Useful tips when working with a chainsaw

The chainsaw is a fantastic tool for cutting wood, known for its exceptional performance and reliability. However, it’s important to take the time to carefully read the included instructions and carry out a series of preparatory steps before using it. By doing so, you can prevent any potential damage to the machine and ensure that you can use it safely. The helpful tips provided here for working with chainsaws are based on recommendations from the manufacturers of these tools as well as the expertise of experienced craftsmen.

Preparing the chainsaw for work

If you have already familiarized yourself with the chainsaw’s instruction manual and have a clear understanding of the location and functioning of all its parts, you can proceed to prepare for the initial use of the tool. Before anything else, it is important to ensure that the chainsaw is fully intact and free from any visible damage. Take a moment to securely fasten the guide bar into position and carefully insert the cutting chain into its designated grooves, ensuring it is properly aligned with the sprocket for optimal performance.

Checking chain tension

Ensuring that the chain is properly tensioned is crucial. Having it too tight will put excessive strain on the engine, while loose engagement can result in parts becoming dislodged and causing a blockage. To check, pull the chain upwards from the center of the tire. The links should come out of the groove by a few millimeters. If this does not occur or if there is considerable slack, the tire position needs to be adjusted.

Filling with fuel mixture and chain oil

Following the guidelines of the manufacturer, it is necessary to prepare a fuel mixture consisting of a specific brand of gasoline and oil suitable for two-stroke carburetor engines. For most foreign models, the recommended ratio is 1:40 or 1:50. The fuel should be poured into the fuel tank, which can be identified by the gas station icon, after removing the lid. Additionally, the chain lubrication system, indicated by a drop symbol, should be filled with machine oil of the W30-W40 type.

It is common for manufacturers to advise using their own brand of fuel and oil.

Starting the chainsaw for the first time

It is not recommended to use a new chainsaw at maximum load right away. It is important to allow the rotating parts of the tool to first come into contact with each other. For the initial start, it is advised to have a full gas tank and avoid applying excessive force to the saw. Once this test is successful, the chainsaw can be used for subsequent cutting without any additional restrictions. The chainsaw should be started on a flat and level surface. The starting procedure for a Stihl chainsaw is as follows:

1. Manually pull the chain along the bar to ensure smooth operation and no excessive resistance.
2. Engage the chain brake by pulling the chain brake handle towards you.
3. Turn the valve for decompressing the cylinder.
4. Inject the fuel mixture into the carburetor by repeatedly pressing the primer.
5. To properly start the chainsaw, place your right foot against the ground and press the rear handle. Hold the front handle with your left hand and lock the fuel lever in the working position with your right hand.
6. Adjust the combination switch to the cold start position.
7. Pull the starter handle with a quick jerk to start the engine, which should quickly stall.
8. Turn the throttle to the halfway position.
9. With another pull of the starter rope, restart the engine, immediately moving the fuel supply lever to the idle position.
10. Pull the chain brake handle towards you to engage it.
11. Place the far end of the guide bar against a clean and smooth surface and check the chain lubrication system by splashing small drops of oil.

After ensuring that all parts and mechanisms of the saw are functioning properly and not making any noise when idle, you can start working under load.

Safety precautions when working with a chainsaw

When purchasing a chainsaw, it is crucial to have a good understanding of its proper usage. Occupational safety regulations mandate that employees use only well-maintained equipment. Consequently, operating a chainsaw entails:

• Conducting a mandatory inspection before each use;
• Regularly inspecting and adjusting the main components;
• Timely adding oil and adjusting chain tension;
• Ceasing work if the chain brake or other vital parts and accessories are defective.

It is important to refrain from making any makeshift modifications to the tool and using incompatible spare parts. Some craftsmen may explain how to start a chainsaw without a starter. However, they fail to mention that the impeller is crucial for motor cooling, as the motor could overheat and risk failure.

When working with a chainsaw, it is essential to wear full protective gear, including overalls, special gloves, shoes with metal inserts, a helmet, and eye protection. The chainsaw should always be held with both hands, maintaining a straight back and avoiding leaning too far forward or lifting the saw above shoulder height. It is important to avoid positioning any part of the body in the cutting plane. Additionally, safety regulations strictly prohibit moving while the chainsaw’s cutting chain is rotating.

When it comes to practical work involving the use of a chainsaw for felling trees and cutting limbs, it is essential to adhere to specific safety guidelines in order to protect against potential injuries caused by falling trunks. One particular hazard to be wary of is the back blow, which can occur when the saw strikes an obstacle. To minimize the risk of harm, it is crucial for loggers to avoid the following actions:

• Attempting to fell trees in a single cut
• Simultaneously cutting multiple limbs
• Using the end of the tire for cutting
• Remaining in the vicinity of a falling tree

Working with a chainsaw in rainy conditions is highly discouraged due to the increased likelihood of slipping while handling the tool.

Chainsaw maintenance

Caring for a chainsaw involves:

• Keeping it clean and dry;
• Regularly adjusting all components and assemblies;
• Replacing worn parts with new ones.

To ensure proper maintenance of the chainsaw, it is important to perform the following tasks:

• Adding fuel mixture and oil to lubricate the friction surfaces;
• Adjusting the chain tension as it tends to loosen over time;
• Lubricating the idler sprocket on the guide bar;
• Blowing or flushing the air filter;
• Cleaning the combustion chamber of the cylinder;
• Replacing the chain, guide bar, and drive sprocket when they are worn beyond 0.5 mm of their original size.

All maintenance work on the chainsaw should be done only when the engine is not running.

If you need to pause working for an extended period, it is essential to perform a thorough cleaning of all components of the chainsaw. Ensure that the metal parts are generously coated with grease, and remove and submerge the chain in oil. Drain the fuel completely. For optimal storage, it is advisable to keep the chainsaw in a warm and dry environment.

By adhering to the guidelines outlined in this article, you can effectively and safely operate your chainsaw throughout its recommended lifespan, as indicated by the manufacturers.
