Checking and adjusting the idling speed
The cutting blades should not run when the engine is at idle.
- Idle speed should be set to 3,000 min
- If necessary, adjust the idle screw (the cutting blades must not run when the
engine is on idle).
• The cutting blades run while idling - turn the idle screw counterclockwise to
decrease the idle speed.
• The engine stops while idling - turn the idle screw clockwise to increase the idle
speed.
If the cutting blades still continue to run at idle after the adjustment, consult your
nearest authorized service agent.
• The clutch should engage at 3,750 min
• Check the functioning of the I-O switch, the lock-off lever and the throttle lever.
Cleaning the air cleaner
DANGER: Inflammables strictly prohibited
Check and clean the air cleaner daily or every 10 operating hours.
- Turn the choke lever to the close side fully, and keep the carburetor free from
dust or dirt.
- Loosen the fixing bolt.
- Pull the rear side of the air cleaner cover and move it forward to detach.
- If oil adheres to the element (sponge), squeeze it firmly.
- For heavy contamination:
1) Remove the element (sponge), immerse it in warm water or in water-diluted
neutral detergent, and dry it completely.
2) Clean the element (felt) with gasoline, and dry it completely.
- Before attaching the elements, be sure to dry it completely. Insufficient drying of
the elements may lead to difficult startup.
- Wipe out oil adhering around the air cleaner with waste cloth.
- Immediately after cleaning is finished, attach the cleaner cover and tighten it with
fixing bolts. (In remounting, first place the upper claw.)
Points in handling the air cleaner elements
- Clean the elements several times a day, if excessive dust adheres to it.
- If operation continues with the elements remaining not cleared of oil, oil in
the air cleaner may fall outside, resulting in oil contamination.
