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.
In case the cutter unit is loose, the bolt (A) (the axis of angle
adjustment) needs to be tightened. (Fig. 8)
1. Set the socket wrench (C) and the hex wrench (B) on the bolt (A).
2. Adjust the tightness of the cutter unit by turning hex wrench (B),
and then fasten the bolt by turning the socket wrench (C).
Note:
- Do not fasten the cutter unit too tight. The angle of the cutter unit
can not be changed if it is too tight.

Operation

WARNING:
• If the blades move at idle, adjust the idle speed of the engine
down. Otherwise you cannot stop the blades with throttle off and
it may cause serious injury.
• Follow the warnings and precautions in the chapter "Safety
precautions" and the instruction manual of the power unit.
Horizontal cut (Fig. 9)
When trimming hedges horizontally, follow the steps below.
1. Pull the throttle lever fully.
2. Apply the blades to the hedge with an angle of 15° to 30°.
3. Trim the hedge with a swinging movement.
Vertical cut (Fig. 10)
When trimming hedges vertically, follow the steps below.
1. Pull the throttle lever fully.
2. Apply the blades to the hedge parallel to each other.
3. Trim the hedge from the bottom upwards with a swinging
movement.

Inspection and maintenance

WARNING:
• Before inspecting or maintaining the equipment, switch off the
motor and remove the spark plug cap or the battery cartridge.
Otherwise blades or other parts may move and result in serious
injury.
• Before handling or working around blades, wear protective gloves
and put the blade cover onto blades. During the assembly or
adjustment, your fingers may contact with blades and it may
cause serious injury.
• 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.
• Follow the warnings and precautions in the chapter "Safety
precautions" and the instruction manual of the power unit.
Inspecting blades
Check the blades daily for damage, crack and dull edge. Ask
Dolmar authorized service center to replace damaged blades or
sharpen dull blades.
Adjusting the blade clearance (Fig. 11)
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 truss bolt decides the
clearance of the blades. The nut holds the truss 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 (A) with a wrench.
2. Tighten the bolts (B) lightly till they stop. And then, screw them
back a quarter to half turn each to gain necessary clearance.
3. Hold the bolts (B) and tighten the nuts (A).
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
repeat the step 1 to 6.
7. Switch off the motor and touch the blade surface. If they are not
too hot to touch, you have made a proper adjustment. If they are
too hot to touch, turn the bolts (B) back a little and repeat the
step 5 to 7.
Lubricating moving parts (Fig. 12)
NOTICE: Follow the instruction of the frequency and amount of
grease supplied. Otherwise insufficient lubrication may damage
moving parts.
Gear case:
The gearbox of the pole hedge trimmer should be greased every
25 working hours. The grease hole locates under the bolt. Remove
the bolt to lubricate. Add approx. 3 g (4 cc) of lubricant to the
point A of the gearbox and 5 g (7 cc) of the lubricant to the point B
respectively via the grease holes. Return the bolt after lubrication.
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 hours of operation.
Overall inspection
• Tighten loose bolts, nuts and screws.
• Check for damaged parts and blades. Ask Dolmar authorized
service center to replace them.

Storage

WARNING: Follow the warnings and precautions in the chapter
"Safety precautions" and the instruction manual of the power unit.
(Fig. 13)
When storing the hedge trimmer attachment separated from the
power unit, put the cap onto the end of the shaft.
