Operating Instructions
CAL 36/4 (810587) and CAL 40 (810477) Adjustable Torque Screwdrivers
Sturtevant Richmont adjustable torque screwdrivers are designed and manufactured to provide consistent
user-settable torque in varying assembly or maintenance applications. These tools meet or exceed
ASME B107.300-2010 and ISO 6789 specications of +/- 6% preset value accuracy from 20% to 100% of
capacity, and +/- 1.2% of capacity below 20% of capacity. These tools meet or exceed this requirement in
both the clockwise and counter-clockwise directions.
S/R adjustable torque screwdrivers signal the operator that the torque setting has been attained by emitting
a distinct audible and tactile impulse (click”). These adjustable torque screwdrivers do have graduations
and the torque must be set to the desired level before use.
Cautions
• Always wear appropriate safety equipment when using any hand tool.
• Only use hand tools for their intended purpose.
• Never exceed the rated capacity of the tool.
