MAINTENANCE J. BATTERIES Perform complete battery service on a new ma- chine after the first 50 hours of engine operation. Then, check electrolyte (acid) every 50 hours and perform maintenance every 250 hours. WARNING 1. WEAR SAFETY CLOTHES, GOGGLES OR FACE SHIELD, GLOVES AND SAFETY SHOES WHEN WORKING WITH BATTERIES. 2. WORK IN A WELL VENTILATED AREA. 3. BATTERY ELECTROLYTE (ACID) IS CORROSIVE. IF IT COMES IN CONTACT WITH SKIN, EYES OR CLOTHING, FLUSH WITH LARGE AMOUNTS OF WATER AND SEEK IMMEDIATE MEDICAL ATTEN- TION. SEE FIGURE 4.32A. 4. BATTERY ELECTROLYTE (ACID) PRODUCES HY- DROGEN GAS THAT IS HIGHLY EXPLOSIVE.

DO NOT ALLOW NEAR SPARKS, FIRE OR FLAMES AND DO NOT SMOKE WHEN WORKING WITH BATTERIES. SEE FIGURE 4.32A. FIGURE 4.32A SK32004074 4 1. Open the battery access door. See Figure 4.32B. 2. Remove battery cell caps and visually inspect electrolyte (acid) level. Proper level is 10~15 mm (0.4” ~ 0.6”) above cell plates. See Figure 4.32C. 3. If necessary, fill each cell to proper level with DISTILLED WATER ONLY. 4. Remove cables from terminals and clean with hot water. Coat each terminal with a thin layer of petroleum jelly. Clean cables in the same manner and reinstall onto battery. FIGURE 4.32B 5. If cables are found to be in poor condition, re- place with new parts immediately.

NEGATIVE (-) CABLE ELECTROLYTE LEVEL 10 15MM (0.4" 0.6") WARNING CELL PLATES PREVENT BATTERY EXPLOSION • Batteries give off hydrogen gasses that can explode and cause personal injury. • Keep sparks, open flames and cigarettes away from batteries. • Keep metallic articles away from batteries. • Keep all ventilation caps tightly secured. • Never check charge by placing metal articles across battery terminals. • Leave battery box open to improve ventilation when charging.
