Adjustment of cutting angle
1. Stop the pole hedge trimmer engine and lay the machine on the ground.

of the cutter unit by turning it counter-clockwise.
3. Adjust the angle of the cutter unit and turn the clamp lever clockwise to secure.
•
The cutter unit can be adjusted anywhere between 45° and 90°.
Note:
- Do not adjust the cutter unit while the pole hedge trimmer is in an upright position.
- Move the I-O switch to the "O" position and lay the pole hedge trimmer flat on the
ground to adjust the cutting angle.
- Always secure the blades with the blade cover provided before adjusting
cutting angle.
MAINTENANCE
- Before performing any maintenance work on the pole hedge cutter (blade
cleaning, etc.), always stop the engine and wait until the engine has cooled
down. As an additional safety precaution, also remove the spark plug cap.
- Do not try to straighten or weld a bent or broken cutting blade. Always replace
damaged blades.
- Stop the engine at regular intervals to check the cutter blades for possible
damage (perform a tapping-resonance test to detect hard-to-see hairline
cracks). Always make sure that the teeth of the blades are sharp.
- Clean the pole hedge trimmer at regular intervals. During cleaning also check that
all screws, nuts and bolts are well tightened.
- To reduce the risk of fire, never service or store the pole hedge trimmer in the
vicinity of open fires.
- Always wear rugged protective gloves when handling the cutter blades.
- Contact your dealer for replacement cutter blades.
Sharpening the blade
If the cutting blades have become blunt and cutting performance is poor, have the
blades sharpened by an authorized service agent.
