The VANTAGE
®
520 SD is equipped with a fuel pre-filter / water
separator before the electric lift pump and a fuel filter after the lift
pump and before the injectors. Open the drain on the fuel pre-filter /
water separator and drain out any water daily. Close drain when
diesel fuel starts to come out. If excessive water is in the fuel, the
engine will not start. The procedure for changing the filter is as
follows.
1. Close the fuel shutoff valve.
2. Clean the area around the fuel filter head. Remove the filter.
Clean the gasket surface of the filter head and replace the o-
ring.
3. Fill the clean filter with clean fuel, and lubricate the o-ring seal
with clean lubricating oil.
4. Install the filter as specified by the filter manufacturer.
Over tightening will distort the threads, filter element seal or
filter can.

COOLING SYSTEM
The cooling system of the Deutz engine needs to be checked and
cleaned periodically. (Consult the engine Owners Manual for the
proper procedures and frequency).
Coolant needs to be added at the radiator filler neck after remov-
ing cap when system is cool. Fill to top of filler neck. Engine will
not start if coolant level is too low.
The coolant system is equipped with an internal expansion tank
located inside the top radiator tank. This allows for normal thermal
expansion and contraction of the engine coolant. The system is fit-
ted with a “catch only” reservoir to keep any rejected or excess
coolant from entering the environment. Check periodically and
empty as required. Do not fill with coolant.
BATTERY HANDLING
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 con-
nect 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
engine foot.
BATTERY ACID CAN BURN EYES AND SKIN.
• Wear gloves and eye protection and be careful when work-
ing 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 circuit. The positive (+) battery cable has a red ter-
minal cover.
2. If the battery requires charging from an external charger, dis-
connect 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 the RUN/STOP switch to stop when engine is not running.
PREVENTING BATTERY BUCKLING
Tighten nuts on battery clamp until snug.
