When not in use, chain saw should be stored clean, on flat surface, in dry place and beyond reach of children. When storing it is
important to avoid deposition of rubber particles in basic parts of the fuel system, such as carburettor, fuel filter, fuel line and fuel
tank. Fuels with alcohol additives (ethanol or methanol) may absorb moisture and that during storing causes separation of fuel
blend ingredients and formation of acids. Acidic petrol may damage the engine.
5.2. Air filter.
Dirty air filter reduces efficiency of combustion engine and causes increase of fuel consumption. Clean the air filter after each
5 hours of the saw operation. Clean the air filter lid (4) and its surroundings, so the dirt does not get into carburettor chamber
after the lid is removed. Unscrew knob for air filter lid (3) and remove air filter lid (4). Remove air filter. Use water with soap
to clean the filter, wash with clean water and dry thoroughly. Install air filter. Ensure the grooves on the air filter rim match
protrusions on the air filter lid (4). When installing the air filter lid (4) make sure to properly place ignition plug wire and access
sleeves for carburettor adjustment screws. Do not wash the air filter in petrol or any other flammable solvent to avoid fire hazard
or appearance of dangerous vapours.
5.3. Cylinder fining.
Dust deposition on the cylinder fining may cause motor overheating. Check regularly and clean the cylinder fining when
carrying out maintenance of the air filter.
5.4. Guide bar and saw chain.
Check condition of the guide bar and chain every 5 hours of the saw operation. Set the ignition switch (11) to off position.
Loosen and unscrew the guide bar fixing nuts. Remove the casing and disassemble guide bar (14) and chain (15). Clean oil
holes and groove in the guide bar (14). Lubricate tip chain wheel of the guide bar (16) through the hole located on the guide bar
tip. Check condition of the chain (15).
5.5. Chain sharpening.
Pay attention to cutting tools. Cutting tools should be sharp and clean, it allows efficient and safe operation. Operating the
saw with blunt chain causes quick wear of the chain, guide bar and driving chain wheel, and breaking the chain in the worst
case. That is why it is important to sharpen the chain on time. Chain sharpening is a complex operation. Sharpening the chain by
yourself requires use of special tools and skills. It is recommended to entrust sharpening the chain to qualified persons.
5.6. Fuel filter.
Unscrew the fuel filler plug (12). Use wire hook to remove the fuel filter through the fuel filler hole. Disassemble the fuel filter
and wash it in petrol or replace with a new one. Install the fuel filter in the tank. Tighten the fuel filler plug (12). When the filter
has been dismantled use the wire hook to hold up the end of the suction line. Be careful during fuel filter installation to prevent
contamination from getting into the suction line.
5.7. Oil filter.
Unscrew oil filler plug (13). Use wire hook to remove the oil filter through the oil filler hole. Wash the oil filter in petrol or
replace with a new one. Remove dirt from the tank. Install the oil filter in the tank. Tighten oil filler plug (13). When putting the oil
filter into the tank make sure it reaches front right corner.
5.8. Ignition plug.
To maintain reliable operation of the device, check condition of the ignition plug on a regular basis. Remove air filter lid (4).
Remove air filter. Remove wire from the ignition plug. Put on plug key (included) and unscrew the ignition plug. Clean and adjust
spacing between contacts (0.65 mm) (replace ignition plug when necessary).
5.9. Other instructions.
Ensure there are no fuel leaks, loosened joints or damages of main parts, especially main handle joints and guide bar fixing.
When you find any damage, make sure it is repaired before next use of the chain saw. All faults should be repaired by service
workshop authorized by the RAIDER.
Read the instructions' manual before using the
machine.
On all jobs performed with the saw you
must always wear safety goggles to
guard your eyes from flying materials/
objects and a sound-proof helmet,
earmuffs or the like to protect your hearing. Wear a safety
helmet if there is a risk of objects falling on you from above.
Warning! Danger!
Protect yourself from saw kickback.
Hold the chainsaw securely with both hands during
use.
