Caterpillar Skid Steer Loader 272D2

Warning: Personal injury can result from hydraulic oil pressure and hot oil. Hydraulic oil pressure can remain in the hydraulic system after the engine has been stopped. Serious injury can be caused if this pressure is not released before any service is done on the hydraulic system. Make sure all of the attachments have been lowered, oil is cool before removing any components or lines. Remove the oil filler cap only when the engine is stopped, and the filler cap is cool enough to touch with your bare hand.

Start the engine and allow the engine to run for at least 15 seconds to recharge the accumulator.

Stop the engine. Keep the armrests in the LOWERED position. Turn the engine start switch to the ON position. Push the parking brake switch.

Move the electrohydraulic controls through all the positions.

Toggle the auxiliary switch multiple times.

Turn the engine start switch to the OFF position. The pressure in the hydraulic system has now been released.

Note: Some hydraulic lines on the downstream side of the accumulator may still contain pressurized oil. Use caution when you disconnect these hydraulic lines.
