Replace the carbon brushes as directed. Carbon Brush Replacement Hours Propel Motor 750 Vacuum Motors Brush Motors 1000 WARNING: Electrical Hazard. Disconnect Battery Cables Before Servicing Machine. BATTERY MAINTENANCE WARNING: Fire Or Explosion Hazard. Batteries Emit Hydrogen Gas. Keep Sparks And Open Flame Away. Keep Battery Compartment Open When Charging. FOR SAFETY: When servicing batteries, wear protective gloves and eye protection. Avoid contact with battery acid. To prolong the life of the batteries only recharge the batteries if the machine is used for a total of 30 minutes or more. Never leave batteries discharged for lengthy periods. 1. Check battery fluid levels before and after charging. The fluid should be at the level shown (Figure 62). Add distilled water if low. DO NOT OVERFILL. The fluid will expand and may overflow when charging. FIG. 61 FOR SAFETY: When servicing machine, disconnect the battery connections. 7. Clean the batteries and check the fluid levels (See BATTERY MAINTENANCE). 8. Check for loose or worn battery cables. Replace if worn. 9. Lubricate all pivot points with a water resistant grease. 10.

Before Charging After Charging Fluid level slightly above battery plates Fluid level slightly below sight tubes FIG. 62 12 R14 1032129 REV.01 (12-06) 2. Clean the batteries and terminals to prevent battery corrosion. Use a scrub brush with a mixture of baking soda and water (Figure 63). ATTENTION: Do not allow the baking soda solution to enter the batteries. MACHINE JACKING Use the designated jacking locations for jacking up the machine (Figure 65). Empty the recovery and solution tanks before jacking. Use a jack capable of supporting the weight of the machine. Position the machine on a flat, level surface and block the tires before jacking. FOR SAFETY: When servicing machine, jack machine up at designated locations only. Use jack or hoist that will support machine weight. Block machine up with jack stands. FIG. 63 3. Check for loose or worn battery cables. Replace if worn. PRIMING SOLUTION SYSTEM To prime the machine’s solution system, operate the ReadySpace technology for approximately one minute (Figure 64). Once primed, the machine can be used for restorative extraction cleaning. If the solution system is completely dry or if you notice center streaking when restorative extraction cleaning, the solution system must be primed. FIG. 65 PUSHING, TOWING, AND TRANSPORTING MACHINE PUSHING OR TOWING THE MACHINE Before attempting to push or tow the machine, the brake must be disengaged. To disengage the brake, insert a small standard screwdriver between the electronic brake lever and the hub (Figure 66). FOR SAFETY: When brake is disengaged, do not push or tow the machine on inclines. FOR SAFETY: When brake is disengaged, do not operate machine. FIG. 64 FIG. 66 R14 1032129 REV.01 (12-06) 13 Only push or tow the machine on a level surface. Do not exceed 2 mph / 3.2 kph. When towing machine, only tow it from the front by the stabilizer arms (U--shape bars). Immediately after pushing or towing the machine, enable the brake. Never operate the machine with the brake disabled. 6. Secure the front and rear of the machine with tie--down straps (Figure 68). Route the front strap through the stabilizer arms (U--shape bars). Route the rear strap above the rear axle at center. It may be necessary to install tie-down brackets to the floor of your trailer or truck. TRANSPORTING THE MACHINE When transporting the machine by use of trailer or truck, carefully follow the loading and tie--down procedures: FOR SAFETY: When transporting machine, go slowly on inclines and slippery surfaces. 1. Empty the solution tank and recovery tank. 2. Raise the scrub head to the up position. 3. Load the machine using a ramp that can support the machine weight and operator. Do not operate the machine on a ramp incline that exceeds an 11° angle (Figure 67). A winch must be used when ramp incline exceeds an 11° angle. FOR SAFETY: When transporting machine, use a ramp that can support the machine weight and operator. Do not operate the machine on a ramp incline that exceeds an 11° angle. Use tie--down straps to secure machine to truck or trailer. FIG. 68 NOTE: When transporting machine in freezing temperatures see STORING MACHINE, step 5. STORING MACHINE 1. Charge the batteries before storing. Never store machine with discharged batteries. 2. Drain and rinse the tanks thoroughly. 3. Park the machine in a dry area with the scrub head in the raised position. 4. Open the recovery tank cover to promote air circulation. 11° maximum ramp angle FIG. 67 4. Once loaded, position the front of the machine up against the front of the trailer or truck. Lower the scrub head and turn the key off (Figure 68). 5. Place a block behind each wheel (Figure 68). 5. If storing machine in freezing temperatures be certain to drain tanks, purge pump and remove the solution tank filter located under the machine at rear. ATTENTION: Do not expose machine to rain, store indoors. RECOMMENDED STOCK ITEMS Refer to the Parts List Manual for recommended stock items.
