SQUEEGEE ADJUSTMENTS The squeegee set-up is pre-adjusted at the factory. Adjustments may be required to get optimum performance for different floors and conditions. 1. Ensure that the scrubber is on a relatively flat surface. Turn on the main power switch and raise the scrub head assembly off the floor.
OPERATING INSTRUCTIONS 1. Filling: Fill the solution tank with the desired amount of water and add liquid cleaning solution to the proper dilution ratio. DO NOT USE powdered cleaning chemicals. Powders are unlikely to dissolve thoroughly, resulting in clogging the in-line solution filter. This can reduce or stop water flow to the brush.
MAINTENANCE OF MACHINE VACUUM MOTOR Motor brushes can be replaced with Brush Set, Part No. 741008. Brushes should be replaced only once. More than once brush replacement will cause very high current consumption. This undue cur- rent consumption lowers overall machine performance and is not in the best interest of economical machine use.
TROUBLE SHOOTING 1. Inefficient scrubbing - floors are smeared in appearance. Solution: Use proper type and correct amount of detergent. Replace worn or damaged scrub attachments. Increase force on scrubbing head. 2. Squeegee streaks. Solution: Check rear squeegee rubber for imbedded objects, clean; reverse, or replace if worn or damaged.
