3.1 Preparing the mower for work
3.11 Mower assembly
1. Mower shown in delivery
position with handlebars folded (fig.1)
2. Attach the handlebars using the
key supplied (fig.2)
3. Lock the handlebars in position
using quick-release clamps (fig.3)
4. Fasten the starter cord to its support (fig.4)
3.12 Filling the mower’s engine with oil
For transport reasons, your new mower’s engine does not contain oil when
despatched from the factory. Before use, ensure that the mower contains oil.
Please refer to the Briggs & Stratton owners manual supplied with the LBP46 for any engine
related questions on this machine
WARNING: Never run the engine without oil even for a short period.
Always use a high quality oil of API SF
standards and SAE30 or 15W40 viscosity.
When filling the engine with oil, position
the mower on a firm, level surface
Unscrew the oil filler cap and remove the
dipstick (fig.5).
Slowly pour in the oil. The correct capacity
of the engine’s oil sump is 650 ml.
Insert the dipstick up to the filler neck but
do not screw it in. Remove the dipstick and
read the oil level by holding the dipstick
horizontally. The oil level must reach the maximum mark on the
dipstick (fig.6).
If too much oil has been added to the engine, the excess can be drained
out by tipping the mower onto its side with the air filter and
carburettor uppermost.

10 / User’s Manual Sanli LS42 - LSP42 - LSP46-LBP46
3.13 Filling the fuel tank
WARNING: Petrol is highly inflammable. Always handle fuel with extreme
care to avoid risk of burns, fire or explosion. The fuel tank should be filled
before starting the engine. Your mower’s engine runs on petrol alone - do not
add oil to the petrol.
Always use unleaded petrol of a minimum 95 RON. Buy only the quantity of
fuel that you plan to use in a month. Never transport and store petrol other
than in a container suitable for the purpose, approved and labelled
accordingly.
Always refuel outdoors, never in an enclosed space or near a naked
flame or heat source. Never smoke while filling the fuel tank.
Do not unscrew the tank cap when the engine is running or when the
mower is hot.
To add fuel, unscrew the fuel filler cap.
Slowly pour the fuel into the tank using the
fuel container’s spout (fig. 7) or a funnel.
The tank’s capacity is about 1 litre. Avoid
spillages by not overfilling the tank. Leave
about 13 mm space beneath the threaded
collar to allow for fuel expansion.
If fuel should overflow, do not start the engine. Move the mower away
from the place of spillage and carefully wipe down the mower. Any
attempt at starting should be avoided until petrol vapours have
completely gone.
Replace securely the caps on the fuel tank and the fuel container and
place the latter in a secure place away from heat or direct sunlight.
Before each mowing, visually inspect the condition of the mower’s fuel
tank and its cap, the fuel delivery pipe and the fuel filter.
If a fuel leak is seen or suspected, do not start the engine. Drain the fuel
tank using a fuel suction pump and immediately contact an approved
SANLI UK service dealer for advice.
NOTE: THE OIL FILLER CAP MUST BE SCREWED IN FULLY BEFORE STARTING
THE ENGINE. NEVER REMOVE THE FILLER CAP WITH THE ENGINE RUNNING.

User’s Manual Sanli LS42 - LSP42 - LSP46-LBP46 / 11
3.14 Adjusting the cutting height
For best results, always adjust the cutting height of your mower to suit the
mowing conditions and do not try to remove too much grass in one pass.
Adjustment of the cutting height for models LS42, LSP42 and LSP46 is made
centrally.
CAUTION: Never adjust the cutting height when the engine is running. Always
remove the spark plug cap before making any adjustments.
Take hold of the height of cut
adjustment lever positioned on the
mower’s right-hand rear wheel.
Move the lever outwards to release it
from its locating notch (fig.8).
Move the lever towards the front of
the machine to increase the cutting
height and towards the rear to reduce
the cutting height.
Return the lever to the locating notch to set the desired cutting height.
Make sure the handle fits snugly and securely into its serrated holder.
Obstructions such as grass clippings should not hinder his movement or
positioning.
3.2 Using the mower
Before starting and using the mower, check for the presence and operation of
safety devices. Also, check the condition of the blade and its securing bolt. If
necessary, replace or repair defective items. Use only genuine SANLI parts or
parts that have been approved by SANLI UK.
If possible, mow only when the grass is dry. If the grass is wet or excessively
long, perform two cutting passes. Make the first pass at maximum cutting
height to avoid overloading the mower. The second pass should be made at
the required finished height. If grass builds up beneath the mower’s chassis,
stop the engine and remove the spark plug’s cap before cleaning the
underside of the cutter deck.

12 / User’s Manual Sanli LS42 - LSP42 - LSP46-LBP46
3.21 Starting the mower
Before starting the engine, please read thoroughly the instructions
regarding safe use of the mower (see pages 5 –7).
Slide the throttle lever to and fro several times to ensure that it is
moving smoothly and correctly.
Check that the fuel tap is in the ON position (fig.9) and that the engine’s
oil level is correct (see paragraph 3.12).
Start the mower in a clear, level area. Do not start the engine if the
cutting blade is resting on rough and uncut grass as this may cause
difficulties at start-up.
For a cold start, move the throttle lever to the position marked:
For a hot start, move the lever to the position marked:
Stand behind the handlebars. Move the operator control lever
positioned in front of the handlebars rearwards so that the lever is
resting against the handlebars (fig.10). Take hold of the starter handle
firmly with the other hand.
Pull back the starter until you feel resistance and then pull the handle
firmly and briskly to turn the engine (fig.11).
Repeat the above procedure as necessary until the engine starts.
When starting from cold, gradually move the throttle lever to
the full throttle position (as shown right) after a few moments
of running.
WARNING: The cutting blade turns when the engine is being started.
3.22 Moving the mower
The LSP42, LSP46 & LBP46 mowers are equipped with a gearbox which allows
the mower to be self-propelled. When the transmission is activated, it
engages the rear wheels of the mower and the mower moves forward under
its own power.

User’s Manual Sanli LS42 - LSP42 - LSP46-LBP46 / 13
To activate the transmission, push the full-width
advance lever at the rear of the handlebar forwards
so that the lever presses against the handlebar
(fig.12).
While the machine is moving, hold the lever flexibly
so it can be released easily when needed.
To stop drive to the wheels, release the advance lever.
Note: The transmission operates only when the engine is running
To use the mower manually without driving the wheels, do not touch the
advance lever at the rear of the handlebar.
Similarly, when making U-turns, tight turns or when finishing off, release the
advance lever and move the mower across the ground manually.
3.23 Stopping the mower
To minimise possible risk of accidents, the engine of your SANLI lawnmower is
coupled to an operator control. When the operator control lever is released,
it returns immediately to its rest position and the engine is automatically
turned off.
To stop the mower, move the throttle lever to its stop position and
release the operator control lever. The engine and the blade will
stop turning automatically.
If there is a build-up of grass beneath the chassis, stop the engine, remove the
spark plug cap and wait until the engine has cooled before clearing the grass.
3.3 Cleaning, storage, transportation and maintenance
Before working on the cutting system of the machine, switch off the engine
and remove the spark plug cap.
3.31 Cleaning the mower
Cut grass is damp. Regular cleaning after each use will ensure better
functioning of the mower and reduce the risk of corrosion or seizure.
Having finished mowing, allow the engine to cool then remove
accumulated grass clippings from and around the engine with a brush.

14 / User’s Manual Sanli LS42 - LSP42 - LSP46-LBP46
Clean the grass collection bag annually with a brush or gentle spray of
water.
Disconnect the spark plug cap and tilt the mower on its side with the air
filter and carburettor uppermost.
Remove any remaining cut grass from the cutting system with a scraper
and a brush.
Reposition the mower onto its four wheels.
Do not use a pressure washer or hot water to clean the mower. Be
careful to avoid soaking parts such as the engine, air cleaner, wheel
bearings and metal fastenings. Dry off the machine before storing by
leaving it running for a few minutes on a flat, clear surface to prevent
corrosion or seizure.
3.32 Storing the mower
Store your mower in a dry, well-ventilated area, away from flames, sparks
or heat sources. If the storage area is accessible to children, immobilise
the machine by disconnecting the spark plug cap.
Storing the mower beneath a tarpaulin or similar cover is not
recommended as it may cause a build-up of condensation resulting in
corrosion of the mower.
Extended shutdown and winter storage
Thoroughly clean the mower. Ideally, run the engine outdoors until the
fuel tank is empty. Alternatively, empty any remaining fuel using a fuel
suction pump. Turn the fuel tap to the OFF position (fig 13).
Dispose of discarded fuel safely and responsibly, remembering that petrol
vapours can cause explosion or fire. Run the engine until any remaining
fuel is consumed. Allow the engine to cool. Check the condition and
cleanliness of the air cleaner (see page 17).
Remove the spark plug from the engine and pour a tablespoon of engine
oil into the cylinder. Gently pull the starter rope several times to turn over
the engine, distributing the oil to protect the cylinder over winter. Replace
and tighten the spark plug.
At the start of the new season
Remove the spark plug and gently clean off any carbon deposits from the
tip with a small copper wire brush, finishing off with petrol. Allow the
spark plug to dry. Pull the starter rope several times to expel excess oil

User’s Manual Sanli LS42 - LSP42 - LSP46-LBP46 / 15
from the cylinder. Replace and tighten the spark plug. Fill the fuel tank
with unleaded petrol (95 RON minimum) and move the tap to the ON
position. Turn over the engine until it starts (see 3.21)
Before transporting the mower
Thoroughly clean the mower. Empty the fuel
tank using a suction pump. Turn the fuel tap to
its OFF position (fig. 13). Dispose of discarded
fuel safely and responsibly, remembering that
petrol vapours can cause explosion or fire. Run
the engine until any remaining fuel is consumed.
Allow the engine to cool.
Remove the grass collection bag. Loosen the
quick release (fig.14) and fold down the top
section of the handles taking care not to bend
the cables.
To avoid scratching the mower, insert corrugated cardboard or similar
padding between the upper and lower handlebars and the engine.
Due to the mower’s weight, use ramps or seek assistance when lifting or
loading the mower.
3.33 Mower maintenance
Cutting system
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 SANLI parts or those approved by SANLI UK.
Excessive vibration when mowing is a good indication of a problem with the
cutting system.
WARNING: Vibration from a bent or damaged blade can cause costly damage
to the mower. Working with an excessively worn blade wastes fuel and can
lead to injury if the blade becomes detached from the machine.
Sharpening 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.
Removing the blade
Wear appropriate protective gloves to prevent possible injury when
handling the blade. Disconnect the spark plug cap and tilt the mower on

16 / User’s Manual Sanli LS42 - LSP42 - LSP46-LBP46
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.
Mounting the blade
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.
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).
Spark plug
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 retighten 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 a SANLI
UK appointed dealer.

User’s Manual Sanli LS42 - LSP42 - LSP46-LBP46 / 17
Air Filter
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.
Remove the air box lid (fig.17) 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.
WARNING: Never clean the foam cartridge in petrol, white spirit or other
solvents. These products will degrade the filter cartridge.
Clean the cover and inside of the air 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 for this). 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 SANLI part
WARNING: Do not twist the cartridge to clean foam, as you could damage it.
The SANLI LSP46 mower is equipped with a dual filtration system
comprising of the foam pre-filter and a cartridge filter paper.
The maintenance of the foam pre-filter is identical to that of a foam
cartridge filter, as described above. The cartridge filter paper should be
cleaned with a vacuum cleaner. If it is dirty or contaminated with oil or
petrol, replace it.
Clean the cover and inside of the air box with a clean cloth. Evenly apply a
thin layer of oil to the outside of the cartridge filter with a brush (you can
use clean engine oil for this). Replace the filter cartridge in its housing and
then replace the lid of the air box, ensuring that each component is in
place and properly installed.

18 / User’s Manual Sanli LS42 - LSP42 - LSP46-LBP46
Engine Oil
Checking the oil level
Position the mower on a firm, level surface.
Unscrew the oil level dipstick (fig.18) 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. The oil
level should be between the minimum and
maximum oil level marks on the dipstick (fig.19). 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.
Changing the oil
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. Warning: Parts of the engine will become very hot and can
cause severe burns.
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 as described in section 3.12
Note: Dispose of used engine oil carefully, responsibly and in accordance with
local or national regulations.
Adjusting the transmission cable
In its transmission-engaged position, the mower’s advance lever is pushed
fully towards the handlebar. An incorrectly-adjusted transmission cable can
cause premature wear to the mower’s drive system.
If the transmission cable is too tight, it will be difficult to move the advance
lever towards the handlebars. Conversely, if the transmission cable is not tight
enough, the transmission will function poorly and will lack power.
To adjust the tension of the cable transmission,
increase or reduce the length of the adjustment
device using the key (fig.20). Check the effectiveness
of the transmission and the resistance of the lever.
Once proper adjustment has been reached, secure
the adjustment device by tightening the lock nuts.

User’s Manual Sanli LS42 - LSP42 - LSP46-LBP46 / 19
Note: There should be about 2 cm of free-play before the advance lever
engages drive. The mower should begin to move forwards gradually from
that point onwards.
