WARNING
Vehicle operation in hot weather can increase the risk of heat stress to crew members. Follow
individual preventive medicine measures in FM 21--11 to reduce the risk of heat stress in
armored vehicles.
GENERAL INFORMATION
The vehicle may overheat during long, hard towing operations in high gear or when driving at high speed. Check
temperature gauges and warning lights often. Stop vehicle to cool off whenever practical. Keep ventilating blower
on during operation. Inspect the air cleaners and oil coolers often. Clean off dust, insects, or debris from oil cool-
ers by brushing off screens or flushing with low pressure water. Have unit maintenance add tropical electrolyte to
batteries.
OPERATION OF HYDRAULIC SYSTEM
In hot weather and during continuous operation the hydraulic system may generate more heat than can be removed
by the hydraulic oil coolers with an engine speed of 1800 rpm. If the hydraulic reservoir temperature gauge reads
160° F or higher, increase the engine speed to 2000 rpm. If the MAX OIL TEMP EXCEEDED indicator comes on
(225° F (107°C)), see troubleshooting procedures.
VISION DEVICES
Check the periscopes for fungus growth on the lenses and clean if any is present. If paint is chipped, touch up im-
mediately to prevent rusting.
