If the mast cannot be lowered, use chains on the
mast weldments and carriage so that they can not
move. Make sure the moving parts are attached to a
part that does not move. See the PERIODIC MAINTE-
NANCE section that was included with your lift truck
for additional information.
Do not try to find hydraulic leaks by putting hands on
pressurized hydraulic components. Hydraulic oil can
be injected into the body by the pressure.
Do the following checks and inspections:
1. Check for leaks in the hydraulic system. Check the
condition of the hydraulic hoses and tubes.
NOTE:
Some parts of the mast move at different speeds
during raising and lowering.
2. Slowly raise and lower the mast several times with-
out a load. Raise the mast to its full height at least
once. The mast components must raise and lower
smoothly in the correct sequence.
3. The inner weldments and the carriage must lower
completely.
4. Raise the mast one meter (three feet) with a capac-
ity load. The inner weldments and the carriage
must raise smoothly. Lower the mast. All moving
components must lower smoothly.
5. Lower the load to approximately 0.3 meter (one
foot). Tilt the mast forward and backward. The
mast must tilt smoothly and both tilt cylinders must
stop evenly.
6. Check that the controls for the attachment operate
the functions of the attachment. See the symbols
by each of the controls. Make sure all of the hy-
draulic lines are connected correctly and do not
leak.
Cooling System (See FIGURE 26.)
WARNING
DO NOT remove the radiator cap from the radiator
when the engine is hot. When the radiator cap is re-
moved, the pressure is released from the system. If
the system is hot, the steam and boiling coolant can
cause burns.
Make sure the coolant level is between the “FULL” and
the “ADD” mark on the auxiliary coolant reservoir. The
coolant will expand as it is heated and the level in the
auxiliary coolant reservoir will increase. If coolant is add-
ed, use the correct mixture of water and ethylene glycol
