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
Litres
Clean around the oil filler cap before removing. With the mower on a
level surface, unscrew and remove the oil filler - dipstick. Wipe oil
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.
DO NOT OVERFILL.
V15C
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 serv-
ice 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 cutterblade 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 start-
posi-
ing a cold engine. Move the throttle control lever to the ‘fast’
tion before starting a warm engine.
Step 2
Stand behind the mower and hold the handlebar with your left hand.
With your right hand hold the engine start - grip and pull slowly until
resistance is felt, then pull rapidly to crank the engine. Carefully return
the start grip to the storage position when the engine starts.
If the engine does not start after 5 attempts - refer to “Trouble
Shooting”.
Note: The cutterblade is not engaged at this stage.
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
Step 4
To engage the cutterblade hold the cutterblade stop lever against the
handlebar with your right hand and with your left hand push the blade
brake clutch lever forwards to engage. Release the blade brake clutch
lever and it will return to its rest position.
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 cutterblade stop lever is released the cutterblade 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 both ground drive clutch lever and the cutterblade stop lever.
Pull the throttle lever to the rear most position.
Emergency stop If the engine fails to stop, disconnect the spark
plug lead.
STOP

OPERATING THE MOWER
Slopes
To prevent engine damage do not use the mower on slopes greater
than 20 degrees.
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 cutterblade could become
dangerous projectiles. Inspect the area for hidden obstructions
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.
1.16
Download from Www.Somanuals.com. All Manuals Search And Download.
OPERATING THE MOWER
Without Grass Collection
Remove the grassbag and operate the mower with the rear deflector
in the closed position.
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 Device
A friction device in the blade brake/clutch helps prevent damage
occurring to the cutting mechanism when a hidden obstruction or over-
load is encountered. When the obstruction or overload is removed, the
friction device will automatically reset.
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 cut-
terblade 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.
1.18

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.

MOWER MAINTENANCE
Lubrication
Lubricate the wheels, pivot points and linkages with engine oil every 25
operating hours.
Apply a good quality medium grease to the inner control cables at the
point of entry and exit from their outer casing.
Cutterblade Removal
Drain the fuel by running the engine until the fuel tank is empty and the
engine stops. Remove the spark plug lead and allow the engine to
cool. Turn the mower on its left hand side and ensure that the air clean-
er side of the engine is uppermost.
Firmly grip the end of the cutterblade with the gloved hand and remove
the two fixing screws and the cutterblade.
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 40Nm.
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.

MAINTENANCE
MOWER
Cutterblade Assembly
Assemble the cutterblade (2) with the turned up edges facing towards
the engine. Secure the cutterblade using two new fixing screws and
tighten to a torque of 40Nm.
To prevent accidents never reuse the fixing screws.

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.
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.
Cover the mower with a protective sheet and store it in a dry, ventilat-
ed area.
