Maintenance
IMPORTANT:
Check oil level regularly
Use only good quality hydraulic fluid.
Do NOT
use brake fluid, transmission fluid,
turbine oil, motor oil, alcohol, glycerine etc. Use of anything other than good quality
hydraulic oil will void warranty and damage the pump, hose, and application. We
recommend Durapac Hydraulic Oil or equivalent
Equipment must only be serviced by a qualified hydraulic technician. For repair service,
contact your local Durapac authorised service centre
Tighten connections as needed. Use non-hardening pipe thread compound when
servicing connections
Dirt, sand, etc. will quickly ruin any hydraulic system. Ensure that couplings are clean and
free of foreign matter. After each use, clean couplings and attach dust caps.
Maintenance is required when wear or leakage is noticed. Periodically inspect all
components to detect any problem that may require service and maintenance.
