8.1 Starting and Stopping the Lawnmower
!
WARNING! The lawnmower's exhaust gas contains
toxic substances. Do not run the engine in closed or
poorly ventilated areas.
!
WARNING! The lawnmower blade begins to rotate as
soon as the engine is started.
!
WARNING! Before starting engine, check the lawn-
mower blade to make sure that it is securely fastened.
!
WARNING! Keep hands, feet, hair and clothing away
from all the moving parts of the lawnmower.
!
NOTE! To start the engine, make sure that the spark plug
boot is located on the spark plug and the engine is filled
with sufficient recommended oil and fuel.
!
WARNING! Running engines produce heat. Engine
parts, especially the muffler, become extremely hot.
Severe thermal burns can occur on contact.
!
WARNING! The blade continues to rotate for a few sec-
onds after the engine control lever is released.
!
NOTE! In order to avoid any unintentional start-ups, this
lawnmower is fitted with an engine break;
• Running the engine to power the cutting blade requires
the engine control lever to be held against the upper
handle (without an operator present, the machine will not
run).
• To stop the engine (and blade), release the engine con-
trol lever. The lever will return to its original position which
automatically switches off the engine.
Each time the lawnmower is used, check the operation of the
engine control lever and braking system before starting to
mow;
