the key 2 by 180° and pushing the button 3. To lock the left door from outside it is necessary to
turn the key by 180° in an opposite direction.
To adjust the door positioning relative to the door aperture the following shall be done:
- loosen bolts 1 (figure 3.23.5) fastening hinges 2 to the cab frame supports, find an
effective position of the door (a positive minimum allowance between the door contour and
the door aperture contour should be 2 mm), tighten the bolts.
- adjust position of the catch 4 (figure 3.23.4), having loosened bolts 3 (figure 3.23.3),
moving the catch in a vertical plane achieve optimal up/down position relative to the lock. Ad-

the lock (there should be no gaps between door weather strip and the door aperture).
