Singer RN175A instruction manual Clearing a Jammed Fastener

Clean and inspect tool daily. Carefully check for proper operation of trigger and safety mechanism. Do Not use the tool unless both the trigger and the safety mechanism are functional, or if the tool is leaking air or needs any other repair.

The depth to which a fastener is driven is controlled by the depth adjustment knob (A) Fig. 28. The depth of drive is factory adjusted to a nominal setting. Test fire a fastener and check depth. If a change is desired, rotate the knob

(A)Fig. 28 clockwise to increase the depth of drive, rotate the knob counterclockwise to decrease the depth of drive. The adjustment knob has detents every 1/4 turn. Test fire another fastener and check depth. Repeat as necessary to achieve desired results. The amount of air pressure required will vary depending on the size of the fastener and the material being fastened. Experiment with the air pressure setting to determine the lowest setting that will consistently perform the job at hand. Air pressure in excess of that required can cause premature wear and/or damage to the tool.
