_Ai::::_TYWArNiNGS U::::O_P_OPAN_ JNiT$ NOTE:FIRE/EXPLOSIONHAZARD
NOTE: Use propane 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
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.
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.
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.
2. Never use where people are sleeping.
3. Follow unit instructions for proper use.
The propane canister contains enough gas to
cause serious fire, explosion, and burns. To reduce
chance of leak, fire, or explosion, take the following
precautions:
BE_O_ JSE
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.
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.
DUi_iNG d_E
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
temperatures above 120 degrees F° (49 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 refilled, 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.

A::::/:::!$:
1.Turn unit offand let cool.
2. Detach cylinder when not in use.
3. Detach outdoors away from pilot lights, flames,
sparks, or other ignition sources, they can ignite
leaking gas.
4. Replace cap to keep valve clean.

Always use propane canisters or "bottles" that are
the correct size. The 17 ounce or 16.4 ounce /465g
canisters that are approximately 3-7/8 inches A
(9.5 cm) in diameter are the correct canisters //
(Fig. 4). Do not use smaller diameter canisters as
they will not latch securely to the unit and vibration
may cause damage to the unit and potentially
result in a dangerous leak.

The idle speed of the engine is adjustable. An idle
adjustment screw is on the rear side of the
carburetor (Fig. 20).
NOTE: Careless adjustments can seriously damage
your unit. An authorized service dealer should
make carburetor adjustments.
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 the Air Filter (p. 13).
If, after checking the fuel and cleaning the air filter,
the engine still will not idle, adjust the idle speed
screw as follows:
Use a replacement part number NGK CMR6A, or
Champion RCJ6Y. The correct air gap is 0.02 in.
(0.5 mm). Remove the plug after every 25 hours of
operation and check its condition.
1. Stop the engine and allow it to cool. Remove the
spark plug cover. Grasp the plug wire firmly and
pull the cap from the spark plug.
2. Clean dirt from around the spark plug. Remove
the spark plug from the cylinder head by using
a 5/8 in. socket turning it counterclockwise.
3. Replace cracked, fouled or dirty spark plug. Set
the air gap at 0.02 in. (0.5 mm.) using afeeler
gauge (Fig. 21).
4. Install a correctly-gapped spark plug in the
cylinder head. Turn the 5/8 in. socket clockwise
until snug.
NOTE: If using a torque wrench torque to:
110-120 in. lb. (12.3-13.5 N-m). Do not over
tighten.
k.
1. Start the engine and let it run at a high idle for a
minute to warm up. Refer to Starting /Stopping
(p. 10).
2. Release the throttle trigger and let the engine
idle. If the engine stops, use a small phillips or
fiat blade to turn the idle speed screw in,
clockwise, 1/8 of a turn at a time (as needed)
until the engine idles smoothly(Fig. 20).
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.

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).
2. Remove the engine cover.
3. Disconnect the spark plug wire.
4. Clean dirt from around the spark plug. Remove
the spark plug by using a 16mm socket, turn CCW.
Enc
8. Pull the starter rope slowly to bring the piston
to the top of its travel, (This position isknown 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.

YOUR WARRANTY RIGHTS AND OBLIGATIONS
The California Air Resources Board, the Environmental Protection Agency
and LEHR, Inc. are pleased to explain the emissions control system's
warranty on your 2009 and later small off-road engine. In California and
the 49 states, new equipment that use small off-road engines must be
designed, built, and equipped to meet the State's stringent anti-smog
standards. LEHR, Inc. must warrant the emissions control system on your
small off-road engine for the period listed below provided there has been
no abuse, neglect or improper maintenance of your equipment. Your
emissions control system may include parts such as: carburetors or fuel
injection system, ignition system, catalytic converters, fuel tanks, valves,
filters, clamps, connectors, and other associated components. Also,
included may be hoses, belts, connectors, sensors, and other emission-
related assemblies. Where a warrantable condition exists, LEHR will repair
your small off-road engine at no cost to you including diagnosis, parts and
labor at an authorized service dealen
MANUFACTURER'S WARRANTY COVERAGE:
This emissions control system is warranted for two years. If any emissions-
related part on your equipment is defective, the part will be repaired or
replaced by LEHR.
OWNER'S WARRANTY RESPONSIBILITIES:
As the small off-road engine owner, you are responsible for performance
of the required maintenance listed in your owner's manual. LEHR
recommends that you retain all receipts covering maintenance on your
small off-road engine, but LEHR cannot deny warranty solely for the lack of
receipts or your failure to ensure the performance of all scheduled
maintenance. As the small off-road engine owner, you should be aware
that LEHR may deny you warranty coverage if your small off-road engine
or a part has failed due to abuse, neglect, or improper maintenance or
unapproved modifications.
You are responsible for presenting your small off-road engine to a LEHR
service center as soon as the problem exists. The warranty repairs should
be corn pleted in a reasonable amount of time, not to exceed 30 days. If
you have a question regarding your warranty coverage, you should contact
LEHR at 1-866-941-LEHR.
DEFECTS WARRANTY REQUIREMENTS:
(a) The warranty period begins on the date the engine or equipment is
delivered to an ultimate purchaser.
(b) General Emissions Warranty Coverage. The manufacturer of each small
off-road engine or equipment must warrant to the ultimate purchaser
and each subsequent owner that the engine or equipment is:
Designed, built, and equipped so asto conform with all applicable
regulations adopted by the Air Resources Board; and free from defects in
materials and workmanship that causes the failure of a warranted part for
a period of two years.
(c) The warranty on emissions-related parts will be interpreted as follows:
Any warranted part that is not scheduled for replacement as required
maintenance in the written instructions required by Subsection (d) Must
be warranted for the warranty period defined in Subsection (b). If any
such part fails during the period of warranty coverage, it must be repaired
or replaced by the manufacturer according to Subsection (1) below. Any
such part repaired or replaced under the warranty must be warranted for
the remaining warranty period.
Any warranted part that is scheduled only for regular inspection in the
written instructions required by Subsection (d) must be warranted for the
warranty period defined in Subsection (b). A statement in such written
instructions to the effect of "repair or replace as necessary" will not reduce
the period of warranty coverage. Any such part repaired or replaced under
warranty must be warranted for the remaining warranty period.
Any warranted part that is scheduled for replacement as required
maintenance in the written instructions required by Subsection (d) must 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 must be repaired or replaced by the engine manufacturer
according to Subsection (1) below.
Section 1: Any such part repaired or replaced under warranty must be
warranted for the remainder of the period prior to the first scheduled
replacement point for the part. Repair or replacement of any warranted
part under the warranty must be performed at no charge to the owner at
a warranty station.
Notwithstanding the provisions of Subsection (1) above, warranty services
or repairs must be provided at all manufacturer distribution centers that
are franchised to service the subject engines. The owner must 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 warranty station. The manufacturer is liable for damages to
other engine components proximately caused by a failure under warranty
of any warranted part. Throughout the emissions warranty period defined
in Subsection (b), the manufacturer must maintain a supply of warranted
parts sufficient to meet the expected demand for such parts.
Any replacement part may be used in the performance of any warranty
maintenance or repairs and must be provided without charge to the owner.
Such use will not reduce the warranty obligations of the manufacturer.
Add-on or modified parts that are not exempted by the 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. The manufacturer will not
be liable to warrant failures of warranted parts caused by the use of a non-
exempted add-on or modified part. The manufacturer issuing the warranty
shall provide any documents that describe that manufacturer's warranty
procedures or policies within five working days of request by the Air
Resources Board.
(d) Emission Warranty Parts List.
The following components are included in the emission related warranty
of the engine:
Air Filter, Carburetor, Regulator, Fuel Lines & Fittings, Fuel Valve, Ignition Coil,
Spark Plug, Valves, CAM and Muffler.
LEHR will furnish with each new engine written instructions for the
maintenance and use of the engine by the owner.
