Handling Gasoline Safely
Gasoline is a volatile flammable liquid and is one of the most dangerous items in the shop.
Because gasoline is used so often, many people forget it is hazardous. Only use gasoline as fuel
for gasoline internal combustion engines. Keep in mind when working on the machine, gasoline is
always present in the fuel tank, fuel line and throttle. To avoid a disastrous accident when working
around the fuel system, carefully observe the following precautions:
1.
Never use gasoline to clean parts. Refer to Cleaning Parts in this section.
2.
When working of the fuel system, work outside or in a well-ventilated area.
3.
Do not add fuel to the fuel tank or service the fuel system while the UTV 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.
Do not store gasoline in glass containers. If the glass breaks, a serious explosion of fire may
occur.
6.
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.
7.
Do not pour water onto a gasoline fire. Water spreads the fire and makes it more difficult to put out.
Use a class B, BC or ABC fire extinguisher which are dedicated to extinguish the gasoline fire.
8.
Always turn off the engine before refueling. Do not spill fuel onto the engine or exhaust system.
Do not overfill 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.
Many types of chemical cleaners and solvents are available for shop use. Most are poisonous and
extremely flammable. 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 being 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 required,
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 a vapor respirator if the instructions call for it.
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 recommended by the manufacturer. Make sure
the parts washer is equipped with a metal lid that will lower in case of fire.
