SLAVE STARTING MACHINE CONTINUED
Ensure all non-essential systems on both machines are switched OFF.
Turn battery disconnect switch to the ON position (WP 0004) (also ensure that the battery disconnect switch on the dead
machine is also in the ON position), start engine of the slave (assisting) machine, and set the engine speed to 1,800 rpm
(see slave machine operator s manual).
Start engine of the dead machine using normal or cold start procedures as appropriate (WP 0005 or WP 0006).
Do not crank the engine longer than 30 seconds. Allow the starter to cool for 2 minutes before
cranking again. Failure to do so could result in damage to the alternator.
When engine starts, set the engine speeds of both machines to idle (see slave machine operator s manual) before discon-
necting NATO slave cable. Do not turn OFF the battery disconnect switch on either machine.
Disconnect NATO slave cable from assisted machine first and then from the slave machine. Secure protective caps (Fig-
ure 1, Item 1) on both machines.
10. Ensure engine is operating properly (WP 0004). If not, notify Field Maintenance.
11. If the assisted machine is not to be driven for 30 minutes, idle engine at 1,000 to 1,200 rpm for 30 minutes to recharge bat-
END OF TASK
EXTREME COLD WEATHER OPERATION +32 TO -25F (0 TO -31C)
Extreme cold weather causes oil to thicken, insulation to crack, materials to become brittle and break, and engine coolant and
batteries to freeze. Because of these and other problems, the machine will be more difficult to operate. Refer to and study the
information in FM 31-70, FM 31-71, FM 90-6, and FM 9-207. This information is necessary for effective operation of the
machine during extreme cold weather.
The following precautions will make for easier starting and prevent possible damage to your machine:
1. Ensure the engine has been filled with the correct viscosity oil (WP 0017).
Ensure the correct coolant mixture has been added to the engine cooling system (WP 0017).
Keep the batteries fully charged.
Fill the fuel tank at the end of each work period. This will help to prevent condensation forming on the tank walls.
Protect your machine when not in use.
Special care in cleaning and lubricating the machine must be taken where extremes in temperature, humidity, and terrain
exist. Good care of the machine ensures proper operation and functioning, it also guards against excessive wear of the
working parts and the deterioration of the material. Approved storage and handling instructions for lubricants and fuels
should be followed.
Refer to WP 0017 for lubrication instructions. These services should be done often during extremely cold and hot weather,
prolonged travel periods, fording, continued exposure to wet or salty air, operation in sand, dust, mud or for short stop/
start operation periods. Any of these conditions may reduce the effectiveness of the lubricants.
When repeated failure of the material results from exposure to extreme conditions, report the problem on DA Form 2404
and notify Field Maintenance.
