ENGINE COOLING SYSTEM
The cooling system has been filled at the factory with
a 50-50 mixture of ethylene glycol antifreeze and
water. Check the radiator level and add a 50-50 solu-
tion as needed. (See Engine Manual or antifreeze con-
tainer for alternate antifreeze recommendation.)
BATTERY CONNECTION
WARNING: Use caution as the electrolyte is a strong
acid that can burn skin and damage eyes.
Remove and discard the insulating caps from the neg-
ative battery terminals. Attach and tighten negative
battery cable terminals.
NOTE: This machine is furnished with wet charged
batteries; if unused for several months, the batteries
may require a booster charge. Be careful to charge the
batteries with the correct polarity. Make sure that the
batteries are level while charging.
GASES FROM BATTERY can explode.
● Keep sparks, flame and cigarettes
away from battery.
To prevent EXPLOSION when:
● INSTALLING A NEW BATTERY — disconnect
negative cable from old battery first and
connect to new battery last.
● CONNECTING A BATTERY CHARGER —
remove battery from welder by disconnecting
negative cable first, then positive cable and
battery clamp. When reinstalling, connect
negative cable last. Keep well ventilated.
● USING A BOOSTER — connect positive lead to
battery first then connect negative lead to neg-
ative battery lead at the lower control panel
support.
BATTERY ACID can burn eyes and
skin.
● Wear gloves and eye protection
and be careful when working near
battery.
● Follow instructions printed on battery.
IMPORTANT: To prevent ELECTRICAL DAMAGE
WHEN:
a) Installing new batteries.
b) Using a booster.
Use correct polarity — Negative Ground.
To prevent BATTERY BUCKLING, tighten nuts on bat-
teries only until snug. DO NOT OVERTIGHTEN.
SPARK ARRESTER
Some federal, state or local laws may require that
gasoline or diesel engines be equipped with exhaust
spark arresters when they are operated in certain loca-
tions where unarrested sparks may present a fire haz-
ard. The standard muffler included with this welder
does not qualify as a spark arrester. When required by
local regulations, a suitable spark arrester must be
installed and properly maintained.
An incorrect arrester may lead to damage to the engine
or adversely affect performance. Contact the engine
manufacturer for specific recommendations.
