
Consider doing preventive maintenance on both high-pressure ends to reduce unplanned downtime.

Refer to the Parts lists section, which begins on page 147, for part numbers and ordering information.
Required tools, materials, and parts
13/16-inch open-ended wrench (high-pressure water fitting)
7/8-inch open-ended wrench (low-pressure water fitting)
1-inch open-ended wrench (output adapter)
1-1/6-inch open-ended wrench (high-pressure water fitting)
CAUTION
Failure to correct the cause of a leak can result in damage to the fittings.
CAUTION
Overtightening a fitting can cause it to fail. Use 2 wrenches when loosening or tightening a high-pressure
connection. Using only 1 wrench can increase bending stress to the parts and cause damage or premature
failure.
Repair or replace parts identified in the preventive maintenance schedule or if the parts show signs of
deterioration, corrosion, or damage.
Put the parts on a clean, dry, oil-free surface.
Do not use an adjustable wrench on high-pressure fittings.
