GENERAL SAFETY RULES

WARNING:

Read and understand all instructions. Failure to follow all
instructions listed below may result in electric shock, fire
and/or serious personal injury.

READ ALL INSTRUCTIONS

 For safe operation, read and understand all instructions

before using this product. Follow all safety instructions.
Failure to follow all safety instructions listed below, can
result in serious personal injury.

 Do not allow children or untrained individuals to use this

unit.

 Never start or run the engine in a closed or poorly venti-

lated area; breathing exhaust fumes can kill.

 Clear the work area before each use. Remove all objects

such as rocks, broken glass, nails, wire, or loose string
which can be thrown or become entangled in the cutting
line or blade.

 Always wear eye protection with side shields marked to

comply with ANSI Z87.1 along with hearing protection
when operating this equipment.

 Wear heavy, long pants, long sleeves, boots, and gloves.

Do not wear loose fitting clothing, short pants, sandals,
or go barefoot. Do not wear jewelry of any kind.

 Heavy protective clothing may increase operator fatigue,

which could lead to heat stroke. During weather that is
hot and humid, heavy work should be scheduled for early
morning or late afternoon hours when temperatures are
cooler.

 Product users on United States Forest Service land, and in

some states, must comply with fire prevention regulations.
This product is equipped with a spark arrestor; however,
other user requirements may apply. Check with your

federal, state, or local authorities.
 Never operate this unit on the operator’s left side.
 Secure long hair above shoulder level to prevent

entanglement in moving parts.
 Keep all bystanders, children, and pets at least

50 ft. away. Bystanders should be encouraged to wear

eye protection. If you are approached, stop the engine

and cutting attachment. In the case of bladed units, there

is the added risk of injury to bystanders from being struck

with the moving blade in the event of a blade thrust or

other unexpected reaction of the saw.
 Do not operate this unit when you are tired, ill, or under

the influence of alcohol, drugs, or medication.

 Do not operate in poor lighting.
 Keep firm footing and balance. Do not overreach.

Overreaching can result in loss of balance or exposure

to hot surfaces.

3 — English

 Keep all parts of your body away from any moving part.
 To avoid hot surfaces, never operate the unit with the

bottom of the engine above waist level.

 Do not touch area around the muffler or cylinder of the

unit, these parts get hot from operation. Contact with
hot surfaces could result in possible serious personal
injury.

 Always stop the engine and remove the spark plug wire

before making any adjustments or repairs except for
carburetor adjustments.

 Inspect the unit before each use for loose fasteners, fuel

leaks, etc. Replace any damaged parts before use.

 The cutting attachment should never rotate at idle during

normal use. The cutting attachment may rotate at idle
during carburetor adjustments.

 It has been reported that vibrations from hand-held tools

may contribute to a condition called Raynaud’s Syndrome
in certain individuals. Symptoms may include tingling,
numbness, and blanching of the fingers, usually apparent
upon exposure to cold. Hereditary factors, exposure to
cold and dampness, diet, smoking, and work practices
are all thought to contribute to the development of these
symptoms. It is presently unknown what, if any, vibrations
or extent of exposure may contribute to the condition.
There are measures that can be taken by the operator to
possibly reduce the effects of vibration:

a) Keep your body warm in cold weather. When operating

the unit wear gloves to keep hands and wrists warm.
It is reported that cold weather is a major factor con­tributing to Raynaud’s Syndrome.

b) After each period of operation, exercise to increase

blood circulation.

c) Take frequent work breaks. Limit the amount of

exposure per day.

d) Keep the tool well maintained, fasteners tightened,

and worn parts replaced.

If you experience any of the symptoms of this condition,

immediately discontinue use and see your physician about

these symptoms.
 Mix and store fuel in a container approved for gasoline.
 Mix fuel outdoors where there are no sparks or flames.

Wipe up any fuel spillage. Move 30 ft. away from refueling

site before starting engine. Slowly remove the fuel cap

after stopping engine. Do not smoke when refueling.
 Stop the engine and allow to cool before refueling or

storing the unit.
 Allow the engine to cool; empty the fuel tank and secure

the unit from moving before transporting in a vehicle.
 Wear your protective equipment and observe all safety

instructions. For units equipped with a clutch, be sure

the cutting attachment stops turning when the engine

idles. When the unit is turned off make sure the cutting

attachment has stopped before the unit is set down.

See Figure 8.

Engine lubricant has a major influence on engine perfor­mance and service life. This unit is shipped with a 20W50
engine lubricant to assist in the break-in period. For best
operating performance, continuing to use 20W50 engine
lubricant is recommended, however, SAE 30, 10W30, or
10W40 are all acceptable lubricants to use in this product.
Always use a 4-stroke engine lubricant that meets or exceeds
the requirements for API service classification SJ. Check
lubricant level before each use.

NOTE: Non-detergent or 2-stroke engine lubricants will
damage the engine and should not be used.

To add engine lubricant:

 Remove the cap and seal from lubricant bottle pro-

vided.

 Unscrew the oil cap/dipstick and remove.
 Using funnel provided, add entire bottle of engine lubricant

through oil fill hole.

 Reinstall the oil cap/dipstick and secure.

To check engine lubricant level:

 Set unit on a flat surface.
 Wipe dipstick clean and re-seat in hole; do not rethread.
 Remove dipstick again and check lubricant level. Lubricant

level should fall within the hatched area on the dipstick.

 If level is low, add engine lubricant until the fluid level rises

to the upper portion of the hatched area on the dipstick.

 Replace and secure the oil cap/dipstick.

WARNING:

To avoid burns from hot surfaces, never operate unit with
the bottom of the engine above waist level.

Hold the trimmer with your right hand on the rear handle
and your left hand on the front handle. Keep a firm grip with
both hands while in operation. Trimmer should be held at a
comfortable position with the rear handle about hip height.

Cut tall grass from the top down. This will prevent grass from
wrapping around the shaft housing and string head which
could cause damage from overheating. If grass becomes
wrapped around the string head, STOP THE ENGINE, dis­connect the spark plug wire, and remove the grass.

WARNING:

Always hold the string trimmer away from the body keep­ing clearance between the body and the product. Any
contact with the housing or string trimmer cutting head can
result in burns and/or other serious personal injury.

OPERATION

TO ADVANCE THE CUTTING LINE (REEL EASY
STRING HEAD)

Line advance is controlled by tapping the string head on
grass while running engine at full throttle.

 Run engine at full throttle.
 Tap the knob on ground to advance line. The line advances

each time the knob is tapped. Do not hold the knob on
the ground.

NOTE: The line trimming cut-off blade on the grass deflector
will cut the line to the correct length.

NOTE: If the line is worn too short you may not be able to
advance the line by tapping it on the ground. If so, stop the
engine and manually advance the line.

To advance the cutting line manually:

Stop the engine and disconnect the spark plug wire.
 Push the knob in while pulling on line(s) to manually

advance the line.

NOTE: Dual Spool™ Fixed Line Adaptor line cannot be ad-
vanced. To replace the line, refer to Installing Line in Dual
Spool™ Fixed Line Adaptor later in this manual.

CUTTING TIPS

See Figures 10 -11.

 Avoid hot surfaces by always keeping the tool away from

your body. (Proper operating position shown in figure 9.)

 Keep the trimmer tilted toward the area being cut; this is

the best cutting area.

 The curved shaft trimmer cuts when passing the unit from

right to left. The straight shaft trimmer cuts when passing
the unit from left to right. This will avoid throwing debris at
the operator. Avoid cutting in the dangerous area shown
in illustration.

 Use the tip of line to do the cutting; do not force string

head into uncut grass.

 Wire and picket fences cause extra line wear, even

breakage. Stone and brick walls, curbs, and wood may
wear line rapidly.

 Avoid trees and shrubs. Tree bark, wood moldings, siding,

and fence posts can easily be damaged by the line.

GRASS DEFLECTOR LINE TRIMMING CUT-OFF
BLADE

See Figure 12.

The trimmer is equipped with a line trimming cut-off blade
on the grass deflector. For best cutting, advance line until it
is trimmed to length by the cut-off blade. Advance the line
whenever you hear the engine running faster than normal,
or when trimming efficiency diminishes. This will maintain
best performance and keep the line long enough to advance
properly.

CLEANING THE EXHAUST PORT AND
MUFFLER

NOTE: Depending on the type of fuel used, the type and

amount of lubricant used, and/or your operating conditions, the
exhaust port, muffler, and/or spark arrestor screen may be­come blocked with carbon deposits. If you notice a power
loss with your gas powered tool, you may need to remove
these deposits to restore performance. We highly recom­mend that only qualified service technicians perform this
service.

SPARK ARRESTOR

The spark arrestor must be replaced every 50 hours or yearly
to ensure proper performance of your product. Spark arres­tors may be in different locations depending on the model
purchased. Please contact your nearest service dealer for
the location of the spark arrestor for your model.

IDLE SPEED ADJUSTMENT

See Figure 23.

If the cutting attachment turns at idle, the idle speed screw
needs adjusting on the engine. Turn the idle speed screw
counterclockwise to reduce the idle RPM and stop the cut­ting attachment movement. If the cutting attachment still
moves at idle speed, contact a service dealer for adjustment
and discontinue use until the repair is made.

WARNING:

The cutting attachment should never turn at idle. Turn
the idle speed screw counterclockwise to reduce the
idle RPM and stop the cutting attachment, or contact a
service dealer for adjustment and discontinue use until
the repair is made. Serious personal injury may result
from the cutting attachment turning at idle.

CLEANING AIR FILTER SCREEN

 Replace the air filter cover by inserting the tabs on the

bottom of the cover into the slots on the air filter base;
push the cover up until it latches securely in place.

FUEL CAP

WARNING:

Check for fuel leaks. A leaking fuel cap is a fire hazard
and must be replaced immediately. If you find any leaks,
correct the problem before using the product. Failure
to do so could result in a fire that could cause serious
personal injury.

The fuel cap contains a non-serviceable filter and a check
valve. A clogged fuel filter will cause poor engine perfor­mance. If performance improves when the fuel cap is loos­ened, check valve may be faulty or filter clogged. Replace
fuel cap if required.

SPARK PLUG REPLACEMENT

This engine uses an Champion RY4C spark plug with
.025 in. electrode gap. Use an exact replacement and re­place annually.

CHANGING ENGINE LUBRICANT

See Figure 26.

ADJUSTING CAMSHAFT-TO-ROCKER ARM
CLEARANCE

See Figures 27 - 30.

Inspect the camshaft-to-rocker arm clearance after every
25 hours of operation. This should be done in a clean, dust­free environment.

NOTE: This procedure requires partial disassembly of the
engine. If you are unsure if you are qualified to perform this
operation, take the unit to an authorized service center.

 Stop the engine and disconnect the spark plug wire. Allow

the engine to cool completely before proceeding.

 Remove the screw from the top engine cover. Remove

engine cover and set aside.

 Using a Torx screwdriver, remove the screw from the

rocker arm cover. Remove the cover and set aside.

 Position camshaft by pulling the recoil starter grip just

until the deep hole in the camshaft gear is located at the
6 o-clock position as shown.

 Place the feeler gauge under each rocker arm and mea-

sure the gap. The gap should be between .006 in. (0.15
mm) and .008 in. (0.20 mm) for both rocker arms.

NOTE: Use a standard automotive feeler gauge. The .006

in. (0.15 mm) feeler gauge should slide between the rocker
arm and valve stem with a slight amount of resistance
but without binding. The 0.008 in. (0.20 mm) feeler gage
should not slide between the rocker arms and the cam
lobes — it should be held tight.

 If the valve clearance is not between .006 in. (0.15 mm)

and .008 in. (0.20 mm), the clearance should be adjusted
as follows:

 While holding a wrench on the flats of the adjusting nut

with one hand, loosen the retaining nut with a second
wrench as shown. Take care not to loosen the stud.

 Rotate the adjusting nut until it touches the feeler gauge.

Once the gap setting is correct, hold the wrench on
the flats of the adjusting nut and retighten the retaining
nut securely.

 Adjust the second rocker arm, if necessary.
 Replace the rocker arm cover and screw; tighten

securely.

 Replace the top engine cover and screw; tighten

securely.

WARNING:

Ensure all engine cover and all engine parts are completely
and properly reassembled before starting engine. Failure
to correctly reassemble engine may result in serious injury
or property damage.

STORING THE PRODUCT

 Clean all foreign material from the product. Store idle unit

indoors in a dry, well-ventilated area that is inaccessible

to children. Keep away from corrosive agents such as

garden chemicals and de-icing salts.
 When storing the product vertically, do so with the engine

up to avoid hydraulically locking the engine due to oil

entering the combustion chamber.
NOTE: If the engine/starter rope becomes locked after

storage, place the unit flat on the ground in the upright

position to allow the engine oil to slowly migrate back

into the engine’s oil reservoir.
 Abide by all ISO and local regulations for the safe storage

and handling of gasoline.

When storing 1 month or longer:

 Drain all fuel from tank into a container approved for

gasoline. Run engine until it stops.

HIGH ALTITUDE ENGINE OPERATION

Please have an authorized service center adjust this engine
if it is to be run above 2000 feet. Failure to do so may result
in poor engine performance, spark plug fouling, hard start­ing, and increased emissions. Carburetor adjustment by
an authorized service center will improve performance and
allow that this engine meets EPA (Environmental Protection
Agency) and California ARB (Air Resources Board) emis­sion standards. An engine adjusted for high altitudes can
not be run at 2000 feet or lower. In doing so, the engine will
overheat and cause serious engine damage. Please have
an authorized service center restore high altitude modified
engines to the original factory specification before operating
below 2000 feet.
