6. When the engine starts, regulate the throttle and the
ground speed control as desired.
Stopping the Engine
1. Release the blade control bail and move the throttle
control to the
(Off) position.
2. Disconnect the wire from the spark plug if you do not
use the lawn mower or if you leave it unattended.
Operating the Blade and the
Self-Propel Drive
1. Have the blade control bail in the A position (Fig. 10).
Figure 10
2. Slide the blade control bail to the right and raise it to
the B position to engage the blade (Fig. 10).
3. Squeeze the blade control bail against the handle to the
C position to drive (Fig. 10).
Note: To disengage the traction drive but keep the blade
engaged, gradually release the blade control bail to the B
position. To self-propel with the blade disengaged,
squeeze the blade control bail against handle to the C
position without sliding the blade control bail to the right.
The lawn mower has three ground speeds: 1 is slow, 2 is
medium, and 3 is fast. The ground speed control is located
at the rear of the belt cover (Fig. 8).
Note: You can vary the ground speed by increasing or
decreasing the distance between the blade control bail and
the handle. Lower the blade control bail to slow the lawn
mower when making a turn or if the lawn mower is
moving too fast for you. If you lower the blade control
bail too far, the lawn mower stops self-propelling.
Squeeze the blade control bail closer to the handle to
increase the ground speed. When you hold the blade
control bail tight against the handle, the lawn mower
self-propels at the maximum ground speed. Move the
ground speed control to the
you use the lawn mower for trimming and when you leave
the lawn mower.
Using the Discharge Tunnel
Plug
1. Stop the engine and wait for all moving parts to stop.
2. Insert the plug; refer to Installing the Discharge Tunnel
Plug on page 5.
3. To remove the plug, move the discharge door handle
rearward and lift up the spring clip on the bottom of
the plug. When the plug is unlocked, pull it out of the
discharge tunnel.
Note: When the grass is thick and lush, clippings may
collect on and around the discharge tunnel plug. This may
make removing the plug difficult. Clean the plug
thoroughly after each use.
Checking the Blade Brake
Clutch
Check the blade brake clutch (BBC) system before each
use to ensure that it is operating properly.
