4. Grinding/filing the saw chain
When the saw chain becomes blunt, it no longer cuts safely and efficiently and must be replaced or sharpened.
Note:
It is easiest to file the chain with the help of a file gauge which you can buy from a trade supplies store.
The file gauge will come with instructions for its use.
File the chain as follows:
• Unplug the chainsaw from the wall socket.
• Wear gloves to protect your hands.
• Check the chain tension.
• Push the chain brake forward to lock the chain in the same position on the guide bar.
• Use a 4 mm diameter round file.
• File horizontally across the guide bar at an angle of 38˚ to the chain’s direction of rotation.
• File each tooth outwards/forwards in the chain’s direction of rotation.
• File each tooth with the same number of
strokes, so that the chain is evenly filed.
• Check the height of the rakers every 5th
time you file the chain, if the rakers need
filing, use a flat file. It is important that their
original shape is not altered.
• Measure the height (depth setting) of
the rakers after filing using a guide that can
be bought at a trade supplies store.

5. Starting to use the chainsaw
Always wear safety glasses/visor, ear muffs, safety gloves and protective clothing which is specially
designed for chain saw work.
Use only extension leads intended for outdoor use and which have sufficient core area (at least 1.5 mm², max
75 m long). The chainsaw is equipped with a safety switch: The power trigger (3) and lockout button (2) on
the rear handle (1) must both be pressed in simultaneously in order for the chainsaw to start. The chainsaw must
be held firmly in both hands when it is started.
If the chainsaw does not start, reset the kickback guard/chain brake: Return the kickback guard (5) to
the upright position. Refer to
Resetting the kickback guard/chain brake
(fig. 11). The chainsaw should
now start straight away on full speed.
How to switch the chainsaw off:
Release the power trigger (13)
and safety lockout button (11)
and the chainsaw will stop after
1 second. Vibrations can occur,
this is normal and nothing to
worry about.
After finishing work: Always
clean the saw chain and guide
bar then put the cover on
the guide bar.
