FOR CLEANING

M90 HANDGUNS

When cleaning the M90 handgun, a suitable sol-
vent for cleaning depends on the part(s) of the
gun to be cleaned and the material that needs to
be removed. ITW Ransburg recommends that
all exterior cleaning be done with nonpolar sol-
vents to prevent a conductive residue on critical
components. We also understand that some of
these solvents do not always meet the cleaning
needs of some materials. If conductive polar
solvents are used to clean the gun compo-
nents, all residues must be removed using a
nonconductive nonpolar solvent (i.e. high flash
naphtha). If there are any questions as to what
solvents are best for cleaning, contact your lo-
cal ITW Ransburg distributor and/or your paint
supplier.

The M90 handgun, air hoses, fluid hoses, and
low voltage/high voltage cable assemblies
should not be submerged or soaked in solvent.
However, the outer surface of these items can
be wiped with a suitable solvent. When the gun
is disassembled into individual components,
some of these items may be soaked in a suit-
able cleaning solvent. The items that cannot be
soaked are noted throughout this manual. All o-
ring and electrical components cannot be
cleaned or soaked in any solvents.

ENSURE

ENSURE the power is OFF

OFF and the

system is grounded before using solvent to

ANY equipment.

When using cleaning solvent, standard

health and safety precautions should apply.

Cleaning of the exterior surfaces of the

handgun should be done with nonpolar
solvents. If cleaning requires the use of
polar solvents, the handgun should be wiped
down with nonpolar solvent prior to going
back into use.

ROUTINE SCHEDULE

Follow these maintenance steps to extend the
life of the gun and ensure efficient operation.

Several T

Several Times Daily

imes Daily

• Turn the control unit power OFF!

• Set the trigger stop lever and inspect the air

cap for paint accumulation. Clean as fre-
quently as necessary with a soft bristled
brush and a suitable solvent.

• Clean all insulating surfaces in the system.

Remove paint accumulation from the exterior
of the gun and low voltage or high voltage
cable with a solvent dampened cloth.

Daily (or at start of each shift)

• Verify that ALL solvent safety containers are

grounded!

• Check within 20 feet of the point of operation

(of the gun) and remove or ground ALL loose
or ungrounded objects.

• Inspect workholders for accumulated coating

materials (and remove such accumulations).

• Check that atomizer assembly is clean and

undamaged.

• Check the gun electrode for damage.

• Clean the fluid filter, if necessary.

• Turn the control unit power ON. Its green pilot

should light or Aviator will be audible.

• Run a voltage output test.

NEVER

NEVER soak or submerge the electri-

cal components of the gun, i.e., cascade
barrel assembly, hook/transformer assem-
bly or cable assembly. Damage and failure
may occur.
