Unpacking instructions (Figure 1)
The mower was fully assembled at the factory.
When the mower was put in the carton, the
handle was put in the storage position. To put
the handle in the operating position, follow the
steps below.
1. Remove the mower from the carton.
2. Put the
lower handle (1) in the operating
position. Make sure the lower handle (1) is
between the locking tabs.
3. Put the upper handle (3) in the operating
position. Tighten the knobs (4) .
CAUTION: Be careful when you fold or
raise the handle. Do not damage the
cables. A cable that is bent will not work
correctly. Before you use the unit, replace
a bent or damaged cable.
4. (Figure 7) To attach the recoil-start grip (1)
to the rope guide (2), twist the rope through
the rope guide (2) mounted on the right side
of the handle.
NOTE: If you cannot attach the recoil-start
grip because the rope is too short, hold the
engine stop lever against the handle. Slowly
pull the recoil-start grip.
How To Adjust The Handle Height
(Figure 2) The handle bracket has two
assembly positions. A HIGH and a LOW
position. The HIGH position will raise the handle
approximately 10.16cm.
1.
(Figure 4) Remove the knobs (4) and bolts
(5) from the right and left handle brackets
(6).
2. (Figure 5) To raise the handle, mount the
lower handle (1) in the HIGH (2) position.
3. (Figure 6) To lower the handle, mount the
lower handle (1) in the LOW (3) position.
4. (Figure 4) Attach the lower handle (1) to the
handle brackets (6) with the knobs (4) and
bolts (5) .
IMPORTANT: Make sure the hooks (3), are
mounted on the rear door pivot rod (4).
How To Prepare The Engine
Note: Engine does not contain OIL or PET-
ROL.
WARNING: Follow the engine
manufacturer’s instructions for the
type of petrol and oil to use. Al-
ways use a safety petrol container. Do not
smoke when adding petrol to the engine.
When inside an enclosure, do not fill with
petrol. Before you add petrol, stop the en-
gine. Let the engine cool for several min-
utes.
See the engine manufacturer’s instructions for
the type of petrol and oil to use. Before you use
the unit, read the information on safety,
operation, maintenance, and storage.
How To Discharge Out The Side
(Figure 8)
1. Stop the engine.
2. Loosen the
wingnut (1).
3. Move the chute deflector (2) to the open
SIDE DISCHARGE position.
4. Tighten the wingnut (1).
5. Remove the grass bag. Make sure the rear
door is completely closed.
How To Mulch (Figure 9)
1. Stop the engine.
2. Loosen the
wingnut (1).
3. Move the chute deflector (2) to the closed
MULCH position.
4. Tighten the wingnut (1) .
5. Remove the grass bag. Make sure the rear
door is completely closed.
Mulching finely cuts the grass so that the grass
can be easily recycled. Because the nutrients
are returned to the soil, the lawn will need less
fertilizer. To correctly mulch the lawn, follow the
tips below.
S
The grass must be dry. If the grass is wet, it will
be difficult to cut and cause heavy clumps of
grass.
S
The grass must not be too tall. The maximum
height to effectively cut is 4 1/2 inches. Set the
height adjusters so that only the top third of the
grass is cut.
S
If the grass is more than 4 1/2 inches high, two
mowings will be necessary. For the first mow-
ing, set the height adjusters in the highest posi-
tion. Then, lower the height adjusters for the
second mowing.
S
Keep a sharp edge on the blade. A blade that
is not sharp will cause the ends of the grass to
become brown.
S
Clean the underside of the mower housing.
Grass and other debris can keep the mower
from working correctly.
If the quality of cut is marginal, try the follow-
ing:
S
Set the height adjusters at a higher cutting
height.
S
Cut the grass more frequently.
S
Operate the mower at a slower ground speed.
S
Overlap the cutting swaths instead of cutting a
full swath with each pass.
S
Mow across the marginal areas a second time.
OPERATION
NOTE: Illustrations and pictorials begin on
page 2.
Engine Stop Lever (Figure 10)
Release the engine stop lever (1) and the
engine and the blade will automatically stop. To
run the engine, hold the engine stop lever (1) in
the Operating position (2)
Before you start the engine, operate the engine
stop lever (1) several times. Make sure the
cable moves easily.
How To Stop The Engine (Figure 10)
To stop the engine, release the engine stop
lever (1) . Disconnect the wire from the spark
plug to prevent the engine from starting.
If the engine will not stop, hold a screwdriver
against the spark plug and against the engine
cooling fins. The spark will go to ground and the
engine will stop. Before you start the engine,
check the engine stop cable. Make sure the
engine stop cable is assembled correctly. Before
you operate the unit, replace a bent or damaged
engine stop cable.
How To Start The Engine
WARNING: The blade will rotate
when the engine runs.
1. Check the oil.
2. Fill the fuel tank with regular unleaded petrol.
See “How To Prepare The Engine”.
3. Make sure the spark plug wire is connected
to the spark plug.
4. (Figure 12) Some models have a primer
button (1) on the front or side of the engine.
Push the primer button (1). . Every time you
push the primer button (1) , wait two sec-
onds. For the number of times required to
push the primer button (1), see the engine
manufacturer’s instructions.
NOTE: Do not use the primer button to
start a warm engine.
5. (Figure 13) Stand behind the mower. Use
one hand to hold the engine stop lever (1)
in the operating position as shown. Use the
other hand to hold the recoil-start grip (2).
6. Rapidly pull the recoil-start grip (2). Slowly
return the recoil-start grip (2).
7. If the engine does not start in 5 or 6 tries,
See the “Trouble Shooting Chart” Instruc-
tions.
How To Operate The Mower
WARNING: Check the condition of
the grass bag for wear or deteriora-

the parts only with approved factory re-
placement parts. For replacement parts,
see the parts list in this book.
To completely fill the grass bag, operate the
engine with the throttle control in the FAST
position.
