OPERATION
Instructions for Use
WARNING: To reduce the risk
of serious personal injury, turn
tool off and disconnect tool from
power source before making any
adjustments or removing/installing
attachments or accessories.
WARNING:
• Always observe the safety instructions
and applicable regulations.
• To reduce the risk of personal
injury, ALWAYS ensure workpiece
is anchored or clamped firmly.
If drilling thin material, use a wood
"back-up" block to prevent damage to
the material.
• To reduce the risk of personal
injury, always operate the tool
with the side handle properly
installed. Failure to do so may result
in the side handle slipping during tool
operation and subsequent loss of
control. Hold tool with both hands to
maximize control.
• Do not attempt to tighten or loosen
drill bits (or any other accessory) by
gripping the front part of the chuck
and turning the tool on. Damage to
the chuck and personal injury may
occur.
• Burn Hazard. ALWAYS wear gloves
when changing bits. Accessible metal
parts on the tool and bits may get
extremely hot during operation. Small
bits of broken material may damage
bare hands.
Proper Hand Position (fi g. 6)
WARNING: To reduce the risk of
serious personal injury, ALWAYS use
proper hand position as shown.
WARNING: To reduce the risk of
serious personal injury, ALWAYS hold

To insert a drill bit or other accessory, follow the
steps listed below.
1. Grasp the rear half of the chuck with one hand
and use your other hand to rotate the front half

(19 mm) into the chuck and tighten securely
by holding the rear half of the chuck and
rotating the front portion in the clockwise
direction. When the chuck is nearly tightened,
you will hear a clicking sound. After 4–6 clicks,
the chuck is securely tightened around the
accessory.
3. To release the accessory, repeat step 1 listed
above.

drill bits (or any other accessory) by
gripping the front part of the chuck
and turning the tool on. Damage to the
