4. Intended use

The chainsaw with telescoping arm is intended for
removing branches from trees. It is not suitable for ex-
tensive sawing work and felling trees or for the sawing
of materials other than wood. Please observe that our
machine was not designed for use in commercial, techni-
cal or industrial applications. We assume no liability if the
machine is used in commercial, technical or industrial
applications or for equivalent activities.

5. Assembly

Attention! Only connect the chainsaw to the mains
supply once it has been completely assembled and
the chain tension has been set. Always wear protective
gloves when carrying out work on the chainsaw in order
to prevent injury.
5.1 Assembly of guide bar and saw chain
Carefully unpack and inspect all parts for completeness.
(Fig.1)
• Loosen the fastening bolt for the chain sprocket cover.
(Fig.2)
• Remove the chain sprocket cover.
• Place the chain in the groove of the guide bar as
shown. (Fig.3/Pos. A)
• Insert the guide bar and chain into the mount on the
chainsaw. (Fig. 4) In the process, guide the chain
around the pinion and hang the guide bar in the chain
tensioning bolts.
• Re-mount and hand-tighten the chain sprocket cover
with the fastening bolt. (Fig.5)
Attention! Only tighten the fastening bolt once the
chain tension has been adjusted (see 5.2).

5.2 Tensioning the saw chain

• Loosen the fastening bolt of the chain sprocket cover
• Adjust the chain tension with a screwdriver at the

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
Filling the oil tank (Fig. 8)
• Place the chain saw on a level surface.
• Clean the area around the oil tank cap (Pos.10) and
• Fill the oil tank with saw chain oil. In doing so, make
• Close the oil tank cap (Pos.10).

clockwise rotation reduces the chain tension. The saw
chain is correctly tensioned if it can be raised approx.
2 mm in the centre of the guide bar. (Fig.6 + 7)
Attention! All chain links must lie properly in the
guide groove of the guide bar.
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.
