Page 10
The speed of oscillation can be adjusted using test mode or under
actual operating conditions.
Speed Adjustment Using Test Mode
To obtain an accurate speed setting, the test (garden) hose pres-
sure must be the same as the expected header pressure.
1. To verify hose pressure, install pressure gauge by completing
the following steps. (Refer to Figure 7.)
a. Using a 1/4 in. allen wrench, remove 1/4 in. pipe plug
through access hole below garden hose connection.
b. Screw a 1/4 in. nipple (5 in. long) in place of the pipe plug
so that nipple protrudes through access hole.
c. Screw coupling onto pipe nipple.
d. Screw pressure gauge into pipe coupling.
