No harm in asking shows you want to learn,first off check for rips and cuts in the curtain and put them on your check sheet to cover yourself.
Check that the curtains are tight sounds daft but loose curtains will blow about as our driving never a good look,might seem a pain in the ■■■ but before you set off tighten the curtains,pull the strap down a bit on the buckle and pull the buckle towards you minding your fingers and undo it from under the trailer at the back of the trailer there’s 2 levers pull the catch holding the 2 levers so they are free take the bottom handle and pull towards you making sure the handle locates on the gear and tightens the curtains push lever back and do the buckles up,a tighter curtain will drive better when its windy.
When you tip or unload beware as said of the pole giving you a wack bloody hurts lol,take front or back out 1 at a time then slide the other half out and put the pole back just loaded from,to do back up put pole in locate and push the top lever inwards then the bottom lever to locate leave tightening till your done.
