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 wires.
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 Cummins/Fleetguard OptiAir™ air cleaner canister for damage. Make sure the cover is in place and the cover latch is 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.
3.Check to make sure the air flow indicator is in place and tight.
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.
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
•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.
Check the battery charge by measuring the specific gravity of electrolyte; if specific gravity is less than 1.225, the battery will need to be charged as follows:
•Charge the battery at 15 amps for 10 minutes. DO NOT exceed 20 amps maximum recommended charging rate. Charge until specific gravity is at least 1.250. Total charging time should not exceed one (1) hour.
Tire Pressure
Inflate tires to pressures shown below:
Deck Caster Wheel = 20 PSI (137 kPa)
Drive | = | 15 PSI (103 kPa) |
Rear | = | 20 PSI (137 kPa) |
Wheel Nuts Torque
Check every 100 hours the eight (8) Drive Tire mounting nuts. They should each be torqued to
Sharpen Mower Blades
Check mower blade(s) for straightness, sharp- ness, condition of the cutting edge, and balance every 10 hours of operation (or more often when mowing abrasive type grass or operating on sandy soils). Replace blades if worn, bent, cracked, or otherwise damaged (refer to REPLACING/ REPAIRING the Mower Blades in this section). Use the following procedure to check and sharpen blades:
