ENGINE CONTROLS (Items 1 through 8)
1. RUN/STOP
SWITCH
When placed in the RUN position, this switch energizes
the fuel solenoid and other electric accessories. When
placed in the STOP position, the flow of fuel to the
injection pump is stopped to shut down the engine.
NOTE: If the switch is left in the RUN position and the
engine is not running, the fuel solenoid will be engaged
for 15 seconds and then shut down. This is to protect
the battery from discharge. After 15 seconds, the
RUN/STOP switch must be toggled off then on before
starting.
2. START PUSHBUTTON
Energizes the starter motor to crank the engine. With
the engine RUN/STOP switch in the RUN position,
push and hold the Start button to crank the engine;
release as the engine starts. The Start button must be
depressed for a minimum of two seconds. Do not
press it while the engine is running, since this can
cause damage to the ring gear and/or starter motor.
3. FUEL LEVEL GAUGE AND LIGHT
(K1639-2 only) - Displays the level of diesel fuel in the
25-gallon (94.6 liter) fuel tank. The yellow light turns on
when the fuel gage reaches the reserve level. Once the
reserve level is reached, the engine protection system
will shut down the engine after 30 minutes of operation.
The machine can be restarted and operated for an
additional 30 minutes before the protection system will
shut down the engine. This ability to override the
engine protection allows the operator to “finish up” if
necessary. The operator must watch the fuel level
closely to prevent running out of fuel and having to
bleed the system.
4. ENGINE TEMPERATURE GAUGE (K1639-2
Std., K1639-1 Opt.) AND LIGHT
The gauge displays the engine oil temperature. The
yellow temperature light remains off under normal
operating temperatures. If the light turns on, the engine
protection system will shut down the engine. Check for
restrictions at the engine cooling air inlets and outlets.
(Consult the engine Operator’s Manual.) Check for
loose or disconnected leads at the temperature sender
located on the engine. Check the engine cooling blow-
er belt. Also, check to be sure that the welder loads are
within the rating of the welder. The light will remain on
when the engine has been shut down due to an over-
temperature condition.
5. OIL PRESSURE GAUGE (K1639-2 Std.,
K1639-1 Opt.) AND LIGHT
The gauge displays the engine oil pressure when the
engine is running. The yellow oil pressure light remains
off with proper oil pressure. If the light turns on, the
engine protection system will stop the engine. Check
for proper oil level and add oil if necessary. Check for
loose or disconnected leads at the oil pressure sender
located on the engine. The light will go on and stay on
when the RUN/STOP switch is switched to the RUN
position with the engine not running.
6. ENGINE ALTERNATOR AMMETER
(K1639-2 Std., K1639-1 Opt.) AND LIGHT
The yellow engine alternator light is off when the bat-
tery charging system is functioning normally. If the light
turns on, the engine protection system will shut down
the engine. Check the engine cooling blower belt. Also,
the alternator or the voltage regulator may not be oper-
ating correctly. The light may also come on due to a
faulty flashing circuit. The light will remain on when the
engine has been shut down due to a fault in the alter-
nator, regulator, or the cooling blower belt.
7. IDLER SWITCH
Has two positions as follows:
A) In the HIGH position , the engine runs at the
high idle speed controlled by the governor.
B) In the AUTO
/ position, the idler oper-
ates as follows:
a.
When switched from HIGH to AUTO or after
starting the engine, the engine will operate at
full speed for approximately 12 seconds and
then go to low idle speed.
b.
When the electrode touches the work or power
is drawn for lights or tools (approximately 100
Watts minimum) the engine accelerates and
operates at full speed.
c.
When welding ceases or the AC power load is
turned off, a fixed time delay of approximately
12 seconds starts.
d.
If the welding or AC power load is not restarted
before the end of the time delay, the idler
reduces the engine speed to low idle speed.
e.
The engine will automatically return to high idle
speed when the welding load or AC power load
is reapplied.
