Care of the guide rail
Turn the rail around every time you have the chain
sharpened or replaced. This will avoid a one-sided wear
of the rail, especially at the top and bottom.
Regularly clean

Servicing and sharpening of saw chain
The correct sharpened chain
Working effectively with the chainsaw is only possible if
the chain is in good condition and
sharp. This also reduces the risk of kickback. The chain
can be re-sharpened by any dealer. Do not attempt
to sharpen the chain yourself unless you have the
necessary special tools and experience. A properly
sharpened chain goes way through the wood and it
requires very little pressure. Do not work with a dull or
damaged chain. It increases physical exertion, increase
the vibrations and leads to unsatisfactory results and
higher wear.
• Clean the chain.
• Check it.
• Replace damaged or worn parts with matching spare
parts they are in the shape and size of the original
parts as necessary.
• Sharpening a chain should be performed only by
experienced users!
Notice. Below the angle and dimensions If the chain
is not properly sharpened or the depth is too small,
there is a higher risk of reversion effects and resulting
injuries! The chain cannot be fixed on the guide rail. It
is therefore best to remove the chain from the rail and
then sharpen.
• Select the appropriate tools for the chain pitch
sharpening tool. See "Specifications" for the allowed
chain pitches.
The chain pitch (for example 3/8 ") is highlighted in the
depth of each blade. Use only special files for chainsaws!
Other files have the wrong shape and the wrong cut.
Select the file according to the diameter of your chain
pitch. Make sure to observe the following angle when
sharpening the chain diameter.

A = filing angle
B = the angle of the side plate

The angle must also be maintained for all knives.
For irregular angles, the chain is run irregularly, wear
quickly and break down prematurely.
Since these requirements can only be met with sufficient
and regular exercise:

• Remove to remove a piece of hard wood, bones raw
All knives must have the same length, otherwise they
will also vary. As a result, the chain is irregular and it
increases the risk of going broke.
Check the hedge trimmer for obvious faults such as:
– loose attachments
– worn or damaged components
– bent, broken or damaged cutting tools
– correctly attached and working covers and safety
– wear, in particular, cutting tool play
Immediately replace damaged or blunt cutting tools,
even in the event of minor damage.
Oiling the gears
Oil the gears every 10 to 20 operating hours.
1 Position the grease gun at the lubricating nipples (10).
2 Insert some grease.
Oil the cutting tools and the angle adjustment with
environmentally friendly lubricant.
Setting the idle speed Fig. 50
If the cutting tool is still moving when the device is in idle,
change the idle speed.
1. Let the motor warm up for 3-5 minutes
