NIFTY LIFT
Base Controls
NOTE: THE CONTROLS LOCATED ON THE BASE OF THE MACHINE, EXCLUDING THE BASKET
TRIM CONTROLLER, ARE FOR EMERGENCY USE ONLY.
WARNING: THERE IS TO BE NO PERSON IN THE BASKET WHEN THE BASKET IS BEING
LEVELLED USING THE BASKET TRIM FUNCTION. FAILURE TO FOLLOW THIS WARNING MAY
RESULT IN SERIOUS INJURY.
•
To operate the base controls, located at the base of the machine, the control selector switch located
on the electrical enclosure on the base, must be switched to the base controls position.
•
To operate a function, push the deadman lever, located at the left hand end of the base controls, in
the direction indicated on the sign and then move any of the EWP functions; bottom boom lift, top
boom lift, tele boom extension, slew, and basket trim, to achieve the desired motion.
Emergency Controls and Emergency Basket Retrieval
The Nifty Lift RKT range of Elevating Work Platforms are equipped with different power sources which
may be used to lower the basket and stow the machine in the event of vehicle engine break down.
1: Accumulator (If fitted)
If engine power is lost and cannot be regained, the booms may be brought to the stowed position, or the
basket lowered to the ground, using the reserve of hydraulic fluid in the accumulator. In this situation,
work platform controls may be operated, from either the basket or the base, in the same manner as
when the engine is running. The accumulator, located on the vehicle, is kept charged (i.e. pressurised),
while the vehicle engine is running, during normal operation of the work platform. When charged, it holds
a volume of hydraulic oil, under pressure, adequate to stow the tower. In addition to stowing the tower,
there may be enough oil left to raise the stabiliser legs. This depends on the initial position from which
the booms are stowed.
2: Emergency DC Pump (If fitted)
If engine power is lost, the emergency pump may be used to operate the machine. To operate a boom
function using the emergency pump, move the control lever on the control valve, in the base, that
corresponds to the function and direction required. Then push the deadman lever to the deadman
position and also depress the emergency pump button, located above the deadman lever,
simultaneously.
To operate the stabiliser legs, using the emergency pump, move the stabiliser control lever, on the
control valve, that corresponds to the function and direction required and then push the emergency
pump button.
3: Emergency Hand Pump (If fitted)
If engine power is lost and the emergency pump will not operate, the emergency hand pump may be
used to operate the machine.
•
Ensure that the lever on the side of the hand pump itself is in the “ENGAGE” position, i.e. pointing
towards the base structure.
•
Place the hand pump handle, located on the pedestal, into the socket on the pumping lever at the
end of the hand pump.
•
Move, and hold, the lever corresponding to the desired function and then pump the hand pump using
the extension handle, located on the pedestal.
