WRONG WA'_/ WAY Figure 7 EN@ NE INF@RMATMON A= FU_L,gNG YOUR UNI;T (See "Specifications, 4. DO NOT USE: 1. FUEL MIXTURE o Your unit is powered by a 2-cycle engine which requires a fuel mixture of regular, unleaded gasoline and a high quality engine oil specially made for 2-cycle, air-cooled engines, The internal design of the 2-cycle engine requireslubrication of moving parts Lubrication is provided when you use the recommended mixtureof gasolineand oil. • Gasoline must be clean and not over two months old. After a short period of time, gasoline begins to chemically break down and willform compounds that can cause hard starting and damage in 2-cycle engines o The correct measure of gasolinetoeilisveryimportant. Too much oil will foul the spark plug. Toolittle oil will cause the engine tooverheat and freeze up • Always mix the fuel thoroughly in a container since gasoline and oil do not readily combine. Do not try to mix fuel directly in the fuel tank 2_ page 2, for location of Fuel Cap.) USE THE FOLLOWING: ° BIA OIL (Boating Institute of America) --- Does not have proper additives for air-cooled, 2_cycle engines and could cause damage o AUTOMOTIVE OIL ---Does not have proper additives for 2-cycle engines and could cause damage • GASOLINE CONTAINING ALCOHOL (High Test, Premium or Gasohol) ---Stiffens critical carburetor fuel metering eler_ents and causes engine damage from overheating --Increases vapor lock (causes hard starting) -- Attracts water causing corrosion damage 5. IMPORTANT POINTS TO REMEMBER a, Use only recommended 1 GALLON REGULAR UNLF_DED _- -- OR-- _ fuel mixtures. b Eliminate all sources of sparks or flame in the areas where fuel is mixed, poured, or stored. There should be no smoking, open flames or work that can cause sparks. c Use an approved, marked container for all fuel purposes. 3. HOW TO MIX FUEL a Pour one-half of the gasoline into an approved marked container. Do not try to mix fuel directly in the h_el tank. b Add entire measure of 2-cycle Engine OiL c. Mix. d. Add remainder of gasoline. e Mix thoroughly for one mim,te. B, PRE-OPERATBON CHECKS Before operating your unit, always: t. _- CHECK OVER SAFETY RULES AND PRECAUTIONS in this Operator's Manual Make certain you completely understand and follow each one 2. ,-- CHECK THE AIR FILTER. Clean the filter before operating the unit, See Figure 15. d Mix and pour fuel in an outdoor area. Store fuel in a cool, dry, well-ventilated place. Gasoline vapors are harmful to your health and can cause serious hazards,such as explosion and fire Use a funnel or spout when pouring fuel e. Wipe up all fuel spills before starting the engine. f. Move at least 10 feet (3 meters) away from fuel and fueling site before starting the engine. 3. v" CHECK THE UNIT FOR lOOSE BOLTS, NUTS, OR FITTINGS. Tighten, repair or replace parts as necessary. Use only genuine replacement parts; 4. v" CHECK THE FUEL TANK.

CARBURETOR ADJUSTMENTS The carburetor has been carefully adjusted at the factory. Due to changes in altitude and operating conditions, your carburetor may require adjusting. To make the adjustment follow the procedure below very carefully: a PREPARATION 1) Use fresh fuel mix See Fuel Mixture page 7 2) Remove air filter 3) Turn mixture screw clockwise _ until fully closed, but do not overtighteno Figure 12 Unscrew mixture screw one full turn counterclockwise 4) Turn Idle Speed Screw clockwise ==,=-_ until it stops Do not overtighten. Open screw three full turns counterclockwise / IDLE SPEED ADJUSTMEN1 b IDLE SPEED ADJUSTMENT 1) Start the engine and turn throttle control to halfway between "Fast" and "Slow" 2 ) Operate the unit for 3 minutes to warm up engine 3) Turn throttle control counterclockwise to slow setting 4) Adjust Idle Speed Screw: Clockwise _ if the engine stalls: Counterclockwise _ to slow engine down 5 ) Adjust the Idle Speed Screw until the engine idles as slow as possible without the engine stalling t CAUTION:] The mixture setting is a highly critical adjustment. If set incorrectly, permanent damage will occur to the engine. Do not operate engine at fast throttle fdr prolonged periods while making the mixture adjustment. c MIXTURE ADJUSTMENT: 1) Adjust throttle knob to "Fast" position 2 ) Turn the Mixture Screw slowly clockwise until the engine speed is reduced Note position 3) Turn the screw slowly counterclockwise _===_ Stop when the engine just begins to run rough 4) Turn the screw slowly the minimum amount clockwise ==="_ until the engine runs smoothly NOTE 1: The mixture screw should be in the range of 3/4 to 1-1/4 turns open NOTE 2: For the best engine performance, it is better to run a slightly rich mixture setting (counterclockwise _ )than too lean a setting d REPLACE AIR FILTER 2.

Before starting the engine and during operation make certain people and animals are away from the work area - a minimum of 30 feet (10 meters). 7 Check air intake opening and collection bag tube frequently, always with the engine stopped. Engine RPM will increase significantly when the suction or collection bag tube is clogged. Keep vents and tubes free of debris which can accumulate and restrict proper air flow.

(Figure 14) Do not overreach or use from unstable surfaces such as ladders, trees, steep slopes, roof tops, etc Keep firm footing and balance at all times 9 Do not wear rubber or any other insulated gloves to avoid static electricity shock. Figure 14 B. OP_RATnNG T_PS 1, Move the unit slowly back and forth over debris to be vacuumed, Avoid forcing the suction tube into a pile of debris as this can clog the unit. 2 If the unit becomes a. b c clogged: Stoptheengineanddisconnectthesparkplug.Do not attempt to remove obstructions with engine running. Wait until the impetler has completely stopped turning, then remove the suction tube Carefully reach into the vacuum opening and clear out debris 3 The collection bag must be properly emptied ,and maintained to avoid deterioration a nd obstructing air flow which will reduce the performance of the vacuum. a. Empty the bag after each use. Do not store bag containing wet grass, leaves, etc b. Clean the bag after every three uses by turning the bag inside out after initial emptying and vigorously shaking out dust and excess debris c. Wash the bag once a year 1) Turn bag inside out 2). Hang up 3). Hose down thoroughly 4). Hang to dry 11 MA NTENAN©E Ao AIR FILTER CARE A dirty air filter decreases engine performance and increases fuel consumption_ Clean the Air Filter: • Frequently, o Always clean after 5 tanks of fuel or 5 hours of operation, whichever is less. Follow these steps: 1 Remove the air filter (located above the control panel; see Figure 15) 2 Wash in soap and water I CAUTION:I Do not clean filter in gasoline or other flammable solvent to avoid creating a fire hazard. & Squeeze filter dry 4 Add a small amount of oil to coat the filter, NOTE: Avoid soaking the filter with oil 5 Squeeze out excess oil 6 Replace the air filter. NOTE: Make sure the filter is properly fitted into the housing, paying particular attention to the corners. Bo FUEL TANK UPKEEP Never use gasoline that is more than 2 months old in a fuel mixture. Gasoline begins to break down after a short period of time and will form compounds that cause hard starting and damage in 2-cycle engines Figure 15 1 Inspect the unit for fuel leaks each time it is used. Repair or replace parts as necessary 2 Always begin operation with a clean, fresh mixture of fuel. 3 Drain all fuel from the unit or allow unit to run out of fuel before storing for 30 or more days.
