Raider RD-GCS19 Manuel D'instructions page 19

When felling trees observe all safety rules and do as follows: When the chain is pinched, switch off the chain saw and
release the chain with a wedge. Wedge should be made of wood or plastic. Never use steel or cast iron wedge. Falling tree
may pull other trees. Danger zone radius is 2.5 height of the falling tree. If the operator is inexperienced or amateur it is
recommended to have training rather than gaining the experience without supervision. Do not fell trees when: Conditions in
danger zone cannot be determined due to fog, rain, snow or darkness. Line of tree felling cannot be determined due to wind
or wind blows.
4.14. Cutting through trunks.
Press the bumper spike against the material and make a cut.
If the cutting cannot be finished even after the chain saw range is fully utilized, do as follows: Move the guide bar back from
the cut material to a certain distance (with cutting chain still operating) and move the main handle a little down, support the
bumper spike and finish the cut by lifting the main handle a little.
4.15. Cutting a trunk lying on the ground.
Always keep good feet and ground grip. Do not stand on the trunk. Watch out for possibility of the trunk rotation. Observe
manual guidelines related to work safety to avoid the chain saw recoil. Always finish cutting at the side opposite to compressive
stress to avoid pinching the chain in kerf. Before starting to work check the stress direction in the trunk that is to be cut, to avoid
pinching chain of the saw. To eliminate stress, the first cut should be made at the tension side. When cutting a trunk that is
lying on the ground, first make a cut deep 1/3 of the trunk diameter, then turn the trunk over and finish cutting at the opposite
side. When cutting a trunk that is lying on the ground, do not allow to sink the cutting chain into the ground under the trunk.
Negligence may cause immediate damage to the chain. When cutting trunk that is lying on the slope, the operator should
always be at the slope side above the trunk.
4.16. Cutting a trunk lifted above the ground.
In case the log is supported or placed on stable sawing horse, depending on the place of operation, make the cut 1/3 of the
trunk diameter deep on the side under tension and finish cutting on the opposite side.
4.17. Trimming and cutting bushes and tree branches.
Start cutting branches of a felled tree at its base and continue towards top of the tree. Do small branches with a single cut.
First, check which way the branch bends. Then make a cut from the inside of the bend and finish cutting on the opposite side.
Be careful, the branch being cut may spring back. When trimming tree branches, always cut downward to enable free fall of cut
branch. However, sometimes undercutting the branch from the bottom may be helpful. Be very careful when cutting a branch
that may be under stress. Such branch may spring aside and hit the operator. Do not cut branches when climbing up the tree.
Do not stand on ladder, platforms, logs or positions that may cause loss of balance and control over the chain saw. Do not cut
above level of your shoulders. Always hold the chain saw with both hands.
5. Operation and maintenance.
Ensure the engine is switched off and is cold before cleaning, checking or repairing the chain saw. Disconnect wire from the
ignition plug to prevent accidental start up of the engine.
5.1. Storage.
Empty the fuel system before deciding to store the tool for more than one month. Drain fuel from the fuel tank, start the
engine and allow it to use all remaining fuel and stop working. Use new fuel each season. Never use any cleaning agents on
fuel tank, it may damage the engine. Pay special attention to keep the ventilation holes of the engine casing pervious. Clean
plastic parts with mild detergent and a sponge. You can proceed with maintenance actions only described within this instruction
manual. Any other action can be carried out only by authorized service. Do not make any changes in chain saw construction.
