TECHNICAL DATA AND DESCRIPTION OF THE MACHINE
2.1. Description of the machine
The BL-300 DiaKat Floor Grinder is designed for grinding small bumps and slight unevenness of
horizontal floor areas. It find its widest use in grinding and levelling of smaller concrete, anhydride and
screeded floor areas with diamond or Tc tipped grinding tools The BL -300 is primarily intended for a
“dry grinding” with the option of dust removing.
The grinder is powered by 3,2 kW Honda petrol engine. The engine is mounted on a rigid frame and is
connected to the drive spindle by means of a flexible ring coupling. This configuration enables the tool
to cope with floor unevenness and ensures smooth transfer of torque. The undercarriage consist of
height adjustable rear wheels, with which the depth of cut can de adjusted and an adjustable front wheel
with which the depth of cut can be restricted. The front wheel also provides easier transport. The
machine is manipulated by means of adjustable handlebars.

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 (especially tool mounting screws)
•state of tool’s wear
4. WORKING WITH THE MACHINE
!ATTENTION! Always use adequate dust collector when grinding in enclosed area.
4.1. Setting of the machine , start, stop
!ATTENTION! never start the machine 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. Set the machine to idle position by quick-lift controller so that the tool is in safe height above the
ground.
4. Start-up the engine.
5. When reaching maximal engine RPM’s lower the tool carefully on the ground.
6. According to the type of grinded material and requested pressure add corresponding additional
weights (always same qty on each side of the machine) so that engine’s RPM are sustained during
work.
!ATTENTION! Select such a depth of cut (depending on the material grinded) so that the machine is
not overloaded (the motor must not slow down or stall – danger of damage to the motor).
4.2. Working with the machine
If all settings are correct the machine is moving over the surface easily. In order to achieve the best
flatness of the grounded surface move the machine evenly from side to side in arches 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.

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. 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.
5.4. Engine maintenance
Follow the manual for Honda petrol engine!
