Thank you for buying a Ryobi lawn mower.
Your new lawn mower has been engineered and
manufacturer to Ryobi’s high standard for dependability,
ease of operation, and operator safety. Properly cared for,
it will give you years of rugged, trouble-free performance.
WARNING
Do not attempt to operate this mower until you have
read thoroughly and understood completely all
instructions, safety rules, etc. contained in this manual.
Failure to comply may result in accidents involving re
or serious personal injury. Save operator’s manual and
review frequently for continuing safe operation and
instructing others who may use this tool.
GENERAL SAFETY RULES
PERSONAL SAFETY
■This lawn mower is capable of amputating hands and
feet, and throwing objects. Failure to observe all safety
instructions could result in serious injury or death.
■Never allow children or people with reduced physical,
sensory, mental capabilities or unfamiliar with the
instructions to use the mower. Local regulations may
restrict the age of the operator. Children should be
adequately supervised to ensure they don’t play with
the mower.
■Ensure before each use that all controls and safety
devices function correctly. Do not use the tool if the
“off” switch does not stop the engine.
■Stay alert, watch what you are doing, and use common
sense when operating the lawn mower. Do not operate
the mower while tired or under the influence of drugs,
alcohol, or medication. A lapse in concentration while
operating the machine may result in serious personal
injury.
■Wear heavy, long trousers, long sleeves, slip-resistant
foot wear, and gloves. Do not wear loose fitting
clothing, short trousers, sandals, or go barefoot.
■Wear ear protection and safety glasses at all times
while operating the machine. Use face mask if
operation is dusty.
■Use of hearing protection reduces the ability to hear
warnings (shouts or alarms). The operator must pay
extra attention to what is going on in the working area.
■Operating similar tools nearby increases both the risk
of hearing injury and the potential for other persons to
enter your working area.
■Always be sure of your footing, especially on slopes.
Keep firm footing and balance. Do not overreach.
Overreaching can result in loss of balance.
■Walk, never run.
■Mow across the face of slopes, never up and down.
Exercise extreme caution when changing direction on
slopes.
■Do not mow near drop-offs, ditches, excessively steep
slopes, or embankments. Poor footing could cause a
slip and fall accident.
■Plan your mowing pattern to avoid discharge of
material toward roads, public pavements, bystanders
and the like. Also, avoid discharging material against
a wall or obstruction, which may cause the material to
ricochet back toward the operator.
WORK AREA SAFETY
■Keep all bystanders, children, and pets at least 15 m
away from work area. If anyone enters this area, stop
the machine.
■Do not operate in poor lighting. The operator requires
a clear view of the work area to identify potential
hazards.
■Do not operate the machine in explosive atmospheres,
such as in the presence of flammable liquids, gases
or dust. The tool create sparks which may ignite the
dust or fumes.
■Objects struck by the lawn mower blade can cause
severe injuries to persons. Thoroughly inspect the
area where the machine is to be used and remove all
rocks, sticks, metal, wire, bones, toys, or other foreign
objects.
■Do not operate the machine in wet grass or in the rain.
■Keep in mind that the operator or user is responsible
for accidents or hazards occurring to other people or
their property.
■Tragic accidents can occur if the operator is not alert to
the presence of children. Children are often attracted
to the machine and the mowing activity. Never assume
that children will remain where you last saw them.
■Keep children out of the mowing area and under the
watchful care of a responsible adult other than the
operator.
■Use extra care when approaching blind corners,
shrubs, trees, or other objects that may block your
view.
■Keep work area clean. Cluttered or dark areas invite
accidents.
LAWN MOWER SAFETY WARNINGS
■Before using, always visually inspect to ensure blades,
blade bolts, and cutter assembly are not worn or
damaged.
■Replace worn or damaged blades and bolts in sets to
preserve balance.
■Check all nuts, bolts, and screws at frequent intervals
for proper tightness to be sure the equipment is in safe
working condition.

INTENDED USE
This product is intended for domestic lawn mowing. The
cutting blade should rotate approximately parallel to the
ground over which it is being wheeled. All four wheels
should touch the ground while mowing. It is a pedestrian
controlled walk behind mower.
The mower should never be operated with the wheels off
the ground, it should not be pulled or ridden on. It should
not be used to cut anything other than domestic grass
lawns.
RESIDUAL RISK
Even when the product is used as prescribed, it is still
impossible to completely eliminate certain residual risk
factors. The following hazards may arise in use and
the operator should pay special attention to avoid the
following:
■Injury caused by vibration. Always use the right tool for
the job, use designated handles and restrict working
time and exposure.
■Exposure to noise can cause hearing injury. Wear ear
protection and limit exposure.
■Contact with blades
■Injury from thrown objects
RISK REDUCTION
It has been reported that vibrations from hand-held tools
may contribute to a condition called Raynaud’s Syndrome
in certain individuals. Symptoms may include tingling,
numbness and blanching of the ngers, usually apparent
upon exposure to cold. Hereditary factors, exposure to
cold and dampness, diet, smoking and work practices are
all thought to contribute to the development of the these
symptoms. There are measures that can be taken by the
operator to possibly reduce the effects of vibration:
■Keep your body warm in cold weather. When operating
the unit wear gloves to keep the hands and wrists
warm. It is reported that cold weather is a major factor
contributing to Raynaud’s Syndrome.
■After each period of operation, exercise to increase
blood circulation.
■Take frequent work breaks. Limit the amount of
exposure per day.
If you experience any of the symptoms of this condition,
immediately discontinue use and see your doctor about
these symptoms.
WARNING
Injuries may be caused, or aggravated, by prolonged
use of a tool. When using any tool for prolonged
periods, ensure you take regular breaks.
WARNING
To avoid serious personal injury, do not attempt

■Feed bolt through hole A for a higher handle height
(on both sides)
■Feed bolt through hole B for a lower handle height (on
both sides)
■Secure in place by tightening the lock nuts onto the
end of the bolts (both sides).
■The collapsible handle grey lock knob and
corresponding bolt need not be touched for handle
height adjustment.
MOWING TIPS
■Make sure the lawn is clear of stones, sticks, wires, and
other objects that could damage the mower blades or
engine. Such objects could be accidentally thrown by
the mower in any direction and cause serious personal
injury to the operator and others.
■For best performance, always cut off one-third or less
of the total height of the grass.
■When cutting long grass, reduce walking speed to
allow for more effective cutting and a proper discharge
of the clippings.
■Do not cut wet grass. It will stick to the underside of
the deck and prevent proper catching of the grass
clippings.
■New or thick grass may require a narrower cut path.
■Clean the underside of the mower deck after each use
to remove grass clippings, leaves, dirt, and any other
accumulated debris.
SLOPE OPERATION
See gure 10.
■Slopes are a major factor related to slip and fall
accidents that can result in severe injury. Operation on
slopes requires extra caution. If you feel uneasy on a
slope, do not mow it. For your safety, do not attempt to
mow slopes greater than 15 degrees.
■Mow across the face of slopes, not up and down.
Exercise extreme caution when changing direction on
slopes.
■Watch for holes, ruts, rocks, hidden objects, or bumps
which can cause you to slip or trip. Tall grass can hide
obstacles. Remove all objects such as rocks, tree
limbs, etc., which could be tripped over or thrown by
the blade.
■Always be sure of your footing. A slip and fall can cause
serious personal injury.
■Do not mow near drop-offs, ditches, or embankments;
you could lose your footing or balance.
EMPTYING THE GRASS CATCHER

FUEL CAP
WARNING
A leaking fuel cap is a re hazard and must be replaced
immediately.
The fuel cap contains a non-serviceable lter and a
check valve. A clogged fuel cap will cause poor engine
performance. If performance improves when the fuel
cap is loosened, check valve may be faulty or clogged.
Replace the fuel cap if required.
CHANGING ENGINE OIL
See gure 15.
Engine oil should be changed after every 25 hours of use.
Change the oil while the engine oil is still warm, but not
hot. This allows the oil to drain quickly and completely.
NOTE: Ensure the fuel tank is completely empty before
tipping the unit over otherwise fuel will leak out.
■Remove the oil fill cap/dipstick.
■Tip mower onto its side and allow oil to drain from the
oil fill hole into an approved container.
■Place mower upright and refill with oil following the
instructions in the Adding/Checking Oil section.
NOTE: Used oil should be disposed of at an approved
disposal site. See your local oil retailer for more
information.

SPARK PLUG MAINTENANCE
See gure 13.
The spark plug must be properly gapped and free of
deposits in order to ensure proper engine operation. To
check:
■Remove the spark plug boot.
■Clean any dirt from around base of spark plug.
■Remove spark plug using a spark plug socket (not
provided).
■Inspect spark plug for damage, and clean with a wire
brush before reinstalling. If insulator is cracked or
chipped, spark plug should be replaced.
NOTE: The recommended spark plug models is NGK
BPR6HS. Spark plug can be ordered through the
Bunnings Special orders desk – 30010Z0201200.
(Ryobi part number for Australia and New Zealand).
■ Measure plug gap. The correct gap is 0.028 − 0.031 in.
To widen gap, if necessary, carefully bend the ground
(top) electrode. To lessen gap, gently tap ground
electrode on a hard surface.
■Seat spark plug in position; thread in by hand to
prevent cross-threading.
■Tighten with wrench to compress washer. If spark plug
is new, use 1/2 turn to compress washer appropriate
amount. If reusing old spark plug, use 1/8 to 1/4 turn
for proper washer compression.
NOTE: An improperly tightened spark plug will become
very hot and could damage the engine.
■Reinstall spark plug boot.
STORING THE MOWER
When storing the mower for 30 days or more:
■If using fuel stabilizer, follow stabilizer manufacturer’s
directions to add stabilizer to petrol in fuel tank. Run
engine at least 10 minutes after adding stabilizer to
allow the stabilizer to reach the carburettor.
WARNING
Do not store the lawn mower with petrol in the tank
inside a building where fumes may reach an open ame
or spark.
■If not using fuel stabilizer, allow the engine to run until
the mower is completely out of petrol.
■Once the engine has stopped, allow the blade to come
to a complete stop and disconnect the spark plug wire.
■Turn the fuel tap to the closed position.
■Check all nuts, bolts, knobs, screws, fasteners, etc.,
for tightness.
■Inspect moving parts for damage, breakage, and wear.
Have repairs made on any damaged or missing parts.
■Store the mower in a well-ventilated area that is clean,
dry, and out of the reach of children.

rope from guide and allow to retract into engine.
■Fully loosen the handle knobs on the sides of the
handle and fold the upper handle down.
■Remove the handle knobs and bolts from each side of
the lower handle at the handle bracket, (mounted on
the mower deck).
■Push inward on each side of the lower handle, and
lift the sides of the lower handle past the edges of the
handle mounting brackets.
■Fold the lower handle forward, making sure not to
bend or kink the control cables.

TROUBLESHOOTING
PROBLEM POSSIBLE CAUSE SOLUTION
Handle not in cor-
rect position.
Handle positioned incorrectly. Check to be sure that lower part of handle is pushed fully back
and snapped into proper position.
Handle knobs not tightened. Tighten handle knobs.
Mower not
starting.
No petrol. Fill the mower with petrol. Turn the fuel tap to the open position.
If the mower still does not start contact a servicing dealer.
Engine is ooded. Wait 15 minutes, then try starting mower again. Do not prime
before attempting to start. Refer to STARTING / STOPPING THE
MOWER section but exclude the priming steps.
Old fuel. Only use fresh fuel. Fuel over 30 days old may prevent the unit
from starting.
No spark. Check spark. Remove spark plug. Reattach the spark plug cap
and lay spark plug on metal cylinder. Pull the starter rope and
watch for spark at spark plug tip. If there is no spark, repeat test
with a new spark plug.
Engine cutting out
after 5 minutes
Fuel tap most likely in the
CLOSED position therefore
only 5 mins of fuel left in the
fuel bowl.
Check Red fuel tap position.
= OPEN Fuel line for operation
= CLOSED Fuel line closed for when not in use (storage).
Mower hard to
push.
High grass, rear of mower
housing and blade dragging in
heavy grass, or cutting height
too low.
Raise cutting height.
Mower vibrating at
higher speed.
Blade is unbalanced.
Bent motor shaft.
Replace blade.
Stop the engine, disconnect the spark plug wire from the spark
plug, and inspect for damage. Have repaired by an authorized
service center before restarting.
Mower not mulch-
ing properly
Wet grass clippings sticking to
the underside of the deck.
Wait until the grass dries before mowing.
Mower not
catching properly
Cutting height set too low. Raise cutting height. Cutting very wet grass at a low cutting height
will also greatly hinder the ability of the mower to throw the grass
to the catcher. Suggest raising the cutting height or cutting the
grass when it is not as wet.
