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 pro-
perly 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.
5.1 Fitting the spark refl ector
(Fig. 2-4 / Item 3)
Fit the spark refl ector (3) to the double wheel grin-
der using the adjusting screw (10).
5.2 Adjusting the spark refl ector
(Fig. 5 / Item 3)
•
Adjust the spark deflector (3) using the adjus-
ting screw (10) so that the distance between
the dry grinding wheel (5) and the spark de-
flector (3) is as small as possible and certain-
ly does not exceed 2 mm.
•
Adjust the spark deflector (3) periodically to
compensate for wear on the wheel.
5.3 Fitting the workpiece supports

Secure the workpiece supports (8) to the double
wheel grinder using the star screw (7).
5.4 Adjusting the workpiece supports

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 grin-
ding 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 oppo-
site 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).
5.6 Installing the fl exible 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 fl exible shaft (12), the
safety glass (2) must be placed right up against
the workpiece support (8) in order to prevent un-
controlled touching of the wheels.
5.7 Inserting the various tools into the fl exib-
le shaft (Fig. 11)
1. Press the locking pin (13) which is provided
into the hole in the fl exible shaft (12) and turn
the collet chuck (b) using the wrench (14 )
which is also provided until the locking pin
(13) locks into place.
2. Loosen the collet chuck nut (b) using the
wrench (14) which is provided.
