10-10
OIL LEAK TEST
LIFTING CYLINDERS
1. Set mast in vertical position with the standard load on
forks
2. Lift forks at 3 m and take the measure between the forks
and ground with a meter and leave the key switch ON
3. Make the measurement between forks and ground or
between the datum lines on the inner and outer masts
again after 10 minutes
Limit: A = 100 mm
4. If there are oil leakages on the body of the lifting
cylinders, check if cylinder connections are well tight.
Replace the cylinder if necessary
TILTING CYLINDERS
1. Set mast in vertical position with the standard load on
forks, lift forks at 3 m and leave the key switch ON
2. Secure the lead rope on the front edge of the top of the
mast; measure the distance between the rope and the
mast 1 m lower
3. Perform the same measurement 10 minutes after
(1° = 17.4 mm)
Limit: Maximum forward angle (°) <= 0.5 (°/min)
Time (10 min)
4. If the truck is out of the above limit lower completely the
mast and turn the key switch OFF
5. Invert the tilting hoses with the sideshift hoses (if
present) on the control valve. This operation is
necessary to understand if there is any internal leakage
inside the tilting cylinder or the control valve
6. Turn the key switch ON and repeat the test from point 1
to 3; after that
a) The test result is within the set limits:
replace the control valve
b) The test result is not within the set limits:
replace the tilting cylinders
