Site Considerations

WARNING:

CAUTION:

DANGER:

The Gilson Testing Screen is a ruggedly-constructed machine that will provide years of service if installed correctly and maintained properly� Most cases of poor operation are caused by faulty installation� Problems can be avoided by careful planning before placing the machine into service�

Anchoring to Concrete Floors

Gilson recommends using lag shield anchors with lag

screws to anchor the machine to a poured concrete oor

(Fig� 1)� However, anytime local codes apply, you MUST follow the anchoring methodology specied by the code�

Machine Elevation

An elevated foundation for the machine allows for easier tray handling� However, this also elevates the loading area�

Space Allocation

Provide enough space around the machine for adequate operator material handling, the installation/removal of the screen trays, and maintenance on the machine�

Physical Environment

The physical environment where the machine is operated is important for safe operation and longevity of machine components� For best results, operate this machine in a dry environment that is free from excessive moisture, hazardous or explosive atmospheres, or extreme conditions� Consider the noise and dust created by the machine and ensure that there is adequate ventilation for safe operation�

Extreme conditions for this type of machinery are generally those where the ambient temperature range exceeds 104°F (40°C) or the relative humidity range exceeds 20%–95% (non-condensing)�

Fig. 1: Concrete Anchoring

Weight Load

NOTE: Install the machine on a level, rigid foundation�

Gilson recommends a poured concrete oor.

Make sure that the surface where the machine is placed will bear the weight of the machine and the weight of the testing materials� Additionally, consider the weight of the operator and any dynamic loading that may occur when operating the machine�

Electrical Installation

Place this machine near an existing power source� Make

sure all power cords are protected from tra󰀩c, material

handling, moisture, chemicals, or other hazards� Make sure to leave enough space around machine to disconnect the power supply or apply a lockout/tagout device, if required�

Installation

Read all safety warning and instruc-

tions before installation. Failure to follow the warnings and instructions may result in electric shock,

re, and/or serious injury.

DO NOT connect the Testing Screen

to an electrical power source until you have mounted

the machine to its intended foundation, veried that

the machine is wired as ordered and is appropriate for your power source.

You must use lifting equipment to lift

Verify Power Requirements

Verify that the Testing Screen is wired as ordered and appropriate for your power source�

Standard Testing Screens are driven by a 115V/60Hz, 1/2hp electric motor requiring 12-15 amps to operate. A dedicated 20 amp circuit is recommended. Machines with model numbers ending in “F” are congured to operate on 230V/50Hz.

Load your desired sequence of screen trays into your

Testing Screen, being careful not to pinch your ngers with

already inserted screen trays� Apply clamping force on the trays�

TS-1/TS-3: Apply short strokes to the hydraulic pump handle� The hydraulic system will apply tension on both sides of the Vibrating Unit Assembly�

8

TS-2: Turn the two clamp rods clockwise simultaneously and as equally as possible using your sense of touch to

determine when the trays are rmly clamped.

IMPORTANT: The machine is turned ON by pushing the

GREEN button and turned OFF by pushing the RED button�

4. Load the Testing Screen� Choose your loading method by considering the nature and characteristics of your sample and the type of dust it will release into the atmosphere�

5. There are two types of tests:

• Agitation of the sample until separation is complete�

• Agitation of the sample for a predetermined period of time�

Sample Capacity

Coarse Aggregates

The quantity of sample to be loaded is established by test

specications and depends greatly on the type of material

and its particle size range�

The ASTM C 136 specication for “Sieve or Screen Analysis of Fine and Coarse Aggregates” calls for maximum screen loadings for 14-3/4 x 22-3/4in (375x578mm) clear screen areas as follows:

ASTM C136 SAMPLE SIZES

Nominal Max. Size of Max. Screen Particle, in (mm) Loadings, lb (kg)

The choice will depend on the nature and characteristics of the sample and on the requirements of the test�

If the test requires complete separation, watch the test progress through the top of the Testing Screen�

To determine whether material is still passing through a ne

mesh screen, insert the clean dust pan tray directly below the screen tray in question� Separation is complete when no particles fall into the tray�

NOTE: If the Testing Screen or the motor is overloaded, a

circuit breaker in the switch could disconnect the power� If the machine stops in the middle of a test, check the switch� If the RED button is halfway out, the circuit breaker has tripped� Determine the cause of the overload and correct it� To restart, push the RED button all the way in, and then push the GREEN button�

6. Turn OFF the machine by pushing the RED button� Unload the various screen trays and dust pan�

NOTE: Loaded screen trays are not as light as they may

appear� Use common sense and proper equipment�

7. Unless you plan to continue operating the Testing Screen, unplug or disconnect it to eliminate a tripping hazard and reduce electrical hazards�

No.4 (4.75mm) 5.7 (2.6) 3/8in (9.5 mm) 11.2 (5.1) 1/2in (12.5 mm) 14.8 (6.7) 3/4in (19.0 mm) 22.5 (10.2)

5.0in (125.0 mm) 148.6 (67.4)

Maximum screen loading for materials denser than limestone aggregates should be adjusted accordingly� Samples can be run in two or more batches if necessary� The capacity of the screen for a given sample is determined by the sample in the tray with the maximum load� A coarse series size tray at completion of sieving should carry a load limit equal to the amount of material needed for one layer of particles over the wire cloth area�

If all tray slots are not required for a test, an intermediate tray may be used to relieve loading on a critical tray and allow the use of a larger test sample� Capacity is a function of volume� Materials such as lightweight aggregate or coal must be tested in somewhat larger amounts by weight�

Many light materials are also soft� Their test times should be limited to avoid degradation of the sample� If you get poor separation or loss of material from the trays should

rst check the amount of sample on the individual screen

tray and adjust the sample size accordingly� Diagnosis should then proceed to checking for proper leveling and looking for worn, broken or out-of-adjustment components as described in the Maintenance section on page 10�

Remember that the ASTM minimum sample weights are for representative samples� Initial sampling should always be done by taking a much larger amount from several areas in a storage bin or stockpile, then combining and reducing the amount to a manageable size by splitting� Gilson Sample Splitters are ideal for this purpose�

9

Fine Aggregates

WARNING:

The Testing Screen is designed primarily for operation in

the coarse size range of 4in to No.4. Separation of ner materials is less e󰀩cient and ne particles may become

trapped behind side liners of trays causing test errors�

For separations of ne aggregates from No.8 through

No�200, loading at completion of sieving should be limited to the ASTM C 136 level of 4g per square inch of sieving surface, assuming a material about the density of sand� This is equivalent to loading 1,350g (3lb) per tray and will

result in machine capacity in the ne aggregate range of

under 20lb per test unless sizes are evenly distributed among the trays�

Somewhat larger amounts of material may be loaded if the Testing Screen is used for mass separation rather than for testing� Sharpness of separation will decrease as loading is increased, and overloads can cause damage to valuable wire cloth�

For applications where test materials are limited to ne

series sizes, or where special screening problems existbecause of softness or density, the Testing Screen may be factory-equipped with a Speed Variation Accessory�

A low-amplitude eccentric shaft is also available and recommended when working exclusively with friable materials�

The capacity of the Gilson Testing Screen is suitable for

most laboratory test sizing work. For eld laboratories where mobility is important, Gilson o󰀨ers a Porta-Screen®�

3. Remove upper guide bearing screws�

4. Loosen the screws in the lower guide bearing and lower

threaded block�

5. Turn the clamp rod counterclockwise until you can pull it up and out of the machine�

6. Remove and inspect the hardened steel wearing plate which rests on the upper Vibrating Unit Assembly frame�

7. Use a magnet to lift one end of the wear plate to the large clamp rod hole� Grip the wear plate with your

ngers or needle-nose pliers, and pull it up through the

hole� If the plate is worn, replace it�

8. To reinstall the wearing plate, drop it through the large clamp rod hole, and use a screwdriver to position it so that the holes line up�

9. If you are replacing only the clamp rod, remove parts from the old clamp rod�

10. Drive the roll pin out of the collar, using a 3/16in drift

punch� Remove the collar and upper guide bearing from the clamp rod, and install the parts on new clamp rod�

The TS-1 and TS-3 hydraulic clamping systems consist of a low-pressure hydraulic pump, two hydraulic cylinders, and two hydraulic clamp rod assemblies�

The systems use a medium-viscosity hydraulic oil such as Shell Tellus 25 or Mobil AW 32�

Disconnect the machine from its power source and lock out the connection prior to performing maintenance and/or repairs�

Checking the Oil

Disconnect power supply before

servicing or cleaning.

DO NOT plug in or operate the

Testing Screen without all covers installed.

To determine the level and quality of the hydraulic oil:

1. Unplug or otherwise disconnect the Testing Screen from its power source, and lock out the connection�

2. Release the pressure in the system by pulling the pump handle all the way toward the front of the machine�

3. Observe the position of the internal pump cover before you remove it� Its vent is slightly closer to the front (handle) end of the pump than to the back� Gilson recommends using a marker or other means to mark the operator side of the cover to ensure correct orientation during reassembly�

4. Remove the ve screws that secure the external pump cover to the top, and lift the cover o󰀨

(Figure 3 on page 8)�

11. If replacing the lower guide bearing, do so now, leaving the screws loose�

12. If the threads on the lower end of clamp rod are stripped, replace lower threaded block� Leave the screws loose�

13. Reinsert the clamp rod, and turn it clockwise until the upper guide bearing rests on the top of the machine�

14. Install upper guide bearings, leaving the screws loose� (crescent washer goes between the head of the screw and the top of the bearing)�Tighten the lower threaded block screws� Finger-tighten upper and lower guide bearing screws; then give each a 360° tightening with a wrench� Front and rear screws on each bearing need to be equally tight� If screws repeatedly loosen during operation, use a small amount of medium-strength (blue) Loctite�

5. The reservoir should be lled to a 1/4in from the top,

and the oil should appear clean�

6. If oil is clean but low, ll tank to correct level and

reassemble�

7. If oil appears dirty, rst replace the internal pump cover. Then drain and rell the system. See Draining and Relling the Hydraulic System on page 12�

Draining/Relling the Hydraulic System

WARNING:

13. Bleed the air out of the hydraulic system:

Disconnect power supply before

servicing or cleaning.

DO NOT plug in or operate the

Testing Screen without all covers installed.

1. Unplug or otherwise disconnect the Testing Screen from

its power source, and lock out the connection�

2. Clean the top of the machine to prevent foreign materials from contaminating the oil�

3. Release the system pressure by pulling the pump handle all the way toward the front of the machine� (If continuing from checking the oil and have removed the external

pump cover, leave it o󰀨.)

4. Remove the top and side/back covers� See Removal of Top and Side/Back Covers on page 11�

5. Disconnect the hose from one of the hydraulic cylinders, leaving the other end of the hose connected to the pump� Place the free end of the hose into a clean container at a level that will allow gravity to empty the system� Pump the handle carefully to drain the hydraulic oil from the system�

a. Loosen the connections between the hoses and the

cylinders by partially unscrewing the swivel connections�

b. Pump up the hydraulic system until oil begins to appear

at the loosened connections�

c. Retighten the swivel connections�

14. If the ttings leak, use hydraulic joint compound to

create a seal between each leaky tting and the pump

or cylinder to which it is attached�

15. Reinstall the covers�

6. Observe the position of the internal pump cover before

removal� Its vent is slightly closer to the front (handle) end of the pump than to the back� Gilson recommends using a marker or other means to mark the operator (front) side of the cover to ensure correct orientation during reassembly�

7. If there is sludge in the bottom of the pump reservoir, remove the pump from the machine and clean it out with

solvent before relling with oil.

8. If repairs are to be made, continue disassembly as described Hydraulic Pump on page 15� If you are only replacing hydraulic oil, continue to the next step�

9. Reconnect the hose to the cylinder�

10. Fill the pump reservoir to within 1/4in of the top�

Replace the pump cover in the same orientation before removal� Pump up pressure with short strokes on the pump handle� Release pressure by pulling the handle all the way toward the front of the machine�

11. Remove the pump cover again and add hydraulic oil to

ll pump reservoir to within 1/4in of the top.

Pressure Release

Port Plugs

Pressure Check

The hydraulic pump is a low-pressure pump with a cast aluminum body (Fig� 7)� If your pump leaks or malfunctions, especially if the machine is old or heavily-used, we strongly recommend that you return it to the factory for repair (a

three to ve day process), or purchase a new pump. Call

800-444-1508 for instructions�

It is sometimes possible to repair pumps in the eld by replacing parts. We DO NOT recommend eld repair unless

you have experience in working with hydraulics�

See the Hydraulic Pump exploded diagram on page 23� The various springs in the pump are NOT interchangeable�

General Hydraulic Pump Repair

Disconnect power supply before

servicing or cleaning.

When working with the hydraulic

pump, take care NOT to score surfaces where seals must be maintained.

1. Unplug or otherwise disconnect the Testing Screen from

its power source, and lock out the connection�

NOTE: ALWAYS observe the position of the internal pump

cover before you remove it� Its vent is slightly closer to the front (handle) end of the pump than to the back� Gilson recommends using a marker or other means to mark the operator (front) side of the cover to ensure correct orientation during reassembly�

3. Remove parts carefully to not damage the pump casting or any parts to be reinstalled� Balls must NOT be nicked or scratched� Clean pump and parts, and dry thoroughly before reassembly�

4. To reinstall balls, tap them gently into their seated positions with a soft-metal, blunt-ended rod�

DO NOT remove or adjust the bypass

assembly. These parts are assembled and preset at the factory. Any change in the bypass pressure can damage the vibrating assembly.

2. Drain the pump. See Draining and Relling the Hydraulic

System on page 14�

15

Hydraulic Pump Troubleshooting

If the system fails to maintain clamping pressure, and no oil is leaking from the cylinder, the failure may be caused by foreign material or dirt in the hydraulic pump (there are

often aluminum ecks in the hydraulic oil from the pump

casting� These are normally of little consequence in pump malfunctions)�

To diagnose problems in the pump, remove the internal pump cover then reduce the level of hydraulic oil� Place a piece of clear plexiglas completely over the reservoir opening and screw it in place� Pump up the clamping pressure and observe where the oil is returning to the reservoir�

Here are four possibilities to look for when diagnosing hydraulic pump problems:

• Observe the holes on either side of the base of the center post� If the oil is returning here, there is a bypass problem� DO NOT attempt to adjust or repair the pump

in the eld. Return it to Gilson for repair or replacement.

• View the pump from above and at the plunger end to see the intake hole (located on a raised shelf on the bottom left side of the reservoir)� Oil is taken in here when the pump plunger is pulled outward from the pump casting� If oil leaks from this intake hole when the pump plunger moves back into the pump casting, then the intake check ball is not seating properly� Remove the intake check ball� Clean it and its seat in the pump casting� Check the ball for nicks or other damage, and replace it if necessary�

• If the pump handle creeps back toward the pump casting after oil has been pumped into the cylinders, oil is probably leaking back into the pump through the pressure check thrust pin and O-ring assembly� Dirt or other foreign material can prevent the O-ring from seating properly� Remove and clean the thrust pin, O-ring, and cavity in the pump to remove foreign matter� Also check the O-ring for nicks or other damage, and replace the

O-ring if necessary. If the pump handle actually ies

toward the pump casting, then O-ring is usually torn, and the assembly should be replaced�

• The pressure release hole is in the bottom of the well, directly behind the center post� Oil normally returns to the reservoir through this hole when the handle is pulled all the way back to release clamping pressure� If oil returns through this hole during pump-up, the problem is with the pressure release pin or the pressure release thrust pin and O-ring�If the Plunger O-rings have been allowed to wear excessively, the hard steel plunger may have scored the cast aluminum plunger bore� This wear condition can not be repaired, and the pump must be replaced�

To remove the plunger and replace O-rings:

• Remove the pump handle retainer pin and the two plunger guide screws�

• Pull and remove the plunger and O-ring assembly�

• Replace the O-rings� Dip the O-ring end of the plunger in hydraulic oil and reinsert it into pump body�

Reassemble the Testing Screen in the reverse order of disassembly� Reinstall all covers� DO NOT plug in or try to operate the Testing Screen without all covers installed�

16

Hydraulic Cylinder Inspection and Repair

WARNING:

The hydraulic cylinders apply force to the clamp rods, which draw the Vibrating Unit Assembly parts together� If the machine loses clamping pressure during operation, and/or if hydraulic oil must be frequently added, inspect the hydraulic cylinders for wear�

Disconnect power supply before

servicing or cleaning.

DO NOT plug in or operate the

Testing Screen without all covers installed.

When working with the hydraulic cylinders, take care NOT to score surfaces where seals must be maintained.

To inspect a hydraulic cylinder for wear:

1. Unplug or otherwise disconnect the Testing Screen from

its power source, and lock out the connection�

2. Drain the hydraulic system. See Draining and Relling

the Hydraulic System on page 14�

3. Remove the three screws securing the cylinder cap (Fig� 8)� The spring is compressed inside the cylinder by the cap, so caution is required� Keep pressure on the cap with your hand as you remove the three screws�

4. Release the pressure on the cap slowly so that the compressed spring does not eject suddenly� Remove the cap and spring�

5. Remove the side access panel near the machine’s base�

6. Grasp the lower section of hydraulic clamp rod with vice

grips and hold it steady while unscrewing the clamp rod hex jam nut�

7. Pull the rest of the cylinder up and o󰀨 the clamp rod.

8. Examine the piston and the two quad rings: One ts in a

groove on the piston ange, and the other ts inside the piston. Replace the quad rings if you nd hydraulic oil above the ange on the piston.

NOTE: It should NOT be necessary to disassemble the

cylinder from its base� Cylinder O-rings rarely need to be replaced�

9. If cylinder O-ring replacement is necessary, use a 3/16in drift punch to drive each of the roll pins through to the center hole until they fall out� Remove the old O-ring� Apply a small amount of hydraulic oil to the new O-ring, and install it� Reassemble�

To reassemble the hydraulic cylinder:

1. Slide the cylinder and base assembly onto the upper end

of the hydraulic clamp rod�

2. Dip the piston in hydraulic oil to lubricate the quad rings, then insert the piston into the cylinder�

3. Install the jam nut and tighten it�

Hydraulic Clamp Rod Assembly

Disconnect power supply before

servicing or cleaning.

DO NOT plug in or operate the

Testing Screen without all covers installed.

Hydraulic clamp rods t through a series of guide bearings

and draw the Vibrating Unit Assembly parts together to clamp trays in place for operation�

4. Insert the spring� Place the cap on the spring and apply downward pressure on the cap�

5. Insert and tighten the screws�

6. Reattach hoses then rell the hydraulic pump. See

Draining and Relling the Hydraulic System on page 14�

7. Reinstall covers� DO NOT plug in or try to operate the Testing Screen without all covers installed�

To check for wear in the guide bearings, apply pressure to the hydraulic cylinders with your hand, front to back and side to side�

If you have removed a cylinder, perform this test on the upper end of the hydraulic clamp rod� If a cylinder (or clamp rod) can be moved more than 1/32in in any direction, you should replace parts in the hydraulic clamp rod assembly�

To replace hydraulic clamp rods and parts:

1. Unplug or otherwise disconnect the Testing Screen from

its power source, and lock out the connection�

2. If you have not done so, drain the system, then disassemble and remove the cylinder� See Hydraulic Cylinder Inspection and Repair on page 17�

3. Working through the access hole near the base of the machine, drive the roll pin out of the clamp rod collar (Fig� 8 on page 17)� Slide the clamp rod collar down to rest on the lower guide bearing�

4. Loosen the upper and lower guide bearing screws�

5. Pull the clamp rod up and out of the Vibrating Unit

Assembly�

6. Replace the worn parts as needed�

7. To reassemble, reverse the procedure, except DO NOT

re-tighten the guide bearing screws� Follow hydraulic cylinder reassembly instructions�

8. Finger-tighten the upper and lower guide bearing screws, then give each an additional 360° tightening with a wrench� Front and rear screws on each bearing need to be equally tight� If screws repeatedly loosen during operation, use a small amount of medium-stregth (blue) Loctite�

9. After fully reassembling the unit with covers installed, run the machine empty for a few minutes� It should run freely and quietly�

18

Wire Cloth and Screen Trays

WARNING:

Check condition of wire cloth and screen trays both before and after each operation�

Wire Cloth

Troubleshooting

Disconnect power supply before

servicing or cleaning.

Testing grade wire cloth is a precision-made material and

should be treated with care. The ASTM E11 specication

permits only very slight variations in average opening and wire diameter of testing grade wire cloth� Abrasion due to normal use and/or improper cleaning and handling can cause the wire cloth to be out of specication to a considerable degree before it appears so� Check the wire cloth

periodically for conformance to specications.

Wire cloth may eventually sag, reducing its e󰀨ective

screening area� Wire with 1/4in and coarser openings is

rigid and self-supporting. No.5 and ner sizes have hooked

edges which interlock with the tray’s side clamps to provide

tension adjustment. Trays with No.16 and ner wire cloth

have wire cloth support strips to minimize wear and distortion� Backup wire cloth can be furnished as an option at extra cost, if additional support is desired� Tray side clamps for hooked edge wire and at wire are NOT interchangeable�

Screen Trays

The life of your screen trays can be prolonged by establishing good procedures for handling and storing trays� Avoid

bumping or bending the corners of the tray anges.

Bent anges “work” during operation of the machine and

will eventually break�

DO NOT plug in or operate the

Testing Screen without all covers installed.

Noisy Operation

Loud knocking during operation often indicates worn connecting rods, rod bearings, or the wristpin assembly� See

Drive Assembly on page 11�

Testing Screen Shuts O󰀨

If either the Testing Screen or its motor is overloaded, a circuit breaker in the switch could disconnect� If the machine stops during a test, check the switch� If the red button extends halfway out, the circuit breaker has tripped� Check

to see that you have su󰀩cient voltage to the machine. If so,

check to see if your sample is too large�

To reset, push the red button all the way in, then push the green button to restart�

Shifting of Materials

An imbalance or out-of-level vibration can cause shifting of material to the sides or corners of trays, decreasing screen-

ing e󰀩ciency. Such shifting is likely to be intermittent,

especially on a new screen� Run the machine empty for half an hour before making drastic changes — the problem may disappear of its own accord� If shifting persists, check the foundation to be sure that all mounting bolts are equally tight� Check also the bottom-to-case bolts�

Tighten mounting bolts on the side to which material is moving� Loosen the opposite side slightly�

Look for bent tray edges and material trapped between vibrating sections� Worn guide bearings, wristpins, and/ or connecting rods also cause shifting of material� Refer to sections on the maintenance of those parts�

Sample material will also shift if the unit is not properly levelled� The internal vibrating assembly will not work properly in a machine that is out of level� See Installation on page 7� If the case is seriously out of level compared to the vibrating assembly, look for worn or misaligned parts�

Sluggish Start-Up or Operation

Check loads on sample trays and total sample weights� See Sample Capacity on page 9�

Inspect V-belts for wear, tension and alignment� Check pulleys for alignment� See Drive Assembly on page 11�
