7. Attachment and operation

Warning!
Always wear safety goggles, ear muffs, protective
gloves and heavy-duty work clothes!
Use the saw only with approved extension cables with
the prescribed insulation and connections designed for
outdoor use (approved rubber-sheathed cables) which
fit the chainsaw plug.
The chain saw is equipped with safety switches, requi-
ring the use of both hand. The chainsaw works only
when one hand is pushing the button 11 and 13 at the
same time. If the chainsaw does not run, the chain bra-
ke must be released at the front finger guard (3). Be
sure to read the sections "Chain brake" and " Releasing
the chain brake " on this point.
To switch on:
• Release the chain brake (3), push in the lock (11) and
press the power switch (13).
• Place the lowest claw (Fig 2, J) on the wood . Raise
the chain saw by the rear grip (1 ) and saw into the
wood. Move the chain saw back a little and place the
claw further down.
• Be careful when sawing splintered wood as pieces of
wood may be ripped off.
After switching on, the chainsaw will run immediate-
ly at high speed .
To switch off
• Release either the ON/OFF switch (13) on the rear
grip.
• The release of ON/OFF switch results the stop of the
chainsaw within 1sec., and heavy sparkling.
This is normal and safe for the proper operation of the
chainsaw.
• After working with the chainsaw, you should always:
Clean the saw chain and guide bar and replace the
chain guard.
• If the chain brake is activated the chainsam will be
deactivated immediately

8. Initial operation

The voltage and current supply must comply with the
ratings on the type plate.
Before commencing work, always check that the chain-
saw works properly and is safe to operate.
Check also that the chain lubrication and the oil gauge
are in good working order (see Fig.4). When the oil lever
is approx. 5 mm from the bottom mark, you must top
up with oil. When the oil level is higher you can work
without worry.
• Switch on the chain saw and hold it above the ground.
Be careful not allow the chainsaw to touch the ground.
For safety reasons it is best to keep a clearance of at
least 20 cm. If you now see growing traces of oil, the
chain lubrication system is working correctly. If there
are no traces of oil at all, try cleaning the oil outlet (Fig
2, C), the upper chain tensioning borehole (Fig 3, e)
and the oil duct, or contact your Customer Service.
(Be sure to read the section "Filling in chain oil and
chain lubrication" on this point).
• Check the chain tension and retention, if necessary
(see the section "Tensioning the saw chain" on this
point).
• Make sure the chain brake is working properly (see
also the section "Releasing the chain brake").
Assembly
Fitting the guide bar and chain (Fig 1, 2, 3)
If the chain saw is already connected to the power sup-
ply: Pull the plug from the socket outlet. Wear protective
gloves whenever doing any work on the saw chain.
Important: The front finger guard (3) must always be in
the top (vertical) position (Fig. 5).
The guide bar and saw chain are supplied separately.
To assemble, first unscrew the lock nut (SDS-system/5)
and remove the guide bar cover (6). The guide bolt (17)
must be in the centre of the guide.
If necessary, adjust the chain tensioning with the chain
wheel (Fig.3, 5a).
To prevent injury on the sharp cutting edges, always
wear gloves when assembling, tensioning and checking
the chain.
Before assembling the guide bar with the saw chain,
check the cutting direction of the teeth!
The running direction is marked with an arrow on the
cover (6). To determine the direction of cut, it may be
necessary to turn over the saw chain (4).
Hold the guide bar (7) vertically with the tip pointing
upwards and put on the saw chain (4, beginning at the
tip of the bar.
Then assemble the guide bar with the saw chain as
follows:
• Place the guide bar with the saw chain on the chain
wheel (16) and guide bolt (17). Ensure that the
adjustment plate (Fig.3/7A) is showing to you.
• Place the saw chain round the chain wheel (16).
Cause the chainsaw to the sprocket and check
whether it is correctly.
• Place the cover (6) on top and tighten gently with
the lock nut (5).
Now the saw chain has to be correctly tensioned.
Tensioning the saw chain
Always pull the plug out of the power socket before
doing any work on the chainsaw!
Wear safety gloves!
Make sure the saw chain (4) is inside the guide groove
of the guide bar (7).
Turn the outer Knob (Fig. 3/5A) clockwise until the saw
chain is correctly tensioned, then rotate the inside knob
(5) to block the guide bar in that position.
While the inside knob is being tightened, the guide bar
must then be pushed upwards.
Check the chain tension again. Do not tension the chain
too tightly.
When cold, it should be possible to lift the chain in the
middle of the guide bar approx. 5 mm. Tighten the lock
nut (5) securely.
When warm, the saw chain will expand and slacken and
there is a danger of it jumping off the rail altogether. Re-
tension if necessary.
If the saw chain is re-tensioned when hot, it must be
loosened again when the sawing work has been com-
pleted.
