The speed/direction control is for selecting forward
or reverse movement and the travel speed of the lift
truck. The control is spring loaded and should re-
turn to the off position when the control is released.
The control can be operated by either hand. The op-
erator controls the speed and direction of travel by
rotating the control in the desired direction. Maxi-
mum rotation of the control causes maximum
travel speed. To stop or change direction, the opera-
tor rotates the control in the opposite direction. The
lift truck will come to a stop. If the speed/direction
control is not released when the lift truck stops, it
will accelerate in the opposite direction. Changing
direction with the speed/direction control is called
plugging. Arrows on the control indicate the direc-
tion of travel.
WARNING
The traction reverse button causes rapid accelera-
tion and should not be used for changing direc-
tion.
Check the operation of the traction reverse button.
The traction reverse button is on the end of the con-
trol handle. When the button is pushed, the lift
truck will move away from the operator (forks
first). When the button is no longer pushed, the
traction motor will be turned off. The traction mo-
tor will not move the lift truck in the direction of
the control handle until the control is reset. To re-
set, move the speed/direction control to the neutral
position.
Gauges, Horn, Fuses
Check that all the instruments and controls oper-
ate as described in the Operating Manual. The
Operating Manual is located in the container on
the MDU cover. This is a permanent reference and
must be available for use at all times.
Check the operation of the gauges and horn.
If the truck is equipped with a multifunction dis-
play indicator (MDI), the battery indicator has a 4
LED display. As the battery's state of charge de-
creases, successive LEDs turn off. When the bat-
tery reaches 70% discharge, the horn will sound
twice when the lift button is selected. At 80% dis-
charge, the bottom LED will flash indicating
empty. The battery must be charged. Continued op-
eration with the LED flashing can damage the bat-
tery, motors, or the contactors. This unit also indi-
cates lift interrupt. Lift interrupt prevents the lift
pump from operating when the battery is 80% dis-
charged. The system will automatically reset when
a charged battery is connected.
The hourmeter on the combination battery indica-
tor/hourmeter will continually display the total op-
eration hours.
NOTE:
Periodic maintenance recommendations are
based on either the operating hours, as recorded by
the hourmeter, or the time passed, as recorded by
the calendar, whichever comes first.
There are two control fuses located in a fuse block
mounted to the control panel and a power fuse
mounted to standoffs on the control panel. The con-
trol panel is located in the MDU compartment. Re-
move the MDU compartment cover to check the
fuses. Check that the fuses are the correct amper-
age and are not blown. Some types of fuses must be
checked with an ohmmeter. Replace a bad fuse
with a fuse of the correct rating. NEVER use a fuse
with a higher rating.
