Safety Instructions
Transporting the mower
• Turn the engine off, by moving the throttle lever to the 'STOP' position and switching the
fuel tap off (where fitted).
• Disconnect the spark plug lead and wedge it between the cylinder head fins.
• Do not transport the mower in a vehicle if there is fuel in the fuel tank.
Before using the mower
• Do not start the mower until you have studied the instruction manuals.
• Know the mower controls. Learn how to stop the engine quickly in an emergency by
moving the throttle to the 'STOP' position.
• Before using the mower, ensure that the blade assembly is not worn or damaged.
Always replace worn or damaged blades and bolts in sets to preserve correct balance.
Damaged or worn blades and bolts are major hazards. Use genuine Bushranger spare
parts only.
• Please note blades are tucked under blade disc for safety and transport reasons
before use. Once the engine is started they will relocate themselves for cutting.
• Check all fasteners regularly. Always ensure the mower is in a safe operating condition.
• Check for grass build up around the engine and muffler which may cause overheating
and/or a fire hazard.
• Do not start the engine unless the side chute and bumper bars are securely in position.
Operating the mower
• Do not mow while people or pets are in the vicinity of the mower or within the mowing
area. Ensure that bystanders are a minimum of 15 metres away.
• Do not mow in bare feet or open shoes. Wear long trousers and heavy footwear.
• Make sure the lawn is clear of sticks, stones, bones, wire and debris before mowing.
These could be thrown by the blades and cause injury or damage.
• Start the engine carefully with feet well clear of blades. Do not tilt the mower when
starting the engine.
• Stop the engine whenever you leave the mower, even for a moment.
• Mow only in good daylight.
• Keep hands and feet away from rotating parts beneath mower when engine is running.
• Do not over speed the engine or alter the governor settings. Excessive engine speed is
dangerous and shortens mower life.

2
Safety Instructions (cont.)
• Never lift, carry or tilt the mower when the engine is running.
• Stop the engine before pushing the mower across gravel, paths or roads. Stop the
engine before the mower leaves the lawn.
• Stop the engine before adjusting the cutting height.
• Mow across the face of a slope, never up or down. Use extreme caution when changing
direction on a slope. Do not mow on excessively steep slopes.
• Never mow by pulling the mower towards you. You may slip and pull the mower on top
of your feet.
• Walk with the mower, never run.
• The safety distance determined by the guiding handles must be maintained at all times.
• At the conclusion of mowing, always turn the mower off using the throttle lever then turn
fuel tap off (where fitted).
Maintaining the mower
• If the mower begins to vibrate abnormally, or if it strikes a foreign object - STOP the
engine, disconnect the spark plug lead from the spark plug and carefully wedge it
between the cylinder fins. Inspect the mower and blades for any damage.
• Replace worn or faulty mufflers as they adversely affect engine performance and increase
emissions.
• Bushranger recommends that all maintenance, repair and inspection work be carried out
by a Bushranger Authorised Service Centre.
• Store the mower in a well ventilated area, away from any naked flames such as those
found in hot water heaters.
Refuelling the mower
• Refuel the mower outdoors only.
• Do not smoke when refuelling the engine. Never add fuel or remove the fuel cap while
the engine is running or hot. If fuel is spilt, do not start the engine. Move the mower
away from the area of the spill. Do not create any source of ignition until fuel vapours
have dissipated.
• Store fuel in a cool place and in a container specifically designed for the purpose. Plastic
containers are unsuitable, except those specifically designed to hold fuel.

3
Hazards
The following safety precautions must be strictly observed to avoid the risk of damage or
personal injury.
• Do not smoke while operating or refuelling the mower. Never add fuel or remove the fuel cap
while the engine is running or hot. If the fuel is spilt, do not start the engine. Move the mower
away from the area of the spill. Do not create any source of ignition until the fuel vapours have
dissipated.
• Check all fasteners regularly. Always ensure that the mower is in safe operating condition.
Use genuine spare parts only.
• Do not operate the mower in confined spaces where exhaust fumes (carbon monoxide) can
collect.
• Stop the engine whenever you leave the mower, even if only for a moment.
• Stop the engine when emptying the grasscatcher. Never try to clear grass from inside the
mower while the engine is running.
• Never lift, carry or tilt the mower when the engine is running.

Cleaning
Before cleaning the mower, ensure
the throttle lever is in the 'STOP'
position. Turn the fuel tap off,
disconnect the spark plug lead and
wedge it between the cylinder fins.
• Remove grass build up from the air intakes on the top of the mower cowl, around the
engine and carburettor, and around the air filter body.
• The underside of the mower should be cleaned regularly to remove dirt and grass build
up, any build up will adversely affect corrosion of steel baseplate.
Spark
Plug

• When cleaning the underside of the mower, always tilt handle back to ground level
so the front wheels are off the ground and spark plug is pointing to the sky (4 stroke
engined mowers).
• Tilting in other directions can cause the oil to contaminate the fuel & damage airfilter
causing starting difficulties (4 stroke models).
• To prevent chassis corrosion, the underside of your mower should be cleaned
immediately after mowing an area which has been recently dressed with sulphate
of ammonia or fertiliser.
• After cleaning, run the engine briefly to dry off excess moisture before storing.
Cleaning
7
• Stop the engine and disconnect the spark plug lead before fitting new blades.
Assembly: Fit as per the drawing remembering to push the head of the bolt into the
blade disc. (this will stop the bolt head from turning). Ensure correct order of assembly.
DO NOT lay mower on side 4 stroke models.
• We recommend changing blades, bolts, nuts and washers as a set. Metal fatigue and
damage may occur which may not be visible to the operator. Always replace all blades
to ensure correct engine balance, reducing vibration and wear. Tighten nuts on blade
bolts to 14-19 Nm (Newton Metres) or 10-14 ft lbs.
• Always turn the nut to check tightness, not the bolt.
Use only genuine replacement parts made and guaranteed by Bushranger. Insist
on
them from your parts and service dealer.
NOTE: Use of non-genuine blades may void your warranty,and could result in
damage or injury.

For Your Safety
• Never use the mower unless the side chute and bumper bars supplied by the
manufacturer are in position.
• Before starting the mower check blades and bolts for damage or wear.
• If you strike an obstruction, stop the engine, disconnect spark plug lead from the spark
plug and check the blades for damage.
Worn and damaged blades are major hazards.

For correct engine performance and to guard against dust entering the engine, causing
rapid wear, the air filter assembly must be clean and maintained in good condition.
Bushranger recommends that the air filter element and seal ring are replaced annually,
or more often in dusty conditions. Always replace with genuine Bushranger spare parts.
Use of non-genuine spare parts may damage your mower engine, and void the product
warranty.
