chain cannot be fixed on the guide rail. It is there-
fore best to remove the chain from the rail and then
sharpen it.
• Select a sharpening tool that is suitable for the
chain pitch.
The chain pitch (e.g. 3/8") is marked in the depth
gauge of each knife.
Only use files specifically for saw chains!
Other files have the wrong shape and the wrong edge.
Select the diameter of the file according to your chain
pitch. Be sure to also note the following angles when
sharpening the chain blades.
A = file angle
B = angle of the side plate
Furthermore, the angle must be maintained for all
blades.
If the angles are uneven, the chain will run erratically,
wear out quickly and break prematurely.
Since these requirements can only be met with suffi-
cient and regular practice:
• Use a file holder
A file holder must be used when sharpening the saw
chain by hand. The correct filing angles are marked
on it.
• Hold the file horizontally (at the correct angle to the
guide rail) and file according to the angle marking
on the file holder. Support the file holder on the top
plate and the depth gauge.
• Always file the blade from the inside out.
• The file only sharpens as it moves forward. Lift the
file off as you move backwards.
• Do not touch the fastening straps or dynamic links
with the file.
• Turn the file regularly to avoid wear on one side.
• Use a piece of hard wood to remove the burr from
cut edges.
All blades must have the same length, otherwise they
will also be of different heights.
This causes the chain to run erratically and increases
the risk of breaking.
Lubricate the drive, pole-mounted pruner
Lubricate the drive every 10 to 20 operating hours.
1. Apply the grease gun to the grease nipple Fig .54 (Q).
2. Squeeze some grease into it.
Attention! Top up with only a little grease. Under no cir-
cumstances overfill.
Check the hedge trimmer for obvious defects such as:
• loose fastenings.
• worn or damaged components.
• bent, broken or damaged cutting device.
• covers or protective devices correctly mounted and
intact.
• Wear, especially sliding clearance of the cutting
device.
Replace damaged or blunt cutting tools immedi-
ately, even if only slightly damaged.
Lubricate transmission, hedge trimmer
Lubricate the drive every 10 to 20 operating hours.
1. Apply the grease gun to the grease nipple Fig .48 (P).
2. Squeeze some grease into it.
Attention! Top up with only a little grease. Under no cir-
cumstances overfill.
Oil the cutting device and the angle adjustment with
environmentally friendly lubricating oil.
Adjusting the idle speed Fig. 62
If the cutting device continues to run when idle, the idle
speed must be corrected.
1. Allow the engine to run for 3-5 minutes
(Not at high speed!)
2. Turn the set screw (S):
Clockwise
-- Idle speed increases (+)
Counter clockwise
-- Idle speed decreases (-)
The idle speed is 3000
Contact the manufacturer if the cutting device still
continues to run with the engine at idle. Do not
continue to work with the device under any cir-
cumstances!
