MAINTENANCE AND ADJUSTMENT OF THE EV

Amperage
Amperage is the unit of measurement for the amount of current within a circuit.
Current is the actual flow of electricity. The higher the current, the more work can be
performed up to a given point. If the current flow exceeds the circuit or component
capacity, it will damage the system.
Warning
If the current insulation damage, may cause short circuit fault which lead to short
circuit or large current in components. It may cause a fire.
Thus, if the current of circuit or components measured by amperage exceeds the
standard level, must check and repair electrical system at once.
BASIC SERVICE METHODS
Most of the procedures in this manual are straightforward 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 EV, The front of any component is the
end closest to the front the EV. 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 EV 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.
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. Perform the procedure in
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
