When the motor gets overcharged, it automatically switches off. After a short cool-down period (time varies) the motor can be switched on again.

Defective electrical power supply cords

Electrical power supply cords often suffer insolation damages. Causes are:

• Pressure spots, when power supply cords are being led through windows or doors.
• Buckling spots by incorrect attachment or guidance of

the power supply cords.

• Cuttings by driving over a power supply cord.
  Insulation damages through pulling out of the socket.
• Cracks in worn-out insulation.

Such defective electrical power supply cords should not be used and are extremely dangerous because of the insulation damage.

Check electrical power supply cords for damages on a regular basis. Please observe that upon checking the power supply cord is not plugged in. Electrical power supply cords have to comply with the relevant VDE - and DIN regulations. Only use power cables with the qualification H 07 RN. An imprint of the type denomination is rule.

The supply voltage should be 230Volt / 50Hz
- Extension cables must be up to 25m long, have a cross cut of 1.5 square millimeter, be over 25m long, and have a minimum 2.5 square millimeter.
The powersupply should be 16 A.

Rotary current motor, Page U5

The power supply should be 400Volt / 50Hz
The power supply and the extension cables must be 5-fold leads = 3P + N + SL
- Extension cables must have a minimum cable cross section of 1.5 square millimeter.
The power supply should be maximum 16 A.
- In case of connection to the power supply or moving site the rotary direction should be checked, otherwise the polarity has to be changed (wall mounted connector). Therefore screw the phase switcher into the plug surrounding with a screw driver. (See Fig. 10)

Connections and repairs of the electrical equipment should only be carried out by an electrical specialist.

In case you have further questions, please specify the following:

• Motor manufacturer
  -Current type of the motor
  Information of the machine type label

Implementation

Please read the safety information before implementation. The implementation of the machine is only admissible when protection and safety facilities have been installed completely.

Put the machine on a stable, even floor. If necessary attach through the bottom through the holes to the frame valves. (screws/nails)

After connection to the power supply your scheppach construction circular saw is ready to operate.

Longitudinal cuts, Fig. 11

For parallel cuts use the longitudinal end stop. To process smaller workpieces (less than 120~mm ) use the stick rail.

Use end stop rail with lower end stop height. In case of disuse take down the longitudinal end stop to the right table side.

For cutting jobs over 120mm use the end stop ruler with the high end stop side (1) and for cutting jobs under 120mm use the lower end stop side (2).

Cross cuttings, Fig. 12

For cross - and angle cuttings use the crosscut gauge.

The performance of the crosscut gauge also allows the making of wedges. The adjust scale reaches from 0^ to 90^ . Introduce the slewing unit right-angled with the sixfold screw to the saw blade.

In case of disuse deviate the crosscut gauge sideways.

A sliding table is optional.

Exchange of saw blade, Fig. 13

Be careful: pull out power plug!

• Untighten both upper screws (M8) at the lower saw blad cover.
• Deviate saw blade cover.
• Loosen clamping nut (M20 links) and hold back with retaining arbor.
• Wear gloves to protect your hands.
  Take out saw blade, introduce new one.
• Only put in well sharpened, crack-free and not disformed saw blades.
• Tighten clamping nut and hold back with retaining arbor (left-hand thread).
• Lift up the lower saw blade cover and tighten both screws (M8) again.
  After every saw blade exchange the slit wedge has to be re-adjusted. See slit wedge adjustment Fig. 08.

Maintenance

With all maintenance and cleaning works switch off the motor and pull out the power plug.

All protection and safety facilities should be fitted again after completed repair and maintenance works.

• The circular saw is to the greatest possible extent maintenance-free, including the electrical motor. Excluded are the saw blades, the table insert and the brake linings, which are subject to wear (approx.15,000 shifts) of the electrical motor. The saw blade has to stop within 10 sec. If necessary exchange the petered-out table insert.
• Brake pads should only be exchanged by specialized staff.
• Keep the table surface always resin-free.
• Keep the saw blade protection box free from wood particles and sawdust. When the power supply is pulled out, open the protection box lid, remove possible sawdust remains.
