MOUNTING OF CUTTER BLADE OR NYLON CUTTING HEAD

Be sure to use genuine MAKITA cutter blades or nylon
cutting head.
– The cutter blade must be well polished, free of cracks or breakage. If the
cutter blade hits against a stone during operation, stop the engine and check
the blade immediately.
– Polish or replace the cutter blade every three hours of operation.
– If the nylon cutting head hits against a stone during operation, stop the
engine and check the nylon cutting head immediately.
CAUTION: The appropriate protector must always be installed, for your own
safety and in order to comply with accident-prevention regulations.
Operation of the equipment without the guard being in place is not
permitted.
The outside diameter of the cutter blade must be 230 mm (9 -
1/16"). Never use any blades surpassing 230 mm (9 - 1/16") in
outside diameter.
Turn the machine upside down, and you can replace the cutter blade or nylon
cutting head easily.
– Insert the hex wrench through the hole in the gear case and rotate the
receiver washer (4) until it is locked with the hex wrench.
– Loosen the nut (1) (left-hand thread) with the socket wrench and remove the
nut (1), cup (2), and clamp washer (3).
Mounting of cutterblade with the hex wrench still in place
– Mount the cutter blade onto the shaft so that the guide of the receiver washer
(4) fits in the arbor hole in the cutter blade. Install the clamp washer (3), cup
(2), and secure the cutter blade with the nut (1).
[Tightening torque: 13 - 23 N-m]
NOTE: Always wear gloves when handling the cutter blade.
NOTE: The cutter blade-fastening nut (with spring washer) is a consumable
part. If there appears any wear or deformation on the spring washer,
replace the nut.
Mounting of nylon cutting head
– The clamp washer (3), cup (2), and nut (1) are not necessary for mounting
the nylon cutting head. The nylon cutting head should go on top of the
receiver washer (4).
– Insert the hex wrench through the hole in the gear case and rotate the
receiver washer (4) until it is locked with the hex wrench.
– Then screw the nylon cutting head onto the shaft by turning it counter-
clockwise.
– Remove the hex wrench.
