Two Year Maintenance
• Replace the hydraulic oil of the unit.
Changing the Hydraulic Oil
The hydraulic oil is the primary medium for transmitting pressure and also must lubricate the
running parts of the pump.
Replace the hydraulic oil at least once a year.
1. Remove top cover and motor assembly and move aside enough to access the inside of the
tank.
2. Using a suitable container and a siphon pump, drain the oil from the tank.
3. Clean the inside of the tank.
4. Remove and clean the suction filter.
5. Install the filter.
6. Check the drained oil. If there are metal particles visible, or if the oil has a grey color. This
can indicate worn out parts in the cylinder or the hydraulic unit.
7. Take care to prevent dirt and water getting inside the oil tank. Replace the cover.
8. Fill with hydraulic oil Tellus #46 BRAND or an equivalent with similar specifications.
9. Replace the oil fill cap.
10. Purge air from the hydraulic system.
