PTW Series Pneumatic Torque Wrench
3 ASSEMBLY AND ADJUSTMENT
The air source must be capable of at least 50 CFM
(85 CMH) at 100 psi (6.9 bar). A minimum hose size
of 1/2 inch (13 mm) must be used. The tool must be
calibrated with the Filter/Regulator/Lubricator (FRL)
that is being used. The PTW equipment (including
tool and FRL) is to be used with an air supply that
is regulated and/or limited to 120 psi (8.3 bar)
maximum.
1. Check the air lubricator oil level and fill if needed.
Only use SAE 10 or lighter clean, nondetergent
oil. Remove the cap and add oil if needed.
2. Turn the drip rate adjustment knob to adjust the
drip rate. The drip rate can be viewed through the
clear adjustment knob. The drip rate should be
checked while the tool is operating. Set the drip
rate to between 4 and 6 drops per minute.
