Cleaning
NOTE: Dorner recommends cleaning all the “food
zones” prior to placing conveyor into service. Insure
adequate access is provided for cleaning and
servicing equipment so that the required level of
hygiene can be maintained.
IMPORTANT: Do not use belt cleaners that contain
alcohol, acetone, Methyl Ethyl Ketone (MEK) or other
harsh chemicals.
Use Dorner Belt Cleaner (part # 625619). Mild soap and
water may also be used. Do not soak the belt.
For /05 woven polyester and /06 black anti-static belts,
use a bristled brush to improve cleaning.

The weight of the gearmotor is all on one end of the
conveyor which could cause it to tip off the stands
when the mounting clamp plates are loosened. Be
sure to provide support (AT of Figures 21 and 22)

Exposed moving parts can
cause severe injury.

NOTE: Do not exceed a torque of 25 in-lb (2.8 Nm)
for 2¨ to 12¨ (44 mm to 305 mm) wide conveyors or 40
in-lb (4.5 Nm) for an 18¨ (457 mm) wide conveyor on
tensioning screw (AO). Over-tensioning the
conveyor belt could cause excessive pulley bearing
load and early failure.
2a.For an existing belt, extend idler spindle assembly
(AN) by turning M6 hex head screw (AO) clockwise
to sufficiently tension belt to handle conveyor load.
