7 Operation
7.1 Inspections before use
Make sure that:
• the air supply is correct.
• the air supply is fully unrolled and not kinked, twisted or damaged.
• all couplings and other connections are tight and not damaged or deformed.
• the pneumatic hoses are securely connected and not kinked, twisted or damaged.
• all moving parts of the tool are clean and sufficiently lubricated with a high-quality
lubricating oil (Shell Tellus S2 VX 32).
• the oil level in the oil filter reservoir is between the minimum mark and the maximum
mark.
• the air lubrication knob is set to four drops per 60-90 seconds.
• the reaction arm is placed against a solid reaction point and secured to the tool.
• the socket has the correct size and is secured to the tool.
• all securing clips, securing pins and securing screws are fitted and secured to the air
supply, FRL, the pneumatic hoses, the tool, the reaction arm and the socket.
• all water, if present, is drained from the filter reservoir.
• the pressure gauge does not leak. Signs of leakage are a decrease in the level of
glycerin in the pressure gauge or the pressure gauge filled with lubrication oil.
7.2 Determining the gearbox mode (Dual Speed and Nut Runner)
