Maggi 16430201, Original Use And Maintenance Manual

Page: 26 / 56

POSSIBLE CAUSE WHAT TO DO
A. Drill is not clamped correctly
B. Drills are worn
C. Piece to be worked is not clamped cor-
rectly - Check clamping. If it is correct call service intervention.
- Replace or call technical service
- Check hold down clamps, hold down clamps gaskets and
working pressure
20.3 HOLE IS NOT PRECISE
POSSIBLE CAUSE WHAT TO DO
A. Possible breakage in
-gears and/or keys
Transmission joint - Replace (call technical service)
20.1 DRILLS ARE NOT TURNING
21. PROBLEMS THAT MIGHT OCCUR DURING MACHINE WORKING CYCLE
21.1 DRILLS LEAVING SCORCH MARKS
This problem might occur if the piece is not positioned correctly on the table, if drills are worn or are turning in
the opposite direction.
21.2 BORED PIECES ARE NOT PARALLEL TO STOP
This problem might be due to the fact that the drills are not parallel to reference stop. Check head position to
stop and make sure drills line in head 1 and 2 is parallel.
21.3 HOLD DOWN CLAMPS CANNOT CLAMP WOOD PIECE
If hold down clamps cannot clamp pieces, check air pressure and connection pipes.
To solve these problems, we suggest that you contact MAGGI Post-sale Assistance Service or your local
dealer.
22. A. NOISE LEVEL
Assuming the machine is functioning properly and that tool balancing and sharpness are correct, noise emis-
sions can vary according to the material being worked, to drills diameter and to boring depth. Length of time
operators are expected to stay close to the machine can vary over the 8-hour working day. Other factors play a
role in determining the exposition level, such as surrounding environment and other sources of noise as well as
the presence of other machines nearby. We advise you to inform operators about risks resulting from a long
exposition to noise and, if necessary, provide them with suitable individual protection devices. The acoustic
pressure level detected with a class-1 integrating noise meter at operator’s working position is
76.1dB (A).
This
measurement has been carried out in compliance with ISO 3745 standard. During this measurement, the ma-
chine was functioning at steady state as far as pressure and speed were concerned, and was drilling a wooden
shaving panel with PVC covering. The measurement has been carried out at a 1.5-meter height in front of the
machine at the operator’s working location. The following reference measurements have been obtained by fol-
lowing the same procedure:
Acoustic pressure level in Atm. dB(A):78.3
Acoustic power level dB(A):93.3
22. B. DUST EMISSIONS
These are the results of a test carried out to determine the level of dust emissions during a non-stop working
hour, while a 20 mm-thick fir panel with PVC covering was being bored. Dust emissions amounted to 13.9 mg/
N cu.m at operator’s working location, which is at a 1.5-meter height in front of the machine.
20.2 ENGINE IS RUNNING BUT DRILLS ARE NOT TURNING
POSSIBLE CAUSE WHAT TO DO
A - The engine not running
B - The engine is burnt out - Press the engine operational button
- Release emergency pushbutton and/or check fuses
- Check air pressure (to switch pressure switch on)
- Replace the engine
20. COMMON FAILURES - CAUSES AND SOLUTIONS
Some failure causes can be eliminated by the operator himself, while others failures need qualified personnel
intervention.
CAUTION: BEFORE CARRYING OUT ANY INTERVENTION YOU MUST STRICTLY
FOLLOW THE MACHINE CUTTING-OFF PROCEDURE DESCRIBED IN CHAPTER 16.
