To insure safe operation of your unit, all nuts and bolts must be checked periodically for correct tightness.
MAINTENANCEOF BATTERY
1.Check electrolyte level periodically (at least every two weeks). Keep the level to the split rings. Use only distilled water or a good quality drinking water. Never add acid or any other chemicals to the bat- tery after initial activation.
2.The battery should be checked with a hydrometer after every 25 hours of operation. If the specific gravity is less than 1 .225, the battery should be recharged. For Model 704F, maximum charge rate 5 AMPS.
3.Coat the terminals and exposed wire with a thin coat of grease or petroleum jelly for longer service and protection against corrosion.
4.The battery should be kept clean. Any deposits of acid should be neutralized with soda and water. Be careful not to get this solution in the cells.
5.Avoid tipping the battery. Even a "sealed" battery will leak electrolyte when tipped.
STORAGEOF THE BATTERY
1.Charge battery using normal methods. NEVER store discharged battery as it will not recover.
2.When storing battery for extended periods, discon- nect battery cables. Removing battery from unit is recommended.
3.Store in cold, dry place.
4.Recharge battery whenever the specific gravity is less than 1.225, before returning to service, or every two months, whichever occurs first.
COMMONCAUSESFOR BATTERYFAILURE
1.Overcharging
2.Undercharging
3.Lack of water
4.Loose hold downs and/or corroded connections
5.Excessive loads
6.Battery electrolyte substitutes
7.Freezing of electrolyte
NOTE: These failures do not constitute warranty.
BATTERYREMOVALOR INSTAllATION
WARNING: When removing the battery, follow this order of disassembly to prevent your wrench from shorting against thefram
1.Remove the Negative cable.
2.Remove the Positive cable.
To install a battery:
1.Attach the Positive cable.
2.Attach the Negative cable.
JUMPSTARTING
1.Attach the first jumper cable from the Positive ter- minal of the good battery to the Positive terminal of the dead battery.
2.Attach the second jumper cable from the Negative terminal of the good battery to the FRAME OF THE UNIT WITH THE DEAD BATTERY.
AWARNING: Failure to use this starting pro- cedure could cause sparking, and the gases in either battery could explode.
TIRES
Recommended operating tire pressure is approximately 12 p.s.i. (check sidewall of tire for tire manufacturer's recommended pressure). Maximum tire pressure under any circumstances is 30 p.s.i. Equal tire pressure should be maintained on all tires.
When installing a tire to the rim, be certain rim is clean and free of rust. Lubricate both the tire and rimgen
Never inflate to over 30 p.s.i. to seat beads.
WARNING: Excessive pressure (over 30p.s. when seating beads may causetire/r assembly to burst with force suf-
ficient to cause serious injury.
DECKBELTREPLACEMENT
When replacing the deck belt, disconnect the spring from transaxle, inside the right rear wheel (step 5). Refer to the separate deck manual packed with your
unit.
DRIVE BELT REPLACEMENT
MODEL 704F (See Figure 22)
1.Depress the clutch pedal and set parking brake.
2.Remove the deck from the lawn tractor.
3.Raise and block the front wheels of the lawn trac- tor so you can work under it.
4.Remove the transmission panel, and unhook the spring from the rear idler pulley.
