POINTS ON OIL
– Never discard replaced engine oil in garbage, earth or sewage ditch. Disposal of oil is regulated by law. In disposal, always follow the
relevant laws and regulations. For any points remaining unknown, contact Authorized Service Agent.
– Oil will deteriorate even when it is kept unused. Perform inspection and replacement at regular intervals (replace with new oil every 6
months).
CLEANING OF AIR CLEANER
DANGER: INFLAMMABLES STRICTLY PROHIBITED
Interval of Cleaning and Inspection: Daily (every 10 operating hours)
– Turn the choke lever to the full close side, and keep the carburetor off from
dust or dirt.
– Loosen the fixing bolt.
– Remove the air cleaner cover by pulling its bottom side.
– Remove the elements and tap them to remove dirt.
– If the elements are heavily contaminated:
Remove the elements, immerse them in warm water or in water-diluted
neutral detergent, and dry them completely. Do not squeeze or rub them
when washing.
– Before attaching the elements, be sure to dry them completely. Insufficient
drying of the elements may lead to difficult startup.
– Wipe out oil adhering around the air cleaner cover and the breather part with
waste cloth.
– Fit the element (sponge) into the element (felt).
Fit the elements into the plate so that the sponge faces the air cleaner cover.
– Immediately attach the cleaner cover and tighten it with fixing bolts. (In
remounting, first place the upper claw, and then the lower claw.)
NOTICE:
– Clean the elements several times a day, if excessive dust adheres to it.
Dirty elements reduce engine power and make starting engine difficult.
– Remove oil on the elements. If operation continues with the elements
remaining not cleared of oil, oil in the air cleaner may fall outside,
resulting in contamination of the environment.
– Do not put the elements on the ground or dirty place. Otherwise they
pick up dirt or debris and it may damage the engine.
– Never use fuel for cleaning the elements. Fuel may damage them.
CHECKING THE SPARK PLUG
– Only use the supplied universal wrench to remove or to install the spark plug.
– The gap between the two electrodes of the spark plug should be 0.7 - 0.8 mm
(0.028" - 0.032"). If the gap is too wide or too narrow, adjust it. If the spark
plug is clogged or contaminated, clean it thoroughly or replace it.
CAUTION: Never touch the spark plug connector while the engine is running
(danger of high voltage electric shock).
SUPPLY OF GREASE TO GEAR CASE
– Supply grease (Shell Alvania 2 or equivalent) to the gear case through the
grease hole every 30 hours. (Genuine MAKITA/DOLMAR grease may be
purchased from your MAKITA/DOLMAR dealer.)
