110V Operation
The motor supplied with the G1004/G1008 is a dual-voltage 110/120V or 220/240V motor. (For information on operating at 220V, see the section following entitled 220V Operation.) Under normal use, the motor draws approximately 16 amps @ 110V, therefore it should be connected to a circuit that is protected by a 20 amp fuse or circuit breaker. This should be satisfactory for normal use, while providing enough protection against motor damage caused by power surges. Grizzly recommends that the circuit you use should be dedicated, (i.e., the G1004 or G1008 should pro­vide the only draw from that circuit). If frequent circuit failures occur when using the milling machine, contact our service department or your local electrical contractor. You are cautioned that equipment returned to us for service that shows evidence of being over-fused will be repaired or replaced totally at the customer’s expense, regardless of the present warranty status.
It is also necessary to connect a cord and plug to the machine. Be sure that both the plug and cord are rated at 20 amps and must include a ground­ing wire. See Figure 1.
SECTION 2: CIRCUIT REQUIREMENTS
Grounding
In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This tool must be equipped with an elec­tric cord having an equipment-grounding conduc­tor which must be properly connected to a grounding plug. The plug must be plugged into a matching outlet that is properly installed and grounded in accordance with all local codes and ordinances.
Figure 1. Grounded plug configuration.
If you find it necessary to use an extension cord with the Model G1004/G1008, make sure the ­cord is rated Hard Service (grade S) or better. Refer to the chart in the standard safety instruc­tions to determine the minimum gauge for the extension cord.
The extension cord must also contain a ground wire and plug pin. Always repair or replace exten­sion cords when they become worn.
Extension Cords
Potential for electrical shock hazard, this equipment must be grounded. Verify that
any existing electrical outlet and circuit you intend to plug into is actually grounded. If it is not, it will be necessary to run a separate 12 A.W.G. copper grounding wire from the outlet to a known ground. Under no circumstances should the grounding pin from any three­pronged plug be removed. Serious personal
injury may occur.

We have covered some basic electrical requirements for the safe operation of your Milling Machine. These requirements are not necessarily comprehensive. You must be sure that your particular electrical con­figuration complies with local and state codes. Ensure compliance by checking with your local municipality or a licensed electrician.
Potential for electrical shock hazard, this equipment must be grounded. Verify that
any existing electrical outlet and circuit you intend to plug into is actually grounded. Under no circumstances should the grounding pin from any three-pronged plug be removed.
Serious personal injury may occur.
220V Operation
The Model G1004/G1008 has a motor which can be operated on a 220V single phase circuit. In order to operate at 220V it is necessary to rewire the motor connections (refer to the wiring dia­grams at the back of this manual) and to add a 220V capable cord and plug. The style of plug you require will depend upon the type of service you currently have or plan to install. Figure 2 shows recommended plug styles.
The motor will safely draw about 8 amps at 220V under load, therefore it should be connected to a circuit that is protected by a 15 amp fuse or circuit breaker. This should be satisfactory for normal use, while providing enough protection against motor damage caused by power surges. Grizzly recommends that the circuit you use should be dedicated, (i.e., the G1004 or G1008 should pro­vide the only draw from that circuit). If frequent circuit failures occur when using the milling machine, contact our service department or your local electrical contractor. You are cautioned that equipment returned to us for service that shows evidence of being over-fused will be repaired or replaced totally at the customer’s expense, regardless of the present warranty status.
We do not recommend the use of extension cords on 220V equipment. It is much better to arrange the placement of your equipment and the installed wiring to eliminate the need for exten­sion cords. Should it be necessary to use an extension make sure the cord is rated Hard Service (grade S) or better.

Clean Up
The unpainted surfaces are coated with a waxy oil to protect them from corrosion during ship­ment. Remove this protective coating with a sol­vent cleaner or citrus-based degreaser. Avoid chlorine-based solvents as they may damage painted surfaces should they come in contact. Always follow the usage instructions on the prod­uct you choose for clean up.
Do not use gasoline or other petroleum­based solvents to remove this protective coating. These products generally have low flash points which makes them extremely flammable. A risk of explosion and burning exists if these products are used. Serious personal injury may occur.
Site Considerations
FLOOR LOAD
Your G1004/G1008 Milling Machine represents a large weight load in a 28" x 20" footprint. Most commercial or garage shop floors should be suf­ficient to carry the weight. Before moving this milling machine onto a residential floor inspect it carefully to determine that it will be sufficient to carry the load. If you question the strength of your floor, you should consider having it inspected for possible reinforcement.
WORKING CLEARANCES
Working clearances can be thought of as the dis­tances between machines and obstacles that allow safe operation of every machine without limitation. Consider existing and anticipated machine needs, size of material to be processed through each machine, and space for auxiliary stands and/or work tables. Also consider the rel­ative position of each machine to one another for efficient material handling. Be sure to allow your­self sufficient room to safely run your machines in any foreseeable operation.
LIGHTING AND OUTLETS
Lighting should be bright enough to eliminate shadow and prevent eye strain. Electrical circuits should be dedicated or large enough to handle combined motor amp loads. Outlets should be located near each machine so power or exten­sion cords are not obstructing high-traffic areas. Be sure to observe local electrical codes for prop­er installation of new lighting, outlets, or circuits.
Make your shop “child safe”. Ensure that your workplace is inaccessible to young­sters by closing and locking all entrances when you are away. Never allow visitors in your shop when assembling, adjusting or operating equipment.
All die-cut metal parts have a sharp edge (called “flashing”) on them after they are formed. This is generally removed at the factory. Sometimes a bit of flashing might escape inspection, and the sharp edge may cause cuts or lacerations when handled. Please examine the edges of all die-cut metal parts and file or sand the edge to remove the flashing before handling.
Many of the solvents commonly used to clean machinery can be highly flammable, and toxic when inhaled or ingested. Always work in well-ventilated areas far from potential ignition sources when dealing with solvents. Use care when disposing of waste rags and towels to be sure they do not create fire or environmental hazards. Keep children and animals safely away when cleaning and assembling this machine.

Assembly of the G1004/G1008 is straightforward. We have organized the assembly process into steps. Please follow them in sequence.
ORDER OF ASSEMBLY
A. Leveling B. Mounting Handles C. Install Collet or Arbor D. Fly Cutter E. Knee Hand Crank
Tools Required: A complete set of metric Allen
®
wrenches will be necessary for most of the assembly and adjustments. A rubber mallet and a set of open ended, metric wrenches will also be needed.
Before attempting to use your mill, make sure that it is sitting firmly in place and that the work table is level. Should you find that the machine rocks or is not level, use mild steel shim stock or leveling pads, such as those sold by Grizzly Industrial (G7159).
Disconnect the power before changing col­lets or arbors on the G1004/G1008. Serious personal injury may occur.
SECTION 4: ASSEMBLY
Collet or Arbor
Installation
Three handles are supplied with the G1004/G1008. They are black and have a slotted head screw through them. On the threaded por­tion is a nut. Tighten the nut so that the black han­dle does not spin. Screw the handles into the handwheels until they are tight. Loosen them one full turn. While maintaining the orientation of the slotted screw, turn the nut so that it now tightens against the handwheel.

The Models G1004/08 feature an R-8 spindle which accepts many industrial collets and arbors.
To install a collet or an arbor:
1. Release the latches on the head lid and
open it.
2. Determine the location of the pin inside the
spindle.
3. Align the keyway of the collet to the side
where you found the pin and insert the col­let or cutting tool’s arbor up into the spindle housing. Rotate the collet slightly to line up the keyway with the pin in the spindle bore.
Page 12
-12-G1004/1008 Vertical Milling Machine
4. Turn the hex head at the top of the drawbar
(located on the top, front of the head) clock­wise until the threads at the bottom of the drawbar mesh with the female threads in the top of the collet or arbor.
5. When using a collet: Insert the cutter in the
hole at the bottom of the collet and contin­ue to tighten the drawbar until both the col­let and cutter are tightly in place. Do not
over-tighten the collet. Grasp the rim of the front pulley. Hold it tight while tight­ening 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 soft
faced mallet to loosen the collet from the spindle. Hold the collet/cutter with a
shop towel from the bottom to prevent it from dropping completely out of the machine.
3. Continue to turn the drawbar counterclock-
wise until it is free from the collet. Once loose, remove and replace with your desired collet. Remove cutting tools from
spindle when not in use.
Your mill comes equipped with a fly cutter that fits on the 1" stub end of the R-8 arbor (this comes installed in the spindle).
To install the fly cutter:
1. Clean any accumulated grease, oil, or
debris off of the R-8 arbor.
2. Fit the fly cutter onto the stub end of the
arbor so the keys on the arbor and the key­ways on the fly cutter come together.
3. Secure the fly cutter to the arbor with the
cap screw and washer provided. Tighten with an 8mm Allen
®
wrench.
4. Install the arbor with fly cutter into the mill
as described under the heading “Collet or Arbor Installation.”
The Knee hand crank is located to the left of the Y-axis. It is shipped from the factory with the han­dle installed on the knee gear shaft backwards. To install properly begin by removing the exter­nal retaining ring on the end of the shaft. Slide the handle off of the shaft and re-install so that the handle faces outward.

Graduated Dials
SECTION 6: ADJUSTMENTS
The graduated dials on the handwheels for the table and fine feed can be indexed or “zeroed” to help make accurate and convenient movements. Each dial can be reset or locked with the setscrew or thumb screw provided.
Example:
Suppose you want to drill a series of holes in a workpiece at 0.625" centers. After locating the first hole’s placement and drilling, you can set the dial of the appropri­ate axis to zero and move the table 0.625". Drill the next hole and proceed as above.
3. Loosen the setscrew on the knurled surface
of the handwheel dial. Turn the dial until the “0” lines up with the index line. Tighten the setscrew.
4. Turn the handwheel according to the dis-
tance you want to move downward. Each complete revolution equals 0.100".
Locking:
For milling operations, the spindle height can be locked in by tightening the black lever on the forward, right hand portion of the head.
You have two options for spindle height adjust­ment: a drill press style, levered downfeed and a micro adjustment handwheel. The lever is located on the right, forward portion of the head. The micro adjustment handwheel is to the left.
To operate the feed lever:
Pull the lever toward you. The spindle will go down until you stop pulling or until it hits the depth stop.
To operate the micro-adjustment handwheel:
1. Tighten the knurled locking knob located on
the left side of the headstock and just behind the fine downfeed handwheel.
2. Locking out the levered downfeed will
transfer control to the handwheel. The handwheel will not function if the knurled locking knob is loose.
Spindle Height
To calibrate the depth stop:
1. Roll the quill down using the lever handle
until you reach the desired depth shown on the scale. Lock the quill with the lever lock handle. Turn the depth stop nut until it meets the bottom of the depth stop block. Tighten the jam nut against the bottom of the stop nut.
2. Roll the spindle up into the head. Place a
piece of paper on the workpiece. Loosen the knee lock handle and raise the knee until the drill bit or cutter just touches the paper. Tighten the knee lock.
3. Begin drilling or milling. Note for precision
depth: set the depth stop shallow of the desired depth by
1
16''. Drill the hole and measure. Finish to depth using the fine downfeed handwheel with its graduated dial and use the procedure laid out in the section above titled: Graduated Dials.

Your Model G1004/G1008 milling machine requires very little maintenance. A thorough cleaning, now and again, will increase the machine’s durability and efficiency by removing chips and grime that can gum up moving parts.
An occasional application of a protective spray coating will keep the table and other bare metal parts from rusting and pitting.
REMEMBER: When performing maintenance or repairs on shop equipment, always disconnect the machine from its power supply.
The G1004/1008 milling machine table features tapered gibs in the dovetail ways. To tighten the table, loosen the screw at the small end of the tapered gib and tighten the screw at the large end. Use the same procedure for the saddle and knee gib adjustments.
Spindle: Add oil to the oil cup after every 4 hours of use. The cup is located on the right portion of the milling head just under the belt guard. SAE 20 oil is recommended.
One Shot Lubricator: Located on the left side of the knee. Check periodically and fill oil reservoir as necessary with SAE 20. This lubricator will supply oil to the knee, apron and table slides. By pulling the lever you will apply enough oil for a 4 hour period of use.
Flood Coolant System: For best results it is rec­ommended that a water soluble oil be used. Replace coolant when it becomes noticeably con­taminated or rancid. Take the time to clean the sludge from the bottom of the tank annually. Access to the tank may be made from the right or left panels on the stand/base.
Table and Apron Lead Screws: Lubricate every day with SAE 20 oil. A few drops applied on each side of each nut.
Lead Screw Bearings: Lubricate the bearings located at the ends of the table and just in front of the Y axis hand crank. You will find oil ports with a ball stopper. Lubricate daily. Apply small amount of SAE 20 using an oil can with a pointed nozzle to help push in the ball.
General
Most of the bearings are factory-sealed. A sealed bearing requires no lubrication during its lifetime. Should a bearing fail, your mill will probably develop a noticeable rumble, which will increase when the machine is put under load. If allowed to get worse, overheating of the journal containing the bad bearing could occur. If the bad bearing is not replaced, it will eventually seize – possibly doing damage to other parts of the machine. Bearings are standard sizes and can be replaced through Grizzly.
Quill bearings are under a lot of pressure (pre­loading). If not maintained properly, they will wear out prematurely. You will need to partially dis­mantle the machine once a year to repack the bearings. Please call the service department for instructions about repacking your quill bearings.
