E-HYDRAULIC CONTROLS
The lift trucks covered in this service manual may
be equipped with optional E-Hydraulic control
mini-levers. See Figure 14. Each mini-lever can be
replaced separately if one malfunctions. Like man-
ual control levers, E-Hydraulic control mini-levers
can be equipped with an optional attachment func-
tion (either the third or fourth mini-lever). There is
a momentary switch behind the mini-lever (either
the third or fourth mini-lever) that engages and
disengages the attachment function. If attachment
function quits working, mini-lever and momentary
switch may need to be replaced. See sections Mini-
levers, Remove and Install and Momentary
Switches and Function Selection Button for re-
placement procedures.
Mini-levers, Remove and Install
CAUTION
The following procedure should only be per-
formed by Hyster trained certified technicians.
The removal and replacement of the mini-levers
should be done in a clean environment whenever
possible and on an electrically grounded surface.
DO NOT touch any printed circuit board (PCB)
surface to prevent damage from electrostatic volt-
age.
