Porter-Cable FN250A instruction manual Clearing a Jammed Fastener

Page 10

Remove finger from trigger when not driving fasteners. Never carry tool with finger on trigger: tool will fire a fastener if safety is bumped.

Keep fingers AWAY from trigger when not driving fasteners to avoid accidental firing. Never carry tool with finger on trigger. In “Contact Actuation Mode” tool will fire a fastener if safety is bumped while trigger is depressed.

Never point tool at yourself or others.

Never attempt to drive a fastener into material that is too hard, or at too steep an angle, or near the edge of the workpiece. The fastener can ricochet causing personal injury.

Disconnect tool from air supply before performing maintenance, clearing a jammed fastener, leaving work area, moving tool to another location, or handing the tool to another person.

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. 26. 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 adjustment knob (A) Fig. 26: the adjustment knob has detents every 1/4 turn.

Rotate the knob clockwise (see Fig. 26), to increase the depth of drive, rotate

the knob counterclockwise to

 

 

decrease the depth of drive. Test fire

Fig. 26

 

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

A

 

consistently perform the job at hand.

 

 

 

Air pressure in excess of that

 

 

required can cause premature wear

 

 

 

 

and/or damage to the tool.
