WARNING:
When inspecting or maintaining the equipment,
always put the hedge trimmer down. Assembling or adjusting
the equipment in an upright position may result in serious
injury.
WARNING:
Follow the warnings and precautions in the
chapter "IMPORTANT SAFETY INSTRUCTIONS" and the
instruction manual of the power unit.
Inspecting blades
Check the blades daily for damage, crack and dull edge. Ask our
authorized service center to replace damaged blades or sharpen dull
blades.
Adjusting the blade clearance
The upper/lower blades wear out gradually after operations. If you
cannot get a clean cut though the blades are sharp enough, adjust
the clearance as follows.
The tightness of the hex bolt decides the clearance of the blades.
The nut holds the hex bolt with certain tightness. Too loose clearance
causes blunt cut, but too tight clearance causes unnecessary heat
and sooner worn-out of the blades.
1. Loosen the nuts with a wrench.
Tighten the hex bolts lightly till they stop. And then, screw them
2.
back a quarter to half turn each to gain necessary clearance.
Hold the hex bolts and tighten the nuts.
3.
Apply light oil on the friction surface of the blades.
4.
Start the motor and operate the throttle on and off for a minute.
5.
Measure the time necessary for the blades to stop after releasing
6.
the throttle. If it is two seconds or longer, switch off the motor and
repeat the step 1 to 6.
Switch off the motor and touch the blade surface. If they are not
7.
too hot to touch, you have made a proper adjustment. If they are too
hot to touch, turn the hex bolts back a little and repeat the step 5 to 7.

Lubricating moving parts
Follow the instruction of the frequency and amount of
NOTICE:
grease supplied. Otherwise insufficient lubrication may damage
moving parts.
► Fig.8
Gear case:
Apply grease every 25 working hours.
The grease hole locates under the bolt. Remove the bolt to
1.
lubricate.
Add approx. 5 g (7 cc) of grease to the grease hole.
2.
3. Return the bolt after lubrication.
► Fig.9: 1. Grease hole
NOTE: After filling correct amount of grease, grease will come out a
bit from the base of the blade during the first operation.
Drive axle:
Apply grease every 25 working hours.
Overall inspection
• Tighten loose bolts, nuts and screws.
• Check for damaged parts and blades. Ask our authorized service
center to replace them if necessary.
