ASSEMBLY
CAUTION: Before plugging in the tool, always
check to see that the switch lever actuates properly
and returns to the "OFF" position when released.
CAUTION: Always be sure that the tool is
switched off and unplugged before carrying out
any work on the tool.
Installing side grip (handle)
CAUTION: Always be sure that the side grip is
installed securely before operation.
CAUTION: For your safety, this tool is equipped
with lock-off lever which prevents the tool from unin-
tended starting. NEVER use the tool if it runs when
you simply pull the switch lever without pulling the
lock-off lever. Return the tool to our authorized ser-
vice center for proper repairs BEFORE further usage.
CAUTION: Do not pull the switch lever hard
without pulling the lock-off lever. This can cause
switch breakage.

pose and function of lock-off lever.
Installing or removing wheel guard
WARNING: When using a depressed center wheel,
flap disc, flex wheel or wire wheel brush, the wheel
guard must be fitted on the tool so that the closed side
of the guard always points toward the operator.
To prevent the switch lever from being accidentally
pulled, a lock-off lever is provided.
To start the tool, pull the lock-off lever toward the opera-
tor and then pull the switch lever.
To stop the tool, release the switch lever.

While pushing the lock lever, mount the wheel
guard with the protrusions on the wheel guard aligned
with the notches on the bearing box.

The tool electronically detects situations where the wheel
or accessory may be at risk to be bound. In such situation,
the tool automatically shuts off the power to prevent further
rotation of the spindle (this does not prevent kickback).
At this time, the indication lamp blinks in red and shows
the Active Feedback sensing Technology is working.
To restart the tool, switch off the tool first, remove the
cause of sudden drop in the rotation speed, and then
turn the tool on.

While pushing the lock lever toward A, hold down
the portions B of the wheel guard as shown in the figure.

While pushing the lock lever toward A, rotate the wheel
guard toward C, and then, change the angle of the wheel
guard according to the work so that the operator can be pro-
tected. Align the lock lever with one of the holes in the wheel
guard, and then release the lock lever to lock the wheel guard.
