a.
General.
Operation
in
extreme
cold
temperatures creates special problems which require
careful inspection and maintenance. Personnel should
be especially careful not to subject the fire truck to any
sudden shocks, loads or rough handling which might
strain the equipment and crack or break metal parts. Do
not allow water to spray over the body of the truck or the
compartment doors' will freeze shut. All operations
must be started carefully at slow speeds. AH controls,
linkage, frame mountings, and drive parts must be
carefully inspected for damage. Refer to TM 9-
2320209-10 for additional information on operating the
fire truck in extremely cold temperatures.
b.
Lubrication. Be sure to use the correct grade of
lubricant for all points of application. Refer to LO 9-
2320-235-12 and LO 5-4210-213-12 for special cold
weather lubrication instructions.
c.
Hose Nozzle and Hoses.
If the hose nozzles
