USING THE OPTIONAL SLURRY EVACUATOR

The slurry evacuator is used to pump the slurry out of the Vapor Blast machine hopper into a 55 gallon

drum or some other suitable receptacle for disposal.

1. The slurry pump must be running to have all the abrasive in complete suspension.

2. Hold the discharge end of the 2" diameter hose supplied firmly into the disposal container.

3. Slowly open the air supply valve which feeds air to the evacuator.

4. Open the hopper drain valve.

5. Slurry will now be discharged from the hose in a pulsing action. If pulsing is too vi,olent, reduce the

air pressure.

After the used slurry has been emptied, thoroughly rinse down the inside of the cabinet, including the

window drain trough. Close the hopper drain valve and recharge with new abrasive.

MAINTENANCE

Weekly

1. Inspect counterweight cables and emergency door stop unit. Check cable clamps at each end of

cable to ensure tightness. Check general condition of cable throughout Its length. If cable is worn

or frayed, It must be replaced immediately. Inspect cable roller pulleys. Pulleys should rotate freely.

Clean emergency stop unit of all accumulated abrasive. Use a wire brush If necessary to remove

build-up. Check to be sure the unit hinges forward. This is done by sliding the door towards the

closed pOSition. Allow It to "hit bottom". When the door hits bottom, observe the emergency stop

unit. It should hinged forward in a snapping motion. If unit is functional, lightly oil hinge with spray

type penetrating 011.If unit Is frozen, clean or replace. Retest unit following above instructions.

2. Clean exhaust filter. The exhaust filter should be cleaned every time the abrasive is changed or

after 40 hours of machine operation. This cleaning involves removing the filter from the filter

housing and washing/brushing in a forceful stream of water. If filter is too clogged to be cleaned, it

must be replaced. The manual or automatic filter wash equipped with the machine helps prevent

clogging during operation. Filter removal and cleaning is stili necessary. If the machine is equipped

with optional "van type" filter, a manual or automatic rinse is not used. This filter must be cleaned

following the preceding procedure and time interval.

MAINTENANCE

3. Thoroughly rinse inside of blast cabinet every time the abrasive Is changed. Particular areas to

concentrate on are:

* Entire inside of filter housing

* Filter housing drain hose

* Window trough and drain hose

* Pump Intake strainer

NOTE:USE A SCRAPER OR WIRE BRUSH TO REMOVE EXCESSIVE ABRASIVEBUILD-UP.

4. Drain and clean settling tank. Excessive build-up in settling tank will lead to hard packing of the

settled abrasive. The settling tank IIlU§l be cleaned every week. The settled abrasive can be

scooped out of the bottom of the settling tank. An alternative is to purchase an optional pneumatic

vacuum unit.

5. Clean light window. Use a non-abrasive commercial window cleaner.

Monthly

1. Inspect blast gun nozzle(s) and air jet(s) for wear. Replace if the 1.0. Is more than 1/16" oversize.

Example: 1/2" nozzle 1.0. is .500 new; replacM when 1.0. exceeds .562.

When replacing the air jet, refer to blast gun assembly drawing for correct positioning In the gun. If

the air jet is equipped with a snap-ring, install up to ring. if the air Jet is set too far back from the

base of the nozzle, blast action will take place Inside the gun body causing excessive wear and

reduced efficiency.

2. Inspect pump packing. Check for leaks at shaft. If leaking, refer to pump rebuilding section of this

manual.

DOOR CABLE REPLACEMENT INSTRUCTIONS

\

The counterbalanced vertical door has been designed to ensure maximum operator safety. Dual

independent cables and an emergency stop unit provide this safety. When servicing the cables or any

part of the door system, keep in mind that when disassembling the system, you are disarming these

safety features. PLEASE BE VERY CAREFUL AND FOLLOW THESE SAFE INSTRUCTIONS I

1. With door In closed position, remove counterweight shroud.

2. Raise door until approximately half open. The door must now be held open by blocking it up with a

rigid member (Example: 2" x 4" piece of wood). Provide a second back-up block clamped in place to

ensure maximum safety in the event the first block is disturbed. Raise or lower door until door rests

securely on block.

3. Using a fork truck or rigid table, support under the counterweight.

Be sure the counterweight is level so It will not tip over when cable support Is removed.

4. Remove cable clamp at each end of one cable. Work on one cable at a time. This will provide back-

up support via the second cable. Replace cable with special high grade aircraft approved wire rope

only. Inspect cable clamps; replace If worn or damaged. With cables removed, Inspect "Emergency

Stop Unit". When the cable Is removed, the unit should hinge forward with adequate force. If unit is

functional, clean and lightly 011with spray type penetrating oil. If unit Is frozen, clean or replace.

5. After replaCing both cables, check cable clamps at each end to ensure tightness. Adjust the cable at

the counterweight end If necessary. This Is done by raiSing or lowering the cable "eye bolt" in its

support. Tighten jam nuts when counterweight is properly adjusted.

6. Test door by raiSing and lowering several times; adjust if necessary. Replace schroud.

WINDOW INSTALLATION

For easy seal installatlon, window panel opening isrubbed with a soap and water solutlon. Then startingalong the top, the body channel of the seal is fitted overbody panel edge.

Seal is continued around perimeter of body panelopening-panel channel of the seal enveloping panel edgein a snug fit. then cut the seal to overlap by 118" per footof body opening. This assures a tight fit.

Seal Is withdrawn slightly at the starting point in such away that matches the overlap. Ends of the seal arebrought together and are then forced over the bodypanel. the result Is a tight, smooth joint

Seal is designed with glass channel lip opened at 450 foreasy installation of glass panel. Starting from lowercomer glass panel is fitted into channel as far as it will gowithout forcing.

WorKing in both directions from starting point, speciallydesigned installation tool lifts glass channel lip whileglass is easily slipped into position.

At final comer this same handy tool opens glass channelto permit entry of remaining glass edge. Entire operatlonrequires but a few minutes.

WINDOW INSTALLATION

With a small brush, soap and water solution Is applied tothe seals filler channel. This preparation greatlyfacilitates final operation of installing filler strip.

At top, away from seal joint, filler strip and eye of tool areinserted into seal's filler strip channel. End of filler strip isheld in position with thumb during first motion of tool.

When starting point is reached, the tool is removed. Fillerstrip should be cut to overlap starting point so that whenboth ends are forced Into place, joint will be underpressure.

Filler strip is inserted into handle and eye of speciallydesigned filler strip installation tool. Both handle and eyeso constructed that they prevent filler strip from twisting.

Tool Is moved along channel with zipper-like motion.Filler strip feeds through handle and eye, threads intochannel. Rounding comers is easiest when tool is"wiggled" slightly.

Spur on handle is used to compress filler strip overlapinto channel for a tight joint. Spur also useful In repositionany part of filler strip not properly seated.
