TOWING – Gearbox Drive motors with integral hydrostatic brakes. (Not spring applied.)
Towing the Niftylift in case of an emergency.
1) If parked on a slope securely chock all wheels.
2) Remove front cover: locate brake release valve (red, square knob) and turn anti-clockwise.
The wheel motors are now free of the hydraulic circuit.
3) Move the brake override lever (adjacent to the ground controls) to the horizontal position.
Fit the manual hand pump handle and give the hand pump several pumps until pressure is
felt to build. 2WD Only - A visual check of the brake telltale (Located on the Drive Control
Valve) will indicate when the brakes are released. When the indicator knob comes out of the
block, the brakes are 'Off'.
4) The Niftylift can now be towed over short distances - maximum speed 5mph.
5) To re-set the brakes, move the brake override lever back to the normal 'up-right' position.
Note; It may be necessary to cycle the lever more than once to re-set the brakes.
2WD Only - The telltale indicator will return flush into the block.
6) In order to drive the machine once more, the brake release valve will need to be closed, by
turning clockwise. The wheel motors are now re-connected to the hydraulic circuit.
7) If the brake override lever is not re-set manually, the next time the machine is moved
hydraulically, the brakes will automatically re-set themselves. The brake override lever will
however be in the wrong position for emergency operation of the booms, and should be
returned to the normal 'up-right' position as soon as possible.
4.7.3 STORAGE
If being stored for any length of time without use, then the machine should be thoroughly inspected
for the following:-
1) Grease all bearings /slides, worm drives, etc.
2) Check batteries for electrolyte levels, state of charge, damage, dirt, etc. Never leave in a state
of discharge for any length of time. If no use of the platform is intended, an occasional "top-
up" charge of the batteries will serve to equalise their charge level.
3) Leave battery disconnect switch in OFF position to prevent discharge of batteries through
leakage.
4) If machine is to be left on an incline, chock wheels to prevent creep.
5) If machine is to be left out-of-doors or in a hostile environment, cover with suitable
weatherproof media to prevent deterioration.
