Add Hydraulic Fluid to the Hand Pump
Check the fluid level in the reservoir of the hand pump occasionally by removing
the pump’s reservoir plug and observing the level shown on the dip stick. If the
level is low, add Quaker Quintolubric hydraulic fluid, or equivalent, only.
Difficulty in obtaining or maintaining the pressure required for grip operation
may be caused by low fluid level.
