Checking the chain lubrication
Check the chain lubrication as follows: Start the chainsaw and hold the bar roughly 20 cm above a tree stump
or other light background. If the lubrication system is working properly, some oil will fly off the chain and show
up on the light object. If no traces of oil appear, you should clean the outlet hole (C) and the upper hole (B)
in the guide bar (fig. 6 ), or contact your retailer or service centre. Be careful not to let the saw chain come in
contact with the ground.
Chain oil
The useful life of the guide bar and saw chain depend on which chain oil is used. Use only chain oil and never
waste oil, etc. Use environmentally friendly oil and keep it in a sealed container specially reserved for chain oil.
3.6 Guide bar
The guide bar (7) wears out more at the nose and along the bottom edge, turn the bar over when you remove it
to sharpen the chain so that it wears evenly on both edges. File off any unevenness in the bar using a flat file.
Sprocket
The sprocket (14) also becomes worn, check it regularly for signs of wear or deformity and change it if
necessary. A worn sprocket will wear out a new saw chain more quickly. Contact your retailer or service centre
for replacement sprockets.
Blade cover
Put the blade cover on the blade as soon as you have finished sawing and whenever storing or
transporting the saw.
3.7 Kickback guard/chain brake
In the event of kickback, the chain brake wil be activated by the front handle guard (5) being pushed forward by
your hand. The chain will stop immediately (fig. 11).
Testing the kickback guard
Warning!
Always check the chain brake before using the chainsaw.
Hold the chainsaw firmly in both hands,
start it and push the kickback guard
forward (towards “0”) with your wrist.
The saw chain should stop immediately.
Resetting the kickback guard/chain brake
The chain brake must be reset before the saw can be started again: Switch off the chainsaw (release the power
switch), push the kickback guard (5) back until it returns to the upright position
I
(fig. 11), the kickback guard is
now reset.
