CHECKING/SERVICING

CHECKING/SERVICING

DANGER

To prevent accidental starting of the engine when servicing or adjusting the ma- chine, remove the key from the ignition switch and disconnect the spark plug wire.

Security of Air Filtration Components

NOTE: The following inspection is only an external inspection and should be done without “disturb- ing” the filtration components.

On a daily basis, visually inspect the external condition of the complete air cleaner system. The following items should be inspected:

1.Check the Donaldson Radialseal™ air cleaner canister for damage. Make sure the cover is in place and the cover latches are secure - do not run the engine without the air cleaner cover in place and secure.

2.Inspect the air intake hose for cracks, nicks, cuts, etc., and check the hose clamps for tightness.

Battery

NOTE: For initial battery service during setup, refer to Battery Service in Assembly Instructions.

IMPORTANT: Make sure battery is securely mounted in the frame. A loose battery may cause damage to the case resulting in acid leakage and severe damage to the machine. A hazard may be created by damage to critical working parts and safety systems.

Electrolyte Level

The battery electrolyte level should be checked after every 25 hours of operation. To check electrolyte level:

1.Remove battery cell filler caps.

2.Check the electrolyte level. If the level is below the bottom of the vent well, fill with drinking water to the bottom of the vent wells [1/4 to 1/2 in. (6 to 13 mm) above the plates].

3.Replace filler caps.

IMPORTANT: DO NOT overfill the battery. Electrolyte will overflow through the vent tube onto parts of the machine and WILL result in severe corrosion.

Cleaning the Terminals

If battery terminals are corroded, remove battery from the mower. Using a wire brush, remove corrosion with a solution of one part baking soda and four parts water. Rinse with clean water. Coat the terminals with petroleum jelly or terminal protector spray to retard further corrosion.

Charging the Battery

DANGER

BATTERIES PRODUCE EXPLOSIVE

GASES

•Charge the battery in a well-ventilated area, so that gases produced while charg- ing can dissipate.

•Keep sparks, flames, and smoking ma- terials away from the battery at all times.

•Make sure the battery cap vents are open (check manifold vent on each cap).

•Make sure the battery charger is un- plugged before connecting or discon- necting cables to the battery.
