OPERATION
BUDE BRAKE CONTROL
TEST
When the Operator Presence
Control is released during opera­
tion of the mower, the engine does
not stop, but the blades should
stop within three (3) seconds. The
following test provides a visual test
of whether the Blade Brake Control
System is functioning. Perform
this test before each use of the
mower.
WARNING
To avoid personal injury or
property damage, make sure
that the mower is on grass,
and that the test area is clear
of foreign objects and by­
standers before you begin the
Blade Brake Control Test.
f .TJ
It the Operator Presence Con­
trol or the Blade Drive Control
are not adjusted correctly, the
blades may continue to rotate
after release of the Operator
Presence
Control. If the
blades do not stop within
three (3) seconds of release
of the Operator Presence Con­
trol, move the Engine Throttle
Control to the STOP position,
disconnect the spark plug
wire, and move the wire away
from the spark plug. Do not
operate the mower until the
Blade Brake Control System
has been repaired.
Failure to do this could result
in personal injury or property
damage.
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 fonward until it stays in
the engaged position.
5. Put the Gear Select Lever in
the No. 1 setting.

Wheel Drive Control and drive the
mower for several feet. Then re­
lease the Operator Presence Con­

A. Look at the lawn just mowed.
The lawn should be cut up to
the point where the Operator
Presence Control was released.
B. Press the Operator Presence
Control against the handlebar
grip but DO NOT re-engage the
Blade Drive Control. Drive the
mower fonward 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
sparkplug 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.
