IX. SET-UP, ADJUSTMENT & USE

NOTES:

1. Work Surface For Set-Up:

Use a flat surface, such as a table, to assemble, adjust and check your scooter. This makes the steps easier and helps ensure a correct set-up.

2.Fasteners:

•Many of the screws and bolts on this scooter are special high-strength fasteners and may have special coatings.

•Many nuts are of the Nylock type. They have a plastic insert to help prevent loosening.

1.Use of improper fasteners may cause the scooter to fail.

2.Over- or under-tightened fasteners may fail or cause damage to parts.

3.If bolts or screws become loose, tighten them as soon as you can. Loose bolts or screws can cause damage to other parts causing them to fail.

3.Washers & Spacers:

•Note the position of washers and spacers before disassembly.

•To avoid damage to the frame, replace all washers and spacers when you reassemble parts.

4.Torque Settings:

•A torque setting is the optimal tightening for a particular fastener. Use a torque wrench that measures 120 inch-pounds to secure screws, nuts and bolts on this scooter.

NOTE– Unless otherwise noted, use a torque setting of 120 inch-pounds for all fasteners.

TOOLS YOU WILL NEED

1. Basic Tool Kit:

To set-up, adjust and maintain your scooter you will need the following tools:

2. Torque Wrench:
