presszzre gauge with fifirng A 191835 mounted in place of
the safety vaive.
2) Iristeli the iever A 197816 in the mounting hoies (Fig. 188) and by pressing downwards take up
compieteiy the ciearance existing between cover and support at the lower siop shown with an arrow
(2, Fig. 191) a). In these conditions, the disiance I shouici measure 22,5305 mm ((18865 0.02");
a greater distance means that the surfaces of the iower stop are worn and need added material.
The distance I in cases 1) and 2) of Fig. 190a can be checked using the two ends of the << C30 -
No ~ Go » gauge C 197i3€5.
Adjusting the pfay befween rofler and sector (F;7g. 190 b). — Move the iift controi fever to the highest
position in the sector slot to get fuii raising oi the arms, and place the seiector lever in draft control
(upwards); appiy the iever A 197016 tofhe mounting hoies of the struf to ifs support so as to compieteiy
take up the piay existing between cover and support at the lower stop: in these conditions the distance
between cam and foiiower shouid measure L5 to 2 mm (1/16 to 5/64"). if necessary, the distance can
be corrected by rotating the eccentric on which the foiiower is mounted.
got Note. - Should the working pressure of the lift hydrauiic system need checking, piace e pressure gauge
with fitting A 1933135 in piece of the safety vaive as shown in Fig. 189.
