This sander is designed to sand in hard to reach places, e.g. underneath steam radiators and deck railing. It uses 5" PSA sanding disks. It should not be used as a replacement for the floor edger, but solely for its intended purpose.
This unit runs on 120VAC and a 20' cord is included in the rental. A dedicated 15A circuit should be used. Use of additional extension cords is discouraged and may result in popping electric breaker. This is not a dustless sander. The use of eye and ear protection is recommended for all sanders.
