Autofeed Operating Tips
- » Bit should be approximately the same length as aluminum housing, or,
- » With attachment installed, bit tip should be visible after approximately 3/8” of travel by the Gliding Piece. If bit is visible before depressing nose, bit is too long. If it is not visible after 3/8”, bit is too short.
- » Ensure bit type (Phillips or PAMDrive) matches screw recess
- » Adjust the Depth Control for the length of screw (sizes stamped on Depth Control). Be sure that the collars of the screws holding the Depth Control sit down in the cutouts.
- » Place the attachment on the adapter and lock it with the wing screw.
- » For rough adjustment of countersink for new screw size, fully depress the Gliding Piece and adjust the countersink adjustment ring until the tip of the bit protrudes 3mm (1/8”) beyond the tip of the Depth Control.
- » Insert screw strip into the belt guide. Feed the screws into the gear wheel and push forward until the last open hole (adjacent to the first )the screw is centered in Depth Control. (This tool feeds on the down stroke, so if the first screw is in the Depth Control, it will be wasted when the tool begins operation.) Ensure the tip of the screw sits approximately half way through the end of the Depth Control throat.
- » If the strip falls forward from the weight of the screws, adjust the belt tension to just hold it in place. If it is necessary to remove screws, pull strip forward, not backwards.
- » Make sure the motor switch is set on forward! Lock the motor on full speed. Push the depth control against a piece of scrap material to drive the first screw. Use sufficient and continuous pressure to make sure screw is in contact with surface, but let the screw do the work. Make any final countersink adjustments. Each click of the ring equals 1/64”.
Cleaning And Repair
- » Clean gear wheel and gliding piece with compressed air, do not use solvent.
- » Lubricate gear wheel with graphite, do not use oil.
- » Gliding piece must move freely in the aluminum housing Check periodically for damage. If burrs or obstructions are found, smooth with a file.
- » Gear wheel must turn free and lock at each position. Roll wheel forward until it clicks then put pressure backwards with your thumb. Gear wheel must lock in all positions. If it does not lock, Gear Wheel is likely damaged and needs to be replaced.
Trouble Shooting Tips
- » Motor turns and bit engages, but screw does not insert or falls to the side when tool is raised – Check that motor reversing switch is in forward position;
- » Screw inserts but does not go in all the way – Check to see that the bit is the correct length for the attachment (See hint above or look on hex flat of bit for number – 2120 or 2140). 2140 bit is for 1” to 3” attachment and 2120 bit is for 1”-2” attachment(see Set up); Another hint – 1”-3” attachment has ribbed housing and 1”-2” housing has smooth sides on housing.
- » Screw strip falls forward out of belt guide when tool is raised into position – Turn thumbwheel attached to belt guide to increase tension;
- » Screw does not countersink properly – Turn countersink adjustment ring until the proper countersink is achieved; or Check bit to be sure it is the right type for the screw recess being used;
- » Screw tip drags on surface before installation of screw - Screw tip beyond the outside of the Depth Control so adjust Depth Control until screw tip protrudes half way into Depth Control Throat;
- » First few screws advance then the belt stops moving – Lighten tension control on the belt guide to allow movement, or check gear wheel movement as described under Cleaning and Repair;
- » Gliding Piece will not retract fully into housing on downstroke – Check that screws holding Depth Control in place are fully seated into cut outs;
- » If jamming occurs, stop motor, pull screws completely through Gliding Piece and reinsert in belt guide and gliding piece.
- » To avoid jamming, be sure motor is running before downstroke begins.
- » Screw is inserted only part way before bit tip starts to spin in recess – Maintain constant downward pressure while screw is being inserted. Too little or inconsistent pressure on downstroke will cause bit tip to lose full contact with screw recess and potentially strip out recess.
