Checking the chain brake
NOTE:
If the chain saw fails to start, the chain brake must
•
be released. Pull the hand guard backwards firmly
until you feel it engage.
Hold the chain saw with both hands when switching it
on. Hold the rear handle with your right hand, the front
handle with your left. The bar and the chain must not be
in contact with any object.
First press the lock-off button, then the switch trigger.
The saw chain starts immediately.
Press the hand guard forwards using the back of your
hand. The saw chain must come to an immediate

Check the oil delivery as follows:
Start the chain saw.
With the saw running, hold the saw chain approximately
15 cm above a tree trunk or the ground. If lubrication is
adequate, the oil spray will produce a light oil trace.
Observe the wind direction, and do not expose yourself
to the oil spray unnecessarily.
CAUTION:
If an oil trace is not formed, do not use the saw.
•
The lifespan of the chain will otherwise be reduced.
Check the oil level. Clean the oil feed groove and
the oil feed
"MAINTENANCE ").
WORKING WITH THE CHAIN SAW

For bucking cuts, rest the serrated rail shown in the
figure on the wood to be cut.
With the saw chain running, saw into the wood, using
the rear handle to raise the saw and the front one to
guide it. Use the serrated rail as a pivot.
Continue the cut by applying slight pressure to the front
handle, easing the saw back slightly. Move the serrated
rail further down the timber and raise the front handle
again.
When making several cuts, switch the chain saw off
between cuts.
CAUTION:
If the upper edge of the bar is used for cutting, the
•
chain saw may be deflected in your direction if the
chain becomes trapped. For this reason, cut with
the lower edge, so that the saw will be deflected
away from your body.
