weight of the tool and load. Due to the variety of applications possible for this jack,  
proper hardware suited for the application must be supplied by the user and proper  
mounting procedures must be followed by the installer. If you are not familiar with  
this type of work or have any doubt about your capability to safely install this jack,  
have a qualified technician install the jack for you. To secure the top of the Hydraulic  
Jack, slide a pin (not included) through the product and Ram (13). Make sure the  
pin’s diameter is a push fit with just enough clearance so that it can move freely.  
The pin should be held in place with appropriate clips or hardened cotter pins (not  
included)..  
Note:  
wArNiNg! The pin must be rated to support at least 8 tons (~16,000  
pounds) of pressure. (see Figure A.)
