Use i Overview DRIVING TIPS AND INFORMATION 100-11547.en 109/126 DRIVING TIPS AND INFORMATION SNOW TYPES In the atmosphere, snow forms from water droplets at temperatures of at least – 4 ° C. Ice crystals in widely varying shapes form: Hailstones are snow crystals enlarged by the adhesion of ice; they are usually spherical or tapered in shape. Hoarfrost or rime forms from water vapour or precipitation on chilled objects (fences, bushes, surface of snow). White frost develops when the wind carries chilled droplets of water onto solid objects. Always work so as to cause as little damage as possible to the snow. The aggressive action of driven implements such as a tiller damages the snow crystals; these damaged crystals have lost their ability to mesh as a loose blanket, tending instead to ball and form gritty snow (often at entrances to garages, approaches to lifts, bottlenecks). Preparing fresh-fallen snow Fresh-fallen/ powdery snow consists of crystals that are loosely attached to each other and which therefore trap a great deal of air. The process of preparation inevitably expels some of this air and packs the crystals more tightly together. This gives the surface layer of snow the ability to bear weight. Fresh-fallen snow initially forms an airy structure of loosely intermeshed snowflakes. The original shapes soon disappear, however, and the individual flakes are no longer recognisable only a few days after falling. 110/126 100-11547.en Overview DRIVING TIPS AND INFORMATION Over a period of time skiers break down the topmost layer – humps and hollows form and the run becomes bumpy. Iced slopes/ sheets of ice The teeth of the tiller break the lumps down into gritty snow, which fills the hollows in the surface of the run; the finisher shapes the surface and a water film forms to hold the grains of gritty snow together. Breaking down the lumpy snow also damages the ice crystals, so they lose a considerable proportion of their ability to cohere. This is the reason why only gritty snow, not powdery snow, can be produced from ice. 100-11547.en Checks If outdoor temperatures are correspondingly low the snow freezes and forms lumps - when this happens the only way of making a ski run look well is to work with a tiller mounted on the rear of the vehicle. Do not break up an iced slope unless the ice is of adequate thickness or fresh snow falls. The gritty snow produced by breaking up the ice needs fresh-fallen snow to cohere, or else it will cohere with water - and this will again cause ice to form. Consequently, it is advisable only to roughen the surface of the ice to make the slope skiable. Sheets of ice on slopes that are otherwise in good condition can be broken up and mixed with crystals from deeper in the snow. The more frequently the ice is turned and the crystals damaged, the less will be their ability to cohere. Operation Preparing slopes like this is a process in which old snow is mixed with relatively fresh-fallen snow (snow crystals) and this produces a durable surface. Safety A durable ski slope can be formed only by mixing this material with fresh-fallen snow or with unused old snow from deeper levels. Use The friction of skis over the surface causes some of the crystals to melt and form a film of water, and this produces sheets of ice and the softer spots beside them. Technical data Bumpy runs 111/126 DRIVING TIPS AND INFORMATION Wet snow/slushy snow The relatively large amounts of moisture and the formation of a film of water on the finisher can produce a relatively hard surface, which inexperienced skiers in particular find difficult. Allow the snow to set-up, so that crystals can form. In order to counteract this effect, Kässbohrer has developed a bolt mechanism for tilting the rear-mounted tiller comb. In combination with special finishers, this machine can change the uniform surface structure and produce a "powdery-snow" effect. Extremely slushy snow in spring It is advisable to use the side wings, because the tiller can produce edge walls as it passes through the snow. Kässbohrer also offers an extra-wide side wing for more efficiency when used in combination with the rear frame steering – this also means that the machine can prepare on one side at a time. If a satisfactory run cannot be prepared in slushy snow, is might be advisable to wait two or three hours to allow the temperatures to change. Work on preparing slopes at higher altitudes can proceed in the interim. 112/126 100-11547.en Overview DRIVING TIPS AND INFORMATION S = Centre of gravity Safety Inexperienced drivers, in particular, should familiarise themselves with the vehicle and equipment before undertaking operations in difficult terrain. Use The climbing ability of the PistenBully depends on the limit of adhesion of the snow. The machine's centre of gravity is another factor influencing climbing ability. It is important for the driver to ensure that as much of the surface area of the tracks as possible is in contact with the ground, as otherwise there is a risk of the vehicle toppling. The limits are heavily dependent on the way in which the vehicle is used, on load, on the prevailing conditions, and on the skill and ability of the driver. Technical data CLIMBING ABILITY Each situation must be assessed with care. Never assume that it is safe to operate in a certain area at any given time merely because a vehicle was in the area in question beforehand. . 100-11547.en Operation Checks H = Downgrade force 113/126 DRIVING TIPS AND INFORMATION DRIVING WITH THE PISTENBULLY The basic rule is: Do not use the vehicle until the snow is deep enough to prevent damage to the underlying vegetation. The objective in preparing a ski-slope is to achieve visually excellent slope quality: Build up supplies of snow in good time at critical points, so that reserves will be available to make up for the snow removed from the slope. Holes and snow heaped up by movement and by manoeuvring must be smoothed out with as little delay as possible. If speed is excessive, the tracks will throw snow out sideways and over the auxiliary mounted implement onto the prepared surface. Regularly remove snow from the load platform. Otherwise, the increase in weight will result in higher fuel consumption. Always keep the engine revving in the most economical range (indicated by the green zone on the tachometer). The drive electronics adjust speed to suit engine rpm. Driving: On upgrades Always study upgrades and look for the easiest route; do not start at the steepest point. Frequently, it is better to detour to the highest point of a slope via an alternative route and then work from the top down to prepare the first part of the run. Whenever possible, negotiate slopes by following the line of fall and by keeping steering movements to a minimum. Do not overrev the engine: use only as much power as is necessary; note the level of traction. Overrevving will cause the tracks to slip, with the result that the vehicle will dig into the snow. If the tracks start to dig in stop immediately and try a different line. Digging in ruins the ski-slope and destroys the surface beneath the snow. 114/126 100-11547.en In order to avoid damaging the surface of the ski-slope, you must turn at or beyond the edge of the prepared slope. You should, of course, use areas that are free of vegetation (forestry plantations and the like) for this purpose. Restrict your steering movements to a minimum. Make sure that both tracks are turning. Reduce speed as you crest rises, in order to ensure that you have the vehicle under control as it tips forward. This will prevent the front blade from digging in and the tracks from losing traction. Driving: On downgrades Always maintain a moderate speed on downgrades. This precaution will enable you to ensure that the engine does not overrev, the vehicle does not drift out of control and the snow is not dragged downhill by the action of the tracks. Use the track-speed potentiometer to reduce the speed of 100-11547.en - the adhesion of the snow is adequate. - your run out at the bottom of the slope is adequate and safe. Use You can turn the vehicle in its own length by counter-rotating the tracks. This causes the vehicle to dig in to some extent, so you should manoeuvre in this way only when the snow is of adequate depth. It is advisable to employ this method of turning in exceptional situations only. Turning with counterrotating tracks places very high strains on the rubber belts and the track cleats. - there are no skiers in the danger zone. If the PistenBully starts slipping on a downgrade and drifts at an angle to left or right (vehicle's longitudinal axis is at an angle to the line of fall), you must immediately apply opposite lock (turning the steering wheel to the right or left, as applicable), counter-rotating the tracks if necessary, in order to bring the vehicle's longitudinal axis back onto the line of fall. Briefly increase engine speed in the process. You can counteract slippage along the line of fall by reversing the tiller shaft's direction of rotation and carefully employing the front blade to re-stabilise the vehicle. Checks Turning with counter-rotating tracks Invariably, do not negotiate a downgrade unless you are sure that: Safety PAlways Operation keep the front-mounted and rear-mounted auxiliary driven implements raised when turning. descent. Technical data Turning Overview DRIVING TIPS AND INFORMATION 115/126 DRIVING TIPS AND INFORMATION PREPARING THE SKI-SLOPE When preparing a slope, always make sure that the side finishers overlap onto the prepared surface, in order to ensure a smooth transition from one pass to the next. Notes on depth of tiller The tiller has to be set to the correct depth in order to: O Achieve a visually attractive ski-slope. O Retain the firmness of the slope's substructure. O Operate within the most economical range. O Apply least load to the PistenBully and the tiller. Effects of incorrectly set tiller depth: O Tiller shaft too high: Tiller quality output is negligible. O Slope is not contoured in areas of hard snow. O Tiller shaft too low: Insufficient snow processing, so the snow is forced out of the tiller at the side and forms an edge wall. O O The snow crystals' ability to cohere and the quality of the slope's substructure are impaired. More power input necessary – less economical. Counter-rotating tiller shaft A PistenBully with electronic tiller control enables you to set the tiller to rotate either forward (standard direction) or backward. It can be helpful to have the tiller counter-rotate, for example as an additional brake in very steep terrain. Errors in operation and counter measures Summarised countermeasures Edge walls forming on left and right: O Speed of rotation too high. O Tiller set too low. O Downforce setting selected instead of floating setting. O Cylinder of carrier plate incorrectly adjusted. O Tiller shafts not rotating. 116/126 100-11547.en Overview DRIVING TIPS AND INFORMATION Tiller set too high (adjust height setting). O Speed of rotation too low. O Lever not locked in position (floating position). O Vehicle travelling too fast. O No smooth surface with the U-shaped pusher blade (rotary plough is on a hump). Safety O Technical data Visual appearance of prepared slope not satisfactory Tiller too low. O Speed of rotation too high. O Cylinder of carrier plate inadvertently out of adjustment. O Tiller shafts are counter-rotating. O Tiller shafts stopped – clogged, jammed, frozen. O Shaft imbalanced, tooth missing – have repairs carried out by specialists. O O Frozen snow – remove. Imbalance means vibration – screws work loose, bearings are damaged – have the imbalance rectified. 100-11547.en Operation O Severe vibrations perceptible in vehicle when the tiller is switched on Checks O Use Vehicle comes almost to a stop: 117/126 FRONT BLADE preparation. It is ideal for smoothing bumpy runs and dozing snow clear. The front blade is also very useful for working uphill through freshfallen snow and it can be used as a brake to prevent the vehicle from slipping. Consequently, it is advisable to leave the front blade installed at all times. Smoothing bumpy ski slopes Applications: O Use of the front blade on steep slopes covered with freshfallen snow O Smoothing heavily worn ski slopes O Smoothing bumpy ski slopes O Making a location line Material wear due to load. During dozing work (i.e. when pushing snow with the front blade), fully raise rear carrier plate. A front blade is essential for modern ski-slope upkeep and The best method of smoothing low bumps or waves is to use the front blade in what is known as the "floating" position. This means that the front blade applies only its own weight to the surface, without being pushed downward by the hydraulics. The blade's angle of attack is set by means of the roll cylinder. Exercise great care when setting the roll cylinder, because if the angle of attack is too steep the front blade will tend to dig into the snow. Approach large bumps with the blade at approximately half height and the float function switched off, so that the blade will push the snow forward off the bump and into the hollow on the other side. In this case, too, it is best to use the roll cylinder to adjust the depth of cut, instead of raising and lowering the 118/126 100-11547.en Making a location line The best way of doing this is to approach the downslope at an angle from above and, with the pusher blade swivelled to one side, doze a flat location line in the snow. It is advisable to start with no more than a small amount of snow, picking up more and more snow as you proceed along the line. This should enable you to complete the full length in a single run. The snow you push out on the downhill side inevitably widens your location line, increasing the margin of safety. Smoothing heavily worn ski slopes One consequence of modern skiing techniques is that the skiers carry the snow progressively further down the slope, finally depositing it toward the bottom of the slope. The objective, therefore, is to restore the snow to as uniform a depth as possible over the entire length of the slope. This entails pushing the snow back up the slope from the bottom. If necessary, winch the PistenBully into position. Pivot the front blade to an angle at which the snow can slide along it toward the inside. If you are using a 12-way front blade 100-11547.en Safety Use The ideal configuration is to have a leader snow roller mounted in front of the blade, as this will enable the equipment to adjust automatically to compensate for surface irregularities. When you prepare fresh-fallen snow you need the front blade not only to push the snow, but also to distribute the weight and apply pressure to the surface of the snow. You can use the front blade to help the vehicle climb steep slopes by stopping just before the PistenBully digs in, and reversing with the front blade lowered. This will smooth out the step. Raise the front blade and drive forward a few meters before repeating the procedure; this is one way of climbing difficult slopes. Checks Use of the front blade on steep slopes covered with fresh-fallen snow Operation front blade. This is the most dependable way of smoothing out the slope. Technical data Overview FRONT BLADE 119/126 FRONT BLADE you can set the wings to an angle that best suits this method of handling the snow. The front blade can be adjusted in a number of ways to the position that best suits the terrain. The end result is efficient transportation of the snow to the parts of the slope where it is needed. Less experienced drivers in particular should bear in mind that transporting large amounts of snow quickly is not always the way to achieve the best results. The driver has to assess the terrain and decide whether it would be advisable to push snow downhill, or whether this might result in even more snow being lost. The correct position of the compactor bar also depends on the conditions of the snow. A well-prepared slope is free of heaps of snow, does not have walls along the edges, and is contoured so as to be attractive to the eye. 120/126 100-11547.en On account of the quick-change design, the tiller can be removed and installed by one person working without assistance. Intended use of the tiller: O Compressing wet snow. O Preparing glacier ice (in summer). Adjusting tiller depth PPress the pushbutton for adjusting tiller depth to lift the tiller completely clear of the surface. Only the finisher of the tiller is resting on the surface of the snow. the tiller up to medium speed and set the vehicle in motion. Technical data Mixing freshly fallen snow through old snow. Safety O PRun PGradually Use The tiller has hydrostatic drive and is used to loosen compacted snow on much-used slopes, for breaking up lumps of hard snow and ice, and for mixing fresh snow through old snow. The height of the tiller shaft can be adjusted hydraulically from the cockpit, and the shafts can rotate forward or counterrotate. The two shafts are easy to change and can be removed and replaced with other types of shaft when snow conditions change. Overview TILLER lower the tiller shaft with the vehicle on the O O Reworking slopes covered with freshly fallen snow. Smoothing humpy slopes (in combination with front blade). O Roughing up icy slopes. O Breaking up hard lumps of snow. O Breaking up and mixing sheets of ice. 100-11547.en The tiller depth is correct when the slope behind the finisher has a good appearance. Operation Use of the tiller is permissible, given an adequate depth of snow, for: Checks move. 121/126 TILLER When ascending, always set the tiller shaft to forward operation and use a suitable working speed until the ski slope has been prepared to specification. An attempt to operate the rotary plough at too high a speed will divert too much power from the engine, with the result that the engine will not be able to develop enough power to propel the PistenBully. When descending extremely steep gradients, the tiller shaft can be set to counter-rotate so as to help stabilise the PistenBully. 122/126 100-11547.en INDEX Nummer 12-volt socket .................................................................48 3.
