3. With the cradle lowered, rectify the problem by lubricating, straightening and/or
realigning the mechanical components as required. If the mast is bent, you may
need to contact your agent for support.
4. Close the door and run the machine through several complete lift/lower cycles with
no bin in the cradle, to check that the problem has been properly resolved.
5.3.2 Cradle jams while lowering
If the cradle jams on the way down, or has jammed on the way up but will not come down, it
may be due to a hydraulic, electrical, or mechanical fault.
5.3.2.1 Hydraulic or electrical fault
When the LOWER button is pressed, the lowering valve should emit a ‘click’ sound as it
opens. If it does not, the problem may be either a hydraulic or electrical fault.
1. Manually disable the safety door interlock as per Section 5.8.3.1 , and open the door.
2. Attach lifting slings to a forklift or hoist, and carefully take the weight of the cradle.
Never place any part of your body underneath the cradle unless it is securely supported.
3. Remove the powerpack cover.
4. Unscrew the fitting attaching the steel hydraulic pipe to the powerpack, and hold the
end of the pipe over a container with a capacity of at least 2 litres.
5. Lower the cradle slowly with the forklift, collecting the oil in the container.
6. Once the cradle is fully lowered, remove the bin.
7. Reconnect the hydraulic pipe and fitting, and refill the oil tank.
8. Check that the lowering valve coil is receiving an electrical signal. An LED lamp
should glow on the coil plug when the LOWER button is pressed. If it does not, check
the wiring.
9. If the coil is receiving an electrical signal but not opening, it may need to be cleaned:
a. Remove the coil from the valve stem.
b. Unscrew the lowering valve cartridge.
c. Clean the cartridge with compressed air.
d. Replace the lowering valve components by reversing this procedure.
10. Replace the lowering valve, and test to see if the cradle lowers correctly.
11. Re-enable the safety door interlock as per Section 5.8.3.1 , and run the machine
through several complete lift/lower cycles with no bin in the cradle, to check that the
problem has been properly resolved. If the lowering valve is still not operating
correctly, it may need to be replaced
– contact your agent.
5.3.2.2 Mechanical fault
If the lowering valve is operating correctly (emits a ‘click’ sound when the LOWER button is
pressed), the problem may be a mechanical fault.
1. Manually release the safety door interlock as per Section 5.8.3.1 , and open the door.
2. Provide support for the cradle, either with a structure underneath or with a sling
holding it to the top of the main frame. Allow for it to fall no more than 50mm.
Never place any part of your body underneath the cradle unless it is securely supported.
