8.0 Maintenance
8.1 Cleaning Release Valve
Over time, the hydraulic pump assembly may
become clogged with debris or air bubbles, and not
function properly.
To clean the release valve and bleed the pump:
1. Pump handle quickly, raising pallet truck to full
extent. While continuing pumping action, pull
lever to down position.
2. When forks reach total down position, valve is
flushed. Repeat if necessary.
8.2 Lubrication
Check oil level annually by removing oil plug found
on top of 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 7. Do not use any
other type of oil.
