Engine Oil; Coolant; Fuel - Kubota J106-STD Operator's Manual

A The duration of dry charged efficiency, will decrease in
proportion to the period of time elapsed after shipment
and during storage. To obtain the longest service life
of the battery, it is necessary for the battery to be
charged for a sufficient period of time. Continue to
charge until all cells are gassing freely, and the
voltage and specific gravity reading in all cells remain
constant for 3 or more successive readings taken at
30 minute intervals.
A When the battery has been charged fully, the specific
gravity of electrolyte should be 1.270 to 1.290 (at 20 C
=68 F).
BEngine Oil
The generator has been shipped without engine oil.
Fill with oil to the correct level before attempting to
start the engine.
1. Place the machine on a level surface.
2. Remove the oil cap.
3. Add engine oil of grade CD or higher, up to the upper
mark on the oil level gauge.
A See "ENGINE OIL" in "PERIODIC SERVICE" section
for engine oil capacity and checking engine oil level.
BCoolant
To avoid personal injury:
A Place the machine on a level surface.
A DO NOT remove the radiator cap
while coolant is hot. When cool,
rotate the radiator cap slowly to the
first stop to allow excess pressure to
escape. Then
completely.
1. Remove the radiator cap and fill with specified coolant
until the coolant level is just below the port.
2. Fill with coolant to the "FULL" mark on the reserve
tank.
3. Securely tighten radiator cap and reserve tank cap.
A See "RADIATOR" in "PERIODIC SERVICE" section
for changing coolant.

PRE-OPERATION CHECK
BFuel
To avoid personal injury:
A DO NOT refuel when engine is
running or hot.
A Always shut off the engine before
refueling.
A DO NOT overfill fuel system. If any
fuel overflows, wipe it up completely
before starting operation.
A When refueling, keep all flames,
sparks and cigarettes away from
generator.
1. Always fill the fuel through the fuel tank strainer.
2. Make sure that dirt or water does not enter the fuel
tank.
3. Fill with Diesel fuel No.2-D (ASTMD975).
4. Below 0 C (32 F) a mix of No.1-D and No.2-D is
acceptable.
5. Fuel level is read by fuel gauge.
A If the fuel tank should empty completely causing the
engine to stop, then the fuel system requires air
bleeding after filling the tank and before restarting the
engine.
(See "Air Bleeding the Fuel System" in "PERIODIC
SERVICE" section.)
