SAFETY

1

Handle Fuel Safely

Handle fuel with care—it is highly flammable.

!

WARNING

Store fuel according to local, state, or federal ordinances 
and recommendations from your fuel supplier.

Never overfill or allow the tank to become empty. 

Use clean, fresh fuel.

Do not fill above the fuel filler neck.

Store Volatile and Hazardous 
Materials Safely

Store volatile materials (gasoline, diesel fuel, oil, etc.) in 
approved containers that are clearly marked. Containers 
should be stored in an approved safety cabinet away 
from possible sources of ignition. Storage areas and 
cabinets should be well ventilated to prevent the possible 
build-up of fumes. 

Handle Chemical Products 
Safely 

!

WARNING

Routine service often requires the use of various 
chemical products, including lubricants and cleaning 
solutions. Many of these chemicals are flammable and 
can pose health risks if not handled properly. 

• Never mix chemicals. Mixing chemicals can produce 

toxic or explosive results.

• Follow the manufacture’s recommendations for safe 

usage and handling of the product.

• Various materials may pose a health hazard if used 

incorrectly. A Material Safety Data Sheet (MSDS) 
contains important information regarding proper 
handling and health hazards, as well as emergency 
response procedures. Contact the chemical 
manufacturer to obtain an MSDS for the chemical 
product. 

Service Electrical Components 
Safely

!

WARNING

• Disconnect the battery negative (–) cable before 

removing or installing electrical components. Always 
connect the battery negative (–) cable last. 

• Certain test and adjustment procedures must be 

performed with the battery connected. Use care to 
prevent arcing when working on live circuits or 
components. Arcing can cause component damage 
and could ignite flammable materials. 

• Never remove the fuel cap from the fuel tank, 

or add fuel, when the engine is running or 
while the engine is hot.

• Do not smoke when handling fuel. Never fill 

or drain the fuel tank indoors.

• Do not spill fuel. Clean spilled fuel 

immediately.

• Never handle or store fuel containers near an 

open flame or any device that may create 
sparks and ignite the fuel or fuel vapors.

• Be sure to reinstall and tighten fuel cap 

securely.

• Use an approved container; the spout must fit 

inside the fuel filler neck. Avoid using cans 
and funnels to transfer fuel.

Exposure to chemical products could result in 
serious injury. Handle chemical products with 
care. Refer to the chemical manufacturer’s 
Material Safety Data Sheet (MSDS) for information 
regarding health hazards, safe handling, and 
emergency response procedures.

Always disconnect the negative terminal first and  
positive terminal last. Connect positive terminal 
first and negative terminal last. Use care when 
testing live circuits to prevent arcing. Arcing 
could result in death or serious injury.

Dispose of Waste Materials 
Safely

Routine service can produce waste products such as 
used oil, grease, and used batteries. 

If not handled properly, these materials can pose a threat 
to the environment. 

Collect fluids in well-marked, approved storage 
containers. Some waste fluids can react with certain 
types of plastics. Make sure the fluid to be stored is 
compatible with the storage container. Never use food or 
beverage containers to store waste fluids. 

IMPORTANT

• Dispose of waste fluids properly at approved local 

recycling centers. If recycling facilities are not 
available, contact your local community for the 
correct disposal procedure for waste fluids. 

• Dispose of old batteries properly. Battery electrolyte 

contains sulfuric acid and other hazardous materials. 
Never place an old battery in the trash. Batteries 
must be disposed of in a manner consistent with EPA 
and/or local regulations. 

Never dispose of waste fluids by pouring on the 
ground, down sewer drains, or into any body of 
water.
