ENGINE AR-PRIMARY 4614662 - Caterpillar

Personal injury or death can result from a work tool falling.Keep personnel away from the front of the machine when lowering the work tool.
Before lowering any equipment with the engine stopped, clear the area around the equipment of all personnel. The procedure will vary with the type of equipment that is lowered. Keep in mind that most systems use a high-pressure fluid or air in order to raise or lower the equipment. The procedure will cause high-pressure air, hydraulic fluid, or some other media to be released in order to lower the equipment. Wear appropriate personal protective equipment and follow the established procedure in the Operation and Maintenance Manual, "Equipment Lowering with Engine Stopped" in the Operation Section of the manual.Lowering the Equipment with the Accumulator Charged
If electrical power is available and the accumulator is charged, the loader arms can be lowered from the operator station with the work tool control.
Fasten the seat belt. Lower the armrests.
Move the engine start switch to the ON position. Press the parking brake switch and release the parking brake switch. Note: The parking brake indicator will remain illuminated since the engine is not running. When the indicator for the work tool is no longer illuminated, the pressure can be released.
Slowly move the work tool control to the LOWER position in order to slowly lower the loader arms. If the loader arms do not lower, the accumulator is not charged. It is possible to recharge the accumulator by cranking the engine for 15 seconds. Repeat step 2 and 3.If there is no electrical power the loader arms must be lowered by using the procedure that is explained next.Alternate Lowering the Equipment
Personal injury can result from oil under high pressure.DO NOT allow high pressure oil to contact skin.Wear appropriate protective equipment while working with high pressure oil systems.
The loader arms must be lowered manually if the accumulator is not charged or if there is no electrical power.Do not go under the raised lift arm without the brace for the loader lift arm in the LOCKED position.Note: Make sure that there are no people near the front or sides of the machine.
