preferably at temperatures b5 … 55 °C.
4.2 Medium Term (3 Months to 6 Months)
• Remove the shaft coupling guard (if not supplied as a bare shaft machine).
• Rotate the machine shaft by hand weekly to prevent bearing indentation.
• Leave the shaft at approximately 90 degrees to the original position, using a tempor-
ary mark on the shaft to assist.
• Replace the coupling guard, taking care to align correctly and ensure that all fasteners
are replaced and fully tightened.
• Where shaft seal is gland packing, loosen the packing gland plate.
