Correct maintenance will help to ensure the life and dependable
operation of the water oscillating monitor. The following proce-
dures should be conducted every six months or more frequently if
desired.
1. Perform monitor testing procedures as indicated on Page 6.
2. Clean the filter element by completing the following steps.
(See Figure 5.)
a. Unscrew 1 1/4 in. hex plug on right side of oscillating mech-
anism enclosure.
b. Remove gasket and bronze filter element from opening.
c. Clean any foreign particles from filter element using pres-
surized air or water.
d. Reinstall filter element and gasket. Replace hex plug.

3. Check that flange bolts are tight and monitor supports are
secure.
4. Manually rotate monitor to line up grease fittings with access
holes in left side of enclosure. (See Figure 4.) Lubricate spar-
ingly with monolithium grease.
5. Lubricate monitor base couplings and elevation couplings with
monolithium grease. (To grease the WOM-3 monitor base
coupling, the monitor must be rotated approximately 90° to
the right so that grease fitting can be reached through access
hole at side of enclosure.) See Figures 1, 2, and 4 for grease
fitting locations.
6. Remove cover from oscillating mechanism enclosure.
7. If chain requires tightening, complete the following steps and
refer to Figure 6.
a. Unscrew bolt that secures clevis assembly to enclosure
chassis.
b. Remove one of the washers between clevis assembly and
chassis.
c. Place the washer (that was removed) between the bolt
head and the chassis assembly to maintain clearance
between end of bolt and chain sprocket.
d. Reattach clevis assembly to chassis making certain
washers are in place.
e. Recheck for clearance between end of bolt and chain
sprocket.
