FUEL

Fill the fuel tank with clean No. 2, diesel fuel only. Do not fill to the top of the filler neck to allow room for expansion.

The RANGER 300 has a 10 gallon (38 liter) fuel tank with a top fill and fuel gauge mounted on the control panel. See the OPERATION and MAINTENANCE sections of this manual for more details about fuel.

ENGINE COOLANT

WARNING

HOT COOLANT can burn skin.

• Do not remove cap if radiator is hot.

------------------------------------------------------------------------

The welder is shipped with the engine and radiator filled with a 50% mixture of ethylene glycol and water. The recovery bottle should be partially filled. See the MAINTENANCE section and the engine Operator’s Manual for more information on coolant.

BATTERY CONNECTIONS

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 nega- tive 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 negative battery lead at engine foot.

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.

The RANGER 300 is shipped with the negative bat- tery cable disconnected. Before you operate the machine, make sure the Engine Switch is in the OFF position and attach the disconnected cable securely to the negative (-) battery terminal.

Remove the insulating cap from the negative battery terminal. Replace and tighten negative battery cable terminal. NOTE: This machine is furnished with a wet charged battery; if unused for several months, the bat- tery may require a booster charge. Be sure to use the correct polarity when charging the battery.

EXHAUST DEFLECTOR

CAUTION

Shut off the machine and allow the muffler to cool before touching the muffler.

------------------------------------------------------------------------

The RANGER 300 is shipped with the exhaust deflec- tor detached. Install it on the muffler outlet using the clamp supplied. Rotate the deflector to the desired direction before tightening the clamp.

SPARK ARRESTER

Diesel engine mufflers may emit sparks when the engine is running. Some federal, state, or local laws require spark arresters in locations where unarrested sparks could present a fire hazard.

Standard muffler and deflectors (like the ones includ- ed with the RANGER 300 do not act as spark arresters. When local laws require it, a spark arrester must be installed on the machine and properly main- tained. An optional spark arrester kit (K903-1) is available for your RANGER 300. See the ACCESSORIES section of this manual for more infor- mation.

CAUTION

An incorrect spark arrester may lead to damage to the engine or reduce performance.
