)
General Information
This manual contains operating and service procedures
for the Ebbert Rivet Tool models ERT1S, ERT2S,
ERT3S, ERT4S, and their optional tool configurations.
It is suggested that close attention be directed to the
recommended service procedures in this manual.
Specific instructions for each tool are given under that
tool model number heading. While they may appear to
be similar, each tool contains parts not used on other
models, and removal and replacement methods may
vary.
Principle of Operation
Incoming non-oiled plant air is regulated at 90psi
through the Air Filter/Regulator to the Four-way Valve on
the Power Unit and through the Red Air Line to the valve
in the rivet tool handle.
When the tool trigger is pulled, a trigger/plunger unseats
a valve ball and directs air from the tool handle back
through the Green Air Line to the Four-way Valve. The
Four-way Valve is shifted, directing air pressure through
the Blue Air Line into the Power Booster. As the Power
Booster air piston advances, hydraulic fluid is forced
through the black Hydraulic Line into the tool, forcing
the tool to retract. This delivers the necessary force to
install the fastener and break the pintail. (In the EPS1V,
the pintail then travels through the pintail collection tube
from the tool into the Pintail Collection Box.)
When the trigger is released, the Four-way Valve shifts
to its default position; air pressure returns the Power
Booster air piston to the full-back position and the tool
piston to the full-forward position. The cycle is complete.
