When the ground drive clutch lever is disengaged the
mower may be pushed. This feature is useful when mow-
ing in conned areas.
Ground speed may be adjusted by operating the engine
speed control. Push forward to speed up and pull back to
slow down.
Only operate the lever with the engine running to prevent
damage.
If the engine stop lever is released the engine will stop.
(Ref g. 11)
Reverse Travel
Release the ground drive clutch lever. Hold and pull
against the handlebar with both hands to reverse the
mower.
Turning
To make a wide turn steer the mower with the handlebar
in the direction required.
To make a tight turn release the ground drive clutch
lever, apply downward 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 excessively when making a turn. Never raise
the rear of the mower when the engine is running.
Stopping
Release the ground drive clutch lever 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, disconnect the spark plug lead. (Refer g.12)

Fig. 13
Height Of Cut
To adjust the height of cut: Grip the lever and pull side-
ways to disengage it from the locking notch, then push
forwards to lower or pull backwards to raise the height
of cut. Finally release the lever at the required position
and ensure it locks rmly into one of the eight setting
notches.
Always select a height of cut to suit operating conditions.
Aim to prevent engine overloading and blockages by
avoiding low cuts in long grass conditions. Be prepared
to make two cuts when the grass is long. (Refer g.14)
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 obstructions which
when contacted by the cutterblade could risk health
and safety or result in damage to the mower. Remember the location of these obstructions and ensure that
you mow around them. (Refer g.15)
Grassbag
Raise the rear deector and lift the grassbag and lower
the rear deector 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 ow through the
grassbag. When collecting grass clippings it is important
that the grassbag is emptied regularly to prevent blockages and engine overloading. (Refer g.16)
Without Grass Collection
Remove the grassbag and operate the mower with the
rear deector in the closed position. (Refer g.17)
Heavy Growth
Areas of heavy growth should be mown without
collecting the clippings. If collection is required, rst
mow the area without the grassbag 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 tted. Reduce the height of cut
and mow the area again as necessary until the required
nish is obtained.
To prevent damage to your lawn do not remove more
than one third of grass height in one cut. (Refer g.18)
Friction Disc
The cutterblade is driven by the engine via a friction
disc to help prevent damage occurring to the engine
crankshaft and cutting mechanism when a hidden
obstruction or overload is encountered. (Refer g.19)
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. (Refer g.19 & 20)

MOWER MAINTENANCE
Carburettor Adjustments
Should only be made by an authorised Briggs & Stratton
dealer. Under no circumstances should the engine be
adjusted to run at a speed in excess of that shown on the
Declaration of Conformity.
Oil Service
Check the oil level daily before starting the engine and
ensure that the correct oil level is maintained. Refer to-
‘Before Starting the Mower’ for oil checking and lling
instructions.
Change the engine oil after the rst 5 hours of operation
and thereafter according to the ‘Maintenance Schedule’:-
1. Drain fuel by running the engine until the fuel tank is
empty.
2. Remove the spark plug lead.
3. Allow the engine to cool.
4. Drain the oil while the engine is warm (not hot)
5. Tip the mower over on to its right hand side thus
ensuring that the air cleaner is kept uppermost to
prevent engine damage.
6. Remove the oil ller dipstick and drain the oil into a
suitable container.
7. Rell with new oil of the recommended SAE viscosity grade. (Refer to-‘Before Starting the Mower’)
(Refer g.22)

Spark Plug Service
Use only Briggs & Stratton (Part number 19368) spark
tester (1) to check for a spark as shown in the diagram.
(Refer g.24)
Replace the spark plug every 100 hours or every season,
whichever occurs rst. A spark plug wrench is available
from any authorised Briggs & Stratton service dealer.
Check the spark plug gap with a feeler gauge and set at
0.50mm. (Refer g.25)
Keeping Engine Clean
Remove all grass and debris from the engine including
the exhaust/exhaust guard, the air ways in the top cowl
and the surrounding deck areas on a daily basis after
use. Never spray the engine with water during cleaning.
Water can contaminate the fuel. Always clean with a
brush or compressed air. (Refer g.26)
Grass and debris may clog the engine’s air cooling
system especially after prolonged operation while cutting
tall, dry grass. The internal cooling ns and surfaces
may require cleaning to prevent overheating and engine
damage. We recommended that this service be carried
out by an authorised Hayter Service dealer.
Grassbag

Securing Nuts & Bolts
Regularly check that all securing nuts and bolts are tight.
Replace missing or damaged items immediately.
Clutch Cable Adjustment
At any time the operator feels that the machine is loosing
drive:
1. Stop the engine.
2. Pull the machine backwards at the same time
progressively engage the clutch lever until the rear
rollers lock, at this point the clutch lever should be
60mm from the handlebar.
3. If the distance between the clutch lever and handlebar
is less than 60mm regulate the engagement position
with the black plastic cable adjuster. To regain the
60mm distance (Refer g.29 & 30)
4. Note this is a temporary adjustment and at the nearest
opportunity a service should be carried out to ensure
the spring on the clutch cable attached to the gearbox
clutch is set correctly. This adjustment should be done
using the metal adjuster at the control with the plastic
adjuster reset fully wound in. When the spring is set
tighten the inner lock nut to secure position. (Refer
gs.31 & 32)
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
right hand side and ensure that the air cleaner side of the
engine is uppermost. (Refer g.33)
Firmly grip the end of the cutterblade with a gloved hand
and remove the bolt, spring washer and distance piece
securing the cutterblade with a 9/16” A/F spanner. (Refer
g.34)
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 cutting
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 cutterblade 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 specied 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
Assemble the cutterblade with the turned up edges facing
towards the engine. Secure the cutterblade using the bolt
(1), spring washer (2), and distance piece (3). (Refer
g.34)

Cutterblade Sharpening
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 at le to restore performance. (Refer g.35)
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.
(Refer g.36)
If the cutterblade is not balanced the heavy end will
rotate downwards. Sharpen the heavy end until the
cutterblade is correctly balanced. (Refer g.37)
Storage
To store the handlebar unscrew the 2 small securing
knobs sufciently 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 damaged
through contact with the engine. (Refer g.38)
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 ns, under top cowl, around and behind exhaust/exhaust guard and ensure that the grassbag is clean.
- Lubricate the mower and treat metal parts with a water
repellent anti-corrosion product.
- Cover the mower with a protective sheet and store it in a
dry, ventilated area.

Fig. 38
14 15
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 rst cut can be made. The rst cut should merely
“top” the grass as close cutting at this stage could result
in severe yellowing or browning. Two cuts are generally
sufcient 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 selective 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 general 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.
August
Keep mowing regularly and watering as necessary. Fill
any cracks caused by drought with a mixture of sharp
sand and soil. In dry weather 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
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.
To prevent grass damage do not remove more than
one third of the grass height in one cut.
