Cutting angle adjustment
CAUTION:
When adjusting the cutting angle, always switch
off the motor and remove the battery cartridge then lay the
ground trimmer flat on the ground.
CAUTION:
Do not adjust the cutting angle when the ground
trimmer is in an upright position.
CAUTION:
Always secure the blades with the blade cover
provided before adjusting cutting angle.
CAUTION:
Always use the cutter unit handle when adjust-
ing the cutting angle. Grabbing the blade may result in a personal
injury.
Hold the cutter unit handle and move the blade to your desired angle
while pulling the angle lock. The cutting angle can be adjusted in the
range as illustrated in the figure.

NOTE: The cutter unit is fastened only with certain angles along-
side 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.
In case the cutter unit is loose, the bolt (the axis of angle adjustment)
needs to be tightened.
Set the socket wrench and the hex wrench on the bolt. Adjust the
tightness of the cutter unit by turning hex wrench and then fasten the
bolt by turning the socket wrench.

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.
2. Tighten the hex bolts lightly till they stop. And then, screw them
back a quarter to half turn each to gain necessary clearance.
3. Hold the hex bolts and tighten the nuts.
4. Apply light oil on the friction surface of the blades.
5.
Start the motor and operate the throttle on and off for a minute.
6. Measure the time necessary for the blades to stop after releasing
the throttle. If it is two seconds or longer, switch off the motor and
