ADJUSTING THE TORQUE
See Figure 11.
The hammer drill is equipped with an adjustable torque clutch
for driving different types of screws into different materials.
Adjust the torque as necessary. We recommend that you use
carbide-tipped bits and select hammer mode when drilling
in hard materials such as brick, tile, concrete, etc.
n Identify the torque indicator settings located on the
front of the hammer drill.
n Rotate the adjusting ring to the desired setting.
• 1 - 4 For driving small screws
• 5 - 8 For driving screws into soft material
• 9 - 12 For driving screws into soft and hard materials
• 13 - 16 For driving screws in hard wood
• 17 - 21 For driving large screws
• For heavy drilling
• For hammer drilling
CHANGING THE BIT ROTATION
See Figure 12.
The direction of the chuck is controlled by the rotation selec-
tor located above the trigger switch.
n For forward rotation: Move the rotation selector to the
left.
n For reverse rotation: Move the rotation selector to the
right.
NOTE: The hammer drill will not run unless the selector
is pushed fully to the left or right.
