| Residual risks
---|---

The machine has been built according to the state of the art and the recognised technical safety requirements. However, individual residual risks can arise during operation.

Health hazard due to electrical power, with the use of improper electrical connection cables.
Furthermore, despite all precautions having been met, some non-obvious residual risks may still remain.
Residual risks can be minimised if the „safety instructions“ and the „Proper use“ are observed along with the whole of the operating instructions.
Do not load the machine unnecessarily: excessive pressure when sawing will quickly damage the saw blade, which results in reduced output of the machine in the processing and in cut precision.
When cutting plastic material, please always use clamps: the parts which should be cut must always be fixed between the clamps.
Avoid accidental starting of the machine: the operating button may not be pressed when inserting the plug in an outlet.
Use the tool that is recommended in this manual. In doing so, your mitre saw provides optimal performance.
Hands may never enter the processing zone when the machine is in operation.
Release the handle button and switch off the machine prior to any operations.

Accessories

SAW DUST EXTRACTION

The mitre saw is equipped with an extraction port to which an extraction system can be connected. Alternatively, a dust bag can also be attached.
The hose of the extraction system is fastened on the extraction port with a clamp. We recommend emptying the bag or container from time to time and cleaning the filter.
The air speed of the suction system must be at least 30 metres per second.

Maintenance

---|---

If personnel qualified for unusual maintenance tasks or repairs must be obtained during of after the warranty period, please always contact a service point recommended by us or contact the manufacturer.

Only perform repair, maintenance and cleaning work as well as the correction of malfunctions with the drive switched off as a basic rule.
All protective and safety equipment must be reassembled immediately after repair, maintenance is completed.

NORMAL SERVICE TASKS

Normal service tasks can also be performed by untrained personnel and are all described in the preceding sections and in this chapter.

The mitre saw must not be lubricated, because it always cuts dry surfaces; all moving machine parts are self-lubricating.
In the event of service work, personal protective equipment must always be work (protective goggles and gloves).
Remove saw dust and chips regularly by cleaning the cutting zone and support surfaces.
We recommend using a suction tool or brush.

ATTENTION : Do not use compressed air! Check the saw blade from time to time: If problems arise with the blade, it must be ground by a specialist or replaced, depending on the condition.

DECOMMISSIONING OF THE MACHINE
After the machine is decommissioned it can be disposed of with normal industrial waste.

Troubleshooting

Fault	Possible cause	Remedy
Motor does not work	Motor, cable or plug defective, fuses burnt	Arrange for

inspection of the machine by a spe- cialist. Never repair the motor yourself. Danger! Check fuses and replace as necessary
The motor starts up slowly and does not reach operating speed.| Voltage too low, coils damaged, capacitor burnt| Contact the utility provider to check the voltage. Arrange for inspection of the motor by a special- ist. Arrange for replacement of the capacitor by a specialist
Motor makes exces- sive noise| Coils damaged, motor defective| Arrange for inspection of the motor by a special- ist
The motor does not reach its full power.| Circuits in the network are overloaded (lamps, other motors, etc.)| Do not use any other equipment or motors on the same circuit
Motor overheats eas- ily.| Overloading of the motor, insufficient cooling of the motor| Avoid overloading the motor while cutting, remove dust from the motor in order to ensure optimal cooling of the motor
Reduced cutting power when sawing| Saw blade too small (ground too much)| Readjust end stop of the saw unit
Saw cut is rough or wavy| Saw blade dull, tooth shape not appropriate for the material thickness| Resharpen saw blade and/or use suitable saw blade
