5. Maintenance.
Water pump (Fig. 3-1)
All water in the pump should be drained from the housing, by means of the
drain plug. Water left in the pump housing may cause damage by corrosion;
there is also the danger of *freeze-up" damage in cold weather.
NOTE!
When the pump is used for the pumping of seawater, chemical fluid, or water
which may contain any type of contaminant, the pump should always be "run
through" with clean water prior to storage.
Air filter (Fig. 3-2)
The air filter must be cleaned from dust and dirt in order to avoid:
• Carburetor malfunctions.
• Starting problems.
• Engine power reduction.
• Unnecessary wear on the engine parts.
• Abnormal fuel consumption.
Clean the air filter daily or more often if working in exceptionally dusty areas.
Cleaning the air filter
Remove the air filter cover and the filter. Rinse it in warm soap suds. Check that
the filter is dry before reassembly. An air filter that has been used for some time
cannot be cleaned completely. Therefore, it must regularly be replaced by a new
one. A damaged filter must always be replaced.
NOTE! (TCP - 25)
Saturate the element in 2-cycle oil or the equivalent. Squeeze the element to
distribute the oil completely and to remove any excess oil.
Spark plug (Fig. 3-3)
The spark plug condition is influenced by:
• An incorrect carburetor setting.
• Wrong fuel mixture (too much oil in the gasoline)
• A dirty air filter.
• Hard running conditions (such as cold weather).
These factors cause deposits on the spark plug electrodes, which may result in
malfunction and starting difficulties. If the engine is low on power, difficult to
start or runs poorly at idling speed, always check the spark plug first. If the spark
plug is dirty, clean it and check the electrode gap. Readjust if necessary. The
correct gap is 0.6 mm. The spark plug should be replaced after about 100
operation hours or earlier if the electrodes are badly eroded.
NOTE!
In some areas, local law requires using a resistor spark plug to suppress ignition
signals. If this machine was originally equipped with resistor spark plug, use same
type of spark plug for replacement.
Muffler (Fig. 3-4)
Remove the muffler and clean out any excess carbon from the exhaust port or
muffler inlet from time to time in order to avoid power-loss.
