Made in the USA, this powerful, rotary style
pavement eradication machine takes the best
qualities from the Linax, TLR7 and PM ERASER
models and incorporates them into a versatile, full
featured, all powerful removing machine!
Designed to remove from 1” to over 24” wide
markings with a unique swivel wheel sweeping
removal method pattern, the LNX8 feathers the
substrate edges to eliminate the grooving pattern
or “ghost line”. Select your style of removal tool:
From our gentle action set of 3 steel pin cutters,
to our aggressive, 72 pin tungsten carbide, or our
NEW gentle abrading, 144 pin tungsten carbide
pin cutter set, diamond cup blades, mini bits and
more. See page 10 for more information.
You will obtain years of satisfying service when
your machine is properly used and maintained.
Please read completely this guide and parts list
manual to assure your REMOVAL SUCCESS.
If you have any questions about the operation of
your machine or would like to order replacement
parts, please contact your SMITH Dealer directly,
or
call SMITH at 1-800-653-9311
or [phone]
for the name of your local dealer.

BEFORE START-UP,
READ THIS..
Please read all operating instructions, including
the provided engine manual and be completely
familiar with your equipment before operating.
When in doubt, please contact SMITH
Manufacturing Customer Service for operational
details. This Owner’s Manual will guide you
through the removal process, from start to nish,
and show you how to care for your machine.
UNCRATING EQUIPMENT
When you uncrate your equipment, make certain
that the machine has not been damaged and
that all fasteners and guards are properly tight-
ened.
Your machine may not have been shipped as-
sembled with cutters and other accessories.
Assembly may be required.
REMEMBER: Only authorized, experienced and
properly trained personnel should operate this
equipment. Operating personnel should prac-
tice safety at all times and wear protective gear
(gloves, goggles, safety vests, ear plugs, steel-
toe shoes, etc.)
• Always wear protective equipment, including
ear protection and goggles.
• Never wear baggy or loose tting clothing that
can be caught on controls or moving parts.
• The surface preparator can emit ying par-
ticles and debris during operation. Never oper-
ate the machine near bystanders, animals or
children.
• Get acquainted with the machine’s controls,
and the Starter Box (pg. 4 & 5).
• Do not operate the machine in an explosive at-
mosphere, near combustible materials, or when
gas fumes may not be properly dispersed.
• Check power cord and plug for damage before
use.
• Never leave the machine unattended when
running, and you must hold onto the handle with
two hands when the cutter drum is engaged.
• Ensure that all guards are in place before the
machine is operated, since rotating and moving
parts will cause injury upon contact.
• Make sure that the machine is unplugged from
any power source before servicing.
• Always make sure that power
cord is UNPLUGGED when
storing machine.

HANDLE BAR ADJUSTMENT
The handlebars are equipped with a high-density vibration suppression material to minimize
operator fatigue and increase comfort level when operating equipment.
To adjust the handlebars to a new position for different height operators please follow these steps:
• Using a 9/16” (14mm) wrench or
socket, loosen the bolts on both
sides of the handlebars until the
handlebar moves freely. Take
care not to over-loosen the bolts
to keep them from falling out.
• Stand behind the machine and
lightly tap the handlebar to the
desired position
• Re-tighten the bolts to lock the
handlebars in the new position.

NOTE: Do not attempt to raise or lower the cam
lever by force. If it does not move effortlessly,
raise or lower the hand wheel until the cam lever
can be adjusted. Before substrate removal, test
run the machine with the spindle or disk attached
not touching the surface. If there is excessive
vibration, you need to inspect the cutter head to
make sure nothing is missing and it is balanced.
Also check for bearing condition, and/or make
sure that the drive belt is not damaged.
IF THE ENGINE DOES NOT
START
1) Make sure the motor is plugged into the
electrical source.
2) Turn the Start / Stop switch (on the Starter
Box) to “Start”.

Try cycling the starter switch back to off before try-
ing to restart the machine.
If the switch is in a roughly 10 O’clock position
and slightly loose, the breaker was tripped; in this
case turn the switch to the “Off” position until it
clicks into place before attempting to restart the
machine. To restart the machine turn the switch to
“On”.

SUBSTRATE REMOVAL
Adjust the height of the cutter head with the
Hand Wheel and Cam Lever. (Turn the hand
wheel to raise the cutter head off of the sub-
strate. Lower or raise the cam lever to engage
or disengage the cutter head after setting the
proper cutter depth.)
Set the depth of cut to allow the cutters to go
through only the materials to be removed. Make
certain that the cutter head is positioned to
where only the cutters strike the surface, and
that the spindle never comes into contact with
the substrate. 

Too much downward pressure only has negative
results. Try to remove materials in several passes
rather than one deep pass. Several tests will
show the best, most appropriate cutter impact.
Use a forward, backward and/or circular pattern
to achieve your desired nish.
TIP: Moving the machine over the surface in
many directions, as well as dialing the hand
wheel up or down can help create desirable
surface proles.
After several hours of practice, the operator
will become comfortable and should be able
to remove materials faster with enhanced
results.
When the job is completed, or the operator
wants to cease work, stop the engine by rst
lifting the cutter head above the substrate
using the hand-wheel and/or the cam lever.
Stop the machine only at the Starter Box.
Then unplug the machine from the power
source.
6 STEPS FOR LONGER
CUTTER LIFE
1) Protect the bearings with clean, oiled felt Seals*.
2) Do not pinch felt seals when installing cutters*.
3) Replace bearings and felt seals when worn*.
4) Change rubber bushings on engine plate and
spindle assembly after 50 hours use.
5) Never drop cam lever during grinding operations.

MAINTENANCE CHECK LIST
Note: Make sure the Starter Box is in the
OFF position, and the plug is disconnected
from any power source before servicing
• Grease the tilt lever, lower linkage. (Clean dirt off of ttings before greasing.)
• Check the Drive belt for wear, and adjust (tighten), or replace as required.
• Check that the pulleys are aligned properly to ensure the Drive belt is running true.
• Check wheel for wear and that they are rotating properly, replace if worn. Clean wheels
of material build-up.
• The inside housing must be clean, and remove any build-up from inside the cage so
spindle rotate freely.
• Check all fasteners and re-tighten, since the machine will vibrate the fasteners loose if they
are not secured. Use locktight.
• Every 40 hours of operation grease the two front axle bearings
