T-964C PART TWO - INSTRUCTIONS
c. SELF-STARTER - When the engine is equipped with a self-starter, turn the ig­
nition switch ON (turn key clockwise), and push'the starter pushbutton until the
engine fires. Use the choke if necessary.
CAUTION
DO NOT crank the engine longer than 30 seconds
at a time. If the engine does not start in 30
seconds, allow starter to cool for one minute
before attempting again to start the engine.
16. AFTER THE ENGINE STARTS
a. Check the oil pressure gauge on the left side of the engine block to make
certain it is registering properly. If it is not registering a steady pressure
within 30 seconds, stop the engine immediately and inspect the lubricating system
and the oil level in the crankcase.
b. Adjust the choke to a point where the engine runs without missing. As the
engine warms-up, the choke should be pushed in all the way. DO NOT use the choke to
enrich the fuel mixture, except when starting the engine. NEVER operate the engine,
after it reaches normal running temperature, with the choke partly closed.
c. Warm up the engine by running it for a few minutes at the idling speed. (900
rpm).
d. While the engine is warming up check the engine components for leaks and
loose connections.
17. STOPPING THE ENGINE
a. Disconnect the welding load.
b. Allow the engine to idle for a few minutes to cool valves and pistons.
c. Turn the ignition switch 'OFF'.
d. If engine oil is to be changed it can be done more effectively while the en­
gine is still warm.
18. OPERATION IN COLD WEATHER
a. GENERAL - Operation of engine driven welding units at sub-zero temperatures
requires special precautions and extra servicing from both operation and mainten­
ance personnel if poor performance or total funtional failure is to be avoided.
Equipment can be operated more satisfactorialy in extremely cold weather if the
following preparations are made.
b. FUEL SYSTEM - The complete fuel system should be cleaned to remove any water
that may have accumulated in the system. Care should be taken that there are no
pockets in the fuel lines in which water can collect and freeze, shutting off or re­
reducing the flow of fuel. Fuel tanks should be kept FULL to prevent water conden­
sation from the air above the fuel. Check the filter bowl daily as water may col­
lect here, freeze, and crack the bowl.
