TECHNICAL DATA AND DESCRIPTION OF THE MACHINE
2.1. Description of the machine
The universal BS – 300R DiaKat grinder is designed for levelling of bumpy or uneven concrete and
asphalt horizontal surfaces, removing of paint, concrete blooming, dirt deposits, glue, horizontal road
markings and surface preparation prior to further treatment.
BS-300R is primarily intended for a “dry grinding” with the option of dust removing. However “wet”
grinding is also possible with the use of an auxiliary water tank.
The main drive spindle with the grinding tool is solidly mounted in to a rigid frame, which is lowered in
to the cut by means of hand operated setting wheels. In order to achieve deeper cut the machine can be
weighted by the means of additional weights placed on a holder situated above the main spindle. The
movement of the machine is achieved by the means of height adjustable cushioned handlebars.
The grinder is powered by single cylinder four stroke HONDA 8,1 kW petrol engine.

!ATTENTION! Always follow the instructions below when mounting or dismounting tool! (Only then
you can set up the machine with tool correctly and safely.) The machine must be always
secured against movement and the engine switched off when changing tool!
2.5.1. Mounting of tool
1. Bring the machine to standstill and secure it by rising the Quick-lift.
2. Remove all additional weights and water tank.
3. Use the rear setting wheel to rise the machine to the maximum height. (The restrictor chain is taut.)
4. Lift the machine by its front wheel and tilt it over the rear wheels until it rests on the handlebars.
5. Secure the machine against toppling.
6. Do not leave the machine in this position longer than necessary for changing the tool!
7. Set the tool with its collar in to the hole of the tool carrier; align the screw holes in the tool with the
threaded holes in the carrier.
8. Hold the tool on the carrier and secure it with three high tensile screws with CSK head.
9. Tighten the screws on rota basis.
10. Make sure that the tool collar fit fully in to the hole of the carrier.
2.5.2. Dismounting of tool
Similarly dismount the tool.
3. BEFORE STARTING
3.1. Visual check up of the machine state
Regularly (before commencing work) check:
•all covers and safety features
•all screwed joints
•sealing of fuel and lubrication system
•oil level (see engine manual)
•cleanness of air filter (see engine manual)
•fuel level (HONDA– Natural 95)
•state of tool’s wear

4. WORKING WITH THE MACHINE
4.1. Setting of the machine , start
!ATTENTION! never start the engine if the tool is touching the floor.
1. With the aid of front and rear setting wheels set the machine that the tool (machine frame) is
parallel to the working surface and the tool is lightly touching the floor.
2. Set the depth of cut by the front setting wheel and tighten the check nut. By using the rear setting
wheel again level the machine. Lock the rear setting wheel.
3. Rise the machine by means of the Quick-lift.
4. If necessary put on the additional weights.
5. Start the engine (see engine manual).
6. When max. revs are reached slowly lower the machine using the Quick-lift leaver.
4.2. Working with the machine
If all settings are correct the machine is moving over the surface easily. If the engine is choking it will
be necessary to readjust the depth of cut or discard some of the additional weights.
In order to achieve the best flatness of the grounded surface move the machine evenly from side to
side and at the same time move slowly forward.
Regularly check the state of wear of the grinding tool and clogging by dirt of the TCT cutters!
Clogged tool can not work properly, it wears unevenly and clogging can eventually lead to damage or
destruction of carrier and cutters.
4.3. Switching off the machine
1. Rise the machine by means of the Quick-lift leaver.
2. Pull the throttle leaver to “0” position.
3. Switch of the machine by the red Emergency stop button.
4. Close the fuel line!

5. MAINTENANCE
The basic steps of preventive maintenance described in this manual can be carried out by the operator
appointed by the entrepreneur. We recommend that all repairs and adjustments beyond the scope of this
manual are carried out by authorised service centre.
!ATTENTION! In the guarantee period it is prohibited to interfere with the engine and power
transmitting components in any manner whatsoever!
!ATTENTION ! It is prohibited to change the rev setting in any way!
5.1. Cleaning of the machine
Regular cleaning prolong the life of the machine its components and tools. After finishing work clean
the machine from dust and dirt by wet cloth or air before storing. Never use pressurised water for
cleaning.
5.2. Checking screw joints
Check the tightness of screw joints before every start of the machine. Regularly check the tightness of
the tool securing screws.
5.3. Engine maintenance
See engine manual.
5.4. Tool maintenance
Regularly check the wear and soiling of tools. If the diamond segments are almost worn off, change the
tool. If the TCT cutters are clogged with dust and dirt and can not rotate freely loosen them by light
taping of the hammer and pressurised air.
5.5. Inspection of tautness of V belts.
Regularly check the tautness of the V belts. The deflection of the V belt under the pressure of an index
finger should be approximately 20 mm.
If the v belts needed to be drawn tauter proceed as follows:
1. Dismount the bottom V belts cover.
2. Loosen the 4 M12 nuts holding the engine base.
2. Draw the V belts tauter by means of the tensioning bolts that the deflection is circa 20 mm.
3. Retighten all joints and remount the cover
