It then quickly loses its elasticity and becomes brittle. Remember to use antifreeze in coolant systems. Quick heat is a technique that allows quick warmup and reliable starting when vehicle temperatures drop as low as the existing ambient temperature.
When buildings are not available, maintenance tents are a temporary expedient. Enter Your Email Address.
Batteries should be filled with 1. If possible, tents should have wood flooring and be heated by portable duct heaters or tent stoves. A tarpaulin should be placed under each vehicle to catch parts that may be dropped.
Special Considerations Before Operations Checks. The military objective is to achieve reliable starting within a maximum of one hour regardless of ambient temperature.
Operation & Maintenance of Ordnance in Cold Weather FM 9 207
Always consult the appropriate TM or lubrication order LO. Fuel carbonizes if the combustion chambers do not get hot enough. Lighting equipment must be available to furnish adequate illumination for maintenance services. If the vehicle does not have a preheater, an insulated battery box can help maintain specific gravity at higher levels for longer periods. When employed in a cold region, a force actually faces two enemies–the tactical enemy and the environment that also aggressively attacks and can destroy equipment and men.
Without some type of permanent or temporary shelter, even routine maintenance can become extremely difficult.
Operational Considerations Power Takeoff Assemblies. It is the responsibility of unit leaders to ensure that personnel and equipment can withstand the challenges of cold weather. Drive trains may have to be disconnected to prevent further damage.
Multioption fuzes should be selected whenever available to provide for seasonal changes. Glass, porcelain, and other ceramics perform normally at low temperatures if handled carefully. Special fuel and lubricants must also be used to prevent freezing and jelling. If cables are to be bent, they must first be warmed. However, soldiers and their leaders must understand the f of cold weather and adapt operations and maintenance to overcome environmental conditions.
9–207 canvas covers with plastic windows 9207 break due to a combination of cold and vibration. Soldiers must check battery charges using hydrometers and testers.
The present generation of power plant heaters are water coolant type, thermostatically controlled to heat the engine block and the water pillow below the batteries. Under such conditions, personnel are subject to decreased f, and cold casualties, equipment is prone to breakdowns, supply problems are increased, and operations are restricted and complicated by the environment.

Maintenance of mechanical equipment is exceptionally difficult in the field during cold weather. It uses no external power in the run cycle and needs only 6 amperes at 24 volts for starting. Complete winterization, diligent maintenance, and well-trained crews are the keys to reducing the adverse effects of cold weather.
This blockage 9-07 can lead to premature igniter failure due to excessive start attempts. The standby heat concept does not allow vehicle components to fall below a certain minimum temperature.
Antifreeze materials ffm for protection of liquid-cooling systems are listed in Appendix A. Read all caution plates and estimate a percent reduction in capacity when determining load.
