2. Move the accelerator lever into the front position (CHOKE). Start the engine by pulling
on the manual starter (instructions for starting see the guidelines for engine use).
3. Let the new or cold engine running for about 30 seconds on the choke (accelerator lever
in the CHOKE position); then move the accelerator lever into the position MAX and let
the engine running in this position for about 30 seconds.
,Don’t leave the machine alone when doing this.
6.3 Starting the mowing disk
,When starting the engine, the two levers on the handlebars must be in the off
position.
1. Start the engine. When doing this, follow the instructions presented in the operating
manual for engine use.
2. Set-up maximum engine rotations by accelerator lever on the right handrail. (Should the
engine be cold, let it warm up at maximum speed for about 1 minute.)
3. Grasp the left handlebar grip. Then slowly press the mowing disk drive gear lever on the
right handlebar grip with your right hand.
,Press the lever slowly up to two thirds of the stroke so that the mowing disk can
start rotating and the engine does not stall.
The start of the mowing disk is accompanied with a partial slippage of the V-belt and
with the related phenomena such as whistling, rattling, etc. which usually disappear after the
belt has started properly moving.
4. After the mowing disk has started turning, press the lever completely to the handrail and
hold firm.
Note: In a new or cold engine, engine stalling may occur at several first mowing disk
drive starts. The phenomenon will disappear after the engine has got warmer. If the disk
drive cannot be started even after the engine has got warm, follow the table presented in
chapter 7.6 for diagnostics.
6.4 Machine travel
The travel gear is to be switched on by a lever on the left handrail. Press the lever down
to the handrail and the machine starts immediately moving forward. You have to start slowly
walking as soon as you have pressed the lever down and the machine has started its travel.
,The machine may start moving with a slight jerk; be prepared for that.

6.5 Machine stop
,Prior to performing any activities in the near vicinity of the machine, switch off the
engine and wait until the mowing disk stops! Always switch the engine off before
leaving the machine.
,Never let the engine running at maximum speed or idling with the mowing disk
drive gear clutch released and with the released clutch of travel wheels drive gear
for a long time! Machine drive components (V-belt, belt pulley, clutch pulley, etc.)
might get damaged!
If you wish to stop the machine travel, release the lever on the left handlebar grip. The
machine travel will stop but the mowing disk is still rotating. The mowing disk drive will
switch off immediately after you have released the lever on the right handlebar grip. The
mowing disk will be stopped by safety brake.
Engine is to be switched off by pushing the lever into the STOP position.
,In the case of any critical situation, release your hold on the handlebars
immediately. The levers will return to their zero position, the machine and the
mowing disk will come to a stop (while engine is still running at adjusted rotations;
this is why it is to be switched off by pushing the lever into the STOP position as
soon as possible!)
6.6 Working with the machine
6.6.1 Working engagement 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, avoid working the
places.
,Mowing engagement width has to be at all times accommodated to stand density!
On the upper surface of the apron, there is a
yellow strip placed on the right side to indicate
the maximum working engagement of the
mowing disk on the right. Edge of the to-be-
mown stand should not exceed the boundary
given by the strip (see Figure).
Warning: When mowing, make sure that the
lower disk is permanently pushed against the
Strip on the apron

ground and does not rebound. Disk rebounding results in uneven stand mowing
6.6.2 Mowing grass stands
Set the engine to maximum speed, let the mowing disk rotate at maximum speed
(starting the mowing disk see chapter 6.3) and get the machine into motion (see chapter 6.4)
facing the stand to be cut. The mown grass is thrown away by the mowing disk to the right
side onto the screen which forms a swath. Grass leaves the space under the screen from in
front of the right wheel.
The only correct way how to proceed at cutting the grass stand is to have the to-
be-mown grass at all times on the left side of the machine (see Figure).
It is adviseable to drive the machine along the slope contour lines for cutting.
Keep in mind, however, that the maximum machine tilt permitted is 20° (long-term)
and 30° (short-term)!
If the stand is very dense, grown through, rotten or lodged, the machine working
engagement width must be reduced accordingly so that the mowing disk rotations are not
being excessively reduced and the cutting quality impaired.
6.6.3 Problems at cutting
Choking of the space under the upper casing and apron with grass can show as follows:
a) Engine markedly loosing speed but not stalling: machine travel to be switched off
immediately (lever on the left handrail); drive in reverse gear just a bit with a
simultaneous slight lifting of the machine front (by pushing down on the handlebar
handrails). The casing space will do itself a partial clearance of excessive grass matter.
Then drive the machine against the stand again (see chapter 6.4).
,Be very careful while lifting the machine and at reverse driving!
b) Engine loosing speed and stalling: release the both levers on the handlebars, lift the
machine front part by pushing down on the handlebars and drive a bit in reverse. Clear
the space under the upper casing and spread the cut grass across the ground. Start the
engine, switch on the mowing disk drive (see chapter 6.3) and once again drive the
machine against the stand (see chapter 6.4).
,The engine must always be switched off when clearing the space under the upper
casing and screen!
,Tilt the machine always only backwards onto the handlebars. Be very careful while
moving in the space beneath the lifted machine! Secure the machine against
spontaneous motion!
,Be very careful while cleaning the space under the upper casing and screen. Cutting
edges of knives are sharp. You should wear protective gloves or you can also use a
piece of branch etc.

7Maintenance, care and storage
To ensure a long-term satisfaction with our product, it must be 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 adjustment. It is adviced
that you keep records on the number of machine working hours and on the conditions in
which the machine was working (for service purposes). Similarly as the current maintenance,
the post-season maintenance should be entrusted to one of our authorized service workshops
if you are not certain of your own technical skill.
,Regarding the machine weight, its maintenance and adjustment are to be made by a
team of two persons.
7.1 Machine lubrication
7.1.1 Gear oil replacement and refilling
,When replacing oils, follow the basic hygienic principles, regulations and laws
on environment protection.
The gearing works in an oil bath. Oil condition should be checked once a month (oil
plugs see Fig. 4).
Minimum grade of gear oil according to API should be GL-4, GL-5; according to SAE:
90 or 80W-90.
Oil replacement in a new machine is to be made after the first 5 hours of operation and
then after 100 working hours or after the season. This will ensure that the gears will not
suffer excessive wear. The exchange interval can be extended up to 130 hours (the running-
in time of 5 hours must be adhered to) in higher oil grades (API GL-5, SAE 80W-90).
Czech oils fully meeting the requirements are MOGUL TRANS 90 or MOGUL TRANS
80W-90.
Oil replacement should be made when the gearbox is warm, oil can be drained easily.
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 box and the drain plug in the bottom of
the gearbox (spanner No. 19).
3. After the oil has been drained, screw back the drain plug in the bottom of the box. Fill the
gearbox with the new oil (it is adviced to use a funnel with flexible tubing). Oil level
should reach to the lower edge of the hole. Then screw the pour-in plug back. If the seals
under the plugs are damaged, replace them with new ones.

BDR-595 E EuroAdela

7.1.2 Engine oil replacement
See the guidelines for engine operation. To drain the oil, the machine should be either
inclined onto the side with the pour-in neck with oil gauge, or the engine should be
dismounted from the machine (see chapter 7.4 a,b,d).

fastening the knives in the upper disk and bolts fastening the lower disk onto the flange prior
to any machine use.
7.3 Replacement and sharpening of working knives
If the cutting edges of working knives show wear or a damage to knives results in
machine vibrations, the cutting edges must be renewed or the knives replaced.
,The machine must be standing on a firm support plate and must be secured so that
the knife can be easily accessible and an unexpected spontaneous machine motion
cannot occur.
,Be very careful when dismounting the knives. 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!

2. Hold the upper disk so that it does not turn and dismount the knife bolted connection by
using the barrel spanner No. 16 and flat wrench No. 17.
3. Take the knife and parts of knife seating out of the mowing disk. Level the blade and
sharpen the knife cutting edges. Inclination of the sharpened blade should be 30° with
respect to the lower plane of the knife.
,Should some of knives be bent or showing a considerable wear, you must always
replace all knives in the mowing disk!
4. Screw back the bolt with the filler, knife and flat washer. Than screw on the nut.
5. Hold the bolt head with the barrel spanner No. 16 and tighten the nut. All knives must
freely rotate on the bolts. The knives have blades on both sides; when one side is worn
out, the knife can be reversed and the blade of the other side can be used. When replacing
the knife, replace also all damaged parts of the knife clamping (see Fig. 6).
Note: Manufacturer does not answer for damages caused by the machine if the knives
were repaired by unskilled persons without the use of the original spare parts. There is a
“VARI“ stamp on the knife, which identifies the manufacturer and is at the same time a
control mark indicating that the knife is an original spare part.
7.4 V-belt replacement and adjustment of tightening pulley
The V-belt should be replaced according to its wear (cracked sides, torn belt, sides worn
out down to belt carrier fibres, belt pulled out of shape) or after about 100 hours of operation
at the maximum. In this machine, the belt stretched to maximum is considered a belt in which
the distance between the internal belt surfaces is lesser than 7 mm (with the pressed lever of
mowing disk drive clutch) – see Fig. 7.
