General
A fully-enclosed operators cab is positioned on four
large rubber anti-vibration mounts to isolate operator
from shock, noise, and vibration. See Figure 1. Op-
erator’s compartment includes electronic controls for
hydraulic systems, steering wheel, instrument panel,
transmission, brake system controls, and operators
seat. An overhead guard forms an integral part of the
operators cab. The cab is installed on a platform above
main frame members. Step plates on both sides of
lift truck give access to cab. The operators cab can
be tilted, providing access to major components. For
major repairs to cab, cab can be completely removed
from frame of lift truck.

INSPECT
WARNING
Do not use tools that can make sparks, heat, or
static electricity. The vapors in the tank can cause
an explosion.
Make a visual inspection of all sides of the tank. Inspect
the welds for cracks and leakage. Check for wet areas,
accumulation of dirt, and loose or missing paint caused
by leakage. Areas of the tank that are not easily seen
can be checked with an inspection mirror and a light that
is approved for locations with flammable vapors.
CLEAN
Tank can be cleaned with or without steam. If steam is
available use a hose with a minimum diameter of 19 mm
(0.75 in.). Control the pressure of the steam by a valve
installed at the nozzle of the hose. If a metal nozzle
is used, it must be made of a material that does not
make sparks. Make an electrical connection between
the nozzle and the tank. Connect a ground wire to the
tank to prevent static electricity.
1. Remove all the parts from the tank. Install the drain
plug.
WARNING
When cleaning the tank, do not use solutions that
make dangerous gases at normal temperatures or
when heated. Wear eye and face protection. Protect
the body from burns. If the tank is cleaned inside a
building, make sure there is enough ventilation.
CAUTION
Disposal of lubricants, fluids, and chemicals must
meet local environmental regulations.
2. Fill the tank with a cleaning solution. Proceed as
follows:
• If steam is available, fill the tank 1/4 full with a so-
lution of water and sodium bicarbonate or sodium
carbonate. Mix 0.5 kg (1 lb) per 4 liter (1 gal).
• If the tank cannot be cleaned with steam, mix
a solution of water and trisodium phosphate or
cleaning compound with an alkaline base. Follow
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.
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.
4. Drain the tank.
5. If steam is available, put steam into the tank until
the tank does not have odors and the metal is hot.
Steam vapors must come from all the openings.
7

Hydraulic Tank 100 YRM 1349
6. Flush the inside of the tank with boiling water. Make
sure all the loose material and cleaning compound
is removed from the inside of the tank.
7. Make an inspection of the inside of the tank. If it
is not clean, repeat Step 5 and Step 6 and make
another inspection. When making inspections, use
a light that is approved for locations with flammable
vapors.
8. Check the tank for flammable vapors. 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 indicator for gas vapors. If
the amount of flammable vapors is above the lower
flammable limit, repeat the cleaning procedures.
ADDITIONAL PREPARATIONS FOR
REPAIR
If nitrogen gas or carbon dioxide gas is available, pre-
pare the cleaned tank for welding using these gases.
See the manual Safe Practices for Welding and Cutting
Containers That Have Held Combustibles by the Amer-
ican Welding Society, F4.1-1999.
If these gases are not available, 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.
REPAIR
Small Leaks
Use the following procedure to repair small leaks:
1. Use steam to clean the area around the leak. Re-
move all paint and dirt around the leak.
2. Apply Loctite® 290 to the leak. Follow the instruc-
tions of the manufacturer.
Large Leaks
WARNING
Special procedures must be followed when large
leaks or other repairs need welding or cutting. All
work must be done by authorized personnel.
CAUTION
Welding on the truck may cause damage to the en-
gine, transmission, and/or hydraulic electronic con-
trol units if proper precautions are not taken. Dis-
connect the negative battery terminal from the bat-
tery. Disconnect all ECM’s. If welding must be done
in a close proximity of an ECM, that ECM must be
removed. When welding to the chassis, attach the
ground cable as close the weld as possible.
1. Use the procedure described under Clean to pre-
pare the tank for repairs.
2. Contact your dealer for Yale lift trucks for welding
instructions.
