REPLACEMENTS AND ADJUSTMENTS
Adjusting for depth of cut
To ensure safety, UNPLUG machine from its power
source before adjusting for depth of cut. It's imperative
that the key guide and the cutter be in the same plane,
that is, aligned to each other. If the cutter guide protrudes
further than the cutter, the resulting cuts in a key blank
will be too shallow and the duplicate key will not work.
Likewise, if the cutter guide is behind the cutter, the cuts
in the key will be too deep (see Fig. 6).
Figure 6
To check the depth adjustment, insert two identical key
blanks into the vise jaws, setting them flat in each vise. It
is not necessary to align the blanks. Then, raise the
carriage, positioning the left blank against the cutter
guide and the right blank against the cutter. Next, turn
the machine pulley by hand and note the right key blank.
The cutter should just barely graze the key blank when
the adjustment is correct.
No cutter is perfectly round so make one complete
rotation of the cutter before changing adjustment. There
will be a high point on the cutter; the adjustment should
be made to the high point. If the cutter does not touch the
key blank after one rotation, proceed to change the
adjustment.
To adjust cutter guide, loosen set screw on top of the
guide. With a flat screwdriver, turn adjusting screw in (to
increase depth of cut) and/or out (to decrease depth of
cut). Again, proper adjustment is achieved when the
cutter barely grazes the key blank.

Maintenance
1. The carriage spindle should be lubricated periodically
by wiping lightly with an oily rag. The cutter shaft is
lubricated by the oil impregnated bronze bearings.
After extended use, these bearings should be
lubricated with a light machine oil applied to their
end to assure continued smooth operation.
2. Keep the model 008A clean. The cutter should be kept
free of filings and dirt. A wire brush may be used for
this purpose, being careful not to chip or dull the
cutter. The motor should also be free of filings.
Compressed air is recommended for cleaning the
motor.
3. The machine should be picked up by the base, not the
carriage ... as tempting as it seems. Alignment of the
carriage is critical for accurate duplication of keys and
this type of handling is not suggested.

Replacing the drive belt

1. Remove screw which holds hood in place and remove
hood.
2. Using allen wrench supplied with machine, loosen
both set screws located in cutter shaft pulley.
3. Slide cutter shaft to the left and remove cutter shaft
pulley and belt.
4. Place new belt and pulley in position and slide the
cutter shaft back to the right. Before tightening (2) set
screws in cutter shaft pulley, make sure cutter and
pulley are snug against bronze bearings in left
supporting post. This insures minimum end play.
Cleaning
Your machine should be kept clean of all filings and dust.
The most critical areas are the carriage jaws and shafts. A
one inch paint brush is ideal to brush these areas of the
machine. The shafts should be wiped periodically with a
lightly oiled cloth. We suggest brushing the jaws often as
even a single filing can alter the accuracy of the machine.
