DRIVING CONTROLS
DO NOT OPERATE THE NIFTYLIFT WHILST ELEVATED UNLESS ON A FIRM,
LEVEL SURFACE FREE FROM ANY POSSIBLE OBSTRUCTIONS OR HAZARDS
BOTH AT GROUND LEVEL AND OVERHEAD.
1)
Check proposed route for possible hazards, obstructions and personnel.
2)
Depress footswitch located on platform floor.
3)
Set the
speed
selector
switch on the platform control station as required.
Tortoise
(Low Speed) - gives low speed and low engine revs.
Off-road
(High Gradeability) - gives low speed and high engine revs.
Hare
(High Speed) - gives high speed and high engine revs.
Note: High Drive Speed (Hare) is only available when the booms are in the stowed position.
The
HR21 will default to Elevated Drive speed whenever the booms are elevated.
At this
point
Off-road
or
Tortoise
can be selected to determine the most appropriate mode for the
current terrain.
If the machine is driven using High Drive Speed (Hare) on slopes exceeding 10
0
it automatically
reverts to
Off-road
speed (High Gradeability). To return the machine to High Drive Speed, drive
on to level ground (<10
0
) then release and reactivate the joystick or footswitch.
4)
Select drive joystick from the platform control panel.
Push forward for
FORWARD DRIVE
Pull backwards for
REVERSE DRIVE
Steering is controlled by the rocker-switch button on the top of the joystick
Left for
STEER LEFT
Right for
STEER RIGHT
The driving horn is activated by a button on the platform controls (Refer to Section 4.3.1).
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.
When driving with the booms fully stowed, the Tilt Sensor is bypassed to allow the Niftylift to be driven
in areas where the slope exceeds the allowable inclination limit. In normal operation the drive is
therefore unaffected when driven onto a slope in excess of this limit, until the booms are raised,
whereupon the drive is disabled and the tilt alarm sounds continuously.
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 THEIR STOWED POSITION
AND RE-POSITION BASE ON FIRM, LEVEL GROUND.
IF ALARM SOUNDS - DESCEND IMMEDIATELY AND RE-LEVEL MACHINE BASE.
