PRE-OPERATION SERVICE
READ the engine operating and maintenance
instructions supplied with this machine.
Oil
This unit is supplied from the factory with the engine
crankcase filled with a high quality SAE 10W/30 oil.
This oil should be acceptable for most typical ambient
temperatures. Consult the engine operation manual
for specific engine manufacturerʼs recommendations.
Upon receipt of the welder, check the engine dipstick
to be sure the oil is at the “full” mark. DO NOT overfill.
Fuel
Fill the fuel tank with the grade of fuel recommended
in the Engine Operatorʼs manual. Make sure the fuel
valve on the sediment bowl is in the open position, for
Codes 10950 and below.
Cooling System
The radiator 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 solution as
needed (see engine manual or antifreeze container for
alternate antifreeze recommendations).
BATTERY CHARGING
The D300K 3+3 is equipped with a wet charged bat-
tery. The charging current is automatically regulated
when the battery is low (after starting the engine) to a
trickle current when the battery is fully charged.
When replacing, jumping or otherwise connecting the
battery to the battery cables, the proper polarity must
be observed. This system is NEGATIVE GROUND.

a) Installing a new battery - disconnect the negative
cable from the old battery first and connect the
negative cable to the new battery last.
b) Connecting a battery charger - remove the battery
from the welder by disconnecting the negative
cable first, then the positive cable and battery
clamp. When reinstalling, connect the negative
cable last.
c) Using a booster - connect the positive lead to the
battery first, then connect the negative lead to the
ground lead on the base.
