MOST MOTORHOME POWERPACK INSTALLATIONS WILL REQUIRE RAISING THE FRONT OF THE COACH TO INSTALL
THE BANKS POWERPACK EXHAUST MANIFOLDS. A PAIR OF SUPPORT RAMPS MAY BE CONSTRUCTED AS SHOWN.
CAUTION!
MAKE SURE THE COACH IS ON FIRM LEVEL GROUND WHEN USING THESE RAMPS. SLOWLY DRIVE UP
THE RAMPS WHILE YOU HAVE SOMEONE GUIDE YOU TO KEEP THE VEHICLE CENTERED AS YOU GO AND TO LET
YOU KNOW WHEN YOUR TIRES ARE IN POSITION ON TOP OF THE RAMPS. DO NOT GO UNDER THE COACH UNTIL
YOU ARE SURE IT IS STABLE ON THE RAMPS, THE TRANSMISSION IS IN “PARK” AND THE HAND BRAKE IS SET.
WE ALSO SUGGEST YOU PLACE A BLOCK BEHIND THE REAR TIRES AS AN ADDITIONAL SAFETY MEASURE.
