SAFTEY PRECAUTIONS 

 

A generator set can be potentially dangerous if not properly maintained and operated. The best Safe 

Guard against a dangerous situation is education, good judgment and common sense. For safe trouble free 
operation of your generator set some general precautions are listed below. Be sure to read, understand and 
follow these precautions. Please call Power Technology Southeast, Inc. with any concerns you may have with 
your generator set.  
 
1) 

HOT PIPING: 

An engine and exhaust system may get extremely hot while running. Do not work on a 

generator set until it has sufficiently cooled.   

 
2) 

DANGEROUS FUELS: 

Use extreme caution when handling, storing and using fuels. All fuels are highly 

explosive in a vaporous state. Store fuel in a well ventilated area away from spark producing 
equipment. Keep fuels and all chemicals out of the reach of children. Never add fuel to the 
tank while the engine is running. Spilled fuel may ignite on contact with hot parts or from 
ignition spark. Always keep fuel lines and connections tight and in good condition. Don’t 
replace flexible fuel lines with rigid lines. If you notice any fuel leakage, fuel accumulation 
or electrical sparks, DO NOT OPERATE THE GENERATOR SET. 

 
3) 

EXPLOSIVE BATTERY GASES: 

The gases generated by a battery being charged are highly explosive. 

Do not smoke or permit any flames or sparks to occur near a battery at any time, especially 
when it is being charged. Avoid contact between terminals with tools to prevent sparks and 
possible burns. Always remove wristwatch, rings, or other jewelry before handling a battery. 
Any compartment containing batteries should be well ventilated to prevent the accumulation 
of explosive gases. To avoid sparks never disturb the battery charging connections while the 
battery is being charged. Always turn off the battery charger before disconnecting terminal 
clips.  

 
4) 

ELECTROCUTION: 

Failure to install a generator set with an electrical system consistent with governing 

regulations and standards is UNLAWFUL and may cause ELECTROCUTION of vehicle 
occupants. Your generator set must not be used to “Back Feed” by connecting it to a building 
or outdoor electrical circuit. Back feeding can cause serious injury or death to utility 
personnel working to repair a power outage and may also seriously injure persons in your 
vehicle. Unauthorized connections are unlawful in some states and/or localities. A transfer 
switch must be installed to prevent interconnection of the generator set power and outside 
power. 

 
5) 

MOVING PARTS: 

Keep hands, feet, and clothing away from belts and related pulleys when unit is running. 

Replace guards, covers, and screens before operating the generator set. Serious personal 
injury may occur from contact with moving parts. 

 
6) 

HIGH VOLTAGE: 

Remember the function of a generator set is to produce electricity. Wherever electricity 

is present there is a potential danger of electrocution. Apply the same precautions to the 
vehicles electrical appliances as you would for any home appliance. Keep away from 
electrical circuits and wiring while the generator set is running. Have electrical service 
performed only by qualified electricians. Be sure any unauthorized person; especially 
children are denied access to the generator set. Keep the compartment door securely latched 
or locked at all times. Be sure the generator is properly grounded. Never touch electrical 
leads or appliances with wet hands, or when standing on wet ground.
