BATTERY MAINTENANCE
WARNING
GASES FROM BATTERY can explode.
• Keep sparks, flame, and cigarettes away from battery.
To prevent EXPLOSION when:
•INSTALLING A NEW BATTERY - Disconnect the negative cable from the old battery first and connect to the new battery last.
•CONNECTING A BATTERY CHARGER - Remove the battery from the welder by disconnecting the negative cable first, then the positive cable and battery clamp. When reinstalling, connect the negative cable last. Keep the area well ventilated.
•USING A BOOSTER - Connect the positive lead to the battery first, then connect the negative lead to the engine foot.
BATTERY ACID CAN BURN EYES AND SKIN.
•Wear gloves and eye protection and be careful when working near a battery. Follow the instructions printed on the battery.
CLEANING THE BATTERY
Keep the battery clean by wiping it with a damp cloth when dirty. If the terminals appear corroded, discon- nect the battery cables and wash the terminals with an ammonia solution or a solution of 1/4 pound (0.113 kg) of baking soda and 1 quart (0.946 l) of water. Be sure the battery vent plugs (if equipped) are tight so that none of the solution enters the cells.
After cleaning, flush the outside of the battery, the bat- tery compartment, and surrounding areas with clear water. Coat the battery terminals lightly with petrole- um jelly or a
Keep the battery clean and dry. Moisture accumula- tion on the battery can lead to more rapid discharge and early battery failure.
CHECKING ELECTROLYTE LEVEL
If battery cells are low, fill them to the neck of the filler hole with distilled water and recharge. If one cell is low, check for leaks.
The battery is a group 45, 495 amps cold cranking.
CHARGING THE BATTERY
When you charge, jump, replace, or otherwise connect battery cables to the battery, be sure the polarity is correct. Improper polarity can damage the charging circuit. The RANGER
If you need to charge the battery with an external charger, disconnect the negative cable first, then the positive cable before you attach the charger leads. After the battery is charged, reconnect the positive battery cable first and the negative cable last. Failure to do so can result in damage to the internal charger components.
Follow the instructions of the battery charger manu- facturer for proper charger settings and charging time.
WELDER/GENERATOR
MAINTENANCE
STORAGE: Store the RANGER
CLEANING: Blow out the generator and controls peri- odically with low pressure air. Do this at least once a week in particularly dirty areas.
BRUSH REMOVAL AND REPLACEMENT: It’s normal for the brushes and slip rings to wear and darken slightly. Inspect the brushes when a generator over- haul is necessary. Remove the brushes and clean the slip rings with fine emery paper. Refer to the “Brush Removal and Replacement” procedure in the Trouble- shooting and Repair section of this manual.
CAUTION
Do not attempt to polish slip rings while the engine is running.
