Proper Use

Vacuum Pressure

Important Note

The TBV-2001 "2n1" is a hand held vacuum gun designed to operate at 80psi (5.5 bar) and has two settings:
1) Suction
2) Blowing
The 5/16" x 6" long flexible nozzle can reach under feed-dogs, behind looper and other hard to reach areas of sewing machines and other equipment.  Vacuum or blowing function is activated by depressing a trigger with index finger. The 2n1 vacuum guns convert from blowing to vacuum function by turning the function dial located on the front housing of the gun.  Air and debris exhaust into a removable filter bag and oil cup attachment that contain the oily dust and lint.  The 2n1 vacuum gun meets OSHA's requirement of 30psi for blowing function at 80psi (5.5 bar) inlet pressure.

Proper use of TBV-2001 "2n1" Vacuum Gun:

Industrial sewing machines and equipment should be cleaned daily.  Cleaning machines twice a day is recommended, once at mid-day and again in the afternoon before the operator goes home.  You should start with a clean machine and implement a daily cleaning schedule to maintain a clean machine that will be free of the oily lint and debris to eliminate oil stained garments.  You should never use compressed air to blow out machines when cleaning, as this method will simply cause the oily lint and debris to migrate on to your finished garments leaving them stained with oil spots.  The light blowing function of the 2n1 vacuum gun is designed only for blowing dry dust and lint from table surfaces or operator clean up.  Blowing machines out with compressed air can also be a safety hazard to the operator and other personnel nearby.

The 6" long x 5/16" OD. nozzle is not designed to accept large pieces of hardened oily lint or debris that is greater than 3/16" in diameter.  For this reason it is important to start with a clean machine and implement a daily cleaning schedule of all machines.  Debris larger than 3/16" in diameter could become lodged within the nozzle or vacuum chamber in the gun.  If debris is lodged inside gun or nozzle, simply turn function dial to blowing function, point the nozzle down at floor and activate the trigger to dislodge the debris from gun.  If this does not work use a long pipe cleaner to dislodge the debris.

Vacuum Pressure

The TBV-2001 Vacuum Gun will pull between 12 and 13 inches of mercury vacuum at an inlet pressure of 80psi (5.5 bar). Operating the vacuum gun at air pressures less than 70psi (4.9 bar) will reduce the vacuum pressure and performance of the 2n1 vacuum gun accordingly.  Inlet air pressures above 90psi may cause internal damage to the gun resulting in air leakage around the inlet port and trigger.

Important Note

When used properly and as designed for daily cleaning and maintenance of your sewing machines and equipment the TBV-2001  "2n1" vacuum gun is an excellent machine cleaning device and will perform as intended.
