guisher. Lay hose straight on ground to its full 50
ft. length.
Start first regular loop clockwise by placing over
the top and between side brackets
2. The second loop is a REVERSE loop.
Notice that the hose passes behind the loop on
this reverse loop.
If instructions are followed, the hose will
uncoil without kinks.
3. The next loop is a regular “hose in front”
loop. Adjust the loops so that they are ap-
proximately the same size and then attach
the hose to the shutoff valve with either the
extension wand or nozzle installed.
