Ê The Danger From a Rotating Cylinder
A tremendous amount of potential energy is stored in the rotating cylinder of any washer-extractor
(even at slow speed). Washer-extractors are equipped with a door interlock designed to prevent the door
from being opened if the cylinder is turning and to prevent the machine from starting unless the door is
closed and locked.
Some smaller machines permit the door to be opened only during the first few minutes of the formula
and only while the machine is rotating in wash speed. If the door is opened, the drain valve opens immedi-
ately, the formula terminates, and (provided the machine still has electric power) on most, a brake is imme-
diately applied.
All larger washer-extractors are equipped with a spring-applied, air-released brake which remains ap-
plied as long as the door is open and stops the cylinder whenever any of the following occurs: 1) the extract
cycle ends, 2) the extract is manually terminated, or 3) the machine loses electric power.
Most machines permit the cylinder to be inched or jogged at slow speed, but only with two hands.
ENTANGLE HAZARD—The linen inside or hanging partially outside the
turning cylinder can suddenly wrap around your hand, arm, or body and
twist off/sever it.
☞
DO NOT put any part of your body in the machine while it is moving.
☞
DO NOT operate the machine with the door open.
☞
DO NOT open the door while the cylinder is turning.
☞
DO NOT touch the linen or load/unload machine while the cylinder is turning.
☞
DO NOT open the door if there is water in the machine. You can be scalded by hot water.
☞
DO NOT tamper with or disable any safety device on the machine.
☞
DO NOT operate the machine with a malfunctioning door interlock mechanism.
☞
DO NOT operate the machine with malfunctioning two hand inching, if so equipped.
EXPLOSION HAZARD—A damaged cylinder can rip apart during extract,
throwing out metal fragments at high speed like an exploding grenade,
killing/injuring personnel and damaging property.
☞
DO NOT operate machine with any evidence of cylinder damage.
Ê The Danger From Processing With Flammable Materials
Washer-extractors are manufactured specifically for use with water, not with any type solvent nor with
any other material that might be flammable. They are not suitable for any type of solvent cleaning process.
EXPLOSION AND FIRE HAZARDS—Goods containing flammable materi-
als or fumes can explode or ignite spontaneously, killing/injuring person-
nel and damaging property.
☞
NEVER process goods containing any significant quantity of flammable chemical.
