Every 50 service hours

6.1.1 Drain water and sediment from the
fuel tank and water separator
Remove the drain plug and allow any water and
sediment to drain. Drain at least 1 or 2 liters (0.3 to
0.5 U.S. gal) of fuel to remove the water and
sediment.
It is evident that invisible particles of dirt in
sediment which might pass through the filter will
damage the finely finished parts of the fuel
injection system.
DANGER
Do not smoke while draining out the water and
sediment. Keep flames and sparking devices
away from this area. Clean up any spillage
before starting the engine.
6.1.2 Check the battery electrolyte level
and specific gravity
1. Maintain the electrolyte level between UPPER
and LOWER marks on the case. If the battery
has not got any level marks, maintain the level
10 to 15 mm (0.4 to 0.6 in.) above the cells.
Remove the filler caps and add distilled water
when necessary.
2. Test the specific gravity of the battery
electrolyte with a battery hydrometer. The

WARNING
• Battery gives off flammable fumes that are
explosive.

electrolyte level.
• Electrolyte is an acid and can cause
personal injury if it comes into contact with
the skin or eyes.
• Always wear goggles when working with the
