UNDERSTANDING PROPANE
LEHR | ALL RIGHTS RESERVED 2009-2010 7
SAFETY WARNINGS FOR PROPANE UNITS
NOTE: Use propane only in containers specically
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 identied, turn the engine o.
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.
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.
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.

temperatures above 120 degrees F° (49 C).
3. Never store in living spaces.
4. Always use cylinder until it is completely empty.
5. Never rell a disposable cylinder. Relling may
cause an explosion. Federal law forbids
transportation if relled, 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 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.
* Green Key- is a trademark of the Coleman company

CARBURETOR ADJUSTMENT
The idle speed of the engine isadjustable. An idle
adjustment screw ison the rear side of the
carburetor (Fig. 20).
NOTE: Careless adjustments can seriously damage
your unit. An authorized service dealer should
make carburetor adjustments.
CLEAN AIR FILTER
The condition of the air lter is important to the
operation of the unit. A dirty or oil saturated air
lter will restrict air ow. This is often mistaken for
an out of adjustment carburetor. Check the
condition of the air lter before adjusting the idle
speed screw. Refer to Cleaning the Air Filter (p. 13).
ADJUST IDLE SPEED SCREW
If, after checking the fuel and cleaning the air lter,
the engine still will not idle, adjust the idle speed
screw as follows:
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
at 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 lter, 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.
REPLACING THE SPARK PLUGS
Use a replacement part number NGK CMR6A, or
Champion RCJ6Y. The correct air gap is 0.02 in.
(0.5 mm). Remove the plugafter 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 rmly 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 sparkplug. Set
the air gap at 0.02 in. (0.5 mm.) using a feeler
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.

MAINTENANCE
ROCKER ARM CLEARANCE ADJUSTMENT
This requires partial disassembly of the engine.
If you feel unsure or unqualied 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 rst 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 ve 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.
5. Clean dirt from around the rocker arm cover.
6. Remove the three screws holding the rocker
arm cover with a phillips head screwdriver.
7. Remove the rocker arm cover and gasket (Fig. 23).
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.
10. Check the spark plug and reinstall. Refer to
Replacing the Spark Plug (p.14).
11. Reinstall the spark plug wire.
IF THE CLEARANCE IS NOT WITHIN SPECIFICATION
1. Loosen the jam nut and turn the adjusting screw
as necessary. To increase the clearance, turn the
adjusting screw CCW. To decrease the clearance,
turn the adjusting screw CW.
2. Tighten the jam nut when the clearance is set.
3. Recheck the both clearances. Readjust if
necessary.
4. Reinstall the rocker arm cover using a new
gasket.
5. Tighten cover screws evenly until snug.
6. Reinstall the engine cover checking the
alignment of the cover. Tighten the ve engine
cover screws until snug.
• The recommended clearance for both intake and
exhaust is 0.003-0.006in (0.076-0.152mm).
• Use a standard automotive 0.005in (0.127mm) feeler
gage.

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 o-road engine. In California and
the 49 states, new equipment that use small o-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 o-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,
lters, 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 o-road engine at no cost to you including diagnosis, parts and
labor at an authorized service dealer.
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 o-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 o-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 o-road engine owner, you should be aware
that LEHR may deny you warranty coverage if your small o-road engine
or a part has failed due to abuse, neglect, or improper maintenance or
unapproved modications.
You are responsible for presenting your small o-road engine to a LEHR
service center as soon as the problem exists. The warranty repairs should
be completed 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
o-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 as to 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 dened 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 dened in Subsection (b). A statement in such written
instructions to the eect 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 rst scheduled replacement
point for that part. If the part fails prior to the rst 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 rst 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 dened
in Subsection (b), the manufacturer must maintain a supply of warranted
parts sufcient 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 modied parts that are not exempted by the Air Resources Board
may not be used. The use of any non-exempted add-on or modied 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 modied part. The manufacturer issuing the warranty
shall provide any documents that describe that manufacturer’s warranty
procedures or policies within ve 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 Mufer.
LEHR will furnish with each new engine written instructions for the
maintenance and use of the engine by the owner.
