LATHE PREPARATION
This is the premium Pro-
Cut tip
(50-742) . When
the tip is mounted cor-
rectly, the chip breaker
and dots face up.
The adapters are made of
case iron, not aluminum or
steel like wheels. They are
not designed to withstand
the use of impact tools.
DO NOT USE IMPACT
GUNS TO ATTACH THESE
ADAPTERS! Twenty to
thirty ft.-lbs. applied by
hand is plenty to secure
the adapter to the vehicle.
Excess torque applied
with an impact wrench
will damage the adapters.
Warranty does not cover
this misuse.
WARNING
Before mounting the lathe, check the cutting tips and make sure they are ready for use. The cutting tips are one of the most
critical components of the machine. It is vital that they are Pro-Cut brand tips in good condition and properly mounted. Each
cutting tip has three corners which may be used. The correctly installed tip is wider on the top and has a groove, or dots, fac-
ing up. A tip mounted upside down will produce a surface finish that looks like a record.
You should get at least 7 cuts per corner. However, tip life is affected by variables such as rust or ridges. In order to deter-
mine when to rotate tips, monitor rotor finish. If the rotor finish begins to look inconsistent, or feels rough to the touch, tips
should be rotated. Tips that are chipped or cracked should never be used.
Be sure that the tip pocket is clean before positioning the tip. Any foreign material pinched under the tip will cause problems.
NOTE 2: Use only Pro-Cut Cutting Tips (50-742). Although other tips may
fit the machine, only Pro-Cut tips have been specifically engineered in tan-
dem with the Pro-Cut lathe. Using a non-Pro-Cut tip may compromise lathe
performance and result in poor surface finish.
NOTE 1: The lathe has a powerful 1 hp motor which requires 20 amp ser-
vice. All extension cords must be at least 12 gauge and less than 25 feet;
drop light cords are not recommended.
CHECK CUTTING TIPS
STEP 1: MOUNT THE ADAPTER (2 Minutes)
MACHINING ROTORS
In just 4 steps in about 7-9 minutes, any tech can perform top-quality brake work.
Step 1: Mount the Adapter (2 mins.)
Step 2: Set up the Lathe (1-2 mins.)
Step 3: Adjust for Lateral Run-out (1 mins.)
Step 4: Make the Cut (3-4 mins.)
The First step is to choose the proper adapter. Most passenger cars require either the four (50-687) or
five lug (50-688) Direct Fit® adapter. Some larger passenger cars and smaller trucks use the (50-695)
adapter. For most trucks and vans, use the larger adapter (50-691) or the Asian / European variant, the
50-681. This fits 5, 6, 7, and 8-lug vehicles. See the adapter guide on pages 72-73 of this manual, or
use the adapter search on the Pro-Cut website for more specific information.
Once you’ve selected the correct size adapter, try each bolt pattern until you find the one that fits the ve-
hicle evenly. When possible, use the nuts provided with the machine. Hand tighten nuts with an open
box end wrench or a torque wrench in a star pattern. Do not use impact wrenches to mount adapters.
Nuts should be hand-tightened to 25-30 ft. lbs. Excess torque may damage the adapter.
Some vehicles require the use of a spacer (30-791 or 50-246) which are provided in the lathe package.
If the adapter doesn’t fit flush and square, use the spacer. Sometimes the holes in the spacer are not
needed as the entire bolt pattern will fit in the center of the spacer.
If the four steps are followed properly on each brake job, the Pro-Cut 9.2DRO RMS will operate accurately and efficiently.
