INSTRUCTION MANUAL
Holding the blade firmly in one hand, use
a spanner or socket to loosen the blade
screw & rotate anti-clockwise.
Wear appropriate protective gloves to
prevent possible injury when handling
the blade. Disconnect the spark plug cap
and tilt the mower on its side with air
filter and carburettor side uppermost.
Before and after each mowing session,
check that the blade, its attachment
bolts and drive shaft are not damaged
or excessively worn. Never try to
straighten a bent blade. Replace a
damaged, worn or bent blade as soon
as possible. Use only genuine WEBB
parts or those approved by WEBB.
Wear appropriate protective gloves to
prevent possible injury when handling
the blade. Disconnect the spark plug cap
and tilt the mower on its side with air
filter side uppermost.
Check that all components (the blade,
key, blade holder, screws and washers)
are present, clean and in good condition.
Tighten the screws connecting all of
the components. Make a final visual
check that all parts are present and
aligned before tightening the fixing
bolt very firmly with a wrench while
holding the blade firmly in one hand
(NB wear suitable gloves).
Rotate clockwise
Check the correct alignment and
matching of pads with the blade.
The blade must be positioned
precisely on its stand.
Position the blade on its support with
the cooling fins facing the engine.
For best mowing results, have the edges
sharpened and the blade balanced at
least once a year by a specialist service
dealer or agent.
Excessive vibration when mowing is a
good indication of a problem with the
cutting system.
Check the spark plug initially after the
first five hours of mower use.
Thereafter, maintenance of the spark
plug should take place every 25 hours.
Remove the spark plug cap (Fig.15)
using a rotary motion and then remove
the spark plug with the wrench provided
(Fig.16).
If the spark plug is worn or damaged,
replace with a new spark plug of the
same or suitable type for the engine.
If in doubt, contact your point of
purchase or local dealer.
Clean off any carbon deposits using a
copper brush and check the electrode
gap with a feeler gauge (the gap should be
≈ 0.7 mm). Replace and tighten the
serviced spark plug and replace the cap.
The spark plug cap must be
removed before any attempt
is made to remove the blade
BASIC MAINTENANCE
An air filter in poor condition will reduce
the performance and life of the engine
while making it harder to start.
Regular checks are therefore essential,
especially when using the mower in dusty
conditions. Check and clean the air filter
every 25 hours of use or more often if
the engine is used in a dusty
environment.
Clean the cover and inside of the air filter
box with a clean lint-free cloth. Apply a
uniform layer of oil to the outside of the
cartridge filter with a brush (you can use
clean engine oil). Insert the filter cartridge
into its housing and replace the filter lid,
ensuring that each component is in place
and properly installed. If the filter cartridge
is damaged or is very dirty, replace it using
a genuine part.
The first oil change should be carried out
after the first 5 hours of mower use.
Thereafter, change the oil after every 25
hours use or at least once a year.
Leave the engine running outdoors for
several minutes to warm the oil and
make it more fluid.
To adjust the tension of the cable
trasmission, increase or reduce the
length of adjustment device using
the spanner
(fig. 19) . Check the
effectiveness of the transmission and
resistance of the lever.
Once a proper adjustment has been
reached, secure the adjustment device
by tightening the lock nuts.
If the transmisison cable is too tight,
it will be difficult to move the drive
lever towards the handlebars.
Conversely, if the transmission cable is
not tight enough, the transmission will
function poorly and lack power.
In its transmission-engaged position
(fig. 18), the mower’s brake lever is
pushed fully towards the handlebar.
An incorrectly-adjusted transmission
cable can cause premature wear to the
mower’s drive system.
Remove the spark plug cap and
unscrew the oil level dipstick.
Place a suitable container beneath the
mower’s oil filler pipe and tilt the mower
onto its side with the air filter and
carburettor uppermost.
Allow the oil to drain completely into
the container. Return the mower
onto its four wheels and fill the
engine with new oil.
The oil level should be between the
minimum and maximum oil level marks
on the dipstick
(fig.21) . Add oil if
necessary and repeat the above
checking process. Running the engine
without oil or with too little oil can
cause serious engine damage.
Position the mower on a firm, level
surface. Unscrew the oil level dipstick
(fig.20) and wipe dry. Insert the dipstick
until it reaches the filler neck, but do not
screw in. Remove the dipstick and check
the oil level holding the dipstick horizontal.
Remove the air filter cover lid and carefully
remove the foam filter cartridge.
Clean the cartridge in a small bowl of
warm water containing a few drops of
washing-up liquid until it is perfectly clean
and free from all traces of grease and dust.
Rinse the filter cartridge in clean water and
then squeeze gently to remove most of the
water. Let it air dry until it is completely dry.
