BELARUS-1021/1021.3
Operating manual
109
Control lifting or turning the unitized machine with the driveshaft connected to avoid
damaging or thrusting of the driveshaft to the tractor elements. Ensure a safe distance between the
driveshaft and the tractor towing coupler TC-1 (cross-beam on the lower rod ends of the hitch
linkage) 70 mm min.
Turn off the PTO:
- after stopping the tractor, only after the unitized machine completes its operating cycle;
- when lifting the machine to the transport position (for semi-mounted and mounted machines);
- when making sharp turns (for semi-mounted, semi-trailed and trailed machines).
Do not turn on the PTO:
- when the engine tractor is off;
- when the machine is lowered to the ground;
- when the working tools are buried in the ground;
- if the working tool of the machine are carrying process material or are clogged or
jammed;
- if there is an angle of tilt (refraction) of the machine driveshaft in any plane.
Attention!
The manufacturer of the tractor is not responsible and disclaims any warranty for the
tractor PTO and the elements of its drive in the following cases:
-driveshaft from the machine package is damaged.
-type of the said driveshaft does not meet the conditions of unitizing.
- the driveshaft coupling is missing (or damaged, or maladjusted).
-the clutch actuation torque exceeds the permissible torque of the PTO shaft end.
-the PTO shaft end type chosen for the machine drive does not meet the conditions of
unitizing (for each PTO shaft end the maximum allowable power is specified) of the tractor.
No later than every 10 hours inspect the driveshaft state: reliability of fastening of the end
yokes and of the protective enclosure.
Periodically lubricate bearings, telescopic parts of the drive shaft during operation.
Lubrication intervals must be as follows:
- bearings with periodic lubricated of protective enclosure — each shift;
- bearings with periodic lubrication of joints and telescopic parts of the driveshaft in a
temperate climate — each 70 service hours, in a tropical climate — each 16 service hours.
On machines running PTO tractor PTO shaft safety guard must be secured from rotation by
a chain! from rotation, the guards (enclosures) of the driveshaft with protective devices from the
tractor side and the machine side must ensure overlapping by 50 mm min.
Turn on the shaft with a driveshaft connected to it smoothly, gradually increasing its speed
up to the rated. Up to the start of working process, ensure the rated speed of working tools.
Warnings:
-when working with the PTO, make sure no person is in the area of PTO and driveshaft
rotation!
-always turn the PTO when driving up a steep slope and in cases where its operation is not
necessary!
-after turning off the PTO, a danger remains for some time because of the inertial mass of
rotating parts of the machine. During this time do not approach the MTU! Execution of works is
permitted only after a full stop! Make sure to kill the engine and take out the key from the starter and
instrument switch!
-clean, lubricate or adjust a unit driven from the PTO or driveshaft only provided that the
PTO and the engine are off, and the starter and instrument switch key is removed!
- secure disconnected driveshaft on an appropriate bracket! After removing the driveshaft, install
a safety guard on the PTO shaft end.
