4) Checking the vertical play of the coupling pin:
Check that the vertical play of the coupling pin (14) is no more than 4 mm. The
play "S" is to be measured by pushing the tip of the pin upwards when the
operating handle (22A-22B) is down (see figure on page 19/32).
In case the play exceeds the limit replace the lift lever (15) (see chapter 5.3
REPLACEMENT OF THE LIFT LEVER SPRINGS, page 23/32);
5)
Checking for play in the operating handle:
Check that the free movement of the operating handle (22A-22B) is less
than 10° (degrees) as shown in the figure. In case the limit is exceeded
replace the operating handle (22A-22B) and the lift lever (15) (see
chapter 5.3 REPLACEMENT OF THE LIFT LEVER SPRINGS, page 23/32);
6)
Checking the torque of the screws and bolts:
Check that the torque of the screws (21) is M = 50 Nm and that the torque
of the fixing bolts (24) is as given in point 1 in chapter 2 INSTALLATION on
page 10/32;
7)
Lubrication:
Grease the mechanism unit (20a) through the grease nipple (29) on the right
side of the mechanism box (see the figure on page 17/32).
Always grease the mechanism with the coupling pin (14) raised (see point 1 in
chapter 3.1. COUPLING UP on page 12/32). Do not over grease.
