Direct Drive Installation and Setup Unpacking A factory trained COATS Service Technician must perform the install, setup, and initial test procedures on your 6401 balancer. Do not attempt to install and setup the unit yourself. Accurate and reliable operation of your unit depends on proper installation. Please contact COATS® directly at 1-800-688-9240 for the Certified Service Partner nearest you.
Direct Drive Install and tighten the four (4) remaining accessory pegs and hang the accessories. Note: Balancer will not operate properly on pallet. Hood and Pod Set-up To set up hood: Locate hood stop in accessory box and install as shown. Install hood spring as shown. Do not install hood spring until Control Pod has been set up. Control Pod Setup: Carefully hold control Pod and Post while removing 4 retaining screws. Swing Pod upright as shown above and tightly reinstall the 4 screws.
Direct Drive Electrical Power Consult a licensed electrical contractor for proper installation to local electrical codes. Power outlets must be enclosed in a floor raceway or overhead drop if predestrian or equipment traffic can damage existing power cord. To Outlet Ground X Y Green Z CAUTION Operation with a defective ground circuit will create a shock hazard for the operator and could damage the balancers electronics. Operation with a defective ground circuit may void warranty.
Direct Drive Initial Testing Initial testing and training are provided by your COATS distributor. Complete instructions for unpacking and installIng your balancer are contained in the INSTALLATION AND SETUP section of this manual. Precautions: Initial testing should be performed by instructor. Power requirements must be verified by installer or instructor before connecting balancer. Failure to observe this precaution may void warranty. Power: Plug power cable into power outlet receptacle.
Direct Drive Balancing Procedure Display Board Layout 1. Start button 2. INNER weight display. 3. INNER position display. 4. OUTER position display. 5. OUTER weight display. 6. STATIC balance button. 7. “MAG” balance button. 8. Wheel diameter (D) knob. 9. Wheel width (W) knob. 10. Wheel offset (A) knob. Leave balancer power on all day. Static power use is approximately 70 watts. 1. Mount Wheel Select proper adapter. Adapter selected should center wheel the same as the wheel is centered on the vehicle.
Direct Drive 2. Offset Enter offset distance with this knob. Move distance gauge to touch edge of wheel. Enter this distance measurement with offset (A) knob. (Shown in Fig. 1). MAG Wheels Setup for hidden weights on “mag” is the same as for standard wheels.
Direct Drive 3. Rim Width Enter wheel width information with this knob. Use rim width calipers to measure wheel at points shown. MAG Wheels Setup for hidden weights on “mag” wheels is the same as for standard wheels. Enter this width reading with the width (W) knob. (Shown in Fig. 1).
Direct Drive 4. Rim Diameter Enter rim diameter size as read from tire sidewall. Setup for hidden weights on “mag” wheels is the same as for standard wheels. Enter this diameter reading with the diameter (D) knob. (Shown in Fig. 1).
Direct Drive 5. Spin Mode CAUTION Lower Guard Hood Before Starting Spin. Press start button to obtain normal readings. Balancer will spin and stop automatically. 6. Take Readings Weight and position readings will appear on displays as balancer is braking tire. FINE BALANCE (for unbalance of 0.2 ounce or less): hold button down during spin cycle. Position readings will always appear. (Not needed in normal use.) 7. Attach Weight 1. Rotate wheel until right (OUTER) twin lights blink alternately. 2.
Direct Drive Balancing Special MAG Wheels (Adhesive Weights) Read weight amount and locate position as with a “standard” wheel. If standard clip weights are to be used, balance as a “standard” wheel. The mag button is used when some specialty wheels are to be balanced or when adhesive weights are required (i.e., hidden weight method). Lower hood. Push appropriate button and check weight application. Raise hood. Apply required weights.
Direct Drive 2. Standard Clip Weight One Adhesive Weight (Hidden Method) MAG Use Mag Button. Enter rim diameter as read from the sidewall. Move distance gauge arm to touch inner edge of wheel. Enter distance gauge reading. Read INNER weight amount and locate position for inner plane. Standard clip weight will be placed here. OUTER adhesive weight will be applied here. Read OUTER weight amount and locate position for outer plane, Install weight as described on page above.
Direct Drive Static Balancing (Adhesive Weight) Note: This method should only be used when the customer requests no visible weights (outer plane) and there is a caliper clearance problem on the inner plane. Since rim diameter is slightly smaller than tire size “D” enter one inch smaller than tire size. STATIC Use Static Button. Adhesive weight will be applied here.
Direct Drive Wheel Mounting Options Back Cone Mounting 1. Place spring over threaded stud with the large end inside of the faceplate. 2. Select a cone that best fits into wheel center hole. 3. Slide selected cone onto threaded shaft with the large end against the spring. Light Truck Cone CAUTION Cone must be centered in wheel center hole before tightening. Thread hubnut on and tighten by rotating wheel and striking both arms of hubnut with palm of hand. 4. Lift wheel onto shaft and center on cone.
Direct Drive Special Problems Customers will occasionally complain of vibration on the car after balancing. Some possible causes are listed below: 1. Beads improperly seated. Check bead seating and inflation pressure before balancing spin. 2. Stiffness variations in radial belts. 3. Tire out of round; wheel out of round, bent, or not running true. Visually check runout of wheel and tire during balance spin. Re-check mounting. Replace wheel or tire if necessary. 4.
Direct Drive Calibration Adjustment Procedure Note: Do not preform Calibration Adjustment when motor is excessively hot. 9. Adjust the inner weight trimpot (affects inner magnitude) until display reads 4 ounce (113 gram). Use the same procedure as in Step 7. The outer weight reading should be .21 ounce (6 gram) or less. Set the service switch to the bottom position (NORM). 10. Calibration is now complete.
Direct Drive Optional Combi Adapter Preventative Maintenance CAUTION DO NOT use a solvent which leaves an oil residue. CAUTION Daily: Clean shaft and faceplate with a vaporizing solvent. Cones, hubnut and other mounting hardware should be checked/cleaned at this time. Monthly: Clean entire machine. Remove all used weights, tools and parts which may be under, or leaning against balancer. Perform Calibration Check Procedure. Make adjustments only if required.
