CAUTION: Ensure rear handle is locked into one of the three locations before turning tool on to prevent loss of control, damage to the machine, and bodily injury.

USING A DISC SANDER

1.CAUTION: Secure work to prevent it from moving during the sanding operation. Friction between the sanding disc and work will try to spin work away from sander and may cause bodily injury.

2.CAUTION: WEAR SAFETY GLASSES AND DUST MASK.

3.Hold sander firmly by the rear and auxiliary handles, making sure sanding disc is clear of work and foreign objects. Start sander and lower so that sanding disc is FLAT on work surface, Fig. 6.

4.Move sander in long sweeping overlapping strokes as you go back and forth. Do not move sander in a circular motion or stay in one spot too long as this will produce swirls and an uneven finish. The weight of the sander applies sufficient pressure for fast stock removal. Additional pressure will only slow the sander down and decrease removal of stock.

5.LIFT SANDER FROM WORK BEFORE TURNING OFF MOTOR.

6.Always be sure motor has stopped before setting sander down.

SANDING TIPS

For rough sanding and quick stock removal, use a coarse grit sanding disc. For a fine finish, use a medium grit disc, followed by a fine grit disc. Do not go directly from a coarse grit to a fine grit, as it is difficult to remove marks left by the coarse grit disc.

USING A DISC GRINDER

Be certain wheel guard and auxiliary handle are installed.

Firmly grip the auxiliary handle and motor housing as shown in Fig. 7. Lift up rear of motor housing so only the front section of grinding wheel contacts the work. Use light pressure. Always lift the grinder

off work before starting orFig. 7 stopping motor. The arrow on
