OPERATION
Instructions for Use
WARNING: Always observe the safety
instructions and applicable regulations.
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.
• Apply only a gentle pressure to
the tool. Excessive force does not
speed up drilling but decreases tool
performance and may shorten tool life.
• If the accessory jams, stop the motor
and gently raise the accessory out of
the workpiece before resuming work.
• Always use the safety strap.
• Always use the drill guard.
