7.7 Scraper Bars
Scraper bars (a) are provided on all four drums to prevent dirt from building up on
the drum surfaces. These scrapers should be inspected and adjusted as required
to remove as much dirt from the drums as possible.
To adjust a scraper:
Loosen the three screws holding each scraper to the drum casting. Position the
scraper 3–6 mm (1/8–1/4 in.) from the drum. Tighten screws and run machine to
check that the scraper does not rub against the drum surface.
7.8 Shock Mounts
Inspect the drum shock mounts (a) every 300 hours for cracking, splitting or
tearing. Replace shock mounts as needed.
NOTICE: The shock mounts isolate the upper part of the machine from the heavy
vibrations produced in the drums. Operating the machine with damaged shock
mounts for an extended period of time may eventually damage other machine
parts.
