Working with the machine

Before starting work, always check that the
machine is in perfect working order. The
following are particularly important:
- Guide rail and chain fitted correctly
- Sawing chain has the correct tension,
- Chain lubrication works
- Never work with a blunt or worn sawing chain.
- Check that the device is correctly attached to the
cordless multifunction drive.
- Only use the machine when undamaged and
complete.
There is the risk to be hit by falling branches.
Always keep sufficient distance to the branch
you are sawing off.
Avoid abnormal postures and never cut above
shoulder height.
Practice all work techniques. Inexperienced
persons are strongly advised to seek
competent advise and guidance from an
experienced person before operating this machine.
Basic working method, sawing through
branches and twigs
Choose your location so that will not get hit by the
falling branch.
Hold the machine at an angle so that the angle
between the rod (1) and ground is a maximum of
60°.
Start sawing on branches at the bottom so that the
branches above have room to fall down.
Saw off long branches in several steps.
In order to avoid tearing off the bark: Do not make
the final cut until you have sawn off most of the
branch, thus reducing the weight.
Pull the machine out of the wood only with the
sawing chain running.
Do not work close to the ground. The guide rail must
not touch the ground because this would cause the
sawing chain to become blunt very quickly.
1. Press the machine with the stop (9) against the
wood. The chain must not touch the wood when
it is switched on. Switch on the machine and only
then start sawing by guiding the saw
downwards. Do not press, the saw's own weight
is sufficient. Towards the end of the cut, take the
weight off the saw. Prepare yourself for the
weight of the saw that you will have to support
when the saw has cut through the branch.
2. To maintain full control of the machine at the
actual "cut-through" point, reduce the acting
weight force of the saw without loosening your
firm hold on the machine handles.

3. After completing the cut, switch off the motor,
wait for the sawing chain to come to a stop
before removing the machine. Always switch off
the machine before moving from branch to
branch.
Never attempt to free a jammed saw with the
motor running. Switch off the motor and
remove battery packs. If the branch can be reached
from the ground, hold the saw firmly and lift the
branch. If the saw is still stuck, seek professional
help.
Do not use the saw as a lever.
Retensioning the sawing chain
When working with the machine, the sawing chain
expands as a result of heat. It then starts to sag and
can jump out of the guide rail groove.
Check the chain tension (as specified in chapter
6.1) and retighten the sawing chain if necessary.
If the sawing chain is retensioned when it is hot, at
the end or work it must be slackened because
otherwise cooling could result in high contraction
tension.
Insufficient chain lubrication
If the oil reservoir is still almost full after machine
operation of around 3- 5 minutes, it may be that the
oil channel (15) of the machine, or the oil inlet bore
(14) of the guide rail, is obstructed and has to be
cleaned.
8. Transporting
Remove the battery packs, allow the machine to
come to a standstill. Slide the protective cover (6)
onto the guide rail (7).
Secure the machine during transport to prevent oil
loss, damage or injury.
9. Cleaning
Remove the battery packs, allow the machine to
come to a standstill. Clean after each use: Remove
contamination, wood shavings etc. (e.g. with a
brush or cloth).
10. Storage
Remove the battery packs, allow the machine to
come to a standstill. Slide the protective cover (6)
onto the guide rail (7).
Clean and maintain the machine before storage.
Store in a secure, dry place out of the reach of
children.
11. Maintenance
WARNING! Remove the battery packs .
Unintentional start-up can cause serious
injuries. The machine must be stationary. Wear
protective gloves.
Carefully maintain machine tools and accessories.
Check for misalignment or binding of moving parts,
breakage of parts and any other condition that may
