parallelograms which are balanced by
pneumatic springs and a two-rotation
axis head. This group fixes the motor
and keeps it perpendicular to the
working area.
El motor is equipped with a module
quick-change system, and rotates by
compressed air, that has previously
been filtered and lubricated by a unit
for that purpose.
Taps and shank tooling fit directly
to quick-change tapholders.

The ROSCAMAT-500 can be supplied with an articulated head (C-26
N). This bracket of easy handling can be set in four different positions 90º
apart.
Orientable head:
1.- Handle
2.- Milled nut
Vertical operations:
Place the motor in vertical position and lock the handle (1) and the milled
nut (2). The ROSCAMAT now is ready to work.
Horizontal operations:
Loose the milled nut (2) to unlock the joint of the motor.
Turn the head 90º till you reach the interlock, and then tighten the millet
nut (2) again.
Unlock the handle (1) located in the upper side of the head.
When moving the arm, the operator will have to manually maintain the
perpendicularity to the working plane.
Do not lock the handle (1) if you are working in horizontal operations.

DESCRIPTION
AUTOMATIC TAP LUBRICATOR EQUIPMENT (E)
The machines of the model ROSCAMAT 500 E / 500 (C26 N) E /500 RH E,
incorporate an automatic tap lubrication system.
The oil reservoir is arranged inside the radial arm and is connected to an
innerly arranged hydraulic cylinder. The desired cutting oil flow rate is
adjusted by means of ten control valve (3). When pressing the motor lever the
system pumps the flow rate in the pump being arranged the tilting arm.
After having filled the oil reservoir, immediately bleed the system by applying
pressurised air through the hole being provided in the filling cap (1) of the
reservoir.
*Caution: USE CUTTING OIL
Certain lubricant types containing trichlorines and alcohols can damage some
of the valve components.
1.- Filling cap
2.- Drain screw
3.- Regulation valve
4.- Articulated pipe

12
INSTALLATION
A : Mount the machine base plate on to the working table by means
of three M8 screws or the clamp.
B : Fill up the reservoir (6b, page 10) with lubricating oil SAE-10.
C : The air connection is carried out by means of a notched
connections (17, page 4 y 14, page 6 ) located on the machine
base.
IMPORTANT:

13
INSTALLATION VERIFICATION
Once the machine has been connected to the main, have to be checked:
1. Supply pressure:
6-8 bar for full power
2. The pressure gauge reading can drop 0,5 maximum 1,5 bar when the
motor is started (if a drop greater than 2 bar is noticed, this means that
the supply flow rate is not sufficient).
3. Make sure, by checking the sight glass (8b, page 10) 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 10).
4. Arm balance:
By turning the regulation handwheel (11 and 14, page.4) and (4 and 6,
page.6) to the right (-) or to the left (+) different weight at the arm end
are balanced.

14
OPERATION
1. Turn the slide collar (4, page 10) to the left, insert the module and turn
the slide collar to the right.
2. Regulate the arm balance for the 90 and 170 modules.
3. Insert the tapholder in the quick change of the module.
4. Clockwise rotation: push lever (1, page 10)
5. Counterclockwise rotation: push simultaneously lever (1, page 10) and
button (2, page 10).
6. Pulling up the tool quick change (6, page 10) the tapholder will come
out automatically.
SPEED CONTROL - CONSUMPTION CONTROL

OPERATION ANOMALIES
Slipping clutch type tapholders. The clutch slips and the tap cannot be
turned.
1. Clutch slackness. Clutch adjustment (page 15)
2. No tools lubrication. Use cutting oil.
3. Inappropriate tap for the material to machine. Use the correct tap. (page
16).
4. Tap spoiled “worn”.
5. Misaligned hole.
6. Drilled hole diameter too small.
When neither the tap or the motor turns, this could be attributed to one of
the previous items 2 to 6, or to insufficient motor power.
1. Check items 1 to 3 (page 13).
2. MINIMUM pressure 6 bar (for high power and rotation speed).
3. Clogged exhaust filter (page 19).
4. Worn motor plates (pages 20 y 21).
If the pivoted arm drops:
1. Arm not balanced. Check item 4 (page 13).
2. Faulty damper. Substitution (page 22, 23).
If the lubrication system don’t work:
1. The oil tank is empty. Fill the reservoir ( page 11)
2. The oil-hole is clogged. Introduce a un a 0,3-0,4 mm wire through the
oil-hole.
Upon having filled the oil reservoir immediately bleed the system
(page 11)
CLUTCH ADJUSTMENT
Remove small spring clip around perimeter and turn the notched nut
clockwise or counter clockwise to increase or decrease the clutch tension and
put the small ring back on the new notch.

MAINTENANCE
Practically the only machine’s part that we can wear is the motor.
Therefore its maintenance should be carried out very carefully, which means
that the air supply must be in dry & clean condition. For this purpose, the
following three points must be taken into account:
1. Drain periodically the water collected in the left air treatment
unit cup by pressing the relief knob (5b, page 10).
2. Fill up the right air treatment unit cup with SAE-10 (light duty
oil).
3. Check through the sight glass (8b, page 10) that when the
machine is in operation, two or three drops per minute are
supplied. The regulation is made by means of the control knob
(7b, page 10).
WARRANTY
The warranty period for the motor and for the rest of the machine is one
year. The warranty does not cover any damage caused by overloads or
improper handling of the machine.
