11. Set Pull and Return pressures on Powerig
using Huck Gage P/N: T-124833CE and
Table 1.
12. Using a load cell (see P
HOTO-A) or a skid-
more, and a test fastener in the tool, energize
the Powerig using a trigger switch. Adjust the
Relief Valve (see P
HOTO - B) so the tool gen-
erates the Tool Force shown in Table 1 below.
This is a direct force reading, not pressure. It
equals approximately the Relief Valve
Pressure shown in Table 1
. NOTE: It is
important to Release the Trigger while
adjusting pressure, then re-energizing to
re-check pressure. Otherwise, the reading
on the pressure display may be incorrect.
When the desired pressure is achieved,
reconnect the Controller Cord.
13. Tool #2 and Tool #3 - Set up the same way as
Tool 1.
14. Once the system is set up, Install test fasten-
er. Check to be sure that the fastener is
installed correctly. This can be checked by
inspecting the dimples on the collar flange. At
least one dimple should be marked by the
anvil. If not, add time to Timer #2 (Hold Timer)
in the Controller box, and test with fasteners
until the proper installation is achieved. See
“Set Point Adjustments” in C
ONTROLLER sec-
tion on the next page to adjust timer.
