B. Charging the Battery

7.8 DRIVE BELTS

Refer to the battery charger’s manual for specific instructions.

Under normal conditions the engine’s alternator will have no problem keeping a charge on the battery. If the battery has been completely discharged for a long period of time, the alternator may not be able to recharge the battery, and a battery charger will be required.

DO NOT charge a frozen battery. It may explode and cause injury. Let the battery warm before attaching a charger.

Whenever possible, remove the battery from the mower before charging and make sure the electrolyte covers the plates in all cells.

WARNING

BATTERIES PRODUCE EXPLOSIVE GASES. Charge the battery in a well ventilated space so gases produced while charging can dissipate.

Charging rates between 3 and 50 amperes are satisfactory if excessive gassing or spewing of electrolyte does not occur or the battery does not feel excessively hot (over 125°F). If spewing or gassing occurs or the temperature exceeds 125°F, the charging rate must be reduced or temporarily stopped to permit cooling.

All drive belts are spring loaded and self-tensioning, however after the first 2, 4, 8 and 10 hours of operation, the belts should be checked for proper alignment and wear. Thereafter, check the belts after every 40 hours of operation or weekly, whichever occurs first.

- NOTE -

If you experience frequent belt wear or breakage, see your authorized Scag service center for belt adjustment.

7.9 CUTTER BLADES

A. Blade Inspection

1.Remove the ignition key before servicing the blades.

2.Raise the mower deck to the highest position. Place the lanyard pin in the highest cutting height positon to prevent the cutter deck from falling.

WARNING

Always wear proper hand and eye protection when working with cutter blades.

3.Check the cutter blades for straightness. If the cutter blades appear bent, they will need to be replaced.

C. Jump Starting

1.The booster battery must be a 12 volt type. If a vehicle is used for jump starting, it must have a negative ground system.

2.When connecting the jumper cables, connect the positive cable to the positive battery post, then connect the negative cable to the negative battery post.

WARNING

Do not attempt to straighten a bent blade, and never weld a broken or cracked blade. Always replace it with a new blade to assure safety.

4.If a blade cutting edge is dull or nicked, it should be sharpened. Remove the blades for sharpening. See "Blade Replacement."

- NOTE -

Keep the blades sharp. Cutting with dull blades not only yields a poor mowing job, but slows the cutting speed of the mower and causes extra wear on the engine and the blade drive by pulling hard.
