GENERAL INFORMATION
Because gasoline is used so often, many people forget
that it is hazardous. Only use gasoline as fuel for gasoline
internal combustion engines. Keep in mind, when work-
ing on a vehicle, gasoline is always present in the fuel
tank, fuel line and carburetor. To avoid a disastrous acci-
dent when working around the fuel system, carefully ob-
serve the following precautions:
1. Never use gasoline to clean parts. See Cleaning Parts
in this chapter.
2. When working on the fuel system, work outside or in a
well-ventilated area.
3. Do not add fuel to the fuel tank or service the fuel sys-
tem while the vehicle is near open flames, sparks or where
someone is smoking. Gasoline vapor is heavier than air. It
collects in low areas and is more easily ignited than liquid
gasoline.
4. Allow the engine to cool completely before working
on any fuel system component.
5. When draining the carburetor, catch the fuel in a plas-
tic container and then pour it into an approved gasoline
storage devise.
6. Do not store gasoline in glass containers. If the glass
breaks, a serious explosion or fire may occur.
7. Immediately wipe up spilled gasoline with rags. Store
the rags in a metal container with a lid until they can be
properly disposed of, or place them outside in a safe place
for the fuel to evaporate.
8. Do not pour water onto a gasoline fire. Water spreads
the fire and makes it more difficult to extinguish. Use a
class B. BC or ABC fire extinguisher to extinguish the
fire.
9. Always turn off the engine before refueling. Do not
spill fuel onto the engine or exhaust system. Do not over-
fill the fuel tank. Leave an air space at the top of the tank
to allow room for the fuel to expand due to temperature
fluctuations.
Cleaning Parts
Cleaning parts is one of the more tedious and difficult
service jobs performed in the home garage. There are
many types of chemical cleaners and solvents available
for shop use. Most are poisonous and extremely flamma-
ble. To prevent chemical exposure, vapor buildup, fire and
serious injury, observe each product warning label and
note the following:
1. Read and observe the entire product label before using
any chemical. Always know what type of chemical is be-
ing used and whether it is poisonous and/or flammable.
2. Do not use more than one type of cleaning solvent at a
time. If mixing chemicals is called for, measure the proper
amounts according to the manufacturer.
3. Work in a well-ventilated area.
4. Wear chemical-resistant gloves.
5. Wear safety glasses.
6. Wear vapor respirator if the instructions call for it.
a
7. Wash hands and arms thoroughly after cleaning parts.
8. Keep chemical products away from children and pets.
9. Thoroughly clean all oil, grease and cleaner residue
from any part that must be heated.
10. Use a nylon brush when cleaning parts. Metal brushes
may cause a spark.
11. When using a parts washer, only use the solvent rec-
ommended by the manufacturer. Make sure the parts
washer is equipped with a metal lid that will lower in case
of fire.
Warning Labels
Most manufacturers attach information and warning la-
bels to the vehicle. These labels contain instructions that
are important to personal safety when operating, servic-
ing, transporting and storing the vehicle. Refer to the
owner's manual for the description and location of labels.
Order replacement labels from the manufacturer if they
are missing or damaged.

SERIAL NUMBERS

Serial numbers are stamped onto the frame and engine.
Record these numbers in the Quick Reference Data sec-
tion at the front of the book. Have these numbers available
when ordering parts.
The frame number (Figure 1) or vehicle identification
number (VIN) is located on the side of the tunnel.
The engine number (Figure 2) is stamped into the right
end of the engine crankcase.
