This safety symbol indicates important safety
messages in this manual. When you see this
symbol, be alert to the possibility of injury,
carefully read the message that follows, and
inform other operators.
2.1 OPERATING INSTRUCTIONS
• Ensure that the instructions in this book
are read and fully understood.
• No person should be allowed to operate
this machine unless they are fully
acquainted with all the controls and the
safety procedures.
• Never allow children or people unfamiliar
with these instructions to use this
machine. Local regulations may restrict
the age of the operator.
2.2 SAFETY SIGNS
• It is essential all safety labels are kept
legible, if they are missing or illegible
they must be replaced. If any part of the
machine is replaced and it originally
carried a safety label, a new label must
be affixed to the replacement part. New
safety labels are obtainable from
Ransomes dealers.
2.3 STARTING THE ENGINE
• Before starting the engine check that the
brakes are applied, drives are in neutral,
guards are in position and intact, and
bystanders are clear of the machine.
• Do not run the engine in a building
without adequate ventilation.
2.4 DRIVING THE MACHINE
• Before moving the machine, check to
ensure that all parts are in good working
order, paying particular attention to
brakes, tyres, steering and the security
of cutting blades.
• Replace faulty silencers, mow only in
daylight or good artificial light
• Always observe the Highway Code both
on and off the roads. Keep alert and
aware at all times. Watch out for traffic
when crossing or near roadways.
• Stop the blades rotating before crossing
surfaces other than grass.
• Remember that some people are deaf or
blind and that children and animals can
be unpredictable.
• Keep travelling speeds low enough for an
emergency stop to be effective and safe
at all times, in any conditions.
• Remove or avoid obstructions in the area to
be cut, thus reducing the possibility of injury
to yourself and/or bystanders.
• When reversing, take special care to ensure
that the area behind is clear of obstructions
and/or bystanders. DO NOT carry
passengers.
• Keep in mind that the operator or user is
responsible for accidents or hazards
occurring to other people or their property.
• When the machine is to be parked, stored or
left unattended, lower the cutting means
unless the transport locks are being used.
• While mowing, always wear substantial
footwear and long trousers. Do not operate
the equipment when barefoot or wearing open
sandals.
• Check the grass catcher frequently for wear
or deterioration. After striking a foreign
object. Inspect. the lawnmower for damage
and make repairs before restarting and
operating the equipment.
• If the machine starts to vibrate abnormally,
check immediately.
2.5 TRANSPORTING
• Ensure that the cutting units are securely
fastened in the transport position. Do not
transport with cutting mechanism rotating.
• Drive the machine with due consideration of
road and surface conditions, inclines and
local undulations.
2.6 LEAVING THE DRIVING POSITION
• Park the machine on level ground.
• Before leaving the driving position, stop the
engine and make sure all moving parts are
stationary. Apply brakes and disengage all
drives. Remove the starter key.
2.7 SLOPES
TAKE EXTRA CARE WHEN WORKING ON SLOPES
• Local undulations and sinkage will change
the general slope. Avoid ground conditions
which can cause the machine to slide.
• Keep machine speeds low on slopes and
during tight turns.
• Remember there is no such thing as a “safe”
slope.
• Travel on grass slopes requires particular
care.

MANUAL
GB
2.8 BLOCKED CUTTING DEVICE
• Stop the engine and make sure all moving
parts are stationary.
• Apply brakes and disengage all drives.
• Release blockages with care. Keep all parts of
the body away from the cutting edge. Beware
of energy in the drive which can cause rotation
when the blockage is released.
• Keep other people away from the cutting units
as rotation of one cylinder can cause the
others to rotate.
2.9 ADJUSTMENTS, LUBRICATION AND
MAINTENANCE
• Stop the engine and make sure all moving
parts are stationary.
• Apply brakes and disengage all drives.
• Read all the appropriate servicing instructions.
• Use only the replacement parts supplied by
the original manufacturer.
• When adjusting the cutting cylinders take care
not to get hands and feet trapped when rotating
cylinders.
• Make sure that other people are not touching
any cutting units, as rotation of one cylinder
can cause the others to rotate.
• To reduce the fire hazard, keep the engine,
silencer and battery compartments free of
grass, leaves or excessive grease.
• Replace worn or damaged parts for safety.
• When working underneath lifted parts or
machines, make sure adequate support Is
provided.
• Do not dismantle the machine without
releasing or restraining forces which can cause
parts to move suddenly.
DANGER - Indicates an imminently hazardous
situation which, if not avoided, WILL result in death
or serious injury.
WARNING - Indicates a potentially hazardous
situation which, if not avoided, COULD result in death
or serious injury.
CAUTION - Indicates a potentially hazardous
situation which, if not avoided, MAY result in minor or
moderate injury and property damage. It may also be
used to alert against unsafe practices.
Hydraulic Fluid escaping under
pressure can penetrate skin and do
serious damage. Immediate medical
assistance must be sought.
