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.

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.

6.2 MOW/TRANSPORT SPEED CONTROL
When cutting heads are raised completely, the
wheel drive speed range is 0 7.5 mph (0 12 Km/
hr). Speed is controlled by use of the direction/
speed control pedal as described in control pedals
section.
When cutting heads are lowered, the forward
movement of the direction/speed control pedal is
restricted by the automatic mow speed control
linkage (the bellcrank stop screw contacts the foot
pedal tab which rotates the pedal upward. This in
turn reduces the ground speed of the unit for
mowing). The mow speed range is 0 3.8 mph (0
6.1 Km/hr).
ADJUSTING MOW SPEED
To determine mow speed, run a time check on how
fast the unit travels in a distance of 50 (15.24 M).
Prepare a level surface with enough room to start
and end beyond the 50 marks.
Place a stake in the ground where you want to begin
timing the unit. Measure and place another stake at
a distance of 50 (15.24 M). Lower the cutting heads
and press the direction pedal forward so the unit is
traveling at full throttle (the cutting heads should be
in the neutral position when timing the unit).
Begin timing the unit when the center of the front tire
aligns with the first stake. Stop timing when the
center of the front tire aligns with the stake placed at
50 (15.24 M). Estimated time for 3.8 mph (6.1 Km/
hr) will be approximately 8.8 to 9.2 seconds. If there
is a significant difference in the times listed above,
you can adjust the mow speed as follows.

increase mow speed.
Determine which direction to adjust the mow speed
screw. Loosen the locking nut and adjust speed
control screw, snug up the locking nut and run the
time test again, repeat as necessary. When correct
mow speed has been obtained, tighten the locking
nut (See Fig. 6.3.1).
TO SET BELLCRANK STOP SCREW:
NOTICE
The bellcrank stop screw has been set at the factory

6.5 BACKLAPPING
Backlapping on a regular basis will help keep the
cutting edges sharp and extend the life of the reel.
Backlapping may be performed on one cutting head
only, two heads, or all three heads simultaneously. If
backlapping one or two cutting heads is desired,
back off slightly on the bedknifetoreel clearance on
the head(s) not requiring backlapping. This will
eliminate contact between bedknife and reel,
avoiding the possibility of damaging the reel or
bedknife during the backlap process. Always make
bedknife adjustments with the Engine Off.
NOTICE
Make sure the bedknife adjustment is
correct before backlapping. Refer to
Bedknife Adjustment .
2. Slowly turn the restriction valve knob
clockwise until the desired reel rotation
speed is attained. It should be slow
enough so that the reel will not throw off
the backlapping compound as it spins.
3. Apply an even coat of backlapping
compound to the entire length of each
blade of the reel. Use a brush with a long
enough handle to keep you away from the
rotating blades. For best results, use a
handle length which will permit application
of compound while standing in front of the
unit.
4. Once all the blades on the reel are
uniformly sharp, shut off the engine and
switch the reel enable switch to the off
position. Set the reel valve control to the
mow position and close the restriction
valve (all the way clockwise).
NOTICE
To ensure proper reel rotation, make sure
the restriction valve is completely closed.
5. Wash all of the backlapping compound
from all of the heads. Once they are
thoroughly cleaned and dry, apply a light
film of oil to the cutting edges to help
prevent rust.
6. After backlapping, the bedknife adjustment
should be made again.

circuit. This will cause the reels
to start turning IMMEDIATELY at
full speed.
Keep hands, feet and clothing
away from all three reels
whenever the reel control lever
is placed in the backlap position.
When backlap restriction valve is
closed or being closed, all three
reels will rotate in the backlap
direction.
WARNING
1. Open the restriction valve on the reel valve
by turning the knob counterclockwise as
far as it will go (See Fig. 6.6.1).
2. Set the reel control lever to the right for the
backlap position (See Fig. 6.6.1).
