INTAKE HOSE: Hose mounting assembly must be properly attached to vac housing and safety switch must be engaged before engine will start. Note: Any damage to the switch or wiring harness will prevent engine from starting. CHOKE: Located on the vac housing as part of the engine control panel. THROTTLE: Move throttle control to fast position. KEY SWITCH: Turn to start position until engine begins to fire, immediately release the key to the run position. Note: Do not hold key in start position more than 10 seconds per attempt. IF YOUR UNIT FAILS TO START: See Troubleshooting on page 12. Also see engine owner's manual. PUT OIL IN ENGINE BEFORE STARTING. Page 6 of 12 OPERATION continued HOSE CARE & USE TIPS Be sure the hose is correctly installed by checking that the arrow printed on the hose indicating flow direction is pointing toward the vac housing. Keep hose as straight as possible and avoid sharp bends during operation for best pick-up and to avoid clogs. Never drag hose. Always remove and store hose before transporting unit. Store hose straight and flat to maintain flexibility for next use. To increase hose life, periodically rotate hose and reposition nozzle and coupler on front plate of unit. This increases hose life by keeping hose from wearing only on one side. THE HOSE IS A REPLACEABLE WEAR ITEM. FOR BEST HOSE OPERATION RESULTS, FOLLOW THESE RECOMMENDATIONS. INTAKE OPERATION: With machine running and fully assembled, move the nozzle in sweeping motions over debris. Always allow air to flow into the nozzle along with the debris. Do not completely block the nozzle when vacuuming, it will reduce performance, and increase clogging (See figure 3). For removal of heavier debris, or debris that is stuck to the ground, rock nozzle forward to concentrate suction power around the debris (See figure 4). Fig. 3 Fig. 4 Inspect machine work area and machine before operating. Make sure that all operators of this equipment are trained in general machine use and safety. STARTING EXHAUST DIRECTION & DISTANCE: Exhaust direction and distance are controlled by the angle of the exhaust deflector and by rotation of the exhaust elbow. Adjust the angle of the exhaust deflector to control the distance that debris is discharged. Typically debris is aimed to discharge to the rear of the container. The direction of discharge is adjusted by loosening the knobs on the exhaust elbow clamp and rotating the elbow to the desired direction. NOTE: Elbow is heavy. Use caution when adjusting. Never stand directly under the elbow while adjusting direction of exhaust. Never adjust exhaust deflector angle or direction of discharge while unit is running. Never direct exhaust into an area where bystanders may cross the path of the debris. OPERATION KEEP ENGINE CLEAN OF DEBRIS DO NOT OPERATE UNLESS DEBRIS IS DISCHARGING INTO AN ENCLOSED CONTAINER OPERATION continued ADJUSTING HOSE BOOM: Properly adjusting the boom will prevent most hose clogs from occurring and will maximize vacuum performance by keeping the hose straight and perpendicular to the housing (see fig. 5). Hose Bands. Hose Stretch hose out before clamping. Fig. 5 UNCLOGGING A CLOGGED HOSE: With engine running and unit secured to a trailer, truck bed, or other similar surface, fully stretch hose in a straight line to dislodge the clog. If the clog will not clear, turn unit off, and allow engine to come to a complete stop. Remove hose and manually clear hose clog. NOTE: The clogged debris may be sharp. Always wear durable gloves when removing clog. UNCLOGGING A CLOGGED HOUSING OR EXHAUST ELBOW: Turn engine off and wait for impeller to come to a complete stop. Disconnect spark plug wires and battery cables. Remove the hose coupler from the housing and determine where the clog is located. If possible clear the clog through the intake opening. It may require removal of the intake adaptor (item 33) to allow access to clear the housing. If clog is in the elbow, carefully remove the elbow. Remove elbow by removing the knobs on the elbow clamp. Then remove 3 bolts so that the split plate can be taken out. FInally, the elbow can be removed by sliding it past the remaining attached clamp. NOTE: Elbow is very heavy. Do not stand directly under elbow during removal. Danger, the clog may contain sharp materials. Wearing durable gloves, clear the clog. Reconnect spark plug wire. HANDLING & TRANSPORTING The unit is equipped with small front wheels to allow for easier transportation to storage. With unit removed from its mounting, tilt unit forward toward the ground and use wheels to manuever it into storage area. STORAGE Drain all fuel prior to storage. Never store engine indoors or in enclosed poorly ventilated areas with fuel in tank, where fuel fumes may reach an open flame, spark or pilot light, as on a furnace, water heater, clothes dryer or other gas appliance. If engine is to be unused for 30 days or more, prepare as follows: Be sure engine is cool. Do not smoke. Remove all gasoline from carb...
