7. Remove the bolt and locknut from the top of the mounting bracket of the mast
assembly.
8. Align the holes of the boom assembly and mast assembly mounting bracket. Insert the
bolt completely through the holes of the mast assembly mounting bracket and the
boom assembly.
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.
The boom and mast, when assembled, MUST pivot easily.
9. Tighten the bolt and nut using the Allen wrench provided and an adjustable wrench.
NOTE: The nut and bolt can be tightened completely and the boom assembly will pivot easily if the
mounting hardware is aligned properly when the boom assembly is secured to the mast. To check
for correct alignment of the hardware, use the Allen wrench provided and turn the bolt by hand (it
should rotate without a lot of force being applied). If excessive force is necessary, the bolt is NOT
aligned properly. Disassemble and repeat assembly procedures until proper alignment is obtained.
10. To check for tightness of nut and bolt:
A. Raise the boom assembly.
B. Push the control handle away from the pump assembly.
C. If the boom assembly pivots easily, then the nut and bolt are not too tight.
D. If the boom assembly does not pivot easily or does not pivot at all, then the nut and
bolt are not aligned properly.
Boom Assembly
NOTE: Mast assembly mounting
bracket, boom assembly, bolt and
locknut MUST all be flush against
each other
