5. Assembly
Attention! Only connect the chainsaw to the power sup-
ply when it is fully assembled and the chain tension has
been adjusted. Always wear work gloves when you are
working on the chainsaw, to avoid injuries.
5.1 Installing the bar and saw chain (fig. 2 - 5)
Carefully unpack all parts and check these for complete-
ness. (fig.1)
Attention! Danger of injury. Wear safety gloves
when fitting the chain.
• Place the chainsaw on a stable surface.
• Turn the thumb screw (18) anticlockwise , the chain
wheel cover (9) (see fig. 2).
• Lay the saw chain (12) on the bar (13) and note the
running direction of the chain. The cutting teeth
must be on the top of the bar and facing forwards
(see fig. 3).
• Lay the free end of the saw chain over the chain drive
wheel (see fig. 4 B) and the bar (13) with the elongat -
ed hole over the bar guide (C).
• Install the chain wheel cover (9) and turn the thumb
screw (18) a little in a clockwise direction , to fix the
cover hand-tight (fig. 2).
• Make sure that the chain tensioning bolt (E) (fig. 5)
sits precisely in the small opening in the bar (see
fig. 4, D).
• Then use the SDS chain tension ring (19) to set the
correct chain tension (see following section).
5.2 Tensioning the saw chain (fig. 6 and 7)
Attention! Always unplug the mains plug before
inspection and adjustment work. Always wear
work gloves when you are working on the chain-
saw, to avoid injuries.
a) Dir : Tighten chain
b) Direction - : Loosen chain
If the device is equipped with SDS, this means that you
can loosen or tighten the chain and the bar (guide plate)
without having to use a tool. You can adjust the chain
tension using the chain tension ring (19) on the SDS. You
can use the thumb screw (18) on the SDS to loosen or
tighten the bar.
Unscrew the thumb screw (18) a little in an anticlockwise
direction . Then use the SDS outer ring (19) to set the
correct chain tension (loosen- / t) (fig. 6). Con -
tinue to tension the chain until it can be lifted by around
2 mm in the middle of the bar as shown in fig. 7. Now
tighten the thumb screw (18) completely .
Attention: During the run-in time, the chain
must be re-tightened frequently. Immediately
re-tighten the chain if it flutters or hangs out
of the groove!
Information regarding the tensioning of the chain
The saw chain must be tensioned properly in order to
ensure safe operation. The chain tension is optimal if the
saw chain can be lifted 2 mm in the centre of the guide
bar. Since the saw chain heats up during the sawing
process, whereby its length changes, you must check
the chain tension at least once every 10 min. and adjust
it as necessary. This applies in particular for new saw
chains. Slacken the saw chain after work is completed,
because it shortens when cooling down. In doing so,
you can prevent damage to the chain.
5.3 Saw chain lubrication
Attention! Always pull out the mains plug before
inspection and adjustment work. Always wear
protective gloves when carrying out work on the
chainsaw in order to prevent injury.
Attention!
Never operate the chain without saw
chain oil! The use of the chainsaw without saw
chain oil or with an oil level below the minimum
oil level mark results in damage to the chainsaw!
Attention! Only use special chainsaw oil. The war-
ranty is voided with the use of used oil.
Filling the oil tank (Fig. 8 and 9)
• Place the chain saw on a level surface.
• Clean the area around the oil tank cap (Pos.10) and
then open it.
• Fill the oil tank with saw chain oil. In doing so, make
sure that no dirt gets into the oil tank so that the oil
nozzle does not clog.
• Close the oil tank cap (Pos.10).
• Before starting work, check the chain lubrication
function. Switch on the saw with cutting attachment
fitted, and maintain sufficient distance above a light
background (caution, no contact with the floor!).
If traces of oil appear, chain lubrication is working
properly (fig. 9).
