6.1 Inspections before use
Make sure that:
• the oil level in the oil tank is beween the minimum mark and the maximum mark.
• the power supply is correct.
• the power cable is fully unrolled and not kinked, twisted or damaged.
• the remote control cable is fully unrolled and not kinked, twisted or damaged.
• all couplings and other connections are tight and not damaged or deformed.
• the hydraulic hoses are securely connected and not kinked, twisted or damaged.
Inspect the hydraulic hoses for damage with a set pressure of 200 bar (2,900 psi), 400
bar (5,800 psi) and 700 bar (10,000 psi) respectively.
• all moving parts of the tool are clean and sufficiently lubricated with a high-quality
NLGI #2 molybdenum disulfide grease. For subsea applications, HYTORC
recommends Womi lube.
• the square drive and the drive retainer are securely fitted.
• 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
pump unit, the hydraulic hoses, the tool, the reaction arm and the socket.
• all water, if present, is drained from the water separator (pneumatic pump units only).
• 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 hydraulic oil.
