Proper use

The double-wheel grinder is a combination tool for the grinding and polishing of metals, plastics and other materials using the appropriate grinding wheels.

The flexible shaft is designed for the grinding, de burring, polishing, engraving, cutting, milling and cleaning of wood, metal and plastic in model making, in workshops and in the home. Use the tool and its accessories only for the applications described.

The machine is allowed to be used only for its intended purpose! Even when the equipment is used as prescribed it is still impossible to eliminate certain residual risk factors. The following hazards may arise in connection with the machine‘s construction and layout:

• Contact with the grinding wheel where it is not covered.
• Catapulting of parts from out of damaged grinding wheels.
• Catapulting of workpieces and parts of workpieces.
• Damage to hearing if essential ear-muffs are not used.

The equipment is allowed to be used only for its prescribed purpose. Any other use is deemed to be a case of misuse. The user/operator and not the manufacturer will be liable for any damage or injuries of any kind resulting from such misuse.

Please note that our equipment has not been designed for use in commercial, trade or industrial applications. Our warranty will be voided if the equipment is used in commercial, trade or industrial businesses or for equivalent purposes.

1. Lung damage if no suitable protective dust mask is used.
2. Damage to hearing if no suitable ear protection is used.
3. Health damage caused by hand-arm vibrations if the equipment is used over a prolonged period or is not properly guided and maintained.

Before starting the equipment

Before you connect the equipment to the mains supply make sure that the data on the rating plate are identical to the mains data. Always pull the power plug before making adjustments to the equipment.

Pull the power plug before doing any maintenance or assembly work on the equipment.

• The machine must be set up so that it stands firmly, i.e. it must be securely screwed to a work bench or similar.
• All covers and safety devices have to be properly fitted before the equipment is switched on.
• The grinding and polishing wheel must rotate freely.
• Check that the voltage on the rating plate is the same as your supply voltage before you connect the equipment to the power supply.

Fitting the spark reflector

**(Fig. 2-4 / Item 3)

**

Fit the spark reflector (3) to the double wheel grinder using the adjusting screw (10).

Adjusting the spark reflector

(Fig. 5 / Item 3)

• Adjust the spark deflector (3) using the adjusting screw (10) so that the distance between the dry grinding wheel (5) and the spark deflector (3) is as small as possible and certainly does not exceed 2 mm.
• Adjust the spark deflector (3) periodically to compensate for wear on the wheel.

Fitting the work piece supports

(Fig. 6 / Item 8)

Secure the work piece supports (8) to the double wheel grinder using the star screw (7).

Adjusting the work piece supports

(Fig. 7 / Item 8)

• Adjust the workpiece supports (8) using the star screws (7) so that the distance between the dry grinding wheel (5) and the workpiece support (8) is as small as possible and certainly does not exceed 2 mm.
• Adjust the workpiece supports (8) periodically to compensate for wear on the dry grinding wheel (5).

Changing the wheels

**(Fig. 8-9)

**

Remove the 3 screws (A) holding the side section of the safety hood (B) and remove the safety hood. Slacken the nut (D) (Important: The grinding wheel on the left is fastened with a left handed thread and the grinding wheel on the right with a right-handed thread) by holding the nut of the grinding wheel mount on the opposite side. Then remove the fl ange (C) and replace the grinding wheel (5). To assemble, proceed in the reverse order. The grinding wheel is mounted with the help of a rag. Mount the fl ange (C) and the nut (D) on the shaft and hold steady with the help of a rag when you tighten the nut (D).

Installing the flexible shaft

**(Fig. 10)

**

• Insert the internal axle (a) of the flexible shaft (12) into the guide shaft of the equipment.
• Secure the fastening nut of the flexible shaft to the equipment thread by hand (left-hand thread).

Important!
When you work with the flexible shaft (12), the safety glass (2) must be placed right up against the workpiece support (8) in order to prevent uncontrolled touching of the wheels.

Inserting the various tools into the flexible shaft

**(Fig. 11)

**

1. Press the supplied locking pin (13) into the hole in the fl exible shaft (12) and turn the shaft until the pin latches in place.
2. Now undo the collet chuck nut.
3. Insert the required tool into the sleeve as far as the stop and screw the collet chuck nut tight.

Operation

On/Off switch (1)

To switch on the equipment set the On/Off switch (1) to position I.
Move the On/Off switch (1) to position 0 to switch off the equipment.

Important!
When you are not working with the flexible shaft (12), it is not allowed to be mounted on the equipment because it could then fly around out of control.

After switching on, wait for the equipment to reach its maximum speed of rotation. Only then should you begin with the grinding.

Speed selector  **(Fig. 1)

**

The required speed can be set with the speed control (11)

Speed of the flexible shaft

The correct speed depends on the tool used and the type of material being processed.

Information on speed settings

• Small cutters/grinding pins: High speed
• Large cutters/grinding pins: Low speed

Work practice

• Exert only moderate pressure on the workpiece so that it can be machined at constant speed.
• Instead of accelerating your work, high pressure will cause the drive unit to slow down and even stop, thus overloading the motor.
• For your own safety, it is essential to secure small workpieces with a screw clamp or vise.
• Precision work/engraving: hold the drive unit like a pen.
• Rough work: hold the drive unit like the handle of a hammer.

Grinding

• Place the workpiece onto the workpiece support (8) and slowly guide the workpiece towards the grinding wheel (5) at the desired angle to the point where workpiece and grinding wheel make contact.
• Move the workpiece slightly back and forth to produce an optimal grinding result. This way the grinding wheel (5) will be evenly worn. Allow the workpiece to cool down occasionally.

Important!
If the grinding wheel becomes jammed during operation, remove the workpiece and wait until the tool reaches its top speed again.

Polishing

• Apply a thin coating of polishing paste to the grinding surface of the polishing wheel (6)
  (Fig. 18/ Item 3).

• Press on the work piece in the polishing direction and move back and forth from left to right in a pendulum action.

• Always carry out polishing work in the direction of rotation of the polishing wheel (6).

Important!
Polishing in  the opposite direction to the direction of rotation of the polishing wheels can cause damage to the polishing wheels, which in turn can result in injuries.

Replacing the power cable

If the power cable for this equipment is damaged, it must be replaced by the manufacturer or its after-sales service or similarly trained personnel to avoid danger.

Cleaning, maintenance and ordering of spare parts

Always pull out the mains power plug before starting any cleaning work.

Cleaning

• Keep all safety devices, air vents and the motor housing free of dirt and dust as far as possible. Wipe the equipment with a clean cloth or blow it with compressed air at low pressure.
• We recommend that you clean the device immediately each time you have finished using it.
• Clean the equipment regularly with a moist cloth and some soft soap. Do not use cleaning agents or solvents; these could attack the plastic parts of the equipment. Ensure that no water can seep into the device. The ingress of water into an electric tool increases the risk of an electric shock.

Maintenance

There are no parts inside the equipment which require additional maintenance.

Ordering replacement parts:
