WARNING

To prevent personal injury or property damage, do not start the engine until all assembly steps are complete and you have read and understand the safety and operating instruc- tions in this manual.

Introduction

Carefully follow these assembly steps to correctly prepare your tiller for use. It is recommended that you read this Section in its entirety before beginning assembly. NOTE: Engine syles vary by model. The engine on your tiller may appear differ- ently than those shown in illustrations and Figures throughout this manual.

Inspect unit

Inspect the unit and carton for damage immediately after delivery. Contact the carrier (trucking company) if you find or suspect damage. Inform them of the damage and request instructions for filing a claim. To protect your rights, put your claim in writing and mail a copy to the carrier within 15 days after the unit has been delivered.

STEP 1: Unpacking Instructions

1.Remove any cardboard inserts and packaging material from the carton. Remove any staples from the bottom of the carton and then lift the carton up and off the unit.

2. The tiller is heavy and you should not attempt to remove it from the shipping platform until the handlebars are installed. The procedure for removing the tiller is explained in Step 3 of these assembly steps.

NOTE: Be careful not to severely bend any of the control cables on the unit.

3.Remove all unassembled parts and the separate hardware bag from the carton. Check that you have the items listed below (contact your local dealer or the factory if any items are missing or damaged). NOTE: Use the screw length template (Fig. 2-1) to identify screws.
