4.4 Trouble Shooting
The following chart can be used as a guide to correct any problem you may
experience with the tool.
To determine the problem in operation of the weld shear always check that the
hydraulic power source is supplying the correct hydraulic flow and pressure to
the tool as listed in the table. Be sure you are using an accurate flow meter.
Check the flow with the hydraulic fluid temperature at least 80° F/27° C.
NOTE: Stop and depressurize the hydraulic system before connecting or
disconnecting a tool. Failure to follow these instructions can lead to severe
personal injury. Read and follow the instructions in this manual for the proper
way to connect and disconnect tools from the hydraulic systems.
