Carburetor - Efco Power SA 9500 Manual De Instrucciones

WARNING! – Always wear protective
gloves during maintenance operations. Do not
carry out maintenance with the engine hot.
Never carry out maintenance operations with
the engine running.
- Non-correct maintenance and removal of
safety devices could cause serious injuries.
- Do not use fuel mix ture for cleaning
operations.
- Do not attempt to carry out operations
or repairs that are not part of the normal
maintenance. See the authorised dealer.
AIR FILTER
The efficiency of the air intake filter on any
engine is of critical importance so it must be
checked and cleaned regularly. To clean the air
filter, refer to Fig.17 and proceed as follows:
· Unscrew the two knobs to remove the cover
in order to gain access to the filter (as shown
in Fig.17).
· Remove the filter and clean it by knocking it
against a hard surface; then use compressed
air and blow from the side of the metal mesh
and between the pleats, proceeding in a
lengthwise direction.
· Refit the filter and close the cover, tightening
the two knobs.
CAUTION – Using the blower without the
air filter or with a very dirty air filter can damage
the engine and will invalidate the warranty.
Change the filter when it can no longer be
cleaned efficiently.
FUEL FILTER (Fig. 18)
We recommend changing the fuel filter in the
fuel tank at least once a year. This operation
must be carried out by an Authorized Service
Centre:
· Empty the fuel tank.
· Extract the filter and disconnect it from the
fuel hose.
· Fit a new filter in the fuel hose.
· Re-insert the filter in the fuel tank.
CAUTION – Failure to replace the fuel filter
when it is dirty will result in impaired operation
of the engine.
ENGINE
Clean cylinder fins with a brush or compressed
air periodically. Dangerous overheating of engine
may occur due to impurities on the cylinder.
SPARK PLUG
Clean spark plug and check electrode distance
periodically (Fig. 16). Use Champion RCJ6Y or of
other brand with the same thermal grade.
FAN CASING
Following prolonged use of the blower a large
amount of dust may be deposited on the fan casing
(behind the cushion). This obstructs the air flow
(reduced volume) and can result in damage to
the fan and/or overheating of the engine. For this
reason, be sure to clean the fan casing regularly.
Clean the slots in the fan casing: they play an
important role in relation to engine cooling.

CARBURETOR

The carburettor is factory adjusted to standard
settings that comply with emissions regulations.
WARNING:
- Do not change the carburettor settings
by tightening or loosening the regulator
screws; this operation must be performed
by qualified personnel at an Authorized
Service Centre.
- Incorrect adjustment of the carburettor
can cause serious damage to the engine.
- Furthermore, do not tamper with or
remove the red protective caps on the
carburettor regulator screws.
In the case of problems (engine dies when
idling, irregular engine speed or failure to reach
maximum power) seek the assistance of an
Authorized Service Centre.
WARNING: Weather conditions and
altitude may affect carburation.
