Tools you will need. The main tool you will need is the star end Allen wrench which comes with the hardware for the Transport Caddy. As an option, if you have a power drill with a star end bit, it would speed up the assembly procedure. Hand tighten the screws to prevent stripping the plastic threads. You will also need a regular Phillips head screwdriver for a couple of the screws.
Attach the support blocks to the bottom of the caddy. Note that there are two holes in the each side of the bottom tube. Use the holes closest to the wheel for the Polaris 9300 Cleaner. The other set of holes is used for the Polaris 9400 Cleaner. Place the flange side of the support block on the outside of the tube frame as shown in the next step.
