Danger!

Remember to turn on the wide load lights, warning systems, preferably use low gears and do not exceed the speed limits of the highway code.

Danger!

Do not stand within the range of action of the TF front snow cutter blower and always keep a safety distance.

Danger!

Do not stand within the range of action of the snow jet.

Danger!

Never leave the wheel loader unattended while the milling drums are running.

During the work phase, the operators must stay on the seats in the driver's cab.

The clearance speed must be adapted to specific conditions.

Danger!

The snow jet coming from the high speed channel can be dangerous for people, animals, and objects.

Pay the utmost attention when you rotate the channel and when you work in a team.

Note: When working in the presence of high snow, the curve mobility is affected.

Moreover, keep in mind that the clean area behind the front snow cutter-blower is slippery and that the front axis can be unloaded when the front snow cutter-blower is pressed on the road surface. Snow chains must be applied to the four wheels of the carrier wheel loader, except when removing snow sludge from the roads.

Take the TF front snow cutter-blower to the ground by shifting the lifting lever to neutral.

 Adjust the height of the shoes to allow the blade to stay at least 10 mm from the ground. 

Move the discharge chute to the required direction to unload the snow.

Danger!

Before choosing the discharge direction, make sure that no person or object stands in the vicinity as they can be invested by a snow jet.

Remember that on average the front snow cutter-blower makes a launch of 15m - 30m and that sharp objects can be mixed with snow.

Danger!

Pay attention when you adjust the deflector of the chute as the jet may injure persons or damage objects, therefore, never direct the jet towards persons or objects.

• Deflector door raised: snow is discharged far away from the wheel loader; •

Deflector door lowered: snow is discharged close to the vehicle.

Prevent conditions that may tilt the vehicle. Moreover, avoid working on significant slopes, close to cliffs, ledges or areas subject to landslides, climbing on snow drifts with the motor, or other similar conditions.

The operator, therefore, must know the work area well and the pathway must have been previously marked with stakes and flags(Fig.2-4).

Check in advance the pathway and make sure it is fully marked.

Otherwise, use specific snow sensors and have authorized and qualified personnel on site. .

4.Spreading operation

4.4 Clearing the road This is the easiest condition. The snow depth is lower than the roller diameter. Under these conditions, the wheels are in contact with the ground.

Caution!

Given the danger involved when working with the TF front snow cutter blower, make sure that the truck and sweeper unit work regularly and efficiently before starting the operations.

Make sure that the work area is free from unauthorised people and that no one stands within the range of action of the TF front snow cutter blower (Fig.3-4).

In the event clearing operations must take place in crowded areas, the work area must be marked by personnel on the ground provided with suitable signalling.

Fig. 3-4

Accept signals only by authorised personnel.

Engage low gears.

Engage the all-wheel drive.

Take the TF front snow cutter-blower to the maximum number of revs Set the TF front snow cutter-blower to floating position Engage the most suitable gear according to the type and amount of snow, gradually tackling the snow layer and keeping a constant travelling speed In the event the front snow cutter-blower climbs on the snow instead of grinding it, creating a ramp effect, move backwards with the wheel loader and proceed working on flat ground. In the event this procedure fails to solve the problem, press the blade on the ground using the pistons of the lifting system until you create a horizontal surface. At this point, set the TF front snow cutter-blower to floating mode (Fig.4-4).

CAT194_Rev.00

PAG. 4-9

4.Spreading operation Avoid creating oscillations or steps as much as is possible. In these events, always move backwards and proceed working on flat ground.

Take into consideration the minimum turning radius of the motor before approaching hairpin turns.

In the event the curve cannot be made all at once, move by sections, i.e. move forwards and backwards, advancing little by little (Fig.5-4).

Fig. 5-4

During clearing operations, pay attention to foreign bodies that may be found in the snow and remove them manually.

Caution!

Snowslides coming from rocks or material mixed with snow cannot be cleared directly with the front snow cutter-blower but must be cleared by other means. The presence of stones, large branches, etc. may damage the rollers.  To clear unpaved roads adjust the shoes to allow the blade to stay as high as possible compared to the ground, avoiding touching the stony ground. The layer of snow that remains on the road is compacted by the passage of the front snow cutter-blower, therefore, it can be crossed only by using chains.

CAT194_Rev.00

PAG. 4-10

4.Spreading operation 4.5 Clearing operations under floating conditions This condition occurs when the snow layer considerably exceeds the roller diameter.

In this event, climb on the "floating" snow layer and work by subsequent passages.

You can "float" in the following cases: 1- Clearing the snowpack; 2- Clearing trenches; 3- Clearing across a mountainside.

4.5.1 Clearing a snowpack (Fig.6-4)

Fig. 6-4

It may occur that the road is blocked by a snowpack due to a snowslide or landslide. In these events, take the following measures.  Make sure that the consistency of the snow layer can withstand the weight of the TF front snow cutter-blower. An empiric system for that control consists in covering the pathway by foot, as the specific ground pressure on the front snow cutter-blower is approximately equivalent to that of the person.  Check the longitudinal slope of the snowpack area (max. 30%). If required, move forward directing the chutes to the front in order to make a fill area and stay within the minimum limit compatible with the characteristics of the whell loader. Remember that adherence conditions are always precarious.  Gradually tackle the slope keeping a passing depth equal to 3/4 of the max. diameter of the sweeper rollers.  Continuously adjust the height of the TF front snow cutter-blower to prevent the rollers from creating steps.

Remove the shoes if the problem persists.

A stepped profile requires increased traction force compared to a gradual profile, therefore, slopes are more difficult to tackle.

4.Spreading operation

Fig. 7-4

 Always create a horizontal work ground. In the event the TF front snow cutter-blower inclines on one side, go back and proceed working on a flat ground.  Stop on the top of the snowpack as soon as the front snow cutter-blower is discharged and do not move forward. It is important that the snowpack top is cleared. Do not sweep downhill once you have reached the top of the snowpack. This way, the forward thrust will be added to the weight of the wheel loader and it will be difficult to go back with the reverse gear (Fig.8-4).

Fig. 8-4

 After the first passage and once you have reached the top of the snowpack, go back to the starting point and repeat all the operations until the front snow cutter-blower is discharged. Then go back and continue the work cycle until the snow is fully cleared.

If the last passage is made on a paved road the TF front snow cutter-blower must be set in floating mode.

4.Spreading operation 4.5.1 Clearing trenches It consists of a very thick snow layer located parallel to the ground. It is typical of roads bordered by the slopes of the mountains or tall trees.

The rules applied to the types of clearing already illustrated are valid, moreover:  You must know the exact location of the road and height of the snow to be removed (this value can be detected from the positions and height of the signalling stakes).  Start the operations by calculating a clearing width sufficient to allow the residual mass of snow to have a foot support at the end of the operations, in order to prevent it from collapsing. Under these conditions, the front snow cutter-blower makes a snow cover of the "cuts" which may generate snowslides, especially if the operations take place during the spring. Therefore, have suitable emergency equipment available on the work site.

Fig. 9-4

 Proceed with the subsequent passages according to the above-mentioned technique.  Direct the chute downstream as the snow blown upstream may collapse on the road.

When the sides of the trenches are too high to be overtaken with the launch, direct the jet to the front and collect it with the front snow cutter-blower, as many times as required, in order to reach an area where side discharge is allowed.  The front snow cutter-blower must be on flat ground when working, therefore special attention must be paid to the side set-up of the vehicle; immediately correct any side leaning, resuming the operation from a precise point. The side inclination of the vehicle causes a load transfer to the wheels which is from where the leaning occurs. Consequently, the capability of the wheels to penetrate in the snow is increased thus enhancing the manoeuvre error (Fig.10-4).

Fig. 10-4

01/07/2016 Subject to technical modification

CAT194_Rev.00

PAG. 4-13

4.Spreading operation  Always remember that operations are made on an inconsistent ground and under poor adherence conditions. Therefore, the manoeuvres must be performed gradually to prevent the vehicle from stalling.

4.5.3 Clearing across a mountainside (Fig.11-4)

Fig. 11-4

This is the most difficult operation.

It consists of a very thick snow layer with a considerable inclination compared to the road profile.

This configuration is typical of the Alpine passes.

The rules applied to the previous techniques are valid also in this case.  Consider a large foot support for the upstream snow mass in order to prevent it from collapsing.  The personnel's safety is extremely important. Do not modify the transversal stability of wheel loader when working on inclined grounds. Always work on horizontal ground (Fig.12-4).

Fig.12-4

 Make sure that the cut does not cause detachment of snow and consequent avalanches (both for the downstream side and upstream side).  Direct the chute downstream as the snow blown upstream may collapse on the road.

Caution!

Remember that to increase adherence to the ground, the chains must be installed on the 4 wheels and under any clearing conditions.

PAG. 4-14

4.Spreading operation 4.6 Removing obstructions from the chute If cleaning operations are performed with excessive forwarding speed, it is possible that the turbine fails to process the snow, thus, obstructing the chute. Obstruction is also due to insufficient filling caused by slow activation in the event the snow is very wet, or due to the interruption of the power transmission caused by the failure of the shear bolt on the reducer, or activation of the pressure control valve in the hydraulic system after an impact against a foreign body.

Note: Obstructions of the chute due to excessive forwarding speed are often preceded by jet interruptions.

These can be avoided by immediately reducing the forwarding speed.

To remove any obstruction of the discharge chute, proceed as follows:  Switch the TF front snow cutter-blower off;  Stop the wheel loader;  Lift the the TF front snow cutter-blower;  Go back with wheel loader in reverse gear in order to have sufficient space in the TF front snow cutter-blower and ensure safety while working;  Lower the front snow cutter-blower;  Turn the chute backwards to set it in oscillation position;  Switch the wheel loader engine off;  Remove safety plug R and remove the fixing pin;  Rotate the chute downwards and take the supplied rod;  Remove as much snow as possible from the turbine by making the snow softer with the rod and, if possible, rotating the augers against the forwarding;  Push the snow with the rod from the top using the chute to melt the compact snow;  Remove as much snow as possible from the chute;  Set the chute back to work position, fix it with the specific pin and connect the safety plug;;  Start the engine and switch the front snow cutter-blower on. Now, slowly increase the activation speed until the residual snow is removed.

Danger!

Never use your feet or hands when removing obstructions from the chute!

Danger!

Never work with reclined chute. The snow blow is uncontrolled and can be dangerous for the operators.

Danger!

Never climb on the front snow cutter-blower when removing obstructions from the chute - risk of falling.

Pay attention that people or objects are not hit by the snow when works are resumed.
