ample, by placing them in a saw-horse. Avoid cutting wood that lays on the ground. Avoid processing wood that is not protected
against movement during cutting.
Do not hold the handles of the pole saw above your shoulders during the operation. Do not operate the pole saw while standing
on the ladder. During work, adopt such a posture to eliminate the need to extend the hands to the full length.
Keep the chain clean. The chain must be sharpened and lubricated. This will ensure more e ffi cient and safer work. The chain can
be sharpened in a specialised service centre. Check the condition of the chain before each use. In the event of cracks, broken
teeth, or any other damage, replace the chain with a new one before starting work.
In case of fi nding any damaged or broken pole saw parts, stop working or do not start working. It is essential to replace damaged
parts before starting work.
Use the pole saw as intended. The tool is designed only for cutting wood. When working, watch out for metal elements or stones
that may be in the processed wood.
Use original spare parts only. Failure to use original spare parts may increase the risk of failure and lead to injuries.
The pole saw should be repaired only in service centres authorised by the manufacturer using original spare parts. This will mini-
mise the risk of accidents and damage to the equipment.
PRODUCT OPERATION
Preparing the pole saw for work
Caution! Disconnect the pole saw from the power supply before performing any assembly and adjustment work. Disconnect the
power cord plug from the mains socket!
Mount the guide bar and cutting chain before fi rst use.
Perform the assembly with protective gloves due to the risk of injury.
Unscrew the locking knob so that the entire side panel can be removed. Mount the guide bar and chain as shown in picture (II).
Make sure that the chain and guide bar are fi tted in the correct direction. The shape and direction of the links visible on the tool’s
housing should correspond to the direction of the chain visible on the links in the form of an arrow. If there is a visible indication of
the direction of the chain movement on the chain links, guide bar and housing, it should have the same direction.
Do not tension the chain yet, but make sure that the chain fi ts the guide bar slot and the teeth on the drive wheel. Fit the side
panel and tighten the locking knob in the direction of the arrow indicating a closed padlock. However, do it so as not to block the
possibility of the guide bar movement. Turn the tension knob in the direction of the arrow until the chain is tightened. The knob on
the underside has catches (II) that push the guide bar tightening the chain. Once the chain is tightened, tighten the locking knob
as far as it will go.
Check the chain tension. To do this, set the pole saw down and lift it by holding the middle part of the chain (III). During this test,
the chain at the holding point should rise above the guide bar within the range shown in the illustration. If the chain is tightened
too tight or too loose, loosen the locking knob a little and reset the chain tension level. The chain tension level should also be
checked every 10 minutes of operation.
Check the technical condition of the pole saw before connecting it to the power supply. If any damage is detected, it is forbidden
to connect it to the power supply before rectifying the damage.
Oil topping-up
Caution! Disconnect the pole saw from the power supply before performing any assembly and adjustment work. In the case of
mains-powered tools, disconnect them from the socket, and for battery-powered tools – disconnect their batteries.
For lubricating the chain and pole saw mechanisms use only oil intended for such purposes. It is forbidden to use worn-out motor
oil. It does not ful fi l its purpose, which can lead to damage to the pole saw mechanism.
Make sure that there is lubricating oil in the tank. Place the pole saw on the horizontal surface and check the oil indicator. The oil
level cannot be lower than the minimum indication. If there is no such indicator, the lower edge of the oil level indicator should be
taken as the reference level.
It is forbidden to use the pole saw with the empty oil tank. This can damage the chain, guide bar, and mechanisms of the pole
saw. It is recommended to start and operate the pole saw at least 3 meters from the place where the oil topping-up procedure was
performed. Perform oil topping-up away from fi re and heat sources.
To top up the oil, unscrew the oil tank cap, pour the oil inside the tank so the oil level levels out with a mark indicating the maximum
oil level or upper edge of the oil level indicator, then screw the tank cap fi rmly and securely. In case of spilling the oil, thoroughly
wash o ff any debris before connecting the pole saw to the power supply.
Adjustment
Adjustment of the tool length is possible by loosening the locking screw (V), then adjusting the tool length and tightening the
locking screw. The screw must be tightened with such force that the tool does not change length by itself during operation. In fi nite
adjustment of the tool length between the movement stops is possible.
Behind the auxiliary handle, there is a clip to attach a carrying strap. The belt clip should be attached to the clamp and hitch (VI)
so that the hitch lock secures the tool against accidental detachment during operation.
