1. Do not side load from plumb more than 15 degrees. That is gingerly provide force and energy pulling within 15 degrees. Plumb is 12 o'clock to 6 o'clock. 15 degrees is 7 to 8 and 5 to 4 on a clock face.

2. At 30% and 60% the boom will handle the load greater than the rating on the end of the boom.

3. The hose clamps are too prevent a side load slide. This is the danger zone. Always keep the majority of weight on the boom end and no more than 50% within 15 degree off plumb.
