SAFETY PRECAUTIONS
WARNING
Do not attempt to use this equipment until you have
thoroughly read the engine manufacturer's manual supplied
with your welder. It includes important safety precautions,
detailed engine starting, operating and maintenance
instructions, and parts lists.
ELECTRIC SHOCK can kill.
•
Do not touch electrically live parts or
electrode with skin or wet clothing.
•
Insulate yourself from work and ground
•
Always wear dry insulating gloves.
ENGINE EXHAUST can kill.
•
Use in open, well ventilated areas or
vent exhaust outside.
MOVING PARTS can injure.
Do not operate with doors
•
open or guards off.
Stop engine before servicing.
•
Keep away from moving parts.
•
See additional warning information at front of
this operator's manual.
Only qualified personnel should install, use, or
service this equipment.
VRD (VOLTAGE REDUCTION DEVICE)
The VRD feature provides additional safety in the CC-Stick mode
especially in an environment with a higher risk of electric shock
such as wet areas and hot humid sweaty conditions.
The VRD reduces the OCV (Open Circuit Voltage) at the welding
output terminals while not welding to less than 30V DC when the
resistance of the output circuit is above 200 (ohms).
The VRD requires that the welding cable connections be kept in
good electrical condition because poor connections will contribute
to poor starting. Having good electrical connections also limits the
possibility of other safety issues such as heat-generated damage,
burns and fires.
The machine is shipped with the VRD switch in the "Off" position.
To turn it "On" or "Off":
• Turn the engine "Off".
• Disconnect the negative battery cable.
• Lower the control panel by removing 4 front panel screws.
(See Figure A.1)
• Place the VRD switch in the "On or "Off" position. (See Figure
A.1)
With the VRD switch in the "On" position, the VRD lights are
enabled.
LOCATION AND VENTILATION
The welder should be located to provide an unrestricted flow of
clean, cool air to the cooling air inlets and to avoid restricting the
cooling air outlets. Also, locate the welder so that the engine
exhaust fumes are properly vented to an outside area.

CAUTION
DO NOT MOUNT OVER COMBUSTIBLE
SURFACES
Where there is a combustible surface directly under
stationary or fixed electrical equipment, that surface should
be covered with a steel plate at least .06"(1.6mm) thick,
which should extend not less than 5.90"(150mm) beyond the
equipment on all sides.
STORING
1. Store the machine in a cool, dry place when it is not in use.
Protect it from dust and dirt. Keep it where it can't be
accidentally damaged from construction activities, moving
vehicles, and other hazards.
2. Drain the engine oil and refill with fresh 10W30 oil. Run the
engine for about five minutes to circulate oil to all the parts.
See the MAINTENANCE section of this manual for details on
changing oil.
3. Remove the battery, recharge it, and adjust the electrolyte
level. Store the battery in a dry, dark place.
