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
