Thevibratory system is activated with aswitch on the top of the propel lever.When the vibratory system is activated,a vibration indicator light illuminates.The engine throttle lever is located onthe left side of the control consolepedestal. If equipped with optional lightpackages, switches and a turn signallight are located on the control console.The machine is protected fromvandalism with several covers.The control console, hood andcompartment for the Operation andMaintenance Manual are equippedwith lockable covers.BrakesBrake systems meet SAE J1472,ISO 3450 and EN500-4.Service■ Closed-loop hydrostatic drive systemprovides dynamic braking duringmachine operation.Secondary and Parking■ A spring-applied, pressure-releasedbrake inside each propel motorimmobilizes the roller. Activation isby a switch on the operator’s consoleor when the engine is shut off.Final Drives<strong>CB</strong>-<strong>214D</strong> and <strong>CB</strong>-<strong>224D</strong> – High-torque,low-speed hydraulic motors directlydrive each drum.<strong>CB</strong>-<strong>225D</strong> – High-torque, low-speedhydraulic motor directly drives the frontdrum, and two high-torque, low-speedhydraulic motors directly drive the rearwheels.SteeringAn engine-driven gear-type pumpsupplies hydraulic fluid for the steeringcircuit.Minimum turning radius<strong>CB</strong>-<strong>214D</strong>Inside drum edge 2510 mmOutside drum edge 3510 mm<strong>CB</strong>-<strong>224D</strong>/<strong>CB</strong>-<strong>225D</strong>Inside drum edge 2410 mmOutside drum edge 3610 mmSteering angle32˚Hydraulic system: One 70 mm bore,double-acting cylinder powered by agear-type pump.Output at 2.800 rpm is 23 liter/min withrelief valve at 117 bar.8<strong>CB</strong>-<strong>214D</strong>, <strong>CB</strong>-<strong>224D</strong> and <strong>CB</strong>-<strong>225D</strong> specifications
Electrical SystemSound LevelsWheels and TiresThe 12-volt electrical system includesone maintenance-free Cat battery andcolor-coded and numbered wiringwrapped in nylon braid. The systemincludes a 55-amp alternator.The starting system provides 750 coldcranking amps.Sound level measured at the operatorear (sound pressure) is 80 dB(A), andaverage at spectator (sound pressure)measured at 7 m is 73 dB(A).<strong>CB</strong>-<strong>225D</strong> – 9.5/65-15 6-ply tires arestandard. Each tire is equipped with areplaceable scraper. The scrapers helpclean asphalt or soil off the tires.The scrapers can be positioned abovethe tires when they are not needed.Wheels are on a fixed axle.FrameService Refill CapacitiesTire Wetting SystemFrame is fabricated from heavy gaugesteel plate and joined at the centerarticulation pivot. Two self-aligningbearings on the pivot housing providea ±32 degrees steering angle, and ahorizontal pin provides a ±10 degreesoscillation angle. The articulation pivotis structurally reinforced for extendedservice life. For transport purposes,the articulation pivot can be secured atthe zero steering angle.LitersFuel Tank 36Crankcase 7.1Hydraulic fluid tank 26Hydraulic circuit 30Drum spray system 160Tire wetting system 28Tire Wetting System allows a solvent tobe sprayed on the tire surfaces, helpingprevent asphalt from adhering to thetires. One spray nozzle is positionedabove each tire. The system is controlledwith a momentary switch on the controlconsole.Capacity28 litersWater Spray SystemSpray bars are constructed of stainlesssteel for corrosion resistance. The watertank is reinforced polyethylene.An electric water pump provides eithercontinuous or intermittent spray.Intermittent spray setting increasesspray time by 50 percent overcontinuous setting. Triple filtrationincludes a filter on the tank fill spout,an in-line filter at the water pump andfilters on each spray nozzle. Spraynozzles are easily removed withouttools for cleaning.Capacity160 litersWeightsOperating weights include lubricants, 80 kg operator, full fuel tank, full hydraulicsystem and half-full water tanks (all weights are approximate).<strong>CB</strong>-<strong>214D</strong> <strong>CB</strong>-<strong>224D</strong> <strong>CB</strong>-<strong>225D</strong>Operating without ROPS 2430 kg 2610 kg 2390 kgat front drum 1160 kg 1260 kg 1280 kgat rear drum 1270 kg 1350 kg –at rear wheels – – 1110 kgweight per rear wheel – – 278 kgOperating with ROPS 2490 kg 2670 kg 2450 kgat front drum 1160 kg 1260 kg 1280 kgat rear drum 1330 kg 1410 kg –at rear wheels – – 1170 kgweight per rear wheel – – 292 kg<strong>CB</strong>-<strong>214D</strong>, <strong>CB</strong>-<strong>224D</strong> and <strong>CB</strong>-<strong>225D</strong> specifications 9
