4.4 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 switch located on the front of the joystick.
3) Use the Drive Speed selector on the platform control station to determine speed.
Low Drive (Tortoise) - gives low speed and low engine revs.
High Drive (Hare) - gives high speed and high engine revs.
HG Drive (High Gradeability) - gives low speed, high engine revs and high gradeability.
N.B. High Drive (Hare) is only available when the booms are in the stowed position. The HR21
Hybrid will default to Low Drive speed whenever the booms are elevated.
If the machine is driven on slopes exceeding 10
0
it automatically reverts to 4WD (Low speed)
until the joystick is released.
Also, the machine has an additional tilt sensor that monitors its inclination whilst driving. If it is
driven on slopes exceeding 10
0
the drive speed will automatically revert to HG Drive. To return
the machine to High Drive, drive on to level ground (<10
0
) then release and reactivate the
joystick or footswitch.
4) Select drive joystick from the platform control box.
A. Up for FORWARD
B. Down for REVERSE
Steering is controlled by the rocker-switch button on the top of the joystick
C. Left for STEER LEFT
D. Right for STEER RIGHT
The driving horn is activated by the button on the front of the joystick and there is also a
separate horn button on the platform controls for use when the drive and boom controls are
switched off.
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 Drive Speed
selector is in the High Drive (Hare) 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 four-degree working limit. In normal operation the
drive is therefore unaffected when driven onto a slope in excess of four degrees, until the booms
are raised, whereupon the drive would be disabled and the tilt alarm sounds continuously.
8) Under no circumstances should any Height Rider 21 Hybrid series machine be driven on
slopes exceeding the gradeability in the general specification
