Std., K1585-1 Opt.): 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 pro-
tection system will stop the engine. Check for prop-
er 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 engine not running.

6. ENGINE ALTERNATOR AMMETER AND LIGHT

(K1585-2 Std., K1585-1 Opt.): The yellow engine
alternator light is off when battery 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 alternator, regulator, or the cooling blower
belt.

7. IDLER SWITCH: The 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 operates as fol-

lows:

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 (approxi-
mately 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 approxi-
mately 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.

IDLER OPERATIONAL EXCEPTIONS

When the WELDING TERMINALS switch is in the
“WELDING TERMINALS REMOTELY CONTROLLED”
position the idler will operate as follows:

a. When the triggering device (Amptrol, Arc Start

Switch, etc.) is pressed, the engine will acceler-
ate and operate at full speed provided a welding
load is applied within approximately 12 seconds.

b. If the triggering device remains pressed but no

welding load is applied within approximately 12
seconds, the engine will return to low idle speed.

c. If the triggering device is released or welding

ceases, the engine will return to low idle speed
after approximately 12 seconds.

8. HOUR METER: The hour meter displays the total

time that the engine has been running. This meter
is a useful indicator for scheduling preventative
maintenance.

WELDER CONTROLS (Items 9 through
14)

9. OUTPUT RANGE SELECTOR SWITCH & OUT-

PUT CONTROL: These two controls allow you to
select between various welding output slopes and
adjust the desired welding output. Refer to Table
B.1 for a description of how these two controls work.
