This power feeder greatly simplifies repetitive operations on table saws, jointers, and shapers by automating how workpieces are fed into the cut.

Since the power feeder is typically positioned between the blade and the operator during opera- tions, the operator???s hands do not need to get near the blade when feeding the workpiece, so the danger of an accidental cutting injury is greatly reduced.

Additionally, the power feeder provides more con- sistent results than hand fed operations, because it moves the workpiece at an even speed and maintains consistent workpiece pressure against the table and fence throughout the cut.

The power feeder works by simply attaching rub- ber rollers to a motor through a series of gears designed to control the roller speed.

Since the rubber rollers must be positioned correctly to maintain even workpiece pressure against the table and fence, the power feeder is mounted on a stand that allows it to be moved and locked at an array of heights an angles within the range of the stand.

The power feeder stand is typically mounted to the desired machine by clamping it to the machine???s table, or mounting it directly into the machine???s table via drilled and tapped holes.

You MUST assemble all guards, fences, and holdowns before starting your machine or power feeder. Failure to heed this warning could result in serious personal injury.

To correctly position this power feeder on your table top, completely assemble the power feeder first in the order of A, B and C as shown in

Figures 6 and 7. Next, refer to Base Mounting on Page 14. With the power feeder unit completely assembled, it will be easier to locate where on the table top you will need to drill your base mounting holes, so you can take advantage of the full range of power feeder swing and adjustments.

Base Mounting

Position the power feeder on the table top to determine where to drill your base mounting holes, so you can maximize power feeder swing and adjustment options.

There are two mounting options available:

Through Bolt Mounting and Direct Mounting

(discussed on Page 15). Choose an option that suits your requirements.

Whichever way you mount your power feeder, you must be able to use the handcranks and lock levers to position the rubber wheels parallel with the table surface and 1???8" lower than the thickness of your workpiece.

Also, you must be able to point the power feeder slightly towards the machine fence (Figure 8). In other words, the tracking of the power feeder must be toed-in approximately 1?? to 1.5?? degrees toward the machine fence so the rubber wheels slightly push the workpiece against the fence during cut- ting operations.

Figure 8. Typical power feed mounting on a shaper, jointer, and tablesaw.

Mounting Options

To correctly position this power feeder on your table top, completely assemble the power feeder first, then refer to this section and mount your base to the table using one of the two methods below. The reason for this order is that with the power feeder unit completely assembled, it will be easier to locate where on the table top you will need to drill your base mounting holes, so you can take advantage of the full range of power feeder swing and adjustments.

Through-Bolt Mounting

We recommend that you mount your new power feeder to the machine table with through bolts, nuts, and washers (Figure 9). This option will give the most rigidity and clamping strength to prevent the feeder base from twisting out of align- ment during use. However, if under-table support webs interfere with washer or nut locations under the table, you must use an optional clamping kit, or drill and thread holes directly into the table as described in Direct Mounting.

Direct Mounting

Use the included mounting template to drill and tap your table, so the power feeder base can be directly mounted to the table surface (Figure 10). If the table is thinner than 3???8" thick where the threaded holes would be drilled and tapped, or if support webbing is in the way, the threads may strip or loosen as the power feeder is used. Thread locking compound will not cure this situ- ation. Revert to the Through-Bolt Mounting option. In any case, make sure to use a medium- grade liquid thread locking compound on all threads.

Figure 9. Through-bolt mounting.

Figure 10. Direct mounting.

Test Run

Once the power feeder assembly is complete and it is mounted on the table, you must test run your power feeder to make sure it runs properly.

If, during the test run, you cannot easily locate the source of an unusual noise or vibration, stop using the power feeder immediately, then review the Troubleshooting table on Page 21.

If you still cannot remedy a problem, contact our Technical Support at (570) 546-9663 for assis- tance.

Loose hair, clothing, or

jewelry could get caught

in machinery and cause

serious personal injury.

Keep these items away from moving parts at all times to reduce this risk.

To test run the power feed:

1.Read the entire instruction manual first!

2.Make sure all tools and foreign objects have been removed from the tabletop area.

3.Make sure that the power feeder gearbox oil level is full, the oil level should be 1" below the oil fill port. See Figure 1 on Page 5 for oil fill port location.

4.Ensure that all tools and objects used during set up are cleared away from the machine.

5.Adjust and lock the power feeder so the wheels are held approximately one inch above the table and nothing will interfere with wheel rotation.

6.Connect the power feeder to the power sup- ply and use the feed direction switch (Figure 11) to test operation in both FOR and REV directions.

??? Listen and watch for abnormal noises or vibrations. The power feeder should run smoothly.

???Correct for any unusual noises or vibra- tions before operating the power feeder any further. Always disconnect the power feeder from power when investigating or correcting potential problems.

Figure 11. Feed direction switch.

SECTION 4: OPERATIONS

To reduce the risk of serious injury when using this machine, read and understand this entire manual before beginning any operations.

Damage to your eyes and lungs could result from using woodworking machinery without proper protective gear. Always wear safety glasses and a respirator when operating this machine.

Loose hair, clothing, or

jewelry could get caught

in machinery and cause

serious personal injury.

Keep these items away from moving parts at all times to reduce this risk.

NOTICE

If you have never used this type of machine or equipment before, We strongly rec- ommend that you read books, trade maga- zines, or get formal training before begin- ning any projects. Regardless of the con- tent in this section, Grizzly Industrial will not be held liable for accidents caused by lack of training.

Model G4176 1???4 HP Power Feeder

You MUST assemble all guards, fences, and hold-downs before starting your machine or power feeder. Failure to heed this warning could result in amputation or death!

Power feeders reduce kickback hazards and improve cutting results by feeding in a consistent and stable manner. Remember, do not to stand in the path of potential kickback.

When not in use, support the power feeder with a wooden block so the rubber wheels are raised above the table and do not compress from the weight of the power feeder.

The universal joints on this power feeder allow you to adjust the power feeder tracking and height to accommodate many workpiece sizes. Before loosening any lock lever, always support the power feeder with a block of wood, so the power feeder does not drop and cause damage.

Adjust the power feeder so it is toed-in approxi- mately 1?? to 1.5?? degrees towards the machine fence. This adjustment will ensure that the power feeder wheels slightly push the workpiece against the fence during cutting operations (Figure 8).

Next, adjust the power feeder so the rubber wheels are parallel with the table surface, and are 1???8" lower than the thickness of your workpiece. This adjustment ensures that the workpiece will not slip or hang in the middle of a cut. Always double check that the power feeder wheels are 1???8" lower than the workpiece before you begin feed- ing operations. Otherwise, the workpiece may slip and kickback.

Changing Feed

Speed

Your power feeder has the option to feed a workpiece at six different feed rates: 13, 18, 25, 30, 41, and 62 feet per minute. These rates are achieved by changing the combination of change gears in the power feeder gear box.

Always disconnect power to the machine before performing maintenance. Failure to do this may result in serious person- al injury.

To change the feed rate of your power feeder:

1.Move the switch to the OFF position.

2.DISCONNECT THE POWER FEEDER

FROM POWER!

3.Refer to the change gear chart on the inside of the chain cover (Figure 12) or the table (Figure 13) to find the gear combination required for your chosen feed rate.
