iF yOu SMeLL GaS

1. nO FLaMeS Or SparKS!

Immediately put out all smoking

materials and other open flames.

Do not operate lights, appliances,

telephones, or cell phones.

Flames or sparks from these sources

can trigger an explosion or a fire.

2. LeaVe THe area iMMeDiaTeLy!

Get everyone out of the area where

you suspect gas is leaking.

3. SHuT OFF THe GaS. Turn off the

main gas supply valve on your

propane tank, if it is safe to do

so. To close the valve, turn it to

the right (clockwise).

4. repOrT THe LeaK. From a

neighbor’s home or other nearby

building away from the gas leak, call

your propane retailer right away. If

you can’t reach your propane retailer

call 911 or your local fire department.

5. DO nOT reTurn TO THe area

until your propane retailer,

emergency responder, or qualified

service technician determines

that it is safe to do so.

6. GeT yOur SySTeM CHeCKeD.

Before you attempt to use your

generator your propane retailer

or a qualified service technician

must check your entire system

to ensure that it is leak-free.

Can yOu SMeLL iT?

Propane smells like rotten eggs, a

skunk’s spray, or a dead animal. Some

people may have difficulty smelling

propane due to their age (older people

may have a less sensitive sense of

smell); a medical condition; or the effects

of medication, alcohol, tobacco, or drugs.

ODOr LOSS. On rare occasions,

propane can lose its odor. Several

things can cause this including:

•

The presence of air, water, or rust

in a propane tank or cylinder.

•

The passage of leaking

propane through the soil.

Since there is a possibility of

odor loss or problems with your

sense of smell, you should

respond immediately to even

a faint odor of propane.

GaS DeTeCTOrS

Under some circumstances, you may

not smell a propane. Propane detectors

(not included) sound an alarm if they

sense propane in the air. They can

provide an additional measure of security.

You should consider the purchase of

one or more detectors for your home.

GuiDeLineS regarding

propane detectors:

•

Buy only units that are listed

under the latest Underwriters

Laboratories (UL) standard.

•

Follow the manufacturer’s

instructions regarding installation

and maintenance.

•

Never ignore the smell of

propane, even if no detector

is sounding an alarm.

GeneraTOr MainTenanCe

LeaVe iT TO THe eXperTS.

Only a qualified service technician

has the training to install, inspect,

service, maintain, and repair your

generator. Have your generator and

propane system inspected annually.

DO nOT Try TO MODiFy Or repair

valves, regulators, connectors, controls,

or other generator and cylinder/tank parts.

Doing so creates the risk of a gas leak

that can result in property damage,

serious injury, or death.

CO anD yOur SaFeTy

WHaT iS CarBOn MOnOXiDe (CO)?

You can’t taste or smell CO, but it is

a very dangerous gas. High levels of

CO can come from engine exhaust

fumes, appliances that are not operating

correctly, or from a venting system

or chimney that becomes blocked.

CO Can Be DeaDLy! High levels of CO

can make you dizzy or sick. In extreme

cases, CO can cause brain damage

or death. Symptoms of CO poisoning

include: headache, dizziness, fatigue,

shortness of breath, and nausea.

iF yOu SuSpeCT CO iS

preSenT, aCT iMMeDiaTeLy!

1. If you or a family member shows

physical symptoms of CO poisoning,

get everyone out of the area and call

911 or your local fire department.

2. If it is safe to do so, turn off

any appliances you suspect

may be releasing CO.

3. If no one has symptoms, but you

suspect that CO is present, call

your propane retailer, or a qualified

service technician to check CO

levels and your propane.

CO DeTeCTOrS Can iMprOVe

SaFeTy. For an extra measure

of safety, consider installing a CO

detector (not included) listed by

UL on each level of your home.

TO HeLp reDuCe THe riSK

OF CO pOiSOninG:

•

Have a qualified service technician

check your propane appliances and

venting systems annually, preferably

before the heating season.

•

LpG/propane precautions

1. LPG / Propane system must be installed and

used in strict conformance with NFPA 58

(Liquefied Petroleum Gas Code), NFPA 54

(National Fuel Gas Code), manufacturer’s

recommendations, and all relevant local,

state, and federal codes and regulations.

2. LPG / Propane and Gasoline fuel and fumes are

flammable, and potentially explosive. Use proper

fuel storage and handling procedures. Do not

store fuel or other flammable materials nearby.

3. Fire and explosion hazard. Never use a

gas container, LPG/propane connector

hose, LPG/propane tank, or any other fuel

item that appears to be damaged.

4. Fire and explosion hazard. Only use approved

LPG/propane tanks with an Overfilling Prevention

Device (OPD) valve. Keep the tank in a vertical

position with the valve on top and placed at

ground level on a flat surface. Do not allow tanks

to be near any heat source. When transporting

and storing, turn the propane tank valve to the

fully closed position and disconnect the tank.

Make sure to always cover the generator inlet

and tank outlet with protective plastic caps.

5. Connect LPG/propane tank using provided

attachment kit only. Kit includes 1.5 meter

(4.9 ft) hose. Place tank as far away from

Generator as hose allows and away from engine

exhaust. Do not place tank above Generator.

6. Fire and explosion hazard. If there is a strong

smell of Propane while operating the generator,

fully close the LPG / Propane tank valve and shut

down the Generator immediately. Once the LPG

is off, use soapy water to check for leaks on the

hose and connections on the tank valve and the

generator. Do not smoke or light a cigarette or

check for leaks using any open flame source

such as a match or lighter. If a leak is found,

contact a qualified technician to inspect and repair

the LPG system before using the generator.

7. Generator will produce carbon monoxide

when burning gasoline or LPG.

8. When exchanging LPG/propane tanks, be sure

the tank connector is the same size and thread.

9. LPG/Propane will freeze skin. Prevent leaking

propane from contacting skin at all times.

10. LPG / Propane is highly flammable and explosive.

11. LPG/Propane is heavier than air and

will accumulate in low places.

12. LPG / Propane has a distinctive odor added

to help detect potential leaks. This odor can

diminish over time or due to other factors.

13. Keep LPG / Propane tanks in an upright position.

14. In case of a LPG / Propane fire, do not attempt

to extinguish unless the fuel supply can be

shut off safely. Leave the area immediately

and call 911 or your local fire department.

15. Keep the LPG / Propane tank and hose

away from engine exhaust.

16. Do not insert any object other than the

matching plug into the quick-disconnect

coupling. This may cause the coupling to

leak, disconnect, or otherwise fail.

17. Do not allow the hose to be kinked, pinched,

twisted, or torqued during installation.

18. Protect hose and fittings from dust

and dirt while disconnected.

for your failure to ensure the performance of all scheduled maintenance.

As the Small Off-Road Engine and engine powered equipment owner, you should however be aware that HFT may

deny you warranty coverage if your Small Off-Road Engine or engine powered equipment or a part has failed due to

abuse, neglect, improper maintenance, or unapproved modifications.

You are responsible for presenting your Small Off-Road Engine or engine powered equipment to HFT as soon as

the problem exists. To obtain warranty repair or replacement, either:

a) The warranty period begins on the date the engine or equipment is delivered to an ultimate purchaser. The

warranty period is two years.

b) HFT warrants to the ultimate purchaser and each subsequent owner that the engine is:

1. Designed, built, and equipped so as to conform with the applicable United States Environmental Protection

Agency’s (EPA) emissions requirements in effect at the time of manufacture and all applicable regulations

adopted by the California Air Resources Board; and

2. Free from defects in materials and workmanship that cause the failure of a warranted part to be identical in

all material respects to the part as described in the engine manufacturer’s application for certification for a

period of two years.

c) The warranty on emissions-related parts is as follows:

1. Any warranted part that is not scheduled for replacement as required maintenance in the written instructions

provided is warranted for the warranty period stated above. If any such part fails during the period of warranty

coverage, it will be repaired or replaced by HFT. Any such part repaired or replaced under the warranty will

be warranted for the remaining warranty period.

2. Any warranted part that is scheduled only for regular inspection in the written instructions is warranted for

the warranty period stated above. A statement in the written instructions to the effect of “repair or replace

as necessary” does not reduce the period of warranty coverage. Any such part repaired or replaced under

warranty will be warranted for the remaining warranty period.

3. Any warranted part that is scheduled for replacement as required maintenance in the written instructions will

be warranted for the period of time prior to the first scheduled replacement point for that part. If the part fails

prior to the first scheduled replacement, the part will be repaired or replaced by HFT. Any such part repaired

or replaced under warranty will be warranted for the remainder of the period prior to the first scheduled

replacement point for the part.

4. Repair or replacement of any warranted part under the warranty will be performed at no charge to the owner

at a retail store or by HFT paying for shipping the product for repair.

5. Notwithstanding the provisions herein, warranty services or repairs will be provided at all retail stores or by

contacting HFT Product Support at 1-800-444-3353 or [email protected].

6. The owner will not be charged for diagnostic labor that leads to the determination that a warranted part is in

fact defective, provided that such diagnostic work is performed at a retail store.

7. HFT is liable for damages to other engine components proximately caused by a failure under warranty of any

warranted part.

8. Throughout the engine’s and emission control system’s warranty period stated above, HFT will maintain a

supply of warranted parts sufficient to meet the expected demand for such parts and will obtain additional

parts if that supply is exhausted.

9. Any replacement part may be used in the performance of any warranty maintenance or repairs and will

be provided without charge to the owner. Manufacturer-approved replacement parts that do not increase

emissions will be used in the performance of any warranty maintenance or repairs and will be provided

without charge to the owner. Such use will not reduce the warranty obligations of HFT.

10. Add-on or modified parts that are not exempted by the California Air Resources Board may not be used. The

use of any non-exempted add-on or modified parts will be grounds for disallowing a warranty claim. HFT is

not liable to warrant failures of warranted parts caused by the use of a non-exempted add-on or modified

part.

11. HFT will provide any documents that describe its warranty procedures or policies upon request of the

Executive Officer.
