33 Feet Telescoping Fiberglass Mast

Instruction Sheet

Thank you for purchasing the MFJ-1910 33 Feet Telescoping Fiberglass Mast. Please read these instructions carefully before use.

Caution!

Improper extending and collapsing of the MFJ-1910 mast can cause the sections to bind. DO NOT collapse the top section (thinnest section) first. If the top section is collapsed first, it can get lodged between the larger sections. This will cause the sections to bind and you will not be able to fully collapse the mast. You may not be able to fully extend the mast the next time you use it. To avoid this, follow the directions below.

When extending the mast, be sure the thin, top section with the metal loop is extended first. After extending the top section, twist the section at the joint slightly for a tighter fit. Then proceed to the next section. Follow this procedure until the last section is tightly in place.

When collapsing the mast, begin with the bottom section. Twist the sections at the joint to loosen and gently lower into the bottom section. Then proceed to the next section. The last section lowered into the base should be the thin, top section with the metal loop.

If sections of the MFJ-1910 mast become wedged together unscrew the cap on the bottom of the mast. All sections should be removed from the bottom until the sections wedged together can be seen. Remove the top section from the sections stuck together. Replace the sections (largest diameter first). Screw the bottom cap back on after replacing the last section.
