Cleaning the tube joint
WARNING:
Do not remove the hose band, tube, or cap, when the solution discharge lever is
●
open.
Do not loosen the cap when the solution discharge lever is open.
●
1. Loosen and remove the cap (1) that comes out with the strainer (2).
2. Clear dust and particles away from strainer.
3. Put the strainer back to the original position. Be sure to tighten the cap firmly.

INSPECTION AND MAINTENANCE

DANGER:
Before inspection and maintenance, stop the engine and allow it to cool. Remove also the spark plug and plug cap.
●
If inspection or maintenance is attempted immediately after engine stop or with the plug cap left attached, the operator may suffer burn or an
–
accident due to careless startup.
After inspection and maintenance, make sure that all parts are assembled. Then, proceed to operation.
●
Always wear rubber/chemical-resistant gloves for inspection and maintenance.
●
NOTICE:
Never use gasoline, benzine, thinner, alcohol or the like. Discoloration, deformation or cracks may result.
●
Replacement of engine oil
Deteriorated engine oil will shorten the life of the sliding and rotating parts to a great extent. Be sure to check the period and quantity of replacement.
DANGER:
In general, the engine main unit and engine oil still remain hot just after the engine is stopped. In replacement of oil, make sure that the engine
●
main unit and engine oil are sufficiently cooled down. Otherwise, there may remain a risk of burn. In addition just after of the engine stops all
the oil may not return to crank case. Do not check the oil level right after engine stops.
If the oil filled above the limit, it may be contaminated or may catch fire with white smoke.
●
Interval of replacement: Initially, every 20 operating hours, and subsequently every 50 operating hours
Recommended oil: SAE10W-30 oil of API Classification SF Class or higher (4-stroke engine oil for automobile)

Oil change procedure

1. Set the mist blower down on a level surface.
2. Place a waste oil container under the drainage hole (1) to catch the oil as it drains out.
The container should have a capacity of at least 220 mL to be able to catch all of the oil.
3. Loosen the oil drain bolt (2) to let the oil drain out. Be careful not to allow oil to get on the
fuel tank or other parts.
CAUTION:
Be careful not to lose the gasket (aluminum washer) (3). Place the oil drain bolt (2) in a
●
location where it will not accumulate dirt.
4. Remove the oil cap (4). (Removing the oil cap (4) allows the oil to drain easily.)
CAUTION:
Be sure to set the oil cap (4) down in a location where it will not accumulate dirt.
●
5. As the level of the oil being drained decreases, tilt the mist blower over on to the side with the drain so that the oil will completely drain out.
6. After the oil has completely drained out, tighten the oil drain bolt (2) securely. If the bolt is not tightly fastened, this may result in an oil leak.
CAUTION:
Do not forget to put the gasket (aluminum washer) (3) back on when reattaching the drain plug.
●
7. Adding oil during the oil change procedure is performed in the same manner as the separately explained procedure for adding oil whenever the
level is insufficient. Always add oil by filling from the opening under the oil cap.
(Specified oil level: Approximately 220 mL)
8. After filling with oil, tighten the oil cap (4) securely to prevent oil leaks.
