Periodic Pressure Relief Valve Check - Greenlee HK1230 Instruction Manual

Periodic Pressure Relief Valve Check

Pinch points:
Keep hands away from closing dies.
Failure to observe this warning could
result in severe injury or death.
The crimping tool's relief valve may require occasional
adjustment. To determine whether this adjustment
is necessary, periodically test the crimping tool
with a Greenlee model 35887 Load Cell (purchased
separately).

1. Insert the test dies into the tool (refer to steps 3
and 4 under "Operation" in this manual). Position
the load cell so that the load cell piston is centered
between the two test dies.
2. Pump the lever until crimping tool achieves pres-
sure relief and note the position of the needle when
the pressure relief is achieved. The needle should
indicate the "12T" range. If the needle is outside of
this range, send the crimping tool to an authorized
service center for adjustment.
Note: If some other type of load cell is used, the ratio
between the area of the tool and the area of the load cell
may be different. The appropriate corresponding pres-
sure range depends upon this ratio.
