Maintaining the Safety Fence
The safety fence should be cleaned thoroughly at regular intervals. The contact surfaces between the fence and
the fence plates and between the fence and the table top are particularly important. Dust can accumulate at
these points, leading to inaccuracies in the setting of the safety fence.
19.4
Checking the Electronic Motor Brake
•
The machine has an electronic brake for electrodynamic braking of the motor.
•
If the machine is switched off with the red push button (3) shown in
Figure 11, the braking time until the
spindle stops completely must not exceed 10 seconds.
•
This braking time must be checked once a month. If it is more than 10 seconds, the motor brake must be
checked by a qualified electrician.
•
Important:
The motor brake is designed for a maximum of 10 braking operations per hour.
19.5
Checking the Emergency Stop Button
•
Check the function of the emergency stop button weekly. To do this, press the emergency stop button while
the machine is running
→
The machine switches off the motor immediately and the spindle stops after the
braking time has elapsed.
•
To restart the machine, the emergency stop button must be unlocked again (turn to the right or pull out).
19.6
Checking the Safety Devices
The following safety devices must be checked at regular intervals:
19.6.1
Checking the Safety Fence

•
the correct fixing of the safety fence on the table top,
•
the correct seating of the fence plates on the safety fence,
•
the protective bonnet of the fence for cracks and damage, and

and the fence plates for damage or bending.
Tighten loose clamp connections and fixings well with the appropriate levers, handles or
screws and replace defective, damaged or bent parts immediately!
19.6.2
Checking the internal Safety Switches
•
Open the service door
→
When switching on, the machine must not start if the door is open.
•
Activate the spindle lock (see chapter
12) and close the service door properly
→
When switching on, the machine must not start with the spindle lock activated.
19.6.3
Checking the Protective and Pressure Device
Check weekly
•
the proper function of the pressure shoes and pressure elements,
•
all components of the protective and pressure device for damage and defects,
•
all handles, levers and screw connections required for adjustment for damage and defects.
Tighten loose clamp connections and fixings well with the appropriate levers, handles or
screws and replace defective, damaged or cracked parts immediately!

Check regularly that all safety labels on the machine are present and in good legible condition.
•
The safety labels must be completely present and always clearly legible.
This applies especially to the safety instructions.
