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.
STOPPING THE ENGINE
Remove all welding and auxiliary power loads and
allow engine to run at low idle speed for a few minutes
to cool the engine.
Stop the engine by placing the
“
Engine
”
switch in the
“
OFF
”
position.
A fuel shut off valve is not required on the Ranger 9
because the fuel tank is mounted below the engine.
BREAK-IN PERIOD
It is normal for any engine to use a greater amount of
oil until the break-in is accomplished. Check the oil
level twice a day during the break-in period (approxi-
mately 50 running hours).
IMPORTANT: IN ORDER TO ACCOMPLISH THIS
BREAK-IN, THE UNIT SHOULD BE SUBJECTED
TO MODERATE LOADS, WITHIN THE RATING OF
THE MACHINE. AVOID LONG IDLE RUNNING
PERIODS. REMOVE LOADS AND ALLOW ENGINE
TO COOL BEFORE SHUTDOWN.
The engine manufacturer
’
s recommendation for the
running time until the first oil change is as follows:
*
Change filter at first oil change.
**
The oil filter is to be changed at the second oil
change.
Refer to the Engine Owner
’
s Manual for more informa-
tion.

OPERATION
B-4
RANGER 9
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 trig-
ger 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:
•
WELDING
When the electrode touches the work, the welding arc
is initiated and the engine accelerates to full speed.
After welding ceases (and no auxiliary power is being
drawn), the engine will return to low idle after approxi-
mately 10 to 14 seconds.
•
AUXILIARY POWER
With the engine running at low idle and auxiliary power
for lights or tools is drawn (approximately100-150
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 sec-
onds, the idler reduces the engine speed to low idle.
STARTING/SHUTDOWN Instructions
