MOWER
BEFORE STARTING THE
Prevent Engine Damage
To prevent engine damage the engine is shipped without oil or
petrol. The engine must be filled with the correct grade of oil and
petrol before starting the engine.
Oil Type
Always use high quality detergent oil classified “For service SE, SF,
SG” SAE 30 oil. Never use additives with recommended oils.
SAE 10W-30 multigrade oil may be used, but this will result in higher
engine operating temperatures with consequential high oil consump-
tion. It is imperative that the oil level is checked more frequently if this
grade of oil is used in order to guard against serious engine damage.
To prolong the life of your engine it is important that the oil is changed
after the first 5 hours of use - refer to ‘Maintenance Schedule’.
Check Oil Level
0.15
Clean around the oil filler cap before removing. With the mower on a
level surface, unscrew and remove the oil filler - dipstick. Wipe oil
Litres
from it with a clean cloth. Screw the oil filler - dipstick back in place,
then unscrew and remove it to check the oil level.
The oil level is correct when it is at the full mark on the dipstick.
15C
DO NOT OVERFILL.
Fuel Type
Always use clean, fresh unleaded petrol. Purchase fuel in quantities
that can be used within 30 days. Never mix oil with petrol. For added
engine protection Briggs & Stratton recommend the use of their fuel
additive which is available from an authorised Briggs & Stratton ser-
vice dealer.
Fill to base of neck to allow for fuel expansion. Do not overfill the
fuel tank.

OPERATING THE MOWER
Controls
Operate all control levers several times and ensure that the cables
move freely. Check that the engine stop and ground drive clutch levers
return freely to their rest position when released.
Whilst operating the engine throttle mechanism slight resistance
should be felt when moving the lever to the ‘choke’ position.
Starting - Step 1
Move the throttle control lever to the ‘choke’ position before starting
a cold engine. Move the throttle control lever to the ‘fast’ position
before starting a warm engine.
Step 2
Using your left hand turn the ignition key clockwise and hold in posi-
tion to crank the engine. When the engine sarts release the key and set
the throttle to the fast position if initially in the choke position.
The engine stop lever must be held firmly against the handlebar to
start and keep the engine running. If the engine stop lever is
released the engine will stop.
CS075
IMPORTANT: PREVENT ENGINE DAMAGE: Do not use the
ignition key when the engine is running.
Note: If necessary the engine can be started manually with the use of
the engine start grip.
Step 3
Allow the engine to warm up and move the throttle lever to the ‘fast’
position after starting a cold engine.
To prevent damage never pull the engine start grip when the
engine is running.

OPERATING THE MOWER
Forward Travel
Hold the handlebar and operate the ground drive clutch lever to power
the mower in a forward direction.
When the ground drive clutch lever is disengaged the mower may be
pushed. This feature is useful when mowing in confined areas.
If the engine stop lever is released the engine will stop.
Turning
To make a wide turn steer the mower with the handlebar in the direc-
tion required.
To make a tight turn release the ground drive clutch lever, apply down-
ward pressure on the handlebar to raise the front wheels just above
ground level and steer in the required direction.
To prevent accidents do not raise the front of the mower exces-
sively when making a turn. Never raise the rear of the mower
when the engine is running.
Stopping
Release the ground drive clutch lever, reduce the throttle setting and
release the engine stop lever.
Emergency stop: Release both ground drive clutch lever and engine
stop lever together.
If the engine fails to stop, move the throttle lever to the ‘slow’ posi-
tion and disconnect the spark plug lead.
STOP
Slopes
To prevent engine damage do not use the mower on slopes greater
than 20 degrees.

OPERATING THE MOWER
Height of Cut
+
Move the height of cut lever sideways to disengage it from the locking
notch, then push forwards to lower or pull backwards to raise the height
of cut. Release the lever in the required position and ensure that it locks
firmly into one of the seven notch settings.
-
Always select a height of cut to suit operating conditions. Prevent
engine overloading and blockages by avoiding low cuts in long grass
conditions. Be prepared to make two cuts when the grass is long.
305113
Before Mowing
To prevent accidents thoroughly inspect the area and remove all
objects which when contacted by the mower cutterblade could
become dangerous projectiles. Inspect the area for hidden obstruc-
tions which when contacted by the cutterblade could risk health
and safety. Remember the location of these obstructions and
ensure that you mow around them.
Grassbag
Raise the rear deflector and lift the grassbag through the handlebar and
lower the rear deflector to rest against the rear of the mower.
To empty the grassbag, pour out the grass clippings and shake the
grassbag vigorously to clean the airways. Good grass collection
depends on good air flow through the grassbag. When collecting grass
clippings it is important that the grassbag is emptied regularly to pre-
vent blockages and engine overloading.
Without Grass Collection
Remove the grassbag and operate the mower with the rear deflector in
the closed position.
1.14
Download from Www.Somanuals.com. All Manuals Search And Download.
OPERATING THE MOWER
Heavy Growth
Areas of heavy growth should be mown without collecting the clip-
pings. If collection is required, first mow the area without the grass-
bag at the maximum height of cut setting. Allow the grass clippings to
dry out and then mow the area at the maximum height of cut setting
with the grassbag fitted. Reduce the height of cut and mow the area
again as necessary until the required finish is obtained.
305113
To prevent grass damage do not remove more than one third of grass
height in one cut.
Friction Disc
The cutterblade is driven by the engine via a friction disc to help pre-
vent damage occurring to the engine crankshaft and cutting mecha-
nism when a hidden obstruction or overload is encountered.
Always stop the engine when a hidden obstruction or excessive vibra-
tion is encountered. Disconnect the spark plug lead and examine the
cutting mechanism. ALWAYS replace a damaged cutterblade - refer to
“Maintenance”.
Non-Grassed Areas
When moving the mower across non-grassed areas, stop the engine
and set the mower to the maximum height of cut to protect the cutting
mechanism.

LAWN CARE CALENDAR
To be used as a guide only.
January
There is very little work to do this month apart from brushing away
leaves. Keep off the grass if frozen or waterlogged.
February
Rake the grass thoroughly. Spike the lawn to aerate and stimulate soil
organisms and root growth and apply lawn sand if necessary.
March
The yearly lawn work programme really starts this month. As soon as
the ground conditions are suitable, the first cut can be made. The first
cut should merely “top” the grass as close cutting at this stage could
result in severe yellowing or browning. Two cuts are generally suffi-
cient this month.
April
Mow often enough to stop grass growing away. Dig out patches of
coarse grass or resistant weed. Re-seed bare patches.
May
Keep mowing increasing the frequency as required. Treat with selec-
tive weed killers or combined weed/feed preparations if you did not
feed the lawn in April.
June
Summer mowing should now be under way. It should be necessary to
mow the lawn twice a week. Raking before mowing is important this
month as the combined action keeps runners of clover under control.
Water the grass if necessary, and remember to soak thoroughly.
July
Treat the grass with the second application of fertiliser or weed
killer/fertiliser. Water when necessary and rake occasionally. As a gen-
eral rule the grass clippings should be removed each time you mow. If
weather conditions are dry and hot and the grass is weed free, leave the
clippings on the lawn to help maintain ground moisture.
1.16

LAWN CARE CALENDAR
August
Keep mowing regularly and watering as necessary. Fill any cracks
caused by drought with a mixture of sharp sand and soil. In dry weath-
er conditions leave the grass longer to help retain ground moisture.
September
Raise the height of cut to allow the grass to thicken and protect the
roots from the winter frost and snow.
October
Rake out the thatch from the turf and spike the lawn to assist in
drainage. Brush in peat and sharp sand.
November
Use a stiff broom to disperse worm casts before mowing. Keep turf
free from leaves.
December
Apart from brushing away leaves, December is a slack end of a busy
year. Keep off the lawn if it is very wet or frozen.
Lawn Stripes
1
The way to achieve a neat striped effect is for the lawn being cut in
parallel stripes, alternate stripes being mown in opposite directions. A
much more important routine is to cut at right angles to the line of the
previous mowing. If the work has been carried in a north-south line,
then the next cutting should be in an east-west direction. The cross-
cutting keeps down the coarse weed grasses.

1CG480V05A
To prevent grass damage do not remove more than one third of the
grass height in one cut.

To prevent accidents never work on the cutterblade unless the
spark plug lead has been removed. The cutterblade has sharp
edges. ALWAYS wear strong gloves to protect your hands when
working on the cutterblade. DO NOT rotate tools towards the cut-
ting edges to avoid the risk of injury should the tool slip. ALWAYS
use genuine Hayter replacement parts.
The condition of the cutterblade and its mounting arrangement should
be checked regularly for signs of wear or damage. Ensure that the cut-
terblade is not bent or cracked.
A damaged cutterblade that is out of balance will vibrate excessively
and may break. DO NOT use an unbalanced cutterblade.
Regularly check that the bolt securing the cutterblade is tightened to the
specified torque of 54Nm.
Replace the cutterblade every 2 years of sooner if excessively worn or
damaged.
To prevent injury it is wise to seek assistance when turning the mower
on its side.

Cutterblade Assembly

distance piece (3) and tighten to a torque of 54Nm

Cutterblade Sharpening
30°-45°
A slightly worn cutterblade may be re-sharpened. Both blade edges
must be sharpened equally to ensure balance. Sharpen the cutterblade
every 25 mowing hours or more frequently if conditions require.
Remove the cutterblade from the mower and clean using a brush and
water. Inspect the cutterblade for signs of damage.
Sharpen both cutting edges with a flat file to restore performance.
Ensure that the cutterblade is balanced. Use a screw driver with a
round shaft to support the cutterblade through its centre hole. Hold the
cutterblade horizontal and then release. A balanced cutterblade will
remain horizontal.
If the cutterblade is not balanced the heavy end will rotate downwards.
Sharpen the heavy end until the cutterblade is correctly balanced.

MOWER MAINTENANCE
Storage
To store the handlebar unscrew the 2 small securing knobs sufficient-
ly to allow it to be pivoted forwards to rest against the mower. Take
care to ensure that the control cables do not become snagged at the
pivot point and depress the engine stop lever to prevent it being dam-
aged through contact with the engine spark plug.
Engines stored in excess of 30 days need to be protected with Briggs &
Stratton fuel additive or drained of fuel to prevent gum from forming in
the fuel system or on essential carburettor parts. To ensure your mower
is maintained in good working order it is important that the following
procedure is adopted. Refer to the Maintenance section as necessary.
Drain fuel from the engine by operating the engine until it stops.
Disconnect the spark plug lead.
Change the engine oil.
Charge the battery.
Remove the engine spark plug and pour 15ml of engine oil into the
engine cylinder and replace the spark plug. Do not exceed the stated
volume of oil as engine damage may occur on re-starting. Do not
replace the spark plug lead. Slowly pull the engine start - grip once
to crank the engine. This will distribute the oil and help prevent engine
corrosion.
Clean grass and debris from the engine cylinder, cylinder head cooling
fins, under top cowl, and around and behind exhaust/exhaust guard.
Clean all other areas of the mower and ensure that the grassbag is clean.
Lubricate the mower.
Treat metal parts with a water repellent anti-corrosion product.
Disconnect the battery leads.
Cover the mower with a protective sheet and store it in a dry, ventilat-
ed area.

Battery Charging
PREVENT ACCIDENTS: ALWAYS charge the battery in a well
ventilated area.
6hrs
NEVER charge the battery near naked flames or direct heat.
ALWAYS switch off the mains electricity supply before discon-
necting the charger from the battery.
ALWAYS use the battery charger supplied with the mower.
Battery charging should not be necessary during normal use. The
engine operation will automatically charge the battery. If the mower is
stored for a long period recharging the battery may be necessary to
permit electric starting.
Charge the battery only when necessary.
To recharge the battery:
Disconnect the battery lead from the mower lead and then connect the
battery lead to the charger.
Connect the charger plug to the mains electricity supply and switch on
to charge the battery for a six hour period.
Switch off the mains electricity supply and disconnect the charger
plug.
Disconnect the battery lead from the charger and then connect
the battery lead to the mower lead.
IMPORTANT - PREVENT DAMAGE: NEVER connect the bat-
tery charger to the engine lead as this will cause the charger to be
permanently damaged. Chargers damaged in this manner will not
be replaced under warranty.
CAUTION - PREVENT ENVIRONMENTAL DAMAGE: The
battery has a separate collection mark. This indicates that the
used battery must be taken to an authorised disposal site. It must
not be disposed of with general waste.
