supply. 

2.  An air pressure of 90 PSI. is required.

MAINTENANCE 

WARNING: Make sure the Impact Wrench is disconnected from its power source before attempting 

any maintenance, cleaning, or inspection.

Maintain your Impact Wrench. It is recommended that the general condition of any tool be examined 
before it is used. Keep your Impact Wrench in good repair by adopting a program of conscientious 
repair and maintenance in accordance with the recommended procedures found in this manual. If any 
abnormal vibrations or noise occurs, turn the Impact Wrench off immediately and have the problem 
corrected before further use. Have necessary repairs made by qualified service personnel. 

·

 

Keep all cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are 
less likely to bind and are easier to control. Keep handles dry, clean, and free from oil and grease.   

·

 

Cleaning. Use only soap and a damp cloth to clean your Impact Wrench. Many household cleaners are 
harmful to plastics and other insulation. Never let liquid get inside the Impact Wrench.
