5.3. General Maintenance of Functioning Components
The general maintenance operations that should be carried out regularly are as follows:
1) Keep the rack lift table, overall machine, & path of the drilling free of any offcuts, accumulated swarf &
lubricants by using compressed air or preferably thread-free cloth.
2) Lubricate the drill shaft & rotary chuck regularly with an
NLGI 2 extreme pressure grease, Shell Alvania No.1
grease
or equivalent.
3) Check the belt condition & tension regularly.
Do not over tighten belts,
as this will inadvertently exert
tension on the spindle & motor bearings. To provide the right tension, follow the belt manufacturer’s
recommendations & specifications.
4) Clean & lubricate any moving joints or sliding surfaces with good quality oil.
5) Clean the drill machine regularly & keep any unpainted surfaces lightly oiled to protect from rust & corrosion.
6) Ensure that the machine performs drill perpendicular to the work surface. If not, contact
Brobo Group
engineering department.
