About this procedure
After you troubleshoot the on/off valve, it could seem like you only have to replace one or two parts
from the seal kit. However, all seal kit components have similar expected life times. If one
component failed, the others are also likely to fail very soon! We recommend that you install all
seal kit components at the same time to reduce maintenance time and machine downtime.
When working on high-pressure components, it is critical that you use backup wrenches. Excessive
torque on the cutting head can damage the wrist motors. Such damage will void your warranty.
