Maintenance
• Make sure that the engine has stopped
and is cool before performing any
service to the hedge-trimmer. Contact
with moving cutting head or hot muffler
may result in a personal injury.
■
DAILY INSPECTION
• Check all the fasteners for loose or missing
ones.
• Brush off dirt on the blades and apply a
light coating of oil.
• The blades are loose-installed to the guide
bar with several screws and nuts. Do not
tighten up those screws, or the blades will
be locked and result in clutch failures.
Allow the screws a half spare turn, and
secure there with the nut(See NOTE on
page 8).
■
GEAR CASE
• At every 25 hours of use, supply grease to
the gear case. Pump in grease via the
grease fitting until it comes out of the root
of blades.
■
AIR FILTER
• The air filter, if clogged, will reduce the
engine performance. Monthly check and
clean the filter element in warm, soapy
water as required. Dry completely before
installing. If the element is broken or
shrunk, replace with a new one.
NOTE
WARNING
■
FUEL FILTER
• When the engine runs short of fuel supply,
check the fuel cap and the fuel filter for
blockage.
■
SPARK PLUG
• Starting failure and mis-firing are often
caused by a fouled spark plug. Periodically
clean the spark plug and check that the
spark gap is in the correct range. For a
replacement plug, use the correct type
specified by RedMax(See SPECIFI-
CATIONS on the page 15).
• REPLACEMENT PLUG IS A CHAMPION
RCJ6Y OR THE EQUIVALENT, SUCH AS
BOSCH WR8E OR NGK BR6S.
• Note that using any spark plugs other than
those designated may result in the engine
failing to operate properly or in the engine
becoming overheated and damaged.
• To install the spark plug, first turn the plug
until it is finger tight, then tighten it a
quarter turn more with a socket wrench.
