Dis, which model whipper is this?

I used to use a Stihl whipper when working on the highways. These things would be running 12 hours straight in 30 degree weather. The only time they were turned off was to restring the spool. I had to restring it about 6 times a day. We went through a lot. I banged that thing into the ground so many times to get the string to come out. Here's a few tips.

Don't let the string get too short before letting some more out. The smaller amount of string results in a faster speed required to overcome the loss of centrifugal force (which is required). If it's too short, no force will get the string to feed and you'll need to do it by hand.

What I did was I pounded the "button" on a hard rock or surface while spinning it. A tap was all I needed usually to feed more string out. I did this periodically, about when the string was at half length. Also, when filling with string again, make sure you wrap it on the spool carefully, avoiding criss crossing lines and possible entanglements.

As for those plastic blades someone mentioned above... those lasted 30 seconds on my whipper until I threw them out. Absolute crap for cutting grass, they took forever. Good for hard stalks like cattails though. Buy a good quality line, and you'll be ok.
