WARNING
3. TESTING
3.1. Test Ram/Pump set-up
To verify Ram/Pump set-up, step on the end of the
pump pedal marked "PUMP"
while watching
the Hydraulic Ram. Within a few seconds, the Ram
should begin to stroke. Note that the piston strokes out
of the back of the hydraulic Ram. If the Ram does not
stroke, check all connections, the oil level and repeat
this step.
Proper operation will be indicated by cylinder of the ram
extending 1” – 3” (25.4 to 76.2 mm) (model dependent)
followed by the pressurization indicated on the gauge
increasing to 7500 PSIG (517 BARG).
3.2. Release Pump pressure
While holding the Ram handle step on end of the Pump
Pedal marked "
RELEASE
".
This will allow
the piston of the Ram to retract.
To remove the pneumatic power to the equipment,
disconnect the pneumatic quick connect.
4. OPERATION
Assemble the ram head with the pullrod assembly in accordance with
DC1220
or
DC4000
: Pop-A-Plug installation
instructions. Follow Pop-A-Plug installation instructions.
DURING RAM OPERATION, THE SAFETY CABLE MUST ALWAYS
BE ATTACHED TO THE PULLROD.
NEVER LEAVE THE EQUIPMENT UNATTENDED WHILE
CONNECTED TO A PNEUMATIC PRESSURE SUPPLY.
NEVER DISCONNECT THE HOSE FROM THE RAM OR PUMP
WHEN THE EQUIPMENT IS PRESSURIZED.
5. CLEANING AND MAINTENANCE
The Ram system should be cleaned of all dirt and oils after ever use. Keeping the Ram Kit components wiped free of
debris before and after use will lessen the chances of foreign materials entering the hydraulic or pneumatic system
and extend the life of the equipment. Change hydraulic oil every 300 hours of use approximately; use Power-Team
AW Hydraulic Oil ISO-46.
There are no serviceable parts on the Ram Kit. Contact EST Group for any repair or replacements of components.
