• Lubricate the drum grease points on
the axles with grease nipples at
every brake pad change or every 12
months.
• Change the hydraulic system filter.
Take your lowbed to the service center
for a grease change of the wheel hub
bearing after 300,000 km or 36 months
of use.
8.6. Hydraulic and Pneumatic Hoses
and Connections
• After the first month, check all the
unions.
• Check the unions again after 6
months.
• These operations should be re-
peated every time oil or air leaks
from the unions.

If oil leakage is detected at the
connections, the tank levels
should be checked.
Replace hoses every three
years to ensure maximum
machine safety.
8.7. Tightening Torques for ISO
Standard Bolts
Bolts should be tightened using a torque
wrench set to the appropriate value. The
tightening torque value is used to pre-
vent the bolts from breaking due to ten-
sion. The following tables show the
tightening torque values (M) for various
metric threaded bolt outer diameters.
These are approximate values for new
and lubricated bolts.
The values in the table will be
used unless special require-
ments are shown in the diag-
rams in the “SPARE PARTS”
manual.
8.8. King Pin
King pin is a shaft which connects truck
and trailer together. Your vehicle may be
equipped with 2” or 3.5” diameter pins.
Please check the king pin diameter be-
fore connecting the truck.
If you match the truck and trai-
ler with a different diameter
king pin, injuries may occur.
The flanged king pin is used on the ve-
hicle. That’s why king pin can be re-
placed easily.
