Important:
A loose spark plug can become
very hot and can damage the engine;
overtightening a spark plug may damage the
threads in the cylinder head.

Connect the wire to the spark plug.
Adjusting the Self-Propel
Drive
If the machine is new, does not self-propel, or it tends
to creep forward, adjust the drive cable.
1.
Move the machine outside and onto a paved
surface near a solid wall to safely prevent the
machine from moving forward while the engine
is running.
2.
Position the machine with the front tires against
the wall.
Note:
Ensure that the area is well ventilated
and clear of debris that could be thrown by the
machine.
3.
Shift the transmission to third gear.
4.
Start the engine; refer to
(page
15).
5.
Pull the self-propel-drive bar to the handle.
Note:
The wheels should start to turn as the
self-propel-drive bar just touches the handle.
6.
Shut off the engine.
7.
If you must adjust the machine, do the following:
•
If the wheels do not spin when you engage
the self-propel-drive bar, the traction belt is
too loose. Rotate the wheel-drive-control
knob

additional turn to allow for the normal stretching
of the belt during the break-in period.
Note:
You can skip this step if you are adjusting
a used belt.
Maintaining the Blade
Always mow with a sharp blade. A sharp blade cuts
cleanly and without tearing or shredding the grass
blades.
1.
Shut off the engine and wait for all moving parts
to stop.
2.
Disconnect the wire from the spark plug.
3.
Close the fuel valve by moving the fuel-valve
lever to the left
4.
Drain the fuel from the fuel tank.
5.
Tip the machine onto its right side (air cleaner
up) as shown in

Carefully examine the blade for sharpness and wear,
especially where the flat and the curved parts meet
(Figure
30A). Because sand and abrasive material
can wear away the metal that connects the flat and
curved parts of the blade, check the blade before
using the machine. If you notice a slot or wear
