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.

WARNING

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.

CAUTION

An incorrect arrester may lead to damage to the engine or adversely affect performance. Contact the engine manufacturer for specific recommendations.
