In each hydraulic control arrangement, there are
several electronic component parts that can be re-
placed if they are no longer working properly.
These components are:
• Direction Control Switch - The Direction
Control Switch (DCS) is an optional feature
and is used to select the direction of travel
when lift truck is equipped with a standard
accelerator pedal.
• Emergency Disconnect Switch - The
emergency disconnect switch is used to dis-
connect power from the controllers. The
switch is operated by pushing the button
down until it clicks. To reset (re-connect) the
emergency disconnect switch and energize
the electrical circuits, turn the switch clock-
wise until button pops up.
• Attachment (Fourth Function) Button -
The attachment button is only on manual hy-
draulic control levers. If lift truck is equipped
with a four function control valve with at-
tachment and three levers, the last (3rd)
lever controls the attachment (4th function).
To engage the attachment, press and hold
button on the left top side of the lever and
move lever forward. To disengage the attach-
ment press and hold button on the left top
side of the lever and move lever backward.
See Figure 13.
When removing and replacing sensors or switches,
be sure to tag connectors to aid in correct installa-
tion.
