I t is strictly forbidden to use the rear
hinging when the trailer gear is in -
stalled on the tractor!
The trailers shall be used at the speeds
defined by the road conditions. It is al-
lowed to operate the trailers 2ПТС-4-
887А with the body capacity of 20 and
45 m
3
at the speeds of up to 15 km/h,
since their stability is lower. Avoid sharp
turns of these trailers and broadcaster
1РМГ-4 to prevent damage of fenders of
their rear wheel.
The trailer eye (2ПТС-4-785А, etc) shall
be fixed against slipping to avoid its
jamming.
During the operation, the fork ТСУ-1Ж
shall be fastened to the cross-bar of
the hitch with two pins. It is forbidden
to use the fork fixed with one pin.
Prior to operation, make sure that the
pins and the pivot bolt of the hitch fork
are reliably splinted. All the trailer signal-
ling units (stop and turn indicator lights,
number plate lighting) are to be con-
nected via the plug socket mounted on
the tractor.
Trailer brakes with pneumatic or hydrau-
lic actuator are controlled through the
tractor pneumatic system.
Using the optional equipment of the
tractor
As optional equipment, a rear driving pul-
ley, side PTO, additional weights for
loading the front axle, speed reducer, au-
tomatic hitching CA-1, spacer plate for
installing the twinned rear wheels and
other equipment can be mounted on the
tractor.
A rear pulley is installed on the rear
PTO reducing gear cover and driven
by the PTO slotted shank. To prevent
the PTO shank deformation, ensure
obligatorily the installation of the hous-
ing onto four studs with centring the
flange in the PTO cover. Use the PTO
control lever for engaging and disen-
gaging the pulley.
The side PTO is installed instead of left
cover of the gearbox with leading the con-
trols into the cab. It may be used for addi -
tional drive of mechanisms and operating
elements of the machines of front and
side hooking.
The additional weights with the total
weight of 220 or 510 kg are mounted on-
to a special holder, which is fastened to
the front beam of the tractor.
To provide the possibility of using the
tractor with the machines requiring lower
speeds, a speed reducer is installed.
The speed reducer additionally decreas-
es tractor speeds at I and II gears during
forward and reverse motion (the speed
reducer is optional).
To install a speed reducer on the trac-
tor, follow the recommendations stated in
the “Technical Description and Operation
Manual for the Speed Reducer” enclosed
to each speed reducer shipped against
the customer’s order.
IMPORTANT! Having installed a
speed reducer on the tractor, fill in
power transmission with oil to the
check plug level and add more 10 li-
tres.
