Drill Maintenance
In order to minimize wear on moving parts and insure
smoother operation and longer life, the following
maintenance should be done periodically, based on use.
1. At intervals of 500 holes or 10 hours of actual running
time, check all fasteners for tightness and retighten if
necessary. This is especially important for fasteners
required for smooth, effi cient cutting action. These
include: Gib screws and nuts, motor hold down
screws, skid plate screws, bracket mounting screws
and nuts, housing bolts, clamp screw and front
support bracket bolts.
2. Coolant bottle must be attached to inducer under
pressure with shut-off valve open to lubricate inducer
o-rings whenever motor, is running.
3. Apply grease to slide dovetails, brass gibs, and the
feed gear rack. (For best results, use Shell Cyprina-RA
or equivalent.)
4. Remove front support bracket from arbor and pack
bearing with grease. (Shell Cyprina-RA or equivalent)
