• Every six (6) months, grease the electric motor bearings (Figure 6-13). Four shots of grease per
bearing are sufficient.

Hydraulic Filters and Oil
• Monthly, check the in-tank oil filter gauge (Figure 3-15, page 3-16) mounted on the reservoir top.
Change the filter element when the gauge indicates greater than 20 psi during lifting or lowering, or
when the High Filter Pressure Error is displayed on the HMI screen.
• Monthly, check the high-pressure filter indicator (Figure 3-14, page 3-15). Change the filter element
when the indicator shows in the red while the carrier is lifting or lowering.
• Replace the pump case drain spin-on filter when replacing the in-tank return filter
(Figure 3-14, page 3-15) or every six (6) months, whichever occurs first.
Choose the Type of Hydraulic Oil
Use of a high quality hydraulic oil is essential for satisfactory performance and long hydraulic component
life.
Hydraulic oil of a viscosity of 150 to 330 SUS at 100°F (38°C) is recommended. High viscosity (100 or
greater) oil will provide good results under normal temperature conditions, minimize cold-start trouble, and
reduce the length of warmup periods. A high viscosity index helps minimize changes in viscosity with
corresponding changes in temperature. Maximum cold weather startup viscosity should not exceed
5,000 SUS with a pour point of at least 20°F (–7°C) lower than the minimum ambient temperature.
NOTE
Disregard the High Filter Pressure Error when
the oil is cold (less than 70ºF (21ºC)).
