INSTALLATION
A: Attach the machine base plate to the work table
by means of three M8 screws or a clamp.
B: Fit the radial arm into the base axle, tighten the
2 Allen M5 and cover them with the two plastic
caps.
C: Fill up the reservoir (6b, page 35) with lubricating
pneumatique motors oil, SAE-10.
D: The air connection is carried out by means of a
notched connection located on the air FRL unit.
IMPORTANT: Table showing the ratio between
the length and inside diameter of the feeding
pipe:
SETTING IN OPERATION
Once the machine has been connected to the main,
the following points are to be checked:
1. Supply pressure: 6-8 bars for full power.
2. The pressure gauge reading can drop from 0.5 to
maximum 1.5 bars when the motor is started (if a
drop greater than 2 bars is noticed, this means that
the supply flow rate is not sufficient).
3. Make sure, by checking the sight glass (7b, page
35), that when the machine is in operation, two
to three drops per minute are fed. The regulation
is carried out by means of the control knob (7b,
page 35).
4. Arm balance: Regulate the tightness of the internal
damper if the arm descends too far, or has too
much ascending strength.
Position •: minimum tightness
Position ••: middle tightness
Position •••: maximum tightness
OPERATION
• Insert the tapholder in the motor quick change. (4a, page 35).
• Clockwise rotation: push lever (2a, page 35).
• Counterclockwise rotation: push simultaneously lever (2a, page 35) and button
(3a, page 35).
• Tapping of high pieces:
Hold the base casing, pull it up and turn it 90º to fix it. The machine will be
130 mm higher. Now, it is ready to work.
When neither the tap or the motor will turn, this
could be attributed to one of the previous items 2
to 6 or to insufficient motor power
• Check items 1 to 3 (page 36).
• MINIMUM pressure 6 bar (for high power and
rotation speed).
• Clogged exhaust filter (page 38).
• Clogged admission filter (in the air group) (page
38).
• Worn motor plates (pages 38).
If the tilting arm descends too far:
• Turn the regulating handwheel to the position •••
(page 36).
• If the arm continues droping, it is because the
damper is faulty. So, you will have to replace it by
a new one (page 38).
OPERATION - ANOMALIES
Ref: Slipping clucth type tap holders
The clutch slips and the tap cannot be turned:
• Clutch slackness (page 36).
• No tool lubrication.
• Inappropiate tap for the material to machine (page 37).
• Tap spoiled, “worn”.
• Misaligned hole.
• Drilled hole diameter too small.
CLUTCH ADJUSTEMENT (compensating for tap wear)
Remove small spring clip around perimeter and turn the
notched nut clockwise or counterclockwise to increase
or decrease the clutch tension and put the small ring
back on to the new notch.
