water accumulation or sediment. Empty fuel pre-
filter.
ENGINE ADJUSTMENT

BATTERY MAINTENANCE
To access the battery, Disconnect the Negative and
then Positive battery cables. Remove the 4 screws
from the battery door using a screwdriver or a 10mm
socket. Remove the 2 nuts from the battery bracket
using a 11mm wrench or socket. Slide the battery out
and remove from welder.
GASES FROM BATTERY can explode.
G
Keep sparks, flame and cigarettes
away from battery.
To prevent EXPLOSION when:
G
INSTALLING A NEW BATTERY — disconnect
negative cable from old battery first and con-
nect to new battery last.
G
CONNECTING A BATTERY CHARGER —
remove battery from welder by disconnecting
negative cable first, then positive cable and bat-
tery clamp. When reinstalling, connect
negative cable last. Keep well ventilated.
G
USING A BOOSTER — connect positive lead to
battery first then connect negative lead to nega-
tive battery lead at engine foot.
BATTERY ACID can burn eyes and
skin.
G
Wear gloves and eye protection and
be careful when working near bat-
tery.
G
Follow instructions printed on battery. RANGER® 305D (CE)

OVERSPEED IS HAZARDOUS

The maximum allowable high idle speed for this
machine is 3150 RPM, no load. Do NOT tamper
with governor components or setting or make any
other adjustments to increase the maximum
speed. Severe personal injury and damage to the
machine can result if operated at speeds above
maximum.

CLEANING THE BATTERY

Keep the battery clean by wiping it with a damp cloth
when dirty. If the terminals appear corroded, discon-
nect the battery cables and wash the terminals with an
ammonia solution or a solution of 113g (1/4 pound) of
baking soda and 0.9461L (1 quart) of water. Be sure
the battery vent plugs (if equipped) are tight so that
none of the solution enters the cells.
After cleaning, flush the outside of the battery, the bat-
tery compartment, and surrounding areas with clear
water. Coat the battery terminals lightly with petroleum
jelly or a non-conductive grease to retard corrosion.
Keep the battery clean and dry. Moisture accumula-
tion on the battery can lead to more rapid discharge
and early battery failure.

CHECKING THE ELECTROLYTE LEVEL

If battery cells are low, fill them to the neck of the filler
hole with distilled water and recharge. If one cell is
low, check for leaks.

CHARGING THE BATTERY

When you charge, jump, replace, or otherwise con-
nect battery cables to the battery, be sure the polarity
is correct. Improper polarity can damage the charging
circuit. The RANGER® 305D (CE) positive (+) battery
terminal has a red terminal cover.
If you need to charge the battery with an external
charger, disconnect the negative cable first, then the
positive cable before you attach the charger leads.
After the battery is charged, reconnect the positive
battery cable first and the negative cable last. Failure
to do so can result in damage to the internal charger
components.
Follow the instructions of the battery charger manu-
facturer for proper charger settings and charging time.
SERVICING SPARK ARRESTOR
Clean every 100 hours or twice a year, whichever
occurs frist.
1. Stop engine and allow to cool.
2. Loosen clamp and remove spark arrestor from machine.
3. Remove locknut on top of spark arrestor housing and lift
off cap.
4. Separate plates and clean with a wire brush if neces-
sary.
5. Inspect plates and housing for holes or cracks. Replace
if damaged.
6. Reassemble and reinstall on to muffler outlet pipe.
