ACCEPTANCE FROM TRANSPORTATION CARRIER

WWW.PROCUTUSA.COM PG / 15
Read, understand and follow the safety and operating instructions found in this manual. Know the limitation and hazards
associated with operating the machine.
SAFETY INSTRUCTIONS
1.
SPECIAL PRECAUTIONS: The Pro-Cut X9D brake lathe was designed to machine the portions of the brake disc that come
in contact with the friction material. When used according to the instructions herein, this lathe will perform satisfactorily
within the work piece size range designed for this model. During the machining operation, the work piece rotates. Be espe-
cially cautious of rotating spokes and mounted accessories. During machining, material removal may cause a sharp edge
to be generated, where a chamfer or radius previously existed. Use care in handling machined parts.
GROUNDING THE MACHINE: In the event of a malfunction or breakdown, grounding provides a path of least resistance for
electric current to reduce the risk of electric shock. The lathe is equipped with an electric cord having an equipment-
grounding conductor and a grounding plug. The plug must be plugged into a match outlet that is properly installed and
grounded in accordance with all local codes and ordinances. Do not modify the plug provided. If the plug will not fit the
outlet, have the proper outlet installed by a qualified electrician. If repair or replacement of the electric cord or plug is nec-
essary, do not connect the to a live outlet until repairs are performed. Check with a qualified electrician or service personal
if the grounding instructions are not completely understood, or if in doubt as to whether the lathe is properly grounded.
EXPLOSION RISK: This machine generates internal sparks. Do not use at less than 18” [0.46m] above grade level, and never
use below grade level. Work area should be well ventilated and free of explosive funes.

PG / 16 800.543.6618
USE PROPER EXTENSION CORD: Use only 3-wire extension cords that have 3-prong grounding plugs and 3-pole recep-
tacles that accept the lathe’s plug. Repair or replace damaged or worn cord immediately. Make sure your extension
cord is in good condition. When using an extension cord, be sure to use one that is 15’ or less and 14ga or heavier (i.e.
12ga). An undersized cord can cause a drop in line voltage resulting in a loss of power and overheating.
EYE SAFETY: Wear an approved safety face shield, goggles, or safety glasses. (Ordinary eyeglasses are not safety glasses
and do not provide the degree of protection necessary.)
RESPIRATORY SAFETY: If the operation or area is dusty a face or dust mask should be used.
PERSONAL PROTECTION: Before operating the machine, remove tie, rings,watches and other jewelry, and roll up sleeves
above the elbow. Remove all outer loose clothing and confine long hair. Protective type footwear must be worn. Hearing
protectors must be used where noise exceeds the level of exposure allowed in Section 1910.95 of the OSHA Regula-
tions. DO NOT WEAR GLOVES.
DO NOT USE LATHE IN DANGEROUS ENVIRONMENT: Don’t use the lathe in damp or wet locations, or expose the lathe to
rain. Keep the work area well lighted.
DO NOT OVERREACH: Maintain a balanced stance and keep your body under control at all times.

HAND SAFETY: Keep hands away from moving parts when the machine is under power. Never clear chips or debris when
the machine is under power and never use your hands to clear the chips. Never use compressed air to clean machine;
use only a soft bristle brush or vacuum cleaner.
MACHINING PREPARATION: Tighten all appropriate locks before operating the lathe. Be sure work piece is secured.
Remove adjusting keys and wrenches. Be sure to check to see that all adjusting wrenches are removed from the lathe
before turning the machine on.
CHECK DAMAGED PARTS: Before further use of the lathe, a guard or other part that is damaged should be carefully
checked to determine if it will operate properly and perform its intended function. Check for alignment of moving parts,
binding of moving parts, breakage of parts, mounting, & any other conditions that may affect the lathe’s operation. A
guard or other part that is damaged should be properly repaired or replaced.
MAINTAIN TOOLS WITH CARE: Keep tools sharp and clean for best and safest performance. Follow instructions for lubri-
cating and changing accessories.
NEVER STAND ON LATHE: Serious injury could occur if the lathe is tipped or if the cutting tool is unintentionally con-
tacted.

MACHINE CAPACITY: Do not attempt to use the machine for other than car or truck discs, or for operations for which the
machine was not intended.
CARELESS ACTS: Give the work you are doing your undivided attention!
Disconnect Electrical Power before performing any service, maintenance, or changing of accessories or adapters.
JOB COMPLETION: If the operator leaves the machine area for any reason,the machine should be turned off, and the
spindle brought to a complete stop before the operator departs. In addition if the operation is complete, the operator
should clean the machine and work area. NEVER CLEAN THE MACHINE WITH THE POWER ON.
REPLACEMENT PARTS: Use only Pro-Cut replacement parts and accessories, risk of injury may result in accessories other
than those recommended are used.
MISUSE: Do not use the machine for other than its intended use. If used for other purposes, Pro-Cut International, LLC,
disclaims any expressed or implied warranty, and holds itself harmless for any injury or loss that may result.

The X9D Multi-Speed Lathe has a feed rate of .005” [.127mm] per revolution and a variable spindle speed.
Choose spindle speed based on the size of the work piece, slower for larger diameter parts.
75-80% power may also give a better surface finish. For some trucks with speed-sensitive locking axles, you may
need to reduce the speed to 50% to stay below lock-up rpm.
No guarantee can be made for inserts not purchased from Pro-Cut, as insert corner radius, relief angle, material
composition and edge preparation can have a strong effect on cutting quality, insert lift, and tendency of the work
piece to vibrate. Always use Genuine Pro-Cut 50-778 inserts for best results.
The maximum recommended depth of cut is 0.012” / 0.3mm per insert.
X9D MULTI-SPEED BRAKE LATHE OPERATION PROCEDURES OPERATION

PG / 20 800.543.6618
VEHICLE PREPARATION
Before lifting the vehicle, the front wheels should be straight and the parking brake should be off, with the
transmission in neutral, and the traction control turned off.
NOTE: Remember to index mark rotors before removing them so you
can be sure they are returned to the same positions on the hub.
1. Raise the vehicle according to the lift manufacturer’s instructions. Raise until the wheel hub is about belt level.
2. Check wheel bearings for damage or excessive play. If this or any other wheel service is required, it should be performed
before match-machining the rotors as loose or damaged bearings will keep the lathe from doing the most accurate job possible.
3. Remove the wheels. Remove the brake calipers and suspend them out of the way of moving parts such as half shafts and
CV joints using the yellow S-hooks provided (pn 37-034). Be sure to remove all wheels that may turn when the lathe is
turned on.
4. Use Pro-Cut part number 37-996 or 37-997 wheel hub cleaning kit, or other suitable wheel hub cleaning tool to remove rust
or debris. Clean all material from the mounting area.
5. The rotor on the side of the vehicle that is not to be machined should be marked and removed if it is free on the hub or
secured with at least 2 lug nuts. Match marking the rotors to the hub is very important.
6. Use a micrometer to measure rotor thickness and determine how much material may be removed from the rotor by com-
paring to brake spec. Visually inspect for deep rust or grooves. This inspection will help determine the depth of the cut.
