and tear, at higher torque setting and use extensively could accelerate the wearing down of tool.
After one month, the torque is getting reduction gradually at the rate of 2~3% or 3~5 %( max
torque). The longer use of the device, torque reduction will become stable and the users could
measure the torque by a tester on a regular time schedule to check if the torque power still
meets the criteria.

Slow speed Duty Cycle Conversion (for reference)
Based on 1000 rpm, 1 second ON/3 seconds OFF. For example, the duty cycle for 350rpm,
1000-350=650
，
650/1000%=65%
ON= 1*1.65= 1.65
，
OFF =3*1.65 =4.95 (rounded value) =2 seconds ON / 5 seconds OFF
This tool is intended for a duty cycle of 2.0 sec on, 5.0 sec off.
