SAFETY WARNINGS
FOR PROPANE UNITS
NOTE: FIRE/EXPLOSION
HAZARD
NOTE: Use propane only in containers specifically
designed and approved for this unit. Propane is a

and burns. To reduce chance of leak, fire, or explosion:
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 propane odorant
makes the propane smell like sulfer or rotten eggs.
BEFORE USE
If at any time the smell of propane is identified,
turn offthe 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.
CARBON MONOXIDE
HAZARD
Burning propane makes Carbon Monoxide (CO). CO is
invisible, has no smell and can kill you. Operating your
trimmer in an enclosed area can be dangerous.
I. Use only in well ventilated areas. If you experience
headache, drowsiness, or nausea, turn unit offand
get fresh air quickly.
2. Never use where people are sleeping.
3. Follow unit instructions for proper use.
1. Check propane cylinder and trimmer
3. Attach cylinder outdoors away from pilot lights, flames,
sparks or other ignition sources. These sources can
ignite leaking gas.
4. Hand tighten only. Never use tools to tighten. Overtightening 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 trimmer
instructions.

& STORAGE
1. Keep out of reach of children.
2. Never expose cylinder to heat, sparks, or flame.
Never leave in direct sunlight. Never store at tern peratures above 120 degrees (49 degrees C).
3. Never store in living spaces.
4. Always use cylinder until it is completely empty.
5. Never refill a disposable cylinder. Refilling may cause
an explosion. Federal law forbids transportation
if re filled, imposes a penalty up to $500,000, and 5 years
imprisonment
(49 U.S.C.5124).
6. Never put in luggage or take on trains or aircraft.
7. To discard, contact local refuse hauler or recycle center.
Never put in fire 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.

Do not force the cutting attachment. Allow the tip
of the line to do the cutting, especially along walls.
Cutting with more than the tip will reduce cutting
efficiency and may overload the engine.
• Cut grass over 8 inches (200 mm) by cutting from top
to bottom in small increments to avoid premature line
wear or engine drag.
Slowly move the trimmer into and out of the cutting
area at the desired height. Move either in a forwardbackward or side-to-side motion. Cutting shorter
lengths produces the best results.

NOTE: Careless adjustments can seriously damage
your unit. Only a Sears or other qualified dealer should
make carburetor
adjustments.
CLEAN AIR FILTER
The condition of the air filter is important to the operation of the unit. A dirty or oil saturated air filter will
restrict air flow. This is often mistaken for an out of
adjustment carburetor. Check the condition of the air
filter before adjusting the idle speed screw. Refer to
Cleaning Air Filter (p.13).
