Cutting techniques
• When removing branches, hold the machine at an angle ranging from a maximum 60° to horizontal in order to avoid being struck by a falling branch.
• Saw off the lower branches on the tree first. By doing so, it is easier for the cut branches to fall to the ground.
• At the end of the cut, the weight of the saw suddenly increases for the user, because the saw is no longer supported on the branch. There is the risk of losing
control of the saw.
• Only pull the saw out of the cut with the saw chain running. By doing so, you can prevent it from getting jammed.
• Do not saw with the tip of the guide bar.
• Do not saw into thick the branch formations. This impedes the tree's ability to heal the wound.
Sawing off smaller branches (Fig. O)
Place the stop face of the saw on the branch. This prevents fitful movements of the saw at the beginning of the cut. Applying light pressure, guide the saw
through the branch from top to bottom.
Sawing off larger and longer branches (Fig. P)
Make a relief cut when sawing larger branches.
a) First saw through 1/3 of the branch diameter from bottom to top using the top side of the guide bar.
b) Then saw from top to bottom to the first cut using the bottom side of the guide bar.
c) Saw off longer branches in sections in order to maintain control over the location of impact.
Kickback
The term kickback refers to when the pole saw suddenly jumps up and back. This is usually caused by the workpiece coming into contact with the guide bar tip
or the clamping of the saw chain.
A kickback generates abrupt, powerful forces. Therefore, the pole saw usually reacts in an uncontrolled manner.
The consequence is often the severe injury of the user or nearby persons.
The danger of a kickback is greatest if you apply the area near the guide bar tip to a branch, because the leverage effect is greatest there. Therefore, always
apply the saw as flatly as possible.
Attention!
• Always make sure that the chain tension is correct!
• Only use properly functioning chainsaws!
• Only work with a saw chain sharpened according to regulations!
• Never saw with the upper edge or tip of the guide bar!
• Always hold the chainsaw firmly with two hands!
Sawing wood under tension
Sawing wood which is under tension necessitates elevated caution! Wood that is under tension and is then released from that tension when cut occasionally
reacts in a completely uncontrolled manner. This can result in severe to deadly injuries. Such work may only be performed by trained specialists.

Cleaning and maintenance

WARNING! Always switch the product off, disconnect it from power supply and let the product cool down before performing inspection, maintenance and
cleaning work!
Keep the product clean. Remove debris from it after each use and before storage.
Regular and proper cleaning will help ensure safe use and prolong the life of the product.
Inspect the product before each use for worn and damaged parts. Do not operate it if you find broken and worn parts.
WARNING! Only perform repairs and maintenance work according to these instructions!
All further works must be performed by a qualified specialist!
Sharpening saw chain
NOTE: Never saw with a blunt chain. The saw chain is blunt if you have to push the product into the tree and the chips are very small.
Have your chain (2) sharpened professionally at authorized service centre or sharpen the chain yourself using a proper sharpening kit.
WARNING! Only sharpen the saw chain yourself if you are trained and have experience!
Use proper tools to sharpen the saw chain!
Effective working with the chainsaw is only possible if the saw chain is in good condition and sharp. This also reduces the risk of kickback. The saw chain can
be re-sharpened by authorized service center.
Do not attempt to sharpen the saw chain yourself unless you have the necessary special tools and experience.
Checking the automatic chain lubrication
You should check the operation of the automatic chain lubrication system on a regular basis in order to guard against overheating and the associated damage
to the cutter rail and the saw chain.
To do this, point the tip of the cutter rail towards a smooth surface (board, section of a cut tree) and allow the pole saw to run. If an increasing oil trace
becomes evident during this process then the automatic chain lubrication system is working properly. If no clear oil trace is evident then please refer to the
corresponding instructions in "Troubleshooting".
If the information contained there still fails to remedy the situation then please dial our helpline. Important! Do not actually touch the surface with the tip of
the cutter rail when performing this test. Keep a safe distance (approx. 20 cm).
Chain and bar replacement
Assemble the guide bar and saw chain before operation. Follow the operating instructions step-by-step and use the pictures provided as a visual guide to easily
assemble the product.
Warning! Read all the instructions carefully! Do not connect the product to the power supply until it is completely assembled! Always wear gloves during
assembly!
Use only the guide bar (1) and saw chain (2) according to the technical data of the product.
Place the product on a suitable flat surface with the cover (6) facing upwards.
Loosen the Knob (4) anticlockwise and remove the cover (6) (Fig. Q)
