• Never use a flammable or combustible fluid in this

unit. Use only nonflammable, non-combustible,
water-based, low foaming cleaning compounds in this
machine. For best results, Graymills’ recommends
using Aquatene 330, Super Aquatene 360, or
Aquatene 571.

• Do NOT contaminate cleaning fluid with any

flammable or combustible material such as gasoline,
alcohol, mineral spirits, etc. Drain parts to be cleaned
of any flammable material or combustible material
before placing inside cleaning tank. Even small
quantities can create a dangerous fire hazard.

• Never work with equipment you feel may be unsafe.

Contact your supervisor immediately if you feel a
piece of equipment is in an unsafe condition.

• Cleaning solutions may be irritating to skin and eyes.

Always wear gloves, apron and safety glasses when
using. If splashed in eyes, flush thoroughly with water

and follow directions on cleaning solution MSDS.

• Install machine in a well ventilated area to avoid possible
buildup of cleaning solution fumes.

• Cleaning fluids should have a pH under 12.5.

• This is a heated system. Always use caution when first

putting hand into cleaning solution. Higher temperatures
can cause burns to skin and will damage pump. This
unit's thermostat has a maximum temperature of 120ºF.
Do NOT attempt to exceed thermostat setting.

• Should cleaning solution become uncomfortably hot

despite adjusting thermostat to a lower temperature
and/or the heat light is on continuously, unplug
machine and discontinue use. For instructions on

changing the thermostat, please see the Troubleshooting
section.

• If any cleaning solutions are splashed on clothing, change
promptly and thoroughly wash any body areas which have
been in contact with solution. Apply lotion. Do NOT

permit saturated clothing to remain in contact with
skin.

• After extended use, the gas-spring used to assist in
opening and closing the lid may lose its ability to keep the
lid open. At the first sign of this, replace the gas-spring
immediately. (See Spare Parts List)

• Automatic Safety Cover. Since certain soils may be
combustible, e.g., oils, greases. This unit is equipped with
a fusible safety link cover mechanism designed to support
the open cover at a slightly forward angle. In the event of
a fire, the fusible link will melt at 165ºF permitting the
cover to slam shut, cutting off oxygen supply to the fire.
(See Spare Parts List)

• Failure to keep proper liquid level will result in
burning out the pump and heater coil, creating a
potential fire hazard. To help prevent this, this unit is

equipped with a low liquid level device which will shut off
the pump and heater. If solution stops circulating and the
red “FAULT” light becomes illuminated, immediately turn
off and unplug unit. For instructions on filling the reservoir,
please see the Troubleshooting section.

• Do not leave the unit unattended with parts in the tank
which would prevent the cover from closing
completely in the event of a fire. Keep cover closed
when unit is not in use. If the fusible link breaks, do
not operate the unit until a replacement link is
installed. (See Spare Parts List)

• Turn heater and pump off when unit is to be idle for
extended periods (overnight and weekends).

• Maximum shelf capacity 150 pounds.
