The following directions will give the beginner a start on jointer operations. Use scrap pieces of lumber to check the

settings and to get the feel of the operations before attempting regular work.

NOTE: 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 to help eliminate uneven wear of

the knives.

Always use cutterhead guard and keep hands away from cutterhead. Use push blocks whenever

possible.

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 der way, the new surface rests firmly on the outfeed

table as shown in Fig. 38. 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. 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. 37A.

Do not perform jointing operations on

material shorter than 10 inches (254 mm), narrower

than 3/4 inch (19 mm), or less than 1/2 inch (12.7

mm) thick (refer to Fig. 39).

1. JOINTING OPERATIONS – Jointing cuts or

edge jointing are made to square an edge of a

workpiece. The workpiece is positioned on the

jointer with the narrow edge of the workpiece

on the infeed table and the major flat surface of

the workpiece against the fence, as shown in Fig.

37A. The workpiece is moved from the infeed

table, across the cutterhead to the outfeed table.

2. PLANING OPERATIONS – Planing or surfacing

are identical to the jointing operation except for

the position of the workpiece. For planing, 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.

37B. The workpiece is moved from the infeed table,

across the cutterhead to the outfeed table. Use

push blocks when performing planing operations

whenever possible.
