10. OPERATION
10.1 OPTIMUM OPERATING CONDITIONS TO CONSERVE THE BATTERY CAPACITY
10.1.1 RECOMMENDED SPEEDS
When working with the loader with the basic shovel, we recommend setting the machine to slow speed (tortoise). For fine
handling of heavy objects when loading or unloading, slow speed is also recommended. For other types of work with the
loader, the settings must be made and adjusted according to the type of task at hand. As a rule, when working with the
loader, the lower the speed, the more substantial the savings on battery capacity. A higher speed (hare) is recommended
when travelling with the machine over longer distances.
10.1.2 DRIVING STYLE
The battery capacity is also significantly affected by the actual driving style. As far as the situation allows it, it is recommended
to turn with the machine in a style around the entire radius, that is, with the track on one side of the loader not moving,
or moving at low speed, and rotating on the other side of the machine. In this way, the loader turns economically. It is
uneconomical to turn around the axis, which is with the tracks on each side moving in the opposite direction from the other
side. This will result in a sharp drop in battery capacity.
10.1.3 SURFACE
The surface on which the loader operates also affects the battery capacity greatly. The loader has rough-terrain tracks
mounted as a factory standard, specifically tracks with a sparse and high tread pattern. However, this track is not suitable
for tarmac or concrete as it is soft, has great rolling resistance and it slips. Where the machine is expected to operate mostly
on paved surfaces such as tarmac or concrete, it is recommended to equip the loader with tracks for paved surfaces to
avoid heavy strain on the battery and severe wear of the tracks.
!
There must be no unsealed openings in the cabin. Sealing the openings with plugs does not provide an additional barrier
to gas leakage.
Caution
Risk of damage to components!
A deformed or damaged battery plug may cause overheating and subsequent damage.
Danger of explosion if hydrogen accumulates inside the loader
Hydrogen from the battery compartment may enter the loader through unsealed openings in
the cabin.
Accumulated hydrogen may cause an explosion.
Danger
Distractions while working with the machine may result in loss of control over the machine.
Exercise extreme caution when using any devices while working with the machine. Distractions
while working with the machine may result in injury or death.
Danger
A machine fire can cause injury or death. Exposed battery cables that come into contact with a
grounded connection may cause a fire. Replace cables and similar components that show signs
of wear or damage. Contact the manufacturer.
10.2 BASIC INSTRUCTIONS FOR CORRECT USE OF THE CHARGING EQUIPMENT
1. Before connecting the battery to the charger, check the integrity of the contacts, connecting cables, connectors and auxiliary
systems.
2. Connect the battery to the charger, observing the correct polarity.
3. The batteries may only be connected to designated chargers approved for the type concerned.
4. Observe the full charging time, i.e. until the full charge indication on the charger.
5. Charging starts automatically once the connectors are mutually engaged.
6. Disengage the connectors in the off state (when not energized) – press the STOP button.
7. Replenish the distilled water in the battery each time it is charged. In the event of water losses and leakage when
replenishing, report this to service.
8. Read the instructions for using the assigned equipment carefully and thoroughly.
9. Report any damage to or malfunction of the charging equipment to your supervisor and service.
OPERATION
$Connect the power cord to the 230 V AC mains.
$Use cables to connect the battery to the charger and check that the polarity is not reversed.
$Check that the four LEDs light up in sequence. This confirms that the device is receiving power and that the LEDs
are working properly (automatic diagnostic test).
$When the battery is properly connected and the charger is not in autostart mode, the DL1 LED is lit (signal
battery is connected).
$To start the charging process, press the P1 button on the front panel.
$If the autostart function is on, the charger starts charging five seconds after the battery is connected (signalled
by flashing DL3 and DL4 LEDs).
$In the event of a power failure, the charging process stops and the card switches off; after a power failure restart,
the card is reset and the charging process starts from the beginning.
$When the battery is connected, the charging process is interrupted. After the battery is reconnected, the charger
can continue with the charging process (the SW1.6 switch is off), or starts it again from the beginning (SW1.6).
$Please note that in order to avoid electric sparks, do not disconnect the batteries during the charging process.
After connecting the battery, start the charging process with the ON/OFF button.

16. CLASSIFICATION OF ROCKS
Rocks are classified into seven classes according to the difficulty of separating and removing them. These classes are
called mining classes (this is an excerpt from the standard; the exact wording is given in ČSN 733050).
16.1. CLASS 1
a) cohesive with a soft consistency (topsoil, loam, loamy sand, etc.);
b) non-cohesive, loose with a grain size up to 20 mm;
$with a grain size over 20 mm in up to 10% of the volume of the rock to be separated (sand, medium gravel, gravel
with stone).
16.2. CLASS 2
a) cohesive with a hard consistency (topsoil, loam, loamy sand, peat);
b) non-cohesive, moderately compacted with a grain size up to 20 mm;
$with a grain size from 20 to 50 mm in more than 10% of the volume of the rock to be separated;
$with a grain size above 50 mm in up to 10% of the volume of the rock to be separated (sand gravel, coarse gravel,
or gravel with stone);
c) construction waste and landfill materials similar in nature to Class 2 rocks.
16.3. CLASS 3
a) cohesive with a soft to firm consistency;
b) non-cohesive, compacted with a grain size up to 50 mm;
$with a grain size from 50 to 100 mm in more than 10% of the volume of the rock to be separated;
$with a grain size over 100 mm in up to 10% of the volume of the rock to be separated (coarse gravel, or gravel with stone);
c) non-cohesive, classified in Classes 2 and 3, held together by a cohesive material, as far as the grains remain in lumps
after separation;
d) weathered with very weakened structural bonds, qualifying as clay-sand soils (hydrothermally decomposed rocks, eluvial
deposits);
c) construction waste and landfill materials similar in nature to Class 3 rocks.
16.4. CLASS 4
a) cohesive with a firm and hard consistency (clay, sandy clay, sandy loam, dust loam);
b) non-cohesive with a grain size from 100 to 250 mm in more than 10% up to 50% of the volume of the rock to be separated,
with a grain size above 250 mm in up to 10% of the volume of the rock to be separated (coarse gravel, gravel with boulders)
c) non-cohesive, classified in Classes 2 and 3, held together by a cohesive material, as far as the grains remain in lumps
after separation;
d) solid, slightly weathered and weathered (weathered claystones, marlstones, tuffs, turiffs, slates, etc.), weathered slates,
sandstones, soft limestones, etc.;
e) solid, weathered, severely cracked. The rock is disturbed along the cracks and its disintegration spreads into neighbouring
areas. The grain size corresponds to non-cohesive Class 4 rocks (highly cracked granites, gneisses and limestones);
f) slurry and liquid in consistency (muddy alluvium, liquid sand, decomposed peat).
16.5. CLASS 5
a) non-cohesive with a grain size from 100 to 250 mm in more than 50% of the volume of the rock to be separated, with a
grain size above 250 mm up to 0.1 m3individually in more than 10% up to 50% of the volume of the rock to be separated
(coarse gravel with stone/boulders);
b) non-cohesive, classified in Class 4, held together by a cohesive material with Class 4 properties, as far as the grains
remain in lumps after separation (coarse gravel with clay-loam bonding material);
c) solid, healthy, in layers up to 150 mm thick (conglomerate with clay bonding material, slate, travertine, sandy marlstone, etc.);
d) solid, igneous, sedimentary, weathered and cracked with areas of divisibility of less than 150 mm (weathered granite,
gneiss, andesite, sandstone, quartz);
e) landfill materials similar in nature to Class 5 rocks;
f) frozen soils.
16.6. CLASS 6
a) non-cohesive with boulders from 250 mm up to 0.1 m3individually in more than 50% of the volume of the rock to be
separated, with boulders above 0.1 m3individually in up to 50% of the volume of the rock to be separated;
b) solid, igneous and metamorphic rocks, healthy with areas of divisibility up to 1.0 m in bench block separation. Crack
distances less than 250 mm (granite, gneiss, andesite, basalt, slate, phyllite);
c) firmly sedimented, healthy with a distance of divisible surfaces up to 1.0 m. Other crack distances of up to 250 mm –
coarsely bench-shaped (coarsely fragmentary to boulder conglomerates and agglomerates with calcareous and marly
bonding material, limestones, dolomite, etc.).
16.7. CLASS 7
a) non-cohesive with a grain size over 0.1 m3individually in more than 50% of the volume of the rock to be separated;
b) solid, healthy, massive, or with irregular spherical, columnar detachment with individual wedges, with areas of divisibility
greater than 250 mm (quartz, silica granite, gneiss, basalt, andesite, veined quartz, cherty limestones, diorites).
Abbreviated characteristics of the mining classes according to the ways in which rocks can be separated:
Class 1 - loose rocks that can be picked up with a shovel/with a loader;
Class 2 - excavatable rocks, separable with a spade/with a loader;
Class 3 - diggable rocks, separable with a pickaxe/with an excavator;
Class 4 - crumbly solid rocks, separable with a wedge/with an excavator;
Class 5 - solid rocks that are easily broken up and separable with a ripper/heavy excavator (over 40 tons) or with explosives;
Class 6 - solid rocks that are difficult to break up with a heavy ripper or with explosives;
Class 7 - solid rocks that are very difficult to break up, separable with explosives.

17. PREVENTIVE MAINTENANCE
Maintenance is important and is the best protection against premature wear of the unit assemblies. Perform the prescribed
work tasks to prevent possible malfunctions. In regular checks and inspections, it is possible to detect wear and malfunction,
and failures can be prevented by cleaning and lubricating, tightening loose connections, removing leaks, etc.
Maintenance includes the following work tasks:
cleaning and care, recharging the battery, topping up lubricating greases, changing oils, checking all units, adjusting,
checking mechanical joints and their tightening, etc.
For a better overview, we have included all maintenance work tasks in tables according to the number of operating
hours worked. Read the number of operating hours on the control panel located in the cabin. Keep a record of the
maintenance work tasks carried out in the machine’s warranty book. Maintenance is divided according to the inspection
and maintenance schedule.
The following common rules apply to all disassembly and assembly procedures:
$Use the most suitable tools that do not damage the nuts or bolt heads.
$Components that move relative to each other when assembled are not mounted dry. They need to be lubricated
with a lubricant designated for the respective component in service.
$When assembling preserved components, the preservative grease must be removed and replaced with operating lubricant.
$Replace defective components only with original parts.

17.3 DESCRIPTION OF MAINTENANCE ACTIVITIES
17.3.1 OIL CHANGE IN THE HYDRAULIC SYSTEM
Drain the oil by unscrewing the plug at the bottom edge of the hydraulic tank.
When changing the oil, observe maximum cleanliness. Fill with new oil through a filter with an efficiency of 10 µm. The
correct oil level is indicated by the position of the oil mark on the tank. Move the work device a little so that the oil fills the
entire system. Refill the tank again with oil to half the height of the oil mark.
To extend the service life of the loader units, take a sample of the hydraulic oil in the amount of 0.5 litres every 1000 OH.
Take the sample into a clean glass container when the oil is heated to approx. 50 °C. If the oil that is removed is thickened
and dirty compared to new oil, it must be changed or the change intervals shortened. Use only oil specified in the machine’s
operating and maintenance manual! When changing hydraulic oil, always replace the hydraulic oil filter as well.
17.3.2 MAINTENANCE OF HYDRAULIC CYLINDERS
Make sure that in operation, the bearings of the cylinder attachment lugs are sufficiently lubricated and the wiper ring on
the cylinder cap wipes dirt from the piston rod over the entire stroke range. In the event of a leak, it must be replaced to
prevent damage to the sleeve and subsequent oil leakage around the piston rod.
17.3.3 CHECKING AND TENSIONING TRACKS
In operation, regularly monitor the condition (wear, tensioning) of the tracks. Replace damaged tracks in good time.
Proceed carefully when tensioning, and observe the prescribed tension value.
17.3.4 CHECKING AND TIGHTENING TRAVEL WHEELS
Check the tightening of the wheel nuts according to the inspection and maintenance schedule of the machine. The
tightening torque is 100 Nm.
17.3.5 CHANGING OIL IN GEARBOXES
1. Turn on the machine and make a trip to warm up the oil. After a short drive, the oil temperature will rise. Once the oil is
warmed up enough, it will be less viscous and much easier to drain.
2. Locate the drain plug, found on the side of the gearbox. Rotate the gearbox so that the drain plug points downwards.
3. Remove the drain plug and allow oil to drain into the prepared container. Four to five minutes should be sufficient to
completely drain the used oil. Repeat the procedure for the other gearboxes as well.
4. Check that the drain plug is not damaged and screw it back on securely. Be careful not to tighten it excessively.
5. Release the filler cap found on the side of the gearbox and fill with oil using a funnel. To reach the required level, 0.4
litres of oil are needed. Tighten the cap correctly and firmly. Repeat the procedure for the other gearboxes as well.
6. Finally, dispose of the used oil properly. Use any container that can be closed tight and take the used oil to a
designated place, collection point or landfill.

17.3.6 MAINTENANCE OF THE LOADER’S ELECTRICAL EQUIPMENT
Caution
For the proper functioning of the entire electrical equipment, properly charged and maintained
batteries are the most important factor.
Maintain the correct electrolyte level by topping up with distilled water each time you charge.
Caution
At the end of work or a drive, and always when the loader will not be used for a longer period of
time, disconnect the battery by disengaging the battery connector. The batteries must also be
disconnected during repairs or when replacing parts of the electrical equipment. This will prevent
a short circuit in the power line during the installation works. Battery maintenance includes
cleaning the terminals, topping up with distilled water and recharging. At lower air temperatures,
keep the batteries sufficiently charged, as otherwise they are not frost-resistant and may freeze.
If you do not use the battery for a longer period of time, you must recharge and carry out
maintenance on it after four to six weeks. Clean the battery terminals of deposits with hot water
and lubricate them lightly with grease. The service life of batteries lasts longer the more often
they operate, i.e. are alternately charged and discharged.
