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 jack, 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
The greatest single cause of failure in hydraulic systems is dirt; keep the jack clean and well
lubricated to prevent foreign matter from entering the system. If the jack has been exposed
to rain, snow, sand or grit, it must be cleaned before and after each use.
Maintenance is required when wear or leakage is noticed. Periodically inspect all
components to detect any problem that may require service and maintenance.
