Dear Hi Ranger Owner,
REASON FOR NOTICE
Terex has become aware that some installers have installed XT Pro units, from July 17, 2014 through
December 30, 2015, with non-sealed electric switches external to the cab for outriggers, unit select and
chipbox circuits. These switches are not suitable for exterior applications where they can be exposed to
water as it can cause a short circuit. A short circuit in the switch(s) can result in the outriggers
extending, or the chip box to raise (if equipped), unintentionally only under the following
conditions:
• Outrigger Extending
o The outrigger switch has short circuited
o The PTO switch is on
o The selector switch is in not in “unit” mode.
o The parking brake is set.
• Rising Chip box
o Both the “Box Enable” and “Box Dump” switches have to short circuit
o The PTO switch is on
o The parking brake is set
WHAT TEREX UTILITIES WILL DO
Because Terex Utilities wants your product to perform as you would expect please respond to this
bulletin so Terex can repair all affected units. Terex will replace the non-sealed switches and harnesses
with new sealed switches and harnesses at no charge.
WHAT YOU SHOULD DO
Immediately inspect the switches shown and instructed on the attached bulletin PN637. If non-sealed
switches are present follow continued use instructions below. Within 60 days from receiving this notice
contact your local Terex Utilities dealer, or contact the Terex Utilities Service Department at 1-800-9828975, or email the machine information to [email protected], to schedule an appointment to
have repairs performed.
CONTINUED USE:
Always follow all maintenance and inspection requirements as specified in the manuals. All machine
users and operators should be notified of these continued use requirements. If non-sealed switches are
installed on the unit you may continue to use the unit, until repairs are made, provided:
1. As soon as the unit is leveled with the outriggers, move the selector switch to the “UNIT”
position. Keep the switch in this position anytime the boom is elevated or occupied.
2. Turn the master switch for the PTO off any time the unit is not in use, including during breaks
and travel. Do not depend on the parking brake interlock to disable the system.
3. Avoid exposing these switches to water.

Reconnect when its required to dump chips.
