2. Make sure the washer fl ange and spindle washer
are installed on spindle. Then, slide the disc
nut through the arbor hole in both the polishing
pad and the rubber backing pad, making sure
to spread the fi bers in the pad so the disc nut
seats on pad backing.
3. Push in the spindle lock button (located on left
side of gear case) and simultaneously screw the
disc nut & polishing pad assembly clockwise onto
the spindle. Securely hand-tighten the disc nut
and polishing pad.
4. To remove the polishing pad, push in the spindle
lock button and turn the disc nut counterclock-
wise to unscrew the assembly.

Hook and Loop Pads
Hook & loop pads are available in both wool/polyes-
ter and foam. Foam pads should be used on slower/
low speed dial settings when using polisher Cat.
Nos. 5540 and 5460. Foam pads are not recom-
mended for the inexperienced operator.
Foam pad Cat. No. 49-36-1550 is ideal for use
with clearcoat finishes and micro-fine rubbing
compounds. It will remove light surface scratches,
environmental pollutants, wet-sanding scratches
and hazy paint.
Foam pad Cat. No. 49-36-0650 is ideal for glazing
and fi nishing on clearcoat fi nishes. It will remove
buffi ng swirls, hard water spots, carwash brush
swirls and mild hazing. A centering tool, Cat. No.
49-67-0130, is supplied with hook and loop backing
pads, Cat. No. 49-36-2150, to properly align the
backing pad with the polishing pad, providing the
proper balance for your polisher.
1. To install wool/polyester bonnets, unplug the
tool and place it on a tool rest with the spindle
upright.
2. Make sure the washer fl ange and spindle washer
are installed on spindle. Then, slide the rubber
backing pad onto the spindle.
3. Push in the spindle lock button and screw the
disc nut onto the spindle clockwise. Securely
hand-tighten the disc nut.
4. Cover the rubber backing pad with the bonnet.
Securely tie bonnet strings and tuck the strings
into the bonnet so they do not interfere with
polishing.
5. To remove, untie and remove the bonnet. Push
in the spindle lock button and turn the disc nut
and rubber backing pad counterclockwise.
1. To install hook and loop pads, unplug the tool
and place it on tool rest with spindle upright.
2. Make sure washer fl ange and spindle washer
are installed on spindle. Then slide hook and
loop backing pad onto spindle.
3. Push in the spindle lock button and spin the
backing pad clockwise until it is securely hand-
tightened.
4. Insert the centering tool (supplied with the back-
ing pad) into the center hole in the hook and
loop backing pad. Push desired hook and loop
polishing pad over the centering tool so that
the polishing pad fastens to the hook and loop
backing pad. Remove centering tool.
5. To remove, "peel" off the polishing pad. Push in
the spindle lock button and rotate backing pad
counterclockwise to remove.
NOTE: Use side handles for better control and
safety.
OPERATION
WARNING To reduce the risk of injury,
wear safety goggles or glasses with side
shields.
WARNING To reduce the risk of injury,
always unplug tool before attaching or remov-
ing accessories or making adjustments. Use
only specifi cally recommended accessories.
Others may be hazardous.
Starting, Stopping and Controlling Speed
Cat. No. 5455: To start the tool, pull the trigger. To
stop the tool, release the trigger.
Cat. Nos. 5540 & 5460 feature a dial speed control,
which controls the polisher's maximum rotations
per minute. The speed will remain variable to the
chosen dial setting by use of the trigger switch. Dial
settings range from 1 through 5. Lower numbers
correspond to lower speeds and higher numbers
correspond to higher speeds. Generally, lower
speeds are recommended for tight work areas and
higher speeds are ideal for large surface areas. Use
the setting that best suits your job.
To control the speed, set the dial to the desired
number. Then pull the trigger. Increase or decrease
pressure on the trigger to vary the speed. To stop
the tool, release the trigger.
Polishing
Always use side handle for proper control. Move the
polisher back and forth in long, sweeping strokes.
Too much pressure, the wrong angle or improper
motion may cause swirl marks or burning.
For detailed polishing instructions, read the in-
structions provided with your fi nishes, waxes and
polishes.
Preventing Snagging
Snagging occurs when polishing pads get caught
on rough edges of a work surface. Snagging can
cause the tool to suddenly "kick back" and it may
cause the pad to burn through the paint. To reduce
the risk of snagging, use the polisher at low speeds
when polishing rough surfaces. For tricky areas
such as near trim or between a mirror and window
on a car, do not take chances with a polisher. Polish
these surfaces by hand.
When using Cat. Nos. 5460 and 5540 with the
trigger speed control, release the trigger slightly
so the rotation of the pad is slowed.
To prevent snagging while using Cat. No. 5455
without trigger speed control, it is best to use the
"coast-down" technique to avoid snagging. To
coast-down, turn the motor ON for a few seconds,
then turn it OFF and apply the polishing pad to the
surface. This way, when the pad touches the work
surface, it will be rotating more slowly than it is when
the motor is ON. Use coast-down when working in
areas where crevices or pockets are present.
Preventing Burning Through Paint
It is easy to burn through the paint on a surface.
This can occur if you polish at too high a speed or
if you allow the polishing pad to stay in one spot
for even a short period of time. To prevent burning
through paint, use very light pressure and keep the
polisher moving constantly, especially when work-
ing near edges or where there are abrupt changes
in the contour of the work surface.
Be particularly careful when using Cat. No. 5540,
which are high RPM polishers and are more likely
to burn through paint.
WARNING To reduce the risk of in-
jury, keep the cord set away from the path
of the polisher. Otherwise the cord set may
become caught by the pad and wrap around
the spindle; this may cut through the cord
and expose live wires or make the gear box
electrically "live."
WARNING To reduce the risk of injury,
follow instructions for preventing snagging.
Snagging may cuase the tool to kick back
and the operator to suddenly lose control of
the tool. Always use side handle to maintain
control.
