How to Do a Test of the Mechanical Brake
WARNING 32 : Crush and sever hazards—The goods in the cylinder can cause it to
turn when the machine is stopped.
• Do not let the machine operate with a defective mechanical brake.
The disk or band brake holds the cylinder while the operator puts goods in, or removes goods
from the machine. Although the mechanical brake does not usually stop the cylinder during
operation (Note 2 tells more), it can do so if an an unusual condition occurs. Examples are
when electrical power is removed and when a stop switch is pushed. To make sure the machine
operates safely, do this test at the intervals given in the maintenance schedule:
1. If the machine contains goods, remove them.
2. Start a wash formula. Move forward in the sequence to a drain (see
the test when the cylinder turns at drain speed. Wash speed is too slow. Extract speed will
cause deterioration of the brake components that is not necessary.
3. Look at the cylinder through the door glass or site glass.
4. Push the Emergency Stop
appropriate for the type of machine:
Divided cylinder and Staph Guard
Open cylinder—10 seconds
Note 1: On most machines, there is no manual output for drain speed. If your machine has a drain speed
output in Manual Mode, use it instead of a formula.
If the cylinder does not stop in the given time, repairs are necessary. Speak to your dealer or
Milnor. This is not routine maintenance.
