How To Start - Use - Stop The Engine - Okay BF 43 Pro Mode D'emploi

IMPORTANT: Only use quality fuels and oils to maintain
high performance and guarantee the duration of the
mechanical parts over time.
• Petrol characteristics
Only use unleaded petrol with a fuel grade of at least
90 N.O.
IMPORTANT: Unleaded petrol tends to create deposits
in the container if preserved for more than 2 months.
Always use fresh petrol.
• Oil characteristics
Only use top quality synthetic oil specifically for two-
stroke engines.
Your dealer can provide you with oils which have been
specifically developed for this type of engine, and which
are capable of guaranteeing a high level of protection.
The use of these oils makes it possible to prepare a 2,5%
mixture, consisting in 1 part oil to 40 parts petrol.
• Preparation and preservation of the fuel mixture
DANGER! Petrol and the fuel mixture are highly
inflammable!
- Keep the petrol and fuelmixture in homologated
fuel containers, in safe place, away from any
flames or heat sources.
- Never leave the containers within the reach of
children.
- Never smoke whilst preparing the mixture and
avoid inhaling the petrol fumes.
The chart indicates the amount of petrol and oil to use to
prepare the fuel mixture according to the type of oil used.

To prepare the fuel mixture:
- Place about half the amount of petrol in a homol
gated tank.
- Add all the oil, according to the chart.
- Add the rest of the petrol.
- Close the top and shake well.
IMPORTANT: The fuel mixture tends to age. Do not
prepare excessive amounts of the fuel mixture to avoid
deposits from forming.
IMPORTANT: Keep the petrol and fuelmixture containers
separate and easily identifiable to avoid themistake of
using one in place of the other.
IMPORTANT: Periodically clean the petrol and fuelmix-
ture containers to remove any eventual deposits.

REFUELLING
DANGER! Never smoke whilst refuelling and
avoid inhaling the petrol fumes.
WARNING! Carefully open the tank top as pres-
sure could have formed inside.
Before refuelling:
- Shake the fuel mixture container well.
- Place the machine on a flat stable surface, with the
fuel tank cap facing upwards.
- Clean the fuel tank cap and the surrounding area to
avoid any dirt fromentering the tank during refilling.
- Carefully open the fuel tank cap to allow the pressure
inside to decrease gradually. Use a funnel to refill and
avoid filling the tank to the brim.
WARNING! Always close the fuel tank cap
firmly.
WARNING! Immediately clean all traces of fuel
which may have dripped on the machine or the
ground and do not start the engine until the petrol
fumes have dissipated.
