Cleaning
WARNING: Blow dirt and dust out of all air vents
with clean, dry air at least once a week. To
minimize the risk of eye injury, always wear
ANSIZ87.1 approved eye protection when
performing this.
WARNING: Never use solvents or other harsh
chemicals for cleaning the non-metallic parts of
the tool. These chemicals may weaken the plastic
materials used in these parts. Use a cloth
dampened only with water and mild soap. Never
let any liquid get inside the tool; never immerse
any part of the tool into a liquid.
Repairs
WARNING: To assure product SAFETY and
RELIABILITY, repairs, maintenance and
adjustment (including brush inspection and
replacement, when applicable) should be
performed by a CRAFTSMAN authorized service
center. Always use identical replacement parts.
Storage

following:
1. Review the Maintenance section on the
proceeding pages and perform scheduled
maintenance as necessary.
2. Drain water from air tank. See To Drain Tank
under Maintenance.
WARNING: Water will condense in the air tank. If
not drained, water will corrode and weaken the
air tank causing a risk of air tank rupture.
3. Protect the electrical cord and air hose from
damage (such as being stepped on or run over).
4. Store the air compressor in a clean and dry location.
