NYLON TUBE REPLACEMENT METHOD
•
In this vehicle, nylon tubes are used for all the air tubes except those
on the charge line and the rear axle, the tubing for the wheel power
signal, a portion of the accessory system tubing, and for the unloader
tubing, and it is also used in joints, depending on the connection con-
ditions of the two types of joints; one-touch joints and caulking joints.
NOTICE
Since the function and quality of nylon tubes and joints are guaran-
teed as tube and joint sets, the use of parts other than Hino Genuine
Parts must be avoided.

2. REMOVAL OF A ONE-TOUCH JOINT
(1) Make sure there is no dirt or grease stuck to the connector end. If the
end is dirty, clean it thoroughly by air blowing or other means.
(2) Using the special tool for removing the nylon tube to push the connec-
tor end, pull off the nylon tube with your hand in one stroke, without
stopping partway, pulling the tube in the connector axial direction.

INSTALLATION OF A ONE-TOUCH JOINT AND CAULK-
ING JOINT
•
Make sure the joint interior is free of dirt grease. If the interior is dirty,
clean it thoroughly by air blowing or other means.
• Cut off the tube end where the tube surface is scarred by the joint
pinch marks, and make sure that the part of the tube inserted into the
joint has no surface damage. If the tube is damaged, cut off the dam-
aged part (provided that the tube length is more than sufficient).
NOTICE
Use the special nylon tube cutter when cutting the nylon tube, and cut
the tube so that the angle of the cut end to the axial center is 85-95
