Additional Safety for Mill/Drills
UNDERSTANDING CONTROLS. Make sure you
understand the use and operation of all controls.
SAFETY ACCESSORIES. Always use a chip guard in addition to your safety glasses when mill­ing/drilling to prevent bodily injury.
WORK HOLDING. Before starting the machine, be certain the workpiece has been properly clamped to the table. NEVER hold the workpiece by hand when using the mill/drill.
CHUCK KEY SAFETY. Always remove your chuck key, drawbar wrench, and any service tools immediately after use.
SPINDLE SPEEDS. Select the spindle speed that is appropriate for the type of work and mate­rial. Allow the mill/drill to gain full speed before beginning a cut.
POWER DISRUPTION. In the event of a local power outage during use of the mill, drill turn OFF all switches to avoid possible sudden start up once power is restored.
SPINDLE DIRECTION CHANGES. Never reverse spindle direction while the spindle is turning.
MACHINE CARE AND MAINTENANCE. Never operate the mill/drill with damaged or worn parts. Maintain your mill/drill in proper working condition. Perform routine inspections and maintenance promptly. Put away adjustment tools after use.
STOPPING SPINDLE. DO NOT stop the mill/drill using your hand against the chuck.
BE ATTENTIVE. DO NOT leave the mill/drill run­ning unattended for any reason.
DISCONNECT POWER. Make sure the mill/drill is turned OFF, disconnected from its power source and all moving parts have come to a complete stop before starting any inspection, adjustment, or maintenance procedure.
AVOIDING ENTANGLEMENT. Keep loose cloth­ing articles such as sleeves, belts or jewelry items away from the spindle. Never wear gloves when operating the mill/drill.
TOOL HOLDING. Always use the proper tools for the material you are machining. Make sure they are held firmly in the proper tool holder for the job.
CL EA N - U P. DO NOT clear chips by hand. Use a brush, and never clear chips while the spindle is turning.
CUTTING TOOL INSPECTION. Inspect drills and end mills for sharpness, chips, or cracks before each use. Replace dull, chipped, or cracked cut­ting tools immediately. Handle new cutting tools with care. Leading edges are very sharp and can cause lacerations.
EXPERIENCING DIFFICULTIES. If at any time you are experiencing difficulties performing the intended operation, stop using the machine! Contact our Technical Support at (570) 546-
9663.

SECTION 2: POWER SUPPLY
Before installing the machine, consider the avail­ability and proximity of the required power supply circuit. If an existing circuit does not meet the requirements for this machine, a new circuit must be installed. To minimize the risk of electrocution, fire, or equipment damage, installation work and electrical wiring must be done by an electrican or qualified service personnel in accordance with all applicable codes and standards.
Electrocution, fire, or equipment damage may occur if machine is not correctly grounded and connected to the power
The full-load current rating is the amperage a machine draws at 100% of the rated output power. On machines with multiple motors, this is the amperage drawn by the largest motor or sum of all motors and electrical devices that might operate at one time during normal operations.
The full-load current is not the maximum amount of amps that the machine will draw. If the machine is overloaded, it will draw additional amps beyond the full-load rating.
If the machine is overloaded for a sufficient length of time, damage, overheating, or fire may result— especially if connected to an undersized circuit. To reduce the risk of these hazards, avoid over­loading the machine during operation and make sure it is connected to a power supply circuit that meets the requirements in the following section.
For your own safety and protection of
Note: The circuit requirements listed in this man­ual apply to a dedicated circuit—where only one machine will be running at a time. If this machine will be connected to a shared circuit where mul­tiple machines will be running at the same time, consult a qualified electrician to ensure that the circuit is properly sized for safe operation.
A power supply circuit includes all electrical equipment between the breaker box or fuse panel in the building and the machine. The power sup­ply circuit used for this machine must be sized to safely handle the full-load current drawn from the machine for an extended period of time. (If this machine is connected to a circuit protected by fuses, use a time delay fuse marked D.)
This machine is prewired to operate on a 110V power supply circuit that has a verified ground and meets the following requirements:

Improper connection of the equipment-grounding wire can result in a risk of electric shock. The wire with green insulation (with or without yellow stripes) is the equipment-grounding wire. If repair or replacement of the power cord or plug is nec­essary, do not connect the equipment-grounding wire to a live (current carrying) terminal.
Check with a qualified electrician or service per­sonnel if you do not understand these grounding requirements, or if you are in doubt about whether the tool is properly grounded.

Site Considerations
Weight Load
Physical Environment
Place this machine near an existing power source.
Shadows, glare, or strobe effects that may distract
Refer to the Machine Data Sheet for the weight of your machine. Make sure that the surface upon which the machine is placed will bear the weight of the machine, additional equipment that may be installed on the machine, and the heaviest work­piece that will be used. Additionally, consider the weight of the operator and any dynamic loading that may occur when operating the machine.
Space Allocation
Consider the largest size of workpiece that will be processed through this machine and provide enough space around the machine for adequate operator material handling or the installation of auxiliary equipment. With permanent installations, leave enough space around the machine to open or remove doors/covers as required by the main­tenance and service described in this manual.
See below for required space allocation.
Children or untrained people may be seriously injured by this machine. Only install in an access restricted location.
The physical environment where the machine is operated is important for safe operation and lon­gevity of machine components. For best results, operate this machine in a dry environment that is free from excessive moisture, hazardous chemi­cals, airborne abrasives, or extreme conditions. Extreme conditions for this type of machinery are generally those where the ambient temperature range exceeds 41°–104°F; the relative humidity range exceeds 20–95% (non-condensing); or the environment is subject to vibration, shocks, or bumps.
Electrical Installation
Make sure all power cords are protected from traffic, material handling, moisture, chemicals, or other hazards. Make sure to leave access to a means of disconnecting the power source or engaging a lockout/tagout device, if required.
Lighting
Lighting around the machine must be adequate enough that operations can be performed safely.
or impede the operator must be eliminated.

5. Unbolt the machine from the pallet, then with
an assistant steadying the machine to pre­vent it from swinging, lift it slightly off of the pallet. Use the cross handwheel to move the table forward or backward as necessary to balance the machine so it hangs as close to level as possible.
The Model G0704 is a heavy machine. Serious personal injury may occur if safe moving methods are not used. To be safe, get assistance and use power equipment to move the shipping crate and remove the machine from the crate.
To remove your machine from the shipping crate and place it in position:
1. Place the crate adjacent to the location where
your machine will be placed, then remove the shipping crate from the pallet.
2. Position the stand into the desired location.
3. Use the vertical handwheel to raise the head-
stock as far as possible.
6. Lift the machine and carefully place it onto the stand.
7. Bolt the machine to the stand with the four M10-1.25 x 50 hex bolts and flat washers.
—If you are placing the machine on a work-
bench, it must be securely mounted to the workbench surface.
The strongest mounting option is a "Through
Mount" where holes are drilled all the way through the workbench, and hex bolts, wash­ers, and hex nuts are used to secure the machine to the workbench.

Mounting to Shop
Floor
Although not required, we recommend that you mount your new machine cabinet to the floor. Because this is an optional step and floor mate­rials may vary, floor mounting hardware is not included. Generally, you can either bolt the cabi­net to the floor or mount it on machine mounts. Both options are described below. Whichever option you choose, it is necessary to level the cabinet with a precision level.
Bolting to Concrete Floors
Lag shield anchors with lag bolts and anchor studs (Figure 10) are two popular methods for anchoring an object to a concrete floor. We sug­gest you research the many options and methods for mounting your machine and choose the best that fits your specific application.
Using Machine Mounts
Using machine mounts, shown in Figure 11, gives the advantage of fast leveling and vibration reduc­tion. The large size of the foot pads distributes the weight of the machine to reduce strain on the floor.
Figure 11. Machine mount example.
Figure 10. Typical fasteners for mounting to
concrete floors.
NOTICE
Anchor studs are stronger and more per­manent alternatives to lag shield anchors; however, they will stick out of the floor, which may cause a tripping hazard if you decide to move your machine.
NOTICE
We strongly recommend securing your machine to the floor if it is hardwired to the power source. Consult with your electrician to ensure compliance with local codes.

Handle
Figure 12. Elevation handwheel handle.
Your machine includes an B-16 drill chuck arbor and drill chuck. Before use, the drill chuck must be installed onto the arbor. The This drill chuck installation is intended to be semi-permanent.
Tip: For a permanent installation, chill the arbor in the freezer for 15 minutes before performing the following procedure. The taper will expand as it returns to room temperature, permanently locking the chuck.
To install the drill chuck onto the arbor:
1. Clean the grease off the drill chuck and all
taper mating surfaces. Pay particular atten­tion to the B-16 bore in the drill chuck—it must be free from all grease, oil, and debris.
2. Retract the drill chuck jaws fully by turning the body of the drill chuck counterclockwise.
3. Insert the arbor into the drill chuck. Tap the arbor lightly with a brass or other soft-headed hammer to get a good fit.
2. Use the same method to install the three small handwheel handles to the three table travel handwheels (Figure 13).
Figure 13. Table handwheel handles.
Note: While it may not seem like there is
anything keeping the drill chuck in place, the B-16 Taper fit provides a strong bond and will hold the drill chuck tightly (Figure 14).

Calculating Spindle
Speed
Closely follow the proper spindle speed and proper feed rate to produce good results, reduce undue strain on all moving parts and increase operator safety.
Prior to milling, determine the spindle speed needed to cut your workpiece, then set the speed on the machine.
To determine the needed spindle speed:
1. Use the table in Figure 24 to determine the
cutting speed required for the material of your workpiece.
2. Measure the diameter of your cutting tool in inches.

Model G0704 (Mfg. Since 0 8/11)
Spindle Speed and
Direction
Setting the speed on the Model G0704 is a two part process. The gearbox in the headstock has two gear ranges and the motor is a variable speed unit. Together, these two systems provide an overall speed range of 50–2250 RPM.
When the dial is turned up all the way, the motor draws the full amperage level. When combined with a cutting load, the motor can overheat and become damaged. If high speeds are needed, put the speed range into high "H" then turn the vari­able speed dial down, away from the maximum position. If the maximum RPM is needed, reduce the cutting load as much as possible and mini­mize the operation time at these speeds.
To set the spindle speed:
Note: It may be necessary to rotate the
spindle by hand to get the gears to mesh properly.
3. Make sure the work area is clear and that all safety precautions are taken.
4. Turn the variable spindle speed knob to the far left (slowest) position, then press the green start button and use the spindle direc­tion selection knob to choose the direction of spindle travel and start spindle rotation (Figure 26).
RPM Readout
1. Determine the appropriate spindle speed for your operation. See Calculating Spindle
Speed on Page 26.
2. Select the appropriate speed range using
the speed range selector knob (Figure 25). "H" represents the high speed range, which is capable of spindle speeds from 100–2250 RPM. "L" represents the low range, which is capable of spindle speeds from 50–1125 RPM.
Note: To maximize spindle torque, use the
low range.

Note: Do not overtighten the drawbar.
Overtightening makes arbor removal difficult and will damage the arbor and threads.
6. Re-install the drawbar cap.
5. Hold the chuck with one hand and finish loos-
ening the drawbar until the chuck falls out of the spindle.
Note: The chuck is attached to the arbor
using a B-16 taper. This attachment is con­sidered to be semi-permanent. There should be no need to remove the chuck from the arbor.

Loading Tooling
To remove the collet:
1. DISCONNECT MILL/DRILL FROM POWER!
Your Model G0704 features an R-8 spindle taper, which gives the freedom to use standard R-8 cutting tools and collets. These optional collets come in many sizes, typically ranging from
7
⁄8" and 3mm to 20mm, and should be matched to
your cutting tool shank size.
To install the tooling:
1. DISCONNECT MILL/DRILL FROM POWER!
2. Remove the drawbar cap.
3. Carefully clean the surface of the tooling and
spindle taper. Ensure that it is free of debris and is lightly oiled.
4. If you are using a cutting tool and collet, insert the cutting tool into the collet, then insert the collet up into the spindle taper, making sure the slot in the collet lines up with the pin in the spindle.

⁄16" to
2. Remove the drawbar cap.
3. Lock the quill in place with the quill lock
lever.
4. Use the included spindle pin to prevent the spindle from turning while you use an 8mm wrench to loosen the drawbar 2–3 turns. DO NOT continue loosening the drawbar without supporting the collet or it will fall from the spindle.
LACERATION HAZARD! Leading edges of end mills and other cutting tools can be very sharp. Protect your hands with gloves or a shop towel when handling.
If you are using a cutting tool that installs
directly into the spindle, insert the tool into the spindle taper, making sure the slot in the tool lines up with the pin in the spindle.
5. Slide the tooling upward until it makes con­tact with the drawbar threads.
6. Hand thread the drawbar into the tooling until the tooling draws up into the spindle taper.
7. Use the included spindle pin to prevent the spindle from turning while you use an 8mm wrench to tighten the drawbar.
Note: Do not overtighten the drawbar.
Overtightening makes collet removal difficult and will damage the drawbar threads, collet, and the spindle taper. Keep in mind that the taper keeps the collet and tool in place. The drawbar simply aids in seating the taper.
NOTICE
The Model G0704 drawbar will extract the arbor from the spindle. Once the arbor or collet has broken free from the spindle taper, be sure to properly support it while continuing to loosen the drawbar. Failure to properly support the arbor or collet while loosening the drawbar will result in the arbor or collet falling out of the spindle, causing damage to machine components.
5. Protect the table surface with a piece of
cardboard and hold the cutter/tool with a shop towel to prevent it from falling out of the collet. Continue loosening the drawbar until the collet is freed from the spindle.

Headstock Travel
(Z-Axis and Rotation)
To tilt the headstock to the left or right:
1. DISCONNECT MILL/DRILL FROM POWER.
Headstock height is adjustable in the vertical Z-axis to accept large workpieces. For unique milling operations, the headstock can be tilted right or left between 0° and 90°.
To raise or lower the headstock:
1. Unlock the vertical travel lock levers shown in Figure 30.

Table Travel
The mill/drill table can be moved in the longitudi­nal (X-axis) and cross (Y-axis) directions.
Longitudinal Feed
The X-axis is moved by the handwheels shown in Figure 32 at the end of the table. These handwheels will move the table in both directions side-to-side. One complete revolution of either handwheel moves the longitudinal feed 0.100". There is also a scale on the front of the table for use when a tight tolerance is not required. The longitudinal feed can be locked in position by table locks located on the front of the table (see Figure 33).

Gibs
To adjust the headstock gibs:
1. DISCONNECT MILL/DRILL FROM POWER!
Gibs are wedge-shaped pieces of metal that fill the gap between the sliding surfaces of the machine. By adjusting the position of the gib in its gap, you can remove any play that might exist between the adjacent components. The gibs are pre-adjusted at the factory but due to storage, break-in, and usage, may require adjustment. If movement seems too tight at first, make sure that all the rust preventative that was shipped on the machine is removed from the ways. Lubricate the ways with oil, and work the table back-and-forth several times until the movement is easier.
To adjust the table gibs:
1. DISCONNECT MILL/DRILL FROM POWER!
2. Loosen the table travel locks (Figure 55).

Leadscrew Backlash
When you turn the handwheels to adjust the posi­tion of the table, you will notice slight play (back­lash) in the handwheel before the table begins to move. If this play is greater than 0.008" (measured with the dial at the base of each handwheel), then you will need to adjust the leadscrew nuts.
To adjust the Y-axis leadscrew nut:
1. Locate the leadscrew nut underneath the
table through the hole in the base under the rubber way cover.
2. Tighten the adjustment screws on the leadscrew nut in the same manner as described for the X-axis leadscrew adjust­ment.
To reach the adjustment screws on the leadscrew nut, you may have to fabricate extensions for your hex wrenches. When adjusting, make adjust­ments in small increments. Attempting to reduce backlash to less than 0.003" is impractical and will add unnecessary wear to both the leadscrews and the leadscrew nuts.
To adjust the X-axis leadscrew:
1. Locate the X-axis leadscrew nut under the
middle of the table. The head on the adjust­ment screws face to the right (Figure 57).
Location of
Adjustment Screws
3. Test the adjustment by turning one of the cross handwheels. The ideal amount of play when properly adjusted is 0.003"–0.006".
Digital Readout Unit
Battery Replacement
If the digital readout unit stops functioning, the battery must be replaced.
To replace the digital readout unit battery:
1. Use a wide (#3) standard screwdriver or the
edge of a coin to remove the battery cover (Figure 58).
Figure 57. X-axis leadscrew adjusters.
2. Tighten the adjustment screws.
3. Test the adjustment by turning one of the

Motor Service
The bearings inside the motor are shielded and lubricated for the life of the bearing and require no routine maintenance.
This motor is equipped with long life carbon brushes. Brush life expectancy is affected by motor loading. Heavy motor loading will result in reduced brush life. If you notice a loss in power or if the motor becomes excessively noisy, inspect the brushes. If the brushes are worn down to (6mm) or less, it is time to replace them. When checking brushes, be sure to return each brush to the same hole in the same direction that it came from. When replacing old brushes, replace both brushes at the same time.
