Periodic Maintenance
Check Engine Oil Level
Service Interval: Before each use or daily
1. Stop engine and wait for all moving parts to stop.
Make sure unit is on a level surface.
2. Check with engine cold.
3. Clean area around dipstick. Remove dipstick
and wipe oil off. Reinsert the dipstick according
to the engine manufacturer's recommendations.
Remove the dipstick and read the oil level.
4. If the oil level is low, wipe off the area around the
oil fill cap, remove cap and fill to the “FULL”
mark on the dipstick. Exmark 4-Cycle Premium
Engine Oil is recommended; refer to the Engine
Owner's manual for an acceptable alternative. Do
Not overfill.
Important: Do Not operate the engine with the
oil level below the “LOW” (or “ADD”) mark on
the dipstick, or over the “FULL” mark.
Check Battery Charge
Service Interval: As required
WARNING
CALIFORNIA
Proposition 65 Warning
Battery posts, terminals, and related
accessories contain lead and lead
compounds, chemicals known to the State of
California to cause cancer and reproductive
harm. Wash hands after handling.
Allowing batteries to stand for an extended period of
time without recharging them will result in reduced
performance and service life. To preserve optimum
battery performance and life, recharge batteries in
storage when the open circuit voltage drops to 12.4
volts.
Note: To prevent damage due to freezing, battery
should be fully charged before putting away for
winter storage.
Check the voltage of the battery with a digital
voltmeter or with the message display. If the ignition
key is turned to the “on” position for a few seconds,
the battery voltage will be displayed in the area where
the hours are normally displayed. Locate the voltage
reading of the battery in the table and charge the
battery for the recommended time interval to bring
the charge up to a full charge of 12.6 volts or greater.
Important: Make sure the negative battery cable
is disconnected and the battery charger used for
charging the battery should have an output of
16 volts and 7 amps or less to avoid damaging
the battery (see chart for recommended charger
settings). This is especially important on Kohler
EFI (Electronic Fuel Injection) units. Failure to
do so may damage the ECU (Electronic Control
Unit).
