The electrical motor installed is connected and ready for operation. The connection complies with the applicable VDE and DIN provisions. The customer‘s mains power connection as well as the extension lead used must also comply with these regulations and the local regulations. Check the electrical connection cables for damage regularly. Ensure that the connection cables are dis- connected from electrical power when checking for damage. Electrical connection cables must comply with the applicable VDE and DIN provisions. Only use con- nection cables with the marking „H 07 RN“. The printing of the type designation on the cable is mandatory. Damaged electrical connection cables The insulation on electrical connection cables is often damaged. Causes are:

• Pressure points, where connection cables are passed through windows or doors.

• Kinks where the connection cables have been im- properly fastened or routed.

• Places where the connection cables have been cut due to being driven over.

• Insulation damage due to being ripped out of the wall outlet.

• Cracks due to the insulation ageing. Such damaged electrical connection cables must not be used and are life-threatening due to insulation damage! 3-phase motor 400 V / 50 Hz Mains voltage 400 V / 50 Hz Mains power connection and extension leads must be 5-core = 3 P + N + SL. - (3/N/PE). Extension cables must have a minimum cross section of 1.5 mm² (≤ 25 m). Extension cables must have a minimum cross sec- tion of 2.5 mm² (> 25 m). The mains power connection is protected with a 16A slow-blow fuse. The RCD circuit 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 turn- ing direction must be checked. It may be necessary to change the polarity. Turn the pole changing device in the device connector. Motor braking device The brake brakes the drive motor of the sawing shaft within 10 s. The electric braking is interrupted after max. 14 s. If the braking process takes longer than 10 s, the machine must no longer be operated because the brake is defective. It is essential to disconnect the machine from the power supply. Only a qualied electrician may be assigned with troubleshooting. Operating mode / duty cycle The electric motor is designed for operating mode S6 - 20 %. S6 = Continuous operation with intermittent load 20% = Based on 10 min: 2 min. load; 8 min. idle mode.

Topping up with fuel m WARNING Petrol is highly ammable:

• Only store petrol in the designated containers.

• Only refuel the unit outdoors and do not smoke whenlling.

• Petrol must be lled before starting the engine. While the engine runs or if the engine is hot, the fuel cap must not be opened and petrol must not belled.

• If petrol overows, no attempts should be made to start the engine. Instead, the machine must be removed from the area contaminated with petrol. Do not try to start the engine until the fuel vapours have evaporated.

• For safety reasons, fuel tank and other tank caps must be replaced if damaged.

• Never store petrol near a source of sparks. Always use a tested canister. Keep petrol away from chil- dren.

Starting the engine Only valid for petrol version Follow the procedure below for cold starting:

1. Turn the fuel valve (B) to the right to the

2. Turn the choke lever (A) on the engine

fully to the left, to the “ON” position.

3. Set the throttle lever (C) to the half-open

4. Turn the ignition switch (E) to ON.

5. Pull the recoil starter handle (D) slow-

lyseveraltimessothatthepetrolows into the carburettor. Then hold the recoil starter handle (D) and pull the cord out a little until you feel resistance. Then pull the cord out in one quick movement and let the cord wind up again slowly. Do not let the cord recoil. If necessary, pull the recoil starter handle (D) several times until the engine starts. 6. Let the engine warm up for a few seconds. Then gradually move the choke lever (A) to the right to the “OPEN” position. Restarting an engine that is already warm from previous operation does not normally require the use of the choke.

1. Turn the fuel valve (B) to the right to the open position.

2. Set the throttle lever (C) to the half-open position.

3. Turn the ignition switch (E) to ON.

4. Then hold the recoil starter handle (D) and pull the cord out a little until you feel resistance. Then pull out the recoil starter handle (D) in one quick movement and let the cord wind up again slowly. Do not allow the recoil starter handle (D) to recoil. After the engine has started, move the throttle lever (C) to the full throttle position so that the saw blade can reach its maximum speed. Work complete

• Slowly move the throttle (C) to the stop position.

• Bring the swivel frame to the transport position and secure it with the swivel frame lock. The HS720 und HS720B provides maximum safety thanks to its enclosed sawing area.

• Open the protective cover (1).

• Insert the material to be cut.

• Close the protective cover (1).

• Swivel the rocking frame (2) with hand grip (A) or (B) to the saw blade and saw through the material to be cut.

• Swivel the rocking frame (2) back and open the protective cover.

• Add more material to be cut and close the protective cover again.

15. Sawing operation

1. After the machine has been switched on, wait until

the saw blade has reached full speed.

2. Place the wood in the swivel frame.

3. Hold the handle of the swivel frame with both

hands and guide it evenly towards the saw blade.

4. Only apply enough pressure on the swivel frame

when sawing so that the speed of the saw blade does not drop.

5. Remove the sawn wood from the swivel frame af-

ter it has returned to its original position and the saw blade is covered. Now place the next piece of wood on. m Attention!

• Do not leave the machine unattended during op- eration.

16. Maintenance and service

m Only carry out maintenance, modication, adjustment and cleaning work when the engine is switched o󰀨 and the mains plug connector is disconnected or the fuel valve is closed.

• Keep the instructions with the machine.

• Keep the machine clean.

• Wear safety goggles when cleaning.

• Attention!Dangerofreduetochipsintheevent thecleaningcarriedoutisinsu󰀩cient. Before starting the maintenance or checks, clean the work area and have suitable tools at hand and in good condition. The time intervals relate to normal operating condi- tions. If the machine is subjected to heavier loads, these times must be reduced accordingly. Clean the machine cladding, panels and control levers with a soft, dry cloth or a cloth that has been slightly moistened with neutral cleaning agent. Do not use any solvents such as alcohol or petrol as these may damage the surfaces. Keep oils and lubricants out of reach of unauthorised persons. Read through the instructions on the con- tainers carefully and follow them closely. Avoid direct contact with the skin and wash o󰀨 thoroughly after use. m Check all safety devices after all maintenance or cleaning work. 1www.scheppach.com

Servicing Switchtheengineo󰀨andletitcooldown.Pulloutthe mains plug or close the fuel valve. Check the general condition of the machine. Check for loose screws, misalignment or jamming of moving parts, part breakages and other conditions that could impair safe operation. Remove all foreign objects and other materials that have collected on the saw blade and on the unit. Clean the machine after every use. Then use a high-quality, low-viscosity machine oil to lubricate all moving parts. m Never use a high-pressure cleaner to clean your machine. Water can penetrate sealed areas of the machine and the transmission housing and cause damage to spindles, gear wheels, bearings or the engine. The use of high-pressure cleaners shortens the service life and reduces the ease of maintenance. Experienced craftsmen can carry out small repairs on the machine themselves.

• Check the saw blade at regular intervals. Only use saw blades that are free of cracks and not de- formed. Only use tools that comply with the Euro- pean standard DIN EN 847-1.

• Replace worn swivel frame bearings immediately.

• Check all safety devices after all maintenance or cleaning work.

• Check that no tools or miscellaneous parts are on or in the machine before putting it back into operation.

• Remove any sawdust accumulations that may arise at the discharge. Service information With this product, it is necessary to note that the fol- lowing parts are subject to natural or usage-related wear, or that the following parts are required as con- sumables.
