Glossary Of Terms

The following is a list of common definitions, terms and phrases used throughout this manual as they relate to this CNC router and woodworking in general. Become familiar with these terms for assembling, adjusting or operating this machine. Your safety is VERY important to us at Grizzly!

Axis: Direction of movement. On a three-axis mill-

ing machine, axes are typically X (left-right), Y (front-back) & Z (up-down). Axis directions are described as positive or negative. On this machine, negative movement is defined as movement towards the front (Y), left (X), and bottom (Z) of the working envelope.

Ball End (Ball Nose): A cutting tool that has a

rounded cutting arc, where the arc diameter is equal to the cutting diameter.

Ball Screw: Drive system component. The ball

screw is rotated by the stepper motor and provides the means for moving the gantry and spindle along the axes.

Bed: The bed of the CNC consists of a welded

steel frame, an extruded aluminum table top, and a tongue-and-groove table top with integrated T-slots.

CAD: Computer aided design. CAD software is

used to create a digital model of a project.

Compression Bit: A cutting tool with a combi-

nation of up and down shear cutting edges. Typically used for cutting laminate material to prevent tear-out on both sides of the sheet.

Conventional Cut: Cut that occurs when the

rotation of the cutter moves in opposite direction as the workpiece.

Down-Cut Bit: A cutting tool with edges that

carve downward on the face of the toolpath. Reduces the potential for tear-out, but requires a slower feed rate.

Dust Shoe: An accessory that channels dust and

debris directly from the cutting tool through an attached dust collection system.

End Mill: A cutting tool with a straight end, typi-

cally with spiral flute(s). It creates a channel with a flat bottom perpendicular to the sides.

Feed Rate: The speed at which the cutting tool

moves along a workpiece.

CAM: Computer aided manufacturing. CAM soft-

ware converts CAD models into a toolpath defined by G-code that CNC machines can interpret.

Chip Load: Chip load is the measure of the

thickness of chips a tool will cut. Chip load is equal to: Feed Rate ÷ (Spindle Speed X Number of Flutes).

Climb Cut: Cut that occurs when the rotation of

the cutter moves in same direction as the workpiece.

CNC: Computer numerical control. Manufacturing

controlled by a computer via coded instructions.

Collet: Metal collar that holds the cutting tool in

place within a spindle nut.

-6-

Finish Cut: A 3D toolpath that reduces or elimi-

nates the irregular contours left by a rough cut.

Flute Length: The length of the cutting portion on

a router bit or cutting tool.

Flutes: The cutting edges or inserts of a router bit

or cutting tool.

Form Bit: A bit that carves a standard profile such

as a roundover, ogee, or similar contour.

Gantry: The structure that straddles the bed and

carries the spindle. It moves the full length of the bed along the Y-axis.

G-Code: A machine language that uses axis

points and commands, which the machine uses to move and perform functions.

Model G0931 (Mfd. Since 02/21)

Hold-Down: A clamp used to firmly hold a

workpiece or fixture to the table.

Spindle Speed: Rotational speed of cutting tool

(RPM).

Home Position: A fixed point on the machine set

with proximity switches. It is the machine zero point on all axes.

Letter Address: The first letter of a G-code

command. Commands with similar functions are usually grouped within the same letter address. For example, the "G" letter address deals with preparatory functions that define the machine's operation, while the "M" letter address handles miscellaneous machine functions such as turning on spindles, pumps, and other auxiliary tasks.

Origin: User designated zero point for a workpiece

from which the router will reference the positioning of all cutting.

Plunge: The distance on the Z-axis that the

spindle and cutting tool moves toward, into, or along the workpiece.

Pocket Toolpath: A toolpath that creates a cavity

in the horizontal surface of a workpiece.

Post Processor: A software function that formats

G-code into a dialect understood by a specific machine.

Profile Toolpath: A toolpath that cuts along the

profile of a set of vectors. Typically used to cut out the shape of a design.

Spoilboard: Sacrificial material placed under the

workpiece that allows the cutting tool to go past the workpiece to ensure a full, clean cut without damaging the work table. Usually made of MDF.

Stepper Motor: DC motor that moves in precise

steps when pulses are received. Has very accurate positioning and speed control.

Surfacing: The process of leveling the surface of

a workpiece or spoilboard so it is perpendicular to the spindle.

Tool Deflection: Tool deflection occurs when the

spindle speed and feed rate exert sufficient force to deflect the cutting tool. Deflection leads to excessive wear and chatter, which can shorten tool life and leave unwanted tooling marks on the material.

Tool Setter: A device used to set the zero point

(origin) for the Z-axis.

Toolpath: User defined route that the cutter fol-

lows to machine a workpiece.

Up-Cut Bit: A cutting tool with edges that carve

upward on the face of the toolpath. This removes chips from the material, but can pull the material off the bed and splinter the top edge.

Proximity Switch: A magnetic limit switch that is

used to find home position.

Rapid:

Rough Cut: A 3D toolpath where the initial cut is

Soft Limits: Axis limits imposed by the work space

Model G0931 (Mfd. Since 02/21)

The maximum speed of each axis. Higher

rapid rates decrease machining times.

designed to remove unwanted material, leaving a rough contour.

boundaries and based on controller settings and the location of home. An “out of soft limits error” implies that there is not enough room to move in a designated direction based on the positioning of the workpiece.

VFD: Variable frequency drive that controls the

speed (RPM) of the spindle. Enables the fine tuning of the spindle during the operation of a toolpath.

Working Envelope: The three-dimensional area

that the spindle can travel within while cutting or milling.

Additional Safety for CNC Routers

You can be seriously injured or killed by getting clothing, jewelry, or long hair entangled with rotating cutter/spindle. You can be severely cut or have fingers amputated from contact with rotating cutters. You can be blinded or struck by broken cutting tools, wood chips, improperly secured workpieces, or adjustment tools thrown from rotating spindle with great force. To reduce risk of serious injury when operating this machine, heed and understand the following:

UNDERSTAND ALL CONTROLS. Make sure

you understand the function and proper use of all controls before starting. This will help you avoid making mistakes that result in serious injury.

AVOIDING ENTANGLEMENT. DO NOT wear loose clothing, gloves, or jewelry, and tie back long hair. Keep all guards in place, secure, and properly operating. Always allow spindle to stop on its own. DO NOT stop spindle using your hand or any other object.

WEAR EYE PROTECTION. Always wear safety glasses. This provides protection for your eyes from wood chips or broken cutting tools.

USE CORRECT SPINDLE SPEED. Use proper speeds and feeds for each size and type of cutting tool as recommended by tool manufacturer. This helps avoid injury risk from tool breakage during operation and ensures best cutting results.

FIRE HAZARD. To reduce risk of fire, always use proper feeds and speeds for cutting tool and workpiece type. Avoid operations that dwell in one place. Be aware of signs of fire and keep fire extinguisher nearby. Chips and dust collection can disguise embers and smoke. Prepare a fire safety plan and ensure it is practiced by all operators. Never operate machine unattended unless workspace has a lights-out fire prevention system.

PROPERLY SECURE CUTTER. Firmly secure cutting tool so it does not fly out of spindle during operation.

PROPERLY COLLECT DUST. Only use dust collector to clear chips while spindle is turning. DO NOT clear chips by hand when cleaning. Only use a brush or shop vacuum when spindle/axes are NOT turning or moving.

SECURE WORKPIECE TO TABLE. Secure workpiece to table so workpiece cannot unexpectedly move or spin during operation. NEVER hold workpiece by hand during operation.

PROPERLY MAINTAIN MACHINE. Keep machine in proper working condition to help ensure that it functions safely and all guards and other components work as intended. Perform routine inspections and all required maintenance. Never operate machine with damaged or worn parts that can break or result in unexpected movement during operation.

DISCONNECT POWER FIRST. To reduce risk of electrocution or injury from unexpected startup, make sure CNC router is turned OFF, disconnected from power, and all moving parts are completely stopped before changing cutting tools or performing any inspection, adjustment, or maintenance procedure.

INSPECT CUTTING TOOL. Inspect cutting tools for sharpness, chips, or cracks before each use. Replace dull, chipped, or cracked cutting tools immediately. Do not use damaged tools as they are likely to break apart and could hit user with great speed and force.

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.

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.

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.)

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.

This machine is prewired to operate on a 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. If you ever notice that a cord or plug is damaged or worn, disconnect it from power, and immediately replace it with a new one.

We do not recommend using an extension cord with this machine. cord, only use it if absolutely necessary and only on a temporary basis.

Extension cords cause voltage drop, which can damage electrical components and shorten motor life. Voltage drop increases as the extension cord size gets longer and the gauge size gets smaller (higher gauge numbers indicate smaller sizes).

Any extension cord used with this machine must be in good condition and contain a ground wire and matching plug/receptacle. Additionally, it must meet the following size requirements:

Grounding Requirements

This machine MUST be grounded. In the event of certain malfunctions or breakdowns, grounding reduces the risk of electric shock by providing a path of least resistance for electric current.

This machine is equipped with a power cord that has an equipment-grounding wire and a grounding plug. Only insert plug into a matching receptacle (outlet) that is properly installed and grounded in accordance with all local codes and ordinances. DO NOT modify the provided plug!

2. Remove crate top and sides, small items

inside crate, and blocks on machine base.

Lift machine with forklift or hoist just enough

to clear pallet, then move pallet out of the way.

For accurate cutting results and to prevent warping, the table and frame MUST be leveled from side to side and from front to back on both ends. Re-check the table and frame 24 hours after installation, two weeks after that, and then annually to make sure they remain level.

Leveling machinery helps precision components remain straight and flat during the lifespan of the machine. Components on a machine that are not level may slowly twist due to the dynamic loads placed on the machine during operation.

To level machine:

Place level on table and align to either X- or

Y-axis.

Loosen top leveling foot hex nut and adjust

bottom fixed nut on threaded bolt (see Figure 10). Tighten hex nut against mounting leg to secure.

Note: Tighten fixed nut to raise machine, and

loosen fixed nut to lower machine.

Dust Collection

To connect dust collection system to machine:

Attach dust shoe bracket end to spindle

motor and secure with (1) M5-.8 x 45 cap screw and (1) M5-.8 hex nut (see Figure 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.

Workpiece Inspection

Some workpieces are not safe to cut or may require modification before they are safe to cut.

Before following:

Choosing Cutter

There are many cutters available. Be sure to choose the right one for your application and material. Read all manufacturer instructions before installing and using a cutter.

When choosing a cutter, consider:

• Material Type: This machine is intended for cutting natural and man-made wood products, laminate covered wood products, and some plastics. Cutting drywall or cementitious backer board creates extremely fine dust and may reduce the life of the bearings. This machine is NOT designed to cut metal, glass, stone, tile, etc.; cutting these materials with this machine may lead to injury.

• Foreign Objects: Nails, staples, dirt, rocks and other foreign objects are often embedded in wood. While cutting, these objects can become dislodged and hit the operator, or break the cutter, which might then fly apart. Always visually inspect your workpiece for these items. If they can't be removed, DO NOT cut the workpiece.

• Large/Loose Knots: Loose knots can become dislodged during the cutting operation. Large knots can cause machine damage. Choose workpieces that do not have large/loose knots or plan ahead to avoid cutting through them.

• Wet or "Green" Stock: Cutting wood with a moisture content over 20% causes unnecessary wear on the cutter and yields poor results.

• Excessive Warping: Workpieces with excessive cupping, bowing, or twisting are dangerous to cut because they are unstable and often unpredictable when being cut. DO NOT use workpieces with these characteristics!

Material Type: Most cutters are designed for

specific material. Choose a unique bit for plywood, engineered wood products, hardwood, and composite to improve overall results. If a general-purpose bit is needed, a two-flute, upcut, spiral bit is a good choice.

Application: Many design features are best

cut using specific tools. For example:

— Use a V-bit for cutting signs and lettering.

— Use a spoilboard cutter or fly cutter for sur-

facing a spoilboard or finishing a smooth, flat workpiece, such as a counter top.

— Use a form bit to cut a profile with a uni-

form contour, such as an ogee or round over.

— Use a chipbreaker or rougher for rough

cuts and quickly removing a large amount of material when the finish does not matter.

Feed and Speed Rates: Feed rate, spindle

speed, and number of flutes on the cutter determine chip load. The chip load affects the best diameter bit to use to get the highest quality finish while minimizing wear. Most manufacturers will list the recommended chip load for their cutters.

• Minor Warping: Workpieces with slight cupping can be safely supported if cupped side is facing table. On the contrary, a workpiece supported on the bowed side will rock during a cut and could cause severe injury.

-26-

Model G0931 (Mfd. Since 02/21)

4. Depth and Width of Cut: The cutter must be long enough to reach the maximum plunge depth of the operation and small enough to cut the details of the piece. However, shorter, wider bits will deflect less, leading to more accurate cuts, and they are less prone to wear and breakage.

Finish: If a high-quality finish is a priority, use

a cutter with more flutes. Four-flute cutters will be readily available in most cases. Don't forget that number of flutes is a component of calculating chip load.

Chip Displacement: Up-cut bits keep the

workpiece clear of chips, but on composite materials the upward force of the operation will chip and fray the top surface of the workpiece. Down-cut bits leave a smooth finish on the top of the workpiece, but pressing chips down creates more heat during the cut and frays the bottom of the workpiece on through cuts. Compression bits are fluted to cut up on the bottom, and down on the top, compressing the workpiece during a cutting operation. Compression bits are ideal for cutting materials like plywood and other composites.

Changing Cutter

Cutters are sharp! To reduce the risk of being cut, wear leather gloves when handling, installing, and removing cutters from spindle.

Clamp Plate

Wing Nut

Washer

Tighten wing nuts until workpiece is secure

and flat against table on all four sides/ corners.

Using a Spoilboard

A spoilboard should be used on top of the table with any operation the cutter cuts completely through the workpiece. Typically, a spoilboard is made of MDF that has been surfaced perfectly flat. Even a new piece of material should be surfaced before use.

Moisture will swell/warp MDF. Using a damp spoilboard may result in damaged or inaccurately cut workpieces, and damage to the machine. If liquid is spilled on spoilboard, it must be dried and resurfaced, or replaced.

2. Secure workpiece to spoilboard.

Note: Depending on the needs of the

workpiece and G-code, it could be appropriate to use additional hold-down clamps, double-sided tape, or mount the workpiece directly to the spoilboard with screws.

Surfacing Spoilboard

The G0931 can be used to surface a spoilboard or workpiece using the mill plane feature and an appropriate cutter (see Choosing Cutter on

Page 26).

Needed Qty

Items

Spoilboard Cutter or Fly Cutter ........................ 1

To surface using mill plane operation:

Hold down RUN/PAUSE on controller, then

press HIGH/LOW and release buttons together to open advanced processing menu.

2. Scroll to "Mill plane" and press OK.

— Depth defines the total depth of material

removed. Z Step defines how much material is removed per pass. For example, a Depth of 1 and Z Step of 0.25 would remove 1mm of material over four passes.

Press OK after all parameters have been

saved to start mill plane operation.

Adjusting Axis

Positions Manually

Knowing how to manually control axis movement is an essential part of operating the G0931. Axes must be positioned manually whenever a work origin is set.

Use axis movement buttons on controller (X+, X-, Y+, Y-, Z+, and Z-) to move axes. See Controller Functions on Page 5 for detailed button descriptions.

3. Choose "Scan mill" or "Encircle mill" and press OK. Operation parameters will appear.

Note: A "Scan mill" operation runs back and

forth from one end of the defined workpiece to the other. An "Encircle mill" operation runs from the outside to the inside of the defined workpiece.

Define operation parameters. Press RUN/

PAUSE to change a parameter and OK to save. Distances are measured in millimeters.

— Scan Type changes direction of operation.

For scan milling, "X Scan" runs back and forth across X-axis, and "Y Scan" runs back and forth across Y-axis. For encircle milling, "AC" runs counterclockwise around workpiece and "C" runs clockwise around workpiece.

— Height and Width defines size of area to

be surfaced.

Manual axis movement can be performed at two speeds and in three motion modes: Continuous, Step, and Distance.

Manual axis movement can move beyond soft limit proximity switches, which can damage the machine. Be aware of axis locations during manual movement, and be prepared to stop machine if axes move unexpectedly.

— Diameter defines diameter of surfacing

tool used.

Model G0931 (Mfd. Since 02/21)

Changing Axis Movement Speed

Press HIGH/LOW to toggle between fast and

slow speeds.

Changing Axis Movement Mode

1. Press MODE to toggle between Continuous,

Step, and Distance modes.

Setting Origin

Work origin is the workpiece-specific zero point, the starting point for the toolpath. All three axes need to be zeroed at the work origin before running code.

— In Continuous mode, press and hold axis

movement buttons to move axes. Release button to stop movement.

— In Step mode, press button to move axis

one step. Step size is determined by speed mode.

— In Distance mode, press button to move

axis a user-defined distance. Set distance by toggling to Distance mode, then input distance and press OK. Controller will display current setting.

Homing Axes

Homing the machine returns all three axes to "home" position or the machine-specific zero point. Home is determined by magnetic limit switches and will not change. Since all machine movement is calculated from home, always home axes and verify machine parameters before each operation.

To home axes:

The Z-axis can be set in relation to either the table surface or the workpiece surface, but it must correspond to what is established in the G-code. If this is not done properly, the cutter may crash into the material or the table, causing damage to the workpiece or the machine.

Set work origin before each unique operation. The work origin of all axes must match the origin of the toolpath established in the G-code. Failure to set the work origin may cause the cutter to crash and damage the workpiece, machine, or cutter.

Setting Work Origin

1. Clamp workpiece to table, insert cutter, and

load G-code onto controller.

Manually move X- and Y-axes to toolpath

origin established in G-code.

Manually move Z-axis down to 1⁄8" above

workpiece or table surface (as determined by G-code).

Press HOME. Verify all axes move to their

farthest positions.

2. Verify all machine parameters listed in Verifying Parameters on Page 23.

-30-

Place piece of paper between cutter tip and

surface. Slowly step Z-axis down while sliding paper until paper cannot move.

Press XY->0 to set X- and Y-axis origin.

Press Z->0 to set Z-axis origin.

Model G0931 (Mfd. Since 02/21)

Setting Z-Axis Origin With Tool Setter

1. Verify tool setter parameters are correct

according to Verifying Default Parameters on Page 23.

Clamp workpiece to table, insert cutter, and

load G-code to controller.

Place tool setter on top of table or workpiece.

Creating G-Code File

Before operations can be run on the Model G0931, a toolpath must be designed and converted to G-code. CAM software converts a CAD model into G-code, which defines a toolpath for the project, and then formats the G-code into a machine specific dialect via a post-processor.

4. Manually move X- and Y-axes so cutter is directly above tool setter (see Figure 25).

Cutter

Tool

Setter

Figure 25. Cutter over tool setter.

Hold down MENU button, press ON/OFF

button, then release both buttons together. Spindle will lower until cutter reaches tool setter, then raise slightly.

Note: Tool setter uses a magnet to determine

cutter position. Z-axis origin is set at base of tool setter.

This machine does not read advanced formatting by default; it only runs letter addresses for simple axis movement. Review Changing Advanced Settings on Page 33 for information about turning on additional G-code functions.

An operator could also write G-code manually. Often, this is more efficient than designing and processing through CAD/CAM. In addition, knowledge of G-code is integral to refining toolpaths produced by CAM software.

Needed Qty

Items

CAD/CAM Software or Text Editor .................... 1

USB Drive 16GB or Less

To create G-code:

Load CAD file into CAM software. Take into

consideration what type of material will be cut and what type of cutter will be used. Make note of where you will place clamps.

Run post-processing application to export

G-code.

Model G0931 (Mfd. Since 02/21)

Note: Use post-processing options specific

to the Model G0931 or the RichAuto A11 controller when available. If a post-processor for this machine isn't available, use a postprocessor with minimal formatting.

Do a practice run within software to identify

any areas of concern (double-check feed/ speed rates, depth of cut, and direction cutter will be traveling).

Review G-code and simplify code if needed.

Export G-code to USB drive in .NC, .PLT,

.TAP, or .TXT format.

maintenance, or service.

Schedule

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

Cleaning &

Protecting

Cleaning the Model G0931 is relatively easy. Use a brush and shop vacuum to remove debris from the table, rails, and machine surfaces. Never blow off the Model G0931 with compressed air, as this could force debris deep into the mechanisms and airborne material fragments may cause injury to yourself or bystanders.

Ongoing

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

• Loose mounting bolts.

• Damaged or dull cutter.

• Clogged or dirty collet, spindle nut, or spindle collet hole.

Blocked dust collection.

•

• Worn or damaged wires.

• Low or dirty water in coolant bucket.

• Any other unsafe condition.

Daily Maintenance

• Check tubing and connections for coolant system, and fill water reservoir as needed.

Weekly Maintenance

Clean cutter.

•

• Clean/vacuum dust buildup in T-slots.

• Clean/lubricate ball screw and guide rail metal surfaces.

• Inspect spoilboard for defects and flatness.

Lubrication

By design, the ball screws, rails, and other metal parts on this machine have hardened surfaces that are highly resistant to corrosion and wear. However, periodically wipe metal parts with light machine oil (see ACCESSORIES on Page 37) to extend their life.

Note: Lubrication can cause sludge build-up that will bind moving parts, and corrosion can still occur if catalysts are trapped beneath lubricant. Always clean surfaces before applying any form of lubrication.

Driver DIP Switches

The DIP (Dual In-line Package) switches on the stepper drivers control the step size, current, and speed of the stepper motors. If the DIP switches are not configured properly, erroneous signals will cause the stepper motors to function incorrectly.

To set stepper driver DIP switches:

1. DISCONNECT MACHINE FROM POWER!

2. Open electrical cabinet and locate (3) stepper

driver DIP switches (see Figure 48).

— If DIP switch does match diagram, DIP

switch is set correctly.

— If DIP switch does not match diagram, flip

individual rocker switches until DIP switch matches diagram.

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.
