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 electrician or qualified service personnel in accordance with all applicable codes and standards.

or equipment damage may occur if machine is not properly grounded and connected to 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 specified circuit requirements.

For your own safety and protection of

Note: Circuit requirements in this manual apply to

a dedicated circuit—where only one machine will be running on the circuit at a time. If machine will be connected to a shared circuit where multiple machines may be running at the same time, consult an electrician or qualified service personnel to ensure 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.)

Lag shield anchors with lag screws (see below) are a popular way to anchor machinery to a concrete floor, because the anchors sit flush with the floor surface, making it easy to unbolt and move the machine later, if needed. However, anytime local codes apply, you MUST follow the anchoring methodology specified by the code.

Anchoring machinery to the floor prevents tipping or shifting and reduces vibration that may occur during operation, resulting in a machine that runs slightly quieter and feels more solid.

If the machine will be installed in a commercial or workplace setting, or if it is permanently connected (hardwired) to the power supply, local codes may require that it be anchored to the floor.

If not required by any local codes, fastening the machine to the floor is an optional step. If you choose not to do this with your machine, we recommend placing it on machine mounts, as these provide an easy method for leveling and they have vibration-absorbing pads.

Note: For permanent floor mounting, refer to

Anchoring to Floor on Page 16.

This machine creates a lot of wood chips/ dust during operation. Breathing airborne dust on a regular basis can result in permanent respiratory illness. Reduce your risk by wearing a respirator and capturing the dust with a dust-collection system.

Minimum CFM at Dust Port: 400 CFM

Do not confuse this CFM recommendation with the rating of the dust collector. To determine the CFM at the dust port, you must consider these variables: (1) CFM rating of the dust collector, (2) hose type and length between the dust collector and the machine, (3) number of branches or wyes, and (4) amount of other open lines throughout the system. Explaining how to calculate these variables is beyond the scope of this manual. Consult an expert or purchase a good dust collection "how-to" book.

To connect dust collection system to machine:

4. Uses work table feed handle and handwheel to align workpiece measurements with bit.

5. Secures workpiece to work table with holddown clamp assembly.

6. Puts on safety glasses or face shield and respirator.

7. Inspects bit spiral, selects appropriate chuck rotation direction, and turns machine ON.

IMPORTANT: Ensure bit rotates so it pulls

out chips during operation.

CAUTION: Avoid plunging or mortising deep-

er than the spiral of the bid is designed. Avoid mortising holes deeper than 4 times the diameter of the bit. Whip can occur.

8. If using an end mill or performing a sidecutting operation, uses conventional milling method and moves workpiece against rotation of the bit. DO NOT use climb-milling method.

Model G0846 (Mfd. Since 02/18)

9. Uses work table feed handle to slowly move workpiece into bit, bores hole, then moves workpiece away from bit.

10. Limits depth of each cutting pass to

⁄16" or

less.

11. Turns machine OFF when operations are complete.

• When mortising through hard spots in wood, use shorter bits with 4-flute design so small bites can be made and bit is less likely to grab hard spots as 2-flute bits can do.

• Avoid deep cuts with bits where spirals become buried or partially buried in workpiece and cannot expel shavings. When mortising,

limit cutting depth to

⁄16" per pass.

12. Unclamps and removes workpiece only after chuck has come to a complete stop.

Operating Tips

Cutting tools are sharp and can easily cause laceration injuries. Always protect your hands with leather gloves or shop rags when handling cutting tools.

Here are a few things you can do to ensure easy operation and better workpiece results:

• Use the correct bit for the job. Adjust the chuck rotation so the bit pulls out chips during the boring operation.

• Never rush a drilling or mortising procedure. Extra care during setup will ensure satisfactory results.

Changing Bits

The Westcott-style 5⁄8" chuck included with the Model G0846 is designed to work best with shank slot mortising bits (see Figure 15). DO NOT install or use vertical mortiser chisel bits.

⁄8"

• When using bits of different profiles and design, take time to understand what makes them different and how your process or technique may have to change.

• Use bits with a

⁄8" shank for safe, consistent results during operation. Bits with smallerdiameter shanks have an increased risk of breaking or coming loose during boring operations, which may result in injury.

• To use bits with a

⁄4" shank, use the T28358 Westcott-style chuck (refer to Accessories on Page 26).

• For longer or deeper mortises, 4-flute bits are recommended for smaller chip size and faster chip removal.

power before adjustments, maintenance, or service.

Schedule

For optimum performance from this machine, this maintenance schedule must be strictly followed.

Ongoing

To maintain a low risk of injury and proper machine operation, if you ever observe any of the items below, shut down the machine immediately and fix the problem before continuing operations:

• Vibration.

• Loose mounting bolts.

• Damaged chuck or bit.

• Worn or damaged wires.

• Any other unsafe condition.

Weekly/Monthly Maintenance (as required based on workload and operating environment)

• Clean/vacuum wood chips and sawdust off of motor, and out of chuck jaws.

Cleaning the Model G0846 is relatively easy. Vacuum excess wood chips and sawdust, and wipe off the remaining dust with a dry cloth. If any resin has built up, use mineral spirits to remove it, then when dry apply a light coat of oil.

Protect the unpainted cast-iron work table by wiping it clean after every use—this ensures moisture from wood dust does not remain on bare metal surfaces. Keep the table rust-free with regular applications of products like SLIPIT 26 for more details).

(see Page

Bit Care

A horizontal boring machine bit requires proper care.

• Store the bits so their sharp points and flutes are protected. A wooden or plastic box that keeps bits from touching one another works best.

• Keep bits clean and rust free.

• Lubricate work table handle points, holddown clamp, chuck jaws, work table elevation ways, work table leadscrew, and work table roller bearing tracks (refer to Lubrication on Page 28).

Model G0846 (Mfd. Since 02/18)

• Store lightly oiled.

• Have bits sharpened as soon as they show any signs of dulling.

locations.

If the gib is too loose, the quality of boring operations will suffer because the table will have loose, sloppy movement against the dovetails. If the gib is too tight, it will be difficult to raise and lower the table.

The goal of adjusting the gib is to keep the vertical movement of the table snug, without excessive looseness or binding.

Wiring Safety Instructions

SHOCK HAZARD. Working on wiring that is con-

nected to a power source is extremely dangerous. Touching electrified parts will result in personal injury including but not limited to severe burns, electrocution, or death. Disconnect the power from the machine before servicing electrical components!

MODIFICATIONS. Modifying the wiring beyond what is shown in the diagram may lead to unpredictable results, including serious injury or fire. This includes the installation of unapproved aftermarket parts.

WIRE CONNECTIONS. All connections must be tight to prevent wires from loosening during machine operation. Double-check all wires disconnected or connected during any wiring task to ensure tight connections.

CIRCUIT REQUIREMENTS. You MUST follow the requirements at the beginning of this manual when connecting your machine to a power source.

WIRE/COMPONENT DAMAGE. Damaged wires or components increase the risk of serious personal injury, fire, or machine damage. If you notice that any wires or components are damaged while performing a wiring task, replace those wires or components.

MOTOR WIRING. The motor wiring shown in these diagrams is current at the time of printing but may not match your machine. If you find this to be the case, use the wiring diagram inside the motor junction box.

CAPACITORS/INVERTERS. Some capacitors and power inverters store an electrical charge for up to 10 minutes after being disconnected from the power source. To reduce the risk of being shocked, wait at least this long before working on capacitors.

EXPERIENCING DIFFICULTIES. If you are experiencing difficulties understanding the information included in this section, contact our Technical Support at (570) 546-9663.
