OM2228 Safety - Section 22 Warnings and Cautions Page 22-7 A wheel motor oil level decal is attached to the gear cover on both the electric wheel motors. This decal stresses that the truck must be on a level surface and parked for 20 minutes prior to checking the oil level. This is necessary in order to get an accurate reading. This plate is located below the left-hand battery box. It identifies the emergency engine shutdown switch. This switch is spring-loaded to the OFF position. It must be held in the ON position until the engine stops. This plate is located on the battery equalizer box.
After the key switch is turned OFF, allow at least 90 seconds of time to pass before opening (disconnect- ing) the battery disconnect switch. This time period allows hydraulic pressure to be released from the steering accumulators. A warning plate is located above the hydraulic sys- tem (APU) quick disconnect fittings in front of the hydraulic tank. The plate provides instructions to the operator or technician for towing a disabled truck. This plate specifies the requirements for an auxiliary source of supply for hydraulic oil and the proper hook-up. Ensure the steering and brake systems are operating properly before towing the truck. This plate is located on the battery equalizer box.
When the battery disconnect lever is in the left-hand position, it disconnects power (opens the circuit) from the batteries to the truck. When the lever is in the right-hand position, it connects (closes the circuit) from the batteries to the truck.
