[Sentry Trailer – Operation, Startup, and Shutdown Procedures]
Getting Ready to Transport
1. After hooking up the trailer to the tow vehicle, fully retract the front tongue jack and lock it into
the travel position (see Fig. 1A or 1B).
2. Attach the hooks on the safety chains to the tow vehicle frame. Be sure to cross the chains
under the coupler and leave enough slack for turning (see Fig.2).
3. Hook up the trailer lights by plugging the connector into the receptacle on the tow vehicle.
Check all lights (Brake, Stop, and Running) to see that they are functioning properly.
If using electric brakes, check to see that they are properly connected and that the brake
controller is in proper working order.
4. Next, hook up the small wire cable that operates the breakaway brake control (see Fig. 3).
Positioning the Trailer/Tower
1. Position the unit in a place that will allow the following radius around the tower:70 foot radius
for the T-100H & T-100UGH towers; 60 foot radius for T-85UGH tower; 55 foot radius for the T-
75H tower; and a 40 foot radius for the T-50H tower.
2. Mark the location (120 degrees apart) of each anchor point (see Fig. 4). Refer to the enclosed
appropriate guy wire drawing specifications for your specific model.
