Torque Reference Charts
The charts are meant to be used as guidelines for setting torque. The drivers have
a torque scale on the torque adjustment nut showing reference numbers. These
numbers determine the approximate torque setting.
Z = Bronze
S = Silver
Accessory
The torque cover protects the K-Series from incidental or operator tampering of
torque setting.

Testing Power Tools:
1. Application Method: Use a torque analyzer in “Peak Mode” with a rotary transducer
between the power tool and the actual application. This is the best way to test since
you are using the actual joint as the test station. You will see the actual
torque applied to the fastener.
Caution:
Variances in tool performance may occur do
to the addition of the rotary transducer.
2. Simulated Method: Always use a quality joint rate simulator (run down adapter) with a torque analyzer when testing power
tools in a simulated application. Use Joint rate and Breakaway methods to obtain most accurate torque readings in a
simulated rundown.
Maintenance Intervals:
The number of cycle shown on the table below should be used as a guideline for effective maintenance in order to reduce
unexpected down time. Maintenance intervals may be determined by the several approaches: number of cycles in use,
number of hours in use, type of joint, torque and calender time. All these factors should be considered for the best
preventative maintenance. The following inspection and replacement intervals will vary depending on tightening load and
cycle-on time.
