b. Take care not to spill any gasoline on the engine or exhaust system when refueling.
c. Never refuel while smoking or in the vicinity of an open flame.
2. Never start the engine or let it run for any length of time in a closed area. The exhaust fumes are poisonous and may cause

3. Always turn off the engine before leaving the machine unattended and remove the ignition key. When parking the machine,
note the following:

c. Do not park the machine near a flammable source, e. g. a kerosene heater, or near an open flame. The machine could
catch fire.
4. When transporting the machine in another vehicle, be sure it is kept upright and that the fuel cock is turned to ìONî or ìRESî
(for vacuum type) / ìOFFî (for manual type).
If it should lean over, gasoline may leak out of the carburetor or fuel tank.
5. If you should swallow any gasoline, inhale a lot of gasoline vapor, or allow gasoline to get in your eyes, see your doctor
immediately. If any gasoline spills on your skin or clothing, immediately wash it off with soap and water and change your
clothes.
