always be sure the tool is switched off and unplugged before assembling parts, making adjust-
ments, assembling or replacing sanding discs, buffer pads, or checking function on the tool.
SPINDlE lOCK
Never depress the spindle lock button when the spindle is moving.
the spindle lock button is located on the top, forward portion of the gear housing. depress the
spindle lock button to prevent the spindle from rotating when installing or removing accessories.
SWITCH OPERATION
the tool can be locked on by depressing the lock-on button and the on/off switch at the same time,
then releasing pressure on the on/off switch. the lock-on feature is to relieve fatigue on the trigger
finger only. Grip tool firmly at all times while it is running, and keep both hands away from the Sand-
ing/Polishing wheel.
SPEED ADJUSTMENT DIAl
the speed adjustment dial is located on top of the rear handle. In this position slightly forward of the
switch trigger, the sander/polisher’s speed is easily adjusted by the operator’s thumb on the hand
grasping the tool on the rear handle.
With the switch trigger fully depressed and the tool running, tool speed can be changed by rotat-
ing the speed adjustment dial to a numbered setting from 1 to 6. tool speed increases as the dial is
moved in the direction of the number 6 and lower speed is obtained as the dial is turned towards the
number 1. to ensure operator control, the tool should always be turned “ON” with the speed adjust-
ment dial in the number 1 position.
Continuous operation of the tool at low speeds for a long time will cause the motor to become
overheated, possibly resulting in malfunction or tool failure. to cool the motor, occasionally run the
tool at high RPm under no load for short periods of time allowing the tool’s fan to cool the motor. be
careful not to obstruct the air vents located in the forward gear housing or in the rear handle, near
the switch trigger.
the speed adjustment dial can only be rotated as far back as the number 1 or forward to the
number 6. dO NOt attempt forcing the dial beyond the numbers 1 or 6, or the speed adjustment
dial will be damaged and no longer function.
POlISHING OPERATION
always wear safety glasses with side shields or a full face shield during tool operation.
Never switch on the tool when it is contacting the work piece or possible injury to the operator or
damaging the work piece may occur.
Hold the tool firmly using both handles. With the speed adjustment dial set at “1” turn the tool on
and lightly apply the rotating foam pad to the work surface. allow the tool to operate freely using
only the tool’s weight as pressure applied to the work surface.
maintain the foam pad at a angle of about 15 degrees to the work surface. NEVER uSE tHE POl-
ISHING Pad flat tO tHE WORK SuRfaCE. use a long sweeping motion, back and forth, while
slowly advancing along the surface being polished. to avoid “burning” the surface or causing finish
swirls, use a low speed and do not hold the tool in one spot or use circular or spiral like patterns.
