MAINTENANCE
WARNING
To raise load
Close release valve by turning handle clockwise to a snug-tight position (Do not overtighten).
To lower load
Open release valve by turning handle counterclockwise very slowly. The speed of lowering the load is controlled
by how much you turn the handle.
Note :
Front legs must always be locked in down position before applying load and/or raising boom. Boom must be in
fully lowered position before raising legs. Legs must never be raised when crane is carrying load. Legs must be
locked in place when raise.
It is possible that air has got into the hydraulic system, causing poor lifting performance. Purge any air from the
system by fully opening release valve (turn handle counterclockwise), then while holding the boom down, operate
pump handle rapidly several times.
Failure to follow these instructions could result in loss of load and/or personal injury or damage to property.
• Visual inspection must be made before each use of the crane, checking for cracks, cracked welds and missing
and/or damaged parts. Any crane that appears to be damaged in any way must be removed from service imme-
diatly.
• Store crane with boom in fully lowered position and hydraulic ram valve closed when not in use. This will prevent
machined surfaces from exposure. Keep all moving parts clean and well lubricated.
• This shop crane is designed for lifting purposes only.
• Not designed for supporting loads.
• Do not load beyond it’s rated capacity.
• Do not overload. Overloading could cause damage or failure of the engine crane.
• Never use the crane on an uneven fl oor surface as this could result in the crane tipping 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 subsituted for inferior types.
• Before each use ensure that all nuts and bolts are correctly fi tted and tight..
• Never exceed the safe working loads indicated on the jib.
