TABLE 5.1 REQUIREMENTS REGARDING THE JACK
LIFTING CAPACITY 2 000 kg
HEIGHT OF COMPACTED JACK 280 mm
Replacement of bearings, lubrication as well as works connected with braking system and
carriageable axes must be performed my qualified technicians.
Checking bearing slackness and technical condition of bearings of carriageable axle
must be done after first month of operation and then every 6 months of further
performance.
5.2 MAIN BRAKE ADJUSTMENT
Brakes need to be adjusted if:
•
in consequence of abrasive wear of brake lining, the excessive slackness occurs
between lining and brake drum. In such case braking efficiency is reduced,
•
brakes of both wheels operate unequally and unevenly.
When having properly adjusted brakes, braking of both wheels must happen at the same
time. Adjusting brakes consists in changing position of expander’s arm (1) with relation to
expander’s roll (2). In order to do so, one ought to take off the snap ring and washer (3),
dismantle expander’s lever and position it in the right direction, i.e.:
•
backward – if brake is retarded (A)
•
forward – if braking happens to early (B)
