The Air Driven Sewer Pipe Tapping Machine is powered by a 1.75 horsepower motor. Operation is as simple 

as attaching the air hose from your compressor or other source to the end of the trigger handle. Care should be 

taken to ensure the holesaw and pilot bit have been properly connected before attaching the Sewer Pipe Tap-

ping Machine to a power source. 

INSTALLING PVC ADAPTER, PVC PILOT & PVC HOLESAW

The PVC adapter, which mates the PVC pilot and 

PVC holesaw to the Sewer Pipe Tapping Machine is 

easily installed by inserting the cutter screws up through 

the 7/16” holes and threading them into the main swivel 

housing. Next thread the PVC pilot into the end of the 

PVC adapter and tighten. Thread the Jam Nut onto the 

end of the PVC adapter until it bottoms out on the back 

of the threads, then turn it back one to two turns. This 

allows the Jam Nut to be backed away from the holesaw 

when removing the holesaw after the cut.

tipped pilot and diamond tipped holesaws. 

Damage to the pilot bit and holesaw will re-

sult if water is not used while cutting.

Connect the water tank quick disconnect 

to the nipple sticking out the side of the bear-

ing housing. Make sure the nipple is sticking 

through the eye bolt thatʼs threaded into the 

gearbox.  Pressurize the water tank by using 

the pump handle on the tank.
