8. MAINTENANCE AND SERVICE

8.1. CARE AND MAINTENANCE AFTER USE
Carry out the following operations when you have
finished the cutting procedure to ensure that the
machine is kept in a perfect condition.
8.1.1. CHAIN OIL LUBRICATION HOLE
Unassembled the
guide bar and
check that the
oil hole (1) is not
blocked.
8.1.2. SHARPENING OF THE CHAIN TEETH
WARNING! : An improperly sharpened chain increases
the risk of rebound and vibrations increasing the risk
of injury!
To ensure a smooth and safe cut keep the teeth on
the chain sharpened. The cutting teeth need to be
sharpened when:
• On cutting, sawdust appears instead of splinters.
• When sawing, extra effort is necessary.
• The cutting path is not straight.
• Vibration increases
• There is an increase in fuel consumption.
When you sharpen the teeth, make sure you
are wearing heavy duty gloves. Make sure
the tool chain is safely attached.
Make sure the engine is stopped.
Use a special rounded chainsaw file of the
correct size for the chain.
Place the file on the cutting tooth between the cutting
edge (A) and the depth gauge (B); and apply light
pressure forwards keeping an angle of 30º filing the
cutting edge of the tooth.
First file the teeth on one side, always using outward
movements and maintaining the 30º angle, and then
file teeth on the other side.
Check the height of the safety gauge (C), which should
be around 0.6 mm. If the height of "C" is too low, it
will mean the chain will not cut well and if it is too
high, it will mean the chain will "bite" the wood too
much, causing the engine to overwork.
Check the length of the cutting teeth. All the teeth
must be of the same length. If necessary, file the long
teeth until they are all of the same length.
