Hose clamp - 20 ft min behind apparatus, 5 ft from coupling, clamp slowly

Question 14

Loads

Answer 14

Flat - easy, vibration doesn’t damage, sharp bends wear on hose. Start 12-18 inches from the end for couplings.. Dutchman
Accordion load - requires only 2-3 (4 works best) and easy to grab just a few sections
Horseshoe load - fewer sharp bends than the other two. Easy to take too much hose and hard to grab some lengths for a shoulder carry. LDH doesn’t work (gets tangled)
