9 WARNING For the protection of the environment; when servicing any of the machine s lubrication fl uids they must be disposed of safely in accordance with your local environmental regulations (recycling). Examples of machine lubrication products: (Hydraulic system oil, Hydraulic system oil filter). HOPPER DUST CONTROL FILTER The hopper dust control fi lter must be cleaned regularly to maintain the effi ciency of the vacuum system. Follow the recommended fi lter service intervals for the longest fi lter life. CAUTION! Wear safety glasses when cleaning the fi lter. Do t puncture the paper fi lter. Clean the fi lter in a well-ventilated area. To remove the hopper dust control filter... 1 Lift the Hopper Cover (16) on top of the hopper. Make sure that the Hopper Cover Prop Rod (9) is in place. 2 Inspect the top of the Hopper Dust Control Filter (17) for damage. A large amount of dust on top of the fi lter is usually caused by a hole in the fi lter or a damaged fi lter gasket. 3 Turn the two hold-downs to the side (one on each side at the front of the frame) to release the shaker frame, then swing the Dust Filter Shaker Assembly (18) up and latch in place with the Shaker Assembly Latch (19). 4 Lift the Hopper Dust Control Filter (17) out of the machine. 5 Clean the filter using one of the methods below: Method A Vacuum loose dust from the fi lter. Then gently tap the fi lter against a fl at surface (with the dirty side down) to remove loose dust and dirt. NOTE: Take care t to damage the metal lip which extends past the gasket. Method B Vacuum loose dust from the fi lter. Then blow compressed air (maximum pressure 100 psi) into the clean side of the fi lter (in the opposite direction of the airfl ow). Method C Vacuum loose dust from the fi lter. Then soak the fi lter in warm water for 15 minutes, and then rinse it under a gentle stream of water (maximum pressure 40 psi). Let the fi lter dry completely before putting it back into the machine. 6 Follow the instructions in reverse order to install the fi lter. If the gasket on the fi lter is torn or missing, it must be replaced. FIGURE 1 MAINTENANCE HYDRAULIC OIL Raise and prop (HH) the hopper. See Figure 1. The oil level should be approximately 1 inch (2.54cm) below the bottom of the Elbow (A) on the front of the reservoir when the hopper is up (when the hopper is fully down the oil level should be up to the bottom of the elbow). If it is below this level, add 10W30 motor oil. Change the oil if major contamination from a mechanical failure occurs. SERVICE NOTE: The Cap (B) on Elbow (A) on the side of the reservoir is for adding oil. SERVICE NOTE: Remove Vent Plug (D) to allow oil to be fi lled. IMPORTANT! This machine is equipped with an Indicator Light (F) which lights if the Hydraulic Oil Filter (C / Figure 1) requires changing.

20 KNOW YOUR MACHINE IMPORTANT SERVICE TIP Before any troubleshooting is done perform this troubleshooting special control system procedure. MAIN CONTROLLER (A1) SELF-DIAGNOSTIC TEST MODE If problems with the main electronic control system are suspected, this self-diagstic mode may help isolate the problem. When this mode is activated, the control unit will activate each one of the outputs in sequence and test for short circuits, open circuits, or overload conditions. This mode will also provide an easy test for the touch panel switches and indicators. If an abrmal condition is encountered with one of the outputs, an error code will be displayed on the Scrub Pressure Display (J) see Figure 2. 1 During this test, the horn will sound briefl y and the scrub deck and squeegee will move if they are in the up position. If the hopper is t in the down position it will also move slightly. CAUTION! Make sure that all persons are away from these parts of the machine to prevent injury. 2 Turn the main power key switch to the off position. 3 Press and hold the side broom down/on switch. 4 While holding the side broom down/on switch, turn the main power key switch to the on position. 5 Continue to hold the side broom down/on switch until all indicators except the side broom down/on indicator turn off (approximately two seconds). 6 Release the side broom down/on switch. 7 The control will w activate each output in sequence and perform the tests mentioned above. 8 If abrmal conditions are detected, the display will w show -. Go to step If abrmal output conditions were detected, the display will w show the error code(s), see Main Control Error Code Display Descriptions Table. An example of how two codes, 6 and 18, would be displayed is as follows: The display will show E followed by a brief blank period The display will show 0 followed by a brief blank period The display will show 6 followed by a slightly longer blank period The display will show E followed by a brief blank period The display will show 1 followed by a brief blank period The display will show 8 followed by a long blank period The above sequence will repeat 10 To test any of the control panel switches, press the desired switch.
