Troubleshooting
Echion Operator Manual 810770 133
The pump makes noise during operation
The pump can make unusual noise during operation if air is in the hydraulic system.
1. Use a 10-mm socket or an open-ended wrench to tighten the hose clamp on the suction hose
that goes from the hydraulic fluid tank to the hydraulic pump.
2. Torque the hose clamp to a maximum of 16 N∙m (12 lbf∙ft).
If the pump continues to make noise after the hose clamp is tightened, contact a Hypertherm
Technical Service Associate for information and support.
