Harvester head – safe handling of the saw assembly
The saw assembly includes sharp elements, such as a saw chain. Therefore, our priority should be the appropriate tools and personal protective equipment in the form of protective gloves.
If the saw chain breaks, individual links can be thrown out at high speed, posing a serious safety hazard. Therefore, avoid standing in front of or behind a running chainsaw. On the other hand, avoid also crosscut felling when the cabin is on the sawing line.
The hydraulic system should never be modified to increase chain speed. The recommended pressure in the automatic chain tensioning device should be adhered to in order to avoid shortening the service life of the sprocket, chain and guide bar.
Before starting work with the cutting chain, it is worth making sure that the engine is turned off and we are equipped with protective gloves. Always remove the chain for adjustment or maintenance.
If the saw does not have automatic tensioning, check and adjust the chain tension regularly.
In addition, the correct operation of the chain lubrication system is important, which should be checked periodically.
Checking the chain for cracks, bent links, etc. is essential. Damaged components should not be used, so when equipment needs to be removed, there are few important things to keep in mind:
• When replacing a chain, it should be sharpened and inspected to reduce the risk of breaking the chain and splitting the wood
• Due to friction, the guide bar and chain heat up very quickly, so it’s best to wait a few moments before servicing
• When replacing the bar and chain with a new one, lubricate the equipment before first use
• The position of the bar and sprocket can be corrected using shims.
Of course, the key aspect is also the selection of only high-quality chains, guides and sprockets wheels from reputable manufacturers.
In conclusion, the safe use of a harvester head should never be underestimated. It is essential to follow all instructions and to perform regular technical inspections of the equipment. Knowing how to properly manage and control your machine will help you reap maximum benefits and minimize the risk of accidents at work. Consistent implementation of good practices can not only protect you, but also your colleagues and the company from costly incidents resulting from the negligence or improper operation of this type of machinery.
