Engine Speed

Battery Charging

1. Engine speed is factory set according to the speeds
listed in the Specifications section of this manual. Do
not tamper with the governor setting. The governor
establishes safe operating limits which must not be
exceeded.

2. Refer to the engine Owner’s Manual for procedure on
setting operating and idle speeds.

3. The engine operating speed should be set to 3600
RPM.

4. The engine idle speed must not exceed 1800 RPM. If
the idle speed is greater than 1800 RPM the clutch
may not disengage.

Battery Maintenance

1. The Odyssey battery is very different from standard
liquid-acid batteries that are openly vented.

2. The battery is, and operates as, a sealed battery,
recycling all gases internally. there is no corrosion to
the surrounding area.

3. The battery is shipped fully charged from the factory,
but prior to installation, check the battery’s voltage to
see if it is 12.65 volts or greater. If not, recharge it
using the procedure below. Caution: Never attempt

to remove the top decal cover, as it will cause the
battery to fail.

1. The state of charge in an Odyssey battery can be
determined from the following chart:

Voltmeter Reading State of Charge

12.84 Volts 100%

12.50 Volts 75%

12.18 Volts 50%

11.88 Volts 25%

2. To get a long life from the Odyssey battery, it is
important that the battery is kept near full charge,
approximately 12.8 volts.

3. If there are electrical loads during storage, then the
negative battery cable should be disconnected or a
Battery Tender trickle charge used. Low power 1.25
amp Battery Tenders will keep a fully charged battery
fully charged but cannot recharge if the battery
becomes discharged.

4. If a standard automotive charger is used to boost
charge a discharged battery it is important to make
sure the charging voltage does not exceed 15 volts
during charge. A hand held voltmeter can be used to
monitor this periodically. The following chart provides
recharge times under this type of boost charging to
an 80-95% recharge.

ODYSSEY Charge time for 100% discharged battery (11.5 volts)

Model 10-amp charger 20-amp charger

PC 925 2 1/2 hours 1 1/4 hours

Belt Adjustment

If any belt stretch develops follow these steps:

Refer to MAIN ASSEMBLY, page 22.

1. Remove the belt guard, refer to engine assembly
pages.

2. Loosen (do not remove) the four hex head
capscrews securing the engine deck to the
baseplate.

3. Tighten the belt by lifting the engine deck to provide
3/8 - 3/4 inch of “play” on one side of the belt. Be

sure to keep the engine deck level with the
baseplate when adjusting the belt.

4. Retighten the four hex head capscrews.

5. Reinstall the beltguard.
