How to clean the air filter
If you continue to use the machine with the air filter and recoil starter clogged with weeds, etc,
exhaust gas temperature will increase and could ignite fuel, resulting in a fire. Be sure to periodically
clean these parts.
When washing the foam element, remove gently to avoid tearing.
Cleaning and replacement times of the foam element (approx)
Cleaning
Every 25 hours
Replacement
Every 200 hours or 1 year
・
Take
care to clean the filter more frequently when operating in an environment with a lot of dust or
grime.
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.
Release the wing nut and air cleaner cover.
2.
Remove the paper and foam elements and check whether they
are damaged.
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 hard, 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.
Before starting operation, check there are no weeds or
leaves blocking the inside the dust cover or recoil starter .
As for the cooling fan, remove accumu lations of weeds or
leaves from inside of the fan cover by blowing
compressed air through it after every 100 hours or 1 year
of usage
If you continue to operate the machine with the engine
blocked, the engine will lose the ability to stay cool,
causing engine trouble and possible burns if touched.
The bolts securing the dust cover and recoil starter are
firmly fixed. Please remove the bolts in order to clean
inside the dust cover and recoil starter.
However,
cleaning of the inside of the fan cover should be
performed by the
authorized OREC dealer.
Please
request this from the retailer where you purchased the
machine. (Please note, there is a charge for this
service.
