the hose. If a metal nozzle is used, it must be made of
a material that does not make sparks. Make an elec-
trical connection between the nozzle and the tank.
Connect a ground wire to the tank to prevent static
electricity.
Steam Method
Use the following procedure to clean the tank with
steam:
1. Remove all the parts from the tank. Install the
drain plug.
2. Fill the tank 1/4 full with a solution of water and
sodium bicarbonate or sodium carbonate. Mix
0.5 kg (1 lb) per 4 liter (1 gal) of water.
3. Mix the solution in the tank using air pressure.
Make sure all the surfaces on the inside of the
tank are flushed with the solution. Drain the
tank.
4. Put steam into the tank until the tank does not
have odors and the metal is hot. Steam vapors
must come out of all openings.
5. Flush the inside of the tank with boiling water.
Make sure all loose material is removed from the
inside of the tank.
6. Make an inspection of the inside of the tank. If it
is not clean, repeat Step 4 and Step 5 and make
another inspection. When making inspections,
use a light that is approved for locations with
flammable vapors.
7. Put plugs in all the openings in the tank. Wait 15
minutes, then remove the inlet and outlet plugs.
Test a sample of the vapor with a special indi-
cator for gas vapors. If the amount of flammable
vapors is above the lower flammable limit, repeat
the cleaning procedures.
Chemical Solution Method
If the tank cannot be cleaned with steam, use the
following procedure:
1. Mix a solution of water and trisodium phosphate
or a cleaning compound with an alkali base. Fol-
low the instructions given by the manufacturer.
WARNING
Compressed air can move particles so that they
cause injury to the user or to other personnel.
Make sure that the path of the compressed air
is away from all personnel.
Wear protective
goggles or a face shield to prevent injury to the
eyes.
2. Fill the tank with the cleaning solution. Use com-
pressed air to mix the solution in the tank.
3. Drain the tank. Flush the inside of the tank with
boiling water. Make sure all the cleaning com-
pound is removed.
4. Make an inspection of the inside of the tank. If
the tank is not clean, repeat Step 1 to Step 3.
Make another inspection of the tank. When mak-
ing inspections, use a light that is approved for
locations with flammable vapors.
5. Check the tank for flammable vapors using a
special indicator for gas vapors. If the amount
of flammable vapors is not below the lower
flammable limit, repeat the cleaning procedures.
OTHER METHODS OF PREPARATION FOR
REPAIR
If nitrogen gas or carbon dioxide gas is available, pre-
pare the tank for welding using these gases. See the
manual Safe Practices For Welding and Cutting Con-
tainers That Have Held Combustibles by the Ameri-
can Welding Society, F4.1 - 1999. If these gases are
not available, another method using water can be
used as follows:
1. Fill the tank with water to just below the point
where the work will be done.
Make sure the
space above the level of the water has a vent.
2. Use acceptable welding practices to repair the
tank.
See the American National Standard
"Safety In Welding And Cutting" AWS Z 49.1 -
1999.
INSTALL
1. Put the tank in position in the frame and install
the hooks.
2. Connect the hydraulic lines to the fittings on the
tank.
3. Install the engine and transmission. Fill the
tank with the correct hydraulic oil. Operate the
system and check for leaks and correct operation.
