  ADJUSTING THE VALVE CLEARANCE EB303001 ENGINE ADJUSTING THE VALVE CLEARANCE The following procedure applies to all of the valves. NOTE: S Valve clearance adjustment should be made on a cold engine, at room tempera- ture. S When the valve clearance is to be mea- sured or adjusted, the piston must be at top dead center (TDC) on the compression stroke.

• Page 63
  ADJUSTING THE VALVE CLEARANCE a. Turn the crankshaft counterclockwise. b. When piston #1 is at TDC on the com- pression stroke, align the TDC mark a on the generator rotor with the mark b on the crankcase. NOTE: TDC on the compression stroke can be found when the camshaft lobes are turned away from each other.

  CHECKING AND CHARGING THE BATTERY EB305020 ELECTRICAL SYSTEM CHECKING AND CHARGING THE BATTERY Batteries generate explosive hydrogen gas and contain electrolyte which is made of poisonous and highly caustic sulfuric acid. Therefore, always follow these preven- tive measures: S Wear protective eye gear when han- dling or working near batteries.

• Page 101
  CHECKING AND CHARGING THE BATTERY NOTE: Since MF batteries are sealed, it is not pos- sible to check the charge state of the battery by measuring the specific gravity of the elec- trolyte. Therefore, the charge of the battery has to be checked by measuring the voltage at the battery terminals.
• Page 102
  CHECKING AND CHARGING THE BATTERY Do not quick charge a battery. S Make sure that the battery vent is free of obstructions. S Never remove the MF battery sealing caps. S Do not use a high-rate battery charger. They force a high-amperage current into the battery quickly and can cause battery overheating and battery plate damage.
• Page 103
  CHECKING AND CHARGING THE BATTERY Charging method using a variable-current (voltage) type charger Measure the open-circuit NOTE: voltage prior to charging.
