– Switch on the chain saw and let it run for approx.
1 minute until oil splashes can be seen on the sheet of pa-
per to confirm that oil is being pulled through the auto-
matic lubrication system.
Note: Operating the chain saw without chain oil or when the
oil level is below the minimum mark will result in damage to
the chain saw.
Note: Oil becomes denser at lower temperatures, which de-
creases the flow rate of oil.
Note: Saw chain life and cutting capacity depend on op-
timum lubrication.
Working
Always read the operating and safety information be-
u
fore use.
Always check the tool and chain condition, the oil
u
level and correct assembly before use. Only use the
chain saw if it is in perfect condition.
Always wear suitable clothing and personal protective
u
equipment.
Always make sure that the environment is dry and
u
free from obstacles and persons not involved.
Never use the chain saw on a ladder or above shoulder
u
height.
Never over-reach or work with arms fully extended.
u
Always hold the chain saw firmly with both hands.
u
Always make sure that the power cord is routed to the
u
rear to ensure it does not tangle with branches and
equipment during cutting.
General Behaviour (see figure D)
– First time users should practise cutting logs on a saw-
horse or cradle.
– Hold the chain saw at the right-hand side of your body.
– Use the gripping teeth (12) as a leverage point while cut-
ting.
– The chain must be running at full speed before it makes
contact with the wood.
– Reset the gripping teeth at a lower point when sawing
thicker logs or tree trunks. For this, pull the chain saw
slightly backwards until the gripping teeth release, and re-
Troubleshooting
The following chart lists problem symptoms, possible causes and corrective action, if your machine does not operate properly.
If these do not identify and correct the problem, contact your service agent.
Warning: Switch off and remove plug from mains before investigating fault.
Problem Possible Cause
Chain saw fails to oper- Kickback brake is activated
ate
Plug not connected
Mains socket faulty
Fuse faulty / blown

position at lower level to continue sawing. Do not remove
the chain saw completely out of the cut.
– Do not force the saw chain while cutting, let the chain do
the work.
– Always remove the chain saw from a wood cut while the
saw chain is running.
– Beware when reaching the end of the cut. The weight of
the chain saw changes unexpectedly as it cuts free from
the wood. Danger of injury to the legs and feet.
Kickback (see figure E)
– Kickback is the sudden backward/upward motion of the
chain saw, occurring when the chain (at the tip of the
chain bar) comes in contact with a log or wood, or when
the chain becomes jammed.
– When kickback occurs, the chainsaw reacts unpredict-
able and can cause heavy injuries to the operator or
bystanders.
– Particular attention must be given when sawing side-
wards, slanted or during length cuts, as the gripping teeth
(12) usually can not be applied.
Cutting Logs (see figures F)
– Always secure the logs before cutting.
– Always cut the logs beyond the secured points to prevent
the log from closing in and causing the chain to get
jammed.
– Never allow the saw chain to make contact with the
ground or cutting equipment.
– Be careful not to trip over tree stumps, branches, roots,
etc.
Cutting Wood under Tension (see figure G)
– Be extremely careful when sawing wood, branches or
trees under tension. Leave saw jobs like these to trained
professionals. There is a high risk of accidents.
Limbing a Branch or Tree (see figure H)
– Limbing is removing the small branches from a fallen tree
or large branch.
– Leave larger lower limbs to support the log off the ground.
– Remove the smaller limbs in one cut.
Corrective Measure
see figure C2
Connect plug
Use another socket
Replace fuse
