WWW.BBTA.COM.AU BBT-SP70
MAINTENANCE & STORAGE
• NEVER store the mower with the tank filled with fuel in a closed room where fuel vapours may come into
contact with a strong heat source or flame. Allow the engine to cool before storing your mower in its storage
area.
• To reduce the risk of fire, clean the mower, especially the engine, muffler and fuel tank. Remove all traces
of grass or leaves.
• Check the condition of the grass collection bag frequently. Replace if it is damaged.
• If you need to empty the oil tank, carry out this operation outdoors.
• Wear thick gloves before mounting or sharpening the blade. Make sure the blade is still well balanced.
• Regularly check the oil level and add or replace if necessary.
• Inspect the mower frequently and make sure all grass deposits are removed under the crankcase.
• Check the blade often. For a clean mow, the blade must always be sharpened and well balanced.
• At regular intervals, check that all bolts and screws are tight to keep the mower in a safe operating condition.
Worn or loose nuts and bolts can cause severe damage to the engine or crankcase.
• If the blade bangs or rattles violently, stop the mower and service.
Blade
• The blade is made of hardened steel. For a clean mow, sharpen the blade frequently, approximately every 25
hours of use. Make sure the blade is always well balanced.
• Insert the small iron pin (2 or 3 mm in diameter) into the hole in the middle of the blade - the blade must
remain horizontal. If the blade does not remain horizontal, balance it by sharpening it further on the side
where it is leaning.
• To remove the blade, loosen the screw, check the blade bracket, and replace all parts if they are worn or
damaged.
• To sharpen the blade, place it in a clamp and file the sharp edges evenly, checking the balance of the blade.
• When reassembling the blade, make sure that the cutting edges are in the same direction as the direction of
rotation of the motor. The tightening torque of the blade screw should be 3.7 kg * m/s2(37 Nm) and can be
checked with a torque wrench.
Turn off the engine and remove the spark plug before servicing.
WARNING
Wear gloves, turn off the engine and remove the spark plug before proceeding.
WARNING
Use only original spare parts. Poor quality replacement parts can cause serious damage to your mower
and affect your safety. Contact our service agent to obtain specifications regarding the correct the correct
original spare parts.
WARNING

15
WWW.BBTA.COM.AUBBT-SP70
Spark Plug
• Check the spark plug 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 using a rotary motion and then remove the spark plug with the wrench provided.
• Clean off any carbon deposits using a copper brush and check the electrode gap with a feeler gauge.
• 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.
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 after every 25 hours of use, or more often if the engine is used in a dusty environment.
• Remove the air box lid and carefully remove the foam filter cartridge. Clean the cartridge in a small bowl of
warm water containing a few drops of dishwashing 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.
• 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 air box 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 maintenance of a 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.
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 transmission cable, increase or reduce the length of the adjustment device using
the key. Check the effectiveness of the transmission and the resistance of the lever.
• When the correct adjustment has been reached, secure the adjustment device by tightening the lock nuts.
Storage
• Clean and maintain the mower (as explained above) before storage.
• The mower must be parked and stored in a safe location, out of humidity and away from flammable or
dangerous material.
• Store the mower out of reach of children.
MAINTENANCE & STORAGE
NEVER clean the foam cartridge in petrol, white spirit or other solvents. These products will degrade the
filter cartridge.
