2.2. General design
Rotary snow blower Tornado generally consists of linkage, working assembly and hydraulically
adjustable blowing tube.
Drive is transmitted from tractor's PTO shaft by telescopic articulated shaft (6) onto gearbox (4).
The gearbox powers blower's rotor (11) and milling screw (10) through intermediate telescopic
articulated shaft (7) and chain gear (5).
Tornado blowers can have optionally mounted tube extension (9). Blowing tube along with its
extension has been designed so as to enable quick mounting and dismounting of these parts.
Therefore, if there is need for quick dismounting of the tube for repair, transport or performing extension
(distraction), it is enough to unlock and take out mounting pins located at the tube (extension) base,
and then separate the tube and the extension. In order to re-mount blowing tube, perform the above in
reverse order.

perfect technical condition. If it is otherwise, then repair or replace worn out (missing) parts with new
ones and tighten loosen bolts in accordance with Tab. 5.
Next, on each blower's start, examine oil level in main drive gear and if need be refill and lubricate
the machine (information on oil are provided in section 5.3).
Upon lifting the blower up, adjust position (height) of sliding skids (Fig. 12). Unlock and take pin
(1) out, set skid (2) in desired position and then lock with pin (1) again. If the blower is ready for
operation set it desired position and start clearing snow.

4.6. Operation
NOTE:
Snow clearing rate should always be adjusted depending on current road
conditions. When clearing snow, do not drive faster than 5 km/h.
NOTE:
DO NOT operate the blower, if any unauthorized personnel, animals and
buildings are within snow blowing range.
Prior to lowering and starting the machine, which is mounted on the tractor, make sure whether
there are no unauthorized personnel (children in particular) or animals within the operating reach. The
blower's operator is obliged to provide good visibility of the machine and operating range. When
operating with the blower it is forbidden to take any place other than the operator's seat in the vehicle's
cabin or to leave the cabin during operation.
Rotary snow blower Tornado has been designed to be operated at the front with possibility of
mounting it on a rear linkage. However, front PTO drives might not transmit such high torque as rear
ones. This is why with snow's large weight, which is to be put aside or cleared, the blower needs to be
aggregated with tractor on rear-3point linkage with recommended PTO shaft's rate of
540 rpm. Owing to this, the blower operates more smoothly and does not load the tractor as when
mounted on the front 3-point linkage. As it is recommended by the manufacturer, if snow cover height
is more than 50 cm, then operating rate should be reduced or the blower should be mounted on
tractor's rear 3-point linkage. Figure below provides blower's all possible working positions.

4.7. Dismounting blower from the tractor
Once operation is over, clean the machine and if need be put it aside in a rest place previously
setting sliding skids so that the blower upon its lowering onto the ground rests stable on a cleaning
blade and skids. In order to dismount the machine and tractor perform the described steps in reverse
order as in case of mounting (4.1. Mounting blower to tractor), while hang the telescopic articulated
drive shaft on a corresponding holder, which can be found on the catch.
