• If the cutting disc halts in mid operation easily, the V-belt
has slackened. If this is the case, adjust tension using the
following procedure.

(2) Turn the tension adjustment screw to the right (clockwise)
until the indicator nut reaches the marked position in order to
increase the tension of the V-belt.
(3) Once V-belt tensioning is complete, firmly retighten the belt
cover tightening nuts.
• If the cutting disc stops easily even though the tension of the
V-belt has been adjusted, or the V-belt breaks, replace with a
new V-belt.
2. Changing the V-belt
(1) Loosen tightening nut, and turn tension adjustment screw to
the left until the end of the screw is visible.
(2) Remove tightening nuts, and then remove belt cover.
(3) Next, remove the three mounting screws, and remove the
clutch cover.
(4) Remove the old V-belt, and fit on a new V-belt. Now,
remount the clutch cover followed by belt cover.
(5) Adjust tension as shown in the Adjusting V-belt tension
section.

Cleaning the protection hood

Over time, the inside of the protection hood can become caked
with material residue (especially from wet cutting), which if
allowed to accumulate can hinder the free rotation of the cutting
disc. For this reason the hood must be cleaned out from time to
time.
Take off the cutting wheel and remove the accumulated material
from inside the hood with a strip of wood or similar implement.
Clean the shaft and all disassembled parts with a cloth.
NOTE: To install the cutting wheel see "Mounting the cutting
disc".
IMPORTANT:
Because many of the parts and assemblies not mentioned
in this Instruction Manual are vital to the safety of the unit,
and because all parts are subject to a certain amount of wear
and tear, it is important for your own safety that you have the
unit checked and maintained regularly by a MAKITA service
center.
IMPORTANT:
If the cutting wheel breaks during cutting, the
Power Cutter must be repaired by a MAKITA
service centre before being used again!
