- The DRIVE REV valve (F2) [MAR]
- The DUMP valve (F3) [DV]
- The DRIVEHI/LO valve (F4) [HI/LO]
- The DRIVE BRAKE valve (F5) [EVF]
- The MAST valve (F7) [DM]
- The JIB LOWERING valve (F6) [DB]
F1,F2,F3,F5,F6 & F7 : ATO quick acting fuses 1 A.
F4 : ATO quick acting fuse 2 A.

Electronic board potentiometers
setting.
The potentiometers used on the electronic
board are single turn trimmers. Do not
attempt to turn the wiper setting screw more
than the allowed mechanical rotation. Use a
screw driver of proper dimension.
Description
The potentiometers (P1) (P2) (P3) enable the
adjustments of the correct sequencing delays for a
proper operation of the drive function.
Start sequence : When the controller is activated to
perform a drive function (DRIVE SPEED selector
positioned on HIGH speed (
)), the work platform
starts driving in TORQUE speed and switches
automatically to HIGH speed. The time delay for the
work platform to switch to HI speed can be adjusted
by means of the potentiometer (P1).
Soft start / Stop Sequence : When the controller is
slowly activated to perform a drive function (DRIVE
SPEED selector positioned on HIGH speed (
)),
the work platform starts in TORQUE speed and should
only switch to HI speed when the acceleration input
value (from the controller potentiometer) has reached
about 70% of its maximum course. With the platform
driving in HI speed, the platform should switch to
TORQUE speed when the acceleration input value
(from the controller potentiometer) falls just under
40% when slowly returning the controller to neutral.
The speed change threshold can be adjusted by
means of the potentiometer (P2).
NOTE
The differential acceleration input value for
speed changing (from HI to TORQUE speed)
is a fixed value (about 30%).
