Tips on mower safety
WARNING! The information contained within this safety section is
extremely important. Personal injury to the user and to others may
result if this section is not read and acted upon at all times.
1. Before starting your mower inspect it carefully to ensure that there are no loose
parts and that it is in good working order.
2. Be sure of your footing. Always walk when operating the lawnmower, never run.
3. Clear the area to be mowed of any stones, sticks, wire and debris before
beginning, and always ensure that you mow a safe distance away (over 14 metres)
from adults, children and animals.
4. Keep hands, feet and clothing away from the mower’s moving parts, and always
wear appropriate footwear (do not wear sandals, open or soft shoes).
5. Never put your hands or feet underneath the chassis of the lawnmower while the
engine is running.
6. Be aware that the machine’s exhaust area and other parts of the lawnmower get
very hot during use, and will remain hot after use.
7. Turn off the engine and disconnect the spark plug cap before cleaning,
transporting, or making adjustments, and never leave the mower unattended.
8. Mow across the face of slopes, not up & down, and avoid mowing on very steep
slopes. We recommend you avoid mowing when it is raining, or after nightfall.
9. Do not operate the machine by pulling it towards you as you risk pulling it on to
your feet. Instead, always push and walk behind your lawnmower.
10. Do not fill the tank, or start the lawnmower indoors, or in a poorly ventilated area,
as exhaust gases contain poisonous substances and petrol fumes are flammable
and dangerous.
11. Use unleaded petrol that is not more than 3 months old. Do not fill the tank completely.
Use a funnel. Clean up any overflow or splashes before starting the engine or storing.

User’s manual 7
12. To inspect the underside of your mower, only tilt the lawnmower backwards when
standing behind it (this is the side where the exhaust is near the ground) otherwise
oil may leak into inappropriate areas of the engine. Never tilt the lawnmower when
the engine is running.
13. Turn off the engine before emptying the grass-catcher, and before clearing any
grass caught in the rear flap where the catcher fits.
14. Do not alter the engine governing settings or over-rev the engine, as excessive speed
is dangerous and can reduce engine life.
15. Never open the fuel filler cap, or fill the tank, if the engine is still hot after use. And
please ensure that you securely tighten the petrol cap after filling.
16. Do not transport the mower in a vehicle if there is any petrol in the tank.
17. Store fuel and oil in a cool well-ventilated place, away from direct sunlight and not
near gas cylinders or hot water heater systems.
18. Do not smoke when filling the fuel tank, using the machine, or when petrol is in the
immediate area. And never use or store the mower near a naked flame.
19. Webb recommends that you wear a safety helmet, ear protectors, safety goggles
and safety boots when using a lawnmower. These are available on 01793 333212.
20. All servicing and repair work under warranty must be carried out by an Authorised
Webb Dealer, otherwise the 2-year warranty may be void. You can find your
nearest dealer at www.webblawnmowers.co.uk.

Before you begin.
WARNING! The following procedures must be carried out before you
start the engine of your lawnmower.
1. Fill oil sump with oil.
The mower is NOT supplied with oil in
the engine, add 569ml SAE30 oil before
starting the engine for the first time.
Firstly, remove the warning label from under
the dipstick, then remove the dipstick and
slowly pour 569ml SAE30 oil into the oil
filler. Replace the dipstick and tighten.
Before you use the mower each time, check
the oil level and if necessary top up with
SAE30 engine oil. To check the oil level, just
unscrew the yellow dipstick, wipe clean and
replace into the oil filler, remove it again to
check the oil level. The oil level must be
between the min and max marks on the
dipstick.

2. Fill fuel tank with unleaded petrol.
Petrol is highly flammable so extreme caution must be
taken when handling it. Always store petrol in approved
containers and you must ensure that you use fresh
petrol that is less than three months old. Do not mix oil
with petrol.
To put petrol in the fuel tank, firstly remove the warning
label from under the petrol cap. It’s best to fill the tank
using a clean funnel, but never fill it completely. Instead,
leave at least 13mm from the bottom of the filler neck to
allow for expansion. Ensure that you securely tighten the
petrol cap after filling.
3. Attach the grass catcher.
The grass catcher attaches easily by
lifting the mower’s rear deflector and
inserting the grass catcher.
Just lift the rear deflector with one hand
and then gently slide the catcher into
position (as shown in photo on right).

Cutting height adjustment.
WARNING! Turn mower off before adjusting cutting height lever.
Your lawnmower’s height adjustment is positioned on
the rear left side. There is a single 6-position lever
that adjusts all four wheels at the same time.
The lower the level, the shorter the cut. For very thick
or moist grass, you should selecta higher setting than
usual to avoid clogging and stalling the lawnmower
under the extra cutting load.

User’s manual 11
Starting the engine.
WARNING! Keep hands, feet, and clothing well away from moving parts,
the exhaust, and the engine cowling. Refer to ‘Tips on mower safety’ on
pages 6 and 7for more information.
1. Make sure that your mower is on a safe, flat area (a paved area or path is ideal
– avoid thick wet grass and gravel surfaces) to make starting safe.
2. Move the throttle control lever located on the handle to the ‘Cold Start’ position.
3. Slide the ‘Red’ petrol tap lever to the left ‘On’ position.
4. Firmly hold the top handle with one hand, and then with your other hand pull the
cord slowly until you feel resistance. Then pull vigorously.
5. When the engine has been running for at least15seconds (more time oncold days)
adjust the throttle control lever to the ‘Run’ position.
6. To re-start a hot engine, move the throttle control lever to the ‘Hot Start’ position
andthen refer to ‘Point 4’ above.
7. To turn off your mower, slide the throttle control lever down to the ‘Stop’ position.
After it has stopped, slide the ‘Red’ petrol tap lever to the right ‘Off’ position.

Basic maintenance made easy.
WARNING! If your mower is not serviced correctly, you could reduce
your mower’s ability to operate and void warranty.
1. Spark plug.
Firstly, wait until the engine has cooled
before disconnecting the spark plug cover
and then removethe spark plug with the
box spanner supplied. If it is dirty, you can
clean the plug with a wire brush.
For best results we advise you to replace
the spark plug after 100 hours of use. The
replacement spark plug is NGK B4LM.
When refitting the spark plug do not over-
tighten. If adjusting yourself, note the spark
plug gap must be set to 0.75mm.
2. Air filter.
Ensure the engine is cool, unscrew the top
air filter nut, lift up the cover and remove
the air filter element. Put the cover back on the
housing immediately to prevent any objects
falling into the air intake.
Either carefully brush off any excess dirt
particles, or replace the air filter with a new
one. To protect your warranty, only use
a genuine B&S air filter. We recommend
that you replace the air filter after every 12
months of regular usage. When the air filter
has been cleaned or replaced, screw-in the
cover, taking care not to over-tighten.

3. Cleaning ABS deck often.
As the ABS material can be marked by petrol, please clean the deck immediately whenever you
find petrol on the deck or before storing.
