Your B1-4 electric gummed tape dispenser is completely assembled, except for the water bottle, bottle support, and tape roll center shaft, which have been packed separately for shipping.

  1. Lift Sliding Door #11 from its track, and remove the water tank and brush.  Wash the new brush with warm water and soap to get good moistening action.  Replace this assembly with the longer bristles of the brush toward the front of the machine.  Squeeze the sides of the brush together a little when sliding the tank and brush in to prevent the bristles from sticking out the sides of the tank and “wicking” water out of the tank.
  2. Insert the foot of Bottle Support #26 into the clip on the left side of the machine.  (See diagram 1).
  3. Fill the water bottle preferable with warm water, and insert the tip of the cap into the tank filler hole.  Lean the bottle back into the bottle bracket. (See diagram 2)

  4. Adjust the (2) Tape Roll Guides #27 to accommodate the width of tape used.  Place Center Shaft #29 through the core of the tape roll, and place the ends of Center Shaft #29 in the notches on top of the Tape Roll Guides, so the tape is supported by, and rotates freely on, the Center Shaft.  The tape roll must ALWAYS be supported on the center shaft in this manner to feed the tape smoothly, and prevent jamming, and overloading the motor.
  5. Insert the smooth, flat, and square end of the tape between the Upper and Lower Rear Guide Plates #4 & 5 until the end of the tape just touches the back of Cut-off Blade #63.  Make sure the tape is centered and straight in the machine.
  6. Remove Top Cover #2.  Screw Operating Lever #52 into Rocker Arm #50.  Replace the top cover.
  7.   Plug the power cord into a GROUNDED 115 volt outlet.
  8. TO OPERATE THE DISPENSER, simply push the Operating Lever back as far as it will go, and hold it until the desired length of tape is fed out.  Release the handle to cut off the tape.

If the tape is too dry, loosen Screw #219 on the side of the water tank and raise Adjusting Plate #23 to increase the water level.  If the tape is too wet, lower adjusting plate #23.


Remove and wash the moistening brush with soap and water frequently to remove glue deposits, which may hinder the moistening action.

The Cut-off Blade #63 is designed for easy removal for cleaning, which should be done frequently to ensure proper cutting action, and prevent jamming.  Fine steel wool or a scouring pad may be used to clean the blade.  The blade is VERY SHARP – handle it carefully!

To remove the blade, UNPLUG THE POWER CORD.  Remove Top Cover #2.  Lift Weighted Guide Plate #9 to unhook its turned-up back edge from under Crossbar #33, and remove the plate.  Push Operating Lever #52 back and slip blade off Rocker Arm #50.  To replace the blade, reverse this process, making sure the “FRONT” label faces the front of the machine.  Hook the upturned back edge of the Weighted Guide Plate is hooked under Crossbar #33, with the weight is on the top front of the plate.  The Weighted Guide Plate helps hold the blade in place.

To remove the Top Rear Guide Plate #5 for cleaning, or removing the last couple of inches from a roll of tape, simply remove the (2) Tape Roll Guides #27, and pull the Guide Plate straight back from under spring-loaded Cross Bar #31.  When replacing the Guide Plate, be sure to push it all the way forward so it snaps into place under Cross Bar, and the projections on each side rest on the bottom Rear Guide Plate, providing space for the tape to slide between them.


The slot in which the blade moves must have the proper clearance.  If the slot is too narrow, the blade may stick.  If the slot is too wide, the tape may curl down before being completely cut off, so the end feeds down into the machine, causing it to jam.

To adjust the width of the slot:  Unplug the power cord.  Remove the Water Bottle, Sliding Door, Water Tank, and Weighted Guide Plate.  Loosen the (2) Screws #54 which hold the Bottom Front Guide Plate #10 (just in front of the Blade).  Move the Guide Plate forward or back to get the desired clearance.  The proper clearance is about one thickness of reinforced tape.  When the clearance has been set, re-tighten screws #54.  CAUTION—Do not tighten these screws so tightly that they strip the threads out of the aluminum side rails.


Machines sent to us for repair or adjustment must be well packed to prevent damage in shipment, which may result in additional repair costs.

Please give us a complete description of the problem. This saves diagnostic time and reduces labor charges. We need your name, address, and phone number.  Please tell us which parts, which you have NOT returned. Parts not returned with the machine will be presumed lost, and replaced with new ones unless we are informed otherwise.
