Installing or removing wheel guard
(For depressed center wheel)
WARNING:
When using a depressed center
wheel, the wheel guard must be fitted on the tool
so that the closed side of the guard always points
toward the operator.
Mount the wheel guard with the protrusions on the
wheel guard band aligned with the notches on the bear -
ing box. Then rotate the wheel guard to such an angle
that it can protect the operator according to work. Be
sure to tighten the screw securely.
To remove wheel guard, follow the installation proce-
dure in reverse.

WARNING:
When using a depressed center
wheel, the wheel guard must be fitted on the tool
so that the closed side of the guard always points
toward the operator.
CAUTION:
Make sure that the mounting part
of the inner flange fits into the inner diameter of
the depressed center wheel perfectly. Mounting
the inner flange on the wrong side may result in the
dangerous vibration.
Mount the inner flange onto the spindle. Make sure to fit
the straight part of the inner flange onto the straight part
at the bottom of the spindle. Fit the depressed center
wheel on the inner flange and screw the lock nut onto
the spindle.
In case of mounting a depressed center wheel thinner
than 4 mm (5/32"), place the lock nut so that the protru-
sion on the lock nut faces outside. Otherwise, place it
so that the protrusion on it fits into the inner diameter of
the wheel.

wrench and securely tighten clockwise.

OPERATION
WARNING:
It should never be necessary to
force the tool. The weight of the tool applies ade-
quate pressure. Forcing and excessive pressure
could cause dangerous wheel breakage.
WARNING:
ALWAYS replace wheel if tool is
dropped while grinding.
WARNING:
NEVER bang or hit grinding disc
or wheel onto work.
WARNING:
Avoid bouncing and snagging
the wheel, especially when working corners,
sharp edges etc. This can cause loss of control and
kickback.
WARNING:
NEVER use tool with wood cutting
blades and other saw blades.
Such blades when
used on a grinder frequently kick and cause loss of
control leading to personal injury.
CAUTION:
Never switch on the tool when it
is in contact with the workpiece, it may cause an
injury to operator.
CAUTION:
Always wear safety goggles or a
face shield during operation.
CAUTION:
After operation, always switch off
the tool and wait until the wheel has come to a
complete stop before putting the tool down.
CAUTION:
ALWAYS hold the tool firmly with
one hand on housing and the other on the side
grip (handle).
Grinding operation
Turn the tool on and then apply the wheel or disc to the
workpiece.
In general, keep the edge of the wheel or disc at an
angle of about 15° to the workpiece surface.
During the break-in period with a new wheel, do not
work the grinder in forward direction or it may cut into
the workpiece. Once the edge of the wheel has been
rounded off by use, the wheel may be worked in both
forward and backward direction.
Without side grip
only for MT964
ALWAYS hold the tool firmly with only one hand on
housing. Do not touch the metal part.
