W A R N I Investigate the layout of your vehicle thoroughly before drilling or cutting. N Take care when you work near the gas tank, gas lines, hydraulic lines, electri- G cal components and electrical wiring. Do not use the equipment unmounted. Attach this system securely to prevent damage, particularly in the event of an / accident or aggressive driving. Do not mount the system so that wire con- D nections are unprotected or are subjected to pinching or damage from nearby I obje
