Figure 6: Screw Placement
6. The mast brackets should be installed according to the orientation shown in previous
illustrations. Using the #2 Phillips screwdriver provided, tighten the screws through
the large and small mast brackets through the mast and into the nut plate that is
already fitted with inserts.
7. Engage the brakes on the swivel casters of the platform so that they will not roll.
Carefully raise the mast to a vertical position and insert the lock pin provided to hold it
in place.
Do not attempt the next portion of the assembly with less than two people.
Care should be taken to keep the carrier from contacting the platform during
this procedure so that it cannot damage the platform.
8. Leaving approximately one turn of rope on the winch drum, pull the hoisting rope tight
through the clamp block on the brake. Once the clamp is fully tightened onto the
rope, tie a loose half-knot on the mast side of the clamp to make sure the rope does
not slip back through the clamp. Once this is accomplished, wind the excess rope
around the clamp portion of the brake so that the brake still functions correctly and
the rope does not interfere with the carrier working properly.
9. Attach the free end of the guy lines to anchors located on the ground plane or within
the chamber.
