Introduction and Description
This manual is intended to provide operation and service information required
for the safe and efficient use of the K-Kub Floor Grinder.
Operating or servicing the unit other than in accordance with the instruction
given in the manual may result in subjecting the machine to conditions beyond
its capability, which may result in the failure of the machine or personal injury
to the operator.
IMPORTANT:
•Read the operating manual and warranty conditions given before
attempting to operate the floor grinder. Special attention must be
given to the section entitled “Safety Precautions.”
The K-Kub Floor Grinder is a sturdy, reliable and easy to use machine.
The K-Kub Floor Grinder is fitted with 2.2kW single phase motor. This motor
offers direct drive to the grinding plate with the incorporation of a flexible
coupling between the motor and the plate.
The K-Kub shroud system is unique in design, automatically adjusting to suit
segment height and floor angle. This shroud system when used in conjunction
with an appropriate industrial vacuum unit eliminates dust loss during
grinding. The shroud has 2 removable sections to enable the operator to grind
close up to the wall etc. Please note dust loss is possible when this section is
removed.
The K-Kub comes complete with a water connection for wet grinding should
this be required. There is also a ball valve which allows the operator to
regulate the water supply to obtain the best grinding results.
The K-Kub has a foldable handle which makes it easily transportable in any
small vehicle. The rear wheels can be extended outwards should the operator
require more stability from the grinder. This requires the use of an 8mm Allen
key. The operator can also raise and lower the height of the handle to
maximise their comfort during their use of the grinder.

Operation
The K-Kub is designed to be used either for wet or dry floor grinding. If the
floor that has to be ground is dry ensure a suitable industrial vacuum is
connected and also ensure the operator is wearing suitable breathing
respiratory equipment. Contact your local work place health authority to
ensure that their requirements regarding respiratory equipment are being
met.
Starting the Grinder
1. Check the grinding plate being used is suitable for the material being
ground and THAT THEY ARE CORRECTLY BALANCED.
2. Check that the grinding plates used are in good order and are properly
attached, with all countersunk bolts firmly in place. Check this
occasionally during use, as they can become loose during working.
3. Check that the grinding plate is adjusted so that it sits level on the
ground.
4. Check all nuts and bolts on folding handle latch are tight and firm.
5. Raise the grinding plates from the floor.
6. Start the motor by pressing the Green switch on the starter box.
7. Lower the grinding plate and commence grinding.

Safety Precautions
The K-Kub floor grinder has been designed to minimise noise and vibration
levels and to provide maximum safety to the operator. However, incorrect use
of the grinder may cause serious injury to the operator hence the following
precautions must be taken.
1. Do not use the grinder for longer than prescribed in your local
environment working regulations, as the noise load from extensive daily
use may result in hearing defects.
2. Always use protective earplugs or earmuffs, goggles, gloves and
protective footwear.
3. Do not modify the grinder in any manner, or use a machine that has
been modified by anyone other than the manufacturer or authorised
dealers.
4. Do not add weight to the machine to make the grinder work harder.
Instead reduce the number of segments on the grinding plates to
increase the performance.
5. Make sure that re-tipped plates and new grinding plates are balanced
properly.
6. Do not run the grinder with the grinding head raised higher than
necessary, i.e. tipped back on the handle.
7. Always make sure that the folding handle latch is secure and has not
vibrated loose after use.
8. When grinding the machine is exposed to high vibration. Occasionally
check the machine if any nut or bolt has loosened due to the vibration.
9. Do not allow water or cotton to enter the interior of the motor.

Maintenance
Daily cleaning: The motor in use should always be kept clean. No water
droplets, cotton etc should be allowed to get into the interior of the motors.
Check on load current: While the motor is in operation, constant care should
be taken to keep the load current below the rated value.
Running sound: During the operation of the motor there must be no rubbing
noise shrike or other random noise. Stop the motor immediately and restart
after the corrections have been made.
Check the folding handle latch periodically. This is adjustable. To adjust loosen
the lock nut on the latch and then screw in the treaded paw until a satisfactory
tension has been achieved.
The wheel bearing are sealed type so they do not require regular greasing.
**NB to minimize vibrations and uneven blade wear, rotate plate every 2
hours.
Failure to do so can lead to premature wear of the flexible coupling.
