E.H. Wachs Part No. 02-MAN-01, Rev. A 19
Starting with the basic length of chain marked 6 (42” long section) add the necessary chain
segments to make up the proper length. When assembling the segments of chain to the basic
length be sure they are assembled male end to female end. Don’t try to join ends where
numbers come together. The lengths of the chain will engage freely if they are clean.
The chain segments are coupled with special chain connecting pins (Part No. 02-158-00)
furnished with the chain.
When connecting the chain segments it is best that they be placed on a flat surface to simplify
the joining of the links. Use the lineup pin (Part No. 02-159-00) to get the joining links in
proper alignment. When the chain links are aligned push the lineup pin out of the chain by
inserting a connecting pin from the opposite side.
4.
Turn the chain tension screw (Part No. 02-081-01) counter clockwise to move the chain
tension idler sprocket to its innermost position.
5.
Thread the assembled chain through the machine as shown in the section on Wheel Setting
and Chain Length (inside cover). Leave six inches protruding on valve end of machine –
balance of chain on other end.
6.
Place the machine on the pipe and join the open ends of the chain with a connecting pin as
shown in sketch for chain assembly (Figure 3, p. 16). To assist in getting chain square on
pipe, rock machine after chain has been connected but before it has been tightened.
caUtion
During chain connection, one person should hold cutter steady on pipe. Failure to do so could
cause serious injury.
7.
Tighten the chain by turning the chain tension screw in a clockwise direction. The chain will
be properly tensioned when the torque wrench is applied to the chain tension screw and it
registers 80 to 85 foot pounds (green line on torque wrench).
8.
Recheck chain tension frequently on large diameter or heavy wall pipe cutting.
9.
Remove lock nut (Part No. 02-014-00) and driving collar spacer (Part No. 02-022-01) cutter
spindle.
10.
Select the proper cutter from Cutter Chart on pages 20-21 and place cutter on cutter spindle.
In as much as the cutter rotates in a clockwise direction as you face it, the cutter should be
placed on the spindle so the flat, sharp cutting edges lead into the pipe. Place the driving
collar spacer on the spindle and lock the spacer and cutter tightly to the spindle with the lock
nut.
