5.1.4 How to Lubricate Each Part
・ Be sure to lubricate each part with grease or lubricating oil ( #30 ) for every 30 hours of use. If you neglect
lubrication and allow oil to run out, machine operation will become sluggish and the machine could be
damaged.
5.2 How to inspect, Maintain, and Adjust each engine part
5.2.1 How to clean the air filter
・ To avoid fire and damage to the machine, always keep the air filter and recoil starter free of debris.
・Do not start the engine with the air filter removed. Dirt and dust will be sucked into the engine, causing
engine trouble and abnormal wear and tear.
1. Unscrew the wing nut and remove the air cleaner cover.
2. Remove the paper and foam elements and check for damage. Note:
Replace with new parts if damaged.
3. Wash the foam element with a pH neutral detergent. After washing, be
sure to squeeze out all the water and allow it to dry. After that, soak it in
new engine oil (SAE10W-30 equivalent), wring it out thoroughly, and then
shake to remove any surplus oil.
4. Lightly tap the paper element several times to remove any waste. Blow
any dirt from the inside of the filter in an outward direction.
5. Wipe any dirt from the inside of the case and reassemble back to its
original position.
・ When washing the foam element, remove it gently to avoid tearing.
Recommended cleaning and replacement schedule for the foam element (approx)
Cleaning Every time after operation
Replacement Every 100 hours
・Take care to clean the filter more frequently when operating in an environment with a lot of dust or grime.
