If that still does not work the only choice is to use a dressing stone.
VIBRATION TROUBLESHOOTING
If vibration occurs and it is not caused by embedded steel, stop drilling to find the cause and remedy.
CAUTION: Do not operate with vibration or there will be serious hazard and the diamond core bit
will surely be destroyed.
Vibration is usually caused by:
1.
A bit with too much runout
SOLUTION: Replace bit.
2. A bit with diamond segments broken off
SOLUTION: Repair or replace bit.
3.
Shifted base or loose gibs
SOLUTION: Retighten mountings or adjust gibs as needed.
KEEP TOOL CLEAN
Wipe down the machine at the end of each work day with a damp cloth.
NEVER use solvents to clean plastic parts. They could possibly dissolve or otherwise damage the material.
Periodically blow low-pressure compressed air through the ventilation slots with the motor running to keep
the motor clean so that motor can be cooled normally.
Wear safety glasses while using compressed air.

MAINTENANCE

Every 50 hours of operation blow compressed air through the motor while running at no load to clean out
accumulated dust. (If operating in especially dusty conditions, perform this operation more often.)
To keep your diamond coring machine in top condition, periodic maintenance must be performed. In
addition always check for a damaged power supply cable, check for loose fasteners and always keep alert
for unusual noises and vibration when operating.
WARNING: Never operate a damaged machine. Always tag a damaged machine and take it out of
service until repairs can be made.
CAUTION: This machine is equipped with an oil bath gearbox. To avoid leakage of lubricating oil,
whenever the gearbox is opened, the o-ring seal must be replaced with a new one.
CAUTION: This machine is equipped with an oil bath gearbox. If the gear oil is found to be leaking out,
have the machine repaired by a qualified service center immediately. Running without sufficient oil will
lead to certain damage of the gearbox.
Maintenance which should be performed by an authorized service center, include the following:
• Replace water seals as needed.
• Replace the carbon brushes as needed
