--- H i t e c h --- m o d e l s (pictures B,B.1,D,D.1):Drill
two holes (Æ11 mm) in the lower side plate of
the cab according to the picture B.1.
Fasten the control valve 30 and cylinder 23 to
the holder 14. Adjust the distance between the
nut and the shoulder of the piston rod to 15 mm
(picture B.2)
NB! put tw o washers between the joint piece
and the lever (picture B.2). F it t h e p r e --- a s -
sembled h older.
Take the control pressure from the brake system
(lower brake t ube) with help of a T--- connector
(37,pictureB), placed instead of a straight con-
nector). Take the working pressure from the
parking brake cylinder with help of a T--- con-
nector (50,pictureB).
--- Fit the hoses and the shield tubes (around the
tubes). The hoses can be connected with the
connectors by pushing.
--- Duo--Matic (pictures C, D):
The Duo---Matic trailer air pressure system has
only a tw o---line system. The control valve
(on e ---
line system)
lacks, and the trailer coupling is differ-
ent.
The mounting can be carried out as previously
described according t o the pictures C and D.
NB! If the tractor has rederse drive controls:
move w ith help of the s leeves 84 the plate 35
(fig. C) backwards. Do not fit the connector 2 .

--- Hand brake adjustment is made w ith the aid of
rod 32 (fig. A).
Adjustment: Adjust the rod length so that the
trailer brake coupling (yellow) gives check pres-
sure of 6,2 -- 7,5 bar when the hand brake lever
is in the second notch of the ratchet plate.
--- Check the tightness of the system. The system
must be so tight that t he pressure drop after the
engine stop is max. 0,15 bar during 10 minutes
(2%).
