Like all power tools, there is danger asso-ciated with the Model G1004/G1008 MillingMachine. Accidents are frequently causedby lack of familiarity or failure to pay atten-tion. Use this tool with respect and cautionto lessen the possibility of operator injury.If normal safety precautions are over-looked or ignored, serious personal injurymay occur.


110V Operation

The motor supplied with the G1004/G1008 is adual-voltage 110/120V or 220/240V motor. (Forinformation on operating at 220V, see the sectionfollowing entitled 220V Operation.) Under normaluse, the motor draws approximately 16 amps @110V, therefore it should be connected to a circuitthat is protected by a 20 amp fuse or circuitbreaker. This should be satisfactory for normaluse, while providing enough protection againstmotor damage caused by power surges. Grizzlyrecommends that the circuit you use should bededicated, (i.e., the G1004 or G1008 should pro-vide the only draw from that circuit). If frequentcircuit failures occur when using the millingmachine, contact our service department or yourlocal electrical contractor. You are cautioned thatequipment returned to us for service that showsevidence of being over-fused will be repaired orreplaced totally at the customer’s expense,regardless of the present warranty status.

It is also necessary to connect a cord and plug tothe machine. Be sure that both the plug and cordare rated at 20 amps and must include a ground-ing wire. See Figure 1.

SECTION 2: CIRCUIT REQUIREMENTS

Grounding

In the event of a malfunction or breakdown,grounding provides a path of least resistance forelectric current to reduce the risk of electricshock. This tool must be equipped with an elec-tric cord having an equipment-grounding conduc-tor which must be properly connected to agrounding plug. The plug must be plugged into amatching outlet that is properly installed andgrounded in accordance with all local codes andordinances.

Figure 1. Grounded plug configuration.

If you find it necessary to use an extension cordwith the Model G1004/G1008, make sure the -cord is rated Hard Service (grade S) or better.Refer to the chart in the standard safety instruc-tions to determine the minimum gauge for theextension cord.

The extension cord must also contain a groundwire and plug pin. Always repair or replace exten-sion cords when they become worn.

Extension Cords

Potential for electrical shock hazard, thisequipment must be grounded. Verify thatany existing electrical outlet and circuit youintend to plug into is actually grounded. If it isnot, it will be necessary to run a separate 12A.W.G. copper grounding wire from the outletto a known ground. Under no circumstancesshould the grounding pin from any three-pronged plug be removed. Serious personalinjury may occur.


We have covered some basic electricalrequirements for the safe operation of yourMilling Machine. These requirements arenot necessarily comprehensive. You mustbe sure that your particular electrical con-figuration complies with local and statecodes. Ensure compliance by checkingwith your local municipality or a licensedelectrician.

Potential for electrical shock hazard, thisequipment must be grounded. Verify thatany existing electrical outlet and circuit youintend to plug into is actually grounded. Underno circumstances should the grounding pinfrom any three-pronged plug be removed.Serious personal injury may occur.

220V Operation

The Model G1004/G1008 has a motor which canbe operated on a 220V single phase circuit. Inorder to operate at 220V it is necessary to rewirethe motor connections (refer to the wiring dia-grams at the back of this manual) and to add a220V capable cord and plug. The style of plugyou require will depend upon the type of serviceyou currently have or plan to install. Figure 2shows recommended plug styles.

The motor will safely draw about 8 amps at 220Vunder load, therefore it should be connected to acircuit that is protected by a 15 amp fuse or circuitbreaker. This should be satisfactory for normaluse, while providing enough protection againstmotor damage caused by power surges. Grizzlyrecommends that the circuit you use should bededicated, (i.e., the G1004 or G1008 should pro-vide the only draw from that circuit). If frequentcircuit failures occur when using the millingmachine, contact our service department or yourlocal electrical contractor. You are cautioned thatequipment returned to us for service that showsevidence of being over-fused will be repaired orreplaced totally at the customer’s expense,regardless of the present warranty status.

We do not recommend the use of extension cordson 220V equipment. It is much better to arrangethe placement of your equipment and theinstalled wiring to eliminate the need for exten-sion cords. Should it be necessary to use anextension make sure the cord is rated HardService (grade S) or better.

However, owing to Grizzly’s policy ofcontinuous improvement, changes may be madeat any time with no obligation on the part ofGrizzly. Whenever possible, though, we sendmanual updates to all owners of a particular toolor machine. Should you receive one, we urge youto insert the new information with the old andkeep it for reference.


The G1004/G1008 is a heavy machine, 1,010lbs. shipping weight. DO NOT over-exertyourself while unpacking or moving yourmachine – you will need assistance. Seriouspersonal injury may occur if safe movingmethods are not followed. When moving,always insure that you have enough clear-ance in the path way you intend to take andthat floor and stair structures are capable ofsupporting the combined weight of themachine and the people moving it.

This Milling Machine is shipped from the manu-facturer in a carefully packed crate. If you discov-er the machine is damaged after you’ve signedfor delivery, and the truck and driver are gone,you will need to file a freight claim with the carri-er. Save the containers and all packing materialsfor possible inspection by the carrier or its agent.Without the packing materials, filing a freightclaim can be difficult. If you need assistancedetermining whether you need to file a freightclaim, or with the procedure to file one, pleasecontact our Customer Service.

When you are completely satisfied with the con-dition of your shipment, you should inventory itsparts.

Unpacking Piece Inventory

NOTICEA full parts list and breakdown can be foundtoward the end of this manual. For easierassembly, or to identify missing parts,please refer to the detailed illustrations.

After all the parts have been removed from thecrate, you should have:

• Milling Machine• Tool Box

-Fly Cutter 1-Oil Bottle 1-Screwdriver 1-Wheel Handles 3-Open End Wrench 1

Other featured items will be already mounted to themachine. They include:

-Flood Coolant Pump-Draw Bar-Fly Cutter Arbor-Powerfeed (G1008 only)-Light Fixture

In the event that any non-proprietary parts aremissing (e.g. a nut or a washer), we would beglad to replace them, or, for the sake of expedi-ency, replacements can be obtained at your localhardware store.


Clean Up

The unpainted surfaces are coated with a waxyoil to protect them from corrosion during ship-ment. Remove this protective coating with a sol-vent cleaner or citrus-based degreaser. Avoidchlorine-based solvents as they may damagepainted surfaces should they come in contact.Always follow the usage instructions on the prod-uct you choose for clean up.

Do not use gasoline or other petroleum-based solvents to remove this protectivecoating. These products generally have lowflash points which makes them extremelyflammable. A risk of explosion and burningexists if these products are used. Seriouspersonal injury may occur.

Site Considerations

FLOOR LOADYour G1004/G1008 Milling Machine represents alarge weight load in a 28" x 20" footprint. Mostcommercial or garage shop floors should be suf-ficient to carry the weight. Before moving thismilling machine onto a residential floor inspect itcarefully to determine that it will be sufficient tocarry the load. If you question the strength of yourfloor, you should consider having it inspected forpossible reinforcement.

WORKING CLEARANCESWorking clearances can be thought of as the dis-tances between machines and obstacles thatallow safe operation of every machine withoutlimitation. Consider existing and anticipatedmachine needs, size of material to be processedthrough each machine, and space for auxiliarystands and/or work tables. Also consider the rel-ative position of each machine to one another forefficient material handling. Be sure to allow your-self sufficient room to safely run your machines inany foreseeable operation.

LIGHTING AND OUTLETSLighting should be bright enough to eliminateshadow and prevent eye strain. Electrical circuitsshould be dedicated or large enough to handlecombined motor amp loads. Outlets should belocated near each machine so power or exten-sion cords are not obstructing high-traffic areas.Be sure to observe local electrical codes for prop-er installation of new lighting, outlets, or circuits.

Make your shop “child safe”. Ensure thatyour workplace is inaccessible to young-sters by closing and locking all entranceswhen you are away. Never allow visitors inyour shop when assembling, adjusting oroperating equipment.

All die-cut metal parts have a sharp edge(called “flashing”) on them after they areformed. This is generally removed at thefactory. Sometimes a bit of flashing mightescape inspection, and the sharp edge maycause cuts or lacerations when handled.Please examine the edges of all die-cutmetal parts and file or sand the edge toremove the flashing before handling.

Many of the solvents commonly used toclean machinery can be highly flammable,and toxic when inhaled or ingested. Alwayswork in well-ventilated areas far frompotential ignition sources when dealingwith solvents. Use care when disposing ofwaste rags and towels to be sure they donot create fire or environmental hazards.Keep children and animals safely awaywhen cleaning and assembling thismachine.


Assembly of the G1004/G1008 is straightforward.We have organized the assembly process intosteps. Please follow them in sequence.

The Models G1004/08 feature an R-8 spindlewhich accepts many industrial collets and arbors.

To install a collet or an arbor:

1. Release the latches on the head lid andopen it.

2. Determine the location of the pin inside thespindle.

3. Align the keyway of the collet to the sidewhere you found the pin and insert the col-let or cutting tool’s arbor up into the spindlehousing. Rotate the collet slightly to line upthe keyway with the pin in the spindle bore.


4. Turn the hex head at the top of the drawbar(located on the top, front of the head) clock-wise until the threads at the bottom of thedrawbar mesh with the female threads inthe top of the collet or arbor.

5. When using a collet: Insert the cutter in thehole at the bottom of the collet and contin-ue to tighten the drawbar until both the col-let and cutter are tightly in place. Do notover-tighten the collet. Grasp the rim ofthe front pulley. Hold it tight while tight-ening the draw bar.

To remove a collet or an arbor:

1. Loosen the hex head at the top of the draw-bar (2 or 3 turns).

2. Tap on the top of the drawbar with a softfaced mallet to loosen the collet from thespindle. Hold the collet/cutter with ashop towel from the bottom to prevent itfrom dropping completely out of themachine.

3. Continue to turn the drawbar counterclock-wise until it is free from the collet. Onceloose, remove and replace with yourdesired collet. Remove cutting tools fromspindle when not in use.

Your mill comes equipped with a fly cutter that fitson the 1" stub end of the R-8 arbor (this comesinstalled in the spindle).

To install the fly cutter:

1. Clean any accumulated grease, oil, ordebris off of the R-8 arbor.

2. Fit the fly cutter onto the stub end of thearbor so the keys on the arbor and the key-ways on the fly cutter come together.

3. Secure the fly cutter to the arbor with thecap screw and washer provided. Tightenwith an 8mm Allen® wrench.

4. Install the arbor with fly cutter into the millas described under the heading “Collet orArbor Installation.”

The Knee hand crank is located to the left of theY-axis. It is shipped from the factory with the han-dle installed on the knee gear shaft backwards.To install properly begin by removing the exter-nal retaining ring on the end of the shaft. Slidethe handle off of the shaft and re-install so thatthe handle faces outward.

SECTION 5: OPERATIONS


Graduated Dials

SECTION 6: ADJUSTMENTS

The graduated dials on the handwheels for thetable and fine feed can be indexed or “zeroed” tohelp make accurate and convenient movements.Each dial can be reset or locked with thesetscrew or thumb screw provided.

Example:Suppose you want to drill a series of holesin a workpiece at 0.625" centers. Afterlocating the first hole’s placement anddrilling, you can set the dial of the appropri-ate axis to zero and move the table 0.625".Drill the next hole and proceed as above.

3. Loosen the setscrew on the knurled surfaceof the handwheel dial. Turn the dial until the“0” lines up with the index line. Tighten thesetscrew.

4. Turn the handwheel according to the dis-tance you want to move downward. Eachcomplete revolution equals 0.100".

Locking:For milling operations, the spindle heightcan be locked in by tightening the blacklever on the forward, right hand portion ofthe head.

You have two options for spindle height adjust-ment: a drill press style, levered downfeed and amicro adjustment handwheel. The lever is locatedon the right, forward portion of the head. Themicro adjustment handwheel is to the left.

To operate the feed lever:

Pull the lever toward you. The spindle will godown until you stop pulling or until it hits the depthstop.

To operate the micro-adjustment handwheel:

1. Tighten the knurled locking knob located onthe left side of the headstock and justbehind the fine downfeed handwheel.

2. Locking out the levered downfeed willtransfer control to the handwheel. Thehandwheel will not function if the knurledlocking knob is loose.

Spindle HeightTo calibrate the depth stop:

1. Roll the quill down using the lever handleuntil you reach the desired depth shown onthe scale. Lock the quill with the lever lockhandle. Turn the depth stop nut until itmeets the bottom of the depth stop block.Tighten the jam nut against the bottom ofthe stop nut.

2. Roll the spindle up into the head. Place apiece of paper on the workpiece. Loosenthe knee lock handle and raise the kneeuntil the drill bit or cutter just touches thepaper. Tighten the knee lock.

3. Begin drilling or milling. Note for precisiondepth: set the depth stop shallow of thedesired depth by 1⁄16''. Drill the hole andmeasure. Finish to depth using the finedownfeed handwheel with its graduateddial and use the procedure laid out in thesection above titled: Graduated Dials.

Your Model G1004/G1008 milling machinerequires very little maintenance. A thoroughcleaning, now and again, will increase themachine’s durability and efficiency by removingchips and grime that can gum up moving parts.

An occasional application of a protective spraycoating will keep the table and other bare metalparts from rusting and pitting.

REMEMBER: When performing maintenance orrepairs on shop equipment, always disconnectthe machine from its power supply.

The G1004/1008 milling machine table featurestapered gibs in the dovetail ways. To tighten thetable, loosen the screw at the small end of thetapered gib and tighten the screw at the largeend. Use the same procedure for the saddle andknee gib adjustments.

Spindle: Add oil to the oil cup after every 4 hoursof use. The cup is located on the right portion ofthe milling head just under the belt guard. SAE 20oil is recommended.

One Shot Lubricator: Located on the left side ofthe knee. Check periodically and fill oil reservoiras necessary with SAE 20. This lubricator willsupply oil to the knee, apron and table slides. Bypulling the lever you will apply enough oil for a 4hour period of use.

Flood Coolant System: For best results it is rec-ommended that a water soluble oil be used.Replace coolant when it becomes noticeably con-taminated or rancid. Take the time to clean thesludge from the bottom of the tank annually.Access to the tank may be made from the right orleft panels on the stand/base.

Table and Apron Lead Screws: Lubricate everyday with SAE 20 oil. A few drops applied on eachside of each nut.

Lead Screw Bearings: Lubricate the bearingslocated at the ends of the table and just in front ofthe Y axis hand crank. You will find oil ports witha ball stopper. Lubricate daily. Apply smallamount of SAE 20 using an oil can with a pointednozzle to help push in the ball.

General

Most of the bearings are factory-sealed. A sealedbearing requires no lubrication during its lifetime.Should a bearing fail, your mill will probablydevelop a noticeable rumble, which will increasewhen the machine is put under load. If allowed toget worse, overheating of the journal containingthe bad bearing could occur. If the bad bearing isnot replaced, it will eventually seize – possiblydoing damage to other parts of the machine.Bearings are standard sizes and can be replacedthrough Grizzly.

Quill bearings are under a lot of pressure (pre-loading). If not maintained properly, they will wearout prematurely. You will need to partially dis-mantle the machine once a year to repack thebearings. Please call the service department forinstructions about repacking your quill bearings.
