SP4012 SAFETY PRECAUTIONS
• DO NOT OPERATE THE ENGINE AT AN ANGLE
GREATER THAN 25° OR SEVERE ENGINE DAMAGE
WILL OCCUR. PROPER ENGINE OIL LEVEL MUST BE
MAINTAINED TO ACHIEVE MAXIMUM ANGLE OF
OPERATION OF 25°. (See Engine Owner’s Manual for proper
oil level.)
• Never allow spectators to stand and watch machine in operation
without proper hearing and eye protection and standing at a safe
distance. Loud noise and flying debris may cause severe injury.
• Do not operate around water, gas, power or phone lines. Check
with property owner or call utilities if not sure.
• Avoid fences and clear away other objects (i.e. sticks, stones,
metal, etc.).
• Be aware of the possibility of foreign objects imbedded in or
buried around the stump. Do not cut crosswise of roots above
ground to prevent roots being thrown.
• If unusual vibration occurs, stop engine immediately and correct
problem before continuing operation.
• Keep all guards in place and properly secured during operation.
• Keep all safety devices working properly and all other machine
parts in good working condition.
• Never leave the controls unattended while in operation. Be sure
machine is not capable of operation when left unattended.
• Stop engine and remove key when repairing or adjusting machine
or drive belts.
• Keep engine in good condition service as instructed in engine
manual.
• Do not touch engine while running or hot (serious burns may
result).
• Allow all machine parts to cool sufficiently before servicing or
making adjustments. Hot machine parts can cause severe burns.
• Do not run the machine without a complete number of teeth in the
cutter wheel tightened to the correct torque.
• Do not place machine in free wheel without first placing tongue
stake in the ground.
• Park machine on level surfaces only. Lower cutter head to the
ground and use wheel chocks to prevent unattended movement.
• Do not operate stump cutter in dark, dim lit, or concealed areas.
• Keep machine clean and clear of debris to eliminate fire hazard.
It is especially important to clean any oil or fuel spills to
prevent the danger of fire.
• Keep cutter wheel skirt guards in good condition to help control
chips during grinding.

SP4012 SAFETY PRECAUTIONS
ATTENTION:
The Carlton® Model SP4012 Stump Grinder CAN be overturned on steep inclines.
This can cause serious injury to operator and machine. DO NOT OVERTURN!
• Avoid steep side inclines when operating
this machine! The narrow design width
required in operating the model SP4012
in tight confines makes it susceptible to
tipping over sideways. Overturning this
machine can result in personal injury,
property damage and/or seizing the
engine.
USE CAUTION.
• Positioning the cutter wheel uphill and
as close to the ground as possible while
in transit will minimize the danger of
tipping over and maximize the
steadiness of the Model SP4012.
• When encountering a hill, the best
approach is straight up or straight down.
Avoid any side angles whenever
possible.
NEVER ALLOW INEXPERIENCED
PERSONS TO OPERATE THIS
MACHINE.

SP4012 DAILY CHECKLIST
• Check engine oil at dipstick. Take
reading with engine sitting level (see
photos). Add recommended oil (see
engine owners’ Manual) as required.
• Check fuel filter for debris or water.
• Replenish fuel tank with fresh fuel.
• Check condition and tightness of drive
belts. (See Servicing Belts) New belts
will stretch and become loose as
machine runs. Check belt tension often
when belts are new.
• Check for any loose, broken or missing
cutter teeth and pockets.
• Inspect bolts, hydraulic fittings, wiring
harnesses, hoses and equipment for
tightness, wear, or leakage. Replace if
necessary.
• Check air filters & precleaners. Inspect
dry air cleaners. Do not blow out or tap

MANUFACTURER
RECOMMENDED AIR FILTER
ONLY.
• Check hydraulic oil level. This Carlton
stump grinder is equipped with a gauge
that shows the level of oil and the
temperature of the oil. When filling the
tank with oil, the window of the gauge
will also fill with oil, as the level gets
higher in the tank. Never fill the oil tank
above the BLACK line at the top of the
gauge. Do not run the machine with the
oil level below the RED line at the
bottom of the gauge.
• Check condition of tires. Inflate to
proper pressure.
• Grease cutter wheel and jackshaft
bearings daily. Purge bearings until new
grease is seen.
