3 Operation

EN Floor grinding machine DSM 530S / DSM 650S / DSM 800S
Risk of damage due to tensile strain exerted
by the power line!
The electric outlet serving as the power sup-
ply should be supported and installed ac-
cording to local regulations.
Risk of injury from inadvertent starting of
the machine!
Before plugging in the power plug, make
sure the machine is switched off!
Risk of damage and injury from uncontrolled
driving the machine!
Before switching on, the machine has to be
held firmly by the guide handle of the guide
bar.
10. Turn the FWD/0/REV rotary switch [18, Fig. B]
to 0 (the middle position).
11. Join the connecting cable (extension cable) with
the proper power socket and plug the connec-
tion cable's coupling in the power plug
[4, Fig. A].
The indicator lamp DUTY [19, Fig. B] lights up.
The machine is ready for operation.

3.2 Operating hours counter

The machine is equipped with an operating hours
counter [13, Fig. B].
3.3 Operation
The FWD/0/REV rotary switch [18, Fig. B] is set
to 0 (the middle position).
1. After wet grinding, the water supply or the ma-
nual valve needs to be opened or closed accor-
ding to the amount of water necessary, (based
on experience).
2. Hold the machine by the guide handle [1, Fig. A]
3. If necessary, press the safety cap [17, Fig. B/D]
on the safety switch until it snaps in.
4. Sling the safety line [20, Fig. D] around the wrist
so that if the operator departs the guide handle,
it is assured that the safety cap will be separa-
ted from the safety switch.
The surface to be ground can now be machined.
5. Select the rotation direction with the
FWD/0/REV rotary switch [18, Fig. B].
18
— FWD (forward):
The gears turn anticlockwise; the ETX lo-
cating plates turn clockwise.
— REV (backwards):
The gears turn clockwise; the ETX locating
plates turn anticlockwise.
All specifications on the direction of rotation are
to be considered as seen from above the ma-
chine.
Many tools with polycrystal diamonds
(PKD) [26, Fig. I] only permit use in one rota-
tional direction.
Tools with metal- or synthetic bonded dia-
monds [27/28, Fig. I] may be used in any ro-
tational direction.
Clogged tools with metal or synthetic resin--bon-
ded diamonds [27/28, Fig. I] can reattain the full
grinding effect by changing the direction of rota-
tion.
6. The drive is switched on and accelerates to the
speed set at the SPEED regulator [16, Fig. B].
7. If necessary, use the SPEED regulator to adjust
the speed for the grinding conditions.
If surface mills are being used, do not allow
the set (SPEED) to exceed max. 50%!

3.4 Switching the machine off

Follow the safety instructions in Chapter 2.
Risk of injury from a still rotating ETX loca-
ting plate even after the machine is switched
off!
Only switch off the machine with the tools
resting on the floor.
Otherwise, the tool mount can continue to
turn in idle (run--on) for several seconds after
switch off!
— Turn FWD/0/REV rotary switch [18, Fig. B] to 0.
The machine is switched off
In an emergency, the machine can be swit-
ched off with the EMERGENCY-STOP button
[14, Fig. B] or by pulling off the safety cap
[17, Fig. B].
High voltage, danger of injury!
There is still residual voltage even after the
machine has been switched off.
In order to switch the machine free of vol-
tage, the power plug [4, Fig. A] has to be di-
sconnected from the mains!
