- the chain life of the saw chain mainly depends upon
sufficient lubrication and correct tensioning
- avoid tensioning the chain if it is hot, as this will cause
the chain to become overtensioned when it cools down
• Lubrication !
Chain life and cutting capacity depend on optimum
lubrication; therefore the chain is automatically oiled
during operation via oil outlet L 2
! the chain saw is not supplied filled with oil; it is
essential to fill with oil before use
! never operate the chain saw without chain oil or
at an empty oil reservoir level, as this will result
in extensive damage to the product
- set chain saw on any suitable surface with oil reservoir
cap M facing upward
- unscrew cap and add chain saw oil (not included)
until reservoir is full
- avoid dirt or debris entering oil reservoir
- mount oil reservoir cap and tighten
! check oil level prior to starting and regularly
during operation; refill oil when oil level is below
indicator N
- the oil reservoir filling will last approx. 15 minutes,
depending on sawing intensity and stops
- never use recycled/old oil
• Cord restraint @
- hook the loop in the extension cord over restraint P
as illustrated
- pull tight to secure the extension cord
• On/off #
- switch on tool by first pressing safety switch Q and
then pulling trigger switch R
- switch off the tool by releasing trigger R
! do not stop chain saw after sawing by activating
front hand guard S 2 (= kickback brake)
• Kickback brake $
The kickback brake is a safety mechanism activated
through front hand guard S, when kickback occurs ->
chain stops immediately
The following function check should be carried out at
regular intervals:
- push front hand guard S forward and start the
chain saw -> the chain must not start
- to deactivate the kickback brake, release trigger
switch R and pull hand guard S backwards
• Operating the tool %
- always hold the chain saw firmly with both hands
(front handle T with the left hand and rear handle U
with the right hand); never operate chain saw using
only one hand %a
- ensure power cord is located to the rear, away from
the chain and wood and so postioned that it will not
be caught on branches or the like during cutting
! the chain must be running at full speed before
it makes contact with the wood
- use metal gripping teeth V to secure the saw onto
the wood before starting to cut %a
- use the gripping teeth as a leverage point "✱" while
cutting %a
- reset the gripping teeth at a lower point when sawing
thicker logs by pulling the chain saw slightly
backwards until the gripping teeth release, and
reposition at a lower level to continue sawing; do not
remove the saw completely from the wood
- do not force the chain while cutting; let the chain do
the work, using gripping teeth V to apply minimum
leverage pressure
- use the chain saw only with secure footing
- hold the chain saw at the right-hand side of your body %b
- do not operate the chain saw with arms fully extended
or attempt to saw areas which are difficult to reach, or
on a ladder %c
- never use the chain saw above shoulder height %d
- sawing is optimized when the chain speed remains
steady during cutting
! beware when reaching the end of the cut; the
weight of the saw may change unexpectedly as it
cuts free from the wood (accidents may occur to
legs and feet)
! always remove the saw from a wood cut while the
saw is running
• Cutting logs
- support logs so that the face sides at the cut do not
close in against each other, which would result in the
chain being jammed or pinched
- position and set short logs safely prior to sawing
- when sawing, always take care to avoid hitting stones,
nails, etc., as these could be thrown up or cause damage
to the chain or serious injury to the operator or bystanders
! keep a running chain clear of wire fencing or
the ground
- length cuts must be carried out with care, as leverage
with gripping teeth V 2 is not possible; saw at a flat
angle to avoid kickback
- there is a high risk of accidents when sawing wood,
branch or trees under tension; be extremely careful
(leave saw jobs like these to professionalsl)
• Bucking a log (cutting a log into lengths)
- when possible, the log should be raised and supported
by the use of limbs, logs or chocks
- it is important to make sure your footing is firm and
your weight is evenly distributed on both feet
- when the log is supported along its entire length as
illustrated, it is cut from the top (overbuck) ^a
- when the log is supported on one end as illustrated,
cut 1/3 the diameter from the underside (underbuck);
then make the finished cut by overbucking to meet the
first cut ^b
- when the log is supported on both ends as illustrated,
cut 1/3 the diameter from the top (overbuck); then
make the finished cut by underbucking the lower 2/3 to
meet the first cut ^c
- when bucking on a slope always stand on the uphill
side of the log
- when "cutting through", to maintain complete control
release the cutting pressure near the end of the cut
without relaxing your grip on the chain saw handles.
! do not let the chain contact the ground
- after completing the cut, wait for the saw chain to stop
before you move the chain saw
- always stop the motor before moving from tree to tree
