it could lead to death or serious bodily
injury. Electricity can jump from one point to
another by arcing. The higher the voltage,
the greater the distance electricity can jump.
Electricity can also travel through branches
and other objects, especially if they are
wet. Always keep a distance of at least 10
m between the product and high-voltage
power lines and/or any objects that are
touching them. If have to work within this
safe distance you should always contact the
relevant power company to make sure the
power is switched off before you start work.
WARNING:
reach. Make sure that no people or animals
come closer than 15 m when the product is
running.
WARNING:
trigger without having the cutting attachment
in full view.
•
Hold the product as close to your body as possible to
get the best balance.
•
Make sure that the tip does not touch the ground.
•
Do not rush the work, but work steadily until all the
branches have been cut back cleanly.
•
Release the power trigger after each working
operation. Long periods at full speed without any
load on the motor can cause serious motor damage.
Introduction
Below you will find some general maintenance
instructions. If you need further information please
contact your service workshop.
To perform maintenance on the
attachment
To check the saw chain
Do a check of the saw chain daily.
1. Make sure that there are no cracks in rivets and
links. (Fig. 38)
2. Examine if the saw chain is rigid.
3. Compare the saw chain with a new saw chain to
examine if the rivets and links are worn.
4. Replace the saw chain if it exhibits any of the
conditions above.
5. Replace the saw chain when the length of the cutting
teeth has worn down to only 4 mm (0.16 in.) (Fig. 39)

Maintenance
•
Always work at full speed.
•
Observe great care when working close to overhead
power lines. Falling branches can result in short-
circuiting.
•
Whenever possible position yourself so that you can
make the cut at right angles to the branch. (Fig. 32)
•
Do not work with the shaft held straight out in front of
you (like a fishing rod) as this increases the apparent
weight of the cutting attachment. (Fig. 33)
•
Cut large branches in sections so that you have
better control over where they fall. (Fig. 34)
•
Never cut through the swelling at the root of the
branch as this will slow down healing and increase
the risk of fungal attack. (Fig. 35)
•
Use the stop at the base of the cutting head to
provide support during cutting. This will help prevent
the cutting attachment from "jumping" on the branch.
(Fig. 36)
•
Make an initial cut on the underside of the branch
before cutting through the branch. This will prevent
tearing of the bark, which could lead to slow healing
and cause permanent damage to the tree. The
cut should not be deeper than 1/3 of the branch
thickness to prevent jamming. Keep the chain
running while you withdraw the cutting attachment
from the branch to prevent it jamming. (Fig. 37)
•
Use the harness to support the weight of the
machine and make it easier to handle.
•
Make sure you have a firm footing and that you can
work without being hampered by branches, stones
and trees.
To do a check of the drive sprocket
•
Regularly examine if the drive sprocket is worn.
Replace the drive sprocket if it is necessary. (Fig.
40)
To do a check of the guide bar
1. Make sure that the oil channel is not blocked. Clean
the oil channel if it is necessary. (Fig. 41)
2. Examine if there are burrs on the edges of the guide
bar. Use a file to remove the burrs. (Fig. 42)
3. Clean the groove in the guide bar. (Fig. 43)
4. Examine if the groove in the guide bar is worn.
Replace the guide bar if it is necessary. (Fig. 44)
5. Examine if the guide bar tip is rough or very worn.
(Fig. 45)
6. Make sure that the bar tip sprocket turns freely and
that the lubrication hole in the bar tip sprocket is not
blocked. Clean and lubricate the bar tip sprocket if it
is necessary. (Fig. 46)
7. Turn the guide bar daily to extend its life cycle. (Fig.
47)
