MOWER MAINTENANCE

Cutterblade Sharpening

A slightly worn cutterblade may be resharpened. 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.30)
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.31)
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.32)

Storage

Ensure that the cables do not become trapped at the pivot points
when collapsing the mower for 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. Depress the
engine stop lever to prevent it being damaged through contact

with the engine.
(Refer fi g.33)
Engines stored in excess of 30 days need to be protected with
Briggs & Stratton fuel additive or drained of fuel. This prevents
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 upon 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.
