Model 468: Operation and Maintenance

After the skid and cutter blade have been attached to the unit, attach the high pressure hose and the placement unit. Next, lower the root cutter into the pipe or the manhole and position it with cutter blade facing in the direction of travel. (If possible, cutting should always be done against the flow to allow debris to be carried back to the working manhole.) Start jetter engine and turn on water pressure momentarily to allow root cutter to enter the line several feet. Then, turn off pressure and position hose guide/guard (tiger tail) at pipe entrance. Tie the safety rope of the hose guide/guard to the jet or clamp in place, and mark the hose top of manhole entrance with white waterproof tape.
