Using Clutch (Fig. 3)
This tool has an adjustable clutch for driving different types of screws into
different materials. When properly adjusted, the clutch will slip at a preset
torque to prevent driving the screw too deep and to prevent damage to
the screw or tool.
To adjust the clutch, turn the clutch adjusting ring to one of the twenty
positions shown on the adjusting ring.

crease or decrease pressure on the trigger. The further the trigger is pulled,
the greater the speed.
Selecting Hammer or Drill Action
MILWAUKEE Hammer-Drills are designed for two operating modes: drill-
ing with hammering action and drilling only. To set the operating mode,
rotate the Hammer-Drill selector collar to the desired symbol. A drill or
hammer symbol will appear at the top center of the collar to indicate
operating mode.
1. To use the hammer-drilling mode, rotate the selector collar until
the hammer symbol
Apply pressure to the bit to engage the hammering mechanism.
2. To use the drilling only mode, rotate the selector collar until the
drill symbol
NOTE: When using carbide bits, do not use water to settle dust. Do not
attempt to drill through steel reinforcing rods. Both actions will damage
the carbide bits.
Using Control Switch (Fig. 5)
The control switch may be set to three positions: forward, reverse and
lock. Due to a lockout mechanism, the control switch can only be ad-
justed when the ON/OFF switch is not depressed. Always allow the motor
to come to a complete stop before using the control switch.
