Perfomance Tool M670 Owner'S Manual Download Page 3

Oil tool before each use. 4 to 5 drops of a good grade Air Tool Oil placed in the 

air inlet is sufficient. Use proper air pressure and CFM rating listed for this tool.

Drain water from hoses and compressor tank. Water in the air supply line will 

cause gumming and loss of power. Clean the air filter on the supply line and 

flush the tool with gum solvent or a 50/50 mix of air tool oil and kerosene. It 

may be necessary to disassemble the tool to properly clean and re-lubricate.

AIR SOURCE

Clean air of correct air pressure is recommended for the power supply for this 

tool. A maximum of 90 PSI at the tool is recommended for most air tools of this 

class. Check specifications section for recommended pressure. (Depending on 

length of air hose and other circumstances, air pressure at compressor may need 

to be increased to 100 PSI to ensure 90 PSI at the tool.)

Water in the air hose and compressor tank contributes to reduced performance 

and damage of the air tool. Drain the air tank and filters before each use and as 

necessary to keep the air supply dry.

AIR RATCHET SAFETY

1. This air ratchet is designed to speed productivity, not for high torque 

applications such as head bolts, lug nuts, etc. DO NOT USE THIS RATCHET 

UNDER POWER TO BREAK FASTENERS LOOSE. Loosen fasteners by 

hand without depressing throttle. Once loose, depress throttle to speed 

fasteners in or out. Always perform final torque tightening by hand.

2. Use only impact sockets designed for impact wrenches.

3. This ratchet is rated to 1/2" USS bolt size. Rating will decrease for 

U-Bolts, Long Cap Screws, Spring Fasteners and rusted or 

corroded fasteners. All of these factors absorb power and reduce 

torque capability.

4. Always use approved eye and ear protection when using air powered 

tools. If raising dust/debris, wear a suitable mask. Do not wear loose 

clothing or jewelry.

5. Always operate tool a safe distance from yourself and others in the work area. 

Keep footing and balance at all times.

6. Make sure work piece is secure to allow safe operation of the tool with both 

hands. Do not hold the work piece in your hand, lap or against any part of 

your body.

7. Make sure trigger is in the “off” position before connecting or disconnecting 

the tool from air source. Disconnect tool from air source before changing 

accessories, performing service and when not in use.

8. Follow air source manufacturer’s directions for connection of 

regulators, filters and other accessories to air source. Do not install 

quick couplers directly at tool air inlet. This causes inlet failure due 

to excess weight and vibration. Use a whip hose between tool and 

quick couplers.

9. 

DO NOT OVERLOAD! 

Do not force tool. Match tool capacity to work load 

requirement. Use tool within its rated capacity and only for its designated 

purpose. Overloading air tools will cause premature wear and/or permanent 

damage of internal and external drive parts and will void warranty.

10. Inspect hoses and fittings for wear and damage prior to using tool. Do not 

carry or drag tool by the air hose. Keep air hose free from obstruction, twisting 

and binding.Carry the pneumatic driving tool at the workplace using only the 

handle, and never with the trigger actuated.

Take conditions at the workplace into account. Fasteners can penetrate thin work 

pieces or slip off corners and edges of workplaces, and thus put people at risk.

For personal safety, use protective equipment such ad hearing and eye protection.

IMPORTANT: DO NOT

 direct the adjustable vent hole to the operator or other 

person or animals during the use.

Hose length over 25' causes loss in line pressure. Increase hose I.D. or increase 

compressor pressure to compensate for the pressure loss. Use an in-line pressure 

regulator with gauge if air inlet pressure is critical.
