6. ASSEMBLY
Attention! Do not connect the chainsaw to the
mains until it is completely assembled and the
chain tension is adjusted. In order to avoid
injury, always wear protective gloves when
working on the chainsaw.
6.1 Assembly of saw bar and saw chain
Carefully unpack all parts and check them for
completeness. (B1)
- Loosen the fixation screw for the sprocket cover.
(B2)
- Remove the sprocket cover.
- Insert the chain in the circumferential groove
(B3/pos. A) of the saw bar (see illustration).
- Insert saw bar and chain in the support of the
chain saw (B4). Lay the chain around the pinion
and hook the saw bar in the chain tension rod.
- Attach the sprocket cover and tighten it by
hand using the retaining screw.
Attention! Do not fully tighten the retaining
screw until the chain tension is adjusted.
6.2 Tensioning the saw chain
Attention! Always disconnect the power tool
from the mains before inspection and adjustment
work. Always wear protective gloves when
working with the chainsaw in order to avoid
injury.

- Loosen the retaining screw of the sprocket
cover by a few turns. (B2)
- Adjust chain tension with the chain-tensioning
screw using a screwdriver. (B5)
- Turning the screw to the right will increase chain
tension, while turns to the left will reduce it. The
saw chain is adequately tensioned if it is possible
to lift the chain in the centre of the saw bar by
approx. 2mm. (B6)
Attention! All chain links must be correctly
inserted in the guiding groove of the chain
bar.
Instructions for chain tensioning:
The saw chain must be correctly tensioned
in order to guarantee safe operation. It is
adequately tensioned if it is possible to lift the
chain in the centre of the saw bar by approx.
2mm. As the saw chain heats up during cutting
and thus changes its length, you must check
the chain tension at least every 10 minutes and
adjust it, if necessary. This especially applies for
new saw chains. Release tension from the saw
chain after you have finished your work, as it will
shorten when cooling down. In this way, you can
avoid damage to the chain.
6.3. Saw chain lubrication
Attention! Always disconnect the power
tool from the mains before inspection and
adjustment work. In order to avoid injury,
always wear protective gloves when working
with the chainsaw.
Attention! Never use chains without saw chain
lubrication! Using the chain saw without saw
chain oil or with an oil level below minimum
will result in damage to the chainsaw!
Attention! Observe temperature conditions:
Lubricants with very different viscosities are
required for different ambient temperatures.
