Service Interval: 40 hrs.
a) Make sure mower is on a level surface.
b) Stop engine, wait for all moving parts to stop.
c) Visually inspect the sight gauge on hydraulic tank. Oil level should be
visible to top of sight gauge. If not, clean area around hydraulic reservoir

Service Interval: 40 hrs.
a) Stop engine, wait for all moving parts to stop, and remove key.
b) Inflate tires to pressures specified in Section 2.8 (Specifications).
c) See Section 8.1 for further information.
NOTE: Do not add any type of tire liner or foam fill material to the tires.
Excessive loads created by foam filled tires may cause failures to the hydro drive
system, frame, and other components. Foam filling tires will void the warranty.
6.1.11 Check battery charge:
Service Interval: Monthly
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.
a) Check the voltage of the battery with a digital voltmeter. Locate the voltage
reading of the battery in the table below 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 cables are disconnected
and the battery charger used for charging the battery has an output of 16
volts and 7 amps or less to avoid damaging the battery (see chart below for
recommended charger settings).
