The three (3) motorshaker has an adjustable dual motion drive allowing the user to switch between linear and balanced elliptical motionwhile unit is in operation.Each unit has a fluid distribution box. Options include: Header Box Possum Belly with Butterfly Valve Possum Belly with Knife GateNOTE: Refer to the Installation, Operation and Maintenance manuals for further details.4

FLUID DISTRIBUTION SYSTEMSShaker with Header Box The fluid distribution system is at the rear of theshaker basket and is mounted above the screendeck. (Refer to Figures 1 and 2.) Fluid is redirected from the inlet line throughthe header box into a half pipe at the rear ofthe basket. Since fluid distribution is mounted above thescreen deck, no trap exists to collect solids. As fluid passes through the diverter box, itsweeps the box clean.Figure 1Carbon Steel Header BoxShaker with Possum Belly with Butterfly Valve Bypass The butterfly valve is located below the main inlet onthe possum belly. (Refer to Figure 3.) Use to manually open or close the bypass. When CLOSED, fluid flow is directed through thepossum belly to the shaker bed. OPEN the bypass by turning butterfly valve 90 . When butterfly valve is opened, fluid is redirectedinto the skid bypassing the screens.Figure 2Stainless Steel Header BoxFigure 3Possum Belly with Butterfly Valve5

Shaker with Possum Belly with Knife Gate Bypass The pivoting knife gate for single shakers is manuallyraised or lowered to operate the bypass. (Refer toFigure 4.) When the knife gate is opened, fluid is redirected into theskid bypassing the screens.Dual & Triple Shakers with Common Possum Belly withKnife Gate Bypass The knife gate is controlled by a single, turninghandwheel. (Refer to Figures 5 & 6.) When the knife gate is opened, fluid is redirected into theskid bypassing the screens. The manually operated slide gatesare also used to control the flow rate.Figure 4Possum Belly with Knife Gate BypassFigure 5Dual Shaker with CommonPossum Belly with Knife GateFigure 6Triple Shaker withCommon Possum Bellywith Knife Gate6

Quad Shakers with Feed Manifold Assembly, Header Boxes &Butterfly Valve Bypasses Mud feeds into the back of the feed manifold assembly with the flow evenly distributed to each of the headerboxes. (Refer to Figure 7.) Butterfly valves located at each header box are used to open or close flow to a particular shaker. Butterfly valves located at the top of the feed manifold are used to close off flow to shakers enabling the use of acement bypass.Figure 7Quad Shaker with Feed Manifold Assembly,Header Boxes & Butterfly Valve BypassesSECTION 2.0 PREPARATIONUNPACKINGInspect all goods as received from shipping company BEFORE setting up and operating the shale shaker.

PRESERVATION & STORAGEStorage of Non-Commissioned EquipmentEquipment can be stored (upon arrival) in the shipping crate for a 12 to 24month preservation period. Do NOT expose equipment to dust, vibrationor extreme weather conditions (such as heavy rain). If unit has been removedfrom original crate, cover with a tarpaulin during any preservation period.Storage of Commissioned Equipment Figure 15Amp MeterReinstall original shipping brackets to protect equipment.When disconnecting power connections to control station and motors, plug all inlets with an appropriatefitting to keep water/moisture from entering. Do NOT leave any electrical connections open and exposed.Add anti-condensation packs to motor J-Boxes and control station.Install and seal all control station doors and J-Box Covers.NOTE: Using Hercules Real Tuff Thread Sealant with Teflon (MSDS NS5820 A.5.4) on plug threads helps to prevent leakage. (Refer to Figure 16.)DECOMMISSIONING PROCEDURESWARNINGFigure 16Sealant Used on Plug ThreadsWhen decommissioning shaker, shut off and lock out power BEFORE removingguards (brackets, skirt, etc.). Follow all local and national electrical codes. Failureto comply could result in severe personal injury or property damage. Lockout ofpower MUST be done by a certified electrician. Wash unit and remove screens from skids.Disconnect flow line from feeder and main power lines from control panel.Attach shipping brackets to baskets and skid.Move or transport shaker via lifting points indicated on skid.3.0 OPERATING INSTRUCTIONSADJUSTABLE PARAMETERS DURING NORMAL OPERATING CONDITIONSScreen Selection 12Selection of screen mesh depends on a number of factors:flow rate, fluid condition, formation, rate ofpenetration (ROP), fluid type and number of shakers.Use the finest screen possible to ensure optimumperformance to the relative screen life.

Flow Rate Adjust flow rate to maintain a constant pool level on allshakers used. The optimal fluid end point is 75% ofscreen surface.1-1/4”NutBasket (Deck) Angle The basket deck angle is manually adjustable between -3 degreesand 3 degrees. (Refer to Figure 17.)NOTE: Shut down of shaker before changing deck angle isNOT necessary.ATTENTIONDo NOT use air/pneumatic ratchetor wrench to adjust deck angle jack.CHANGING BASKET (DECK) ANGLEIMPORTANT: Do NOT adjust more than 2 degrees per sidewhile changing deck angle.AdjustableBetween -3Degrees & 3DegreesFigure 17Basket (Deck Angle) Use a manual ratchet, wrench or screen clamping wedge to adjust the 1-1/4” nut located on top of jack.Adjust each side to desired position. Set each side to the SAME angle. Locate manual jacks on discharge end of shaker and set basket at any angle between the highest andlowest angle.NOTE: Lower angle settings result in longer screen life and wetter cuttings. Higher angle settings result in driercuttings and increase fluid capacity. Reset fluid end point by adjusting basket angle or by careful selection of mesh size.NOTE: Always operate shaker with lowest possible basket angle to meet capacity requirements. A steep inclineresults in screen overload and decreased screen life.13

SHAKER SPEEDThe shaker is designed to operate at 1,500 rpm (with 50Hz motor) or 1,800 rpm (with 60Hz motor) in both water andoil based mud.Two (2) Motor Control Panels The two (2) motor control panel has START and STOP. This panelis used ONLY on linear motion shakers. (Refer to Figure 18.)RedSTOPButtonThree (3) Motor Control Panels The three (3) motor control panel has a selector switch foroperation as either a linear or elliptical motion shaker. Switch between linear or balanced elliptical motion to change themotion of the shaker. (Refer to Figure 19.)Green STARTButtonRed STOPButtonLinear or EllipticalSelector SwitchGreenStartButtonFigure 18Two Motor Control PanelATTENTIONUnit shutdown is NOT necessary whenswitching between linear & ellipticalmotion.Figure 19Three Motor Control PanelEQUIPMENT START-UPATTENTIONMake sure all objects (such as tools) are clearfrom equipment BEFORE starting unit. Ensure screens are properly installed and firmlywedged into place. (Refer to Figure 20.) Wet screens with base fluid PRIOR to runningdrilling fluid.14Figure 20Screens & Wedges Firmly In Place

Ensure a gate is placed at any unused effluent stream outlet (of the skid), and desired outlet is unobstructed. Check all electrical connections. Turn unit control panel to LINEAR or ELLIPTICAL (if unit has a 3rdmotor) depending on drilling parameters. Push START button on control panel to start shaker. Allow fluid to flow over shaker screens.NOTE: Apply flow of fluid slowly at first to avoid flooding screens. Keep fluid end point at 75% coverage of the screening surface for optimal performance.WARNINGKeep all guards in place at all times to avoid exposure to parts rotating at highspeeds. While power is on, severe injury can occur if hands or feet reach inside unit.CONTROLLED SHUTDOWN Close off flow to feeder.Continue to run unit until drilling fluid already on screens is processed.Thoroughly clean baskets and screens using appropriate base fluid.Push STOP button on the start/stop station.CAUTIONFollow ALL safety instructions. Use PPEequipment when using steam or pressure equipment.NOTE: Do NOT use a squeegee or any other foreign object to clean screens.NOTE: If unit is out of use for long periods, remove; clean thoroughly; dry; and, either re-box or store all screens in asafe, dry area.SCREEN HANDLINGScreen Installation ProceduresMongoose units have four (4) pre-tensioned screens and ten (10) wedges per shaker basket (with two spares on thecable tower). The Meerkat units have three (3) pre-tensioned screens and eight (8) wedges per shaker basket. Oncescreens are placed on the screen bed, wedges are driven between each screen edge and support bars on shakersidewalls. The screen bed is slightly crowned at the center causing screen frames to bow when wedges are forced inplace. This prevents screens from “whipping” up and down during shaker operation.CHANGING/INSTALLING SCREENSATTENTIONWash down screen areaPRIOR to installing new screens.15

Stop flow of drilling fluid to shaker. While shaker is running, wash down screens. Clean all cuttings andsolids build up around inside of deck and wedges.Shut down shaker.WARNINGPerform lockout/tagout procedures to isolaterig power supply.ATTENTIONUse a rubber mallet to avoid damage to wedges. Each screen is secured in place by two (2) wedges (one per side). Arubber mallet is required to remove wedges. A rubber mallet blowto end or to top handle section can remove wedges.NOTE: Due to the position of the motor tube on the Meerkat units,an extra screen wedge (supplied with shaker) can be used as anextension with the rubber mallet to assist in the removal of themiddle screen. Turning the extra wedge on its side providesadditional working space enabling the operator to avoid possiblepinch points. (Refer to Figure 21.) Figure 21Meerkat Screen RemovalRemove screen panel. Screen panels are removed and installed oneat a time.NOTE: Repeat the following steps for each additional screen panel. Wedges for the second screen from the feed end are REVERSEDfor easier installation. Wash down screen bed and gasket prior to installing new screens. (Refer to Figure 22.)Figure 22Screen Deck GasketsATTENTIONReplace any deck gaskets if worn,cracked or hardened. Lay new screen into shaker deck. Position one wedge between screen edge andsupport bar on shaker side wall. (Refer to Figure 23.) Position other wedge onopposite side in same manner and hammer tight.ATTENTIONBoth wedges must be in position PRIOR to hammering them tight.Failure to due so will prevent the second wedge from being started. 16Wet down new screens with base fluid PRIOR to use of drilling fluids.Figure 23Wedge PositionedBetween ScreenSurface & Support Bar

Screen Washing & BlindingCAUTIONFollow all safety instructions. Use PPEequipment when cleaning unit.ATTENTIONNEVER use a wire or stiff fiber brush on screens. Wash screens with appropriatemedium BEFORE shaker unit is shut down to avoid plugging orblinding meshes by dried solids.SCREENS PLUGGED WITH SOLIDSWash screens from back side using base fluid with screens REMOVED from shaker. Change screens to a finer mesh.Screen StorageATTENTIONAvoid mechanical damage. Always washscreens PRIOR to storing them. Store screens in original cardboard packaging to protect screen mesh.Horizontal or vertical stacking is permissible.SECTION 4.0 PREVENTATIVE MAINTENANCESAFETY RELATED MAINTENANCE PROCEDURESWARNINGBEFORE starting any parts replacement procedure or general maintenance, initiate acontrolled shutdown. Lockout/tag out unit. Have a certified electrician ensure powersupplies are isolated BEFORE performing any maintenance on unit. Clean all parts and work area.Block up and secure heavy parts BEFORE working beneath unit or parts.Where heavy lifting is involved, always seek assistance.Remove all screens BEFORE any work is carried out on shaker.Ensure all tools, old parts, nuts, bolts, washers, etc. are removed BEFORE restarting unit after maintenance.Do NOT weld on any part of basket assembly.Use only qualified personnel to perform maintenance.Visually examine unit for signs of wear and/or damage. Repair/replace as necessary.Clean unit removing any solids build-up.Perform audible checks, investigating as necessary.17

MOTOR MAINTENANCENOTE: Refer to the “Martin Motomagnetic Operator’s Manual” in the Installation, Operation & Maintenance (IOM)manual for detailed maintenance to the vibrator. Installation of vibrator should be done by a certified electrician.Lubricate Motor Bearings (Every 3000 Operational Hours)ATTENTIONOnly use Kluber Isolflex Topas NB 52 lubricant for bearings.Failure to do so will void the motor warranty. Remove plugs (one for each bearing) and insert an 1/8” NPT Zerkgrease fitting. (Refer to Figure 24.) Pump .882 ounces (25 g) of lubricant into each bearing for normal,bearing surface temperatures below 195 F (91 C). Do NOT over grease.Motor Bolt Torque (Refer to Figure 25.)Figure 24Grease FittingsWARNINGNEVER reuse motor installation hardware (ie. bolts, washers andnuts). Always use new bolts. Check and re-torque new bolts afterfirst four (4) hours of run time.NOTE: There are a total of four (4) motor bolts per each motor whichare torqued to the proper requirements when shipped from factory. Using a 30 mm socket (3/4” drive) with a 200 mm (8”) extensionapply a torque of 435 N-m (320 ft.-lb.) to all LARGE motormounting bolts. Using a 24 mm socket (1/2” drive) with a 200 mm (8”) extensionapply a torque of 245 N-m (180 ft.-lb.) to all SMALL motormounting bolts. Verify and document motor bolt torque every 672 hours or 1 time per month of operation for bolts already inuse in the field.Figure 25Motor Bolts – Four Per MotorMotor - Electrical Connections (Isolators)Any time motor leads are changed or cable is replaced, ensure black neoprene vibration isolators are installedproperly BEFORE operating unit.CAUTIONIsolators are removable, but should always be in place when unit is in use toprotect electrical connections in the motor. Failure to do so causes prematurewiring failure or mounting post breakage.18

Install the thin isolator first. (Refer to Figure 26.) Connect motor leads to the correct terminals. Place the thick isolator on top of motor leads.(Refer to Figure 27.) Place cover on and tighten bolts.ISOLATION SPRINGSFigure 26Thin Isolator - Motor LeadsShowingFigure 27Thick Isolator – Motor LeadsNot ShowingNOTE: There are four (4) isolation springs per basket. (Refer to Figure 28.)Inspection for Fatigue & Replacement Check each spring for signs of fatigue or fracture every 3 months, or ifshaker basket is tilting side-to-side and cuttings are running to one sideof the basket.ATTENTIONSprings are covered with a protective black nitrile “boot” serving asa safety precaution against bare springs acting as a possiblepinch-point. (Refer to Figure 28.)Figure 28Spring Enclosed in Nitrile Boot Check for spring fatigue by setting basket level and measure the height of each spring. The front two springs should be same height, and the back two springs should be same height.NOTE: Height of back springs may differ from height offront springs.GreaseFittingReplacing Springs Remove all weight from springs BEFORE changing them.Lift basket (with proper lifting device) to remove weight fromsprings.The spring slides out for replacement.GREASING DECK ADJUSTMENT JACKThe deck angle adjustment jacks have a grease fittinglocated on the discharge side of the jack. (Refer to Figure 29.)Once a month, apply 10 shots of a multi-purpose grease intogrease fitting.Run deck angle adjustment up and down twice

The Mongoose* with four screens per basket, and the Meerkat with three screens per basket, along with an adjustable deck angle allows flexible control of fluid pool depth and beach length enabling the user to meet a wide variety of drilling conditions. The unique motor mounting of the two motor shaker vibrators produces a true linear motion.
