WARNING: When using product, basic safety precautions should always be followed
to reduce the risk of personal injury and damage to equipment.

Read all instructions before using this product!

1. Keep work area clean. Cluttered areas invite injuries.

2. Observe work area conditions. Don’t expose to rain. Keep work area well lighted.

3. Keep children away. Children must never be allowed in the work area. Do not let
them play with or ride on the Cart.

4. Store idle equipment. When not in use, the Cart must be stored in a dry location to
inhibit rust.

5. Use the right product for the job. Do not attempt to force a small Cart to do the
work of a larger industrial Cart. There are certain applications for which this Cart was
designed. It will do the job better and more safely at the rate for which it was intended.
Do not modify this Cart and do not use this Cart for a purpose for which it was not
intended.

6. Dress properly. Do not wear loose clothing or jewelry as they can be caught in
moving parts. Protective, electrically non-conductive clothes and non-skid footwear
are recommended when working. Wear restrictive hair covering to contain long hair.

7. Use eye protection. Always wear ANSI approved impact safety goggles during
assembly.

8. Do not overreach. Keep proper footing and balance at all times.

The handle must be kept clean, dry, and free from oil and grease at all times.

10. Stay alert. Watch what you are doing, use common sense. Do not operate the Cart
when you are tired.

11. Check for loose and damaged parts. Before using the Cart, any part that appears
damaged should be carefully checked to determine that it will operate properly and
perform its intended function. Check for alignment and binding of moving parts; any
broken parts or mounting fixtures; and any other condition that may affect proper
operation. Any part that is damaged should be properly repaired or replaced by a
qualified technician.

12. Replacement parts and accessories. When servicing, use only identical
replacement parts. Use of any other parts will void the warranty.

labels if taking prescription medicine to determine if your judgment or reflexes are
impaired while taking drugs. If there is any doubt, do not operate the Cart.
