Adjusting the cutting angle
WARNING:
• Do not operate the tool with the loose and unstable
cutter unit. Otherwise the cutter unit may change
direction suddenly and cause injury.
CAUTION:
• The cutter unit is fastened only with certain angles
alongside the groove on the unit. Make sure the cutter
unit sits properly. If the angle is not appropriate, the
clutch is cut and the tool does not operate.
• Do not adjust the cutter unit while the pole hedge
trimmer is in an upright position.
• Switch off the tool and remove the battery cartridge,
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. (Fig. 8)
You can adjust the cutting angle upwards to 45° and
downwards to 90°.
1. Remove the battery and lay the machine on the
ground.
2. To adjust the angle of the cutter unit, hold the handle
on the cutter unit with one hand, and hold the angle
lock as illustrated with the other hand.
3. Pull the angle lock gently, and change the angle of the
cutter unit. After adjusting the angle, return the angle
lock gently. (Fig. 9)
In case the cutter unit is loose, the bolt (the axis of angle
adjustment) needs to be tightened.
4. Set the socket wrench and the hex wrench on the bolt.
5. Adjust the tightness of the cutter unit by turning hex
wrench, and then fasten the bolt by turning the socket
wrench.
NOTE:
• Do not fasten the cutter unit too tight. The angle of the
cutter unit can not be changed if it is too tight.
