clockwise to raise the mower deck and counterclockwise
to lower it. If the crank is difficult to turn, thoroughly
clean and lubricate it.

BRAKE ADJUSTMENT
1. Stop the unit, turn the ignition OFF, set the ground
speed levers to PARK positions, and wait for all mov-
ing parts to stop.
2. Locate the brake rod (A) and adjustment nut (B).
4. Measure the parking brake spring. Its compressed
length, with the ground speed levers in their PARK
positions should be 3" (7.62cm). Adjust the spring
length by turning the adjustment nut (B), if necessary.
BATTERY CHARGING
WARNING
Keep open flames and sparks away from the
battery; the gasses coming from it are highly
explosive. Ventilate the battery well during
charging.
A dead battery or one too weak to start the engine may
be the result of a defect in the charging system or other
electrical component. If there is any doubt about the
cause of the problem, contact a Sears Parts & Repair
Center. If you need to replace the battery, follow the
steps under Cleaning the Battery & Cables in the
Regular Maintenance Section.
To charge the battery, follow the instructions provided by
the battery charger manufacturer as well as all warnings
included in the safety rules sections of this book. Charge
the battery until fully charged (until the specific gravity of
the electrolyte is 1.250 or higher and the electrolyte tem-
perature is at least 60 ° F). Do not charge at a rate higher
than 10 amps.
ENGINE ADJUSTMENTS
The engine is designed to deliver the correct perform-
ance under all operating conditions. Any adjustments
must be performed by a Sears or other qualified service
dealer.
