Symptom
Remedy
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.
• Check Depth Control screw setting as it may be too long.
Screw inserts but does not go
in all the way
• Confirm the bit is the correct length for the attachment.
• Check to be sure that collars on the depth control/nose
pieces screws are seated correctly (see Set Up,
Depth Control Adjustment).
Screw strip falls forward out
of belt guide when tool is
raised into position
• Turn orange knob attached to the front of belt guide
to increase tension.
Screw does not countersink
properly
• Turn countersink adjustment ring until the proper
countersink is achieved.
• Check bit to be sure it is the right type and length.
Screw tip drags on surface
before installation of screw
• Screw tip is likely beyond the outside of the Depth
Control. Adjust Depth Control until screw tip protrudes
halfway into Depth Control Throat.
First few screws advance then
the belt stops moving
• Loosen tension control on the belt guide to allow
movement.
• Check gear wheel movement as described under
Cleaning and Repair.

Symptom
Remedy
Gliding piece will not retract
fully into housing on down-
stroke
• Check that screws holding Depth Control in place are
fully seated into cut outs.
Gliding piece jams or is
difficult to move in the
housing.
• Check first that there are no burrs on the front of the
housing that are interfering with the movement of the
gliding piece.
• Check the width of the housing opening to ensure that
a bump or blow from something else has not forced the
front of the housing inward.
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
down-stroke will cause bit tip to lose full contact with
screw recess and potentially strip out recess.
Jammed fastener
• Stop motor.
• Pull screws completely through Gliding Piece.
Reinsert in belt guide and gliding piece.
• To avoid jamming, be sure motor is running before
down stroke begins.
Screw becomes jammed in
Depth Control, gliding piece
or housing
• Remove the fastener and test the tool.
Most of time the jam will cause no damage.
