DESCRIPTION
2.1.
Physical
The pump is a two-stage hydraulic pumping unit. It is driven by a universal motor connected to a gear pump for
the low-pressure stage and a five-cylinder axial piston pump (supercharged by the gear pump) for the high-
pressure stage. The pump features a hydraulic fluid reservoir and pressure regulation and control devices.
The hydraulic connection is fitted with a thread protector cap to prevent the threads of the quick-disconnect
coupler from being damaged and to prevent contamination of the quick-disconnect coupler.
The pump features a pilot lamp (69120-1 only) that illuminates to indicate that the pump is activated.
The pump includes casters (one for each corner) that can be installed onto the pump for portable applications.
For pump specifications, see section 2.3.
The date code is marked on a metal tag attached to the body of the pump. The date code is in the format
YYWW, where YY represents the year of the manufacture, and WW represents the week of manufacture. For
example, if the date code marked on a tool is 2133, the tool was made in the 33rd week of 2021.
2.2.
Functional
Before each cycle can be started, the RESET switch (of the handle control or foot control) must be depressed.
When the RESET switch is depressed, the pilot lamp (69120-1 only) of the pump illuminates.
When the RUN switch is depressed and held, the pump completes a cycle. When the RUN switch is depressed
momentarily, the cylinder of the crimping heads partially advances and the dies partially close for a moment.
When the DUMP switch is depressed, the cylinders retract, the dies open fully, and the pressure is released
from the system.
When maximum hydraulic pressure is reached, the motor shuts OFF, and all pressure is automatically released
from the system.
This pump is not for use in applications other than crimping. Examples of improper use include work holding,
cutting, bending, and lifting applications.
