To check and adjust the 45-degree stop:

1.Loosen lock handle (D, Figure 22) and tilt fence until it contacts the 45-degree stop (C, Figure 22).

2.Place a machinist’s protractor or similar device set at 45 degrees on the table and against the fence.

3.If adjustment is necessary, loosen the hex nut on the stop screw (C, Figure 22) and turn the stop screw until the fence is flush with the protractor.

4.Retighten the hex nut.

Cutter Guard Tension

The tension of the guard (Figure 24) must always be sufficient during jointer operations to cause the guard to conceal the unused part of the cutterhead, and to swing back to contact the fence after the workpiece has cleared the cutterhead. To adjust the guard tension:

1.Loosen the knob shown in Figure 24 and push the knob to the right to increase guard tension; or to the left to decrease guard tension.

2.Tighten the knob in that position.

Operating Controls

The push button on/off switch is conveniently positioned above the table (Figure 25). Do not remove the clear plastic cover, as this keeps wood dust out of the switch.

Operation

NOTE: If you are inexperienced at jointing, use scrap pieces of lumber to check settings and get the feel of operations before attempting regular work.

Always use the guard whenever possible and keep hands away from cutterhead. Failure to comply may cause serious injury.

Ideally, the fence should be moved forward (toward the front of the machine) to expose only the amount of cutterhead needed for the workpiece.

TIP: If workpieces of the same size are constantly being run on the jointer, the operator may wish to occasionally adjust the fence forward or backward to prevent wear on only one area of the knives.
