Operation
The automatic taper simultaneously applies tape and joint compound to any joint: walls,
corners, and ceilings. It automatically dispenses the correct amount of joint compound
under the tape, regardless of the tool user’s speed.
The automatic taper uses tape 2 1/16” to 2 ⅛” (52-54 mm) wide. Wider tape will not fit and
narrower tape may have a tendency to jam. Install the tape by removing the tape bail (retaining
wire) and placing the roll of tape on the spindle with the tape unwinding clockwise as you look at
the roll. Feed the tape through the tape guide with the back side of the tape facing down. When
correctly installed, the tape will curl over the drive wheel.
Fill the automatic taper with joint compound using the EasyClean® Loading Pump and the gooseneck
assembly. Be sure that the gate control lever is in the closed position. Place the automatic taper on the
gooseneck with the filler attachment firmly seated against the nylon seal and move the EasyClean® Pump
handle to transfer joint compound from the pail to the automatic taper. Keep the joint compound bucket
full to avoid air being pumped into the taper. To avoid overfilling the taper, place your fingers in the open
end of the tube while filling. Stop pumping when the piston reaches your fingers (approximately 9 pumps
when empty). After loading the automatic taper, stand it on end and move the gate valve control lever to
engage the drive mechanism. Now turn the drive dog, located on the drive gear sprocket, until the joint
compound covers the leading edge of the joint tape. This is necessary after each loading.
The automatic taper should be held with one hand on the control tube and the other hand at the bottom
of the mud tube.
Start taping with butt joints first and then sidewall and ceiling flat joints. For ceilings, use both drive
wheels for the first 4 - 6 inches (100-150 mm) of tape to secure it to the ceiling, then tilt the automatic
taper toward you at a slight angle leaving only one drive wheel on the drywall surface. Walk backwards,
leading with the head of the tool.
To tape vertical joints, place the taper at the bottom of the joint, parallel to and slightly above the floor.
Lead with the head of the taper, as soon as possible to make tracking easier. Remember to roll with only
one wheel in contact with the wall until about 3 inches (75 mm) from the top. Stop completely, cut the
tape, by pulling the control tube toward you, and roll to the end of the joint on both wheels. To start the
next joint, move the drive wheels lightly against the surface of the wall, starting the compound flow while
advancing a new end of the tape with the control tube.
To tape horizontal joints, advance the joint compound and about 1 ½ inches (40 mm) of tape by pushing
forward on the control tube while rolling the drive wheels on the wall. Place drive wheels on the wall and
roll along the joint. Stop about 2 ½ inches (60 mm) from the end of the joint and cut the tape. Roll out the
last 2 ½ inches (60 mm) of tape while feeding tape with the control tube. This will apply compound to the
beginning of the tape for the next joint.
