1. All grounded, cord-connected machines:

In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This machine is equipped with an electric cord having an equipment- grounding conductor and 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.

Do not modify the plug provided - if it will not fit the outlet, have the proper outlet installed by a qualified electrician.

Improper connection of the equipment-grounding conductor can result in risk of electric shock. The conductor with insulation having an outer surface that is green with or without yellow stripes is the equipment- 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.

Check with a qualified electrician or service personnel if the grounding instructions are not completely understood, or if in doubt as to whether the machine is properly grounded.

Use only 3-wire extension cords that have 3-prong grounding type plugs and matching 3-conductor receptacles that accept the machine???s plug, as shown in Fig. A.

Repair or replace damaged or worn cord immediately.

POWER SOURCE.

Positive stops are provided to limit the height and depth of the infeed table. To adjust the stops, loosen two locknuts (F) and (G) Fig. 37, and turn the two adjusting screws (J) and (K) as required. Then retighten the locknuts (F) and (G). A good suggestion is to set the upper positive stop (J) for your finish or final cut. This means that you will be able to rapidly set the infeed table for a finish or final cut without checking the scale and pointer. Also the lower positive stop (K) can be set for the maximum depth-of-cut or if you desire to limit the depth-of-cut, adjust the stop screw (K) accordingly.

HANDLING THE KNIVES, AS THE CUTTING EDGES

ARE VERY SHARP.

If the knife is to be lowered it will be necessary to carefully push down on the knife with a scrap piece of wood, after screws (F) have been turned. Tighten four screws (D) Fig. 41, by turning them counterclockwise, after adjustment is made.

6.Repeat these procedures for adjusting the remaining two knives if necessary, and replace cutterhead guard removed in STEP 2.

7.If the knives are set too low, the result will be as shown in Fig. 43, and the finished surface will be curved.

8.If the knives are set too high, the work will be gouged, curved, or bowed at the end of the cut, as shown in Fig. 44.

9.As a final check, run a piece of work slowly over the knives for 6 to 8 inches. The wood should rest firmly on both tables as shown in Fig. 45, with no open spaces under the finished cut.

As the fence is moved across the table, the rear cutterhead guard (C) covers and guards the cutterhead in back of the fence. NOTE: Lock handle (A) is spring-loaded and can be repositioned by pulling up on the handle and repositioning it on the serrated nut located underneath the hub of the handle.

2.To tilt the fence in or out, loosen lock handle (D) Fig.

48.While holding fence tilting handle (E) Fig. 49, rotate 90?? flip stop (G) and tilt the fence to the desired angle, in or out, and tighten lock handle (D) Fig. 48. IMPORTANT: When cutting bevels and the angle is small, there is little difference whether the fence is tilted in or out; however, at angles approaching 45 degrees it may become difficult to hold the work securely against the fence when the fence is tilted out. In these cases we suggest that the fence be tilted toward the table, as shown in Fig.

50.The fence will form a V-shape with the tables and the work is easily pressed into the pocket while passing across the knives.

The following directions will give the beginner a start on jointer operations. Use scrap pieces of lumber to check settings and to get the feel of the operations before attempting regular work.

THE KNIVES ON THE JOINTER WILL

NOT WEAR EVENLY BY FEEDING THE WOOD

THROUGH THE SAME SPOT ON THE TABLE EVERY

TIME. FEED THE WOOD THROUGH THE JOINTER AT

DIFFERENT SPOTS ON THE TABLE WHEN

POSSIBLE, TO HELP ELIMINATE UNEVEN WEAR OF

THE KNIVES.

ALWAYS USE CUTTERHEAD GUARD

AND KEEP HANDS AWAY FROM CUTTERHEAD.

ALWAYS USE PUSH BLOCKS WHENEVER

POSSIBLE. NEVER MAKE JOINTING AND PLANING

CUTS DEEPER THAN 1/8" IN ONE PASS.

PLACEMENT OF HANDS

DURING FEEDING

At the start of the cut, the left hand holds the work firmly against the infeed table and fence, while the right hand pushes the work toward the knives. After the cut is un- derway, the new surface rests firmly on the outfeed table as shown in Fig. 61. The left hand should then be moved to the work on the outfeed table, at the same time maintaining flat contact with the fence. The right hand presses the work forward, and before the right hand reaches the cutterhead, it should be moved to the work on the outfeed table.

NEVER PASS HANDS DIRECTLY OVER

THE CUTTERHEAD.

JOINTING AN EDGE

This is the most common operation for the jointer, these cuts are made to square an edge of a workpiece. Set the guide fence square with the table. Depth of cut should be the minimum required to obtain a straight edge. Hold the best face of the piece firmly against the fence throughout the feed as shown in Fig. 61.

MAXIMUM DEPTH OF CUT SHOULD

NOT BE MORE THAN 1/8" IN ONE PASS.

Fig. 60

Fig. 61

Fig. 62

SURFACING

Surfacing is identical to the jointing operation except for the position of the workpiece. For surfacing, the major flat surface of the workpiece is placed on the infeed table of the jointer with the narrow edge of the workpiece against the fence, as shown in Fig. 63. The workpiece is moved from the infeed table, across the cutterhead to the outfeed table establishing a flat surface on the workpiece

ALWAYS USE PUSH BLOCKS WHEN

PERFORMING SURFACING OPERATIONS AND NEVER

PASS YOUR HANDS DIRECTLY OVER THE

CUTTERHEAD.

MAXIMUM DEPTH OF CUT SHOULD

NOT BE MORE THAN 1/8" IN ONE PASS.

BEVELING

To cut a bevel, lock the fence at the required angle and run the work across the knives while keeping the work firmly against the fence and tables. Several passes may be necessary to arrive at the desired result. When the angle is small, there is little difference whether the fence is tilted to the right or left. However, at greater angles approaching 45 degrees, it is increasingly difficult to hold the work properly when the fence is tilted to the right. The advantage of the double-tilting fence is appreciated under such conditions. When tilted to the left, the fence forms a V-shape with the tables, as shown in Fig. 64, and the work is easily pressed into the pocket while passing it across the knives. If the bevel is laid out on the piece in such direction that this involves cutting against the grain, it will be better to tilt the fence to the right.

SURFACING WARPED PIECES

If the wood to be surfaced is dished or warped, take light cuts until the surface is flat. Avoid forcing such material down against the table; excessive pressure will spring it while passing the knives, and it will spring back and remain curved after the cut is completed.

SURFACING SHORT

OR THIN WORK

WHEN SURFACING SHORT OR THIN

PIECES, ALWAYS USE PUSH BLOCKS TO MINIMIZE ALL DANGER TO THE HANDS. Fig. 66, illustrates using the Delta Push Blocks properly.

DO NOT PERFORM SURFACING

OPERATIONS ON MATERIAL SHORTER THAN 10

INCHES, NARROWER THAN 3/4 INCH, WIDER THAN

6 INCHES, OR LESS THAN 1/2 INCH THICK (REFER TO FIG. 67).

DIRECTION OF GRAIN

Avoid feeding work into the jointer against the grain as shown in Fig. 68. The result will be chipped and splintered edges. Feed with the grain as shown in Fig. 69, to obtain a smooth surface.
