Thereafter, check them every 30 hours. 3. Check Drive Belt Tension. Due to belt seating, a tension adjustment may be needed after the first 2-to-3 hours of new operation. Thereafter, check belt tension every 10 operating hours. 4. Check Hardware. After 2 hours of new operation, check for loose bolts and nuts. Thereafter, do this every 10 operating hours. Preparation Before Starting Make the following checks and perform the following services before starting the engine. 1. Check Engine Oil Level. 2. Check the Air Cleaner. It must be securely assembled and clean. 3. Check Safety Guards. All guards and covers must be securely in place. 4. Attach Spark Plug Wire. 5. Check Engine Cooling System. The cooling fins and air intake screen must be clear of debris. 6. Adjust Handlebar Height. 7. Check Battery Fluid Level. Cells must be filled to proper level, cell caps must be tight, and all electric wire connections secure. 8. Add Gasoline to Fuel Tank. Use fresh, clean, lead-free automotive gasoline. A minimum of 77 octane is recommended. DO NOT MIX OIL WITH GASOLINE! Refer to the separate Engine Owner’s Manual for detailed fuel recommendations. Note: The use of gasoline which contains alcohol, such as gasohol, is not recommended. However, if gasoline with alcohol is used, it must contain less than 10% Ethanol and must be removed from the engine during storage. Do not use gasoline which contains Methanol. Purchase fuel in a quantity that can be used within 30 days. This will assure fuel freshness and volatility tailored to the season. The use of a fuel stabilizer additive will prevent gum from forming in the fuel system or on essential carburetor parts. See the “Storage Instructions” in the Engine Owner’s Manual. To Add Gasoline: a. Clean the fuel cap area before removing the fuel cap. b. Using a clean funnel, fill tank to within 1/2" of the top to prevent spills and to allow for fuel expansion. Replace the fuel cap securely before starting the engine. A DANGER Gasoline is highly flammable and its vapors are explosive. Follow these safety practices to prevent injury from fire or explosion: • Never fill tank if engine is running or hot from use. Let engine and muffler cool down before refueling. • Do not permit open flames, sparks, matches or smoking in the fueling area. • Fill fuel tank outdoors in a well-ventilated area. Wipe up any fuel spills and move tiller away from fumes before starting the engine. I* Use only an approved fuel container and lock it safely away from children. • Store fuel and the tiller in a well-ventilated area. Do not store fuel or tiller where fuel vapors may reach an open flame or spark, or an ignition source (a hot water heater, furnace, clothes dryer, electric motor, or the like). • Let engine cool before storing. • Never bring a metal fuel can near battery post on electric start model tillers. An electrical short circuit could result, causing an explosion of the gasoline or of battery gases. 25 Test Operation of Forward Interlock Safety System The Forward Interlock Safety System is designed to shut the tiller engine off immediately if you loose control of the tiller and cannot stop forward motion by moving the Wheels/Tines/PTO Drive Lever into NEUTRAL. Simply, it is an electrical grounding system that connects the two Forward Interlock Levers on the handlebars to the engine’s ignition system. Either one (or both) of the Forward Interlock Levers must be kept squeezed against the handlebar grip(s) whenever the Wheels/ Tines/ PTO Drive Lever is engaged in FORWARD. If you release both the Forward Interlock Lever(s) before first moving the Wheels/Tines/PTO Drive Lever to NEUTRAL, the interlock system will ground out the engine’s ignition system and stop the engine. (The interlock system also prevents the engine from starting if the Wheels/ Tines/PTO Drive Lever is engaged in FORWARD.) This system has an electro-mechanical design, and so is subject to normal wear and possible malfunction. As such, it must be checked for proper operation before you use the tiller or PTO power unit each time. A danger The Forward Interlock Safety System is designed for the operator’s safety. Do not disconnect or attempt to defeat the purpose of the system. If the system malfunctions, immediately contact your local authorized dealer or the Factory Technical Service Department for assistance. Do not use the tiller or the PTO power unit until the Forward Interlock Safety System is functioning properly. Always test the system before using the tiller or PTO power unit. How to Check the Interlock System: 1. Move tiller outside on level ground. Remove any obstacles. 2. Check that the Forward Interlock wire harness plug at the bottom of the handlebars is firmly connected to the receptacle on the top, right side of the transmission. See Photo 4-2. Photo 4-2: Plug and receptacle of Forward Interlock Safety System must be securely connected. 3. Move Wheel Speed Lever to SLOW posi...
