AND INFORM OTHERS.
EXERCISE GREATCARE AND FOLLOW THE ADVICE GIVEN TO
AVOID POTENTIALLYHAZARDOUS SITUATIONS.
The Harrier 48 is perfectly safe if used correctly. Failure to observe the
following simple precautions may result in serious injury.

Training:

Read the instructions carefully. Ensure that you are familiar with the controls and the
proper use of the equipment. Learn how to stop the mower quickly in an emergency.

Never allow children or people unfamiliar with these instructions to use the mower.

Never mow while people, especially children, or pets are nearby.

or their property.

Preparation:

SAFETY PRECAUTIONS

1.5

While mowing, always wear substantial footwear and long trousers. Do not operate the
equipment when barefoot or wearing sandals.

Thoroughly inspect the area where the mower is to be used and remove all objects which may
be thrown by the machine.

WARNING: Petrol is highly flammable.

- Store fuel in containers specifically designed for this purpose.

- Refuel outdoors only and do not smoke while refuelling.

- Add fuel before starting the engine. Never remove the cap from the fuel tank or add petrol
while the engine is running or when the engine is hot. Allow the engine to cool for at least 2
minutes before refuelling.

- Do not attempt to start the engine if petrol is spilled or a smell of petrol is present. Move
the mower away from the area of spillage and avoid creating any source of ignition until
petrol vapours have dissipated.

- Always use fresh fuel. Stale fuel can block the carburettor and cause leakage.

485101MT210999A

1.6

SAFETY PRECAUTIONS

1.6

SAFETY PRECAUTIONS

- Replace fuel tank and container caps securely.

- Replace faulty exhaust mufflers.

Always ensure that the mower is in a safe operating condition. Frequently check all nuts,
bolts and screws for tightness. Use only genuine Hayter replacement parts.

A damaged cutterbar or loose fixing screws are major hazards. Before use, visually inspect
the cutting mechanism to ensure that it is in good condition. A damaged cutterbar must be
replaced immediately with a genuine Hayter replacement part. Acutterbar which is slightly
worn can be re-sharpened. Ensure that both cutting edges are re-sharpened equally to main­tain balance. An unbalanced cutterbar may cause serious damage to your machine.
Refer to “Maintenance”.

Operation:

Do not operate the engine in a confined space where dangerous carbon monoxide fumes can
collect.

Always pull the starter cord slowly until resistance is felt. Then pull the cord rapidly to avoid
kickback and prevent hand or arm injury.

Mow only in daylight or good artificial light.

Continued.

Avoid using the mower on wet grass, where feasible.

Always be sure of your footing on slopes.

Walk, never run.

Mow across the face of slopes, never up and down.

Exercise extreme caution when changing direction on slopes.

Do not mow excessively steep slopes.

Use extreme caution when reversing or pulling the mower towards you.

Stop the engine if the mower has to be tilted for transportation when crossing surfaces other
than grass and when transporting the mower to and from the area to be mowed.

Never operate the mower unless the guards are securely in position and in good condition.

485101MT210999A

1.7

SAFETY PRECAUTIONS

1.7

SAFETY PRECAUTIONS

Do not change the engine governor settings or overspeed the engine.

Disengage the rear roller drive clutch before starting the engine.

Start the engine carefully, with feet well away from the cutterbar.

Do not tilt the mower when starting the engine.

Do not put hands or feet near or under rotating parts.

Never pick up or carry a mower while the engine is running.

Stop the engine and disconnect the spark plug lead:

- Before clearing blockages or unclogging the discharge chute.

- Before cleaning / checking or working on the mower.

- After striking a foreign object. Inspect the mower for damage and make repairs
before restarting and operating the mower.

- If the mower starts to vibrate abnormally (check immediately).

Stop the engine:

Continued.

- Whenever you leave the mower.

- Before refuelling.

Never lift the deflector plate whilst the mower is in operation.

Never touch the engine muffler / muffler guard or cooling fins when the engine is hot.

WARNING: THE CUTTERBAR CAN CONTINUE TO ROTATE
AFTER THE ENGINE IS SWITCHED OFF

SAFETY PRECAUTIONS

SAFETY PRECAUTIONS

Maintenance and Storage:

Keep all nuts, bolts and screws tight to ensure that the equipment is in safe operating
condition.

Frequently check fuel lines and fittings for cracks or leaks and replace if necessary.

Never check for a spark with the spark plug removed. (Use an approved tester).

Never crank the engine with the spark plug removed. If the engine is flooded, move the
throttle to the ‘fast’ position and crank the engine until it starts.

Never strike the flywheel with a hammer or hard object as this may cause the flywheel to
shatter in operation. Always use the correct tools to service the engine.

Never operate the engine without a muffler guard. Inspect the muffler periodically and
replace if worn or leaking.

Never start the engine with the air-cleaner or air-cleaner cover removed.

Never store the mower with petrol in the tank within an enclosed area where fumes may reach
an open flame or spark.

Allow the engine to cool before storing in any enclosure.

To reduce the fire hazard, keep the engine, muffler, cooling fins and petrol storage area free
of grass, leaves, or excessive grease.

Continued.

Check the grassbag frequently for wear or deterioration.

Replace worn or damaged parts for safety.

If the fuel tank has to be drained, it is essential that this be done outdoors.

missing contact, your local Hayter dealer.

Assemble the handlebar: Unscrew the handlebar securing
knobs sufficiently to allow the handlebar to be pivoted.
Move the engine stop lever away from the engine to avoid
damage and unfold the handlebar to its operating position.
Ensure that both Knobs are on the outside of the handlebar
and the cable guide is positioned as shown. Tighten to
secure handlebar in position.

IMPORTANT - PREVENT DAMAGE : When unfold­ing the handlebar, take care to ensure that the controls
and cables do not become damaged. Always replace
damaged controls and cables before using the mower.

Adjust height of handlebar: Unscrew the two larger

Knobs at base of handlebar sufficiently to allow it to be
moved to the upper, middle or lower position. Secure in

ASSEMBLING THE MOWER FOR THE FIRST TIME

Check blade brake / clutch controls: Operate the blade

stop lever (A) several times, to ensure the lever moves
freely. Hold the lever against the handlebar in position (1)
and check that it returns to position (2) when released.

Use the right hand to hold the blade stop lever against the
handlebar (1) and use the left hand to push the blade clutch
lever (B) to the ‘engaged’ position (3). Remove the left
hand and the blade clutch lever should return to position (4),
leaving the blade drive clutch engaged.

automatically returns to position (2). There should be an
audible ‘clunk’ to indicate that the blade drive clutch has
disengaged.

Check throttle lever operation: Operate the throttle lever
several times and ensure that the cable moves freely whilst
operating the engine throttle mechanism. Slight resistance
should be felt when the lever moves to the ‘choke’ position.
