transmitter functions.

Boom Controls

• To enable boom controls, the deadman joystick, located at the centre of the transmitter, must be

moved and held either to the left or to the right as indicated.

• Once the deadman has been activated, the EWP functions; bottom boom lift, top boom lift, tele boom

extension and slew (not necessarily in that order), may be operated by pushing down on the

respective joystick and moving it to the desired function.

NOTE: EWP FUNCTIONS WILL NOT

OPERATE UNLESS THE DEADMAN JOYSTICK IS OPERATED

PRIOR TO A FUNCTION JOYSTICK BEING OPERATED.

• For precise operation of EWP functions, move the FAST/SLOW switch to the SLOW position to

reduce the work platform function speeds.

Hydraulic Power Tools (If fitted)

• To operate the hydraulic power tools open the ball valve (ON) located on the base control cover prior

to entering the basket.

• With the DC PUMP/POWER TOOLS switch on the transmitter in the neutral position, connect the

power tools hoses to the quick release couplings located outside the basket.

• Once the tools are connected, move the DC PUMP/POWER TOOLS switch on the transmitter to the

POWER TOOLS position to allow the flow of hydraulic oil to the power tool.

• Adjust the speed of the tools using the needle valve, which is located near the quick release

couplings outside the basket.

Emergency Stop

• To immediately stop the machine, press the STOP button located next to the ENGINE START/STOP

button on the transmitter. This automatically powers down the transmitter.

• To operate machine again, twist the STOP button in the direction as indicated and ensure that the

button springs outwards. Repeat the remote startup procedure as above to activate the remote

control system

Engine Stop/Start

• If work is being carried out in a particular position and the booms do not need to be moved, for a

period of time, the engine may be stopped by pressing the ENGINE START/STOP button. When

required, the engine may be started again by pressing the ENGINE START/STOP button again.

Emergency DC Pump (GROUND transmitter only)

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 and hold the deadman joystick in the direction as indicated.

At the same time engage the desired function joystick in the direction required and switch and hold the

DC PUMP/POWER TOOLS switch to the DC PUMP position.

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.

Stabiliser Controls

NOTE: THE STABILISER LEGS WILL NOT OPERATE UNLESS THE TOP BOOM OF THE WORK

PLATFORM IS STOWED.

WARNING: DEFLATE AIRBAG SUSPENSION (IF FITTED) AND ENGAGE SPRING LOCKOUTS (IF

FITTED) BEFORE ENGAGING STABILISERS.

WARNING: THE WHEELS OF THE VEHICLE MUST BE RAISED CLEAR OF THE GROUND PRIOR

TO OPERATING THE BOOMS. FAILURE TO DO SO WILL RESULT IN THE MACHINE BEING

UNSTABLE, AND DANGEROUS, WHEN THE BOOMS ARE RAISED OR EXTENDED.

To operate the stab legs depress the deadman button, located next to the stabiliser direction control

valve, and, at the same time, push or pull the lever on the stabiliser control valve in the direction

corresponding to the desired motion.

WARNING: ENSURE THAT ALL GREEN L.E.DS (IF FITTED) ON THE ELECTRICAL JUNCTION BOX

NEXT TO THE STABILISER CONTROL VALVE ARE ON BEFORE OPERATING THE WORK

PLATFORM.

Spring Lockout Controls (If fitted)

NOTE: THE SPRING LOCKOUTS WILL NOT OPERATE UNLESS THE TOP BOOM OF THE WORK

PLATFORM IS STOWED.

WARNING: DEFLATE AIRBAG SUSPENSION (IF FITTED) BEFORE ENGAGING SPRING

LOCKOUTS.

To operate the spring lockouts depress the deadman button, located next to the stabiliser direction

control valve, and, at the same time, push or pull the lever on the spring lockouts control valve in the

direction corresponding to the desired motion.

WARNING: WHEN WORK IS COMPLETED, ENSURE THAT ALL STABILISERS AND SPRING

LOCKOUTS ARE IN THE STOWED POSITION. INFLATE AIR BAG SUSPENSION (IF FITTED).

Emergency Stops

In the event of imminent danger, loss of EWP control or a serious oil leak, depress one of the emergency

stop buttons. There are emergency stops located on both of the rear stabiliser legs and another one on

the base control cover of the work platform. Activating an emergency stop will divert all the flow from the

PTO pump back to the hydraulic reservoir and isolate all available flow from the accumulator (if fitted).

Once safe to do so, the emergency stop may be reset by twisting the button in the direction indicated on

it.
