Service Interval: Daily or more often in dry conditions
POTENTIAL HAZARD
♦ Excessive debris can cause the engine
WHAT CAN HAPPEN
♦ Excessive debris around the engine
HOW TO AVOID THE HAZARD
♦ Clean all debris from around the engine
a) Stop engine, wait for all moving parts to stop, and remove key. Engage
parking brake.
b) Clean all debris from rotating engine air intake screen and from around
engine shrouding.
4.1.3 Check battery charge:
Allowing batteries to stand for an extended period 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).
