OPERATING INSTRUCTIONS
Installing wheel guard (Fig. 1)
Important:
Always be sure that the tool is switched off and
unplugged before installing or removing the wheel guard.
When installing a depressed center wheel or an abrasive
cut-off wheel, always use a wheel guard. Mount the
wheel guard with the tab on the wheel guard band
aligned with the notch on the bearing box. Then rotate
the wheel guard 160 degrees counterclockwise. Be sure
to tighten the screw securely.
Installing side grip (auxiliary handle) (Fig. 2)
Important:
Always be sure that the tool is switched off and
unplugged before installing or removing the side grip.
Always install the side grip on the tool securely before
operation. The side grip can be installed in any of three
positions on the sides of the tool, whichever is convenient
and keeps the guard properly positioned. Always hold the
tool’s switch handle and the side grip firmly with both
hands during operation.
Shaft lock (Fig. 3)
Press the shaft lock to prevent spindle rotation when
installing or removing accessories.
CAUTION:
Never actuate the shaft lock when the spindle is moving.
The tool may be damaged.
Installing or removing depressed center wheel
(Fig. 4 & 5)
Important:
Always be sure that the tool is switched off and
unplugged before installing or removing the wheel.
Mount the inner flange onto the spindle. Fit the wheel on
over 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.
NOTE:
Super flange
Models 9067F, 9069F, 9067SF and 9069SF are stan-
dard-equipped with a super flange.
Only 1/3 of efforts needed to undo lock nut, compared
with conventional type.
Switch action (Fig. 6)
CAUTION:
Before plugging in the tool, always check to see that the
switch trigger actuates properly and returns to the “OFF”
position when released.
For U.K., Australia, New Zealand, France, Réunion
and Algeria
To prevent the trigger from being accidentally actuated, a
lock lever is provided. To start the tool, push the lock lever
in and then pull the trigger. Release the trigger to stop.
For Germany, Austria, Italy, Netherlands, Belgium,
Spain, Portugal, Denmark, Sweden, Norway, Finland,
Greece and South Africa
To prevent the trigger from being accidentally actuated, a
lock lever is provided. To start the tool, push the lock lever
in and then pull the trigger. Release the trigger to stop.
For continuous operation, push the lock lever in, pull the
trigger and then push the lock lever further in. To stop the
tool from the locked position, pull the trigger fully, then
release it.
For other countries than the above countries
To start the tool, simply pull the trigger. Release the trig-
ger to stop. For continuous operation, pull the trigger and
then push the lock lever. To stop the tool from the locked
position, pull the trigger fully, then release it.
NOTE:
Models 9067S and 9069S begin to run slowly when they
are turned on. This soft start feature assures smoother
operation and less operator fatigue.
Operation (Fig. 7)
CAUTION:
After operation, always switch off the tool and wait until
the wheel has come to a complete stop before putting the
tool down.
Hold the tool firmly. 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° – 30° to the workpiece surface. During the
break-in period with a new wheel, do not work the tool in
the B direction or it will cut into the workpiece. Once the
edge of the wheel has been rounded off by use, the
wheel may be worked in both A and B directions.
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.
• Continued use of a worn-out wheel may result in wheel
explosion and serious personal injury. Depressed cen-
ter wheel should not be used after it has been worn
down to 115 mm in diameter. Use of the wheel after
this point is unsafe and it should be removed from ser-
vice and rendered unusable by intentional destruction.
