1. Transport & handling
1.1 Transport
The floor grinder is delivered mounted on a pallet wrapped in protective packaging
with the following dimensions: 120 x 80 x 120 cm. During transport, the handle is
(see fig 2.1 no. 11) "bent in".
1.2 Handling
The floor grinder can easily be transported on the pallet on which it is delivered.
The pallet has strips attached near the two aluminium wheels that prevent the
floor grinder from running. Remove the floor grinder from the pallet. Then it can be
lifted down from the pallet.
During transport it should be checked that the grinding belt has not been in
contact with the underlay and that it rotates freely. See fig 2.1: the weight of floor
grinder should be on the transport wheel (no. 10) when the belt grinder is not in
use. This can be attended to by adjusting the height of the transport wheel (No. 2)
and the grind adjustment (No. 4).
1.3 Connection
The electrical connection and the power on/off switch are on the handle (see fig
2.1 no. 1 and 8). The 4.1 and 5.6 kW motor is equipped with a motor protection
device and zero voltage release for direct connection to 3 x 400 / 415 V or 3 x 230
V, 50 / 60 Hz. Connection should only be made with a shorter cable (minimum
wire gauge 1.5 mm²) with a plug connection, whereby a total electrical cut-off is
possible.
The machine is equipped with a switch with a 0 voltage relay and connected to the
desired voltage (V). The electrical connection must be performed by an authorized
fitter. It must be checked that the motor (and any fan) has the correct direction of
rotation (see the arrow on the motor).
1.4 Belt Adjustment
Before grinding begins, it should be checked that the belt grinder runs correctly
when idling. This means that the belt is not in contact with the floor. Lift the belt off
the floor by loosening the height adjustment of the transport wheel (See fig. 2.1
no. 2). When starting the machine, it is possible that the belt will run crooked. This
can be adjusted with the adjustment handle no. 6 (see fig. 2.1) as follows:
•clockwise - the belt runs to the left
•counter-clockwise - the belt runs to the right
1.5 Fastening the Handle
Upon receipt, the handle can turn freely around the shaft. Tighten the two
Unbrako screws near the shaft so that the handle is at the working height, which
the operator desires.
2. Directions
After the above connection and belt adjustment, the floor grinder is ready for use.
Each time you start a new surface, you have the option of adjusting the grinding

5
height or the thickness of the grind and tip of the belt/grinder. The belt grinds near
the contact disc (3). The lifetime of a new grinding belt is increased if you start
with light grinding pressure. This is done by starting the machine without the
machine touching the underlay, and then you can carefully test whether the
grinding is correct or if you wish to change something. The height can be adjusted
while the machine is running, since you turn the grinding adjuster (4). If you want
to adjust the grinding tilt, it is recommended that you turn off the switch (8) and
then turn the tilt adjustment (9). This is because the machine can move by itself if
the contact wheel is touching the floor.
2.1 Floor Grinding
Start the belt by pushing the green button. The operator stands and holds the
handle (11). Avoid touching the grinding spot, since it will be hot during grinding.
Sparks are formed under the machine during grinding and flammable material
should not be near the grinding spot.

2.2 Belt Change / Correction of the Location of the Belt
If the belt has lost its ability to grind or is stuck, do the following:
1. Turn off the machine.
2. Make sure that the belt is not moving and that the contact wheel is not
touching anything.
3. Open the side cover that is sitting opposite of the belt release (7) by loosening
two Unbrako screws. Open the black top cover (5).
4. Loosen the belt by turning the belt release (7), and the grinding belt can now
be put in the correct position or be removed.
5. The belt can now be changed (the arrow on the belt must point in the direction
of rotation).
6. Tighten the belt again by returning the belt release, close the side cover and
now you can test it carefully. First using your hand and then by turning on the
machine briefly. You can adjust the belt sideways using the adjustment handle
(6). See also section 1.4 (Belt adjustment).
7. Then close the black top cover.
2.3 Maintenance
Clean as needed, perhaps with compressed air so that grinding dust is removed
from the contact wheel, drive wheel and other movable parts. Change the grinding
belt as needed, see the section on changing the belt. The contact wheel should be
changed if the edges have become rounded or if the track is defective.
2.4 Safety Rules for Stationary Power Tools.
Follow them to achieve best results and full benefit from your new machine.
The good craftsman respects
the tools with which he works.
He knows they represent years
of constantly improved design.
He also knows that they are
dangerous if misused.
This is the theme of a new safe-
use program for stationary
power tools. The safety rules
are based on approved
practices in industrial and home
shops
1. Know your power tool. Read the owner’s manual
carefully. Learn its applications and limitations, as
well as the specific
potential hazards
peculiar to this tool.
2. Keep guard in place
and in working order.
3. Ground all tools. If tool is equipped with three-
prong plug, it should be plugged into a three-hole
electrical receptacle. If an adapter is used to
accommodate a two-
prong receptacle, the
adapter wire must be
attached to a known
ground. Never
remove the third
prong.

7
4. Remove adjusting keys
and wrenches. Form
habit of checking to see
that keys and adjusting
wrenches is removed
before turning it on.
5. Cluttered areas and benches invite accidents.
6. Avoid dangerous
environment. Don’t use
power tools in damp or wet
locations or expose them to
rain. Keep your work area
well lighted.
6. Keep children away.
All visitors should be
kept in a safe distance
from work area.
8. Make workshop kid
proof with padlocks,
master switches, or by
removing starter keys.
9. Don’t force tool. It will
do the job better and be
safer at the rate for
which it was designed.
.
10. Use right tool.
Don’t force tool or
attachment to do
a job it was not
designed for.
11. Wear proper apparel. Wear no loose clothing,
gloves, neckties, rings,
bracelets, or other
jewellery which may get
caught in moving parts.
Non-slip footwear is
recommended. Wear
protective hair covering
to contain long hair.
12. Always use safety
glasses. Also use face or
dust mask if cutting
operation is dusty.
Everyday eyeglasses only
have impact resistant
lenses. They are NOT
safety glasses.
13. Secure works. Use
clamps or vice to hold
works, when practical. It’s
safer than using your
hands and it frees both
hands to operate tool.
14. Don’t
overreach.
Keep proper
footing and
balance at
all times.
15. Maintain tools with care. Keep tools sharp and
clean for best and safest
performance. Follow
instructions for lubricating
and changing accessories.

8
16. Disconnect tools before
servicing and when changing
accessories such as grinding
wheels, polishing mops,
grinding belts, blades, bits,
cutters, etc.
17. Reduce the risk of
unintentional starting.
Make sure switch is in off
position before plugging
in.
18. Use recommended accessories. Consult owner’s
manual for recommended accessories. Use of
improper accessories may cause risk of injury to
persons.
19. Do not work in a manner that can injure yourself.
Never work in a bent-over position. Stand up
straight. Alcohol and other drugs should not be
consumed while working.
