3 Signs And Symbols - Oregon 720-120 Original Instruction Manual

WARNING Before a chain is sharpened, make sure that the grinding wheel is not cracked and does
not vibrate or wobble. If the grinding wheel is damaged, it must be replaced immediately, see section
6.3, "Change the grinding wheel and fit the grinding wheel guard." You can also do a simple "ring test" to
check for damage; see 4.7, "Installing the grinding wheel." If abnormal vibrations occur during operation,
immediately stop the machine and check the condition of the grinding wheel.
WARNING Place the power converter where there is as little dust as possible and out of reach of
sparks from the machine.
WARNING Attach air hoses and cables with cable clamps to make sure no one trips over them.
CAUTION Only use accessories that are supplied or approved by the manufacturer.
CAUTION If the pitch is not correctly set, the chain will be pushed into an incorrect sharpening position.
This may result in a damaged chain.
CAUTION If the metal of a cutter turns blue during grinding, the speed is set too high and the metal
is overheated. This can cause the metal in the cutting tooth to lose its sharpness. Replace the damaged
cutter or sharpen the chain again.
CAUTION Grinding dust can interfere with the machine's operation. Clean the machine daily to remove
all of the grinding dust. Use a vacuum cleaner, brush, or similar to clean the machine.
CAUTION Make sure that the floor where the machine is placed is flat and level. Attach the stand to
the floor with screws.
