Checking The Spark Plug - Makita EBH340U Instruction Manual

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.
– Remove the air cleaner cover-fixing bolts.
– Pull the cover lower side and detach the air cleaner
cover.
– 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 element, be sure to dry it completely.
Insufficient drying of the element may lead to difficult
startup.
– Wipe out with waste cloth, oil adhering around the air
cleaner cover and plate breather.
– Immediately after cleaning is finished, attach the cleaner
cover and tighten it with fixing bolts. (In remounting, first
place the upper claw, and then the lower claw.)
Points in Handling Air Cleaner Element
– Clean the element several times a day, if excessive
dust adheres to it.
– If operation continues with the element remaining not
cleared of oil, oil in the air cleaner may fall outside,
resulting in oil contamination.

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
with carton or fouled, clean it thoroubhly 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 grease may be purchased from your MAKITA
dealer.)
