SAFETY INSTRUCTIONS
WARNING
The safety of user and others involved. Personal injury may result if
information is disregarded.
• Inspect the area where the equipment is to be used and remove all stones, sticks, wire, bones
and other foreign, hard objects before mowing; they could be thrown by the blade.
• Never mow while barefoot or wearing open toe sandals or thongs.
Wear long trousers and heavy-duty shoes. It is advisable to wear suitable eye and hearin
protection.
• Read the Owner’s Manual carefully and know the controls. Learn how to stop the engine quickly
in an emergency.
• Stop the engine and disconnect the spark plug lead before attempting to clear blockages,
checking or working on the mower.
• Never attempt to adjust cutting height with the engine running.
• Never operate the equipment in wet grass, always be sure of your footings, keep a rm grip on
the handles and walk, never run and never walk backwards while cutting grass.
• Check all nuts, bolts and screws before starting. Always be sure your mower is in a safe
operating condition. Use only replacement parts made or guaranteed by Talon Tools.
• Refuel outdoors only. Do not smoke while refueling engine. Add fuel before starting the engine.
Never remove fuel cap with engine running or add petrol while the engine is running. If petrol is
spilt, do not attempt to start the engine. Clean all spilt fuel and move the mower away from the
spilled area. Avoid creating any source of ignition until petrol vapours have dissipated.
• Replace worn or damaged blades, as worn blades and worn bolts are major hazards.
• Mow only in good daylight.
• Do not operate the engine in a conned space where exhaust fumes can collect, as they can be
lethal.
• Do not put hands or feet near or under rotating parts. Always keep clear of the blades and
discharge opening.
• Stop the engine whenever you leave the mower even for a moment, before cleaning and when
making any adjustments or inspections.
• Mow across the face of slope, never up and down. Exercise extreme caution when changing
direction on slopes. Do not mow excessively steep slopes.
• Stop the engine when crossing gravel driveways, walks or roads.
• Start the engine carefully with feet well away from the blades.
• Store fuel in a cool place in an approved container specically designed for the purpose. In
general, plastic containers are unsuitable.

AU
• Stop the engine and disconnect the spark plug lead before inspecting the mower if:
(a) the mower begins to vibrate abnormally, or
(b) after striking a foreign object.
• Check the catcher for wear and tear, and replace any worn or broken parts.
• To reduce re hazard, keep the engine free of grass, leaves and any spilt fuel.
• Shut the engine off and wait until the blades come to a complete stop before removing the
catcher or un-clogging the chute.
• Never pick up or carry a mower when it is operating.
• Replace worn or faulty silencers.
• Before using, always visually inspect to see that blades, blade bolts and cutter assembly
are not worn or damaged. Replace worn or damaged blades and bolts in sets to preserve
balance.
• Do not mow whilst people, especially children, or pets are in the mowing area.
• Do not allow children or people unfamiliar with these instructions to use the mower.
• Store the mower in a well-ventilated room away from naked ames such as may be found
in hot water heaters.
• Do not over-speed the engine or alter governor settings. Excessive speed is dangerous and
shortens mower life.
• Turn the fuel off at the conclusion of mowing and reduce the throttle setting during engine
run-out.
• Never cut grass while walking backwards.
• Walk, never run.
• Never use the mower unless the grass catcher, or guards provided, are in position.
