2 Danger In certain conditions, gasoline is extremely flammable and highly explosive. A fire or explosion from gasoline can burn you and others and can damage property. 1 • Fill the fuel tank outdoors, in an open area, when the engine is cold. Wipe up any gasoline that spills. • Do not fill the fuel tank completely full. Add gasoline to the fuel tank until the level is 1 in. (25 mm) below the bottom of the filler neck. This empty space in the tank allows gasoline to expand.
Transport Hooks 2. Position a spring scale on transport hook and lift up. Tension necessary to lift gauge wheel off ground should be 30–50 lbs. 1. Lift each end of reel and remove transport hooks before operating machine. 3. If tension is not 30–50 lbs., adjustment is made by tightening or loosening adjustment screw on counterbalance spring. 4. Perform this procedure on both sides of sweeper. 1 Note: Because of added weight of drive components, the R.H. spring will require a tighter setting than the L.
4. Repeat procedure on opposite side of machine. Operation 5. Retighten adjustment lock nut. Note: Determine the left and right sides of the machine from the normal operating position. Adjust Rubber Flap For best debris pick up results, metal portion of front flap should be vertical to ground. Controls 1. Move flat lever forward to lower flat. Flap Lever Move flap lever (Fig. 15) downward to engaged position and upward for disengaged position. Move lever to upward position when transporting machine.
Throttle Control Throttle (Fig. 17) is used to operate engine at various speeds. Moving throttle lever to FAST position increases engine speed. To decrease engine speed, move lever to SLOW position (Model 07050 only). 1 Tailgate Latch Rope Pull tailgate latch rope (Fig. 18) to unlatch tailgate when emptying hopper. Figure 16 1. Clutch handle 2 1 Choke Control To start a cold engine, close carburetor choke by moving choke control lever (Fig. 17) to the “ON” position.
Stopping Instructions Important Do not operate sweeper while reel is turning and in the raised position. Damage to the rake and tires may result if teeth come in contact with tires. 1. Disengage power to rake by disengaging clutch lever. 2. Move throttle lever to “SLOW” position. Caution 3. Move ignition switch to “OFF” position. Remove key from switch to prevent accidental starting. This product may exceed noise levels of 85 dB(A) at the operator position.
Maintenance Note: Determine the left and right sides of the machine from the normal operating position. Important Refer to your engine operator’s manual for additional maintenance procedures. Lubrication The Rake–O–Vac has grease fittings that must be lubricated regularly with No. 2 General Purpose Lithium Base Grease. Lubricate bearings after every 30 hours of operation or whenever machine is washed with water.
Changing Engine Oil and Filter (Model 07050 only) Change oil initially after the first 5 hours of operation, thereafter change oil every 100 hours and filter every 200 hours. 1. Park the machine on a level surface and turn the engine off. 2. Remove drain plug and let oil flow into drain pan. When oil stops, install drain plug. Note: Warm oil flows better and carries more contaminants than cold oil. 3. Remove oil filter. Apply a light coat of clean oil to the new filter gasket.
General Air Cleaner Maintenance 4. Blow compressed air from inside to the outside of dry filter element. Do not exceed 100 psi to prevent damage to the element. (Model 07050 only) 5. Keep air hose nozzle at least 2” from filter and move nozzle up and down while rotating the filter element. Inspect for holes and tears by looking through the filter toward a bright light. • Check air cleaner body for damage which could possibly cause an air leak. Replace a damaged air cleaner body. 6.
Important A cracked, fouled, dirty or otherwise malfunctioning spark plug must be replaced. Do not sand blast, scrape, or clean electrodes by using a wire brush because grit may eventually release from the plug and fall into the cylinder. The result is usually a damaged engine.
