)
Operating Pressure.
WARNING
Try to minimum the danger of overload: Using hydraulic gauge to indicate the working pressure. Hydraulic
gauge is a window to show what happened in the hydraulic system.
WARNING
To replace the worn components with the JHJX’s new components as soon as possible.
CAUTION
Do not subject the components to potential hazard such as fire, sharp surfaces, extreme heat or cold, or
heave impact.
CAUTION
Never attempt to grasp a leaking pressurized hose with your hands. The force of escaping hydraulic fluid
could cause serious injury.
Do not let the hose kink, twist, curl or bend so tightly that oil flow within the hose is blocked or reduced.
Do not use the hose to move attached equipment. Stress can damage the hose, causing personal injury.
WARNING
To avoid personal injuries and equipment damages, do not remove the shroud of the wrench.
Do not modify any component of the wrench. Do not change the relief valve which is inside the swivel
couplings.
CAUTION
The incorrect system connection will cause failure and danger. Before connection, make sure the swivel
couplings being clean. After application, the swivel couplings must be put on the dust caps.
CAUTION
Do not use worn socket and square drive.
CAUTION
Please use the socket of good performance. The quality should be according with the standard of ISO-2725
or ISO-1174 or DIN3129 or DIN3121 or ASME-B107.2/1995.
