2.3 HOW TO USE THE PARTS MANUAL
ITEMNUMBER
Each part which is identified in the illustrations has an item number. Parts which do not have an item number
may not be readily identified in the illustration but are usually closely associated with the immediately adjacent
part.
ASSEMBLIES
A complete assembly, e.g. a wheel motor or hydraulic motor or roll assembly, is listed as a complete item with
subsequent individual components listed separately.
The assembly is listed under it's part number with component parts being listed offset to the right, e.g:-

MAINTENANCE AND PARTS MANUAL
3 SAFETY 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.
3.1 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 usethis
machine. Local regulations may restrict
the age of the operator.
3.2 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.
3.3 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.
3.4 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.
3.5 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.
• Sudden decelerating or braking can
cause the rear wheels to lift.
• Remember that the stability of the rear
of the machine is reduced as the fuel is
used.

GB-5
JACOBSEN 405 Series: CH
MAINTENANCE AND PARTS MANUAL
3 SAFETY INSTRUCTIONS
3.6 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.
3.7 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.
• Sudden decelerating or braking can
cause the rear wheels to lift. Remember
there is no such thing as a “safe” slope.
• Travel on grass slopes requires particular
care.
DO NOT USE ON SLOPES GREATER THAN 15°
IMPORTANT: When working on any slope set the
weight transfer, if fitted to its maximum (+) setting.
3.8 BLOCKED CUTTING CYLINDERS
• 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.
3.9 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.
• Do not alter engine speed above maximum
quoted in Engine Specification. Do not
change the engine governor settings or
overspeed the engine. Operating the engine
at excessive speed may increase the hazard
of personal injury.
• When refuelling, STOP THE ENGINE, DO
NOT SMOKE. Add fuel before starting the
engine, never add fuel while the engine is
running.
• Use a funnel when pouring fuel from a can
into the tank.
• Do not fill the fuel tank beyond the bottom of
the filler neck.
• Replace all fuel tank and container caps
securely.
• Store fuel in containers specifically designed
for this purpose.
• Refuel outdoors only and do not smoke while
refuelling.
• If fuel is spilled, do not attempt to start the
engine but move the machine away from the
area of spillage and avoid creating any
source of ignition until fuel vapours have
dissipated.
• Allow the engine to cool before storing in any
enclosure.
• Never store the equipment with fuel in the
tank inside a building where fumes may
reach an open flame or spark.
• If the fuel tank has to be drained, this should
be done outdoors.
• Do not spill fuel onto hot components.
• When servicing batteries, DO NOT SMOKE,
and keep naked lights away.
• Do not place any metal objects across the
terminals.

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

WARNING
Before releasing transport latches it is
important that all cutting units are fully raised.
1. Park the machine on level ground.
2. With the engine running at operating
speed raise the cutting units to their

levers whilst seated in the driving
position.
3. Disengage drives, stop the engine and
make sure all moving parts are
stationary. Apply brakes and remove
the starter key.
