WARNING
Use 2 wrenches when loosening or tightening a high-pressure connection to prevent
causing damage or premature failure.
Do not tighten a fitting too much. The fitting can fail.
WARNING
Do not use an adjustable wrench on high-pressure fittings.
Use clean hands when changing high-pressure parts.
13/16-inch open-ended wrench or socket
(for the high-pressure water fitting)
1-inch open-ended wrench

1-1/16-inch open-ended wrench
(for the high-pressure water fitting)
Doing maintenance on the high-pressure end is easier when the plunger is moved
to that end.
