Battery Charging
The SA-250 is equipped with a wet charged battery.
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. The system is NEGATIVE GROUND.
PRE-OPERATION SERVICE
READ the engine operating and maintenance instruc-
tions supplied with this machine.
------------------------------------------------------------
Oil
This unit is supplied from the factory with the engine
crankcase filled with a high quality 10W30 oil. This oil
should be acceptable for most typical ambient temper-
atures. Consult the engine operation manual for spe-
cific engine manufacturer’s 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 Operator’s Manual. Make sure the fuel
valve on the sediment bowl is in the open position.
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
container from alternate antifreeze recommendation.)
Fuel can cause fire or explosion.
-
• Stop engine while fueling.

To prevent EXPLOSION when:
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.
To prevent ELECTRICAL DAMAGE when:
a) Installing a new battery.
b) Using a booster.

To prevent BATTERY DISCHARGE, if you have an
ignition switch, turn it off when engine is not
running.
