Do Not grab the pulley - you can lose fingers that way. Gloves,
Goggles, and anchor one end of a hemp or coir natural fiber rope, and
loop it around the pulley like you're using it as a windlass drum. You
can adjust the drag that way.
Oh, and have a bucket of water handy to put out the rope if you test
it too hard.
a squirt bottle like a window cleaning bottle works fine for those
small somewhat expected rope issues. However...do NOT use one that
contains WD-40! The expected becomes very much unexpected if that is
used. Truely.
Don't use WD-40 to clean the brushhes/comutator on an el-cheapo
weed-wacker while it is running either! DAMHIKT
Isopropyl Alcohol would probably work better butbe satisfied to turn
it by hand and let it thoroughly dry before applying power.
