[Sentry Trailer – Operation, Startup, and Shutdown Procedures]
Erecting the Tower at Less than Full Height
In some instances, erecting the tower at less than full height may be adequate for communications.
NOTE:
All color-coded guy wires
WILL NOT
be attached to the corresponding color-coded guy ears when
using this method.
1. Attach the blue color-coded ends of the guy wires to the corresponding blue color-coded guy
ears at the top of the bottom section of the tower. Attach the yellow color-coded ends of the
guy wires to the red color-coded guy ears at the top of the top section of the tower, using the
screw pin shackle (see Fig. 6). Be sure to tighten the screw pin shackle with a wrench. Lay the
appropriate sets of three each guy wires in the general direction to which they will be anchored.
(DO NOT attach guy wires to the middle section of the tower).
2. Continue with directions “Erecting the Tower at Full Height” with one exception; stop raising the
tower when the top guy wires become taut. Do not overextend the tower.
Lowering the Tower
1. Slacken all guy wires except the lowest set.
a. Crank the tower up slightly to allow the safety stop to swing out of the way. The safety
stop is controlled by an orange cord attached to one leg of the tower.
b. After the tower has been cranked up slightly, pull the orange cord until the safety stop
clears the rung above it.
c. Start lowering the tower while keeping tension on the orange cord. The safety stop
must be kept out of the way for the complete lowering of the tower.
2. After the tower has been lowered to the retracted position, be sure to reattach the “Red Safety
Strap” around the inner section(s).
3. Remove guy wires from anchors while still in vertical position.
4. Remove the nut from the latch bolt on tower lockdown bar.
a. Be sure to retighten the nut with a wrench so that it will not vibrate loose while
transporting.
b. Push the tower away from the trailer while playing out the cable from the winch.
NOTE:
Sufficient load must be applied to the cable to overcome internal resistance and operate
brake properly. NEVER CONTINUE TURNING THE HANDLE COUNTERCLOCKWISE IF THE CABLE
DOES NOT KEEP MOVING OUT. This will disengage the brake mechanism and create an unsafe or
hazardous condition.
MINIMUM OPERATING LOAD REQUIREMENTS - Model 5351 - 75 lbs.
Failure to read and apply the instructions and warnings contained in this manual can result in
sudden failure of equipment, property damage and serious injury.
5. Lower the tower to the horizontal position and secure the tower with the hold down cable.
