MANUAL
INTRODUCTION AND DESCRIPTION
This manual is intended to provide operation and service information necessary
for the safe and e󰀩cient use of the Tool-Co BDG250 Floor Grinder.
Operating or servicing the unit other than in accordance with the instructions
given may subject the machine to conditions beyond its capability, which may
result in machine failure or personal injury.
IMPORTANT
Read the entire operating manual carefully before attempting to use
the oor grinder. Special attention should be paid to the section titled
‘Safety Precautions’.
The oor grinder is a sturdy, reliable and easy to use machine.
The oor grinder is tted with a 2.2kW single phase motor. This motor o󰀨ers
a direct drive to the grinding plate with the incorporation of a exible coupling
between the motor and the plate.
The shroud system is unique in design, automatically adjusting to suit segment
height and oor angle. This shroud system, when used in conjunction with an
appropriate industrial vacuum unit, eliminates dust loss during grinding. The
shroud has two removable sections to enable the operator to grind close up to
the wall etc. Please note that dust loss is possible when this section is removed.
The oor grinder comes complete with a water connection for wet grinding
should this be required. This incorporates a ball valve allowing the operator to
regulate the water supply to obtain the best grinding results.
The oor grinder has a foldable handle which enables it to be easily transported
in the trunk of most small vehicles. The rear wheels can also be extended
outward should the operator want more stability from the grinder. This requires
the use of an 8mm Allan Key. The operator can also raise or lower the height
of the handle to maximize their comfort when using the grinder, and the new
designed lifter system makes operator handy to use.

SAFETY PRECAUTIONS
The oor grinder has been designed to minimize noise and vibration levels and
to provide maximum operator safety. However, incorrect use of the grinder may
cause serious injury and therefore the following precautions must be taken:
1. Do not use the grinder for longer than prescribed in your local environmental
working regulations, as the noise load from extensive daily use may result in
hearing defects.
2. Always use protective earplugs or earmu󰀨s, goggles, gloves and correct
footwear.
3. Do not modify the grinder in any manner, or use a machine that has been
modied by anyone other than the manufacturer or authorised dealer.
4. Do not add weight to the machine to make the grinder work harder.
5. Reduce the number of segments on the grinding plate to increase performance.
6. Be sure that re-tipped and new grinding plates are properly balanced.
7. Do not run the grinder with grinding head raised any higher than necessary, i.e
tipped back on handle.
8. Always be sure that folding handle latch is secure and has not vibrated loose
after use.
9. When grinding, the machine is exposed to high vibration. Occasionally check
machine for bolts/nuts which may have vibrated loose.
10. Do not allow water or cotton to enter the interior of the motor.

MANUAL
OPERATION
The oor grinder is designed to be used either wet or dry. If the oor is being
ground dry, ensure a suitable industrial vacuum is connected and that 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 being used are in good order and properly
attached, with all countersunk bolts rmly in place. Check this occasionally
during use, as they can work loose during operation.
3. Check that the grinding plate is adjusted so that it sits level on the ground.
4. Check that all nuts and bolts on the folding handle latch are tight and rm.
5. Raise the grinding plates from the oor.
6. Start the motor by pressing the black switch on the starter box.
7. Lower the grinding plate and commence grinding.
STOPPING THE GRINDER
1. De-press the red stop button on the starter box.
NOTE:
1. By turning and pushing the handles, you can x the vertical grinding position.
2. Adjust the axle’s width to improve grinding stability.

MAINTENANCE
Daily cleaning: The motor in use should always be kept clean. No water, or debris
should be allowed to get into the interior of the motor.
Check on load current: While the motor is in operation, constant care should be taken
to keep the load current below the maximum recommended motor current rating.
Operational sounds: During operation of the motor there must be no rubbing sounds,
shrieks or other random noises. Stop the motor immediately and restart after
inspection and corrections have been made.
Check folding handle latch periodically. This is adjustable. To adjust, loosen the lock
nut on the latch and then screw in until a satisfactory tension has been
achieved.
The wheel bearings use sealed bearings and require no regular greasing.
*NB To minimize vibration and uneven blade wear, rotate plate every 2 hours.
Failure to do so can lead to premature wear of the exible coupling.*
**Ensure all re-tipped and new grinding plates are properly balanced.**
FAULT DIAGNOSIS
Symptom Possible Cause Action
Machine will not start
No power is available. Check that the power cable
is plugged in / switched on.
Machine is trying to start on
glue or sticky substance.
Clear a patch with scraper
