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:
• A File Holder must be used when sharpening the saw
chain by hand. The correct filing angle marked on it.
• Hold the file horizontally (at a right angle to the guide rail)
and file according to the angle mark on the file holder.
Support the file holder on the top plate and depth gauge.
• File down. The knife is always from the inside to the
outside

• The file sharpens only in forward motion. Lift it off in the
backward motion.
• Do not touch the dynamic links with the file.
• Turn the file regularly continue to avoid a onesided wear.
• Remove to remove a piece of hard wood, bones raw
edges.
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.
Oiling the gears (pole saw)
Oil the gears every 10 to 20 operating hours.
1 Position the grease gun at the lubricating nipples
Fig.54(Q).
2 Insert some grease.
Attention! Fill only a small amount of grease. Do not
overfill.
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
devices
– wear, in particular, cutting tool play
Immediately replace damaged or blunt cutting tools,
even in the event of minor damage.
Oiling the gears (hedge trimmer)
Oil the gears every 10 to 20 operating hours.
1 Position the grease gun at the lubricating nipples
Fig.48(P).
2 Insert some grease.
Attention! Fill only a small amount of grease. Do not
overfill.
Oil the cutting tools and the angle adjustment with
environmentally friendly lubricant.
Adjusting the idle speed Fig. 62
If the cutting device runs idle, correct the idle speed.
1. Allow the engine to warm for 3-5 minutes
(No high speeds!).
2. Turn the adjusting screw (S): clockwise
- idle speed increases (+)
counterclockwise
- Idling speed decreases (-)
The idle speed is 3000 min-1
Contact the manufacturer if the cutter continues to run
at idle.
Do not continue to operate the unit!
The user is responsible for all damages caused by
non-compliance with instructions in this manual.
This also applies to non-authorized modifications
of the tool, use of non-authorized spare parts,
accessories, working tools, unrelated and not
intended use, secondary damages due to use of
faulty components.
