surface. Dust particles may enter the mechanism.
• Always switch off the machine first before removing
the plug from the wall socket.
Never use the spindle lock to stop the motor.
TROUBLESHOOTING
1. Machine fails to operate:
• Power turned off
• (Extension) cable damaged
2. The elektromotor hardly reaches maximum
speed:
• The extension cable is too thin and/or too long
• The mains voltage is lower than 230 V
3. Machine overheats:
• Air vents are blocked. Clean them with a dry cloth.
• The machine has been overloaded. Use the machine
for the purpose it is made for.
4. Excessive sparking or elektromotor runs
irregular.
• There’s dirt inside the motor or the carbon brushes
are worn. Replace the carbon brushes or bring the
machine to a specialized repair centre.
5. SERVICE & MAINTENANCE
MAINTENANCE
Make sure that the plug is removed from the mains when
carrying out maintenance work on the motor.
The Powercraft machines have been designed to
operate over a long period of time with a minimum of
maintenance. Continuous satisfactory operation
depends upon proper machine care and regular cleaning.
CLEANING
Regularly clean the machine housing with a soft cloth,
preferably after each use. Keep the ventilation slots free
from dust and dirt. If the dirt does not come off use a soft
cloth moistened with soapy water. Never use solvents
such as petrol, alcohol, ammonia water, etc. These
solvents may damage the plastic parts.
LUBRICATION
The machine requires no additional lubrication.
FAULTS
Should a fault occur, e.g. after wear of a part, please
contact the adress on the warranty card. In the back of
this manual you find an exploded view showing the parts
that can be ordered.
ENVIRONMENT
In order to prevent the machine from damage during
transport, it is delivered in a sturdy packaging. Most of
the packaging materials can be recycled. Take these
materials to the appropriate recycling locations.
Faulty and/or discarded electrical or electronic
apparatus have to be collected at the appropriate
recycling locations.

from the mains supply (use non metallic objects) and
avoid damaging internal parts.
• Though poor conditions of the electrical mains,
shortly voltage drops can appear when starting the
equipment. This can influence other equipment (eq.
blinking of a lamp). If the mains-impedance Zmax
<0.348 Ohm, such disturbances are not expected.
(In case of need, you may contact your local supply
authority for further information.
3. ASSEMBLY
Prior to mounting an accessory always unplug the
tool.
MOUNTING A GRINDING DISC.
Fig 2
Use grinding discs of the correct dimension. Use fibre
reinforced grinding discs only. The grinding disc must
not touch the edge of the guard.
• Press the spindle lock (3) and turn the spindle (10)
until it engages in the lock. Keep the spindle lock
pressed during this procedure.
• Remove the flange nut (11) from the spindle using the
spanner (12).
• Position the grinding disc (4) on the flange (9).
• Place the flange nut on the spindle an tighten it using
the spanner.
• Release the spindle lock and check that the spindle is
unlocked by rotating it.
MOUNTING THE PROTECTIVE GUARD
Fig. 2+3
Tool-les protective guard
The protective guard is pre-adjusted for the diameter of
the spindle shaft. If necessary, the tension of the clamping
lever can be adjusted by turning the adjustment-bolt
(13). Pay attention to the correct fitting of the guard (7)
on the spindle shaft (10).
• Open the clamping lever (14)
• Place the protective guard across the spindle shaft on
the machine head in the required position
• Close the clamping lever (14) to clamp the
protective guard (7).
Warning: the closed side of the protective guard has to
point towards the user.
ROTATING THE HANDGRIP
Fig. 4
The handgrip can be rotaded 90oregard to the machine
housing. This can result in a better control of the On/Off
switch during special working positions; for example for
grinding or left-hand users.
• Pull the knob (8) backwards with thumb and
forefinger.
• Rotate the handgrip in the new position (until the
blocking).
MOUNTING THE SIDE HANDLE
Fig 1
The side handle can be used for both left-hand and right-
hand control.
• Fasten the side handle (Fig. 5) for left-hand operation
on the right-hand side of the machine.
• Fasten the side handle for right-hand operation on
the left-hand side of the machine.
• Fasten the side handle for upright working at the top
of the machine.
Make sure that the side handle is fastened
properly and cannot loosen unexpectedly.
MOUNTING GRINDING DISCS AND
ROUGHING DISCS
Fig. 3 and 4 show how to mount the flange (11) when
using thick (4 – 8 mm) and thin (2,5 – 4 mm) discs.
4. USE
SPECIAL ATTENTION WHEN STARTING
THE MACHINE
• Clamp the workpiece and make sure that the
workpiece cannot slide from under the machine
during the cutting activities.
• When working with the machine, always hold it
firmly with both hands and provide for a secure
stance.
• Always direct the cable to the rear away from the
machine.
• Insert the mains plug only when the machine is
switched off.
• Apply the machine to the workpiece only when
switched on
Never use the machine for grinding magnesium
workpieces.
SWITCHING ON AND OFF
• This machine is equipped with a safety switch.
• Start the machine by pressing the “lock off” button
(to disengrage the switch) and switch on the
machine.
Before start working, the machine must be run
according to the max. speed.
OPERATION
• Hold the machine firmly and move it against the
workpiece. Move the grinding disc evenly across the
workpiece.
• Move the machine during roughing under an angle of
30º - 40º across the workpiece (fig. 7).
Never use grinding discs for roughing!
• The machine must always work opposite to the
direction of rotation. Therefore, never move the
machine in the other direction! Otherwise, the
danger exists of it being pushed uncontrolled out of
the cut (fig. 8).
• Inspect the grinding disc regularly. Worn discs have a
negative effect on efficiency of the machine. Replace
the grinding disc on time.
• Do not put the machine down when the motor is still
running. Do not place the machine on a dusty
