Hose Concentrate Sprayer
 

This will probably seem a stupid question to most of you but I'm
baffled. I've got a Hudson Hose End Liquid Concentrate sprayer. On the
top it has 12 settings ranging from Off to 6 gal. On the front label on
the left side it has the number of gallons marked all the way up to 6
gallons. On the right side it has ounce graduations up to 32 oz.

If I'm diluting 1 oz of concentrate to one gallon of water I understand
how to do this. My question is what the heck should I do with the
settings on top. My plan is to put six ounces of concentrate in and
then fill it up to the six gallon level. What the heck do I do with the
setting on top??

The exact dial settings on top a

1 tsp
1.5 tsp
2 tsp
1 tbs
4 tsp
1 oz
OFF
1.5 oz
2 oz
2.5 oz
3.0 oz
4.0 oz
6 gal

Thanks in advance for your help.
