Marson ValueRivet V-3 User manual

General Information
The Marson ValueRivetV-3 pneumatic/ hydraulic riveting tool is
designed to set rivets in all materials in sizes from 1/8” to 3/16”
diameter. Model V-3 is supplied with 3/16” NOSEPIECE (17C)
installed in the operating position. Standard nosepieces for 1/8”
(17A) and 5/32” (17B) diameter rivets is included among the
accessories supplied with the tool.
The Maximum Air Pressure is 95 PSI At Tool.
Specifications
Rivet Setting Capacity 3/16” diameter
Traction power 1983 lbs
Operating air pressure 85-95 PSI
Air consumption 4 CFM
Air Inlet 1/4” N.P.T.
Overall height 11”
Net weight 3.3 lbs.
Accessories
The V-3 is packaged in a compartment storage container.
Wrenches needed to service the tool are included. Special
SPANNER (40) has a cut-out gauge used in adjusting the tool as
described below.
Also included: Safety Cap (49) to catch ejected mandrels when
attached to the back of the tool.
Maintenance
In order to achieve maximum efficiency and economy, the Marson
V-3 pneumatic/hydraulic riveting tool should be serviced and
maintained on a regular basis. No special skills or tools other than
the ones provided are needed to properly service and maintain the
device.
The operative parts of the tools requiring regular inspection and
maintenance are as follows:
1. The JAWS (2) should be periodically inspected, cleaned, and
when necessary, replaced with new jaws (see Cleaning and
Changing Jaws under Procedures below).
2. The FRAME (14) of the tool should be checked periodically to
ensure that the oil level is maintained and that there are no leaks
or breakdowns in the seals. (See Repair sections under
Malfunction for procedures).
Maintenance Procedures
1. Cleaning and Changing Jaws
IMPORTANT – Disconnect the V-3 from the air pressure line
before proceeding with inspection or repairs. Use SPANNER (48)
to remove HEAD (16) and JAW HOUSING (1). At the same time,
hold the JAW CASE COUPLER (4) with 14MM WRENCH (13).
Clean jaws with solvent or a steel brush. Replace with new jaws if
excess wear is apparent. Always coat outer or smooth surface of
jaws with an oil film before assembling.
Reassemble by reversing order of above procedure. It is important
that JAW PUSHER (3) engages the conical parts of the JAWS. DO
NOT CHANGE THE POSITION OF PARTS (4) and (6). If these
parts are inadvertently changed, see readjustment instructions under
“Malfunction.”
2. Changing Nosepiece
Connect V-3 to air pressure and press TRIGGER ARM (39) until
nosepiece has been removed and new nosepiece fully tightened.
When TRIGGER ARM (39) has been released and tool is at rest there
should be a circular opening visible in the nosepiece.
Malfunction
1. Mandrel gripped by JAWS (2) but rivet does not set and
mandrel does not break:
CAUSE: Low air pressure or loss of oil.
REPAIR: Increase air pressure but do not exceed 95 PSI at tool.
Make sure all fittings including FRAME CAP (10) and HEAD (16)
are tight. If malfunction persists, add oil as follows:
Disassemble AIR CYLINDER (28), FRAME (14) and HEAD (16).
Before adding oil, check to be sure OIL PISTON (7) is at the bottom
of its stroke, by hand pulling JAW HOUSING (1) away from
FRAME (14). OIL PISTON (18) should bottom its stroke
automatically when removing FRAME HEAD (16). If JAW
HOUSING (1) moves downward by hand power, then RETURN
SPRING (11) must be replaced. Care must be exercised to avoid
damage to O-RING (46). Pour MARSON OIL No. 39105 or
equivalent into FRAME (14) while tool is upside down. Before
assembling also check for oil appearing in AIR CYLINDER (28) or
HEAD (16). If oil is found in any of these areas, replace O-RING
(12, 46) as needed. Reassemble tool.
2. Mandrel does not enter nosepiece OR fails to eject.
CAUSE: JAW HOUSING COUPLER (4) and NUT (6) have
changed position.
REPAIR: Adjust so that the distance between the plane underside of
the FRAME (14) and the front edge of the securely-assembled JAW
HOUSING (1) is approximately 2-3/8”. This can be measured with
the cut-out gauge on SPANNER (48) before assembling HEAD (16).
3. Tool takes more than one stroke under ideal conditions to set
rivet and break mandrel.
CAUSE: Insufficient oil.
REPAIR: See repair instructions under Malfunction, 1.
CAUSE: Not enough air pressure.
REPAIR: Increase air pressure but do not exceed 95 PSI at tool.
CAUSE: Loose nosepiece.
REPAIR: Tighten nosepiece with SPANNER (48).
CAUSE: JAW HOUSING COUPLER (4) too far forward.
REPAIR: See procedure under Section 2 above.
