Caution: The Boom and Mast when assembled must pivot easily.
NOTE: Once the shoulder bolt, and nut tightened completely, then the boom assembly will pivot
easily if the mounting hardware is aligned properly. To check for correct alignment of
the hardware, use the Allen key, and turn the shoulder bolt by hand. The shoulder bolt
should rotate without a lot of force being applied. If excessive force is required to rotate,
then the bolt is not aligned properly. Disassemble and repeat the assembly procedure
until the proper alignment is achieved.
NOTE: Be sure that the bolt is completely through the holes of the mast assembly mounting
bracket and boom assembly, and they are not riding on the shoulder of the bolt.

Note- To check for tightness of nut and bolt:
1. Raise the boom assembly.

Push the control handle away from the pump
assembly.
3.
If the boom assembly pivots easily, then the
nut and bolt are not too tight.
4.
If the boom assembly does not pivot easily or
does not pivot at all, then the nut and bolt are
not aligned properly.
