Slope Operation
Slopes are a major factor related to slip and fall accidents which
can result in severe injury. Operation on slopes requires extra
caution. If you feel uneasy on a slope, do not dethatch it. For
your safety, use the slope gauge included as part of this manual
to measure slopes before operating this unit on a sloped or hilly
area. If the slope is greater than 15 degrees, do not dethatch it.
Do:
Dethatch across the face of slopes; never up and down.1.
Exercise extreme caution when changing direction on
slopes.
Watch for holes, ruts, rocks, hidden objects, or bumps2.
which can cause you to slip or trip. Tall grass can hide
obstacles.
Always be sure of your footing. A slip and fall can cause3.
serious personal injury. If you feel you are losing your
balance, release the blade control bail immediately, and the
blade will stop rotating within several seconds
Do Not:
Do not dethatch near drop-offs, ditches or embankments,1.
where you could lose your footing or balance.
Do not dethatch slopes greater than 15 degrees as shown2.
on the slope gauge.
Do not dethatch wet grass. Unstable footing could cause3.
slipping.
Children
Tragic accidents can occur if operator is not alert to1.
presence of children. Children are often attracted to
outdoor power equipment. They do not understand the
dangers. Never assume that children will remain where you
last saw them.
Keep children out of the work area and under watchful care2.

Use extreme care when approaching blind corners,5.
doorways, shrubs, trees, or other objects that may obscure
your vision of a child who may run into the dethatcher.
Keep children away from hot or running engines. They can6.
suffer burns from a hot muffler.
Never allow children under 14 years old to operate the7.
dethatcher. Children 14 years old and over should read and
understand operation instructions and safety rules in this
manual and should be trained and supervised by an adult.
Service
Safe Handling Of Gasoline:
To avoid personal injury or property damage use extreme1.
care in handling gasoline. Gasoline is extremely flammable
and the vapors are explosive. Serious personal injury can
occur when gasoline is spilled on yourself or your clothes
which can ignite. Wash your skin and change clothes
immediately.

ground away from your vehicle before filling.
Remove gas-powered equipment from the truck or4.

then refuel such equipment on a trailer with a portable
container, rather than from a gasoline dispenser nozzle.
Keep the nozzle in contact with the rim of the fuel tank or5.

Replace gasoline cap and tighten securely.10.
If gasoline is spilled, wipe it off the engine and equipment.11.
Move unit to another area. Wait 5 minutes before starting
engine.
Never store the machine or fuel container near an open12.

heater, furnace, clothes dryer, or other gas appliances.
To reduce fire hazard, keep dethatcher free of grass, leaves,13.
or other debris build-up. Clean up oil or fuel spillage and
remove any fuel soaked debris.
Allow dethatcher to cool at least 5 minutes before storing.14.
General Service:
Never run an engine indoors or in a poorly ventilated area.1.
Engine exhaust contains carbon monoxide, an odorless
and deadly gas.
Before cleaning, repairing, or inspecting, make certain the 2.
blades and all moving parts have stopped. Disconnect the
spark plug wire and ground against the engine to prevent
unintended starting.
Check the blade and engine mounting fasteners at3.
frequent intervals for proper tightness. Also, visually
inspect blades for damage (e.g., bent, cracked, worn)
Replace blades with the original equipment manufacture’s
(O.E.M.) blade only. Use of parts which do not meet the
original equipment specifications may lead to improper
performance and compromise safety!
Dethatcher blades may be sharp and can cut. Wrap the4.
blade or wear gloves, and use extra caution when servicing
them.
Keep all nuts, bolts, and screws tight to be sure the5.
equipment is in safe working condition.
Never tamper with safety devices. Check their proper6.
operation regularly.
After striking a foreign object, stop the engine, disconnect7.
the spark plug wire and ground against the engine.
Thoroughly inspect the dethatcher for any damage. Repair
the damage before starting and operating the dethatcher.
For safety protection, frequently check components8.
and replace immediately with original equipment
manufacturer’s (O.E.M.) parts only. Use of parts which do
not meet the original equipment specifications may lead to
improper performance and compromise safety!
Do not change the engine governor setting or overspeed9.
the engine. The governor controls the maximum safe
operating speed of the engine. Do not crank engine with
spark plug removed.
Check fuel line, tank, cap, and fittings frequently for cracks10.
or leaks. Replace if necessary.
Maintain or replace safety and instruction labels, as11.
necessary.
Observe proper disposal laws and regulations. Improper 12.
disposal of fluids and materials can harm the environment.
Do not modify engine
To avoid serious injury or death, do not modify engine in any
way. Tampering with the governor setting can lead to a runaway
engine and cause it to operate at unsafe speeds. Never tamper
with factory setting of engine governor.
Notice Regarding Emissions
Engines which are certified to comply with California and federal
EPA emission regulations for SORE (Small Off Road Equipment)
are certified to operate on regular unleaded gasoline, and
may include the following emission control systems: Engine
Modification (EM), Oxidizing Catalyst (OC), Secondary Air
Injection (SAI) and Three Way Catalyst (TWC) if so equipped.
Spark Arrestor
WARNING: This machine is equipped with an
internal combustion engine and should not be used
on or near any unimproved forest-covered, brush
covered or grass-covered land unless the engine’s
exhaust system is equipped with a spark arrestor
meeting applicable local or state laws (if any).
If a spark arrestor is used, it should be maintained in effective
working order by the operator. In the State of California the
above is required by law (Section 4442 of the California Public
Resources Code). Other states may have similar laws. Federal laws
apply on federal lands.
A spark arrestor for the muffler is available through your
nearest engine authorized service dealer or contact the service
department, P.O. Box 361131 Cleveland, Ohio 44136-0019.

Blade Control Bail
Located on the upper handle, the blade control handle is used to
engage and disengage drive to the cutting blades. Squeeze the
control handle against the upper handle to engage the blades;
release it to disengage.
Depth Control Lever
The depth control lever raises and lowers the cutting blades.
Use the 1-setting for transportation, settings 2 through 5 for
dethatching. Settings 3, 4, and 5 are not needed until the blades
are too worn to be effective on setting 2. Optimum cutting depth
is ¹⁄8of an inch.
Bail Interlock
The bail interlock locks the blade control handle in place to
prevent unwanted engaging of the cutting blades.

NOTE: The blade control bail does not need to be engaged in
order to start the engine.
Using the Dethatcher
Dethatch the lawn once in the spring and once in the fall to clear
dead and/or dying grass from the lawn, and to allow more air to
flow through the ground. Grass should be 2 ½ inches high when
dethatched. After dethatching, fertilize and water the lawn to
encourage quicker growth.
Be sure lawn is clear of stones, sticks, wire, or other objects which
could damage dethatcher or engine. Such objects could be
accidently thrown by the dethatcher in any direction and cause
serious personal injury to the operator and others.
Release bail interlock and engage blade control bail to start1.

Set the height adjustment lever to the appropriate slot; 22.
being the highest setting, 5 being the lowest. Settings 3, 4,
and 5 are not needed until the blades are too worn to be
effective on setting 2. Optimum cutting depth is ¹⁄8of an
inch. See Fig. 5-2.
CAUTION: Do not set the cutting blades too deep;
doing so will shorten the life of the blade drive belt.
If dethatcher becomes stuck during use, gently push•
downward on handle to raise front wheels
Do not drive over discarded thatch as this creates an•
uneven cutting height
When dethatching, leave approximately eight inches of•
soil between the first and second dethatching paths; rake
dethatched grass from first and second path then dethatch
between the two paths.
When turning, pivot dethatcher on back two wheels with•
blades disengaged.
CAUTION: Do not make sharp turns with cutting
blades engaged. Doing so may damage the blades.
Transporting the Dethatcher
Set the height adjustment lever to the 1-setting.1.
Push to new location.2.
