Sound pressure level on working site in dB
Idle LqAeq / Processing LqAeq	86 / 91	86 / 91	86 / 91

The specified values are emission values and therefore should not at the same time be reliable working site values. Although there is a correlation between emission and immersion levels, it cannot unfailingly be derived if extra precautions need to be taken or not. Factors, which influence the actual available immersion value on working site, include the peculiarities of working area, other sources of noise, e.g. the number of machines and other adjoining processes. The allowed working values could vary from country to country. However, the information should qualify the user, to be able to make an estimation of the dangers and risks.

- Cardan shaft operation must be switched off when transporting the circular saw.

⚠️ Transport on public highways

Attention! When driving on public roads, it is necessary to observe the German road traffic act (StVZO) paragraph 53, 53b and 54 regarding attachments. If an attachment protrudes more than 1m to the rear beyond the tail lights of a tractor vehicle, the end must be made readily recognisable with warning signs. If visibility conditions require it, additional tail lights and reflectors must also be fitted.

If an attachment protrudes more than 40cm beyond the limiting lights or tail lights, the front and rear must be made readily recognisable with warning signs. If visibility conditions require it, additional limiting lights, tail lights and reflectors are also necessary.

Attachments must be made safe with lighting equipment if the tractor unit is concealed by the attachment. It is necessary to ensure that front ballast is installed when transporting a machine with an agricultural tractor, if this is required according to the load table for the tractor. The transport speed must not exceed 6km/h.

11. Electrical Connection

The electrical motor installed is connected and ready for operation. The connection complies with the applicable VDE and DIN provisions. The customer's mains connection as well as the extension cable used must also comply with these regulations.

Check electrical connection cables regularly for damage. Ensure that the connecting cable is not attached to the mains when you are checking it.

Electrical connecting cables must correspond to the relevant VDE and DIN regulations. Only use connecting cables with the code H 07 RN.

The type designation must be printed on the connecting cable by regulation.

Faulty electrical connecting cables

Insulation damage often occurs at electrical connecting cables.

Causes include:

• Pinch points when connecting cables are run through window or door gaps.
• Kinks resulting from incorrect attachment or laying of the connection cable.
• Cuts resulting from running over the connecting cable.
• Insulation damage resulting from forcefully pulling out of the wall socket.
• Cracks through aging of insulation.

Such defective electrical connection cables must not be used as the insulation damage makes them extremely hazardous.

Three-phase motor 400 V/50 Hz

Mains voltage 400 Volt / 50 Hz.

Mains voltage and extension cables must be 5-lead = 3 P + N + SL. - (3/N/PE).

Extension cables must have a minimum cross-section of 1.5 mm^2 ( ≤ 25m ).

Extension cables must have a minimum cross-section of 2.5 mm^2 (> 25m) .

The mains connection is protected with a 16 A slow-blow fuse. The RCD breaker must have a 30 mA trip rating.

When connecting to the mains or in the event of the machine being moved to another location, the turning direction must be checked. It may be necessary to change the polarity.

Turn pole inverter in the machine socket.

Motor-brake appliance

The brake slows down the motor of the saw shaft within 10 seconds.

The electrical braking is interrupted after maximum 14 seconds.

In case the braking takes more than 10 seconds the machine should not be used again, as the brake is defective. The machine implicitly needs to be disconnected from the power supply. Only an electronic specialist should be instructed to repair this malfunction.

Operating mode / Switch-on duration

The electrical motor is dimensioned for operating mode S6 - 40 %.

S6 = pass operation with load exposure

40% = related to 10 min. 4min. load; 6min. pass operation

If the motor is overloaded, it automatically switches off because a thermostat protects the motor against overloading. After a cool-down period (time varies) the motor can be switched on again.

Check electrical connection

- Switch on the machine with the power switch, the motor runs up.

Attention!

Check the direction of rotation!

- Three-phase AC motors must be checked for their direction of rotation in the event of a new connection or change of location. If necessary, the direction of rotation must be changed with the phase inverter (Fig. A)

- Upon switching off the saw shaft is slowed down within 10 seconds.

16. Maintenance and service

⚠ Perform maintenance, modification, adjustment and cleaning work only with the engine switched off and the mains plug or spark plug connector is unplugged.

• Keep the manual at the machine.
• Keep machine clean.
• Wear protective goggles when cleaning.

Before undertaking any maintenance or checking work, the working area must be cleaned. Keep the necessary tools within the reach of your hand.

The intervals mentioned herein are based on normal conditions of use. An excessive use of the machine shortens the intervals accordingly.

Clean the panels, screens and control levers with a soft cloth. The cloth should be dry or slightly humid with a neutral cleaning agent. Do not use any solvents like alcohol or benzene as they could damage the surfaces.

Keep oils and lubricants out of reach of unauthorised persons. Read through the instructions on the containers carefully and follow them closely. Avoid direct contact with the skin and wash off thoroughly after use.

Check the V-belt tension after the first hour of operation and every time before starting up. To do so, undo the T-screw on the motor bracket. Press the bracket down and tighten the T-screw again.

All ball bearings are lifetime lubricated. The circular saw blade is a wearing part and must be checked every time before starting up. Only a well-sharpened, correctly set saw blade delivers good cutting results. Occasional greasing of the saw blade is recommended.

If signs of wear appear in the swivel saw slit, the swivel parts must be replaced.

Maintenance

Turn the engine off and let the engine cool down. Pull out the mains plug or remove the tractor ignition key.

Check the general condition of the machine. Be careful with loose screws, misaligned or moving parts, breakage of parts, and any other condition that could interfere with safe operation.

Remove any foreign objects and other materials that have accumulated on the saw blade and the unit. Clean the machine after each use. Then use a high-quality and thin fluid machine oil to lubricate all moving parts.

△ Never use a “pressure washer” to clean your unit. Water can penetrate tight areas of the machine and its transmission case and cause damage to spindles, gears, bearings, or the engine. The use of pressure washers will result in shortened life and reduce serviceability.

Experienced craftsmen can perform minor repairs on the machine itself.

• Check the saw blade regularly. Use only well-sharpened, crack-free and not distorted saws. Use only tools that comply with the European standard EN 847-1.
  • Exchange immediately rocker that run out.

• Check all safety installations after each maintenance and cleaning activities.

• Ensure that there are no tools or other materials on or in the machine before putting it into operation.
• Remove possible sawdust blockages at the discharge.
