8. MAINTENANCE AND SERVICE
The removal of security mechanisms,
an inappropriate maintenance, the
substitution of the bar and chain with
non original spares could cause severe
corporal damages.
Always carry out maintenance work with the
machine unplugged from the mains.
Carry out the following maintenance checks prior to
working as well as when finishing your job to ensure
the good functioning of this machine in the future.
8.1. EXIT ORIFICE OF THE CHAIN OIL
Dismount the bar and check
that the oil orifice (A) is not
clogged.
8.2. SHARPNESS OF CHAIN TEETH
Attention!: An incorrectly sharpened chain increases
the risk of kick back as well as increasing the vibration
level and possible accidents!
To ensure that the machine cuts correctly, maintain
the chain sharpened. You must also sharpen the chain
if:
• You must place more pressure to cut.
• The cut is not straight.
• There is an increase of the vibration levels.
• When cutting instead of splinters you see shavings.
Do not forget to always use security gloves when
sharpening the chain. Make sure the chain is placed
correctly once it has been sharpened.
Use a special file for chainsaws when sharpening the
chain.
Place the file between points (A) and (B) and push the
file forward maintaining a 30 angle.
File all the teeth of the chain in the same manner,
filing forward at a 30 angle.
Check the security height (C), this height must be
some 0.6mm approximately. A height (C) larger than
0.6mm will cause the chain to bite the wood and
will require a higher work rate from the engine and a
lower height will mean that the chain will cut badly.
Verify the length of the cutting teeth. All teeth must
have the same length. If necessary file the teeth until
all of them have the same length.
8.3. PERIODIC MAINTENANCE
Do periodic maintenance inspections on the
machine to guarantee an efficient use of the machine.
For a complete check up, we highly recommend that
you take the machine to your after sales service.
Maintain the machine clean, specially the ventilating
areas of the engine.
