CAUTION:
• If the tool is operated continuously at low speeds for a
long time, the motor will get overloaded and heated up.
• The speed adjusting dial can be turned only as far as 5
and back to 1. Do not force it past 5 or 1, or the speed
adjusting function may no longer work.
The tools equipped with electronic function are easy to
operate because of the following features.
• Electronic constant speed control
Possible to get fine finish, because the rotating speed
is kept constantly even under the loaded condition.
• Soft start feature
Soft start because of suppressed starting shock.
• Overload protector
When the tool would be employed over the admissible
load, it will stop automatically to protect the motor and
wheel. When the load will come to the admissible level
again, the tool can be started automatically.
ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
Installing side grip (handle) (Fig. 4 & 5)
Remove one of the screws which secure gear housing
and head cover, then screw the side grip on the tool.
CAUTION:
• Always be sure that the side grip is installed securely
before operation.
Installing or removing abrasive disc (Fig. 6 & 7)
Remove all dirt or foreign matter from the pad.
Screw the pad onto the spindle with pressing the shaft
lock.
Attach the disc to the pad so carefully that the edges of
disc and pad overlap each other without protruding.
To remove the abrasive disc, pull off its edge from the
pad.
IF USED AS A GRINDER
Removing head cover (Fig. 8 & 9)
When use as a grinder, remove the head cover. Loosen
the screws and pull off the head cover while pulling out its
corners.
Installing side grip (handle) (Fig. 10)
CAUTION:
• Always be sure that the side grip is installed securely
before operation.
Screw the side grip securely on the position of the tool as
shown in the figure.
Installing or removing wheel guard
(For depressed center wheel, multi disc /
abrasive cut-off wheel, diamond wheel)
For tool with locking screw type wheel guard (Fig. 11)
WARNING:
• When using a depressed center grinding wheel/Multi-
disc, flex wheel or wire cup brush, the wheel guard
must be fitted 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.)
Mount the wheel guard with the protrusion on the wheel
guard band aligned with the notch on the bearing box.
Then rotate the wheel guard around 180 degrees coun-
terclockwise. Be sure to tighten the screw securely.
To remove wheel guard, follow the installation procedure
in reverse.
Installing or removing depressed center grinding
wheel/Multi-disc (accessory)
Mount the inner flange onto the spindle. Fit the wheel/
disc on the inner flange and screw the lock nut onto the
spindle.
(Fig. 12)
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.
(Fig. 13)
Installing or removing abrasive disc (optional
accessory) (Fig. 14)
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 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 disc, follow the installation procedure in
reverse.
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 grinding.
• 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.
• NEVER use tool with wood cutting blades and other
sawblades. Such blades when used on a grinder fre-
quently kick and cause loss of control leading to per-
sonal injury.
CAUTION:
• After operation, always switch off the tool and wait until
the wheel has come to a complete stop before putting
the tool down.
