Vertical Engine

4.  Grip the Starter Handle of the Engine loosely and pull it 

gently until resistance is felt. Allow Cable to retract fully 

and then pull it quickly. Repeat until the engine starts.

Note:

 Do not let the Starter Handle snap back against the 

engine. Hold it as it recoils so it doesn't hit the engine.

5.  Allow the Engine to run for several seconds.  Then, 

if the Mower’s choke control is in the CHOKE 

(START/CLOSED) position, move the choke control 

very slowly to its RUN (OPEN) position. 

NOTE:

 Moving the Choke Lever too fast could stall the engine.

IMPORTANT:

  Allow the engine to run at no load for a minute or two with no load  

after each start-up so that the engine can stabilize.

6. 

Break-in Period:

a.  Breaking-in the engine will help to ensure proper equipment and engine operation.
b.  The operational break-in period will last about 3 hours of use.  During this period:

•  Do not apply a heavy load to the equipment.

c.  The maintenance break-in period will last about 20 hours of use.  After this period:

•  Change the engine oil.

Under normal operating conditions subsequent maintenance follows the  

schedule explained in the MAINTENANCE AND SERVICING section.
