3.On the PTO Power Unit, unplug the Forward Interlock Wire Harness that leads from the base of the handlebars (A, Figure 4-28) to the receptacle (B) located on the top, right side of the transmission cover.

4.On the Stationary Attachment, locate the interlock wire (C, Figure 4-28) and clean contacts on plug and receptacle (B). This connection enables you to operate the Wheels/Tines/PTO Drive Lever in FORWARD without having to squeeze a Forward Interlock Lever.

5.Connect the plug from the Stationary Attachment (C, Figure 4-28) to the recep- tacle on the PTO Power Unit (B). The connection must be tight.

Setting Up Non-Powered Attach- ments

1.Move the Tines/PTO Clutch Lever (Figure 4-22) to DISENGAGE.

2.Move the Wheel Speed Lever (Figure 4-22) to either SLOW or FAST position To do this, roll the PTO Power Unit while shifting lever until wheels engage.

3.Verify that the Forward Interlock Wire Harness plug at the base of the handle- bars (A, Figure 4-28) is connected to the Forward Interlock Wire Harness recepta- cle (B) on the top right side of the transmission.

Starting The Engine

IMPORTANT: Refer to Cold Weather Operation instructions, in this section, before operating in temperatures below 40oF.

1.Move the Wheels/Tines/PTO Drive Lever into NEUTRAL. To find NEUTRAL (be sure engine is off), push lever down and engage it in FORWARD then tap the lever upward to automatically move into

NEUTRAL .

2.Move the Tines/PTO Clutch Lever into DISENGAGE position.

WARNING

To avoid injury,do not run the engine in an enclosed or poorly vented area. Engine exhaust contains carbon monoxide, an odorless and deadly gas.

3.Start Engine. See Starting and Stopping the Engine, in the beginning of this section, for detailed starting informa- tion. Also see the Engine Owner's Manual.

4.For non-powered attachments only test the Forward Interlock Safety System. See Testing the Forward Interlock Safety System, in this section, for a procedure.

Operating Stationary Attachments

1.Move Tines/PTO Clutch Lever (Figure 4-22) into ENGAGE.

2.To apply power to PTO-driven attach- ments, move Wheels/Tines/PTO Lever (Figure 4-22) down to FORWARD position (do not use REVERSE with stationary attachments).

3.To stop the PTO Power Unit, tap the Wheels/Tines/PTO Drive Lever upward into NEUTRAL position.

Operating Non-Powered Attachments (or to Tow Stationary Attachments)

1.To move forward, squeeze and hold one Forward Interlock Lever (Figure 4-30) up against the handlebars, and move the Wheels/Tines/PTO Drive Lever down to

FORWARD.

Figure 4-30: Moving tiller forward: squeeze one Forward Interlock Lever and then move Wheels/Tines/PTO Drive Lever down to FORWARD.

2.To stop forward motion, tap Wheels/Tines/PTO Drive Lever upward into NEUTRAL, then release the Forward Interlock Levers.

3.To stop forward motion in an emergency, release all PTO Power Unit controls (stops engine).

4.To move in reverse, reduce the engine speed then shift the Wheel Speed Lever into SLOW. Move and hold the Wheels/Tines/PTO Drive Lever all the way up. Ensure that the area behind you is clear of all obstacles, before moving the lever into REVERSE.

5.To stop moving in REVERSE, release the Wheels/Tines/PTO Drive Lever.
