Solo 635 ECO Instruction Manual page 29

The best cutting performance is attained with the recommended
depth gauge and distance (depth gauge setting).
1. Check the depth gauge setting during each sharpening.
2. Place depth gauge tool on the cutter. If the depth gauge
projects, file it level with the top of the tool using a flat file.
3. Round off the front corner to maintain original shape of depth
gauge.
CAUTION! Too large a depth
gauge setting increases the
danger of kick-back.
Guide Bar Maintenance
The guide bar requires maintenance just like the saw chain. The
bar rails must be square and flat and the bar groove must not be
widened.
To prevent such one-sided wear of the bar, it is recommended
that you turn the bar over after each sharpening.
Grease the bearing of the sprocket on sprocket nose type bars
with bearing grease and the special grease gun by pressing it
into the lube port hole while rotating the sprocket (fig.43). (See
maintenance chart)
IMPORTANT!
The guide bar is specifically designed to be a guide track for the
saw chain. Therefore, it should never be used as a pry bar or
crow bar. Any twisting, prying, or lifting inside the cut, shortens
the life span of the bar. No warranty is extended for such
application! (fig.42)
CHAIN SAW CLEANING
After each cutting task, clean chain saw thoroughly and check it
over for any damage. Especially important check points are: chain
brake, cooling air intake vent areas, cylinder fins and air filter.
CAUTION! To prevent eye injury, wear safety goggles
whenever using compressed air.
For cleaning, use only environmentally safe cleaning material
offered by dealers.
Never clean chain saw with gasoline (petrol)!
CHAIN BRAKE MAINTENANCE
Operator Check:
Check smooth functioning periodically. Remove resin, chips and
foreign matter. Apply grease or high temperature motor oil to
visible joints (fig.44).
Brake test:
- Start engine.
- Engage brake („on") while idling.
- Apply full throttle briefly.
- The chain must remain stopped.
Air Filter cleaning:
Clogged air and pre-filters result in performance loss and
increased fuel consumption thereby leading to elevated levels
of toxins and damaging components in the exhaust fumes.
Starting up is also more difficult.
Clean both air filters (if applicable, pre-filter and fine filter daily
after day-long cutting). Clean more often during increased dust
accumulation.
In most cases, simply tapping is best suited for the filter.
If filters are heavily soiled, they can be cleaned with non-
flammable cleaning solvents (warm soapy water). Both filters
must be completely dry prior to re-installation.
If filter elements are damaged, replace affected part.
No warranty is extended if engine failure is caused by improper
care.
For removal and installation, remove engine cover or
filter cover, close choke to prevent dirt particles from
entering the carburetor. Then remove air filter.
With two part filter, remove retainer clips and separate filter
halves (fig.45).
During installation, insure precise positioning, correctly closed
filter halves and proper alignment and fit on the carburetor.
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".
