SAFETY INSTRUCTIONS
Read, understand, & follow all instructions in the Owner/
Operators manual.
Know the controls and how to stop the engine quickly in
an emergency.
Allow only responsible adults, who are familiar with the
instructions in this manual, to operate the machine.
Clear the area to be mowed of loose objects such as
sticks, stones, bones, wire, toys, debris, etc., which
could be picked up and thrown by the blades.
DO NOT mow whilst people, especially children, or pets
are in the mowing area.
DO NOT mow either direction on slopes beyond 15
degrees, (1 in 3.75).
Exercise extreme caution on slopes.
Reduce speed on slopes and in sharp turns to prevent
overturning or loss of control.
Start or stop slowly when on slopes.
Mow up and down slopes, not across the slope.
Stay alert for holes or bumps in the terrain and other
hidden hazards.
Use care when pulling loads-
a] Use only approved hitch point;
b] limit loads to those you can safely control;
c] Do not turn sharply;
d] use care when backing up.
Watch out for traffic when crossing or operating the
mower near roadways.
Stop the blades rotating before crossing surfaces other
than grass.
When using attachments, never direct discharge of
material toward bystanders nor allow anyone near the
machine while it is in operation.
Before leaving the operators position-
a] Disengage all clutches and secure cutting units;
b] Return drive pedal to neutral position and set the
parking brake;
c] Stop the engine and remove the key.
Disengage drive to attachments and stop engine-
a] Before refueling.
b] Before removing grass-catcher;
c] Before clearing blockages from chute;
d] Before checking, cleaning or working on the mower;
e] After striking a foreign object (check the mower for
damage and make repairs before restarting and
operating the equipment);
f] If machine starts to vibrate abnormally (check
immediately).
Disengage drive to attachments when transporting or
not in use.
A mower operator should be in good physical and
mental health and not under the influence of alcohol or
any drug which might impair vision, co-ordination or
judgment.
Never mow while barefoot or wearing open sandals or
thongs. Wear long trousers and heavy shoes.
It is advisable to wear suitable eye protection when
operating a mower.
Mow only in daylight or good artificial light.
Before using, always visually inspect to see that blades,
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 often; always be sure
the mower is in safe operating condition.
Keep safety devices (guards and switches) in place and
in working order.
Never use the mower unless the grass catcher, or
guards provided by the manufacturer, are in position.
Ensure any replacement parts used comply with the
original manufac tu re’s re commendations and
specifications.
Replace worn or faulty silencers.
Keep machine free of grass, leaves or other debris,
excessive oil, grease, or spilt fuel. These can be a fire
hazard.
Refuel outdoors only. Do not smoke while fueling
engine. Never remove the cap of the fuel tank or add
petrol while the engine is running or the engine is hot.
Remove fuel cap slowly to relieve any tank pressure. If
fuel is spilled, do not attempt to start the engine but
move machine away from the area of the spill and avoid
creating any source of ignition until fuel vapors have
dissipated.
Check for fuel leaks while refueling, before and while
using the mower. If a fuel leak is found, do not start or
run the engine until the fuel leak is fixed and spilled fuel
is wiped away.
Do not operate engine in a confined space where
exhaust fumes (carbon monoxide) can collect.
Always mount the mower from the left or the opposite
side to the discharge chute.
Start the engine carefully with the cutting means
disengaged.
Do not over-speed the engine or alter governor settings.
Excessive speed is dangerous and shortens mower life.
Stop the engine whenever you leave the mower, even
for a moment.
Store the mower in a well-ventilated room away from
naked flames such as may be found in hot water
heaters.
Do not lend or sell the mower, without the owners/
operators Manual.

attachment clutch/brake control
(manual or electrical) is in the
off O position, place right foot
on and depress start foot
switch , insert key in ignition
switch, turn key all the way
right to start (3rd) position,
release key when engine has
started. Note: Continuous
(Continued on page 8)
OPERATING INSTRUCTIONS
Rev 3 18/07/2014 Page 8 Model Number A12612A
cranking for more than 15
seconds can damage the starter
motor. Short starting cycles
give best starter motor life.
Allow starter motor to cool for 2
minutes before attempting to
restart engine. After engine
starts, move throttle control out
of the choke position and into
the orange range, move throttle
control lever to obtain desired
engine speed.
Hot engine:
To start engine, place throttle
control slightly past slow
position, ensure mowing
attachment clutch/brake control
(manual or electrical) is in the
off O position, place right foot
on and depress foot switch
plate, insert key in ignition
switch, turn key all the way
right to start (3rd) position,
release key when engine has
started. Move throttle control lever
to obtain desired engine speed.
STOPPING ENGINE
When stopping engine, ensure
mowing attachment clutch/
brake control (manual or
electrical) is in the off position,
return throttle to slow position,
turn ignition switch to the off O
(1st) position.
DRIVING - TO TRAVEL
MACHINE FORWARD OR
REVERSE:
With engine running set
throttle control lever to obtain
desired engine speed. Apply
downward pressure on front
of drive pedal with toes to
travel forward, or apply
downward pressure on back of
drive pedal with heel to travel
in reverse. It is not necessary
to apply foot brake before
changing from forward to
reverse or reverse to forward.
The amount of pressure can
be used to control the ground
speed, light pressure will give
a slow ground speed, heavy
pressure will give a fast
ground speed. Heavy pressure
may also be required when
travelling up slopes or when
heavy loads are being towed
or carried. Excessive pressure
should not need to be applied
to the drive pedal to obtain a
fast ground speed. When
operating the mower on
slopes greater than 10
degrees but less than 15
degrees for a prolonged
period, you may experience
minor clutch fade, should this
occur, vary your mowing style
eg: mow around some flat
areas, then the slope followed
by the flat area again. This
will allow the drive to cool
before travelling up the slope
again.
NOTE:
When mowing slopes
keep clutch pedal in
forward or reverse,
depending on the
direction of the machine.
The low gearing will
prevent it from picking
up excessive speed. If
very steep, it may be
necessary to throttle
back slightly and or
apply a light pedal
pressure to the opposite
clutch plate. i.e. move
clutch pedal into reverse
when going forward
down a slope or into
forward when reversing
down a slope. Ensure
that when pressure is
applied to the drive pedal
the back wheel/s start
rotating or damage will
occur to drive system.
NOTE– Do Not mow
either direction on slopes
beyond 15 degrees (1 in
3.75).
TO STOP MACHINE
TRAVEL
ENGINE RUNNING:
The drive pedal may be used to
stop the machine. If traveling
forward push the pedal into
reverse until machine stops,
then bring the pedal back to
neutral position or vice versa if
traveling in reverse. Should
failure of the drive system occur
during operation use the foot
brake pedal to stop machine
travel.
ENGINE STOPPED:
Use foot brake pedal only.
NOTE:
Damage to clutch cone
will occur if clutch pedal
is used to stop machine
travel with the engine
not running.
MANOEUVRING:
Due to the heel and toe type
action of the drive pedal, it is
possible to take the machine
straight from forward to reverse
and vice versa without applying
the foot brake. This instant
forward and reverse operation
in conjunction with it tight
turning radius makes the
machine very maneuverable
and the sharpest turns can be
negotiated easily and quickly.
Note:
T a k e c ar e w h e n
reversing, always look in
the direction of intended
travel before changing
direction.
DIFFERENTIAL OPTION:
The differential is used to
permit the back wheels to
rotate at different speeds when
mane uvering tight turns
avoiding wheel slip which may
damage the lawn.
TRANSPORTING
If your machine is transported
regularly from site to site,
especially by trailer, it is
recommended to either adjust
clutch plates wide apart (retigh ten bolts) or place
cardboard between clutch cone
and clutch plates to avoid
damaging the clutch cone.

BATTERY MAINTENANCE-
When not in use, a battery discharges by
as much as 1% a day, more when the
climate is warm. To make up for this
loss, a boosting charge should be given
once a month. Disconnect battery
terminals to charge, then allow to stand
minimum 1/2hr before re-connecting. If
a battery is not used for a period of more
than three (3) months, the terminals
should be disconnected and trickle
charged at two (2) amps for two (2)
hours once every three (3) months or
before use.
GREASE STUB AXLES -
Clean grease nipple, use grease gun and
general purpose grease to force old grease
from top and bottom of front axle bushes.
Jack up front of machine if grease is not
released from bottom of bush.
