Warning
Waste electrical products must not be disposed of with household
waste. Please recycle where facilities exist. Check with your local authorities
or retailer for recycling advice.
1) Work area safety
a) Keep work area clean and well lit.
Cluttered or dark areas invite accidents.
b) Do not operate power tools in explosive atmospheres, such as in the
presence of flammable liquids, gases or dust. Power tools create
sparks which may ignite the dust or fumes.
c) Keep children and bystanders away while operating a power tool.
Distractions can cause you to lose control.
2) Electrical safety
a) Power tool plugs must match the outlet. Never modify the plug in any
way. Do not use any adapter plugs with earthed (grounded) power
tools. Unmodified plugs and matching outlets will reduce risk of electric
shock.
b) Avoid body contact with earthed or grounded surfaces, such as
pipes, radiators, ranges and refrigerators. There is an increased risk of
electric shock if your body is earthed or grounded.
c) Do not expose power tools to rain or wet conditions. Water entering a
power tool will increase the risk of electric shock.
d) Do not abuse the cord. Never use the cord for carrying, pulling or
unplugging the power tool. Keep cord away from heat, oil, sharp
edges or moving parts. Damaged or entangled cords increase the risk of
electric shock.
e) When operating a power tool outdoors, use an extension cord suit
able for outdoor use. Use of a cord suitable for outdoor use reduces the
risk of electric shock.

2
f) If operating a power tool in a damp location is unavoidable, use a
ground fault circuit interrupter (GFCI) protected supply. Use of an
GFCI reduces the risk of electric shock.
3) Personal safety
a) Stay alert, watch what you are doing and use common sense when
operating a power tool. Do not use a power tool while you are tired or
under the influence of drugs, alcohol or medication. A moment of
inattention while operating power tools may result in serious personal
injury.
b) Use personal protective equipment. Always wear eye protection.
Protective equipment such as a dust mask, non-skid safety shoes, hard
hat or hearing protection used for appropriate conditions will reduce
personal injuries.
c) Prevent unintentional starting. Ensure the switch is in the off-position
before connecting to power source and/or battery pack, picking up or
carrying the tool. Carrying power tools with your finger on the switch or
energizing power tools that have the switch on invites accidents.
d) Remove any adjusting key or wrench before turning the power tool on.
A wrench or a key left attached to a rotating part of the power tool may
result in personal injury.
e) Do not overreach. Keep proper footing and balance at all times. This
enables bettercontrol of the power tool in unexpected situations.
f) Dress properly. Do not wear loose clothing or jewelery. Keep your
hair and clothing away from moving parts. Loose clothes, jewellery or
long hair can be caught in moving parts.
g) If devices are provided for the connection of dust extraction and
collection facilities, ensure these are connected and properly used.
Use of dust collection can reduce dust-related hazards.
h) Do not let familiarity gained from frequent use of tools allow you to
become complacent and ignore tool safety principles. A careless
action can cause severe injury within a fraction of a second.
4) Power tool use and care
a) Do not force the power tool. Use the correct power tool for your
application. The correct power tool will do the job better and safer at
the rate for which it was designed.
b) Do not use the power tool if the switch does not turn it on and off.
Any power tool that cannot be controlled with the switch is dangerous and
must be repaired.
c) Disconnect the plug from the power source and/or remove the battery
pack, if detachable, from the power tool before making any adjust-
ments, changing accessories, or storing power tools. Such preventive
safety measures reduce the risk of starting the power tool accidentally.

3
d) Store idle power tools out of the reach of children and do not allow
persons unfamiliar with the power tool or these instructions to
operate the power tool. Power tools are dangerous in the hands of
untrained users.
e) Maintain power tools and accessories. Check for misalignment or
binding of moving parts, breakage of parts and any other condition
that may affect the power tool’s operation. If damaged, have the
power tool repaired before use. Many accidents are caused by poorly
maintained power tools.
f) Keep cutting tools sharp and clean. Properly maintained cutting tools
with sharp cutting edges are less likely to bind and are easier to
control.
g) Use the power tool, accessories and tool bits etc. in accordance with
these instructions, taking into account the working conditions and
the work to be performed. Use of the power tool for operations different
from those intended could result in a hazardous situation.
h) Keep handles and grasping surfaces dry, clean and free from oil and
grease. Slippery handles and grasping surfaces do not allow for safe
handling and control of the tool in unexpected situations.
5) Service
a) Have your power tool serviced by a qualified repair person using only
identical replacement parts. This will ensure that the safety of the
power tool is maintained.
b) If the replacement of the supply cord is necessary, this has to be done
by the manufacturer or his agent in order to avoid a safety hazard.

SECTION 2
Setting Trim Length
The Case Trim Xpress is supplied with 10
different bushings covering a wide range
of popular bottleneck cases. Additional
bushings can be purchased for calibers
that are not covered by the supplied
bushings. Please refer to the bushing
chart on back for caliber information and
part numbers.
1. Select the proper bushing for the caliber you are trimming. Unthread the
bushing cap (pic 3). Under the bushing
cap you will find a compression spring,
this spring must be installed in order for
the trimmer to function correctly.
2. Place the bushing into the adjuster barrel
as shown (pic 4) with the bushing num-
ber facing you. Reinstall the bushing
cap and tighten.
3. Locate the Cutting Depth Adjustment
wheel (pic 5). Each white graduation
mark represents .001” increments.
Turning the adjustment
wheel clockwise will
DECREASE your cut-
ting depth (less material
removed). Turning the
adjustment counter-clock-
wise will INCREASE your cutting depth (more material removed). A viewing
window is located at the top of the adjustment wheel housing, this window
will allow the user to view the graduation marks to ensure a proper setting.
4. Measure a case to be trimmed, making
note of the untrimmed length. (pic 6)
TRIMMING TIP: Because the bush-
ing uses the shoulder of the case to
determine trim length, all cases should
be cleaned and sized before trimming
to ensure an accurate and consistent
result. If your cases have been sized at
3
4
5
6

6
different times there is a chance your size die setting could vary thus giving
the user inconsistent results.
5. Insert the case to be trimmed. Push the
case and bushing against the compres-
sion spring with even pressure until the
case bottoms out. (pic 7) Observe the
distance from the case mouth to the
cutter head. (pic 8) If the case mouth
IS contacting the cutter head, turn the
adjustment wheel clockwise until the cut-
ter is barely contacting the case mouth.
If the case mouth IS NOT contacting the
cutter turn the adjustment wheel count-
er-clockwise until the cutter barely touch-
es the case mouth.
TRIMMING TIP: when setting the initial
cutting depth make sure you have fully
compressed the spring; repeat this step
a few times, to ensure the proper initial setting.
6. Once you have your initial setting turn your adjustment wheel count-
er-clockwise one graduation mark. Turn trimmer to the highest RPM set-
ting and compress the case into the bushing with even pressure and trim.
TRIMMING TIP: Using even pressure each time you trim a case will help
the user achieve clean and consistent trim lengths each time.
7. Remove the case and measure your case again, compare that with the start
length of the case that you made note of earlier. Your case should be at
least .001” shorter.
TRIMMING TIP: Always trim at the highest RPM setting. If you observe
chatter on the case mouth, slowly adjust RPM down until chatter is gone.
8. Once you have measured the case, you can now set the adjustment wheel
the correct number of graduation marks in order to achieve your correct trim
length.
TRIMMING TIP: Here is an example of steps 5,6,7,8: .270 Win case with
untrimmed length of 2.546”. Initial setting completed, adjustment wheel is
turned one graduation mark, then trim a case. Trimmed case measures
2.545”. Turn adjustment wheel counter-clockwise 15 graduation marks (trim
to length for .270 Win is 2.530”). Trim case and measure. Your case should
now measure 2.530”. Your trimmer is now set to trim your .270 Win cases
to the correct trim to length of 2.530”. With some practice and using firm
7

even pressure each time you trim a case, you should be able to achieve
clean consistent trim-to lengths.
SECTION 3
Operating Instructions
1. The Case Trim Xpress can be mounted to your reloading bench. There are
4 mounting holes that can be used to directly mount the trimmer. The trim-
mer can also be used unmounted and hand held against the bench. The
trimmer is equipped with non-slip rubber feet that will help prevent the trim-
mer from sliding when in use.
TRIMMING TIP: You can use your hand to hold the rear of the unit as you are
trimming for added stability.
2. Verify that you have set your trim length, as described in Section 2.
3. Prior to operating your trimmer, the Chip Guard should be installed. With
the Chip Guard installed, it will allow the brass chips to collect in one area
keeping your bench clean.
To install the Chip Guard, place on top of
the Adjuster Barrel as shown and snap
into place. (pic 9)
4. Turn your trimmer on to the highest
RPM setting. Insert a sized case into
the Bushing. Using light, even pressure
move the case forward towards the cut-
ter. When the case makes contact with
the cutter, use firm pressure but do not “JAM” the case into the cutter. This
will cause rough, inconsistent cuts, which could damage the case or cutter
head.
TRIMMING TIP: Turn the case 180 degrees, and trim again to insure a clean
square cut.
5. Remove the case from the trimmer and measure your case again to ensure
proper trim length. It is recommended that you use an inside and an out-
side chamfer tool to remove any roughness on the case mouth.

SECTION 4
Care and Maintenance
1. Periodically remove the Adjuster Barrel and clean any brass shavings from
cutter head and shaft assembly.
2. Clean the Adjuster Barrel of any brass shavings. Remove the Bushing Cap
and clean the threads on the Bushing Cap and Adjuster Barrel.
3. Inspect and clean compression spring. Inspect and clean Bushings if neces-
sary.
4. Main body of trimmer can be wiped with a
damp clean cloth if needed.
5. The Case Trim Xpress is provided with a
lifetime carbide cutter head, under normal
use the cutter will give the user years of
clean, consistent cuts. In the event the
cutter head becomes damaged, it can be
changed easily.
6. To remove the cutter head, first turn the
Adjustment Wheel clockwise until the
Adjuster Barrel is free of the main body.
(pic 10)
7. Locate the set screw on the brass cutter
housing. (pic 11) Loosen set screw, and
remove cutter. Use caution when working
in the cutter head area, the carbide cutter is
very sharp and can cause injury.
8. To install a new cutter head, first locate
the “flat” on shank of the cutter head. (pic
12) The “flat” should be inserted so that
the set screw will contact it when tightened.
Tighten set screw firmly.
9. Reinstall Adjustment Barrel by turning
the Adjustment Wheel counter clockwise.
Make sure that the Adjuster Barrel is lined
up correctly in main body. You will notice
a slot cut on the bottom of the Adjuster
Barrel, (pic 13) this needs to be aligned
with the pin at the bottom of the main hous-
ing.
A light coat of oil can be applied to the
Adjuster Barrel threads and Bushing Cap.

10. If the Case Trim Xpress is stored in a humid environment or for a length of
time you can add a light coat of oil to the Adjuster Barrel and cutter head to
prevent corrosion.
The internals of the Case Trim Xpress do not require any maintenance, there-
fore the housing should not be opened for any reason. Opening the housing
may cause damage to the unit, and will void your warranty. If the Case Trim
Xpress requires repair please contact Lyman Products Customer Service at
1-800-225-9626 to set up a return for service.
Recommendation for the operator to wear hearing protection.
_ that the declared vibration total value(s) and the declared noise emission val-
ue(s) have been measured in accordance with a standard test method and may
be used for comparing one tool with another;
_ that the declared vibration total value(s) and the declared noise emission val-
ue(s) may also be used in a preliminary assessment of exposure.
_ that the vibration and noise emissions during actual use of the power tool can
differ from the declared values depending on the ways in which the tool is used
especially what kind of workpiece is processed; and
_ of the need to identify safety measures to protect the operator that are based
on an estimation of exposure in the actual conditions of use (taking account of
all parts of the operating cycle such as the times when the tool is switched off
and when it is running idle in addition to the trigger time).
Recommendation that the tool always be supplied via a residual current device
having a rated residual current of 30 mA or less.
