Installing or removing wheel guard (For
depressed center wheel, flap disc, flex wheel,
wire wheel brush / abrasive cut-off wheel,
diamond wheel)
WARNING:
• When using a depressed center wheel, flap disc, flex
wheel or wire wheel brush, the wheel guard must be fit-
ted on the tool so that the closed side of the guard
always points toward the operator.
• When using an abrasive cut-off / diamond wheel, be
sure to use only the special wheel guard designed for
use with cut-off wheels. (In some European countries,
when using a diamond wheel, the ordinary guard can
be used. Follow the regulations in your country.)
For tool with locking screw type wheel guard (Fig. 6)
Mount the wheel guard with the protrusions on the wheel
guard band aligned with the notches on the bearing box.
Then rotate the wheel guard around 180° counterclock-
wise. Be sure to tighten the screw securely.
To remove wheel guard, follow the installation procedure
in reverse.
For tool with clamp lever type wheel guard (Fig. 7 & 8)
Pull the lever in the direction of the arrow after loosening
the screw. Mount the wheel guard with the protrusions on
the wheel guard band aligned with the notches on the
bearing box. Then rotate the wheel guard around 180°.
Tighten the wheel guard with fastening the screw after
pulling lever in the direction of the arrow. The setting
angle of the wheel guard can be adjusted with the lever.
To remove wheel guard, follow the installation procedure
in reverse.
Installing or removing depressed center wheel or
flap disc (optional accessory) (Fig. 9 & 10)
WARNING:
• When using a depressed center wheel or flap disc, the
wheel guard must be fitted on the tool so that the
closed side of the guard always points toward the oper-
ator.
Mount the inner flange onto the spindle. Fit the wheel/
disc on the inner flange and screw the lock nut onto the
spindle.
To tighten the lock nut, press the shaft lock firmly so that
the spindle cannot revolve, then use the lock nut wrench
and securely tighten clockwise.
To remove the wheel, follow the installation procedure in
reverse.
Super flange (Optional accessory)
Models with the letter F are standard-equipped with
Super flange. Only 1/3 of efforts needed to undo lock nut,
compared with conventional type.
CAUTION:
• Do not use super flange for models equipped with the
mechanical brake. Otherwise it may loosen when the
brake is activated.
Installing or removing Ezynut (optional
accessory) (Fig. 11, 12, 13 & 14)
CAUTION:
• Do not use Ezynut with Super Flange or angle grinder
with “F” on the end of the model No. Those flanges are
so thick that the entire thread cannot be retained by the
spindle.
Mount inner flange, abrasive wheel and Ezynut onto the
spindle so that Makita Logo on Ezynut faces outside.
Press shaft lock firmly and tighten Ezynut by turning the
abrasive wheel clockwise as far as it turns.
Turn the outside ring of Ezynut counterclockwise to
loosen.
NOTE:
• Ezynut can be loosened by hand as long as the arrow
points the notch. Otherwise a lock nut wrench is
required to loosen it. Insert one pin of the wrench into a
hole and turn Ezynut counterclockwise.
Installing or removing flex wheel (optional
accessory) (Fig. 15)
WARNING:
• Always use supplied guard when flex wheel is on tool.
Wheel can shatter during use and guard helps to
reduce chances of personal injury.
Follow instructions for depressed center wheel but also
use plastic pad over wheel. See order of assembly on
accessories page in this manual.
Installing or removing abrasive disc (optional
accessory) (Fig. 16)
NOTE:
• Use sander accessories specified in this manual.
These must be purchased separately.
Mount the rubber pad onto the spindle. Fit the disc on the
rubber pad and screw the sanding lock nut onto the spin-
dle. To tighten the sanding lock nut, press the shaft lock
firmly so that the spindle cannot revolve, then use the
lock nut wrench and securely tighten clockwise.
To remove the disc, follow the installation procedure in
reverse.
Installing or removing dust cover attachment
(Optional accessory) (Fig. 17)
WARNING:
•
Always be sure that the tool is switched off and
unplugged before installing or removing the dust
cover attachment.
Failure to do so causes damage to
the tool or a personal injury.
There are four pieces of dust cover attachment and each
is used in one of different positions.
Set the dust cover attachment so that the marking (A, B,
C or D) places as shown. Snap its pins in the vents.
Dust cover attachment can be removed by hand.
NOTE:
• Clean out the dust cover attachment when it is clogged
with dust or foreign matters. Continuing operation with
a clogged dust cover attachment will damage the tool.
OPERATION
WARNING:
• It should never be necessary to force the tool. The
weight of the tool applies adequate pressure. Forcing
and excessive pressure could cause dangerous wheel
breakage.
• ALWAYS replace wheel if tool is dropped while grind-
ing.
• NEVER bang or hit grinding disc or wheel onto work.
• Avoid bouncing and snagging the wheel, especially
when working corners, sharp edges etc. This can
cause loss of control and kickback.
