MAINTENANCE
To keep your diamond coring machine in
top condition, periodic maintenance must
be performed. In addition always check for
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.

following:
•
Lubricate the rack and pinion of the
rig.
•
Adjust gibs as needed
•

Replace the carbon brushes as
needed

Each year perform a full mechanical
inspection, cleaning and re-lubrication
of all gears, pinions, clutch, etc.
●THE CARBON BRUSHES
Carbon brushes are a consumable part
and must be replaced when a specified
wear limit has been reached. These are full
stop brushes, so if they are worn to their
limit, the motor will not be able to run. Both
brushes should be replaced at the same
time.
Replacement:
1. Remove the main handle/motor tail
cover to gain access to the brushes.
2.
Remove the screw to the brush lead
and move the brush spring to one
side.
3. Slide out the old brush.
4. Slide in new brush and ensure proper
alignment of the spring. Reattach the
brush lead.
5. Repeat for the other brush.
6. Replace the tail cover.
Always entrust all repairs to an authorized
service agent.
● If the replacement of the power supply
cord is necessary, this has to be done by
the manufacturer or their agent in order to
avoid a safety hazard.
