attempting
to
maintenance on the tool. Failure to switch off
and remove the battery cartridge may result in
serious personal injury from accidental start-up.
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.
NOTICE:
Never use gasoline, benzine, thinner, alcohol or
•
the like. Discoloration, deformation or cracks may
result.
Inspecting blades
Check the blades daily for damage, crack and dull edge.
Ask Makita Authorized or Factory Service Centers to
replace damaged blades or sharpen dull blades.
Adjusting the blade clearance

013909
013910
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.
perform
inspection
1. Nut
2. Truss bolt
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 with a wrench.
2.
Tighten the bolts lightly till they stop. And then,
screw them back a quarter to half turn each to
or
gain necessary clearance.
3.
Hold the bolts and tighten the nuts.
4.
Apply light oil on the friction surface of the blades.
5.
Switch on the tool and pull the switch trigger.
6.
Measure the time necessary for the blades to
stop after releasing the switch trigger. If it is two
seconds or longer, switch off the tool and repeat
the step 1 to 6.
7.
Switch off the tool and remove the battery
cartridge, 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 back a little and repeat the step 5 to 7.
Lubricating moving parts
NOTICE:
Follow the instruction of the frequency and amount
•
of
grease
lubrication may damage moving parts.

The grease hole locates under the bolt. Remove the bolt
to lubricate.
Add approx. 3 g (4 cc) of grease to the point A of the
gearbox and 5 g (7 cc) of the grease 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.
