you tamper with it.

Check the Tension
WARNING A raised and badly supported machine can fall on you. Position the machine on a firm, level
surface before raising one end. Ensure the other end is securely chocked. Do not rely solely on the machine
hydraulics or jacks to support the machine when working under it. Disconnect the battery, to prevent the
engine being started while you are beneath the machine.
