3.1.2 ' Drive Mechan 1sm Installation h .
3.1.2.1 Start the air motor before attaching it to the cutter drive assembly to verify that it is e operating correctly. Use an ARO Model 225/275 ,
a.
RPM air motor or its equivalent. '
3.1.2.2 Prior to cutting, place a reference mark on the sleeve and the distance recorded so that once the cut is made there is a means for detemining i
} how much the sleeve has been shortened. ;
3.1.2.3 To install the weld cutter a'ssembly (Piece No.
.693-3201) slide assembly over the heater so that is engages the cutter holder (Piece No. t 6g3-3202) and install the sockot head cap screws (PieceNo. 693-3211). ;
3.1.2.4 Attach the air mater to the drive asserbly at .
Piece No. 693-3213. Start the air motor and :
apply gcntle force (approximately two (2) !
pounds initially) to the assembly to advance .
, the cutten into the weld to be removed.
- 4 I
' 3.1.2.5 Visually check progress and continue cutting i until one of the following occurs:
a) The heater is freed from the sleeve; or i b) The heater sleeve has been shortened by i approximately 1/16 inch. * '
- c. L 3.1.2.6 If. the heater sleeve is shortened 1/16 inch before' the heater is free, remove the cutter- ,
assembl pounds)y:and apply aassen61y to the heater pull (up tototwent;y (20) try to renove ;

i 3.1. 2. ;' If pulling does not free the heater, and'if the- ' i heater sleeve has been shortened 1/16 inch, replace ~
the. cutter assembly on the heater. Advance the adjusting screws evenly until a tight fit is . ,
