Setting Torque for Fastener Tightening
The tool stall torque is determined by the air pressure set on an external Lubro Control Unit (Part Number
16074 - supplied where specified).
Tools are supplied with an Air Pressure Graph which relates the torque output to the air inlet pressure.
Set the torque output as follows:
1. Ensure the tool control system is set for the required rotation.
2. For Manual two speed tools (Part number *****.XMTS) select ‘SLOW’ speed.
3. Establish the air pressure required using the Air Pressure Graph.
4. Ensure the drive square is able to free run.
5. With the tool running, adjust the air pressure regulator until the correct pressure is shown on the air pressure
gauge.
IMPORTANT: THE TOOL MUST BE FREE RUNNING WHILE ADJUSTING THE AIR PRESSURE TO
GIVE THE CORRECT SETTING.
WHILE THE TOOL IS FREE RUNNING CHECK THAT LUBRO CONTROL UNIT IS
SUPPLYING APPROXIMATELY SIX DROPS OF OIL PER MINUTE.
Setting Torque for Fastener Loosening
1. Ensure that the tool control system is set for the required rotation.
2. Establish maximum air pressure from the associated Air Pressure Graph or tool label.
3. Adjust the pressure regulator until the correct pressure is achieved.
WARNING: EXCEEDING THE MAXIMUM AIR PRESSURE WILL CAUSE OVERLOADING
AND MAY LEAD TO SERIOUS DAMAGE.
WARNING:
CHANGING THE AIR PRESSURE AFTER SETTING THE PRESSURE
REGULATOR WILL CHANGE THE STALL TORQUE VALUE.
