INSTRUCTION MANUAL
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.
Excessive vibration when mowing is a
good indication of a problem with the
cutting system.
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.
Holding the blade firmly in one hand, use
a spanner or socket to loosen the blade
screw & rotate anti-clockwise.
The spark plug cap must be
removed before any attempt
is made to remove the blade
For best mowing results, have the edges
sharpened and the blade balanced at
least once a year by a specialist service
dealer or agent.
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.
Position the blade on its support with
the cooling fins facing the engine.
Check the correct alignment and
matching of pads with the blade.
The blade must be positioned
precisely on its stand.
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 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).
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.
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.
