FITTING INSTRUCTIONS
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
2 SAFETY INSTRUCTIONS
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.
2.8 BLOCKED CUTTING CYLINDERS
• Stop the engine and make sure all moving
parts are stationary.
• Apply brakes and disengage all drives.
GB-5
JACOBSEN FAIRWAY CUTTING UNITS
REAR ROLLER BRUSH KIT
FITTING INSTRUCTIONS
• 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.
