WARNING
Do not overload. Overloading could cause damage or failure of the crane. Never ex-
ceed the safe working loads indicated on the jib.
Never use the crane on an uneven floor surface as this could result in the crane tip-
ping over.
Always lock the legs and jib in position before lifting a load.
The nuts and bolts supplied with the crane are all high strength and should not be
substituted for inferior types. Before each use ensure that all nuts and bolts are cor-
rectly fitted and tight.
WARNING: This double pump long ram is designed for lifting purposes only – not for
supporting loads. Do not load beyond its rated capacity.
IMPORTANT: It is possible that air has got into the hydraulic system causing poor
lifting performance. Purge any air from the system by fully opening the release valve
(turn handle counter-clockwise) then while holding the boom down operate the pump
handle rapidly several times.
Note: Before raising the legs to the storage position bolts must be inserted into the
base support and tightened each time. If this procedure is not followed the unit may
fall over.
MAINTENANCE
IMPORTANT: When adding or replacing oil always use high grade hydraulic jack oil.
Avoid mixing different grades/types of oil. Do not use brake fluid, alcohol, glycerine,
detergent motor oil or dirty oil. Improper fluid can cause serious internal damage to
the ram.
When adding oil be very careful not to permit dirt or foreign matter to enter the sys-
tem. Check ram and plunger every 3 months for any signs of rust or corrosion. Clean
as needed and wipe with an oily cloth.
When not using the ram always leave the jib in the fully lowered position.
