 Always close the faceplate before applying any force or load to the OX BLOCK.

7.

 Always ensure the friction bar safety gate is closed before applying any force or load

     to the OX BLOCK.  

 

8.

 Wear to the friction bar is minimized when ropes are clean and descent speed is 

       minimized; loads must never be allowed to run or free fall. 

9.

  Slack must be kept out of the system to prevent high-impact falls. 

10. 

The OX BLOCK is intended for use by medically fit, specifically trained, experienced

        users.

        eliminated. There are many ways to misuse this equipment—too many to list or even 
        imagine. You must personally understand and assume all risks and responsibilities of 
        using this equipment. If you cannot or do not want to do this, do not use this equipment.

  

  

INSPECT BEFORE AND AFTER EACH USE

The inspection should include, but not be limited to the following: 
* Check all parts to ensure no corrosion, cracks, deformation, gouges or scratches, rough 
   areas or sharp edges that may abraid the rope or excessive wear exists. 
* That the sideplate rotates normally & the button operates properly. 
* The button is not be impaired by dirt, ice, corrosion, etc. 
* Swivel / shackle top rotates freely and has no excessive vertical movement.
* The swivel / shackle top bolt is tight and the roll pin used to hold it is in place.

INSPECT DURING USE
Regularly inspect and monitor OX BLOCK while in use, confirming proper connections, 
position, fully locked faceplates and gate, and fully extended buttons.

The OX BLOCK like all equipment must be replaced by the user at regular intervals. This 
interval should be dictated by the amount of use and type of service the product receives 
rather than a set time frame. Therefore the manufacturer does not place a time limit on 
replacement of the OX BLOCK.  Due to the rigorous strain the OX BLOCK endures, it should 
be replaced at the earliest signs of wear.  OX BLOCK inspection is extremely important and 
must as a minimum be performed as stated.

If any evidence of wear or deterioration as outlined is observed, immediately cease use, 
destroy the product, and replace it with new equipment.  Should any unusual conditions 
not outlined above be observed or you have reasonable doubt about a particular condition, 
remove the equipment from service and notify your Supervisor, Safety Director, or contact 
Buckingham Mfg. Co. for clarification.

MAINTENANCE & STORAGE

Clean if necessary with fresh water, then allow to dry completely without using excessive 
heat. The button may be cleaned by holding it upside down & spraying a light lubricant into 
it while operating it. Store in a dry place away from extremes of heat and cold, and avoid 
chemical exposure.

PRINCIPAL MATERIAL

Aluminum alloy, anodized.
