ELECTRIC POWER STEERING SYSTEM
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
daily inspection and maintenance.
This chapter also provides important information to
safely use EPS system. If you encounter any
problem during operation or maintenance, please
feel free to consult your local dealer.
ADVANTAGES OF EPS SYSTEM:
1) High efficiency. Traditional hydraulic power
steering system is connected by mechanical
and hydraulic, and it is of low efficiency, usually
only 60%-70%. However, EPS system is
connected by mechanical and electric motor
and it is much high efficiency with up to 90%.
2) Less energy consumption. In practical driving
process of UTV, time in steering condition is
only 5% among the total travelling time. As to
hydraulic power steering system, as long as
the engine is running, the hydraulic pump is
always in working
consumption will increase 4%-6%. However,
EPS system starts the motor, only when it
needs steering, to generate power without
increasing fuel consumption.
3) The power characteristics of EPS system can
be controlled by software, so that UTV can be
satisfied with power steering characteristics at
various speeds.
4) Feeling comfortable on road. Inside of EPS
system, we use rigid connection, so under
auxiliary of start motor, the impact of road

condition, and fuel
barriers on steering wheel can be greatly
decreased.
5) No pollution to environment. For the traditional
hydraulic power steering system, the hydraulic
circuit has hydraulic hose and fittings inside so
oil leaks may occur, and hydraulic hose is not
recycled, so this is produce pollution to
environment. However, EPS system has not
pollution to environment.
6) When engine does not start, EPS system can
also work as battery, and once sufficient power
generate, steering power can be workable.
IMPORTANT INFORMATION
FOR SAFETY:
UTV you buy is equipped with EPS system, please
read this chapter carefully before operating UTV,
and only you are familiar with and master enough
of EPS system about using methods and
precautions information can you start to drive your
UTV.
Make inspection and maintenance on EPS system
on regular, and ensure the security and reliability
when you use your UTV.

Please carefully read this chapter before
operation or
completely about correct way to operate and
drive the UTV with EPS system, and also
characteristics, functions and limits of UTV.
Doing inspection and maintenance on EPS
system on regular, correct operation and
driving skills will ensure the security and
reliability of UTV.
