OPERATING THE MOWER  
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, Autodrive  
model), 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 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 and the engine stop lever.  
Emergency stop - If the engine fails to stop, disconnect the spark  
plug lead.  
STOP  
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 nine 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.

OPERATING THE MOWER  
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  
Lift the grassbag through the handlebar and close 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.  
Heavy Growth  
To prevent engine overloading and blockages be prepared to make two  
cuts in areas of heavy growth. If collection is required, first 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 grass damage do not remove more than one third of grass  
height in one cut.

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

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 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 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.

Cutterblade Sharpening  
Continued.  
If the cutterblade is not balanced the heavy end will rotate downwards.  
Sharpen the heavy end until the cutterblade is correctly balanced.

Storage  
To store the handlebar unscrew the 2 small securing knobs sufficient-  
ly to allow it to pivot 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 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.
