Δ
THIS DOUBLE PUMP LONG RAM IS DESIGNED FOR LIFTING PURPOSE
ONLY. NOT FOR SUPPORTING LOADS.

operate pump handle rapidly several times.
TO RAISE LOAD
Close release valve by turning handle COUNTERCLOCKWISE very slowly. The
speed of lowering the load is controlled by how much you turn the handle.
MAINTENANCE
IMPORTANT: Do not use brake fluid or jack oil in the hydraulic system. If oil is
needed, use an anti-wear hydraulic oil with a viscosity grade of 150 SUS at 100°F,
(ISO 32@40°C), or a non-synthetic transmission fluid.
Avoid mixing different grades/types of oil DO NOT use brake fluid, alcohol,
glycerin, detergent motor oil or dirty oil. Improper fluid can cause internal damage
to long ram.
When adding oil, be VERY CAREFUL, not to permit dirt or foreign matter to get into
the system. Check ram & plunger every 3 months for any signs of rust or
corrosion. Clean as needed and wipe with an oily cloth. When not using the long
ram, always leave the shop crane in fully lowered postion.
