MOWER MAINTENANCE
Cutterblade Removal continued
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 specifi ed torque of 54Nm.
Replace the cutterblade every 2 years or sooner or 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), distance piece (3) and tighten to a torque of
54Nm.
(Refer fi g.30)

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 fl at fi le to restore performance.
(Refer fi g.31)
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 fi g.32)
If the cutterblade is not balanced the heavy end will rotate
downwards. Sharpen the heavy end until the cutterblade is
correctly balanced.
(Refer fi g.33)

Storage

To store the handlebar, unscrew the 2 small securing knobs
suffi ciently 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.
(Refer fi g.34)
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
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 cylinder and replace the spark plug. Do not exceed the stated
volume of oil as engine damage may occur on restarting. 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 fi 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.
