Checking and Refueling

To avoid personal injury:
A

Do not smoke while refueling.

Be sure to stop the engine and remove the key
before refueling.

To avoid allergic skin reaction:
A

Wash hands immediately after contact with
diesel fuel.

1. Turn the key switch to "ON", check the amount of fuel

by fuel gauge.

2. Fill fuel tank when fuel gauge shows 1/4 or less fuel in

tank.

3. Use grade No.2-Diesel fuel at temperatures above

-10

Use grade No.1-Diesel fuel at temperatures below
-10

Do not permit dirt or trash or water to get into the fuel
system.

Be careful not to let the fuel tank become empty,
otherwise air will enter the fuel system, necessitating
bleeding before next engine start.

Be careful not to spill fuel during refueling. If a spill
should occur, wipe it off at once, or it may cause a fire.

To prevent condensation (water accumulation) in the
fuel tank, fill the tank before parking overnight.

Checking Engine Oil Level

To avoid personal injury:
A

Be sure to stop the engine and remove the key
before checking the oil level.

1. Park the machine on a firm, flat and level surface.
2. Check engine oil before starting the engine, or, after 5

minutes or more when the engine has been stopped.

3. To check the oil level, draw out the dipstick, wipe it

clean, replace it, and draw it out again. Check to see
that the oil level lies between the two notches.
If the level is too low, add new oil to the prescribed
level at the oil inlet.
(See "LUBRICANTS" in "MAINTENANCE OF THE
TRACTOR" section.)

(1) Fuel tank cap

Fuel tank capacity

25 L

(1) Oil inlet
(2) Dipstick

(A) Oil level is acceptable within this range.

PERIODIC SERVICE OF THE TRACTOR

When using an oil of different maker or viscosity from
the previous one, remove all of the old oil and oil filter.
Never mix two different types of oil.

If oil level is low, do not run engine.

When using BT602 Backhoe and checking oil level,
locate the tractor/loader/backhoe on a flat and set the
loader/backhoe as illustrated below.

Checking Transmission Fluid Level

1. Park the machine on a firm, flat and level surface,

lower the implement to the ground and stop the
engine.

2. To check the oil level, draw out the dipstick, wipe it

If oil level is low, do not run engine.

Checking Coolant Level

To avoid personal injury:
A

Be sure to stop the engine and remove the key
before checking coolant level.

Do not remove the radiator cap while coolant is
hot. When cool, slowly rotate cap to the first
stop and allow sufficient time for excess
pressure to escape before removing cap
completely.

1. Check to see that the coolant level is between the "H"

and "L" marks of recovery tank.

2. When the coolant level drops due to evaporation, add

soft water only. In case of leakage, add antifreeze and
soft water in the specified mixing ratio up to the "H"
level.
(See "Flushing Cooling System and Changing
Coolant" in "EVERY 2 YEARS" in "PERIODIC
SERVICE OF THE TRACTOR" section.)

If the radiator cap has to be removed, follow the above
"CAUTION" and securely retighten the cap.

Use clean, fresh soft water and anti-freeze to fill the
recovery tank.

If water should leak, consult your local KUBOTA
Dealer.
