REMOVE GRINDER FROM WOOD PALLETRemove the grinder base from the wood pallet. This isaccomplished by unbolting the bracket that holds eachbase leg to the bottom of the wood pallet. The four level-ing screws are seated in countersunk holes in the woodpallet. To remove the grinder from the pallet, you mustfirst lift one end of the base high enough so both levelingfeet are out of their countersunk holes. Then prop thisend up with several 2x4's so the leveling feet on this endare held out of the countersunk holes. Then lift the otherend out of the countersunk holes and lift grinder off thepallet.

THE UNIT WEIGHS 880 LBS. TOLIFT, USE POWER EQUIPMENTOR GET HELP TO LIFT THE UNIT.

POSITION BASEThe ACCU-Spin will require an operating area about 150"x 108"D x 80"H. The mower reel will be lifted from behindthe machine, and the machine operator will operate theunit from the operator's position on the opposite side ofthe unit. Position the base to allow sufficient operatingroom in both front and behind the machine. See FIG. 4.

The base should be placed on a relatively level concretefloor, with ample ceiling height to allow for the installationand operation of the reel elevator. Do not place the unitacross two concrete slab seams or across a large crack. Ifthe unit must be placed near a wall, we recommend thewall be located as per FIG. 4.

IMPORTANT GROUNDING INSTRUCTIONS

In case of a malfunction of breakdown, grounding reduces the risk of electrical shock by providing a pathof least resistance for electrical current.

This Grinder has an electrical cord with an equipment grounding conductor and a grounding plug. Theplug must be plugged into a matching outlet that is properly installed and grounded according to all localor other appropriate electrical codes and ordinances.

Before plugging in the Grinder, make sure it will be connected to a supply circuit protected by a properly-sized circuit breaker or fuse.

Never modify the plug provided with the machine--if it won't fit the outlet, have a proper outlet and circuitinstalled by a qualified electrician.

ALWAYS PROVIDE A PROPER ELECTRICAL GROUND FORYOUR MACHINE. AN IMPROPER CONNECTION CAN CAUSE ADANGEROUS ELECTRICAL SHOCK. IF YOU ARE UNSURE OFTHE PROPER ELECTRICAL GROUNDING PROCEDURE,CONTACT A QUALIFIED ELECTRICIAN.

Use only a qualified electrician tocomplete the installation.

MAINTENANCE & LUBRICATIONDAILY MAINTENANCE IS SPECIFIED ON PAGE 4OF THE OPERATOR'S MANUAL, AND IS TO BEPERFORMED BY THE OPERATOR. LISTEDBELOW ARE PERIODIC MAINTENANCE ITEMSTO BE PERFORMED BY YOUR COMPANY'SMAINTENANCE DEPARTMENT:

1. Check gib plate adjustment in the grinder carriagebase monthly. See Troubleshooting Section foradjustment.

2. Check the brushes on the auto traverse drive motorand spin motor once a year. Replace as necessary.See Troubleshooting Section.

3. Check the free play in the grinding wheel shaft bearingonce a year. Replace if excessive play exists.

4. Lift the bellows, (See FIG. 26) and wipe off thetraverse driveshaft and the bearing rails monthly.When a squeaking noise is coming from the actuatorbearings, follow the lubrication procedure for actuatorand linear bearings. Generally, this will be every sixmonths to a year.

LUBRICATION OF ACTUATORAND LINEAR BEARINGSSTEP 1--Thoroughly clean all three shafts.STEP 2--Flood spray all three shafts with a spray lubricant(do not use a teflon based lubricant) until the lubricant isdripping off the shafts. Then run the carriage back andforth through its range of travel. This will carry thelubricant into the actuator and bearings.NOTE: Because of the flood of lubricant you may find thatthe actuator slips and traversing is erratic or stalls. This isnot a problem as it will be corrected in thesubsequent steps.STEP 3--With a clean rag, wipe off the excess amountof lubricant from the shafts. Run the carriage backand forth through its range of travel and wipe the shaftsafter each traverse. Repeat until the shafts are dry tothe feel. This completes the lubrication process.

LUBRICATION FREQUENCYThe lubrication frequency is to check the shaft monthlyduring grinder operation or more often if a squeakingnoise is coming from the actuator.If the unit will be shut down for an extended period of time,more than two weeks, then the shafts and other appropri-ate parts of the unit should be flooded withlubricant and that lubricant left in place until the unit isbrought back into service. When the unit is brought backinto service the full lubrication procedure as stated aboveshould be repeated.

FEED SCREW LUBRICATIONOn a monthly basis spray a lubricant onto the vertical andhorizontal screws and also the motorhead infeed andheight adjustment screws.

ADJUSTMENTSTO REPLACE THE LINEAR ACTUATOR BEARINGSNOTE: Never remove the linear actuator from the driveshaft. Only remove the bearings from the actuator block.

1. Crank the horizontal handwheel until the carriage is allthe way forward (toward the operator position).

2. Turn the actuator release lever 1/2 turn clockwise torelease the linear actuator bearings from the drive shaft.Slide the actuator release lever out of actuator barassembly by loosening the retainer shaft collar, whichpreloads the holding spring. See FIG. 28 & 29.

3. The actuator mounting screw (FIG. 27) on the top side ofthe carriage base. Remove the mounting screw, todisconnect the linear actuator from the carriage.

4. Slide the grinding head to the side, exposing the actuator.5. Remove the shoulder bolts holding the six bearings

(three on each side) to the actuator block. Remove theold bearings and discard them, but save the insidewashers and shoulder bolts.

Inspect the hole from which the bearing and shoulderbolt were removed, for foreign matter. Clean thoroughly.

6. Wipe the drive shaft clean and dry.

IF OIL IS LEFT ON THE DRIVE SHAFT, THEPULLING FORCE MAY HAVE TO BE SET TOOHIGH IN THE FOLLOWING PROCEDURE. THISWILL SHORTEN THE BEARING LIFE.

7. Insert the shoulder bolts through the new bearings andthrough the inside washers (saved in Step 6). Theninstall the complete bearing assemblies into the actuatorblock and tighten the shoulder bolts.

BE VERY CAREFUL NOT TO CROSS-THREADTHE BEARING BOLTS!

8. Slide the carriage over the actuator, and line up the holein the carriage with the tapped hole in the top of theactuator block. Insert the actuator mounting screwthrough the self-adjusting bearing, and tighten the screw.

ADJUSTMENTS (Continued)TO REPLACE THE LINEAR ACTUATOR BEARINGS

9. Install the actuator release lever into the actuator barassembly. Turn the actuator release lever counter-clockwise 1/2 turn to engage the actuator.

10. Connect a spring scale so it pulls on the carriage parallelto the drive shaft. Hold the drive shaft from rotating whileyou pull on the carriage. See FIG. 30.

To overcome the actuator, the pulling force should be 45to 60 lbs (20-27 kg), with 50 lbs (23 kg) being ideal. Ifnot within those specifications, the actuator tension mustbe adjusted. See "Adjusting the Pulling Force" below.

EXCEEDING 60 LBS FORCE WON'T GREATLYIMPROVE DRIVE PERFORMANCE - AND IT WILLSHORTEN THE BEARING LIFE.

Adjusting the Pulling Force:

If the pulling force is not within specification (Step 10 above),adjust it:

1. With the actuator bearings engaged to the drive shaft,readjust the two outboard screws with spring that hold theactuator together. To reach these screws, you mustremove the actuator bar assembly. See FIG. 27. Turneach outboard screw an equal amount when resetting.Turn clockwise for more tension.

2. Check the force again (repeat Step 10 above). Continueadjusting and rechecking until within specification.

NOTE: The factory-adjusted position to reach tensionspecifications is to compress the spring until there is.22 in. (5.5 mm) clearance between the washer and theactuator block. See FIG. 31. Use this as a starting pointunless you are already close to the specified tension.

3. When the tension adjustment is correct, reinstall theactuator bar assembly and actuator release lever.

IF THE ACTUATOR RELEASE LEVER ISTIGHTENED TOO MUCH, IT WILL CONTACTTHE OUTBOARD SCREW HEADS ANDOVERRIDE THEIR ADJUSTMENT, WHICHCOULD CAUSE A TRAVERSE MALFUNCTION.MAKE CERTAIN THAT YOU HAVE FULLENGAGEMENT WHEN YOU REENGAGE THEACTUATOR.

FIG. 30

ADJUSTMENTS (Continued)TO REPLACE THE CARRIAGE LINEAR BEARINGS

NOTE: Set a small bench or table near the centerfront of the machine for use in the following procedure.

1. Remove the carriage bellows from the carriage.Remove the actuator release lever from the linear actuatorand remove the sholder bolt from the top of the carriage.

2. Remove the complete carriage assembly from the machine:A. Crank the carriage forward further until you expose the

actuator mounting screw (FIG. 33) on the top side of thecarriage base. Remove the screw, to disconnect theactuator from the carriage.

B. Remove the bolts which secure the front and rear carriagerails to the Grinder base (six screws for each rail, accessiblefrom beneath the machine).

THE CARRIAGE ASSEMBLY WEIGHSABOUT 40 LBS (18 KG). IF NECESSARY,GET HELP FOR THE FOLLOWINGSTEPS.

C. Lift the complete assembly (carriage, carriage shafts,vertical column, and grinding head) out onto the table in

front of the Grinder. Be careful you don't damage themotor cord.

3. Lift the carriage and slide the rails out of the bearings, one ata time.

4. Remove the three linear bearing pillow blocks (four screwseach) from the bottom of the carriage, and discard them.

5. One at a time, slide the three new linear bearing pillow blocksonto a carriage rail.

6. Adjust the tension screw (FIG. 34) on the side of each bearingblock so that when you radially rotate the pillow block aroundthe carriage (See FIG. 35) rail there is no free play betweenthe bearing and rail. You should feel a strong drag.

Repeat this adjustment to all three pillow blocks, and thenremove the pillow blocks from the carriage rail.

NOTE: The tension is too tight if you feel a cogging actionwhen you rotate a pillow block around the rail. Thiscogging is caused by the bearing skidding on the rail.Rocking the bearing block back and forth should be asmooth uniform motion.

BEARINGS WHICH ARE TOO TIGHT OR TOOLOOSE WILL CAUSE POOR GRINDING QUALITY.BEARINGS WHICH ARE TOO TIGHT WILL ALSOHAVE A MUCH SHORTER LIFE, AND COULDDAMAGE THE RAIL.

ADJUSTMENTS (Continued)TO REPLACE THE CARRIAGE LINEAR BEARINGS7. Attach the three linear bearing pillow blocks loosely to the

bottom of the carriage, with their tension adjustmentscrews (FIG. 34) facing outward.

8. Clean the carriage rails.NOTE: The two rails are interchangeable and are alsoreversible (end-for-end).

9. Insert a rail through the rear two pillow blocks, and alignthe rear pillow blocks to each other with a straight edgelaid along their sides. See FIG. 36. When aligned,tighten the four socket-head screws which hold each rearpillow block. Slide the other carriage shaft through thefront bearing, but do not tighten the socket head screws.

10. Lift the complete carriage assembly back onto theGrinder main base, and secure the rear carriage rail to itsV-groove bosses with the six bolts.

11. With the front rail resting in the V-groove bosses and thecarriage approximately centered on the machine, tightenthe two outside socket-head screws which secure thefront pillow block. Lift the front of the carriage, andtighten the two inside pillow-block screws. Secure thefront carriage rail to its V-groove bosses with the six bolts.

12. Recheck the bearing tension. The tension is correctwhen you try to lift the carriage and can feel no freecarriage movement up or down.Check for excessive carriage-traverse load by using aspring scale to pull on the carriage parallel to the driveshaft (as in FIG. 30). There should be only about a 3- to5- lb. pulling force.To double-check, manually slide the carriage assemblyfrom one end of its travel to the other. There should beuniform resistance through the full range of travel.

13. Slide the linear actuator under the carriage, and line upthe hole in the carriage with the tapped hole in the top ofthe actuator block. Insert the actuator mounting screwthrough the self-aligning bearing, and tighten it.Be careful not to cross-thread the screw.

14. Reinstall the actuator release lever into the linear actuator.15. Reattach the two carriage bellows. Refer

to the assembly section of this manual.

TO ADJUST THE CARRIAGE GIB PLATE

The gib plate must be readjusted occasionally to elimi-nate free play. Otherwise, the grinding head can movefrom side to side, and the reel may be ground unevenly.

The gib must allow the carriage to be cranked freelyforward and back without any side play. See FIG. 37.

To adjust:

1. Crank the carriage all the way forward (toward theoperator position).

2. Tighten the front gib screw until the carriage has noside play but the horizontal handwheel can still becranked.

3. Crank the carriage gradually back (away from theoperator position), and adjust the remaining gibscrews as you go.

(Right Traverse) Forward Torque--Factory set at full (CW) 4:30. Do not change this setting.(Left Traverse) Reverse Torque--Factory set at full (CW) 4:30. Do not change this setting.

IR COMP--Factory set to 9:00. IR COMP is current (I) resistance (R) compensation (COMP).IR COMP adjusts the output voltage of the drive which balances load to motor RPM. Regulation of a traversemotor may be improved by slight adjustment of the IR COMP trim pot clockwise from its factory-set position.Overcompensation causes the motor to oscillate or to increase speed when fully loaded. If you reach such apoint, turn the IR COMP trim pot counterclockwise until the symptoms disappear.

Max. Speed--Set at 3:30 for maximum voltage of 90 Volts DC to the traverse motor. When voltage is above 90volts DC, the traverse motor will start to pulsate and not run smoothly.

(Right Traverse) Forward Acceleration--Factory set at full (CCW) 8:30. Do not change this setting.(Left Traverse) Reverse Acceleration--Factory set at full (CCW) 8:30. Do not change this setting.

(DB) Dead Band is the potentiometer setting for the 50 or 60 Hz cycle control. Factory set to 9:00, works forboth 50 and 60 Hz. Do not change this setting.

Calibrating the DWELL TIME rotary DIP switch adjusts the amount of time the process remains in the stopposition after a limit switch is actuated. The DWELL TIME range is adjustable from 0 - 4 seconds. A DIPswitch setting of 0 sets the DWELL TIME to 0 seconds, while a setting of 8 sets the DWELL TIME to 4 sec-onds. Dwell time is preset to #2 setting for a 1 second dwell time when reversing at each end of stroke.

Diagnostic LED's indicate the function that is currently being performed:

* POWER indicates that ac power is being applied to the control.* FORWARD indicates that the process is running in the forward direction (traversing left).* REVERSE indicates that the process is running in the reverse direction (traversing right).* PROX 1 FWD LIMIT lights when the forward limit switch is actuated (left prox).* PROX 2 REV LIMIT lights when the reverse limit switch is actuated (right prox).* DWELL lights when the process remains stopped after a proximity switch is actuated.
