DO NOT DRIVE WITH BOOM EXTENDED OR ABOVE HORIZONTAL EXCEPT ON A
SMOOTH, FIRM AND LEVEL SURFACE.
TO AVOID LOSS OF TRAVEL CONTROL OR UPSET ON GRADES AND SIDESLOPES, DO NOT
DRIVE MACHINE ON GRADES OR SIDESLOPES EXCEEDING THOSE SPECIFIED ON MANU-
FACTURERS NAMEPLATE LOCATED ON THE FRAME.
ENSURE THAT TURNTABLE LOCK IS ENGAGED BEFORE BEGINNING ANY EXTENDED
TRAVELING. AVOID ANY TERRAIN FEATURES WHICH COULD CAUSE THE MACHINE TO
UPSET.
DRIVE SPEED/TORQUE SELECT SWITCH SHOULD BE IN THE BACKWARD POSITION FOR:
• TRAVELING GRADES
• TRAVELING IN DIFFICULT CONDITIONS
• SHARP TURNS (ESPECIALLY WITH ONE TRACK STOPPED
• COUNTERROTATION
USE EXTREME CAUTION WHEN DRIVING IN REVERSE AND AT ALL TIMES WHEN DRIV-
ING WITH THE PLATFORM ELEVATED AND SPECIALLY WHEN DRIVING WITH ANY PART
OF THE MACHINE WITHIN 6 FEET (2M) OF AN OBSTRUCTION. DO NOT USE DRIVE TO
MANEUVER PLATFORM CLOSE TO AN OBSTRUCTION. USE ONE OF THE BOOM FUNC-
TIONS.
USE EXTREME CAUTION WHEN APPROACHING A CREST OF ANY TERRAIN OBSTACLE.
CHECK FOR CURBS, LARGE STONES, OR OTHER TERRAIN OBSTACLES INCLUDING
OVERHEAD OBSTACLES AS THE MACHINE WILL MAKE UNCONTROLLED PIVOTING
MOTIONS WHEN THE CENTER OF GRAVITY (CENTER OF TRACK FRAME) SHIFTS OVER
AN EDGE. SLOW DOWN TO MINIMIZE ACCELERATION DURING PIVOTING MOVEMENT.
BEFORE DRIVING, MAKE SURE THE BOOM IS POSITIONED OVER THE REAR OF THE
CHASSIS (OVER FINAL DRIVES AND SPROCKETS). IF THE BOOM IS OVER THE FRONT OF
THE CHASSIS (OVER THE IDLER WHEELS) STEER AND DRIVE CONTROLS WILL MOVE IN
OPPOSITE DIRECTIONS TO MACHINE CONTROLS.
Traveling Forward or Reverse
