Electric Floor
Grinder
An electrically powered grinding
machine for removing surface
imperfections, sealants and mastics
from concrete slabs.
Operating & Safety Guide 453
Please note that strip-serts are not suitable for use
on wet surfaces.
Gently lower the machine back onto its wheels
and check that it is level. If the grinder is not level,
or the wheels are left in the transport position,
attempting to use it will damage your floor.
You MUST use either water or dust extraction
to
comply with health and safety regulations.
For wet grinding attach a water hose to the water
inlet
at the rear of the machine.
Do not allow water
to flow until you are ready to start work.
Water supply hoses and suitable wet pick up vacuum
cleaners are available for hire from your local HSS Hire Shop.
For dry grinding attach a dust extraction unit to
the dust extraction port
at the rear of the machine.
Dust extraction units are available for hire from your local
HSS Hire Shop.
Position the grinder at the start of the work
and
uncoil the power supply cable.
All that remains is to
plug the Floor Grinder into its
power supply and switch the supply ON.
Always
position yourself so you can control the
Floor Grinder while staying clear of the grinding
head.
When wet grinding, turn the water supply on at
the tap and open the water inlet valve on the
machine.
Only use enough water to reduce dust as
excess water can create a hazardous working area and
will cause clean up problems.
When dry grinding switch on the dust extraction
system.
Keeping one hand on the control handle, tilt the
machine back
, enough to raise the inserts off the floor
and switch the machine ON by moving the
ON/OFF switch to the ON position.
Gently lower the machine to the floor. On first
contact with the surface the machine may jolt,
use
extra care until you are familiar with this characteristic.
When grinding, work in straight, overlapping
strips until the entire area has been covered. Do
not pause in one spot or you will damage the floor.
Take your time and don’t over do it.
You are more
likely to have an accident if you are tired or rushing.
When you have finished, tilt the machine back
to
raise the inserts from the floor
and switch the unit OFF
by moving the ON/OFF switch to the OFF
position.
When the grinding head has come to a rest lower
the machine back to the floor.
BASIC TECHNIQUES
When wet grinding, close the water inlet valve
on
the machine
and turn the water supply off at the
tap.
When dry grinding, turn the dust extraction
unit off.
Never push the equipment beyond its design
limits.
If it will not do what you want with reasonable
ease and speed, assume you have the wrong tool for the
job. Contact your local HSS Hire Shop for advice.
Replace the inserts as soon as they become worn
.
Use only inserts supplied by HSS, any others could
damage the machine and your floor.
Keep the equipment clean
- you will find this less of a
chore if you clean it regularly, rather than wait until the
end of the hire period.
When not in use
, store the equipment somewhere
clean, dry and safe
from thieves.
Switch OFF and unplug the floor grinder.
If dry grinding detach the extraction hose from the
machine and coil it away.
If wet grinding detach the water hose from the
machine and coil it away.
Remove any inserts fitted to the grinding head,
then neatly coil the power supply cable and give
the machine a final clean up ready for return
, to
your local HSS Hire Shop.
FINISHING OFF
Cutter Replacement
Strip-sert cutters have four sides and can be
rotated as sharpness deteriorates.
Using an allen key undo the cutter retaining
screw. Rotate the cutter to present a sharp
edge. When all four edged are blunt replace
with a new cutter. Use only cutters supplied
by HSS, any others could damage the machine
or your floor.
