Lubrication
Lubrication is one of the most important factors determining the durability of separate assemblies and
mechanisms. Timely lubrication and application of appropriate lubricants considerably decreases the early
wear and possibility of the occurrence of failures. Lubricate the semi-trailer in compliance with the following
principles:
before applying lubricant to a lubrication point, clean it;
squeeze lubricant into the lubrication point until used old lubricant appears;
after lubrication, leave a small amount of lubricant on the head of the lubrication point.
Apply lubricant in accordance with the presented diagram (Picture 24 and Table 44).
