HOW TO PREPARE THE MACHINE FOR OPERATION

Battery Maintenance

The electrical power to operate the machine comes from the storage batteries. Storage batteries need preventative maintenance.

WARNING: Working with batteries can be dangerous.

Always wear eye protection and protective clothing when working near batteries. NO SMOKING!

To maintain the batteries in good condition, follow these instructions:

1. Keep the electrolyte at the correct level. The correct level is between 1/4” (1/2 cm) below the bottom of the tube in each cell and above the tops of the plates. Check the level of the electrolyte each time you charge the batteries. See ﬁ gure 6.

Correct Level

NOTE: Check the level of electrolyte prior to charging the batteries. Be sure the plates in each cell are covered with electrolyte before charging. Do not top off the cells prior to charging the battery. Electrolyte expands during charging. As a result, the electrolyte could overﬂ ow from the cells. Always top off the cells with distilled water after charging.

CAUTION: Irreversible damage will occur to the batteries if

electrolyte does not cover the plates. Keep the electrolyte at the correct level.

CAUTION: Machine damage and discharge across the tops of

the batteries can occur if the batteries are over ﬁ lled. Do not ﬁ ll the batteries up to the bottom of the tube in each cell. Wipe any acid from the machine or the tops of the batteries. Never add acid to a battery after installation.

CAUTION: Batteries must be reﬁ lled with distilled water only. Do

not use tap water as it may contain contaminants that will damage batteries.

2. Keep the tops of the batteries clean and dry. Keep the terminals and connectors clean. To clean the top of the batteries, use a damp cloth with a weak solution of ammonia or bicarbonate of soda solution. To clean the terminals and connectors, use a terminal and connector cleaning tool. Do not allow ammonia or bicarbonate of soda to get into batteries.

Figure 6

Figure 7

3. Keep the batteries charged.

4. To drain battery compartment: (See ﬁ gure 7)

a. Always wear protective eye protection and protective clothing. b. Add a weak solution of ammonia or bicarbonate of soda solution to

battery compartment to neutralize any spilled acid. c. Locate drain hose behind the transaxle. d. Place hand behind ﬂ ange and open valve. e. When empty, close valve. f. Neutralize any acid spills with ammonia or bicarbonate of soda.

EN

1. Make sure the key switch is in the “OFF” position.

2. Before charging the batteries, the battery compartment needs to be vented. To vent compartment, tip up the recovery tank and rotate the tank support bracket, located in the solution tank (see ﬁ gure 8). Slowly lower the recovery tank and let it rest on the support bracket (see ﬁ gure 9). To close the tank, lift up on the recovery tank, rotate the support bracket down, then slowly lower the tank to the closed position.

CAUTION: Before raising tank, be sure tank is empty.

W ARNING: Do not operate the machine while the recovery

tank is in the open position. The tank can be accidentally bumped and it may slam shut.

3. Connect the battery charger AC cord located at the rear of the machine to an appropriate wall receptacle.

4. Observe indicator lights on the charger/battery meter to ensure the charging process has started. Red, yellow and green lights indicate state of charge. Steady on green light indicates the batteries are fully charged.

Figure 8

Figure 9

NOTE: Make sure you plug into a circuit that is not loaded by other equipment. Wall breakers may be tripped and no charge will occur.

WARNING: Never charge any battery with an unsuitable

battery charger. Carefully follow the instructions given by the manufacturer of the batteries and battery charger.

NOTE: To prevent permanent damage to the batteries, avoid their complete discharge. Never leave the batteries completely discharged, even if the machine is not being used. When recharging the batteries, keep the recovery tank open. Check the level of the electrolyte and if necessary top off with distilled water.
