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
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
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 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 battery
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 the negative battery
cable terminal.
NOTE: This machine is furnished with a wet charged
battery; if unused for several months, the battery may
require a booster charge. Be sure to use the correct
polarity when charging the battery.
EXHAUST DEFLECTOR
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 avail-
able for your RANGER 300. See the Accessories sec-
tion of this manual for more information.
An incorrect spark arrester may lead to damage to the
engine or reduce performance.
