9. Working instructions

Transporting the chainsaw
Before transporting the chainsaw, always remove
the plug from the power socket and slide the chain
guard over the rail and chain. If several cuts are to
be performed with the chain saw, the saw must be
switched off between cuts.
Securing the extension lead
Only use extension leads suitable for outdoor use. The
cross section of the cable (max. length of extension
cord: 75m) must be at least 2,5 mm². secure the
chainsaw flex to the extension lead by inserting the
extension lead into the strain relief gap of the housing
(Fig..M).Extension leads longer than 30 m will reduce
the performance of the chainsaw.
Chain lubrication
To prevent excessive wear, the saw chain and guide
bar must be evenly lubricated during operation.
Lubrication is automatic. Never work without chain
lubrication. If the chain runs dry, the entire cutting
apparatus will quickly become severely damaged.
It is therefore important to check both chain lubrica-
tion and the oil gauge every use (Fig. 4).
Never use the saw when the oil level is below the
"Min." mark.
• Min.: When only approx. 5 mm of oil is visible
at the lower rim of the oil gauge (15), you must
top up with oil.
• Max.: Top up with oil until the window is full.
Chain lubricants
The service life of saw chains and guide bars depends
to a large extent on the quality of the lubricant used.
Old oil must not be used! Use only environment-
friendly chain lubricant. Store chain lubricant only in
containers which comply with the regulations.
Guide bar
The guide bar (7) is subjected to especially severe
wear and tear at the nose and the bottom. To avoid
one-sided wear and tear, turn the guide bar over
every time when you sharpen the chain.
Chain wheel
The chain wheel (16) is subjected to especially high
wear and tear. If you notice deep wear marks on
the teeth, the chain wheel must be replaced. A worn
chain wheel curtails the service life of the saw chain.
Have the chain wheel replaced by a specialist dealer
or your Customer Service.

Chain guard
The chain guard must be clipped onto the chain and
sword as soon as the sawing work has been completed
and whenever the chainsaw has to be transported.
Chain brake
In the event of kick-back, the chain brake (3) will be
actuated via the front finger guard. The front finger
guard is pushed forwards by the back of the hand
and this causes the chain brake to stop the chain
saw, or rather the motor, within 0.15 s (Fig 5, H).
Releasing the chain brake (Fig. 5)
To be able to use your chain saw again, you must
release the saw chain again. First switch off the
chainsaw. Then push the front finger guard (3) back
into the vertical position until it locks in place (Fig
5, I). The chain brake is now fully functional again.
Chainsaw protection
Never use the chainsaw in the rain or in damp
conditions.
Warning! If the extension cable is damaged, pull the
plug out of the power socket immediately. Never work
with a damaged cable.
• Check the chainsaw for damage. Before using your
tool again, check the safety devices or any slightly
damaged parts to ensure that they are in good
working order.
• Make sure the moving parts are working correctly.
• All the parts must be correctly assembled and
meet all the conditions required to ensure that the
chainsaw works correctly.
• Any damaged safety devices and parts must be
properly repaired or replaced immediately by a
Customer Service workshop, unless there are
instructions to the contrary in these operating
instructions.
Notes on working practice
Kick-back
You can avoid accidents by not sawing with the tip of
the guide bar as this may cause the saw to rear up
suddenly. Always use the complete safety equipment
and clothes when working with the saw. Kick-back is
an upward and/or backward movement of the guide
bar which can occur if the saw chain at the tip of the
guide bar encounters an obstruction.
Make sure your work-piece is firmly secured.
Use clamps to stop the work-piece slipping. This
also makes it easier to operate the chainsaw with
both hands. Kick-back causes the saw to behave
uncontrollably and thus brings with a slack or blunt
chain. A poorly sharpened chain increases the risk of
kick-back. Never saw above shoulder height.
