Basic Service Methods - Hisun HS400 Service Manual

BASIC SERVICE METHODS

Most of the procedures in this manual are
straight forward and can be performed by
anyone reasonably competent with tools.
However, consider personal capabilities
carefully before attempting any operation
involving major disassembly.
1. Front, in this manual, riders to the
front of the UTV, The front of any
component is the end closest to the
front the UTV. The left and right
sides refer to the position of the
parts as viewed by the rider sitting
on the seat facing forward.
2. Whenever servicing an engine or
suspension component, secure the
UTV in a safe manner.
3. Tag all similar parts for location and
mark all mating parts for position.
Record the number and thickness
of any shims when removing them.
Identify parts by placing them in
sealed and labeled plastic sandwich
bags.
4. Tag disconnected wires and
connectors with masking tape and a
marking pen. Do not rely on
memory alone.
5. Protect finished surfaces from
physical damage or corrosion. Keep
gasoline and other chemicals off
painted surfaces.
6. Use penetrating oil on frozen or
tight bolts. Avoid using heat where
possible. Heat can warp, melt or
affect the temper of parts. Heat also
damages the finish of paint and
plastics.
General
7. When a part is a press fit or
requires a special tool to remove,
the information or type of tool is
identified in the text. Otherwise, if a
part is difficult to remove or install,
determine the cause before
proceeding.
8. To prevent objects or debris from
falling into the engine, cover all
openings.
9. Read each procedure thoroughly
and compare the illustrations to the
actual components before starting
the procedure.
10. Recommendations are occasionally
made to refer service to a
dealership or specialist. In these
cases, the work can be performed
more economically by the specialist
than by the home mechanic.
11. The term replaces means to discard
a defective part and replace it with a
new part. Overhaul means to
remove, disassemble, inspect,
measure, repair and/or replace
parts as required to recondition an
assembly.
12. Some operations require using a
hydraulic press. If a press is not
available, have these operations
performed by a shop equipped with
the necessary equipment. Do not
use makeshift equipment that may
damage the motorcycle.
