4)
Select drive joystick from the platform control box.
A. Up for FORWARD
B. Down for REVERSE
C. Left for STEER LEFT
D. Right for STEER RIGHT
5)
All control levers give a fully proportional response therefore the more the lever is moved away from the centre (OFF) position the faster the
function will become.
6)
Maximum drive speed is only attainable when all booms are fully stowed and the HI/LO selector is in the HI position.
7)
When driving with the booms fully stowed, the Tilt Alarm is bypassed to allow the Niftylift to be driven in areas where the slope exceeds the
five-degree working limit. In normal operation the drive is therefore unaffected when driven onto a slope in excess of five degrees, until the
booms are raised, whereupon the drive would be disabled and the tilt alarm sounds continuously.
8)
Under no circumstances should any Niftylift SP series machine be driven on slopes exceeding 25%, with the booms fully stowed.
ALL NIFTYLIFTS ARE FITTED WITH A TILT ALARM - PRE-SET IN THE FACTORY. ONCE ENERGISED, THE NIFTYLIFT WILL LOSE ALL
POWER TO DRIVE FUNCTIONS AND A LOUD AUDIBLE ALARM WILL BE ACTIVATED.
TO DE-ACTIVATE, LOWER THE BOOMS FULLY TO THE STOWED POSITION AND RE-POSITION BASE ON FIRM, LEVEL GROUND.
IF ALARM SOUNDS - DESCEND IMMEDIATELY AND RE-LEVEL MACHINE BASE.

EMERGENCY CONTROLS
IN THE EVENT OF AN INCAPACITATED OPERATOR
Turn the key switch selector at ground control station to ground (i.e. fully down). Ensure function selector hand valve is turned to Ground position
(i.e. fully down). Manoeuvre the machine using the ground controls as described previously.
IN THE EVENT OF MACHINE FAILURE
If all machine power is lost, the Manual Hand pump can be used to provide the hydraulic power to manoeuvre the machine. Operating the Manual
Hand pump provides flow to the valve block selected at the ground controls. Hence the ground person can give hand pump flow to enable the
Platform operator to move the machine, or control can be taken at the Base as described above, to enable the ground operator to pump and at the
same time, manoeuvre the machine using the Ground hand levers. If initial movement of the machine allows the master alarm to reset, normal
controls will be available.
Note: If the machine is fitted with a cage overload system, and the cage comes into contact with a fixed object whilst operating at height, this would
be detected as an overload condition. All power to the machine controls would be lost, requiring the machine to be recovered using the Manual
Hand Pump. It is sufficient for the cage to be manoeuvred away from the collision point to re-set the cage weigh mechanism, thereby restoring
normal machine operation. The cage could then be brought down using the controls as described previously.
FOLLOWING AN EMERGENCY DESCENT RECOVERY OF THE PLATFORM, FULLY EXTEND AND RETRACT ALL CYLINDERS FROM GROUND
CONTROL STATION BEFORE USING THE MACHINE.
