Switch Arm

The arm (Figure 3) on which the push button switch is located is shipped in the down position. The arm should be pivoted to upright position as shown. Tighten the two screws with a 10mm wrench.

Dust Hood

Before attaching the dust hood, make sure the hole in the dust chute is concealed by the dust chute cover, as shown in Figure 4.

Mount the dust hood to the jointer stand using the seven 1/4 x 1/2 hex cap screws and seven 1/4 lock washers (Figure 5).

It is recommended that a dust collection system of at least 800 CFM be connected to the jointer’s dust hood, via a 6-inch diameter hose.

Grounding Instructions

Electrical connections must be made by a qualified electrician in compliance with all relevant codes. This machine must be properly grounded to help prevent electrical shock and possible fatal injury.

This machine must be grounded. Grounding provides a path of least resistance to help divert current away from the operator in case of electrical malfunction.

Make sure the voltage of your power supply matches the specifications on the motor plate of the machine.

Open the junction box (Figure 6) and connect the wires according to the diagram on the inside of the junction box cover. A similar diagram can be found at the back of this manual. The green wire (ground) must be properly grounded.

The Model 1285 may be fitted with an appropriate plug, or be “hard-wired” to an electrical panel. If hard-wired to a panel, make sure a disconnect is available for the operator.
