3. MAINTENANCE
WolfPac 3100/WolfPac 3100R/WolfPac 3100D
Check the full speed, Honda and Kubota 3,400 +/- 100
and adjust full speed stop screw as required.
Notice the idle and full speed RPM setting should not
be modified or eccentric system may be damaged. See
Eccentric for proper operating speed.
3.12 GAS AIR-COOLING SYSTEM
The machine should be cleaned at scheduled
maintenance. This should include cleaning the air inlet
screens and the engine cooling fins. Wash machine with
warm soapy water, rinse off mud and dirt with water,
and use pressurized air (30-psi max.) to blow dirt and
debris from engine.
3.13 CHECKING COOLANT LEVEL/
ADDING COOLANT
The Kubota diesel engine is equipped with a radiator
and reserve tank. Check coolant level daily. Level
should be between the full and low marks on the
reserve tank. When coolant level drops due to
evaporation, add water only up to the full level.
3.14 CHANGING COOLANT/
CHECKING RADIATOR HOSES & CLAMPS
To drain coolant, always open both drain cocks and
simultaneously open the radiator cap as well. Remove
overflow pipe to drain reserve tank. The radiator
capacity is approximately .82 gallons (3.1 liters). Use
clean, fresh water and 50% anti-freeze to fill radiator.
Check radiator hoses and clamps every 200 hours for
leaks or cracks. Replace every 2 years or earlier if
hoses are swollen or cracked.
ENGINE IS EQUIPPED WITH HIGH
TEMPERATURE SHUT DOWN. ROLLER WILL
SHUT DOWN IF RADIATOR TEMPERATURE
EXCEEDS 226° F (108° C)
TO AVOID PERSONAL INJURY:
 DO NOT STOP ENGINE SUDDENLY,
STOP IT AFTER ABOUT 5 MINUTES OF
UNLOADED IDLING.
 WORK ONLY AFTER LETTING THE
ENGINE AND RADIATOR COOL OFF
COMPLETELY (MORE THAN 30
MINUTES AFTER IT HAS BEEN
STOPPED).
 DO NOT REMOVE THE RADIATOR CAP
WHILE COOLANT IS HOT. WHEN
COOL TO THE TOUCH, ROTATE CAP
TO THE FIRST STOP TO ALLOW
EXCESS PRESSURE TO ESCAPE. THEN
REMOVE CAP COMPLETELY.
 IF OVERHEATING SHOULD OCCUR,
STEAM MAY GUSH OUT FROM THE
RADIATOR OR RESERVE TANK; SEVER
BURNS COULD RESULT.
 WHEN USING ANTI-FREEZE, PUT ON
SOME PROTECTION SUCH AS RUBBER
GLOVES.
 IF YOU SHOULD DRINK ANTI-FREEZE,
THROW UP AT ONCE AND TAKE
MEDICAL ATTENTION.
 WHEN ANTI-FREEZE COMES IN
CONTACT WITHTHE SKIN OR
CLOTHING, WASH IT OFF
IMMEDIATELY.
 DO NOT MIX DIFFERENT TYPES OF
ANTI-FREEZE.
