Useful tips when working with a chainsaw

The chainsaw is a great tool for cutting wood, featuring high performance and reliability. But before you start working with it, you must carefully read the attached instructions and perform a number of preparatory operations. They will help to avoid damage to the unit and ensure its safe operation. The tips provided here for working with chainsaws are based on the recommendations of equipment manufacturers and the experience of professional craftsmen.

Preparing chainsaws for work

If the instruction manual of the chainsaw has been studied by you, and you have figured out the location and principle of operation of all its components, you can start preparing the first run of the tool.First, an external examination is convinced of the complete completeness of the chainsaw and in the absence of visible damage. The guide tire must be fixed in its proper place, and the cutting chain is inserted into its grooves and engaged with the sprocket.

Chain tension check

It is important that the chain has an optimum tension. When too tight, the load on the engine will increase, and loosening of the engagement can lead to dislodging and jamming parts. Pull the chain in the middle of the tire up to check. In this case, its shanks should extend from the groove by a few millimeters. If this does not happen or there is a strong sagging, it is necessary to adjust the position of the tire.

Filling with fuel and lubrication oil

In accordance with the recommendations of the manufacturer, the fuel mixture is prepared from gasoline of the specified brand and oil for two-stroke carburetor engines. The ratio for most foreign models is 1:40 or 1:50. Fuel is poured with the fuel tank cap removed, indicated gas station icon. Separately, chain lubrication system marked the image of a dropFilled with engine oil type W30-W40.

Often, manufacturers are advised to use their own brand brand.

The first launch of a chainsaw

New chainsaw can not be immediately operated under maximum load. All rotating parts of the tool must first get used to each other. It is recommended that when you first start to run a full gas tank, without applying high effort to the saw. If this test was successful, you can subsequently saw a chainsaw without additional restrictions.

Launch chainsaws are produced on flat horizontal area. The starting order for the example of the Stihl saw should be as follows.

1. Stretch the chain by hand along the tire, making sure that the ride is smooth and there is no excessive resistance.
2. Turn on the chain brake by moving its handle away from you.
3. Open the cylinder decompression valve.
   

4. A few clicks on the primer to file the fuel mixture in the carburetor.
   
5. In order to start the saw correctly, it is necessary to press the rear handle with the right foot to the ground. Holding the front handle with your left hand, with your right hand lock the fuel lever in the working position.
6. Put the combination switch in the cold start position.
7. With a jerk of the starter handle, start the ignition of the engine, which should almost immediately stall.
   

8. Open the throttle to the half gas position.
   

9. A second jerk of the starter rope to restart the engine, immediately switching the fuel lever to the idling position.
   
10. Pull the handle of the chain brake towards yourself by moving it to the working position.
11. Holding the far end of the guide rail to a clean and bright surface, make sure that the chain lubrication system works by spraying small drops of oil.

Making sure that all the knots and mechanisms of the saw are intact and do not emit extraneous noise at idle, you can proceed to work under load.

Security measures when working with a chainsaw

When purchasing such a tool, you need to know how to properly use a chainsaw. Labor protection requires an employee to use only serviceable equipment. Therefore, the operation of the chainsaw requires:

• her compulsory inspection before each launch;
• regularly checking the status and settings of the main nodes;
• timely add oil and adjust the chain tension;
• termination of work when a failure of the brake circuit and other important parts and accessories.

Do not make home-made changes in the design of the tool or use unsuitable for the used model spare parts. Some craftsmen talk about how to start a chainsaw no starter. But they forget that his impeller is needed to cool the motor, which will start to overheat with the threat of failure.

Chainsaw can only work in workwear with the use of special gloves, shoes with metal inserts, helmets and eye protection. In this case, the tool is held with two hands with a straight back, not bending far forward and not raising the saw above the shoulders. It is not recommended to place body parts in the plane of the cut. Safety precautions do not allow to move with a chainsaw, in which the cutting chain rotates.

Practical work with a chainsaw when felling trees and cutting branches requires compliance with special rules to prevent injury to an employee by falling trunks. Especially dangerous is the reverse blow of a saw that stumbles upon an obstacle. The logger cannot:

• cut trees at one time;
• simultaneously cut several boughs;
• cut through the end of the tire;
• be in the fall zone of the tree.

It is not recommended to work with a chainsaw in the rain, as the risk of slipping increases with a working tool in your hands.

Maintenance of chainsaws

Chainsaw maintenance includes:

• clean and dry condition;
• timely adjustment of all components and assemblies;
• replacement of worn parts with new ones.

It is necessary to regularly maintain the chainsaw, performing the following operations:

• adding fuel mixture and oil to lubricate rubbing surfaces;
• regulation of the chain tension, which lengthens over time;
• lubrication of the tire sprocket;
• blowing or flushing the air filter;
• cleaning the combustion chamber of the cylinder;
• Replacement of the chain, guide rail and drive sprocket upon abrasion of more than 0.5 mm from the nominal size.

All maintenance work on the chainsaw is performed only with the engine off.

If it is necessary to stop working for a long time, all chainsaw units are thoroughly cleaned.. In this case, metal parts are covered with lubricant, and the chain is removed and immersed in oil. Fuel must merge. It is recommended to store such tool in a warm and dry room.

Following the guidelines listed in this article will help you operate the chainsaw efficiently and safely for the life expectancy of the manufacturers.
