Introduction and Safety

These safety alerts cannot eliminate the hazards that

they indicate. Common sense and strict compliance with

the special instructions while performing the action or

service are essential to preventing accidents.

The operator is responsible for proper and safe use of

the equipment. The manufacturer strongly recommends

that if the operator is also the owner, to read the owner’s

manual and thoroughly understand all instructions before

using this equipment. The manufacturer also strongly

recommends instructing other users to properly start and

operate the unit. This prepares them if they need to oper-

ate the equipment in an emergency.

How to Obtain Service

When the unit requires servicing or repairs, contact a

GMASD for assistance. Service technicians are factory-

trained and are capable of handling all service needs. Go

to www.generac.com/Service/DealerLocator/ for assis-

tance locating a dealer.

When contacting a GMASD about parts and service,

always supply the complete model and serial number of

the unit as given on its data decal located on the unit.

Record the model and serial numbers in the spaces

provided on the inside front cover of this manual.

General Hazards

•DO NOT run unit indoors or in an area with poor

ventilation. Verify engine exhaust cannot seep into

closed rooms or ventilation equipment.

•DO NOT clean air filter with gasoline or other types

of low flash point solvents.

•DO NOT clean internal or external components

humans. Engine oil can damage or contaminate

concrete, asphalt, and dirt.

•Shut down the engine if any of the following

conditions exist during operation:

– Noticeable change in engine speed.

(000419)

Personal injury. Wear appropriate personal protective

equipment at all times while operating and servicing

unit. Failure to do so could result in personal injury.

4Owner’s Manual for Flameless Air Heater

Introduction and Safety

•Before servicing the unit, verify the control power

switch is OFF (O), and the negative (-) terminal on

the battery is disconnected. DO NOT perform even

routine service (oil/filter changes, cleaning, etc.)

unless all electrical components are shut down.

•Replace all missing and hard to read decals.

Decals provide important operating instructions

and warn of dangers and hazards.

Trailer Hazards

Driving a vehicle with a trailer in tow is different than

driving the same vehicle without a trailer in tow. Consider

the following:

•It takes longer to get up to speed.

•More room is needed to turn and pass.

•More distance is needed to stop.

•The driver is responsible for keeping the vehicle

and trailer in control.

While towing, make regular stops to verify the following:

•Coupler is secured and locked to the hitch.

•Electrical connections are made.

•Appropriate slack in the safety chains.

•Appropriate slack in the breakaway switch pull-pin

cable.

•Tires are inflated to proper air pressure with no

damage or unusual wear to tread or sidewalls.

•Trailer doors are secured and latched.

Other towing guidelines:

•Use your mirrors to verify there is enough room for

lane changes or entering/exiting traffic.

•Allow plenty of stopping distance for the trailer and

tow vehicle.

•Do not drive faster than the conditions allow.

•A rule of thumb for passing distance is the distance

with a trailer is four times the passing distance

without a trailer.

•Use lower gears for climbing and descending

grades.

•Do not ride the brakes while descending grades;

this can cause overheating and potential brake fail-

ure.

•Do not apply the tow vehicle brakes to correct

extreme trailer swaying. Continued pulling of the

trailer, and even slight acceleration, or carefully

applying the trailer brakes (using the electronic

brake controller) will provide a stabilizing force.

Wheel Chock Guidelines

•DO NOT leave the unit coupled to the tow vehicle,

or use the breakaway brake system as a substitute

for wheel chocking.

•Select wheel chock according to equipment type

and size.

•Always use in pairs and on firm surfaces.

•Chock in direction of grade.

•Chock both sides of wheel if direction of grade is

unknown.

•Use wheel chock only after parking brake is

applied and tested.

•Center chocks squarely against tread of each

wheel.

•Do not drive over wheel chocks.

WARNING

Personal injury. Trailer must be securely coupled to

the hitch with the chains correctly attached. Uncoupled

or unchained towing could result in death or serious

injury. (000233a)

(000234a)

WARNING

Crushing hazard. Verify unit is properly secured and

on level ground. An unsecured unit can suddenly roll

or move, causing death or serious injury.

WARNING

Property or Equipment Damage. Tighten wheel lug

nuts after first 50 miles to factory specifications.

Failure to do so could result in death, serious injury,

property or equipment damage. (000235)

WARNING

Rollover hazard. Unit must be placed on flat, level

ground to prevent tipping or rollover. Failure to do so

could result in death, serious injury, or property or

equipment damage. (000283)

WARNING

Property or equipment damage. Do not alter the trailer.

Alterations can damage essential safety items. Doing

so could result in death, serious injury, or property or

equipment damage. (000285)

(000234a)

WARNING

Crushing hazard. Verify unit is properly secured and

on level ground. An unsecured unit can suddenly roll

or move, causing death or serious injury.

Owner’s Manual for Flameless Air Heater 5

Introduction and Safety

Towing Safety

Towing a trailer requires care. The trailer and vehicle

must be in good condition and securely fastened to each

other to reduce the possibility of an accident. Some

states require that large trailers be registered and

licensed. Contact your local Department of

Transportation office to verify license requirements for

your particular unit.

Hitch and Coupling

•Verify the hitch and coupling on the towing vehicle

are rated equal to, or greater than, the trailer's

Gross Vehicle Weight Rating (GVWR).

•Verify the trailer hitch and the coupling are compat-

ible. Make sure the coupling is securely fastened to

the vehicle.

•DO NOT tow the trailer using defective parts.

Inspect the hitch and coupling for wear or damage

before every tow.

•To eliminate squeaking, wipe the coupler clean and

apply fresh grease each time the trailer is towed.

•Connect safety chains in a crossing pattern under

the tongue.

•Before towing the trailer, verify that the weight of

the trailer is equal across all tires. On trailers with

adjustable height hitches, adjust the angle of the

trailer tongue to keep the trailer as level as possi-

ble.

Safe Towing Techniques

•Practice turning, stopping, and backing up in an

area away from heavy traffic prior to transporting

the unit.

•Maximum recommended speed for highway towing

is 45 mph (72 km/h). Recommended off-road tow-

ing speed is 10 mph (16 km/h) or less, depending

on terrain.

•When towing, maintain extra space between vehi-

cles and avoid soft shoulders, curbs, and sudden

lane changes.

•Reduce speed before curves, and maintain speed

throughout the curve.

•Reduce speed before going over bumps or holes.

Keep your foot off the accelerator while going over

bumps or holes.

Reporting Trailer Safety Defects

If you believe your trailer has a defect which could cause

a crash, injury or death, you should immediately inform

the National Highway Traffic Safety Administration

(NHTSA) in addition to notifying Generac Mobile.

If NHTSA receives similar complaints, it may open an

investigation. If it finds that a safety defect exists in a

group of vehicles, it may order a recall and remedy cam-

paign. However, NHTSA cannot become involved in an

individual problem between you, your dealer, or Generac

Mobile.

To contact NHTSA, you may either call the Auto Safety

Hotline toll-free at 1-888-327-4236 (TTY:1-800-424-

9153), go to http://www.safercar.gov; or write to:
