Warning!
Crush risk. Do not stand between machine and tractor when coupling. Always apply the
brake on the tractor when leaving the cab during all coupling and uncoupling.
The machine may only be coupled to a tractor/trailer with sufficient weight over the front
and rear axle respectively so that steering and brakes are in working order when the
machine is coupled. Use ballast weights as necessary, see the tractor’s instruction
manual. When working with a grapple loader, use the support legs (consider retrofitting if
not mounted).
The temperature of the hydraulic oil must be checked during operation. If the temperature
rises too high, the reason should be located immediately to avoid serious damage.
If the crane’s valve package is to be mounted inside the tractor cab, protection must be
installed to prevent oil at high pressure reaching the operator, e.g. after a hose rupture.
NOTE!
Ensure no-one is inside the risk area when lifting.
Take care with straps and wires when they are removed as they are tensioned very hard.
They can also be very sharp.
The hydraulic system to which the crane is coupled must be unconditionally fitted with
an efficient filter on the return side.
Trouble-free operation presumes the hydraulic system to be in good condition and that
maintenance has been carried out as recommended.
The crane is normally function tested before delivery. The cylinders may therefore
contain some test oil.
Delivery and return hoses must not be coupled to double-acting outlet.
Instead, the return hose shall be coupled to a separate pressure-free return outlet.
