HYDRAULIC PUMP DESTROKE BUTTON

DANGER

Depressing the pump destroke button while operating the machine will cause an immediate loss of hydraulic power, possibly creating a very dangerous situation. Hydraulic functions that will be affected are: FORK TILT, LIFT, BOOM EXTEND and RETRACT, PARKING BRAKE and SWAY. None of these functions will operate as long as the button is depressed. The service brakes will continue to function if the accumulator backup has a sufficient gas charge.

The pump destroke button (C) is the black push button switch located on the dash panel.

For example, when starting the machine for the first time on a 30 degree F. day, depress the pump destroke button while starting the engine. Continue to depress the button for 15 to 20 seconds after the engine starts. Once the engine is running smoothly, release the button and the hydraulic pump will engage. Depressing the pump destroke button will not be required for all other starts of the day, unless the engine has been allowed to cool completely.
