5-2. COLD CONDITIONING.

The cold conditioning version of the truck differs from
SERIAL
the standard model where necessary to improve per-
formance in cold temperatures. Heating resistors are
provided for the control head switches, and cold resis-
tant versions of other switches and the hydraulic hoses
SERIAL
are used. Special cold temperature lubricants are also
necessary for this application.

truck is used or not. To avoid power
waste, disconnect battery of cold condi-

ods at temperatures low enough to
energize cold conditioning equipment
are planned.
