CREAMER’S CORNER
Diagnostic: Over the phone?
In an ever changing world, the once simple sweeper or scrubber was just that, a
sweeper or a scrubber. In the year 1985 all that changed. Power Boss introduced the first true
sweeper/scrubber.
Today, even though you can still buy just a sweeper or a scrubber, combinations are
becoming more prevalent in the marketplace. Let’s list what is available today:
1. Sweeper
2. Scrubber
3. Commercial Sweeper/Scrubber
4. Intermediate Sweeper/Scrubber
5. Total Sweeper/Scrubber
6. Scrubber with Pre-Sweep
With all of this to digest, it’s easy to understand why mechanics in other fields, let’s say forklifts, has
great difficulty repairing sweeper/scrubbers. Let’s face it, there is a lot to comprehend and unless you’re
trained in this field, you can do your customer a great disservice.
Which leads me to the topic of today; Diagnostic: over the telephone. In almost thirty years, I have seen
or heard about everything. In all of that time, I can tell you the number one problem, above all, is not having
any parts or service manuals to refer to. I can’t imagine working on a unit (let’s say an American Lincoln
Model ATS 46/53) without a manual. This machine is a hydraulic and an electrical nightmare. It’s hard
enough to figure out problems WITH the manuals.
There are, however, problems that are basic and consistent with what the machine performs. For
example: #1 The sweeper is leaving debris on the floor going around corners:
