Emission Control (Exhaust & Evaporative) EPA 2010 and Later and/or C.A.R.B. TIER III The emission control system for the engine is EM/TWC (Engine Modification and 3-way Catalyst) and for the fuel tank the Control System is EVAP (Evaporative Emissions) or N (for nylon tank). Evaporative emission may be applicable to California models only. An Emission Control Label is located on the unit. (This is an EXAMPLE ONLY; information on label varies by engine FAMILY).
Assembly (continued) Adjust Throttle Trigger Free Play Loosen the air cleaner cover knobs The throttle trigger free play should be approximately 3/16-1/4 inch (4-6 mm). Make sure that the throttle trigger operates smoothly without binding. If it becomes necessary to adjust the trigger free play, follow the procedures and illustrations that follow. 1. Loosen the air cleaner cover knobs and remove the air cleaner cover. 2. Loosen the lock nut on the cable adjuster. 3.
Assembly (continued) 1. Push one of the drum axles onto either of the two gearcase output shafts. If necessary, rotate the drum axle until the clevis pin hole in the axle aligns with the matching hole in the gearcase output shaft. CAUTION! The two drum assemblies are identical, but each drum must be installed with its recessed end facing toward the gearcase. 2. Use a clevis pin and hitch pin to secure the drum axle to the shaft. 3.
Handling Fuel DANGER Fuel is VERY flammable. Use extreme care when mixing, storing or handling or serious personal injury may result. • Use an approved fuel container. • DO NOT smoke near fuel. • DO NOT allow flames or sparks near fuel. • Fuel tanks/cans may be under pressure. Always loosen fuel caps slowly allowing pressure to equalize. • NEVER refuel a unit when the engine is HOT or RUNNING! • DO NOT fill fuel tanks indoors. ALWAYS fill fuel tanks outdoors over bare ground. • DO NOT overfill fuel tank.
Starting the Engine IMPORTANT Engine ignition is controlled by a two position switch mounted on the throttle housing labeled, “I” for ON or START and “O” for OFF or STOP. WARNING! The attachment will operate immediately when the engine starts and could result in possible serious injury. Keep movable parts of the attachment away from objects that could become entangled or thrown, and surfaces that could cause loss of control. WARNING! Never start the engine from the operating position. 1.
Starting the Engine (continued) When the Engine Starts... ■■After the engine starts, allow the engine to warm up at idle 2 or 3 minutes before operating the unit. ■■If the engine does not continue to run, repeat the appropriate cranking procedures for a cold or warm engine.When the engine starts, clear excess fuel from the combustion chamber by accelerating the engine several times with the throttle trigger.
Operating Break-in and Operation The PowerBroom works best when its rubber fins can quickly slide or “skim” over the surface being swept. New or replacement sweeper belts tend to grip or drag on hard surfaces, and should be thoroughly broken in or “scuffed” before the broom is actually put to work. Break-in is easily accomplished by operating the PowerBroom at full throttle for 3 to 5 minutes in loose gravel or similar abrasive material.
