AIR SUPPLY  
AIR PRESSURE:  85 PSI (6 kg/cm 2

increase the output of the tool.   Overloading will drastically shorten the life of all internal parts.  
LUBRICATION  
FOR AIR MOTOR :  Supply light Turbine Oil properly through Air Inlet or line lubricator before and after every operations. For example, Mobil 
Turbine Oil #32, Shell Turbine Oil   #32 and/or equivalent.   
FOR GEARS AND BEARINGS:   Supply recommended high - quality grease (e.g., Shell Alvania No. 2, Shell Alvania, Mobilplex 2, Mobilplex 47 
and/or equivalents) properly once every three months and when the tool is overhauled. Over - greasing   will cause dull motion or heating.  
MAINTENANCE  
DRY AND CLEAN AIR:  Drain daily and install filter at or near the take - off point to prevent trouble from foreign matter.  
AIR HOSE AND JOINTS:  Use air hose (the shorter, the better), joints, and other fittings  of good condition and of proper size to avoid pressure drop.  
REGULAR OVERHAUL:  At least once every three months, a regular or periodical overhaul by a competent person is needed for best performance, 
trouble - free operation, and maximum tool life.  
GENUINE P ARTS:  The use of other than genuine AIMCO replacement parts may result in safety hazards, decreased tool performance, and 
increased maintenance, and may invalidate all warranties. Use only Uryu’s genuine spare parts for replacement.  
ATTENTION  
For correct u se of tool, tilted setting of the tool on the job causes irregular stop. Apply the tool to the screw at right angle.  
EXTERNAL TORQUE ADJUSTMENT (AIR SHUT - OFF)
