After purchasing the tractor BELARUS -80.1/82.1/820, the dealer (customer) has to
install a muffler on the tractor, and depending on the type of work to be performed, set the
crossbar and rear ends of lower links to the working position. For tractors with a canopy
frame, install the canopy according to section 3.19.5 "Mounting of canopy on the base (on
the basis of universal cabin)" or section 3.19.7 "Mounting of canopy on the base (on the
basis of a small cabin)."

- wash the tractor, remove grease (if there is any on the tractor);
- inspect the tractor carefully, check it for completeness and availability of instruction
manuals;
- remove accumulator batteries, set them into working condition and mount back;
- check outer threaded joints for tightness and tighten more, if necessary;
- check oil level in the engine oil crankcase, in the transmission, in FDA body, in-
termediate support of FDA cardan shaft, bodies of FDA wheel gear groups (on tractors
with FDA 72-2300020-А-04 or 72-2300020-А in upper and lower bevel gear pairs of FDA
wheel gear groups), combined oil tank of HLL and HSC, hydraulic booster body (on trac-
tors equipped with HPS instead of HSC), air cleaner sump and, if necessary top up ac-

for bolts of rear wheel terminal hubs shall make from 300 to 400 Nꞏm, the tightening torque
for bolts of rear wheel bevel hubs shall make from 360 to 450 Nꞏm), tightness of the nuts
