As Needed:
Check that the interior of the monitor inlet is clean. Flush out any dirt with clean
water. To assure ease of left/right rotation, periodically apply a light coating of
general-purpose petroleum grease to the U-Cup seal within the monitor inlet. Do
not remove the seal for lubrication.
Grease the worm gear as needed with general-purpose petroleum grease. Rotate
the manual override to raise the discharge to its highest elevation, apply grease to
the fitting located on the lower front of the unit. Fill it until grease appears at the
discharge elbow joint. Lower the discharge to the electronic stop limit and repeat
the grease procedure. Lower the discharge to its lowest position, and repeat the
grease procedure again. Raise the discharge until the electronic stop is reset.
Wipe off the excess grease. Clean the monitor with soap and water only. DO
NOT use any type of solvent, thinner, or similar product with this unit.
Replace the labels if they become illegible, lost, painted over, or removed.

Bases
After Each Use:
Clean any dirt from the unit with mild soap and fresh water. DO NOT use any
type of solvent, thinner, or similar product with this unit. No lubricants should be
used on the portable bases. The aluminum parts are hard coated and Teflon
impregnated and need no lubrication.
Inspect the ring gear, looking for damaged or dirty teeth. Clean the teeth if
necessary.
Inspect the spring loaded ground spikes for damage and proper function. The
spike assembly parts should move in and out freely. Inspect the ground spikes.
The carbide tips should come to a sharp point. Replace the ground spike
assembly if the carbide tips are damaged. Replace the ground spike assembly by
removing the ground spike retainer from the leg. Turn the retainer counter-
clockwise with the correct size socket or wrench, and remove the spike assembly
and coil spring. Clean the leg socket. Place a small amount of Loctite #242 on
the male thread of the retainer before installation. Install the spring, new spike
assembly, and retainer. Tighten the retainer firmly.
Inspect each of the folding legs for correct operation of the lock pins and smooth
operation on their pivot screws. Check the leg lock pins by sliding them back and
forth in their bores using the yellow-capped pins on both sides of the leg near the
pivot point. The lock pins should slide smoothly in the leg bore and the cone-
shaped end should fit snugly into the tapered hole in the leg bracket. Retract the
lock pin and rotate the leg back and forth on the pivot screw. The leg should
rotate freely. If needed, flush the leg assembly with water while cycling the lock
pin and/or leg through its full range of motion until smooth operation is achieved.
Inspect the safety strap and snap hooks. Make sure that the spring-loaded closure
on the snap hooks pivots freely and returns to the locked position.
