3.3 SYSTEM USE:
Step 1. After the Counterweight Base has been assembled and leveled at the job site by following the
above procedure, the available space around the set up area will determine the extension distance
required for the Crossmember Extension. The correct amount of weight must then be placed on the
Counterweight Base. Refer to the table and illustration in Figure 5. The table provides the amount of
weight required as a counterweight, depending on the reach of the Offset Mast and the number of
holes exposed on the Crossmember Extension.
Step 2. Remove the counterweight Cover Plates (Figure 5, item 8) after unthreading and removing the
security nuts. Install (stack) the required counterweight plates onto the weight mount poles with the
weight mount poles protruding through the matching hole in each counterweight plate. If possible,
ensure all poles have an equal amount of weight.
Step 3. After the required number of weight plates have been installed, replace the Cover Plates on the
weight mount poles and tighten all four security nuts snugly.
Step 4: Recheck the assembly to make certain it is level and that each of the four feet is in firm contact with
the job site surface.
