3. REPLACING THE IMPORTANT PARTS
Lubrication
Any machine is generally in its best condition when delivered; therefore, it is necessary
to try to keep this condition. Unexpected failure occurs due to lack of oil, debris, or
dust. To keep its best condition, periodically clean the machine and apply proper
kinds of oil to each part in which lubrication is needed. Although the frequency of
lubrication varies according to how much the machine is used, at least it is necessary
to lubricate before the machine becomes dry. It is also necessary to wipe off
excessive oil as it collects dirt.
WARNING!
1. Turn off the power switch and disconnect the DC plug of the AC Adapter and the cables
before replacing any parts.
2. Follow all manual instructions. Failure to do so could create safety hazards such as fire
or electrocution.
NOTES:
1. Manual instructions must be followed when installing option kits or adding cables to
avoid system failures and to insure proper performance and operation.
2. Failure to follow manual instructions or any unauthorized modifications, substitution or
change to this product will void the limited product warranty.
CAUTION!
1. To protect the connector pins or component from static discharge, do not touch them
