Auto Shift Controller ASC-208 (If Equipped)
Product Description
The Autoshift controller is an electrical control
system, specially designed for use on forklift trucks
with internal combustion engines.
Its primary purpose is to prevent the operator from
operating the truck outside of the design parameters,
e.g. selecting the reverse gear when travelling in
excess of 5 km/h (3.11 mph) in a forward direction,
and vice versa.
The Autoshift controller is mounted on a convenient
position away from excessive heat sources and
retrofits into the truck's electrical system. An
inductive speed sensor is mounted on the
transmission case where it will pick up a pulse from
a gear tooth pattern. This pulse is used to monitor
the truck in motion and its travel speed. To enable
the system to change gears smoothly, the shift
points for offset speed are adjustable.
An operator no longer has to change gears with his
hands, therefore he can be more productive.
The Autoshift controller prevents strain and abuse to
the transmission by changing gears up and down
automatically. It also prevents damage to the half
shaft, excessive tire wear and heat to the
transmission.
Features
Product Adaptable To
ASC-208 D(G)60/70S-7 (2 Speed)

Adjustments
Adjustment Switch
• Low-High Shift Point (SW1)
ASC-208 allows you to set the 2 speed Auto Gear
Shift Point, the maximum travel speed at which the
Auto Shift Controller up-shift or down-shift the
transmission automatically according to the vehicle
speed. For adjustment of 2 speed Auto Gear Shift
speed, the SW1 switch is used on the printed circuit
board.
• Direction Inhibit Point (SW2)
Auto Shift allows you to set the Direction Inhibit
Speed, the maximum travel speed at which the
transmission can be reversed. For adjustment of
direction inhibit speed, the SW2 switch is used on
the printed circuit board.
Using a philips screwdriver, turn the SW1
adjustment until the white dot is next to the notch
corresponding to the selected vehicle speed. You
may reset lnhibit Speed to one of ten settings
between a minimum of 3.3km/h(2.05mph) and a
maximum of 6.0km/h(3.75mph) travel speed.
