Maintenance

Always switch off the motor and disconnect the plug from
the power supply prior to any maintenance and cleaning
work.
The following maintenance points should be checked on the
scheppach Precisa 6.0 circular saw blench.
• Check the belt tension after approximately one operating
hour; retension if necessary.
For this purpose Open the upper side wall. By uniform
adjustment of the fastening nuts on the motor, adjust the
necessary belt tension.After this first initial adjustment,
check the belt tension at regular intervals.
• Occasionally, oil the roller chain and moving parts (height
and angle adjust- ment).
• Ensure that the bench surface is always free of resin.
• If the circular saw bench is not connected to an extractor,
then it will be necessary to remove the saw dust and wood
chips that accumulate in the protective blade box. This is
important to ensure trouble- free ejection of the saw dust.
Remove the left blade-slot insert. If suction System is not
connected when working, the height and angle adjustment
range may be restricted due to chip accumulation.
All protection and safety devices must be replaced after
completing repair and maintenance procedures.
• The saw protection box must be clea- red occasionally of
wood shavings and saw dust so that shavings do not jam
when ejected.
• he height and angular adjustment area may be reduced by
shaving deposits. Remove the left bench inlay and clean the
adjustment area.

Electrical connection

The installed electric motor is com- pletely wired ready
for operation.
Yhe customer's connection to the power supply system, and any
extension cables that may be used, must conform with local
regulations.
Motor braking unit
The scheppach machine is fitted with an automatic motor
braking unit which becomes effective as soon as the driving
motor is switched off.
The saw blade must stop maximal 10 seconds after switching
it off. Poof daily!
If it takes longer, do not use the machine anymore.

lmportant information
The 230 V / 50 Hz and 400 V / 50 Hz electric motor is designed
for the S6 / 40% operating mode.
The motor automatically switches off if it is overloaded. The
motor can be switched on again after a cooling- down period
(varies timewise).
Faulty electrical connecting leads
lnsulation damage often occurs at elec- trical connecting
leads.
Causes include:
• Pressure marks caused when connec- ting leads are run
through windows or the cracks of doors.
• Folds caused by the improper attach- ment of running of
the connecting leads.
• Cuts resulting from the crossing of the connecting lead.
• lnsulation damages caused by the ripping out of the
connecting lead from the wall socket.
• Cracks due to the ageing of the insulation.
Faulty electrical connecting leads such as these may not be used
and are highly dangerous due to the insu- lation damage.
Check electrical connecting leads regu- larly for damage.
Ensure that the connecting lead is not attached to the mains
supply when you are checking it.
Electrical connecting leads must corre- spond to the relevant
VDE and DIN regu- lations. Only use connecting leads with
the code H 07 RN.
The type designation must be printed on the connecting lead
by regulation.
Single-phase motor
• The supply voltage must be 230 volt - 50 Hz.
• Extension leads up to 25 m in length must have a
cross-section of 1.5 mm2. Extension leads whose length is
over 25 m must have a cross-section of at least 2.5 mm2
• The mains connection is fused with a 16 A slow-blow fuse.
Three-phase motor
The 400 V / 50 Hz electric motor is designed for the S6 / 40%
operating mode.
• The supply voltage must be 400 volt - 50 Hz.
• The mains connection and the exten- sion lead must have
5 wires = 3 P + N + PE.
• The extension cables must have a minimum cross-section
of 1.5 mm2
• The mains connection is maximally fused with a 16 A fuse.
• The phase-sequence must be checked if the mains
connection or the location is changed. The polarity must
be changed, if necessay (wall socket)
Connections or repairs on the electrical equipment may only
be carried out by an electrician.
Please give the following information if you have any enquiries.
• Motor manufacturer
• Kind of current
• Machine type label data
If your are sending back the motor, always send the complete
drive unit with the switch.
