TRIGGER "ON-OFF" SWITCH

To turn the tool "ON" squeeze the trigger

switch. To turn the tool "OFF", release the

trigger switch, which is spring loaded and will

return to the "OFF" position automatically

(Fig. 1).

To increase switch life, do not turn switch on

and off while tool is under load.

"LOCK-ON" BUTTON

The "Lock-ON" button, located near the trigger

allows for continuous operation at maximum

OPM without

holding the trigger (Fig. 1).

TO LOCK TRIGGER "ON": squeeze trigger,

depress button and release trigger.

TO UNLOCK THE TRIGGER: squeeze trigger

and release it without depressing the "Lock-

ON" button.

If the “Lock-ON” button is

continuously being depressed,

the trigger can not be released.

VARIABLE SPEED DIAL

Your sander is equipped with a variable speed

dial (Fig. 1). The sander's orbital speed can be

prese

t by rotating the dial to any of six

positions from 1 (8000 OPM) to 6 (11000

OPM).

In general,

• Higher-speeds are used to achieve results

more quickly.

• Lower speeds are especially appropriate

when sanding soft materials or thin veneers

to minimize the possibility of over sanding.

The best results will be obtained by sanding a

test sample of the workpiece material and

determining the best combination of sa

nding

speed and sanding sheet (sanding paper).

FRONT HANDLE

Your sander is equipped with a removable

front handle when sanding in tight quarters. To

remove handle, remove screw with 5 mm hex

wrench. Always reinstall handle for normal

operation (Fig. 1).

Depending on the task, you may grip the rear

handle alone, the rear handle and the front

handle, or the rear handle and the top of the

ergonomically contoure

d soft grip motor

housing, which is designed for that purpose.

ABRASIVE SHEETS (SANDPAPER)

Aluminum oxide, silicon carbide, or other

synthetic abrasives are recommended for

power sanding use. Natural abrasives, such as

flint or garnet sheet are too soft for economical

use in power sanding. For best results, use
