NOTE: FIRE/ EXPLOSIONHAZARD

NOTE: Use propane

The propane canister contains enough gas to
cause serious fire, explosion, and burns. To reduce
chance of leak, fire, or explosion, take the following

only in containers

specifically

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

precautions:

should be familiar with the smell of propane
(smells like sulfur or rotten eggs). If at anytime the
smell of propane is identified, turn the engine off.

BE_O_ JSE

If the leak persists, remove the propane 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.

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 unit off.
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.
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.
1. Use only in well ventilated

areas. If you

experience headache, drowsiness, or nausea,
turn unit offand get fresh air quickly.

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

appliance

instructions.

2. Never use where people are sleeping.
3. Follow unit instructions for proper use.

Never use near pilot lights, flames, sparks, or other
ignition sources. They can ignite leaking gas.
1. Keep out of reach of children.
2. Never expose cylinder to heat, sparks, or flame.
Never leave in direct sunlight. Never store at

above 120 degrees F° (49 C).
3. Never store in living spaces.

2. Detach cylinder when not in use.
3. Detach outdoors away from pilot lights, flames,

For a new engine, change the oil after the first 10
hours of operation. Change the oil while the
engine is still warm but not hot. The oil will flow
freely and carry away more impurities.

1. Unplug spark plug boot to prevent accidental
starting.
2. Remove the oil fill plug / dipstick.
3. Pour the oil out of the oil fill hole and into a
container by tipping the unit to its side (Fig. 17).
Allow ample time for complete drainage.

Clean and re-oil the air filter every 10 hours of
operation. It is an important item to maintain.
Failure to maintain your air filter properly can result
in poor performance or can cause permanent
damage to your engine.

The condition of the air filter is important to the

NOTE:Checking the fuel, cleaning the air filter, and
adjusting the idle speed should solve most engine
problems. If not and all of the following are true:
•The engine will not idle.
•The engine hesitates or stalls on acceleration.
• There is a loss of engine power.
Check the spark plug for proper gap and condition.
If problem still occurs, have the carburetor
adjusted by an authorized service dealer.

8. Pull the starter rope slowly to bring the piston
to the top of its travel, (This position is known as
top dead center). Check that the piston is at the
top of its travel by looking down into the spark
plug hole. Both valves should be closed and the
rocker arms should move freely. If this statement
is not true, repeat this step.
9. Slide a feeler gage between the rocker arm and
the valve return spring. Measure the distance
between the rocker arm and valve stem (Fig. 24).
Take care to only measure the free play. It is very
easy to insert too thick a feeler gauge and
accidentally depress the valve and spring.
Measure both the intake and exhaust valve
clearances.

This requires partial disassembly of the engine.
If you feel unsure or unqualified
to perform this,
take the unit to an authorized
service center.
NOTE: Inspect the valve to rocker arm clearance
with a feeler gage after the first 25 hours of
operation. The engine must be cold when checking
or adjusting the valve clearances. This task should
be performed
in a clean dust free environment.
1. Remove the five screws on the engine cover
with a phillips head screw driver (Fig. 22).
