5. Slide the quick change ring up over the element
and rotate counter clockwise until an audible click
or pop is heard. If you do not hear the click you
have not rotated the ring far enough and the ele-
ment is not in the locked position. Another indica-
tion that the ring is in the locked position is that one
set (it doesn’t matter which one) of arrows located
on the outside of the ring should be located directly
under the air vent valve.
6. Open the fuel shutoff valve (lever in line with the
hose).
7. Open the air vent valve on the front of the filter
header until fuel emerges free of air bubbles and
then close the air vent valve.
Note: Consult your engine operation manual for
information on air bleeding the entire fuel system.
SECONDARY FUEL FILTER
The Secondary Fuel Filter is a spin on cartridge type
mount directly to the engine. Consult your engine
operation manual for complete information on service
intervals and element changing procedures.
COOLING SYSTEM
The cooling system of the Deutz engine needs to be
checked and cleaned periodically. Consult the engine
owners manual for the proper frequency and proce-
dure.
COOLING BLOWER BELT
The following procedure should be followed to replace
the cooling blower belt:
1. Allow the machine to cool.
2. Unfasten and slide the battery holder out from the
welder.
3. Disconnect the negative battery cable.
4. Remove engine case side.
5. Loosen air cleaner hose clamp and detach hose.
6. Remove screws securing the engine end panel with
air box and air cleaner attached to the base and
roof. Pull this assembly away from roof and base.
This will provide access for removing the belt from
the blower pulley in step 8.
7. Loosen the alternator mounting bolts and rotate the
alternator towards the engine.
8. Remove the old cooling blower belt and install a
new one.
9. Adjust the cold belt tension to 63-73 lbs. midway
between any two pulleys.
10. Reinstall the air cleaner hose, engine case side
and end panel. Reattach the negative battery
cable. Slide in and refasten the battery holder.
11. Check the cooling blower belt tension after 100
hours of operation. (Follow steps 1,2,3,4,,9 & 10)
BATTERY HANDLING
GASES FROM BATTERY can explode.
• Keep sparks, flame and cigarettes away
from battery.
To prevent EXPLOSION when:
• INSTALLING A NEW BATTERY - discon-
nect negative cable from old battery first
and connect to new battery last.
• CONNECTING A BATTERY CHARGER -
Remove battery from welder by discon-
necting negative cable first, then posi-
tive cable and battery clamp. When rein-
stalling, connect negative cable last.
Keep well ventilated.
• USING A BOOSTER - connect positive
lead to battery first then connect nega-
tive lead to 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.

PREVENTING ELECTRICAL DAMAGE
1. When replacing, jumping, or otherwise connecting
the battery to the battery cables, the proper polarity
must be observed. Failure to observe the proper
polarity could result in damage to the charging cir-
cuit. The positive (+) battery cable has a red termi-
nal cover.
2. If the battery requires charging from an external
charger, disconnect the negative battery cable first
and then the positive battery cable before attaching
the charger leads. Failure to do so can result in
damage to the internal charger components. When
reconnecting the cables, connect the positive cable
first and the negative cable last.
PREVENTING BATTERY DISCHARGE
Turn off the RUN/STOP to stop when engine is not running.
