Inspect condition of parts to be cleaned. Parts should be free of paint before
placing in the tumbler. Paint can be removed by soaking parts in a metal
container of Eastwood DEKOTE paint stripper (#10410) Qt., (#10411)
Gal., XXX Finish Stripper (#21658Z) Aerosol, (#21659ZP) Qt., or Eastwood
Powdercoat and Paint Dissolver (#12849) Qt., (#12850) Gal. Do not under any
circumstances put paint removers or solvents in the Tumbler bowl.
Parts can be degreased by soaking in a solution of Metal Wash (#10120) (See
package for directions). Or for faster degreasing, add about 1-2 teaspoons of
Metal Wash concentrate (#10120) to any wet media then add enough water
to wet the parts. Rinse cleaned parts in water and allow to dry. For best results
sort parts to be tumbled by approximate weight and condition. Tumbling similar
weight/condition parts together will yield most efficient results.
Place Tumbler on a clean, dust and grit free surface. The Tumbler rubber feet
are designed to prevent the Tumbler from “walking” during normal operation.
We recommend that the machine be placed on a solid floor, away from any
combustible materials. If machine is to be operated on a bench, it should be
blocked in to prevent any accidents. Always connect machine to a properly
grounded outlet to prevent electrical shock.
NOTE: Plating may be eroded away by wet media. To shine
plated parts with the least removal of plating use a dry media.
Refer to Producing a High Shine section and check parts
frequently to assure desired results.
NOTE: Do not overload unit. Overloading the unit may result in
motor burn-out which will void your warranty.

1)
The ratio of media to parts should be 70:30.
2)
Add no more than 35 lbs of media to the bowl or to within ¼” from the top
of the central bowl cone (whichever is less).
3)
Add no more than 15 lbs of parts to be cleaned. Parts should be about 7”.
4)
Add water and rinse additive (if required). If the media requires water, only
add enough to completely wet the media without creating standing pools
of water. Excessive water will dampen the vibratory action while too little
water will impede proper action.
5)
Plug Vibratory Tumbler into properly grounded 110 VAC outlet. Tumbler will
start vibrating as soon as it is plugged in. Observe tumbling action. Most
efficient vibratory tumbler action occurs when the media and parts are
seen to both rotate around the bowl circumference and cascade laterally
NOTE: This tumbler features a moveable counter-weight to adjust the
vibration from mild to aggressive. If the media and parts are not moving as
they should check to make sure the maximum 50 lbs total weight hasn’t
been exceeded. Reduce weight if needed. To further adjust tumbler action:
Remove plug. Remove central bowl retainer nut and remove bowl. Place
base unit on side and unbolt the bottom coverplate. Loosen the thumb
nut on the counterweight by turning the screw CLOCKWISE. Moving the
weight out increases the vibration, moving the weight in so it completely
overlaps the fixed weight produces the mildest vibration action. Move
weight to desired position and hand tighten by turning the thumbscrew
COUNTER-CLOCKWISE. Reinstall base cover plate and bowl. Plug in
tumbler and observe for proper media movement.
6)
Place lid over central mounting stud, install washer and hand tighten the
retaining nut.
7)
Typical processing times range from 3 to 7 hours. It is recommended to
check periodically to see if the desired finish has been achieved. Actual
time to achieve this appearance may vary from one hour to several hours
depending on condition of media and degree of rust on parts to be
cleaned and strength of the agitation.
8)
For many parts no further surface conditioning is needed. If this is the
case, make sure Tumbler is unplugged.
9)
Remove lid and tumbler bowl assembly. Tip tumbler bowl, with lid slightly
ajar, to drain out wastewater in appropriate drain. In most cases water can
be poured down any convenient drain. Once water is drained, pour entire
contents of tumbler bowl onto a paper towel or cloth.
10) Use a magnet to remove steel parts from media or manually sort through
to pick out cleaned parts. Dry parts with a hair dryer or heat lamp. Allow
media to air dry and return to container of unused media for future use.
NOTE: The wet media has abrasive throughout its cross section.
The smaller worn particles of media will help clean tighter
radius areas.
NOTE: Do not overload unit. Overloading the unit may result in
motor burn-out which will void your warranty.
Put hardware back into service or paint/plate as desired to improve corrosion
resistance.
