Capacity and Use:
The "E-4" Drilling Machine drills hols from 7/16" to 1" inclusive in any size or kind of main. This is done under pressure by using a stop or valve between the machine and the main. The stop is not required when there is no pressure.
Working Pressure and Temperature:
- 500 p.s.i. Maximum working Pressure at 100℉
- 250℉ Maximum Temerature Rating at 375 p.s.i.
The working pressure or temperature rating is reduced accordingly if any attachment, valve or fitting, subjected to pressure or temperature during the drilling operation, has a maximum working pressure or temperature rating less than that specified above.
Length of Travel: 9 9/16"
Equipment Furnished with Each Machine:
- Ratchet Handle
- Body Gasket
- Adjustable Wrench
- 2 double Open End Wrenches
- Lubricating Oil
- cutting Grease
