sinking. The stability of the stand is of prime importance for
secure operation. For outdoor use on a soft surface, 3/4”
plywood pads under each foot is recommended

leg to level the stand. Once the stand is leveled, release the
spring loaded safety pin into the positioning hole and tighten the

the top masts only. The top mast must be raise first, followed by
the second mast in sequence.
3): Pull the safety spring loaded pin (I) to unlock the top mast.
4): Turn the winch crank (H) clockwise to raise the top mast. When
the desired height has been reached, release the safety spring
loaded pin into the positioning hole on the mast.
5): Tighten the tension knob (G) to secure the mast and to avoid
any lateral movement and further lifting.
6): Repeat steps 1-5 with on the 2nd mast. Loosen the tension knob
(G2) and release the safety spring loaded pin (I-2)
7) Once the desired working height has been obtained and all
spring loaded pins have been locked and the tension knobs
have been tighten, turn the winch crank handle(H) a 1/4 turn
counter clockwise to release tension from the cable.
IMPORTANT
1) All equipment that is being raised by the cranks should be
secure with Global Truss TUV rated clamps and safety cables
prior to raising the mast to the desired working height.
2) One operator per stand is required when using the stands in
pairs to lift trussing.
3) Keep hands and fingers clear of the steel cable and mast
when lifting or lowering the mast.
