OPERATION
A.
FLOWING WATER
Slowly charge the hose line with water. Build pressure until the gauge reads the rated tip pressure. A minimum
operating pressure of 70 psi is required. NOTE: The unit will discharge some water from the oscillation
mechanism during use.
B.
CHANGING SWEEP RANGE
1.
Before adjusting the sweep range, stop the oscillation by depressing the oscillation ON/OFF knob.
2.
Move the travel control knobs to desired position. The left knob controls the right travel and the right
knob controls the left travel.
3.
Restart oscillation by gently pulling oscillation ON/OFF knob out.
C.
TO STOP UNIT IN PLACE AND USE AS A NON-OSCILLATING MONITOR
1.
Depress the oscillation ON/OFF knob when the nozzle reaches desired position.
2.
If placing the unit in the vertical position, STOP the oscillating motion by pushing in on the oscillation
ON/OFF knob and adjusting the elevation.
D.
TO OSCILLATE UP AND DOWN
1.
Make sure no water is flowing to the unit.
2.
Depress the oscillation ON/OFF knob.
3.
Loosen the elevation knob.
4.
Point the outlet straight up.
5.
Rotate the outlet 90˚.
6.
Lock the elevation knob.
7.
Push the nozzle to either end of travel.
8.
Pull the oscillation ON/OFF knob.
9.
Get all personnel away from unit.
10.
Slowly charge the unit until the pressure matches the nozzle rating.
E.
AFTER SHUTDOWN
1.
Remove hose.
2.
Tilt the unit and drain as much water as possible from the body of the unit.
3.
Move the discharge outlet back and forth by hand to drain as much additional water as possible
from the unit. This minimizes the possibility of corrosion and freezing.
4.
If the unit was used for foam application, with salt water or with brackish or dirty water, be sure
to operate with clean water for at least 5 minutes after shut down.
5.
A carry handle is provided for manual transport of the monitor.

ROUTINE MAINTENANCE PROCEDURES
3 Month Intervals
1.
Piston Rod Lubrication - (see figure 2) Lightly grease each end of the piston rod with Parker-O-Lube or
equivalent barium grease if it becomes dry or every three (3) months. When greased properly, the rod
will have an evenly dispersed layer of grease covering the exposed portion of the rod. Distribute grease
evenly by pushing outlet back and forth.
2.
Ground Spike Inspection - If the flat on the pointed end of any spike exceeds 1/16" (0.016mm) diameter,
the spike must be sharpened or replaced. The spike is the sharp end of the ground caulk which comes
in contact with the ground. To order replacement spikes, contact your local Akron Brass Distributor.
3.
Safety Straps - Examine strap for wear and make sure both hooks easily snap into the front leg clips.
If straps need replacement, contact your local Akron Brass Distributor.
6 Month Intervals
4.
Every six months, grease the threaded portion of the elevation brake knob with Parker-O-Lube or
equivalent barium grease.
A Field Service Repair kit is available. Contact you local Akron Distributor and ask for Field Service kit Style 9191.
WARNING:
Maintenance should not be performed while flowing water. Disconnect from water supply prior to
maintenance.
G.
TROUBLE-SHOOTING
If the unit fails to operate properly or stops:
1.
Check oscillation ON/OFF knob. Make sure knob is pulled out.
2.
Check operating pressure. Make certain an operating pressure of at least 70 PSI
(438 kpa, 4.83 bar) is maintained.
3.
Check travel control knobs. Do not place both travel control knobs on the center position at the same
time. If you want to stop the oscillation, depress the oscillation ON/OFF knob as previously described in
Section
B.
4.
If the unit does stop during operation, lower the line pressure to zero, push the discharge against the left
stop and repressurize.
