5.6 Working with the machine.
5 6 1 Working width of the machine
Prior to the machine use, the stand must be cleared of solid bodies such as stones,
wires, loose construction debris, etc , which could be flung or might otherwise
damage the machine Should these be impossible to remove, working of the places
should be avoided
Cutting width has to be at all times accommodated to the density of the stand!
Warning:
Particularly when cutting in uneven terrains,
make sure that the lower disk permanently
slides on the ground and does not re ound.
Disk re ounding results in poor stu le
quality and uneven stand cutting.
5 6 2 Cutting the stands
Set the engine on the maximum speed, let the cutting disk rotate at the maximum speed
(starting the cutting disk see Chapter 5.3) and then get the machine into motion (see Chapter
5.4), facing the stand to e cut. Cut grass or rushes are thrown away y the cutting disk to
the right side onto the side screen which forms a swath.
At cutting, you should proceed only in such a way that the to-be-cut stand is at all
times on the left side of the machine (see the picture).
At cutting on slopes it is advised to steer the machine along the slope contours Pay
attention to a maximum permissible long-term machine inclination of 20° (30° over a
short-term)!
If the cut stand is very dense, grown through, rotten from elow or lodged, the machine
working width must e reduced accordingly so that the cutting disk rotations are not
excessively reduced and the cutting quality impaired.
5 6 3 Problems at cutting
Choking of the cutting disk cover space with the cut material manifests as follows:
a) Engine markedly losing speed but not stalling: machine travel to e switched off
immediately (lever on the left handrail grip); move ackwards just a it with a simultaneous
slight lifting of the machine front ( y pushing down on the handle ar handrails). The space

under the cutting disk cover will do itself a partial clearance of the excessive grass and
de ris. Then drive the machine against the sward again (see Chapter 5.4).
Be very careful while lifting the machine and moving the machine backwards!
) Engine losing speed and stalling: release oth levers on the handle ars, lift the machine
front y pushing down on the handle ars and move the machine a it ackwards. Clear the
space under the cutting disk casing and spread the cut grass across the ground. Start the
engine, switch on the cutting disk drive (see Chapter 5.3) and once again drive the machine
against the sward (see Chapter 5.4).
The engine must be always switched off when clearing the space under the upper
casing!
Tilt the machine always only backwards onto the handlebars Be very careful while
moving under the lifted machine! Secure the machine against its spontaneous
motion!
Be very careful while cleaning the space under the cutting disk casing Cutting edges
of the blades are sharp You should wear protective gloves or use a suitable piece of
branch etc
6 Maintenance, care and storage.
To ensure a long-term satisfaction with our product, it must e given proper care and
maintenance. Regular maintenance of the machine will prevent its early wear ensuring at the
same time a correct functioning of all its parts.
Follow all instructions for intervals of machine maintenance and adjustments. It is
advised that you keep records on the num er of machine working hours and on the
conditions in which the machine was working (for service purposes). Similarly as the current
maintenance, the after-season maintenance of the machine should e entrusted to one of our
authorized service workshops in the case that you do not trust your own technical skills.
Regarding the machine weight, all maintenance and adjustment procedures are to
be done by two cooperating persons
6.1 Machine lubrication.
6 1 1 Gearbox oil replacement and refilling
When replacing oils, follow the basic hygienic principles, regulations and laws on
environment protection
The gearing works in an oil ath. Oil volume should e checked once a month (oil
plugs see Fig. 4).
Minimum grade of gear oil should e GL-4, GL-5 according to API, 90 or 80W – 90
according to SAE.
Oil replacement in a new machine is to e made after the first 5 hours of operation and
then after 100 working hours or after the end of the season. This will ensure that the gears

BDR-595 GMI Adela 190
15
will not suffer excessive wear. The exchange interval can e extended up to 130 hours with
oils of higher grades (API GL – 5, SAE 80W – 90). The running-up period of 5 hours must
e o served.
Czech oils fully meeting the requirements are MOGUL TRANS 90 or MOGUL TRANS
80W-90.
Oil replacement should e made when the ox is warm and oil is easy to drain.
1. Clean around the oil plugs. Underlay the machine and secure it so that a space is created
under the machine for a vessel to collect oil.
2. Loosen the pour-in plug on the rear wall of the ox and the drain plug in the ottom of
the gear ox (spanner No. 19).
3. After the oil has een drained, screw ack the drain plug in the ottom of the ox. Fill the
gear ox with the new oil (it is advised to use a funnel with flexi le tu ing). Oil level
should reach to the lower edge of the hole. Then screw the pour-in plug ack. If the seals
under the plugs are damaged, replace them with new ones.
6 1 2 Engine oil replacement
See the operating manual for engine. To drain oil, the machine should e either tilted
to the side with the pour-in neck with oil gauge, or the engine should e dismounted from
the machine (see Chapter 6.4, items a), ),d) ).

check the tightening of olts fastening the lades in the upper disk as well as the tightening of
olts fastening the lower disk onto the flange.
6.3 Replacement and sharpening the working blades.
If the cutting edges of working lades show wear or a damage to the lades results in
machine vi rations, the cutting edges must e renewed or the lades replaced.
The machine must be standing on a firm support plate and must be secured so that
the blade can be easily accessible and an unexpected spontaneous machine motion
cannot occur
Be very careful when dismounting the blades Their cutting edges are sharp Protect
your hands with working gloves
The engine must be switched off and the cable end connector to the spark plug
disconnected!
1. Hold the upper disk so that it does not turn and dismount the lade olted connection y
using arrel spanner No. 16 and flat wrench No. 17.
2. Take the lade and parts of the lade seating out of the cutting disk. Level and sharpen
the lade cutting edges. Inclination of the sharpened cutting edge should e 30° with
respect to the lower plane of the lade.
Should some of the blades be bent or showing a considerable wear, you must always
replace all blades in the cutting disk!
3. Screw ack the olt with the slid-on filler, lade and flat washer. Than screw on the nut.
4. Hold the olt head with arrel spanner No. 16 and firmly tighten the nut. All lades must
freely rotate on the olts. The lades are provided with cutting edges on oth sides; when
one side is worn out, the lade can e reversed and the cutting edge of the other side can
e used. When replacing the lade, all damaged parts of the lade clamping are to e
replaced, too (see Fig. 6).
NOTE: Manufacturer does not answer for damages caused during the machine operation
if the lades were repaired y unskilled persons without the use of the original spare parts.
There is a “VARI“ stamp on the lade, which identifies the manufacturer and is at the same
time a control mark indicating that the lade is an original spare part.

6.4 V-belt replacement and adjustment of tightening pulley.
V- elt should e replaced according to its wear (cracked sides, torn elt, sides worn out
down to elt carrier fi res, elt “pulled“ out of shape) or after a out 100 hours of operation at
the maximum. In this machine, the elt pulled out to maximum is considered a elt in which
distance etween inner elt surfaces (at the pressed lever of mowing disk drive clutch) is less
than 7 mm (see Fig. 7).
The replacement procedure is as follows:
a) Drain petrol from the engine tank. Dismount the accelerator lever (2x spanner No. 8)
from the handle ars. Bowden ca le should in no case e dismounted from the steering on
the engine!
) Unscrew three safety nuts (spanner No. 13) on the engine flange and pull the engine out
from the machine frame upwards. Never use force to pull the engine out from the frame!
Note: It is not advisable to dismount the engine together with the board which is
beneath it unless absolutely necessary If the engine board or gearbox disassembly
from the machine frame occurs, the reverse assembly must be made with a proper
axial alignment of the gearbox and engine shafts This is why the operation should
be made by an authorized service workshop which has to have available an original
and by manufacturer approved centring fixture

Never put the engine on the side Oil might get into the exhaust or into the air
cleaner Best engine placing is with the lower flange dwelling on two lintels which
are at least 7 cm high
c) Dismount the upper casing and handrail (flat wrenches No. 8, 10, 13). Dismount the
column in front of the driven elt pulley (see Fig. 5.3) (spanner No. 10). Take the old V-
elt off and replace it with a new one. Original V- elt marking is OPTIBELT
X13x1300Ld 6T6K (Ld=calculated length). It is also possi le to use an equivalent V- elt
made y other manufacturers at a size of A13x1270 Li (Li=internal length) or ½“ x
52“La (La=external length). However, the elt must e made without ru er on sides!
Only such a elt model will guarantee that the lade drive start is smooth at engaging the
clutch.
Should another than the above-mentioned original spare belt be used, the machine
manufacturer does not answer for correct and full functioning of the drive!
d) Put the engine ack in place. Pins in the driving elt pulley, installed on the engine, must
fall into holes in the ru er element on the driven part of the clutch. Bolt the engine with
three safety nuts with flat washers. Screw the accelerator lever ack onto the handle ars.
e) Put the V- elt into the groove in the elt pulley on the engine.
f) Check the operation of the tightening pulley and adjustment of guide lamination. With
the lever on the right handle ar grip fully pressed down, the pulley must ensure a
sufficient elt tension (spring on the ca le eing extended y a out 10 mm as compared
with loose condition). Possi le corrections are to e made y means of adjustment olt
No. 2 (see Fig. 8). With the lever switched off, the pulley must e tilted away from the
longitudinal machine axis at an angle of max. 0 - 5° = with the elt convex side eing
approx. 1.5 – 2.0 cm from the ottom of the tightening pulley (see Fig. 7). The ca le in
the Bowden of the tension pulley must exhi it no slackness. In the case that the
adjustment olt is completely screwed out and it is necessary to tighten the V- elt, the
spring on the ca le can e hooked into the front hole on the arm of the tightening pulley
(see Fig. 7 ottom, note: this connection can e used already from the manufacturer) and
elt tension can e adjusted once again. Guide lamination on the right side of the machine
must e parallel to the elt and at a maximum distance of 1 – 2 mm from the elt convex
side.
g) Mount the column ack to its original position in front of the driven elt pulley, mount
ack the upper plastic casing and the handrail.

6.5 Adjusting the wires of pulley, brake and wheel drive clutch.
In order to guarantee low operating forces on levers which control the drive switching, it
is advisa le to lu ricate the ca les in Bowdens at least 2x during the season with some of oils
availa le in atomiser (e.g. SILKAL, MD Spray, WD40). Correct functioning of the machine
also requires correct adjustment of drive controls.
Wire in the rake Bowden must always exhi it a slight slackness (with the lever of the
cutting disk drive clutch and rake released) so that the rake performance is sufficient. In
order to achieve clearance of the rake wire in the Bowden, adjustment olts have to e
screwed into the chassis or handle ars cross eam at the adjustment.
Wires in the pulley Bowden and in the Bowden of wheel drive clutch must e without
slackness, slightly tense. In order to make the wires tense, adjustment olts have to e
screwed out of the chassis or handle ars cross eam.
Safety nuts in all adjustment olts should e tightened y using two flat wrenches No. 10
or 9. If there is no more step to e used in the adjustment olt, it is possi le to displace the
hook on the wire into another hole in the sheet-metal lever on handle ars (or on the wheel
drive clutch lever on the gear ox and on the arm of the tightening pulley – see Figs. 7 and 8)
so that the initial tension of the wires can e again regulated y the adjustment olt.
