ASSEMBLY AND ADJUSTMENTS
WARNING: To reduce the risk of serious personal
injury, turn unit off and remove the battery pack
before making any adjustments or removing/
installing attachments or accessories. An
accidental start‑up can cause injury.
Torque
WARNING: This is a high‑torque drill. To reduce the
risk of serious personal injury, ALWAYS hold tool
firmly with both hands in the proper position for
operation as shown.
Torque is the twisting action the drill produces in regards
to the rotating bit. As the drill bit meets resistance in the
material being drilled, the motor responds by adjusting the
output torque to meet the requirement up to the maximum
capacity of the motor and gear system.
Bracing the Tool (Fig. B)
WARNING: To reduce the risk of serious personal
injury, ALWAYS hold or brace the tool securely in
anticipation of a sudden reaction.
WARNING: To reduce the risk of serious personal
injury, NEVER brace the tool against the battery pack.
With hands in the proper hand position (also refer to Fig. H),
brace the tool as shown in Figure B.
The bit rotates clockwise when the tool is in the forward
position and counterclockwise when the tool is in the
reverse position. Using proper hand position, brace the side
handle
or tool body against a stud for better support.
