When an accumulator has a charge, the hydraulic equipment is active. The accumulator may have a charge even if the engine is not running. When the accumulator is used to activate the hydraulic circuit, the charge should bleed off in less than one minute. Movement can occur under the following conditions:
- The ignition key is in the ON position.
- The hydraulic control console is in the LOWERED position.
- The work tool is not positioned on the ground.

Deactivation of the hydraulic controls does not prevent the blade, boom swing, or auxiliary circuit functions from moving under gravity or other external forces. Gravity or other external forces can move the blade, boom swing, or auxiliary circuit functions suddenly if a hydraulic control lever is moved. Personal injury or death may occur from sudden machine movement. |
- Park on a level surface. If it is necessary to park on a grade, chock the tracks.
