How to Adjust the Joystick
Max-out Setting
The max-out setting of a joystick controls the
maximum speed of a joystick-controlled machine
function. Whenever a hydraulic cylinder, drive
motor or hydraulic pump is replaced, the max-out
setting should be adjusted to maintain optimum
performance. The max-out settings on the joystick
can be changed to compensate for hydraulic
pump wear to maintain peak performance from the
machine.
Note: Perform this procedure with the boom in the
stowed position.

on position at both the ground and platform
controls.

that needs to be adjusted. Record the time it
takes for that function to complete a full cycle
(ie; boom up).

function times listed in Refer to Specifications,
Performance Specifications. Determine
whether the function time needs to increase or
decrease.
11 While the joystick is activated, adjust the
max-out setting to achieve the proper function
cycle time. Momentarily move the drive enable
toggle switch in the right direction to increase
the function speed or momentarily move the
drive enable toggle switch in the left direction to
decrease the function speed.
Note: Each time the drive enable toggle switch
is momentarily moved, the function speed will
change in 2% increments from a default of 100%,
with a minimum of 60% and a maximum of 120%.
12 Repeat steps 9 through 11 for each joystick
controlled machine function.
13 Return the joystick to the neutral position and
wait for approximately 10 seconds to allow the
