protective films. ake sure that the machine is not set up
or put into operation in a damp or wet environment.
The humidity should not exceed 60% and the measured
room temperature should be between 0 ° C and 40 ° C.
8.1 Fixing
Stationary use
For a safe footing, the machine should be mounted on a
stable base (such as a workbench) using the holes provi-
ded in the machine base.
Mobile use
For mobile use of your grinding machine, mounting on a
suitable base plate is recommended. This can then be
clamped on the respective workbench. The base plate
should be sufficiently stable and provide enough space
for the mounting clamps.
8.2 Electrical connection
When making electrical connections, make sure that the
characteristics (voltage, mains frequency, protection)
match those on the rating plate and for the motor.
Operate the Oscillating spindle sanding machine only on
an electrical supply, the following requirements
Fulfills:
- The mains plug must be freely accessible.
- Use only a grounded receptacle (properly groun
ded receptacle).
- Lay the power cord so that it does not interfere with
work and can not be damaged.
- Protect the power cord from heat, aggressive li
quids and sharp edges.
The motor switches off automatically when overloaded.
After a cooling time (different times), the engine can be
switched on again. First, the cause of the overload must
be resolved.
8.3 Connection for extraction system
When used in closed rooms, the machine must be
connected to an exhaust system. The flow velocity at the
extraction nozzle must be min. 20 m / s.
ount the extraction hose of the extraction system on
the extraction nozzle on the back of the grinding machine
(suction nozzle diameter 38 mm).
8.4 Mounting the tool
Step 1: Prepare the appropriate tools.
Step 2: Check that the machine is switched off and dis-
connected from the mains.
Fig. 5: Insert lower spindle disc
Step 3: Place the lower spindle disc on the spindle and
push it downwards.
ANGER!
Before starting any assembly work on the machine, it
must be disconnected from the mains.
Handling and working with the machine is only per-
mitted to persons who are familiar with the handling
and operation of the machine.
ANGER!
anger to life due to electric shock!
There is danger to life when in contact with live com-
ponents. Switched on electrical components can
cause uncontrolled movements and lead to serious
injuries.
ANGER!
All work on the electrical installation may only be car-
ried out by a qualified electrician.
