1. Park mower on a portion of
lawn which has not been recently
mowed.
2. Set the cutting height so the
mower cuts 1/3 of the grass height.
3. Start the engine.
4. Press the Operator Presence
Control down against the handle-
bar grip and push the Blade Drive
Control fully forward until it stays in
the engaged position.

the No. 1 setting.

A.
Look at the lawn just mowed.
The lawn should be cut up to
the point where the Operator
Presence Control was released.
So
Press the Operator Presence
Control against the handlebar
grip but DO NOT re-engage the
Blade Drive Control. Drive the
mower forward for several more
feet. Release the Operator
Presence Control and look at
the lawn. The grass should
NOT have been cut. This indi-
cates that the Operator Pres*
- ence Control has disengaged
the blade drive and stopped the
blades.
7. If the mower cuts the grass in
Step 6-B, the Operator Presence
Control is NOT disengaging the
blade drive. Immediately stop
the engine, disconnect the
spark plug wire, and move the
wire away from the spark plug.
8. Do not use the mower until the
Blade Brake Control System has
been inspected, adjusted or re-
paired by a Sears Service Center.
