Starting/Shutdown Instructions
Starting the Engine
Be sure all Pre-Operation Maintenance has been per-
formed. Also, read the Engine Owner’s Manual.
Remove all loads connected to the AC power recepta-
cles. To start the engine, set the “Idler Control” switch
in the Automatic ( / ) position.
Use the choke control as follows:
Onan Engine - If the engine is cold, pull the choke
control out. Do not use the choke if the engine is warm
or hot.
Kohler Engine - Always pull the choke control out
when starting the engine; cold, warm or hot. Place the
“Engine” switch in the “ON” position.
Push the “START” button and crank the engine until it
starts. Release the button as soon as the engine
starts. Do not push the “START” button while the
engine is running because this will cause damage to
the ring gear and/or starter motor. After the engine
has started, slowly return the choke control to the full
“in” position (choke open).
After running at high engine speed for 10-14 seconds,
the engine will go to low idle.
Allow the engine to warm up by letting it run at low idle
for a few minutes.
“CONTROL AT WELDER /
The toggle switch on the control panel labeled
“CONTROL AT WELDER” and “REMOTE CONTROL
”
gives the operator the option of controlling the output
at the welder control panel or at a remote station.
Remote connections are made at the 6-pin or 14-pin
amphenol connector.
For remote control, the toggle switch is set in the
“REMOTE CONTROL” position.
For control at the welder control panel, the toggle
switch is set in the “CONTROL AT WELDER” position.
“WELDING TERMINALS” Switch
The toggle switch labeled “WELDING TERMINALS
ALWAYS ON” and “WELDING TERMINALS
REMOTELY CONTROLLED” is used to control the
operation of the welder output contactor.
With the switch in the “ALWAYS ON” position, the
output contactor is closed at LOW and HIGH idle.
With the switch in the “REMOTELY CONTROLLED”
position, the contactor is open at LOW idle and HIGH
idle until a control cable is attached to the welder
amphenol connector from a wire feeder. Under this
condition, contactor closes when the wire feeder
trigger is depressed and opens when the trigger is
released.
“IDLER” Switch
The idler switch has two positions, “HIGH” and
“AUTO”.
When in “HIGH” position, the engine will run
continuously at high idle.
When in “AUTO”
/ idle position, the idler
operates as follows:
a. Welding
Low idle and in the “WELDING TERMINALS ALWAYS ON” mode -
Stick Welding only.
When the electrode touches work, the
welding arc is initiated and the engine accelerates to
full speed.
Low idle and in the “WELDING TERMINALS REMOTELY
CONTROLLED” mode -Wire Welding Only
Pressing the gun
trigger closes the Ranger 9 output contactor and
causes the engine to accelerate to full speed.
After the gun trigger is released and/or welding
ceases (and no auxiliary power is being drawn), the
engine will return to low idle after approximately 10 to
14 seconds.
REMOTE CONTROL” Switch
-16 -
b. Auxiliary Power - With the engine running at low
idle and auxiliary power for lights or tools is drawn
(approximately 100-150 watts or greater) from the
receptacles, the engine will accelerate to high speed.
If no power is being drawn from the receptacles (and
not welding) for 10-14 seconds, the idler reduces the
engine speed to low idle.
• Do not touch electrically live parts
of electrode with skin or wet
clothing.
• Keep flammable material away.
• Insulate yourself from work and
ground. Wear eye, ear, and body
protection.
• Keep your head out of the fumes.
• Use ventilation or exhaust to
remove fumes from breathing zone.
