Troubleshooting
A warning or a fault occurs during the start sequence
The start sequence timers are adjustable. Refer to Start-procedure Timers on page 219 for information.
Refer to
Start the pump on page 61 for a description of the start sequence and problems that can occur.
The pump makes noise during operation
If air is in the hydraulic system, the pump can be noisy during operation.
1. Use a 13-mm socket or wrench to tighten the hose clamps on the suction hose that goes from the hydraulic
fluid tank to the bottom of the hydraulic pump.
2. Torque the hose clamps to a maximum of 29 N∙m (22 lbf ∙ ft).
If the pump is still noisy after tightening the hose clamps, contact a Hypertherm Technical Service Associate for
information and support.
