Beta 1933L Notice D'utilisation Et Instructions page 12

USE
Start / Stop
To start the grinder, push the safety lever forward, while pressing the start lever (picture 2-f,g). Keep the start lever pressed during the
job to be performed. Releasing the lever will cause the grinder to stop within 5s.
The grinder is fitted with a rear air outlet (picture 4-m).
When the grinding wheel stops, place the grinder in a firm and safe position. The grinding wheel does not stop immediately.
Grinding wheel installation/replacement
Install the grinding wheel on the die grinder (picture 1) as follows:
– Loosen the spindle nut of the rotating grinding wheel spindle by means of the open end wrenches;
– Fit the grinding wheel into the chuck, and lock the nut by means of the open end wrenches. Replace the interior chuck according to
the diameter of the spindle of the grinding wheel to fit in (Ø 3 mm or Ø 6 mm);
– Make sure that the grinding wheel has been fixed correctly;
– The grinder can rotate in one direction only
Replace the die grinder wheel as follows:
– Loosen the spindle nut of the rotating grinding wheel spindle by means of the open end wrenches;
– The grinding wheel has thus been released and can be removed;
– Fit in the new grinding wheel and follow the above instructions.
Wheel speed regulation
Regulate the speed of the grinder wheel as follows:
– Turn the knob in the middle of the handle (picture 4-l) to regulate speed;
– + maximum speed; – minimum speed (speed set to zero).
Always disconnect the air supply before making adjustments or fitting in the grinding wheel. This precaution will prevent the pneumatic
tool from being accidentally started.
Lubrication/Greasing
The pneumatic tool must be connected to a filter-lubricator unit (we recommend Beta item 1919F1/4) provided with an air-oil microfog
mixer, set at two drops per minute. This will result in a high-performing tool and wear-resistant mechanical parts.
If lubrication is not provided to the line, oil ISO 32 must be periodically poured into the pneumatic tool, through the air supply hole
(picture 3-h).
MAINTENANCE
Maintenance and repair jobs must be carried out by trained personnel only. For such jobs, you can contact Beta Utensili S.P.A.'s repair
centre through your Beta dealer.
DISPOSAL
The pneumatic tool, accessories and packaging should be sent to a waste disposal centre, in accordance with the laws in force in your
country.
