Idle Speed Adjustment (Fig. 9)
When the idle speed is adjusted properly, the engine will run smoothly, without pressing
the THROTTLE LEVER.
If adjustment is required:
1. Start the engine.
2. Using a long, Philips head screwdriver
gently close (clockwise) the T-screw until
the Powerboard starts to move forward.
3. Then open (counter-clockwise) the screw
until the Powerboard stops.
4. You have reached the correct idle speed
when the engine runs smoothly below the
RPM when the Powerboard starts to move.
Note: Standard idle RPM is about 2500-
3000 RPM.
WARNING!
When the engine is idling, under no circumstances should your
powerboard be moving. If the unit continues to move after idle speed
adjustment, contact your local Tanaka Dealer.
Cleaning the Air Filter
It is a good idea to occasionally clean the air filter to insure optimum performance.
To clean the air filter:
1. Using a Philips head screwdriver, remove
the carburetor cover by turning the cover
screw counter clockwise. (Fig. 10)
2. Rinse it in warm soap suds.
3. Check that the filter is dry before
reassembly.
4. Put the air filter back into its original
position (fig. 11) and replace the cover.
NOTE: An air filter that has been used for
some time cannot be cleaned completely.
Therefore, it must regularly be replaced with a
new one. A damaged filter must always be
replaced.
