The specified vibration value can be used for initial
assessment of a harmful effect.
Keep the noise emissions and vibrations to a mini-
mum.
•
Only use appliances which are in perfect working
-
order.
•
Service and clean the appliance regularly.
•
Adapt your working style to suit the appliance.
• Do not overload the appliance.
•
Have the appliance serviced whenever necessary.
• Switch the appliance off when it is not in use.
• Wear protective gloves.
7. Before putting the machine into op-
eration
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 fit
-
ted before the equipment is switched on.
•
The grinding and polishing wheel must rotat freely.
• Check that the voltage on the rating plate is the same
as your supply voltage before you connect the equi
ment to the power supply.
7.1 Fitting the spark refl ector (Fig. 2-4 / Item 3)
Fit the spark refl ector (3) to the double wheel grinder
using the adjusting screw (10).
7.2 Adjusting the spark refl ector
(Fig. 5 / Item 3)
•
Adjust the spark deflector (3) using the adjusting
screw (10) so that the distance between the dry grind
-
ing 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 compen
-
sate for wear on the wheel.
7.3 Fitting the workpiece supports (Fig. 6 / Item 8)
Secure the workpiece supports (8) to the double wheel
grinder using the star screw (7).
7.4 Adjusting the workpiece supports (Fig. 7 / Item
8)
•
Adjust the workpiece supports (8) using the star
screws (7) so that the distance between the dry grind
-
ing 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).
•
Always keep proper footing and balance.
•
After you have finished grinding metal, allow the
grinding wheel(s) to come to a standstill.
•
When taking a break from your work, before carrying
out any tasks on the device itself and when you are
not using the device, always pull the mains plug out
of the mains socket.
•
Handle the device carefully and treat it with respect.
Always keep the device clean, dry and free of oil or
grease.
•
Remain alert at all times! Always watch what you are
doing and proceed with caution. Do not use the de-
vice if you cannot concentrate or you are feeling un
-
well.
•
Store grinding wheels in such a way that they are not
subject to mechanical loads or damaging environ-
mental influences.
