Mixing Fuel WARNING! Alternative fuels, such as E15 (15% ethanol), E-85 (85% ethanol) or any fuels not meeting Shindaiwa requirements are NOT approved for use in Shindaiwa gasoline engines. Use of alternative fuels may cause performance problems, loss of power, overheating, fuel vapor lock, and unintended machine operation, including, but not limited to, improper clutch engagement. Alternative fuels may also cause premature deterioration of fuel lines, gaskets, carburetors and other engine components.
Mixing Instructions 1. Fill an approved fuel container with half of the required 2. 3. 4. amount of gasoline. Add the proper amount of engine oil to gasoline. Close container and shake to mix oil with gasoline. Add remaining gasoline, close fuel container, and remix. IMPORTANT! Spilled fuel is a leading cause of hydrocarbon emissions. Some states may require the use of automatic fuel shutoff containers to reduce fuel spillage. Storage - Fuel storage laws vary by locality.
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. IGNITION SWITCH ON WARNING! Primer Bulb Never start the engine from the operating position. 1. Slide the ignition switch to the “ON” position. 2. Set the throttle lever to the “fast idle”: a. Squeeze the throttle lever toward the handgrip on the shaft tube. b. Depress and hold the throttle lock button. c.
Stopping the Engine Idle the engine briefly before stopping (about 2 minutes), then slide the ignition switch to the “O” (Engine OFF) position. IGNITION SWITCH OFF Adjusting Engine Idle The engine must return to idle speed whenever the throttle lever is released. Idle speed is adjustable, and must be set low enough to permit the engine clutch to disengage the cutting attachment.
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.
Maintenance IMPORTANT! MAINTENANCE, REPLACEMENT OR REPAIR OF EMISSION CONTROL DEVICES AND SYSTEMS MAY BE PERFORMED BY ANY REPAIR ESTABLISHMENT OR INDIVIDUAL; HOWEVER, WARRANTY REPAIRS MUST BE PERFORMED BY A DEALER OR SERVICE CENTER AUTHORIZED BY ECHO, INC. THE USE OF PARTS THAT ARE NOT EQUIVALENT IN PERFORMANCE AND DURABILITY TO AUTHORIZED PARTS MAY IMPAIR THE EFFECTIVENESS OF THE EMISSION CONTROL SYSTEM AND MAY HAVE A BEARING ON THE OUTCOME OF A WARRANTY CLAIM.
Maintenance (continued) 10/15-Hour Maintenance Remove and clean or replace the spark plug. ■■Adjust the spark plug electrode gap to 0.024 0.028 inch (0.6-0.7 mm). If the spark plug must be replaced, use only an Champion CJ8Y or NGK BPMR7A, or equivalent resistor type spark plug of the correct heat range. CAUTION! Before removing the spark plug, clean the area around the plug to prevent dirt and debris from getting into the engine’s internal parts. 0.024–0.028 inch (0.6–0.
Maintenance (continued) 300-hour maintenance Gearcase Lubrication The gearcase should be filled with 60 cc (2.0 fl.oz.) of Mobil SHC634 Synthetic Gear Oil. A maximum of 75-80 cc can be used, but never to exceed 80 cc. Operation with excessive oil level will result in high operating temperatures. Do not overfill! WARNING! BURN DANGER! The gearcase will be extremely hot after use! Replacing the gearcase oil 1. Disconnect spark plug wire at engine. 2.
Maintenance (continued) Muffler Maintenance WARNING! Never operate the unit with a damage or missing muffler or spark arrester! Operating with a missing or damaged spark arrester is a fire hazard and could also damage your hearing. Hard starting or a gradual loss of performance can be caused by carbon deposits lodged in the muffler’s spark arrester screen. In such cases, performance can usually be restored by removing the spark arrester screen and giving it a thorough cleaning with a stiff bristle brush.
