Maintenance and care
7.4 Cutting converted timber
Heed the following points during this work:
■
Use a secure cutting surface (sawing trestle,
wedges, beams).
■
Make sure you are standing securely and
that your bodyweight is evenly distributed.
■
Secure logs to prevent them twisting.
■
Only start the cut once the saw chain is run-
ning. Never switch on the chain saw already
in the kerf.
■
Do not secure the wood with your foot and do
not get another person to hold it.
8 MAINTENANCE AND CARE
WARNING!
Danger of cutting injuries
Danger of cutting injuries when reaching
into sharp-edged, moving appliance
parts and into cutting tools.
■
Before maintenance, care and
cleaning work, always switch off the
appliance. Remove the recharge-
able battery.
■
Always wear protective gloves
during maintenance, care and clean-
ing work.
The chain saw complies with all relevant safety
standards. Repairs are only allowed to be per-
formed by qualified specialists, and with the ex-
clusive use of genuine spare parts.
■
After each use, check the chain saw for wear
and renew any damaged components.
■
Do not get the machine wet or expose it to
moisture. Clean plastic parts with a cloth and
do not use any cleaning agents or solvents.
■
Clean the cooling air slots if they are blocked.
■
Do not spray the chain saw not with water
and do not use a high-pressure cleaner.
■
Only use spare parts specified by the manu-
facturer.
8.1 Checking the chain tension
Frequently check the chain tension, because new
saw chains stretch.
At operating temperature, the saw chain stretch-
es and hangs down.
NOTE
The saw chain has been tensioned cor-
rectly when:
■
It is in contact with the underside of
the guide rail and can be pulled
through by hand
■
It can be lifted by 3 – 4 mm in the
middle of the guide rail
CAUTION!
Danger of injury due to the saw chain
jumping off!
An insufficiently tensioned saw chain
can jump off during operation and lead
to injury.
■
Frequently check the chain tension.
The chain tension is too low if the
drive links come out of the groove
on the underside of the chain bar.
■
Re-tension the saw chain properly if
the chain tension is too low.
8.2 Sharpening the saw chain (26)
DANGER!
Danger of fatal injury due to kick-
back!
The operator can be fatally injured by
kickback of the chain saw.
■
Sharpen the saw chain properly.
NOTE
Inexperienced chain saw operators are
recommended to have the saw chain
sharpened by a specialist at the custom-
er service.
The saw chain must always be well-sharpened
for reasons of safety and efficiency.
Sharpening is required if:
■
The saw chips are like sawdust.
■
Greater force is necessary for cutting.
■
The cut is not straight.
■
Vibration increases.
If you get trained customer service personnel to
sharpen the chain for you, they will be able to do
this with the appropriate tools for a minimum of
material removal and even sharpening of all
teeth.
You can sharpen the saw chain yourself using
special round files whose diameters are adapted
