IMPORTANT SAFETY INFORMATION We at Harig Products, Inc.
Go to great lengths to make our products as safe as possible; however, the possibility of injury still exists while operating machinery. In virtually every case, injury is the result of: Not knowing how to properly operate the machine.
DISTORT YOUR SURFACE GRINDER TABLE AND EFFECT THE PERFORMANCE OF YOUR MACHINE FOR LIFE. In order to achieve the maximum performance of your new Harig® Surface Grinder, carefully follow these instructions on how to grind the bottom of your magnetic chuck: 1.
□ Check the axis motors for noise or excessive heat. □ Make maintenance recommendations for any potential problems found. Every 5000 hrs of run time: □ Replace the Hydraulic Oil.
Harig® Hydraulic Oil, Single Gallon- Part No. 16211213 Every 6 months. AUTOMATIC DIAGRAMS The main Power switch is located on the right side of the stand. Be sure to have this switch turned “ON”, then momentarily turn the Power “Power” switch on the front panel On/Off to the right to begin operation.

2, B) to remove the wood brace between the table and spindle housing, remove the plastic temporary dust cover from the top of the column and slowly pour 2 ounces (1/4 cup) of way oil (the gallon container in the “standard accessory box”) over the bevel gear. Electrical Connections CAUTION: To prevent personal injury, or extensive machine damage, all electrical services ® must be performed by an authorized Harig distributor.
Violation will void the warranty. 9.1 Ground the machine by connecting the green wire to a satisfactory ground. Neither the building structure nor a hot water pipe is a satisfactory ground. SPINDLE MOTOR-OIL PUMP The spindle motor is turned on by momentarily turning the “Spindle” button towards the ON position. This also starts the oil pump of the lubricating system.
After ½ minute the oil level should rise to the mid-point of the sight glass in the column cap of the machine. The spindle and oil pump are stopped by momentarily turning the “Spindle”. CROSS FEED CAUTION: To prevent damage, check the location of the adjustment dogs below the right side of the table. The dogs must be set very far apart for manual use and as close as needed for automatic Crossfeed use. Achieve manual cross feed by loosening the cross feed travel locking thumb screw (Fig. You may park the table at any time during a cycle. Simply turn the table switch to the OFF position and hold for two seconds.
CHANGING THE DIRECTION OF THE TABLE PARK The table park is set to park towards the right as a default on your grinder. To change the direction of the park turn the “Hydraulic”. The 9A-46-H8-V52 wheel furnished with the machine works well if used with a mist or wet coolant and can be used dry if care is used to prevent heat buildup. If difficulty is experienced, use a still softer and more open wheel such as a 32A46-G12BEP.
® Check th e large oil cup in the rear of the machine. If it is less than half full, add enough Harig Way Oil (Part No. 16211245, furnished with machine) to bring level nearly full. Very 100 hours of operation: Check hydraulic tank oil level. “ hammering” of the out-of round wheel at a different vibration rate.

If a Harig® Accu-Dresser is used to dress an unbalanced wheel, chatter in the finish will result because the wheel is dressed round an d will “hammer”. Ball bearing failure.
He super precision bearings used in the Harig® spindle are sized to give many years of service. If a failure of either the sp indle or motor bearings does occur, chatter will appear on the work being ground, and a noise will be heard when the spindle is running. “Hard-shell” sides on wheel.
Break the corners of the grinding wheel with an abrasive stick. Grinding swarf in coolant. Clean out coolant tank. INACCURATE GRINDIN. Magnetic chuck clamped too tightly or too loosely. A chuck or fixture clamped too tightl y may warp the table, causing it to rock in the saddle ways ther than tracking smoothly.
Long spark out time. If the grinder does not “spark out” after a reasonable number of passes, you may be using an incorrect viscosity oil, use only (Harig® Way Oil) 16211245 The pressure oil ing system floods e ways with so much oil that a higher viscosity lubricant can lift the table a few tenths when light cuts are taken. CAUTION: Electrical connection or services to preclude personal injury or extensive machine damage. All electrical service must be performed by an authorized Harig® distributor Violation will void the warranty. If motors run, check control circuit by turning off current and using an ohmmeter to check control-wiring continuity against the electrical diagram. Spindle housing assembly sticking in column ways.
The exceptional rigidity of the Harig® Grinder is ob tained by an extremely close fit on the olumn ways. Since there is only a few tenths clearance between the spindle housing. If the column way surfaces are clean and smooth and the spindle assembly is still sticking, either the spindle slide back plate has w arped or the column uprights have moved closer together by a w tenths.
If the spindle housing is tight in only a small area, scrape the back ways of the column to remove the high spot. Release plunger before reaching end of travel. If the table will not move by dressing the plunger (Note: Plunger is difficult to push), the valve should be replaced. If the table travels by manually activating the solenoid, proceed to the electrical checks.
