MOWERTHESTARTING

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.

Always use high quality detergent oil classified SAE 30 oil. Never use
additives with recommended oil.
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’.

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.

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 ser­vice dealer.

Fill to base of neck to allow for fuel expansion. Do not overfill the

Hold and pull against the handlebar with both hands to reverse the
mower.

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.

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’ posi­tion and disconnect the spark plug lead.

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.

OPERATING THE MOWER

Without Grass Collection

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.

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 pre­vent blockages and engine overloading.

Remove the grassbag and operate the mower with the rear deflector in
the closed position.

Non-Grassed Areas

STOP

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 damage to your lawn do not remove more than one third
of grass height in one cut.

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.

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”.

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.

1.20

There is very little work to do this month apart from brushing away
leaves. Keep off the grass if frozen or waterlogged.

Rake the grass thoroughly. Spike the lawn to aerate and stimulate soil
organisms and root growth and apply lawn sand if necessary.

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.

Mow often enough to stop grass growing away. Dig out patches of
coarse grass or resistant weed. Re-seed bare patches.

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.

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.

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.

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.

Raise the height of cut to allow the grass to thicken and protect the
roots from the winter frost and snow.

Rake out the thatch from the turf and spike the lawn to assist in
drainage. Brush in peat and sharp sand.

Use a stiff broom to disperse worm casts before mowing. Keep turf
free from leaves.

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.

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 cross­cutting keeps down the coarse weed grasses.

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

Use only Briggs & Stratton spark tester (1) to check for a spark as
shown in the diagram.

Replace the spark plug every 100 hours or every season, whichever
occurs first. 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 0.76mm.

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.

Grass and debris may clog the engine’s air cooling system especially
after prolonged operation while cutting tall, dry grass. The internal cool­ing fins and surfaces may require cleaning to prevent overheating and
engine damage. We recommended that this service be carried out by an
authorised Briggs and Stratton dealer.

Remove grass debris from the grassbag immediately after use and
check its condition for signs of damage.

To prevent accidents replace a damaged grassbag immediately.

Remove grass debris from the top and underside of the deck housing
immediately after use.

Fertilisers and top dressings are particularly corrosive.
Thoroughly clean the mower deck immediately after use on treat­ed grass and store well away from corrosive materials.

Regularly check that all securing nuts and bolts are tight. Replace
missing or damaged items immediately.

First slowly pull the mower backwards whilst doing this, gently start

to move the clutch lever towards the handlebar by 10 - 20mm. If no

resistance can be felt.

Unscrew the middle section of the black adjuster until the clutch

lever is set correctly.

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.

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.
Firmly grip the end of the cutterblade with the gloved hand and remove
the bolt, spring washer and distance piece securing the cutterblade with
a 9/16” A/F spanner.

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
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 Removal

1.28

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) and tighten to a torque of 54Nm

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.

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 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, ventilat­ed area.

MAINTENANCE

(412 only) - PREVENT ACCIDENTS: ALWAYS charge the bat­tery in a well ventilated area.

NEVER charge the battery near naked flames or direct heat.

ALWAYS switch off the mains electricity supply before discon­necting 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 fourteen 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 bat­tery 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.
