Confirm the truck is on a flat level ground.  
 

Inform the truck driver that the MPS 350 is going to be installed, repaired, operated, or adjusted.

Remove the keys from the ignition of the truck. Place signs on the truck that it is being serviced 
– DO NOT START ENGINE. 
 

Add load to the truck. The truck must be loaded to the correct weight before the MPS 350 is 
installed.  The minimum loaded weight is 15,000 pounds (6,815 kg).  This could be different for 
local regulations.  Consult your local governing specifications.
