SAFETY WARNINGS AND PRECAUTIONS

WARNING: When using winch, basic safety precautions should always be followed to re-

duce the risk of personal injury and damage to equipment.

Read all instructions before using this tool!

1. Always wear ANSI approved impact safety goggles when operating the winch.

2. Donotexceedwinchloadweightcapacity(seespecications).

3. Be certain winch is properly bolted to a truck bed that can hold the winch load.

4. Always use proper couplings when connecting winch cable hook to load cable or

rope.

5. Donotoverloadthewinch.Staywithinthecapacitylevelsshowninthespecications.

6. Do not use inappropriate attachments to extend the length of the winch cable.

7. Never lift people or hoist loads over people.

8. Never come between the winch and the load when operating.

9. Do not apply load to winch when cable is fully extended. Keep at least 4 full turns of

cable on the reel.

10. After moving an item with the winch, secure the item. Do not rely on the winch to hold

it for an extended period. The winch does not have a locking key.

11. Examine winch before using. Components may be affected by exposure to chemicals,

salts, and rust.

12. Never fully extend cable while pulling a load. Keep 4 complete turns of cable around
