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. In-
spect the cutterblade for signs of damage.
Sharpen both cutting edges with a flat file to restore per-
formance. (Refer fig.30)

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.31)

If the cutterblade is not balanced the heavy end will
rotate downwards. Sharpen the heavy end until the
cutterblade is correctly balanced. (Refer fig.32)

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.33)

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 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.

- 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, 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.

- Cover the mower with a protective sheet and store it in a

dry, ventilated area.
