Auto Shift Controller ASC-100 (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
driving the truck outside of the design parameters,
e.g. selecting the reverse gear when traveling in
excess of 5.1 km/h ( 3.17 mph) in a forward
direction, and vice versa.
The Autoshift controller is mounted on a convenient
position away from excessive heat sources and the
truck’s electrical system is retrofitted. An inductive
speed sensor is mounted on the differential housing
where it will pick up a pulse from a yoke 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.
The Autoshift controller prevents strain and abuse
to the transmission. It also prevents damage to the
half shaft, excessive tire wear and heat to the
transmission.
WARNING
Improper operation or maintenance could result
in injury or death. Do not operate or work on the
lift truck unless you are properly trained. For
safe operation, carefully read and follow this
Operation and Maintenance Manual.
