OPERATING THE MOWER
Slopes
To prevent engine damage do not use the mower on
slopes greater than 20 degrees. (Refer fig.13)
Grassbag
Raise the rear deflector and lift the grassbag and lower
the rear deflector to rest against the rear of the mower.
Blade Brake Clutch
A device in the blade brake clutch helps minimise
damage to the cutting mechanism when a hidden
obstruction or overload is encountered. When the
obstruction or overload is removed, the device will
automatically reset. (Refer fig.19)
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 prevent block-
ages and engine overloading. (Refer fig.16)
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 firmly into one of the eight setting
notches.
Always stop the engine when a hidden obstruction
or excessive vibration is encountered. Disconnect the
spark plug lead and examine the cutting mechanism.
ALWAYS replace a damaged cutterblade - Refer to
“Maintenance”.
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 fig.14)
Without Grass Collection
Remove the grassbag and operate the mower with the
rear deflector in the closed position. (Refer fig.17)
Non Grassed Areas
When moving the mower across non-grassed areas, stop
the cutterblade and set the mower to the maximum height
of cut to protect the cutting mechanism.
Heavy Growth
Before Mowing
Areas of heavy growth should be mown without
collecting the clippings. If collection is required, first
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 fitted. Reduce the height of cut
and mow the area again as necessary until the required
finish is obtained.
To prevent accidents, thoroughly inspect the area
and remove all objects which when contacted by the
mower cutterblade could become dangerous projec-
tiles. Inspect the area for hidden obstructions which
when contacted by the cutterblade could risk health
and safety or result in damage to the mower. Remem-
ber the location of these obstructions and ensure that
you mow around them. (Refer fig.15)
To prevent damage to your lawn do not remove more
than one third of grass height in one cut. (Refer fig.18)

Clutch Cable Adjustment
At any time the operator feels that the machine is loosing
drive:
1.Stop the engine.
Regularly check that the bolt securing the cutterblade is
tightened to the specified torque of 55Nm.
Cutterblade Removal
Replace the cutterblade every 2 years of sooner if
excessively worn or damaged.
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 cleaner side of the
engine is uppermost. (Refer fig.34)
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.
To prevent injury it is wise to seek assistance when
turning the mower on its side.
Cutterblade Assembly
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 fig.30 & 31)
Remove the two socket head screws (1), and Former
BBC blade (2) and plate clamp BBC (3). (Refer fig.35)
Assemble the two socket head screws (1), Former BBC
blade (2) and Plate clamp BBC (3). Tighten to a torque of
55Nm. (Refer fig. 35)
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.
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
figs.32 & 33)
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.

MOWER MAINTENANCE
Engines stored in excess of 30 days need to be protected
Cutterblade Sharpening
with Briggs & Stratton fuel additive or drained of fuel to
prevent gum from forming in the fuel system or on essen-
tial 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.
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. In-
spect the cutterblade for signs of damage.
Sharpen both cutting edges with a flat file to restore per-
formance. (Refer fig.36)
- Drain fuel from the engine by operating the engine until
it stops.
- Disconnect the spark plug lead.
Ensure that the cutterblade is balanced. Use a screw driv-
er 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 fig.37)
- 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, around and behind ex-
haust/exhaust guard and ensure that the grassbag is clean.
- Lubricate the mower and treat metal parts with a water
repellent anti-corrosion product.
If the cutterblade is not balanced the heavy end will
rotate downwards. Sharpen the heavy end until the
cutterblade is correctly balanced. (Refer fig.38)
Storage
To store the handlebar unscrew the 2 small securing
knobs sufficiently to allow it to be pivoted forwards to
rest against the mower. Take care to ensure that the con-
trol 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 fig.39)
- Cover the mower with a protective sheet and store it in a
dry, ventilated area.

LAWN CARE CALENDAR
To be used as a guide only
January
June
October
Rake out the thatch from the turf and spike the lawn to
assist in drainage. Brush in peat and sharp sand.
There is very little work to do this month apart from
brushing away leaves. Keep off the grass if frozen or
waterlogged.
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.
November
February
Use a stiff broom to disperse worm casts before mowing.
Keep turf free from leaves.
Rake the grass thoroughly. Spike the lawn to aerate and
stimulate soil organisms and root growth and apply lawn
sand if necessary.
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.
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.
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
sufficient this month.
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.
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.
April
Mow often enough to stop grass growing away. Dig out
patches of coarse grass or resistant weed. Re-seed bare
patches.
September
Raise the height of cut to allow the grass to thicken and
protect the roots from the winter frost and snow.
To prevent grass damage do not remove more than
one third of the grass height in one cut.
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.
