Cutting limbs of fallen trees
Check if to which side the limb is bent. Than make the initial
cut from the bent side and finish by saving from the opposite
side.
WARNING! Be alert the springing back of a cut limb
Pruning a sanding tree
Cut up the bottom, finish down the top.
WARNING!
Do not use an unstable foothold or ladder.
Do not overreach.
Do not cut above shoulder height.
Always use both hands to hold the tool.
Cause and prevention of the kickback
Kickback may occur when the nose or tip the guide bar touches an object, or when the wood closes
in and pinches the saw chain in the cut.
Tip contact in some cases may cause a sudden reverse reaction, kicking the guide bar up a back
towards the operator.
Pinching the saw chain along the top of the guide bar may push the guide bar rapidly back towards
the operator.
Either of these reactions may cause to lose control of the saw which could result in serious
personal injury. Do not rely exclusively upon the safety devices built into your saw. As a chainsaw
user, you should take several steps to keep your cutting jobs free from accident or injury.
Kickback is the result of tool misuse and incorrect of operating procedures or conditions and can
be avoided by taking proper precautions as given below:
•
Only use replacement bars and chains specified by the manufacturer. Incorrect replacement
bars and chains may cause chain breakage and/or kickback.
•
Follow the manufacturer’s sharpening and maintenance instructions for the saw chain.
Decreasing the depth gauge height can lead to increased kickback.
Chainsaw oil
The lifetime of the chain and guide bar depends greatly on the quality of lubricant used. Choose a
chain lubricant that is environment friendly. Use quality chainsaw oil without sticking additive for
lubricating the saw chain and guide bar.
Do not use used or recycled oil as it could damage the oil pump. Used oil does not have the
required lubricating properties for lubricating the saw chain and in addition, it is harmful for the
environment.
Oils for saw chains stick when not being used for longer time. This can cause damage to oil pump
or parts leading the oil. Therefore, prior storage:
o
Empty the oil from oil tank
o
Fill in the tank with little engine oil
o
Allow the chainsaw to run for some time to enable the oil leading and oil pump clean.
o
Before other use of the chainsaw refill tank with the oil for saw chain again.
Store oil in certified containers (such as jerry cans).
Filling oil tank
Clean the oil filler cap and its circumference before opening it, so as to avoid impurities getting
inside the tank.
Fill the tank.
Screw the oil tank cap and wipe away any oil spills.
