HYDRAULIC PUMP DESTROKE BUTTON
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.
