USE
Air supply connection
For correct use of the pneumatic tool, always keep to a maximum pressure of 6.2 bar, as measured at the tool inlet. Feed the
pneumatic tool with clean, condensate-free air (picture 2). Excessively high pressure or humidity in supply air results in shorter
life for the mechanical parts and may damage the tool.
Interchangeable nozzle installation
The interchangeable nozzles, which are supplied with the air riveter, must be chosen according to the size and type of rivet to
use. To install an interchangeable nozzle, screw it on the nozzle holder of the air riveter (picture 3). To replace a nozzle, take
the following steps:
• Slightly loosen the nozzle holder to make it easier to replace the nozzle (picture 3).
• Remove the nozzle and fit in the required one; tighten the nozzle and lock the nozzle holder. Then operate the air riveter.
Nail collector installation
The air riveter is fitted with an automatic suction system. The nail collector must be installed, to ensure safe riveting operations; nail
ejection may cause damage to anyone working or standing near the work area. The nails should be disposed of environmentally
friendly.
The nail collector must be placed at the back of the air riveter and tightened by hand (picture 1).
Start
Start operating the air riveter, opening the air tap (picture 6). Fit the rivet into the nozzle, and press the lever (picture 3b), until
the rivet nail is sheared off. The rivet shearing time depends on the size and type of rivet used.
Periodically – notably depending on the frequency of use – clean the clamps to remove any impurities and ensure proper
operation.
Clean the clamps as follows:
• Remove the nozzle holder, using a 24-mm wrench (picture 3).
• Remove the clamps holding cone, using a 15-mm and a 17-mm wrench, and pull out the clamps.
• Then clean the clamps, using the brush the air riveter is supplied with. If the clamps are particularly worn, they should be
replaced (clamps + cone).
• Fit the clamps into the clamps holding cone; install the cone, locking it with the wrenches.
• Then screw in the nozzle holder, tightening it by hand with the 24-mm wrench.
While cleaning the clamps, also check that no oil is leaking near the oil pressure piston. If too much oil is leaking, send the air
riveter to the repair centre.
Head unit adjustment
Periodically – notably depending on the frequency of use –, and after cleaning or replacing the clamps, adjust the head unit
(picture 5). Take the following steps:
• Remove the nozzle holder, using a 24-mm wrench.
• Check the distance of the head unit with the template/wrench; the distance should be approximately 71 mm.
• Adjust the distance using a 17-mm wrench on the hexagon nut (picture 5).
• Install the nozzle holder, tightening it by hand with the wrench.
Always disconnect the air supply before replacing the nozzles or making any adjustments: this precaution will prevent the
pneumatic tool from being accidentally started.
Filling up oil pressure circuit with oil
After a long operation period, and, in particular when the cylinder stroke gets shorter, the oil pressure circuit may need to be filled
up with oil. This operation should be carried out by trained personnel; please contact Beta Utensili's repair centre, if need be.
