Case Wheel Loader 621D Repair Manual

SAMPLE PAGE OF THE MANUAL:

• If damage causes an electrolyte leak, replace the battery. Inspect the battery at regular intervals for dirt, corrosion, and damage. Electrolyte and dirt on the top of the battery can cause the battery to discharge by making a passage for the current to flow. If the battery must be cleaned, remove the battery from the battery carrier and clean the battery, cable terminals, and the battery carrier.
• When available, use Case Battery Saver and Cleaner according to the instructions on the container. Case Battery Saver and Cleaner also helps prevent corrosion. If Case Battery Saver and Cleaner is not available, use baking soda and water as a cleaner. DO NOT permit any type of cleaner to enter the cells of the battery.
• Install the battery in the machine and make sure the fasteners are tight. Apply Case Battery Saver and Cleaner or Urethane Seal Coat to the cable terminals to prevent corrosion. See the Parts Counter Catalog. DO NOT apply grease.
• Information will be displayed in different zones on the LCD, as directed by the operator or machine. In most situations the operator or technician will be given specific information to follow if conditions are not correct.
• In the example above the machine hours are displayed. Machine hours will always be displayed briefly on start up. After the machine is started the display will show engine rpm’s. After beginning travel the machine will display travel speed provided default settings were not changed by the operator.
• The power mode allows the operator to choose the most effective machine power for the current job conditions. Most commonly auto is chosen, as the power will automatically increase or decrease between maximum power and standard power while the machine is working.
• This allows for maximum power if necessary, but will switch to standard mode for economy. Maximum power can be chosen for more severe work conditions. Economy can be chosen for limited power and fuel efficiency. Press and hold the confirmation button for two seconds to arrive at the service screen.
