MACHINE START-UP
Do not start machine while drum is in
contact with the ground. Doing so can
cause the operator to lose control of the
machine, resulting in property damage
and/or personal injury.
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. Open the fuel cock on the
carburetor and then place the throttle lever at the
“Fast Idle” position. Start the engine, open choke
slightly to prevent ooding. Move throttle control
to open or run position when engine is warmed
up. Increase throttle to maximum operating
position (approx. 2800RPM) and close choke.
Before substrate removal, test run the drum
with cutters not touching the surface. If there is
excessive vibration, you need to re-balance the
cutter set-up, check bearing condition, and/or
make sure that the drive shaft is secured.
Corded “Engine Kill” Button (not available
on electric motor): In the event of a
malfunction or an accident (such as the
machine operator falling or losing footing), the
SPS10 is equipped with a corded “Engine Kill”
Button. Attach the end of the cord to the opera-
tor’s belt or wrist, and snap the clip into place
on the stop switch by raising the top of the
Engine Kill Button and inserting the clip into the
gap. If the operator becomes distanced too far
from the machine, the cord will detach from the
stop switch, and the machine will stop running.
Attatch to
operator
*NOTE: the Engine will not start without the
Corded Engine Kill’s clip securely in place.
CAUTION: The machine will still move with
the engine off.
IF THE ENGINE DOES NOT
START
1) Check Engine for proper gas and oil levels
(refer to Engine manual)
2) Check spark plug. Make sure the socket
areas are clean and clear of debris, and that
the proper gap is set. (Replace if needed).
3) Check Brown Electrical clip hanging on the
front of the engine and ensure that the
electrical wires are making contact within the
clip.
4) Turn the On/Off switch, on the front of the
Engine, to “On”.
5) Check Corded Engine Kill Button’s
Connections:
a) Make sure the Corded Safety Stop “C”
Connector is dipped properly.
b) Try switching the connection to the
opposite post (From letter “C” to letter “M”,
for example).
6) Engine may have tilted backwards. If so,
allow oil to drain after removing spark plug and
pulling starter cord several times.
*Engine repair and engine warranty
issues are handled directly
by your local engine service center.

SUBSTRATE REMOVAL
Warning: Should you desire to tilt the
machine, always tilt forward. Tilting the
machine backwards at any time will ood
the spark plug with oil and may cause
damage to your engine!
Adjust the height of the cutter drum with
the Hand Wheel and Cam Lever. (Turn the
hand wheel to raise the cutter drum off of the
substrate. Lower or raise the cam lever to
engage or disengage the drum 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 drum is positioned to
where only the cutters strike the surface,
and that the drum assembly never comes
into contact with the substrate. The cutter
tips alone should strike the surface (1/8”
to 1/4” maximum depth per removal pass on
new cutters).
The drum will not withstand substrate
contact. Contacting the removal surface
too deeply will cause premature wear to
cutters, shafts, drum and other
components!
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.
NOTE: Only use a forward motion when the
CM2150 or CM2550 carbide milling cutters
are used.
TIP: Positioning the machine over the
surface in many directions, as well as
dialing the hand wheel up or down can help
create desirable surface patterns.
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 drum above the substrate using the
hand-wheel and/or the cam lever. Stop the
machine only at the engine. Then close the
fuel cock to shut off the fuel supply.
The drum assembly must be removed daily
and inspected for drum wear, hole
elongation and possible weld separation.
Replace the cutter shafts and drum bushings
every 40 hours, or prior to any drum wear. If
the drum’s center holes are elongated, order
another SMITH cutter drum.

STORAGE
Shut off fuel valve and remove all fuel or
add fuel stabilizer. Start engine and run until
it stalls. Remove spark plug and pour two
ounces of motor oil into cylinder and slowly
crank the engine by hand to distribute oil to
prevent rust during storage. Replace spark
plug and store machine upright in a cool, dry,
and well-ventilated area.

MAINTENANCE CHECK LIST
Note: Make sure the ignition is in the OFF
position, and the spark plug is disconnected
before servicing
• Maintain proper engine oil and crankcase
levels.
Change every 25-50 hours
(see Honda manual).
• Clean spark plugs regularly, and set the
proper gap.
• Wash the air cleaner element in a non oil-
based solvent, then squeeze out residue.
Allow lter to dry before reinstalling in cleaner.
• Keep a coating of grease on the drive shaft
and threads for easy installation or removal,
and for longer hex bushing life.
• Grease the tilt lever, lower linkage. (Clean
dirt off of ttings before greasing.)
• Check all fasteners and re-tighten, since the
machine will vibrate the fasteners loose if they
are not secured. Use locktite.
This includes:
A) Both set screws (P/N 1010051) aligned on
hex shaft (P/N: 1065037) are torqued tight.
B) All three hex Bolts (P/N: 1010023) on
drum retaining plate (P/N: 1065054). Must be
aligned and tight.
• 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
cutters and drum rotate freely.
• Inspect and change drum bushings and
shafts every 40 hours, or when worn.

8. Loosen (do not remove) the four bolts (2
per side) that secure the motor mount plate
to the main machine frame.
9. Loosen the four bolts attaching the mo-
tor to the motor plate. After sufciently
loosening all four, slide the motor back all
the way to the rear. This will loosen the belt
sufciently to remove it.
10. Either cut or roll off the belt from the
pulleys. If you roll it off, move it over one
groove at a time on the upper and lower
pulleys to completely remove it.
8)
9)
11. Roll the new belt on one groove at a
time (two or single multi-groove belt) on
both the top and bottom pulleys.
12. Using the straight edge, lay it across the
lower pulley outer face and against the
upper pulley. They must be directly over
top of each other to insure long belt life. If
adjustment is required, align before
tensioning the belt.
13. After installation, use the 3/8” open-end
wrench to screw out the belt tensioning
jackscrew under the motor plate to tension
the belts to your desired tension. Do not
over-tension the belt.
14. After the correct tension is reached,
tighten the front motor plate securing screw
on the belt side with the 9/16” box end
wrench.
12)
13)
14)
15. Now from the front of the machine
observe the motor plate to machine
alignment. Tightening the belts with the
jackscrew tends to cause the right side of
the motor plate to lift higher than the left
side. By pushing down on the right front
side you can level the plate and then
tighten the front right screw to secure in a
level position.

retaining nut with a 9/16” wrench to prevent
it from turning.
17)
16)
18)
BELT ALIGNMENT
If the unit has premature belt wear, breakage
or pulley problems, the issue may be
incorrect alignment or excessive belt
tensioning. All pulleys must be aligned
directly above each other to ensure belt
integrity.
This includes possible timing belts used on
newer models. Incorrect alignment wears
the sides of the belts excessively and will
cause slippage.
1. Use a long straight edge (carpenters
square) to check alignment during belt
tensioning or belt replacement time.
2. By laying the straight edge against the
outer face of the lower pulley, the square will
extend up and rest against the outer face of
the upper (engine pulley). If not, move the
motor pulley in or out to obtain alignment.
3. If replacing pulleys (top or bottom) be sure
to place the pulley on the same plane as the
original one to ensure alignment.
