it in for a second before releasing it (Figure 11).
5. Pull the starter handle lightly until you feel
resistance, then pull it sharply.
6. Regulate the throttle and the ground speed control
as desired when the engine starts.
Note: If the engine fails to start after 3 pulls, repeat
steps 2 through 6.

Stopping the Engine

1. Release the control bar 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 control bar in the A position (Figure 13).
Figure 13
2. Slide the control bar to the right and raise it to the
B position to engage the blade (Figure 13).
3. Squeeze the control bar against the handle to the C
position to drive (Figure 13).
Note: To disengage the traction drive but keep the
blade engaged, gradually release the control bar to the
B position. To self-propel with the blade disengaged,
squeeze the control bar against handle to the C position
without sliding the control bar to the right.
The lawn mower has 3 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 (Figure 12).
Note: You can vary the ground speed by increasing or
decreasing the distance between the control bar and the
handle. Lower the control bar to slow the lawn mower
when making a turn or if the lawn mower is moving too
fast for you. If you lower the control bar too far, the
lawn mower stops self-propelling. Squeeze the control
bar closer to the handle to increase the ground speed.
When you hold the control bar tight against the handle,
the lawn mower self-propels at the maximum ground
speed. Move the ground speed control to the Neutral
position when you use the lawn mower for trimming
and whenever 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.
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 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 control bar before each use to ensure that
the blade brake clutch system is operating properly.
Normal Test
Service Interval: Before each use or daily
1. Stop the engine and wait for all moving parts to
stop.
2. Move the lawn mower onto a paved surface in a
non-windy area.
3. Set all 4 wheels in to the 2-1/2 inches (64 mm)
cutting height setting (Figure 19).
