GENERAL SAFETY RULES

SAVE THESE SAFETY INSTRUCTIONS.
For multiple hazards, read and understand the safety instructions before installing, operating, repairing,
maintaining, changing accessories on, or working near the assembly power tool for threaded fasteners.
Failure to do so can result in serious bodily injury.

effectiveness of safety measures and increase the risks to the operator.

WORK AREA
• Keep the work area clean and well lit. Cluttered benches and dark areas increase the risks of
accidents.

improper use and cause injury.
