Hurrican High Speed Brushes. Made to the highest standard to fit our Glare Hurricane Variable High Speed Buffers. Comes packaged (2) sets of brushes totaling 4 brushes to a package. We suggest you change brushes with constent use of the Hurrican Hige Speed Buffer every two months to maintain and prevent damage to the armature. Remember when the brushes get low they will start to arc and cause damage to your machine. *Do not let this happen. Easily prevented by unsrewing the cap on the outside of the Glare Hurricane Buffer and check the length of the brush. Once the brushes are about one 1/4 inch from the bottom of the spring it is time to change them. Easily and quickly done in less than 5 min from check to finish. Get spare bushes. We suggest keep at least four or more brush sets on hand. Your beautiful Glare Hurricane Vairable Speed Buffer Derserves it!
