CAUTION

POTENTIAL HAZARD

Excessive debris can cause the engine and hydraulic system to overheat.

WHAT CAN HAPPEN

Excessive debris around the engine cooling air intake and inside of the pump compartment can create a fire hazard.

HOW TO AVOID THE HAZARD

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.

4.1.3Check battery charge:

Service Interval: Monthly

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).
