Safety Notes
The garden tool may only be used by one person at a time.
Make sure bystanders or animals are not in the garden tool’s
area of swing.
Make sure the garden tool is not touching anything and moving
free when starting the engine. Keep all parts of your body away
from the cutting attachments while the engine is running. Keep
the handles dry, clean and free of oil.
Use only original accessories and original replacement parts.
Use extreme caution when cutting small size brushes and
saplings because flexible material can be jammed in the saw
chain and whipped towards your body to cause injuries or pull
you off balance.
Do not modify the electric garden tool in any way.
Do not carry the garden tool with the attachments facing forward.
Protect the electric garden tool from moisture.
Should the electric garden tool become damaged do not use it

of H07RN-F; 3x1.5 mm2. Ask your electrician.
For using the gardening tool, we recommend the use of an RCD
with a residual current < 30 mA. In Switzerland the utilisation of
an RCD is obligatory.
Safety Precautions against Kickback and Pushback
Always keep the saw chain sharp. This will ensure a high level of
safety against kickback and throwback. Removal of any safety
devices, inadequate maintenance or incorrect mounting of the guide
bar and saw chain will increase the safety risk and lead to serious
injuries due to kickback.
For safety reasons do not use any other saw chain or guide bar
types not specified in this manual.
Kickback is the upward motion of the guide bar that occurs when
the saw chain tip contacts a hard object. Kickback is dangerous
and can lead to loss of control of the device.
Before cutting logs, secured in position. When working on
sloping ground, make sure to work facing upwards.
Personal Safety Equipment
When working with the electric garden tool, wear eye protection,
protective gloves and hearing protection. Wear cut-proof and
tight-fitting clothes and safety boots. When working with the saw
wear protective head gear.
Even in case of appropriate use of the chain saw some risk
remains. Potential human health hazards can be:
Cuts due to contact with an unprotected saw chain or when
touching a moving saw chain or the cutter bar of the hedge
trimmer. The cutting string of the string trimmer or the brush
cutter knife can also result in severe cuts.
Abrasions caused by to parts that are thrown off the saw chain
or from the cut material.

Preparation
Mounting the Auxiliary Handle
It is not allowed to operate the garden
tool without mounting the auxiliary
handle (11)!
Mount the auxiliary handle by using the
included screws onto the shaft of the
motor unit, as shown in the picture on
the right.
Mounting the Shoulder Strap
Always use the shoulder strap (17) when operating the garden tool.
Switch off the garden tool before removing the shoulder strap.
Attention! There is risk of injury.
1. Mount the karabiner hook of
the shoulder strap on the
shoulder strap lug (12) of the
garden tool.
2. Adjust the length of the strap.
The karabiner hook should be
situated at the level of the hip.
Before mounting any of the attachments, familiarize yourself how
to start the motor unit!
Switching ON and OFF the Motor Unit
1. Insert the power plug into the socket.
2. First push the safety switch (13) with your thumb forwards and then
depress the ON/OFF switch (14) in order to switch on the garden
tool.

Mounting
1. Depress the safety pin and insert the pole pruner attachment onto
the motor unit.
2. Make sure the safety pin engages securely into the provided
opening. You will hear a click sound.
3. Tighten the pole pruner attachment by using the screw cap (10).
Mounting the Guide Bar and the Saw Chain
Always wear protective gloves when mounting the saw chain (3). The
saw chain is sharp! When working on the saw chain pull the power
plug. There is risk of injury!
1. Attach the saw chain
(3) onto the guide
bar (4). Place the
saw chain with the
guides engaged in
the slot of the guide
bar.

11
Pole Pruner
2. Guide the chain over the
drive sprocket. The chain
tensioning device must lock
into the corresponding hole
in the guide bar.
3. Attach the plastic cover (8)
and slightly tighten die
retaining nut.
4. Use the tensioning screw to
tighten the saw chain. After
that, tighten the retaining
nut.
Tensioning the Saw Chain
1. For tightening the saw
chain, turn the retaining nut
clockwise.
2. For loosening the tension,
turn the retaining nut
counter clockwise.
Hints:
Only use sharp chains. Dull chains can easily get jammed. While
working with new chains, regularly check the chain tension because
new chains can lengthen considerably upon initial operation.
The service life of a saw chain mainly depends on sufficient
lubrication and correct tensioning.
During operation, the saw chain heats up, and tensioning may be
necessary. Slacken the chain after use so it will not be too tight
after cooling down.
Do not tension an overheated chain. After cooling down, the chain
may shorten and become over tensioned. Before tensioning the
saw chain, wait until it has cooled down.

12
Pole Pruner
The tension of the saw chain is important for your safety and for the
function of the equipment. A correctly tensioned saw chain increas-
es the durability of your gardening tool.
Check the chain tension before each use of the gardening tool.
The saw chain is correctly tensioned if it can be pulled around the
blade by hand without sagging (wear protective gloves).
When the saw chain is pulled with a tensile force of 10 N (approx.
1 kg), the distance between saw chain and guide bar should be not
more than 4 mm.
For new saw chains, the chain tension must be re-adjusted again
after a short time of operation.
Filling Chain Oil
1. Unscrew the cap of the oil
tank (5) and fill in suitable
chain oil.
2. Wipe the tank clean and
close the oil tank with the
cap.
Hints:
Do not operate the pole pruner without sufficient chain lubrication.
Insufficient lubrication will shorten the service life of the saw chain
and the guide bar.
The gardening tool is equipped with automatic oiling mechanism.
As soon as the motor is running, the oil flows to the guide bar.
Regularly check the oil level in the tank and re-fill with oil in time.
Only use biodegradable chain oil (e.g. Westfalia Biological
Adhesive, article number 76 63 78). Pour the chain oil into the oil
tank (8). Do not use motor oil or other mineral oils.
Clean the filler cap and the area around it to avoid contaminating
the oil tank.
Oil

13
Pole Pruner
If the oil level in the tank does not drop, the oil duct in the housing
and the guide bar may be clogged. Check and clean it as needed.
Caution! The saw can re-oil. Please note that the saw re-oils after
use and oil may leak out if it is stored on its side or on the head.
This is a normal process. As each saw it checked during production
and tested with oil, a small residue may be in the tank.
Checking the Chain Lubrication
Hold the running chain saw about
15 cm over a suitable surface for a few
moments. If the oil thrown from the
chain forms a slight track on the
surface the lubrication is sufficient.
Do not use the pole pruner if the
lubrication is insufficient.
Operation
Observe the country-specific and local authority regulations. Do not
work during commonly accepted or mandatory rest periods.
• Before starting the gardening tool, check:
- the tension of the saw chain,
- the oil level,
- all nuts and screws are fitted firmly
• Wear suitable protective clothing.
• Adjust the working length of the gardening tool (using the extension
pole).
• Put on the shoulder strap.
• Check you are standing safely and check your working surroundings.

3. Make sure the safety pin locks
securely into the provided
opening. You will hear a click
sound.
4. Tighten the pole by using the
screw cap (10).
When not using the extension
pole, re-attach the safety caps
(2).
Attention! The grass trimmer and brush cutter attachment may not be
operated together with the extension pole (1)! There is risk of injury!

Operation
There is no need to force the pole pruner into the cut. Run the motor
and only lightly press on the tool. If the saw jams in the cut, do not try
and pull the tool out by force.
Cutting Branches –Cutting thick Branches on a Tree
When cutting off larger
branches, you should first
cut into the branch from
below. First cut into the
branch from below outside
the place where you intend
to cut off the branch. The
cut should go from one
third to halfway through the
branch (step 1). This
prevents the branch from
buckling when you cut into
the branch from the top
outside the first cut (step
2).
Finally, cut off the stump
with one clean cut (step 3).
Before you start cutting, attach the branch at the limit stop of the
saw.
