The information in this manual has been obtained from sources believed to be reliable and as up-to- date as possible. We have focused primarily on the proper assembly and adjustment of your power feeder – as well as some basic information on using the power feeder on specific machines. We have also included some important safety measures which we believe to be essential to this machine’s operation. While most safety measures are generally universal, Grizzly cautions that each workshop is differe

7. KEEP CHILDREN AND VISITORS AWAY. All children and visitors should be kept a safe dis- tance away from your work area. 8. MAKE WORKSHOP CHILD-PROOF with padlocks, master switches, or by removing starter keys. 9. DO NOT FORCE TOOL. Tools work better and more safely when they are allowed to work at their own speed. 10. USE THE RIGHT TOOL. Do not use a tool or an attachment to do a job it wasn’t intended for. 11. WEAR PROPER APPAREL. Do not wear loose clothing, gloves, neckties, or jewelry that m

IV. UNPACKING The Model G1778 Power Feeder is shipped from the factory in two heavy-duty cardboard packages. Find a clear work area to open the packages and inventory their contents. Use particular care, when unpacking the boxes, to inspect all of the parts for damage incurred during shipping. If you find the machine is damaged after you’ve signed for delivery and the truck and driver are already gone, you will need to file a freight claim with the carrier. Save the containers and all pack- ing

VI. CLEAN-UP All of the unpainted surfaces on this machine – and a few of the painted ones – are coated with a rust preventative oil. The coating can be removed with paint thinner (mineral spirits) and a good sup- ply of paper towels. DO NOT use gasoline, lacquer thinner, acetone, or other highly-flammable solvents to remove the coating. The possibility of flash fire or explosion is far greater and they don’t work much better than mineral sprits anyway. Don’t use chlorinated solvents, such as pe

VIII. ASSEMBLY Most of the power feeder has been assembled at the factory. The remaining assembly requirements should not take a large amount of time. Take a moment to examine the parts diagrams at the back of this manual to familiarize yourself with the various parts.

Three setscrews hold the column cap to the horizontal column. You will need to loosen those setscrews to properly seat the column cap on the column. Two of the setscrews are seen in Figure 3. At this point, attach the handles to the handwheels with a 12mm open end wrench. 2.75" 3/8" (Through Bolt) "F" Bit (Tapped) Figure 3 Figure 4 Once the first three components are attached, snug up the guide bolt on the column bracket.

to the angled joints. The roller casing mounts in an identical fashion as described for the angle joints. Attach the knob on the roller casing to the 45° angle joint and tighten the locking lever. Once the motor and roller assembly is attached to the angle joints, attach the entire unit to the col- umn assembly. The column clamp may need to be spread slightly to attach it to the horizontal col- umn. Use extreme care when spreading the clamp. Too much force could break the casting. Leading Traili

3. Turn the feed rollers so they are angled just slightly toward the fence. The leading wheel should 1 be just about /4" closer to the fence than the trailing wheel. 1 1 4. Set the wheel height between /16" and /8" below the height of the material you intend to mill. The wheels, when properly adjusted, will put consistent downward pressure on your workpiece. See Figure 7. Figure 8 Figure 7 The power feeder can also be set to support your work against a fence, as shown in Figure 8. As with the p

B. FEED RATES The optimum feed rate for the Model G1778 Power Feed will vary depending on a number of fac- tors, including; the thickness of the material to be cut, the hardness of the workpiece, the speed of the cutting tool and the configuration of the cutting tool (number of teeth, shape of cutter, etc. Generally, the following rules can be followed with a good level of success. • The thicker the material to be cut, the slower the feed rate. • The harder the material, the slower the feed rate
