made, without any effort, and only after that they start working in normal mode.
About setting and adjusting chain tension
Storm chainsaw chainis one of the most important elements of their device. With the installation of a new or already used sharpened chain on a chainsaw, they begin to prepare the tool for work. Chain parameters (pitch and shank thickness) must match the installed bar.
Types of tensioners
There are two types of chain tensioners on chainsaws:
- linear standard;
- quick acting.
Experts recommend using the traditional linear mechanism as a more efficient one, for the implementation of which you should:
- Unscrew the nuts and remove the chain sprocket cover.
- Before mounting or removing the chain sprocket guard, reviewers advise loosening the chain brake by pulling the brake stop towards the handle.
- The chain is started by the clutch, put on the drive sprocket and put on the tire. The cutting edge of the tooth on the upper branch of the chain must be directed forward. It is necessary to ensure that the chain is easy to pull, the clutch drum is easy to handle when it is moving.
- After that, rotate the tension screw forward until the shanks of the lower branch enter the groove of the tire and lie against its lower edge.
- The final adjustment of the chain tension, as well as the tightening of the bar, is done after the cover is in place and the fastening screws are pre-tightened (not completely)
What does it mean: correctly tightened chain?
As follows from the recommendations of experts shared by users on the Internet, a signA properly tensioned chain is no slack at the bottom and not too tight. The first can be checked visually, the second is checked by pulling the chain along the bar with your hand. To avoid cuts, this operation should be carried out in protective gloves. If you can see that the bottom of the chain is touching the edge of the bar and the chain is moving freely, then the chain is properly tensioned.
How does the Sturm chainsaw start?
Well-tuned and adjusted equipment, as the authors of the reviews assure, it is easy to start in any conditions.
- Before starting the chainsaw "Storm" is installed on level ground. In this case, the tire should not touch the ground. The chain brake must be activated, i.e. moved to the end of the bar.
- When starting, hold the front handle of the saw with your left hand, and press the rear handle to the ground with your right foot.
Sturm chainsaw: working methods and safety measures
Users recommend:
- Before you start working with the tool, you need to make sure that all its components and mechanisms are in good condition.
- It is necessary to ensure the stable position of the equipment, nothing should be under the feet, as excess items can lead to imbalance or fall of the worker.
- Sawing starts with the moving chain. You can cut with both the lower and upper branch of the chain, but the first method is considered the main one (the saw is carried forward, the teeth rest against the tree). If you cut with the upper branch,the saw is pushed towards the operator.
- It is forbidden to cut several branches (trunks) at the same time. It is necessary to ensure that while sawing one branch (trunk), the tool does not come into contact with neighboring ones.
- Trunks with internal bending stress are filed first from the side of the compressed fibers, and finally cut from the side of the stretched ones. Otherwise, the chain and bar may be caught in the cut.
- Care must be taken when sawing split trees: the wood chips can be caught and ejected by the chain. In addition, split trees sometimes pinch the tire.
- When sawing trees lying on the ground, they must be securely fixed to prevent rolling. The optimal position of the logs is stacking on the trestle.
- Trees are felled with two cuts: cutting and cutting.
About renovation
The authors of the reviews assure: those who have a broken Sturm chainsaw should not be upset. The starter in it is the most problematic element in this regard. But if you have experience, following the requirements of the instructions, it is absolutely easy to repair it yourself.
How to remove the starter?
- Remove the side cover of the housing by unscrewing the screws and detaching the fixing latches.
- Unscrew the screw that holds the starter, set aside.
- Remove and set aside the starter clamp and (if equipped) the soft start spring.
- Disconnect pulley and rope.
- On a corduntie the knot, pull the rope out of the pulley.
- Remove the pulley from the cover.
How to diagnose?
- Inspect the pulley (check for breaks and cracks). According to experienced users, the starter may not work due to damage to the pulley on the rear.
- Inspect the spring. Reviewers claim that the spring, like the case, can be damaged at the attachment point, most often where it is visible during disassembly.
How to assemble the starter?
After installing the cord, you need to pull it slightly and not let it slip off. It is possible to scroll and "departure" from the mount. In this case, the spring may jump out of the starter. Netizens advise to avoid this by:
- Replace pulley (install over starter spring and make sure clutch is present).
- Wrap the pulley (it should “pull” the cable into the starter). Four to five turns are enough to set the desired voltage.
- Attach the rope. In this case, it is better to use the services of an assistant. But it is possible to perform this procedure on your own. It is necessary to match the holes in the pulley and in the starter housing. Pass the rope through both holes, tie a knot at the end, take the rope to the side.
- Install starter clip.
- If necessary, replace the soft start spring. Then install the starter clamp in place and tighten the screw.
- Coil the rope.
- Reinstall the cover and tighten the screws.
