1.7 PREPARATION Before starting any removal of parts, proper preparation is very important for efficient work. A clean work area at the start of each job will allow you to perform service repairs easily and quickly. in the disassembly order on a clean work surface. Organization is a key part of proper reassembly. Tools, instruments, and parts needed for the job should be gathered before work is started. Interrupting a job to locate tools or parts is a needless delay.
Disengage mower clutch, stop engine, remove key and wait for moving parts to stop before leaving operators position for any reason such as removing grass catcher or unclogging chute. Mow only in daylight or good artificial light. Do not operate the machine while under the influence of medication, alcohol or drugs. Do Not Do not turn on slopes unless necessary, and then, turn slowly and gradually, downhill, if possible. Do not mow near drop-offs, ditches, or embankments.
Keep machine free of grass, leaves, or other debris build-up. Clean up oil or fuel spillage. Allow machine to cool before storing. Stop and inspect the equipment if you strike an object. Repair any damage before restarting. Never make adjustments or repairs with the engine running or when engine and exhaust parts are hot from operation. Grass catcher components are subject to wear, damage, and deterioration, which could expose moving parts or allow objects to be thrown.

These pumps are connected in the fuel line between the fuel supply and the carburetor or directly to the fuel inlet. Figure 47 Impulse fuel pumps are operated by crankcase impulses created by the up and down movement of the piston.
SECTION 11 - ELECTRICAL 11.1 TOOLS 11.2 ELECTRICAL MEASUREMENTS There are some specialized tools and test equipment that are needed for electrical repair work. A brief description of these follows. In many electrical circuits, there is some visible effect which indicates that the circuit is functioning properly. A switch is turned "ON" and a lamp lights. A key is turned, a starter motor runs and cranks the engine.
Voltage Measurement Maintenance: A voltmeter measures the voltage difference between the test leads and the voltmeter is always connected across the circuit under test. Do an occasional visual inspection. See to it that the battery remains clean, both the case and the terminals. This visual inspection should be done once a month. Current Measurement Check the level of the electrolyte. It may be necessary to add distilled water. This should be checked before each usage.
Storage: 11.4 SWITCHES During the off season it is important to have the battery in the same good condition or it will not deliver power when needed. Switches either open a circuit to stop current flow or close and allow current to flow through. 1. Make sure the battery is fully charged and the electrolyte is to the proper level. 2. Make sure the battery is clean (both the case and terminals.) 3.
the meter should move to open circuit (high resistance). Check from each terminal to ground (switch case). Meter should show open circuit (high resistance). Relay (03042800) Ignition Switch 87 NOTE: Refer to the wiring diagram of the unit involved to determine switch functions and test using the methods described.
If all the lights are out, check the fuse for continuity (high resistance indicates a defective or blown fuse). If the fuse is blown, check for a short in the wiring and correct before replacing the fuse. If the fuse and lamps are good, check the circuit with an AC/DC voltmeter. 11.7 FUSES Fuses are connected in electrical circuits to protect the circuits from damage due to overload or short circuits. Fuses are a "weak link" in the circuit.
11.8 DIODES AND RECTIFIERS Diodes are solid state, semiconductor devices. They contain no moving parts and conduct current better in one direction than the other. They are electrical "check valves" and permit current flow in one direction, but not in the other. Diodes allow current to flow through one circuit without "backing up" into another. In engine alternator circuits a diode is used to convert current which flows back and forth (AC) in a circuit to current which flows only in one direction (DC).
Step 2: Use a voltmeter to make sure you have power to terminal (B) on the back side of the ignition switch in the off position. If you don’t have power to terminal (B) check the battery connections and the fuse in the red lead. Step 3: With the ignition switch in the "run" position, check to see if power has been transferred from terminal (B) to terminal (A).
11.11 SWITCH CONTINUITY The diagrams below show the various states of connection for electrical components. The solid lines on switches show continuity. NOTE: All switches are viewed from the rear.
