Lubrication

Check the oil level annually by removing

the oil plug found on the top of the pump

housing. When changing or adding oil, fill

the tank through the oil plug screw hole to

80% capacity with hydraulic jack oil, about

2” deep in pump housing, see Figure 3.

Do not use any other type of oil.

There is one grease fitting (#55B in the

breakdown) located on the table.

Lubricate this point on a semi-annual basis.

Fig. 3

Wheel bearings are sealed and require no lubrication. Crank Shaft features oil light

bushings that also require no lubrication. Lightly oil all moving parts.

relief valve, flush out hydraulic system as follows:

Pump handle quickly, raising pallet truck to full extent and then quickly release pumping

action.
