the slider switch forward and push the front down until it locates in the lock position. To
turn the tool off, press the rear of the slider switch. Spring action returns the switch to
the off position.
CAUTION: Hold the side handle (5) and body of the tool (4) firmly to maintain control
of the tool at start up and during use and until the wheel or accessory stops rotating.
Make sure the wheel has come to a complete stop be fore laying the tool down.
CAUTION: Allow the tool to reach full speed before touching tool to the work surface.
Lift the tool from the work surface before turning the tool off.
ROTATING THE GEAR CASE (FIG. E)
Turn off and unplug tool before making any
adjustments or removing or installing accessories.
Before reconnecting the tool, depress and release the
trigger switch to ensure that the tool is off.
1. Remove guard and flanges from tool.
2. Remove the four corner screws attaching the gear
case to motor housing.
3. Separating the gear case from motor housing not
more than 1/4 in., rotate the gear case head to
desired position.
NOTE: If the gear case and motor housing become separated by more than 1/4 in., the
tool must be serviced and re-assembled by a Porter Cable service center. Failure to
have the tool serviced may cause brush, motor and bearing failure.
4. Re-install screws to attach the gear case to the motor housing.
Tighten screws to 18 in./lbs. torque. Overtightening could cause screws to strip.
SPINDLE LOCK
The spindle lock button (6) is provided to prevent the spindle from rotating when installing
or removing wheels. Operate the spindle lock only when the tool is turned off and the
wheel has come to a complete stop.
WARNING: Do not engage the spindle lock while
the tool is operating. Damage to the tool will result
and attached accessory may spin off possibly
resulting in injury.
To engage the lock, depress the spindle lock button
shown in figure E1 and rotate the spindle until you are
unable to rotate the spindle further.

MOUNTING NON-HUBBED WHEELS
WARNING: To prevent accidental operation, turn off and unplug tool before
performing the following operations. Failure to do this could result in serious
personal injury.
Depressed center Type 27 grinding wheels must be used with included flanges. See
pages 9 and 10 of this manual for more information.
1. Figure F - Install the unthreaded backing flange
(11) on spindle (12) with the raised section (pilot)
against the wheel.
2. Place wheel against the backing flange, centering
the wheel on the raised section (pilot) of the
backing flange.
3. Figure G - While depressing the spindle lock
button, thread the threaded clamp nut (13) on
spindle.
• Figure H - If the wheel you are installing is more than 1/8 inch
(3mm) thick, place the threaded clamp nut on the spindle so
that the raised section (pilot) fits into the center of the wheel.
• Figure I - If the wheel you are installing is 1/8 inch (3mm)
thick or less, place the threaded clamp nut on the spindle so
that the raised section (pilot) is not against the wheel.
4. While depressing the spindle lock button (6), tighten the
threaded clamp nut with included wrench.
5. To remove the wheel, depress the spindle lock button and
loosen the threaded clamp nut with included wrench.
NOTE: If the wheel spins after the threaded clamp nut is tightened, check the orientation
of the threaded clamp nut. If a thin wheel is installed with the pilot on the clamp nut against
the wheel, it will spin because the height of the pilot prevents the clamp nut from holding
the wheel.
SURFACE GRINDING WITH GRINDING WHEELS
1. Allow the tool to reach full speed before touching the tool to the work surface.
2. Apply minimum pressure to the work surface, allowing the tool to operate at high
speed. Grinding rate is greatest when the tool operates at high speed.
3. Figure J - Maintain a 20˚ to 30˚ angle between the tool and work surface.
