3. Clean squeegee blades with a cloth. Replace
blades when they become worn.
4. Check bag for fullness, empty bag at 3/4 full.
5. Wipe machine housing with a nonabrasive,
nonsolvent cleaner.
6. Check cords and cord grips for damage. If worn or
damaged, replace immediately. Coil cord neatly.
ATTENTION: Always have float shut- -off screen in
place before operating. During wet operation, the
shut- -off float protects the vacuum motor from
water. During dry vacuuming, the float screen can
provide limited protection for a faulty filter bag.
7. Inspect vacuum hose regularly for holes, loose
cuff or clogged debris.
