Inspecting blades
Check the blades daily for damage, crack and dull edge. Ask Makita 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.

Loosen the nuts (A) with a wrench.
Tighten the bolts (B) lightly till they stop. And then, screw them back a quarter to half turn each to gain necessary clearance.
Hold the bolts (B) and tighten the nuts (A).
Apply light oil on the friction surface of the blades.
Start the motor and operate the throttle on and off for a minute.
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.
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.
