■

• 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). 

■

• 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. 

■

• 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. 

■ 

• When the engine runs short of fuel supply,

check the fuel cap and the fuel filter for
blockage.

■ 

• 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).

• 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.
