2.3 Inspection Tips
1. Bolts and bolt heads use the International Standard (Metric) measurement system.
Use of tools other than those complying with the Metric system may cause
damage to the parts.
2. Clean parts of any outside dirt or deposits before maintenance to prevent the
chance of contaminants dropping into the engine and causing damage.
3. Use kerosene to clean-up disassembled parts. Check and measure parts after
clean-up. Apply engine oil for lubrication to any contact and sliding surfaces of
parts.
4. The packing, metal gasket, O-ring, seal, clamp, and clipper should be replaced
with new ones after disassembly.
5. Pay attention to the orientation and relative positions of the major components.
Arrange the parts in order during disassembly. Make marks if necessary to avoid
mistakes in re-assembly.
6. Removing parts should start from small to big, from outside to inside. Assembly
is in reverse order of disassembly.
7. The oil seals should be replaced with new ones after disassembly. The contact
surface should be cleaned-up. Check shafts for scratches or burrs. Use special
tools for assembly to avoid damaging the seal lip area. The manufacturer logo
should face outward on seals and bearings. Apply grease at seal lip area.
8. Disconnect the battery negative (-) terminal before maintenance. Connect the
positive (+) terminal first in assembly. Apply a thin layer of grease on terminals,
and cover with terminal caps.
2.4 Safety Precautions
Warning: Engine Exhaust
Keep the area well ventilated during engine operation. Do not operate engine in an
enclosed area. Carbon monoxide (CO) in exhaust fumes may lead to loss of
consciousness and even death.
Warning: Petrol
Petrol is highly flammable. Avoid any naked flame during inspection of the petrol tank or
of a petrol leak.
Warning: Battery Gasses and Battery Liquid

1. The battery liquid is highly corrosive. Avoid contact of the liquid with skin or eye.
If any contact occurs, wash with large quantities of clean water and in the case of
eye contact, consult a doctor.
2. The hydrogen released from battery during charging is explosive. Keep the area
well ventilated during battery charging and avoid naked flame.
Warning: Brake Fluid
Brake fluid can damage the paint and some plastics. Cover the parts that can be damaged
with cloth during maintenance of hydraulic brakes. If the brake fluid is spilt on plastic or
a painted component, remove the fluid and wash the surface with water immediately.
Warning: High Temperature of Engine
The engine cover, cylinder, and exhaust pipe can be at a high temperature after the engine
has been running. Wait for the engine to cool before working on it or use protective
gloves.
