VARIABLE SPEED

The variable speed trigger switch permits speed control. The farther the trigger switch is depressed, the higher the speed of the hammerdrill.

NOTE: Use lower speeds for starting holes without a centerpunch, drilling in metal, plastics or ceramics, or driving screws. Higher speeds are better for drilling in wood and composition board and for using abrasive and polishing accessories.

REVERSING LEVER

The reversing lever is used to reverse the hammerdrill for backing out screws or jammed bits. It is located above the trigger, shown in Figure 2. To reverse the hammerdrill, turn it off and push the reversing lever to the left (when viewed from the chuck end).

To position the lever for forward operation, turn the hammerdrill off and push the lever to the right (when viewed from the chuck end).

High/Low Speed Operation (Fig. 3)

The two speed gear drive in the dual range hammerdrill permits effective operation over an extended range of applications with greater selection of accessories.

For LOW SPEED operation, the shift knob located on the underside of the hammerdrill should be rotated so the low speed setting is toward the front of the tool.

For HIGH SPEED operation, the shift knob should be rotated so the high speed setting is toward the front of the tool.

The gear train has been designed for shifting only when the unit is off. It may be necessary however, to rotate the chuck slightly by hand to align the gears while turning the shift knob.

NOTICE: DO NOT ATTEMPT TO CHANGE SPEEDS by turning the shift knob when the tool is running. Doing so will damage the gear train.
