Safety Instructions

The system is rated to the load stated. The end user is responsible for ensuring the loads are securely fastened. Rolatube Technology does not accept liability or provide warranty for usage deviating from the enclosed instructions.

  1. Before deploying the mast please read all warnings below.
  2. Avoid contact with heavy and sharp objects, in storage do not stack anything on top of Rolatubes.
  3. Do not use the mast if there is visible damage.
  4. The end user must assess the suitability of the pegs provided for the intended deployment environment, and replace with more suitable products if necessary.
  5. Rolatube mast systems are rated for wind speeds of up to 100kph (62mph). The maximum wind rating is based on the bare mast correctly deployed and guyed. The end user or system integrator is responsible for ensuring the system is safe with the top load mounted.
Warnings
  1. Ensure the deployment site is clear of any cables or equipment that represents an electric shock hazard.
  2. Do not deploy near power lines, in thunderstorms or winds exceeding 100kph (62mph).
  3. Do not exceed the rated top load of the mast.
  4. Ensure any top load is securely fastened.
  5. Do not allow the mast to bend.
  6. Ensure the deployment site is clear of any underground hazards before using pegs.
  7. Ensure guy ropes and pegs are secure for duration of deployment.
  8. Consideration must be given to the location of any cable from the top load to avoid trip hazards.
  9. Consideration must be given when deploying in proximity to an aircraft landing site for aircraft movement.
  10. Rolatube masts are only designed to function in the vertical axis.
  11. Deploy the mast with the slot facing away from any prevailing wind.
Deployment Instructions
During mast deployment, attach the hoist rope using one of the following methods before continuing mast deployment as per the mast user guide.
1

Option A: Top Cap Clip

During the mast deployment, fit the clip to the top cap and feed the antenna hoist rope through the clip on the top cap. Secure the hoist rope to prevent it being raised with the mast.

Option B: Secondary Cuff

Fit the secondary cuff to the mast at the desired height and secure in place using the thumb screw. Attach the clip to the lanyard. Feed the hoist rope through the clip on the secondary cuff.

5

Connect Hoist Rope & Dipoles

Connect the hoist rope to the top of the resistor tube using the snap hook. Unroll the dipole antenna legs and connect to the resistor tube and balun. Ensure all four strain relief snap hooks are correctly fitted.
