[Sentry Trailer – Operation, Startup, and Shutdown Procedures]
a. Tighten the nut(s) with wrenches supplied in tool kit TM-TK, which is stored in the #664
or #684 storage box.
b. Drive all three “Duckbill Ground Anchors” into the ground as described in the attached
instructions, AT-418-1.
4. Take the loose end of the three lowest guy wires and attach them to the ground anchors.
Tighten only the lowest set of guy wires. The turnbuckles should be adjusted to the fully
extended position for maximum adjustment.
a. Recheck the bubble levels to be sure the trailer is still level.
b. Also, use the 4-foot level to further check to see that the tower is as level and plumb as
possible. If tower is not level, readjust the jacks on the trailer to re-level trailer.

IMPORTANT:
Undo the Red Safety strap from the bottom of the tower and remove it from the
inner sections. It is necessary for this strap to be removed. The power winch raising the tower
can damage the tower if this strap is not removed. Please note that this strap is used to keep the
tower from telescoping out on its own when in the transport mode. Additionally, you should pull
the orange safety stop release cord to ensure the safety stop releases properly before raising
the tower.
CAUTION!
Do not attempt to raise tower in winds over 10 mph. Even in winds between calm
and 10 mph there
MUST BE
a person at
each
of the guy wires to ensure that the wires are kept
taut.
6. Raise the tower to the desired height. The safety stop engages at a rung approximately every 20
inches.
Remember that the electric winch is capable of damaging the tower, so be alert to any unusual
noises or signs that may indicate that you are doing damage to the tower. Do not try to
overextend the tower.
The tower is fully extended when the black and orange tape bands on the vertical legs of the
outer section are aligned with the bands on the inner section. When at maximum height, the
rung marked with orange reflective tape is just above the safety stop mechanism, allowing the
safety stop to rotate under this rung. The safety stop is located at the top of the lowest section.
Allow the tower to lower until the inner section rung, marked with orange reflective tape, rests
on the safety stop. Winch cable will slacken when this occurs. Serious damage will occur if
overextended!
7. Snug the remaining guy wires by starting at the lowest set. Be careful in tightening the wire and
check to be sure the tower remains aligned and level. The lowest set of guy wires can be
tightened securely; the remaining sets should only be snugged loosely.
THE TOWER IS NOW READY FOR USE.
