RIDGID R8411511 manual Reversible, TWO-SPEED Gear Train, TWO Speed Gear Train HI-LO, Rotation

OPERATION

This drill has an electric brake. When the trigger switch is released, the chuck stops turning. When the brake is functioning properly, sparks will be visible through the vent slots on the housing. This is normal and is the action of the brake.

NOTE: You might hear a whistling or ringing noise from the switch during use. Do not be concerned, this is a normal part of the switch function.

REVERSIBLE

See Figure 4.

This tool has the feature of being reversible. The direction of rotation is controlled by a selector located above the switch trigger. With the drill held in normal operating position, the di- rection of rotation selector should be positioned to the left of the switch for drilling. The drilling direction is reversed when the selector is to the right of the switch. When the selector is in center position, the switch trigger is locked.

CAUTION:

To prevent gear damage, always allow chuck to come to a complete stop before changing the direction of rotation or the two speed gear train (hi-lo).

To stop, release switch trigger and allow the chuck to come to a complete stop.

TWO-SPEED GEAR TRAIN

See Figure 7.

The drill has a two-speed gear train designed for drilling or driving at LO (1) or HI (2) speeds. A slide switch is located on top of your drill to select either LO (1) or HI (2) speed. When using drill in the LO (1) speed range, speed will decrease and unit will have more power and torque. When using drill in the HI (2) speed range, speed will increase and unit will have less power and torque. Use LO (1) speed for high power and torque applications and HI (2) speed for fast drilling or driving applications.

AUXILIARY HANDLE

See Figure 8.

An auxiliary handle is packed with the drill for ease of op- eration and to help prevent loss of control.

To use the auxiliary handle:

nOpen the clamping ring by turning the handle counter- clockwise.

nSlide the ring of the auxiliary handle onto the spindle collar of the machine.

nTighten the auxiliary handle at the desired angle by turn- ing the handle clockwise.
