4 GENERAL DESCRIPTION AND TECHNICAL INFORMATION The equipment consists of a pendular parallelogram balanced by a gas spring. The assembly of both secures the clamping head and keeps it in a perpendicular position to the work area. In addition, it is possible to incorporate locks (manual or pneumatic) that lock the rotation on the shaft of the base and the tilting motion of the ar.

4. Air connection (for versions with pneumatic locks L22 or L92 only). Requires suitable piping tube for use with compressed air. (Ø = 6 mm and working exterior pressure 0.5 - 0.7 MPa/ 5 - 7 bar). 5. Wiring connection (for versions L92 only). To connect your 3arm® arm to the controller of your tool [See ELECTROPNEUMATIC SYSTEM p.
6 ADJUSTMENTS 6.1 BALANCING THE ARM Regulate the tension of internal shock absorber if the arm drops or has a lot of upward force. 1- Maintain the tilting arm in an approximately horizontal position to facilitate the task. 2- Using the flywheel installed for this purpose, in the upper part of the cross, rotate it as necessary.
6.2 BALANCED, CENTRED POSITION -Balanced arm position: It tends to stay in the position in which it was left free. -Centred arm position: It tends to remain horizontal once left free. It is possible to adjust the arm to achieve balanced or centred adjustment. A - BALANCED (see image below) 1- Turn the Allen screw (4 mm Allen key)
6.3 REGULATION OF THE RESISTANCE TO ROTATION. The stud in the support enable you to adjust the rotational resistance of the axe of movement of the arm. The stud with a Nylon tip can be tightened or loosened to regulate this turning resistance (5 mm Allen key).
6.4 HOW TO SECURE TOOLS WITH A SQUARE SECTION To secure the tool correctly, Tecnospiro recommends using ball-tip headless Allen studs for thrust pads. This component allows you to adjust the tool from all sides, adapting the pads to the surface of the tool.
7 OPERATION 7.1 L11 MANUAL LOCK The L11 configuration allows manual locking of different arm movements by means of adjustable handles. 1- Base radial lock 2- Arm tilting lock 3- Head lock To lock the movement, turn the handle (1, 2 or 3) clockwise. To unlock the movement, turn the handle (1, 2 or 3) anticlockwise.
7.2 PNEUMATIC LOCK L22 The L22 configuration allows you to pneumatically lock different arm movements using switches. 1- Base radial lock 2- Swing Arm lock Position of the switches to obtain one lock or another. Movements Switches Cylinder control Radial movement (X-Y plane) Swing movement (Z-X plane)

7.3 L92 PNEUMATIC LOCK L92 PNEUMATIC LOCK - Failing to use telescopic compensators could cause malfunction or premature wear of the pneumatic locking system. - To configure L92 it is advisable to use telescopic compensators [See L92 PNEUMATIC LOCK: USE WITH COMPENSATORS p.
Page 28
7.3.1 L92 PNEUMATIC LOCK: USE WITH COMPENSATORS The use of telescopic compensators allows screw-mounting or tightening in any position (V- Vertical, H-Horizontal, A-Angle) with the arm completely blocked. For the use of compensators in your 3arm arm, follow these instructions. 1.
Page 29
7.3.2 L92 PNEUMATIC LOCK: USE WITHOUT COMPENSATORS The configuration L92 allows different arm movements to be locked through the activation of the tool or, failing that, the electrovalve. 1- Base radial lock 2- Swing Arm lock Below, the movements that are locked and unlocked depending on the position of the switch when the tool is operated.
Page 30
Depending on the Vertical (V) or Horizontal (H) work that is going to be carried out, you must position the switch as shown in the image. If working in A (angle), the switches must be positioned at V (vertical) if a more vertical than horizontal position prevails, or otherwise H (horizontal).
Page 31
7.3.3 L92 PNEUMATIC LOCK: MANUAL ACTIVATION When the wheel on the cover is operated (Versions L92), the arm's pneumatic lock is activated. The wheel has to move from position 1 to 2. To do this, apply a slight rotation, with your hand, as indicated in the diagram. 1- Wheel extended, arm free.

8 MAINTENANCE The arm does not require maintenance and, when used properly, anomalies are unlikely to occur. Even so, the main, simple repairs that you can do are set out. 8.1 COMPRESSED AIR MAINTENANCE UNIT For good functioning of the compressed air unit, an air quality level of class 1.4.1 is recommended, according to the table attached.
8.5 REPLACING THE GAS SPRING PRIOR TO REPLACING THE GAS SPRING ✓ The equipment must be duly installed and integrated. ✓ Disconnect the pneumatic supply from the equipment. ✓ It is advisable to dedicate two operators to this task. ✓ If the arm has a double spring, in the event a fault is detected in one of the two, both springs must be replaced.
Pay special attention to the position of the shock absorber within the groove of the arm shaft. If the shock absorber is single, mount it in the groove indicated with the notch (1), however, if the shock absorber is double, mount it in the grooves not marked with the notch (1). In turn, mount the "concave"...
8.7 REPLACING THE HEAD BEFORE REPLACING THE HEAD ✓ The equipment must be duly installed and integrated. ✓ Disconnect the pneumatic supply from the equipment (if connected). ✓ It is advisable to dedicate two operators to this task. 1. Remove all tension from the shock absorber (1) [See BALANCING THE ARM page 19].
8.8 REPLACING RADIAL PADS L11 BEFORE THE REPLACEMENT ✓ The equipment must be duly installed and integrated. 1- Loosen the handle (1) and remove it. 2- Loosen the stud (2) (1.5mm Allen key), untwist the cover (3) and take out the pusher (4). 3- Remove the safety ring (5) and use an M4 extractor to remove the pins (6).
8.9 REPLACING TILTING PADS L11 BEFORE THE REPLACEMENT ✓ The equipment must be duly installed and integrated. 1. Loosen the studs (1) (2.5 mm Allen key) from the bottom of the arm. 2. Unscrew the brake assembly (2) with a compass wrench. 3.
