Greenheck ERM 36 & 52 (456785) - Manual (Page 4)

Drive Belt
Inspect the drive belt. Make sure the belt rides
smoothly through the pulley and over the rim.
Air Seals
Check that the air seals located around the outside of
the wheel and across the center (both sides of wheel)
are secure and in good condition. Air seal clearance
is determined by placing a sheet of paper, to act as
a feeler gauge, against the wheel face. To access
seals, remove cassette access panel. To adjust their
seals, loosen all eight seal retaining screws. These
screws are located on the bearing support that spans
the length of the cassette through the wheel center.
Tighten the screws so the air seals tug slightly on the
sheet of paper.
Replace cassette into ERM cabinet, plug in wheel
drive, replace access door and apply power. Confirm
that the wheel rotates freely at about 50-60 rpm.
