Each Prostar Electric Hoist is built in accordance with the specifications contained herein and at the time of manufacture

complied with our interpretation of applicable sections of the National Electrical Code (ANSI/NFPA 70). Installers are required

to provide current overload protection and grounding in keeping with the code. Check each installation for compliance with the

applicable sections of the code as well as the National, State and Local Codes that may apply to the installation. In addition,

safety code requirements associated with the operation of a hoist in the inverted (theatrical) position (chain port up), as with

any mechanical equipment, vary depending upon locality. Therefore, before installing the hoist, the user should consult his

insurance company and/or local authority to see if a deviation is required to permit the use of the hoist in this particular

application.

The safety laws for elevators, lifting of people and for dumbwaiters specify construction details that are not incorporated into

the hoists. For such applications, refer to the requirements of applicable state and local codes, and the American National

Safety Code for elevators, dumbwaiters, escalators and moving walks (ASME A17.1). We cannot be responsible for

applications other than those for which the equipment is intended.

THIS SYMBOL POINTS OUT IMPORTANT SAFETY INSTRUCTIONS WHICH IF NOT
FOLLOWED COULD ENDANGER THE PERSONAL SAFETY AND/OR PROPERTY OF
YOURSELF AND OTHERS. READ AND FOLLOW ALL INSTRUCTIONS IN THIS
MANUAL AND ANY PROVIDED WITH THE EQUIPMENT BEFORE ATTEMPTING TO
OPERATE YOUR PROSTAR HOIST.

Improper operation of a hoist can create a potentially hazardous

situation which, if not avoided, could result in death or serious

injury. To avoid such a potentially hazardous situation, the

operator shall:

1. NOT operate a damaged, malfunctioning or unusually

performing hoist.

2. NOT operate the hoist until you have thoroughly read

and understood this Operating, Maintenance and Parts

Manual.

3. NOT operate a hoist which has been modified.

4. NOT lift more than rated load for the hoist.

5. NOT use hoist with twisted, kinked, damaged, or worn

load chain.

6. NOT use the hoist to lift, support, or transport people.

7. NOT lift loads over people.

8. NOT operate a hoist unless all persons are and remain

clear of the supported load.

9. NOT operate unless load is centered under hoist.

10. NOT attempt to lengthen the load chain or repair

damaged load chain.

11. Protect the hoist’s load chain from weld splatter or other

damaging contaminants.

12. NOT operate hoist when it is restricted from forming a

straight line from hook to hook in the direction of loading.

13. NOT use load chain as a sling, or wrap load chain

around load.

14. NOT apply load to the tip of the hook or to the hook latch.

15. NOT apply the load unless load chain is properly

seated in the chain wheel(s) or sprocket(s).

16. NOT apply load if bearing prevents equal loading on all

load supporting chains.

17. NOT operate beyond the limits of the load chain travel.

18. NOT leave load supported by the hoist unattended

unless specific precautions have been taken.

19. NOT allow the load chain or hook to be used as an

electrical or welding ground.

20. NOT allow the load chain or hook to be touched by a

live welding electrode.

21. NOT remove or obscure the warnings on the hoist.

22. NOT operate a hoist on which the safety placards or

decals are missing or illegible.

23. NOT operate a hoist unless it has been securely

attached to a suitable support.

24. NOT operate a hoist unless load slings or other

approved single attachments are properly sized and

seated in the hook saddle.

25. Take up slack carefully - make sure load is balanced

and load holding action is secure before continuing.

26. Shut down a hoist that malfunctions or performs

unusually and report such malfunction.

27. Make sure hoist limit devices function properly.

28. Warn personnel of an approaching load.

1. Maintain a firm footing or be otherwise secured when

operating the hoist.

2. Check brake function by tensioning the hoist prior to

each lift operation.

3. Use hook latches. Latches are to retain slings, chains,

etc. under slack conditions only.

4. Make sure the hook latches are closed and not

supporting any parts of the load.

5. Make sure the load is free to move and will clear all

obstructions.

6. Avoid swinging the load or hook.

7. Make sure hook travel is in the same direction as shown

on the controls.

8. Inspect the hoist regularly, replace damaged or worn

parts, and keep appropriate records of maintenance.

9. Use factory parts when repairing the unit.

10. Lubricate load chain per instructions in this manual.

11. NOT use the hoist load limiting or warning device to

measure load.

12. NOT use limit devices as routine operating stops

unless allowed by manufacturer. They are emergency

devices only.

13. NOT allow your attention to be diverted from operating

the hoist.

14. NOT allow the hoist to be subjected to sharp contact

with other hoists, structures, or objects through misuse.

15. NOT adjust or repair the hoist unless qualified to

perform such adjustments or repairs.

Improper operation of a hoist can create a potentially hazardous

situation which, if not avoided, could result in death or serious

injury. To avoid such a potentially hazardous situation, the

operator shall:
