Belarus – 90/92 Operating manual
Self-contained instruments Index of temperature of cooling liquid(1) Index (1) shows temperature of cooling liquid of diesel engine in degrees. Scale has three zones: - working – 80 - 100º С – green colour; - warning – 40 - 80º С – yellow colour; - emergency – 100 - 120º С – red colour;
IMPORTANT! If device shows absence of charge of storage battery, check condition and tension of drive belt of fan. Index of oil pressure in diesel engine (4)
Index of fuel level (3) Index (3) shows quantity of fuel in tank. Do not assume full bleeding of fuel tanks in order to prevent hit of air in fuel system. Device has division: 0 – 0,5 - P
At diesel engine work watch instrument registration. Normal pressure of oil 1...5 kgs/sm2 (green sector of scale). It is possible to increase pressure till kgs/sm2 on cold diesel engine. IMPORTANT! Do not permit diesel engine work with instrument registration in red zones of scale at nominal mode. It is too low or it is absent , stop diesel immediately, find and eliminate malfunction.
Indicator of voltage (2)
It shows voltage of storage battery at idle diesel engine, when key of switch of starter (1) is in a position «I». At diesel engine Тachospidometer (5) operation index of voltage shows voltage in 1. White background — scale of speeds of onboard network of tractor. tractor moves (km/h) for II, III, IV Condition of feed system rangers (5... 16 gears) gear box. Zone on scale, At diesel At idle diesel 2 and 3. Green background — scale of colour engine work engine frequency of rotation of independent 13,2 – 15,2 В Normal mode rear PTO (rev/min); green of charge 4. Black background — scale of high10,0 – 12,0 В Generator Storage speed mode of diesel engine (rev/min); red does not battery is operate discharged 5. Scale of operating time of diesel 12,0 – 13,2 В Charge of Storage engine in motor hours. yellow
