WARNING:
PROPANE IS HIGHLY FLAMMABLE, AND ITS
VAPORS CAN EXPLODE IF IGNITED.
SAFETY WARNINGS FOR PROPANE UNITS
CARBON MONOXIDE HAZARD
Burning propane makes Carbon Monoxide (CO). CO is
invisible, has no smell and can kill you. Operating your
outboard engine in an enclosed area can be dangerous.
1. Use only in well ventilated areas. If you experience
headache, drowsiness, or nausea, turn unit o and
get fresh air quickly.
2. Never use where people are sleeping.
3. Follow unit instructions for proper use.
HANDLING & STORAGE
1. Keep out of reach of children.
2. Never expose cylinder to heat, sparks, or ame.
Never store in direct sunlight.
Never store at temperatures above 120 degrees F°
(49°C).
3. Never store in living spaces.
4. Always use cylinder until it is completely empty.
5. Never rell a disposable cylinder. Relling may cause
an explosion. Federal law forbids transportation if
relled, a penalty up to $500,000, and 5 years
imprisonment (49 U.S.C. 5124).
6. Never store in luggage or take on trains or aircraft.
7. To discard, contact local refuse hauler or recycle center.
Never put in re or incinerator. Do not puncture.
If your cylinder was purchased with a “Green Key” * or
similar device, install it when empty and cylinder may
be recycled with other steel items.
NOTE: FIRE/EXPLOSION HAZARD
Contains enough gas to cause serious re, explosion,
and burns. To reduce chance of leak, re, or explosion,
take the following precautions:
BEFORE USE
1. Check cylinder and appliance seals. Never use with
damaged or missing seals. Discard cylinder if dirt or
rust particles are in valve area.
2. Turn engine o.
3. Attach cylinder outdoors away from pilot lights, ames,
sparks or other ignition sources. These sources can
ignite leaking gas.
4. Hand tighten only. Never use tools to tighten.
Over tightening can damage seals.
5. Check for leaks. Put soapy water on connections.
Look for bubbles. Listen for hiss of escaping gas. Feel
for extreme cold. Smell for rotten egg odor. Do not
use if leaking.
6. Read and follow operation instructions.
DURING USE
Never use near pilot lights, ames, sparks, or other
ignition sources. They can ignite leaking gas.
AFTER USE
1. Turn engine o and let cool.
2. Detach cylinder when not in use.
3. Detach outdoors away from pilot lights, ames, sparks,
or other ignition sources, they can ignite leaking gas.
4. Replace cap to keep valve clean.
IN CASE OF FIRE
1. Leave area quickly and call for help.
2. Let the cylinder burn out.
UNDERSTANDING PROPANE
NOTE: Use propane only in containers and/or remote
larger tanks specically designed and approved for this
unit. Propane is a combustible gas, it is colorless and
thus invisible to the naked eye. Propane has a harmless
odorant added so that it is possible to smell it. The user
should be familiar with the smell of propane (smells like
sulfur or rotten eggs). If at any time the smell of propane
is identied, turn o the engine. If the leak persists,
remove the pro-pane canister. Never attempt to operate
a unit that has a suspected leak. Always remove the
propane canister from any unit that has a suspected leak.
