11. Ease of accessibility and replacing of internal parts;
Replacement of parts should only be carried out by appropriately trained and competent persons.
If parts require replacement only replace the complete item such as Boom Switch, Jack Safety Switch,
PCB or Hydraulic valve block.
Do not attempt to open the safety module or replace components soldered to any PCB.
Do not attempt maintenance of hydraulic components i.e. replace seals or internal component.
Only Niftylift original and supplied parts shall be used.
12. Means for easy and safe trouble shooting;
To check the operation of the stabiliser monitoring system
1. Power on the Niftylift and select the base control location.
2. Using the jack duty selector, engage the selected power option and deploy the jacks into contact
with the floor, levelling the spine of the machine.
3. In order to verify the stabiliser monitoring safety circuit it is necessary for someone to operate
and hold the base green button whilst a second operative performs the jack foot switch test.
Manually depress each jack foot switch plunger in turn by reaching inside the outrigger housing
and finding the safety switch. Once depressed, the hydraulic power on the machine will be lost
until the plunger is released. As each switch is manually depressed, operating a boom lever will
not cause the boom to move, the alarm will however not sound, as the booms are still stowed.
4. Return to the ground control location and using the base green button raise the booms to clear
the boom rest and operate the cam switch. (Situated between booms 2 and 3 adjacent to the
knuckle)
