Air Filter Cleaning (fig. 50 + 45)
Clogged air & pre-filters cause performance loss and increased
fuel consumption. This leads to a higher toxin level in the exhaust
gas and also makes starting more difficult.
After cutting all day, clean both pre-filter and main filter daily.
In severe dust conditions clean more often. Simply tapping the
filter against an object is the best method of cleaning. If the
filters are heavily soiled, wash them in non-flammable cleaning
solvents (warm soapy water). Both filters should be completely
dry before re-installing. Replace damaged filters. Warranty claims
cannot be accepted for damaged engine parts caused by
improper care and maintenance. For removal and installation,
remove cover (fig.50), close choke to prevent dirt entering the
carburetor and remove filter. Ensure the filter is re-fitted properly
in its correct position. Periodically remove dirt and dust from the
air intake area (fig. 50A). If required, this should be done daily.
CARBURETTOR ADJUSTEMENT
The carburettor is adjusted at the factory for optimum performance.
Subject to location (mountains, plains), the carburettor may need to
be adjusted.
The carburettor is equipped with 3 setting screws:
• Idle end stop, screw „T" (Pos.16)
• Idle mixture, screw „L" (Pos.17)
• Full load mixture, screw „H" (Pos.17)
The regulating screws for idle mixture (L) and full
load mixture (H) must only be adjusted by
qualified mechanics.
Minor adjustments of the idle setting to the average idle
speed stated in the specification can be made via the idle end
stop screw (T) using a tachometer as follows:
- Turn the idle end stop screw (T) a little anticlockwise, if the
idle speed is too high.
- Turn the idle end-stop screw (T) a little clockwise, until the
motor runs smoothly, if the idle speed is too low (in other
words if the engine refuses to start or stalls).
Under no circumstances must the chaine driven at
idle speed.
Ask an authorised service shop to adjust your machine, if you
cannot obtain an optimum carburettor adjustment by
correcting the idle end stop screw „T".
The following instructions are for authorised service shops:
Using the D-CUT carburettor:
key (SOLO part no: 00 80 537) to correct settings on the idle
mixture screw (L) and on the full load screw (H).
Using the carburettor with limitercaps:
The regulating screws for idle mix and full charge mix can only
be adjusted in a limited range.
The air filter must be clean to achieve the correct idle
adjustment. Let the engine run until it is warm, before making
any adjustments. Maintain the values regarding the average
idle speed and maximum permissible speed stated under
"Specification".
Please note: The carburettor is adjusted to
achieve maximum engine power. Always use a
tachometer to carry out this adjustment.
ANTI-VIBRATION SYSTEM (fig. 47)
Should the vibration level suddenly increase, especially when
compared with the level when the saw was new, immediately
check all anti-vibration mounts for damage and replace if
required.
Caution! Operating a chain saw with damaged anti-
vibration system will endanger your health!
CHAIN SPROCKET AND CLUTCH (fig. 48)
Always inspect the condition of the chain sprocket before fitting
a new replacement chain. Worn sprockets will damage a new
saw chain. The sprocket bearing in particular is subject to high
stress and should be lubricated regularly with a high quality
bearing grease, such as Mobiltemp 78 for example. (See also
maintenance chart).
REPLACEMENT OF SPROCKET AND CLUTCH ASSEMBLY
The following notes are intended for use by Service Centers!
The clutch assembly is threaded to the crankshaft.
Caution, left hand thread! Turn clockwise to remove clutch.
Ensure proper installation sequence is followed. Some special
tools are required to replace clutch drum and chain sprocket.
MUFFLER MAINTENANCE
A damaged muffler is a fire hazard and can also lead to hearing
problems. Regularly check muffler condition and muffler
retaining bolts.
CAUTION!
Never touch hot exhaust!
SPARK PLUG REPLACEMENT
CAUTION!Do not touch spark plug or spark plug cap
while engine is running. (high voltage)
Service work should only be performed with switched off engine.
Avoid burns while engine is hot. Wear protective gloves!
Ignition problems which are not solved with a change of spark
plug and/or plug cap should be referred to an authorized service
center or specialized dealer.
Notes on Spark Plug: (fig. 49)
Thermal range = 200
Electrode gap = 0.5 mm (.020")
Checking of the ignition system should start with the spark plug.
Checking for ignition spark
- Use an insulated pair of pliers, hold spark plug in plug cap
against the cylinder but not near plug opening.
– Move ignition stop switch to 'I'.
- Pull starter rope firmly.
If the ignition system is in good condition, a visible spark should
arc across the electrodes of the plug.
