Electronic Power Steering System
8-1
INTRODUCTION
Our UTV is equipped with Electric Power
Steering System (EPS). To keep reliability of
EPS during operation, please correctly use
EPS system according to the following
descriptions and keep up with daily inspections
and maintenance.
This
chapter
also
provides
important
information to safely use the EPS system. If
you encounter any problems during operation
or maintenance, please consult your local
dealer.
ADVANTAGES OF EPS SYSTEM:
1) High efficiency. Traditional hydraulic power
steering
systems
are
connected
by
mechanical and hydraulic systems and are
of low efficiencies; usually 60%-70%.
However,
Hisun’s
EPS
system
is
connected by a mechanical and electric
motor and it has a much higher efficiency
of up to 90%.
2)
Hisun’s EPS system starts the motor only
when it needs to generate power without
increasing fuel consumption.
3)
The power of Hisun’s EPS system is
controlled by software, so that the UTV can
be operated with power steering at various
speeds.
4)
Hisun’s EPS system, uses a rigid
connection system, so the impact of road
conditions on steering wheel is greatly
decreased.
5) No pollution to environment. For the
traditional hydraulic power steering system,
the hydraulic circuit has hydraulic hose and
fittings inside the system so oil leaks may
occur, and hydraulic hoses are not recyclable.
This system type can produce pollution to the
environment. However,
Hisun’s EPS system does not cause pollution
to the environment.
6) If the engine does not start, the EPS system
can also work off the battery, and once
sufficient power is generated, the power
steering system is functionable.
IMPORTANT INFORMATION
FOR SAFETY:
This UTV is equipped with EPS system, please
read this chapter carefully before operating the
UTV, and only when you are familiar with and
master the EPS system methods and precautions.
Make inspections of the EPS system at regular
intervals to ensure the security and reliability of
your UTV.
Please carefully read this chapter before
operating or driving and understand the
correct ways to operate and drive the UTV
with the EPS system, and also characteristics,
functions and limits of UTV. Do inspections
and maintenance on the EPS system at
regular intervals. Correct operation and driving
skills will ensure the security and reliability of
UTV.
To make sure your EPS system will be useful
for a long time please follow the methods for
maintenance in this chapter.
