Area of use

Tandem vibration rollers of the VH 850/VH 950 series are the machines with backbone frame, with two steel smooth drums. Both drum are hydrostaticaly driven, oscillatory and controllable, when each of these functions is independently selectable. Independent electrical-hydraulic drums driving enables to set the extended track (crabing).

The frame and cab conception enables the compaction close to the curbs or walls, when the swivel driver’s working place enables good control of the machine driving at both directions. The weight distribution to the front and rear drum and also the equal centrifugal power of the front and rear vibrator prevent making the track in the compacted surface when using the crab drive. Ergonomically designed cab can be, including the protective frame ROPS, tilt by the hydraulic means for simplification the access to the drive aggregate.

The vibration rollers of the VH 850/VH 950 series are designed for compaction works of the middle and extended scope in the area of road engineering (building of highways and roads, airport areas) and ground engineering (industry areas and so on).

The rollers can be used for compaction of asphalt compositions to the layer thickness (after compaction) of 140 mm (5,5 in), hydraulic cemented compositions to the layer thickness of 250 mm (9,8 in), composed earth to the layer thickness of 300 mm (11,8 in), sand and gravel materials to the layer thickness of 400 mm (15,7 in).

The rollers are not convenient for compaction of rockfill, aluminous and clayey materials.

The machines of these series are engineered for operations under the conditions due to the CSN IEC 721-2-1 (038900) : WT, WDr, MWDr (i.e. temper climate zone, hot dry zone or warm dry zone with limited temperature scope from –15 °C (5 °F) to +45 °C (113 °F) of ambient temperature.)

OPERATING INSTRUCTIONS 2.8.10. Driving with vibrations on compacted and hard material When driving with vibrations, contact of drums with compacted material can worsen or be lost (so called vibrouder) due to high level of compactness of the subgrade or due to driving with vibrations on hard material. This situation results in increased transmission of vibrations to the machine frame and the driver’s stand. Partially, it can be reduced by increasing the travel speed. While subgrade material gets more compacted, transmission of vibrations to the driver’s stand can be expected, too.

2.8.11. Compacting near buildings If compacting near buildings or utility lines and cables cannot be avoided, it is necessary to examine influence of the machine vibrations to these buildings or lines and cables so as to protect them from damage.

The manufacturer of the machine cannot be held responsible for damages caused by using the machine near buildings or underground utility lines.

If working with the machine under conditions exposing the operator to increased vibrations cannot be avoided, the keeper of the machine must modify working procedures so that it is not harmful to the driver’s health.

It is not allowed to work on a long-term basis in the ”vibrouder” mode. In the extreme, the machine may be damaged.

• In the position II., the machine sprinkles all the time also on the place and the pumps run constantly.

Signaling of the failure of spraying:

• The failure of the spraying of drums is signaled by interrupted lighting of red pilot lights (47) for the front drum and (48) for the back drum and by interrupted audible warning of the horn located in the control panel.

• From time to time, a unique and short-term signaling of the failure can occur, that stops in the next cycle. In such case it is not a failure of pumps neither shortage of water in sprinkling tanks.

! NOTE !

If the emergency mode valve is not turned off and if both pumps operate, it is not a functional signaling of failures in the system!

Turning the spraying failure signaling off:

• Signaling of the failure can be canceled after stopping the machine by switching the sprinkling switch (46) over to the position 0 and afterwards the switch (46) switch over back to the position I. or II. and the error will not be signaled anymore.

Check of the sprinkling function:

• Check the function of sprinkling prior to work commencement – check spraying of both the front and back tread.

• We recommend carrying out the check of the sprinkling function on the idle machine.

• The operator will adjust the position I. on the switch and he must slightly turn the potentiometer 4-5x for the machine to sprinkle in interrupted manner and he will monitor whether the error is announced. The interval of sprinkling for this check must be longer than 2 seconds.

• The other possibility of the check is an automatic check during the machine drive. The switch of sprinkling must be in the position I..

AIR CONDITIONER Descriptions

Main parts of air conditioning circuit

Heat is taken from the evaporator (5) placed inside the cabin (low-pressure circuit) and transmitted to ambient medium in the condenser (2) placed in front of the engine radiator (high-pressure circuit). The compressor (1) sucks coolant vapours from the evaporator and pushes them to the condenser (2). Coolant vapours change state (phase) from gas to liquid in the condenser and flow to thermoexpansion valve – TEV (4) - through filter-hydrator (3). The TEV (4) sprays the liquid coolant to the evaporator (5) where heat is taken from the cabin while the state changes from liquid to gas and coolant vapours are sucked to the compressor (1) again.

AIR CONDITIONER Maintenance Every month: • Check coolant fill visually while engine is running.

Keep eyesight glass clear. It must not be sweating or fogged, it must be free of bubbles.

Maintenance - according to conditions

• Clean condense gills by pressured air or pressured water. Choose the interval with regards to dust conditions on the worksite. Weekly cleaning is recommended.

• Clean evaporator gills with pressured air.

• Check tension of compressor belt. When pressing the belt in its longest part by force of approx. 3 N (1.5 lbf), slack must not exceed 10 - 15 mm (0.4 - 0.6 in).

• Check drain line of condensate from the evaporator clean it.

118

VH 850/VH 950

AIR CONDITIONER Troubleshooting Always contact a service provider to repair any defect!

Fault

Possible cause

The unit does not refrigerate

check evaporator fan - if not working, check fuse F12 (7.5 A) in fuse box check coolant fill in filter-hydrator eyesight for leakage of coolant (bubbles, fogging etc.) check switching of electro-magnetic clutch: turn on AC while engine is running - if the clutch does not switch (no click can be heard on compressor), faulty fuse F12 (7.5 A) fault in thermostat or faulty overpressure fuse

Safety Coolant is classified as safe; however, in case of leak to the atmosphere it will evaporate and contact with skin or mucosae will cause burns. If open flames are present, toxic gases may arise that would cause health risks or death in case of inhalation. In case of leaks in small restricted area, coolant vapours force out oxygen and may cause death by suffocation.

Always use safety goggles and gloves when working close to AC unit or directly on the unit.

Beware of injury caused by aluminium gills when cleaning them.

First aid in case of contact with coolant In case of eye injury caused by contact with coolant, rinse eyes with large amount of water and see medical assistance immediately.

In case of skin injury caused by contact with coolant, rinse the affected spot with large amount of warm water - not hot - immediately. Protect burns with dry sterile gauze. See medical assistance.

In case of inhalation, move the affected person to fresh air and restore respiration. Call medical assistance.

4.1.1.

Engine oil

Engine oil is specified after its power and viscosity classification.

Power classification according to API (AMERICAN PETROLEUM INSTITUTE) CCMC (COMMITEE of COMMON MARKET AUTOMOBILE CONSTRUCTORS).

ACEA (ASSOCIATION DES CONSTRUCTEURS EUROPÉENS DE AUTOMOBILE)

Viscosity classification SAE (Society of Automotive Engineers) viscosity class is based on ambient temperature and traffic pattern at the site where the machine is used.

Allowable oil application:

Viscosity diagram

API CH4/SG CCMC D5 All the year round SAE 15W-40, (e. g. Cummins Premium Blue).

NOTE When the lower temperature limit is exceeded no damage will occur in the engine; it may cause just some problems during start.

General multigrade oil should be used so that the oil exchange would not have to be made due to alterations in ambient temperature.

The engine manufacturer recommends SAE 10W-30 OIL as specified in the Diagram to facilitate starts at temperatures under 0 °C (32 °F).

! NOTICE !

Exceeding the upper temperature for a long time is not permitted because lubricating properties of the oil can get worse.

122

VH 850/VH 950

4.1.2.

Fuel

The following diesel fuel can be used in the engine: CEN EN 590 or DIN/EN 590 (suggested) DIN 51 601 BS 2869 (1988): A1 a A2 ASTM D 975-88: 1-D a 2-D VV-F-800C: DF-A, DF-1 a DF-2 NATO code F-54 a F-75

! NOTICE !

Common fuel for diesel engines contains less than 0.5 weight percentage of sulphur, if it has greater sulphur content of 0.5 to 1 %, the exchange intervals must be reduced to a half.

If outside temperature is less than 0 °C (32 °F), use winter diesel.

NOTE Sufficient frost resistance can be also achieved by using suitable additive to improve fluidity (fuel additive).

When using summer engine diesel at temperatures near 0 °C (32 °F), add paraffin oil to diesel to improve lowtemperature properties.

The diagram shows relationship between temperature and the amount of paraffin added.

! NOTE !

Mixing must be carried out in the tank only. First put the specified amount of paraffin oil into the tank, then fill with fuel.

Never used different fuel (e. g. biofuel, mixed biofuel, light fuel oils, and the like) than the above kinds of engine diesel.

Winter fuel mixtures are as inflammable as petrol – observe fire regulations!

Hydraulic oil

Only quality hydraulic oil having the power class as given in the standard No. ISO 6743/HV (corresponds to DIN 51524, Part 3 HVLP; CETOP RP 91 H) can be used for the hydraulic system of the machine.

The machines are as a rule filled by the manufacturer with hydraulic oil having kinematic viscosity of 68 mm 2/s at 40 °C (104 °F) ISO VG 68. Such oil is the most suitable for application on a large scale of ambient temperatures.

! NOTICE !

At high outside temperatures when oil temperature permanently reaches 90o C (194o F), oil having kinematic viscosity of 100 mm 2/s – HV 100 (BP BARTRAN HV 100; ESSO UNIVIS N 100, and the like) should be used.

If you have to start the machine at ambient temperatures lower than – 8 °C (18 °F) for a time period longer than one month, exchange the hydraulic system oil for one having kinematic viscosity of 46 mm 2/s – viscosity class HV 46.

At temperatures lower than – 13 °C (9 °C) exchange it for oil having kinematic viscosity of 32 mm 2 / s (e. g., BP BARTRAN HV 32; ESSO UNIVIS N 32, and the like).

Synthetic hydraulic oil The hydraulic system can be filled with synthetic oil, e. g. with PANOLIN – HLP Synth. 15/22/32/68 oil. If it leaks accidentally, it is completely degraded by micro-organisms occurring in the ground and water.

! NOTICE !

Water content in oil (condensed water) must not exceed the value of 0.1 %.

Service liquid must be checked by regular sampling in defined intervals – see the table.

PANOLIN HLP Synth oil must not be mixed with other biodegradable oils!”

When you fill elder machinery with PANOLIN HLP Synth oil, the remainder of mineral oils must not be greater than 8 % of the whole filling.

Use modified demineralized or distilled water for this mixture. The following table shows application with different content of ethylene glycol or propylene glycol in the cooling liquid: Ethylene glycol

Propylene glycol

40 % = -23 °C (-10 °F)

40 % = -21 °C (-6 °F)

50 % = -37 °C (-34 °F)

50 % = -33 °C (-27 °F)

60 % = -54 °C (-65 °F)

60 % = -49 °C (-56 °F)

68 % = -71 °C (-90 °F)

68 % = -63 °C (-82 °F)

! NOTE !

The proportion of the anti-freeze agent in the coolant should not be greater than 50 % if it is not absolutely necessary.

Never use greater portion than 68 %!

Anti-freeze agents should not be mixed together as anticorrosive properties could disappear after mixing different types of coolant.

Always check the portion of anti-freeze cooling agent in the coolant before winter season using refractometer (densimeter).

Harmful nitro-amines may emerge when an antifreeze agent based on nitrides is mixed with that based on amines.

When using a steam cleaner, do not expose electrical parts or insulation material to direct steam stream. Such materials should be always covered.

Take care not to splash water into the air filter.

Before cleaning the machine using pressure cleaners (water, steam, and the like), blind all holes through which the cleaning agent could penetrate (e. g. inlet hole of the engine, interior of the alternator, etc.). Remove these cappings after finishing the cleaning.

Disconnect the battery isolating switch!!

When cleaning, observe all ecological standards and regulations!

Carry out machine cleaning at sites where there are storage reservoirs for collecting rinse water and detergents.
