CUTTING HEIGHT ADJUSTMENT
Turn the cutting height adjustment crank (A, Figure 31)
clockwise to raise the mower deck and counterclockwise
to lower it. If the crank is difficult to turn, thoroughly
clean and lubricate it.
PTO CLUTCH ADJUSTMENT
See CHECK / ADJUST PTO CLUTCH in the
Maintenance Section.
BRAKE ADJUSTMENT
1. Lift up the seat deck.
2. Set the parking brake to DRIVE.
3. Push the brake lever (C, Figure 32) forward and pull
the brake rod (A) back. There should be an approxi-
mately 5/8" - 1/2" gap between the adjustment nut (B)
and brake lever. If not, adjust the nut (B) until 1/8" is
achieved.
4. Repeat on both sides.
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 carburetor is designed to deliver the correct fuel-to-
air mixture to the engine under all operating conditions.
The main fuel jet is calibrated at the factory and is not
adjustable. The low idle fuel adjusting needle is also set
at the factory and normally does not need adjustment.

To ensure proper operation at altitudes above 5000 feet,
it may be necessary to have an authorized Kohler dealer
install a special high-altitude jet kit in the carburetor. If a
high-altitude kit as been installed, the engine must be
converted back to the original jet size before it is operat-
ed at lower altitudes. If not, overheating and engine
damage can result.
