SECTION 2: CIRCUIT REQUIREMENTS

220V Single-Phase 220V Three-Phase

G9984 Only:

The Model G9984 has a 3 H.P., 1725 R.P.M. motor which requires a 220V single-phase circuit. The cord set included does not have a plug, as the style of plug you require will depend upon the type of service you currently have or plan to install. The motor will safely draw about 16 amps at 220V under load. If you operate the Model G9984 on any circuit that is already close to its capacity, it might blow a fuse or trip a circuit breaker. However, if an unusual load does not exist, and the circuit breaker still trips, have the circuit inspected by a qualified electrician.

In preparing to connect the Model G9984 to your existing or new circuit, it will be necessary to connect a plug that matches your 220V receptacle. If you will be installing a new receptacle and plug, we recommend using a NEMA-style L6-20 plug

and outlet shown in Figure 1.

The Model G9984 should be fused at 20 amps. Do not attempt to modify an existing circuit by replacing the circuit breaker with one rated for a higher amperage than the plug, outlet and wiring can handle. Make sure that existing electrical wires are capable of handling a 20 amp current. If you are unsure, seek the assistance of a qualified electrician.

Figure 1. NEMA-style L6-20 plug and outlet. Figure 2. NEMA-style L15-20 plug and outlet.

G9985 Only:

The Model G9985 has a 3 H.P., 1725 R.P.M. motor which requires a 220V three-phase circuit. The cord set enclosed does not have a plug, as the style of plug you require will depend upon the type of service you currently have or plan to install. The motor will safely draw about 9 amps at 220V under load. If you operate the Model G9985 on any circuit that is already close to its capacity, it might blow a fuse or trip a circuit breaker. However, if an unusual load does not exist, and the circuit breaker still trips, have the circuit inspected by a qualified electrician.

In preparing to connect the Model G9985 to your existing or new circuit, it will be necessary to connect a plug that matches your 220V receptacle. If you will be installing a new receptacle and plug, we recommend using a NEMA-style L15-20 plug

and outlet shown in Figure 2.

The Model G9985 should be fused at 20 amps. Do not attempt to modify an existing circuit by replacing the circuit breaker with one rated for a higher amperage than the plug, outlet and wiring can handle. Make sure that existing electrical wires are capable of handling a 20 amp current. If you are unsure, seek the assistance of a qualified electrician.

-6- G9984/G9985 Oscillating Belt Edge Sander

We do not recommend the use of extension cords with 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. Refer to the chart in Section 1: Safety Instructions to determine the minimum gauge for

the extension cord when using either 110V or 220V. The extension cord must also contain a ground wire and plug pin. Always repair or replace extension cords when they become worn or damaged.

We have covered some basic electrical requirements for the safe operation of your 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.

Grounding Extension Cords

In the event of an electrical short, grounding provides electric current a path of least resistance to reduce the risk of electrical shock. This tool is 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.

Improper connections of the electrical-grounding conductor can result in the risk of electric shock. The conductor with green or green and yellow striped insulation is the electrical-grounding conductor. If repair or replacement of the electric cord or plug is necessary, do not connect the equipment grounding conductor to a live terminal.

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 injury may occur.

Unpacking

The Model G9984/G9985 is shipped from the manufacturer in a carefully packed carton. If you discover the machine is damaged after you have signed for delivery, immediately call Customer Service for advice.

The Model G9984/G9985 has two lifting rings located on the top of the access door as shown in

Figure 3.

When using a lifting apparatus to move the machine, always lift from both of these designated rings. Lifting at any other location, or from only one ring at a time, could cause the machine to become unbalanced and tip over. A hydraulic pallet jack or fork lift can also be used. Damage from improper moving methods may void the warranty.

Keep the lifting rings in a safe location where they will not become lost. These rings will need to be re-installed if the machine is ever to be lifted and moved in the future.

When the machine is in its final location, replace the lifting rings with the star knobs as shown in

Figure 4. Be sure to place the 10mm flat washers

and 10mm lock washers on the star knobs threaded post before installing. These washers help the star knobs remain secure and protect the finish of the machine.

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 such as Grizzly’s G7895 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 smoke while using solvents. A risk of explosion or fire exists and may result in serious personal injury.

Do not use gasoline or other petroleum-based solvents. They have low flash points which make them extremely flammable. A risk of explosion and burning exists if these products are used. Serious personal injury may occur if this warning is ignored.

Many of the solvents commonly used to clean machinery can be toxic when inhaled or ingested. Always work in wellventilated 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.

Site Considerations

FLOOR LOAD

Your Model G9984/G9985 represents a large weight load in a medium footprint. Most commercial or home shop floors should be sufficient to carry the weight of the Model G9984/G9985. If you question the strength of your floor, you can opt to reinforce it. Ensure that the stand or bench you use with the Model G9984/G9985 is capable of supporting the machine.

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 and keep dust collection hoses off the floor and out of the way.

LIGHTING AND OUTLETS

Lighting should be bright enough to eliminate shadows 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.

-12- G9984/G9985 Oscillating Belt Edge Sander

SECTION 4: ASSEMBLY

Most of your Model G9984/G9985 has been assembled at the factory, but some parts must be assembled or installed after delivery.

TOOLS REQUIRED: You will need a small

adjustable wrench, a flat and Phillips head screwdriver, and a machinist’s square.

Four rubber feet are furnished to help absorb machine vibration, to even out imperfections in the floor, and to protect the machine from general stress. To install the rubber feet:

1. Thread the end of the rubber feet into the

threaded holes on the underside of the base

supports as shown in Figure 6.

2. Do not overtighten the feet. Cast iron threads

are softer than the steel threads on the feet. Overtightening can cause the cast iron threads to become stripped.

Rubber Feet

Figure 6. Attaching rubber feet.

Disconnect power to the machine when performing any assembly procedures on the Model G9984/G9985. Failure to do this may result in serious personal injury.

Keep loose clothing rolled up and out of the way of machinery and keep hair pulled back.

Wear safety glasses during the entire assembly process. Failure to comply may result in serious personal injury.

Some metal parts may have sharp edges on them after they are formed. Please examine the edges of all metal parts before handling them. Failure to do so could result in injury.
