GENERAL INFORMATION
(g) by Belgreen v2.0
Foreword This manual is written for an experienced technician. Essential tools required in performing certain service work are identified in this manual and are recommended for use. Live with safety: Read the safety messages in the introduction of this manual and the cautions presented throughout the text of the manual. CAUTION: This is the safety-alert symbol. When you see this symbol on the machine or in this manual, be alert to the potential for personal injury. Technical manuals are divided in two parts: repair and operation and tests. Repair sections tell how to repair the components. Operation and tests sections help you identify the majority of routine failures quickly. Information is organized in groups for the various components requiring service instruction. At the beginning of each group are summary listings of all applicable essential tools, service equipment and tools, other materials needed to do the job, service parts kits, specifications, wear tolerances, and torque values. Technical Manuals are concise guides for specific machines. They are on-the-job guides containing only the vital information needed for diagnosis, analysis, testing, and repair. Fundamental service information is available from other sources covering basic theory of operation, fundamentals of troubleshooting, general maintenance, and basic type of failures and their causes.

Section 10 - GENERAL INFORMATION
Group 05: Safety
Avoid Fires Handle fuel with care: it is highly flammable. Do not refuel the machine while smoking or when near open flame or sparks. Always stop engine before refueling machine. Fill fuel tank outdoors. Prevent fires by keeping machine clean of accumulated trash, grease, and debris. Always clean up spilled fuel. Use only an approved fuel container for transporting flammable liquids. Never fill fuel container in pickup truck with plastic bed liner. Always place fuel container on ground before refueling. Touch fuel container with fuel dispenser nozzle before removing can lid. Keep fuel dispenser nozzle in contact with fuel container inlet when filling. Do not store fuel container where there is an open flame, spark, or pilot light such as within a water heater or other appliance.
Prevent Battery Explosions
Battery Explosions Keep sparks, lighted matches, and open flame away from the top of battery. Battery gas can explode. Never check battery charge by placing a metal object across the posts. Use a volt-meter or hydrometer. Do not charge a frozen battery; it may explode. Warm battery to 16°C (60°F).
