Filling the Fuel Tank
For best results, use clean, fresh, lead-free petrol with
an octane rating of 87 or higher. To ensure freshness,
purchase only the quantity of petrol that you expect to
use in 30 days. Using unleaded petrol results in fewer
combustion deposits and longer engine life. You may
use leaded petrol if unleaded petrol is not available.
In certain conditions, petrol is extremely
flammable and highly explosive. A fire or
explosion from petrol can burn you and others
and can damage property.
• Fill the fuel tank outdoors, in an open area,
and when the engine is cold. Wipe up any
petrol that spills.
Important: Do not add oil to the petrol.
Important: Do not use petrol that has been stored
since the last mowing season or longer.
• Do not fill the fuel tank completely full. Add
petrol to the fuel tank until the level is 1/4
to 1/2 in. (6 to 13 mm) below the bottom of
the filler neck. This empty space in the tank
allows the petrol to expand.
When fueling, under certain circumstances, a
static charge can develop, igniting the petrol. A
fire or explosion from petrol can burn you and
others and damage property.
• Never smoke when handling petrol, and stay
away from an open flame or where a spark
may ignite the petrol fumes.
• Store petrol in an approved fuel container
and keep it out of the reach of children.
• Always place petrol containers on the
ground and away from your vehicle before
filling.
• Never buy more than a 30-day supply of
petrol.
• Do not fill petrol containers inside a vehicle
or on a truck or trailer bed because interior
carpets or plastic truck bed liners may
insulate the container and slow the loss of
any static charge.
1. Clean around the fuel tank cap (Figure 11).
• When practical, remove petrol-powered
equipment from the truck or trailer and
refuel the equipment with its wheels on the
round.
• If this is not possible, then refuel such
equipment on a truck or trailer from
a portable container, not from a petrol
dispenser nozzle.
• If you must use a petrol dispenser nozzle,
keep the nozzle in contact with the rim of
the fuel tank or container opening at all
times until fueling is complete.
Use a fuel stabilizer/conditioner regularly during
operation and storage. A stabilizer/conditioner cleans
the engine during operation and prevents gum-like
varnish deposits from forming in the engine during
periods of storage.

2. Remove the cap from the tank.
Important: Do not use fuel additives other than
a fuel stabilizer/conditioner. Do not use fuel
stabilizers with an alcohol base such as ethanol,
methanol, or isopropanol.
3. Fill the fuel tank with unleaded petrol to within 1/4
to 1/2 inch (6 to 13 mm) from the top of the tank.
Do not fill into the filler neck.

Release the traction control bar.
Important: When you release the blade control
bar, the blade should stop within 3 seconds. If it
does not stop properly, stop using your mower
immediately and contact an Authorized Service
Dealer.
Checking the Blade Brake
Clutch
Check the blade control bar before each use to ensure
that the blade brake clutch system is operating properly.
Operating the Traction Drive
You can use the grass bag to perform an additional test
to check the blade brake clutch mechanism:
Engaging the Traction Drive
1. Install the empty grass bag on the discharge tunnel.
2. Start the engine.
1. Release the traction control bar (Figure 16).
3. Pull the blade control bar to the normal blade
engaged position. The bag should begin to inflate,
indicating that the blade is engaged and rotating.
4. Release the blade control bail. If the bag does not
immediately deflate, it indicates that the blade is still
rotating. The blade brake clutch mechanism may
be deteriorating, and, if ignored, could result in an
unsafe operating condition. Have the lawn mower
inspected and serviced by an Authorized Service
Dealer.
Figure 16
If the blade brake clutch system is inoperative,
the blade will continue to rotate when you
release the blade control bail. Contact with
blade could occur, causing serious injury.
2. Move the ground speed control lever to the desired
gear position.
• Check the blade brake clutch operation
before each use.
3. Squeeze the traction control bar against the handle
• Never use a mower equipped with a blade
brake clutch that has an inoperative safety
system.
• Take your mower to an Authorized Service
Dealer for repair if the safety system fails to
operate properly.

Mowing with the Grass Bag
Operating a mower with its engine running at
a speed greater than the factory setting can
cause the mower to throw a part of the blade or
engine into the operator’s or bystander’s area
and result in serious personal injury or death.
A worn grass bag could allow small stones
and other similar debris to be thrown in the
operator’s or bystander’s direction and result in
serious personal injury or death to the operator
or bystanders.
– Do not change the engine speed setting.
– If you suspect the engine speed is faster
than normal, contact an Authorized Service
Dealer.
Check the grass bag frequently. If it is damaged,
install a new Hayter replacement bag.
• Clean the air filter frequently. Mulching stirs up
more clippings and dust which clogs the air filter
and reduces engine performance.
Operating Tips
General Tips
Cutting Grass
• Maintain a sharp blade throughout the cutting
season. Periodically file down nicks on the blade.
• Grass grows at different rates at different times
of the year. In the summer heat, it is best to cut
grass at the 2-1/2 inch (64 mm), 3 inch (76 mm),
or 3-1/2 inch (89 mm) cutting height settings. Cut
only about a third of the grass blade at a time. Do
not cut below the 2-1/2 inch (64 mm) setting unless
the grass is sparse or it is late fall when grass growth
begins to slow down.
• Replace the blade when necessary with an original
Hayter replacement blade.
• Mow only dry grass or leaves. Wet grass and leaves
can build up and clog in the chute or cause the
engine to stall.
• When cutting grass over 6 inches (15 cm) tall, first
mow at the highest cutting height setting and walk
slower; then mow again at a lower setting for the
best lawn appearance. If the grass is too long and
the leaves clump on top of the lawn, the mower may
clog and cause the engine to stall.
Wet grass or leaves can cause serious injury if
you slip and contact the blade.
Mow only in dry conditions.
• Alternate the mowing direction. This helps disperse
the clippings over the lawn for even fertilization.
• Clean under the mower housing after each mowing.
See Cleaning under the Mower Housing.
If the finished lawn appearance is unsatisfactory, try
one or more of the following:
• Keep the engine in good running condition.
• Sharpen the blade.
• Set the engine speed to the fastest position for the
best cutting results.
• Walk at a slower pace while mowing.
• Raise the cutting height on your mower.
• Cut the grass more frequently.
• Overlap cutting swaths instead of cutting a full
swath with each pass.
• Set the cutting height on the front wheels one notch
lower than the rear wheels. For example, set the
front wheels at 2-1/2 inches (64 mm) and the rear
wheels at 3 inches (76 mm).
Cutting Leaves
• After cutting the lawn, ensure that half of the lawn
shows through the cut leaf cover. You may need to
make more than one pass over the leaves.
15
Download from Www.Somanuals.com. All Manuals Search And Download.
• For light leaf coverage, set all the wheels at the same
cutting height setting.
• If there are more than 5 inches (12.7 cm) of leaves
on the lawn, set the front cutting height 1 or 2
notches higher than the rear cutting height. This
makes it easier to feed the leaves under the mower
housing.
• Slow down your mowing speed if the mower does
not cut the leaves finely enough.
• If you mow over oak leaves, you can add lime to
the grass in the spring to reduce the acidity of the
oak leaves.

Do not overtighten the blade brake cable.
Overtightening the blade brake cable could
prevent the blade brake from contacting the
brake drum when you release the control bar.
If the blade brake does not contact the brake
drum, the blade will not stop rotating, which
could cause serious personal injury.
• Each time you adjust the brake cable, ensure
that the brake stops the blade in 3 seconds
or less.
• If the blade does not stop rotating in 3
seconds or less, bring the mower to an
Authorized Service Dealer for inspection
and repair.

Blade Maintenance
Maintaining the Cutting Blade
Always mow with a sharp blade. A sharp blade cuts
cleanly and without tearing or shredding the grass blades.
Complete the following procedure before
inspecting, removing, or installing the blade:
Figure 36
3. Wear
1. Stop the engine and wait for all moving parts to stop.
2. Disconnect the wire from the spark plug (Figure 12).
1. Sail
2. Flat part of the blade
4. Slot formed
3. Drain the petrol from the fuel tank; refer to
Emptying the Fuel Tank and Cleaning the Fuel Filter.
Note: For the best performance, install a new blade
before the cutting season begins. During the year, file
down any small nicks to maintain the cutting edge.
4. Tip the mower onto its right side (Figure 35).
A worn or damaged blade can break, and a
piece of the blade could be thrown into the
operator’s or bystander’s area, resulting in
serious personal injury or death.
• Inspect the blade periodically for wear or
damage.
• Replace a worn or damaged blade.
Removing the Blade
Figure 35
Grasp the end of the blade using a rag or a thickly
padded glove. Remove the blade nuts, the anti-scalp cup,
and the blade (Figure 35).

2. Blade nuts
3. Anti-scalp cup
Sharpening the Blade
Inspecting the Blade
File the top side of the blade to maintain its original
cutting angle (Figure 37A) and inner cutting edge radius
(Figure 37B). The blade will remain balanced if you
remove the same amount of material from both cutting
edges.
Service Interval: Before each use or daily
Carefully examine the blade for sharpness and wear,
especially where the flat and the curved parts meet
(Figure 36A). Because sand and abrasive material can
wear away the metal that connects the flat and curved
parts of the blade, check the blade before using the
mower. If you notice a slot or wear (Figure 36B and
Figure 36C), replace the blade; refer to Removing the
Blade.
Figure 37
1. Sharpen at this angle only. 2. Maintain the original radius

Cleaning
1. Check the balance of the blade by placing the center
hole of the blade over a nail or screwdriver shank
clamped horizontally in a vise (Figure 38).
Cleaning under the Mower
Housing
To ensure the best performance, keep the underside of
the mower housing clean.
Washing Method
Figure 38
Service Interval: Before each use or daily
1. Position the mower on a flat concrete or asphalt
surface near a garden hose.
Note: You can also check the balance using a
commercially manufactured blade balancer.
2. Start the engine.
2. If either end of the blade rotates downward, file that
end (not the cutting edge or the end near the cutting
edge). The blade is properly balanced when neither
end drops.
3. Hold the running garden hose at handle level and
direct the water to flow on the ground just in front
of the right rear tyre (Figure 39).
Installing the Blade
1. Install a sharp, balanced Hayter blade, the anti-scalp
cup, and the blade nuts. The sail of the blade must
point toward the top of the mower housing for
proper installation. Torque the blade nuts to 23 to
27 ft-lb (32 to 37 N-m).
Figure 39
1. Right rear wheel
2. Return the mower to its operating position.
3. Connect the wire to the spark plug.

clippings. Let the water run until you no longer see
clippings being washed out from under the housing.
4. Stop the engine and wait for all moving parts to stop.
5. Turn off the garden hose.
6. Start the mower and let it run for a few minutes
to dry out the moisture on the mower and its
components.
Scraping Method
If washing does not remove all debris from under the
mower, scrape it clean.
