little. Reinsert caster stem and clevis pins.

Operating Your RocknRoller® Multi-Cart®

Multi-Carts instantly transform into any of 8 different configurations: 1. short furniture dolly, 2. long-nose luggage cart 3. storage/transport, 4. short platform
cart, 5. short hi-stacker, 6. long furniture dolly, 7. long hi-stacker, 8. long platform cart. When using Multi-Cart in extended 4-wheel dolly configuration, distribute load evenly over frame bed when possible, placing the heaviest items over the large rear wheels to make rolling easier. Over rough terrain it is recommended to push cart with the large wheels forward. Caution: When loading equipment on a hill or incline, set brake. (Block wheels if load is very
heavy). Caution should be used when moving any load with Multi-Carts or any other dolly.
