Safety - During Use
● Safety equipment / controls.
Always operate the grinder with all safety covers, guards, and
barriers in place and in good working order, and all controls properly adjusted for safe operation.
● Controls.
Stay in the OPERATOR POSITION while actuating controls.
● Know how to stop.
Know how to stop the grinder quickly if needed by releasing the operator
presence bar. If this does not work, do the following in order until unit is stopped. 1. Push the stop
button on the control panel. 2. Use on/off switch on engine (or ignition switch on electric start
models). 3. Engage full choke by flooding the engine.
● "Kickback".
Machine can experience significant "kickback" when operating or first coming into
contact with the stump.
● Slipping/Falling.
Operating in wet or icy conditions could lead to losing your footing and slipping
or falling.
Safety - After Use
● Cool engine before storing.
Let engine cool for at least five minutes before storing. A hot
engine can be a fire hazard.
● Shut off fuel supply.
Make sure gasoline shut-off valve is in the OFF position.
● Prevent accidental starting.
When grinder is not in use, remove key from starter (electric
start engines) and secure in a safe location, or remove spark plug in order to ensure that grinder
cannot be started in a storage location or by untrained persons.
● Storage location.
Store the grinder in a dry location away from sources of heat, open flames,
sparks or pilot lights – such as water heaters, space heaters, furnaces, clothes dryers, or other gas
appliances – EVEN IF the grinder's gas tank is empty. Residual gasoline could ignite.
● Damaged.
Do not operate the grinder with damaged, missing, incorrectly adjusted, or broken
parts.
● Check for gas leak before starting.
After opening gasoline valve, smell for gas before
starting engine. If you smell gas, DO NOT start engine. DO NOT light a match. DO NOT flip on an
electrical switch. Exit area immediately and call fire department.
● Carbon monoxide exhaust.
The running engine gives off carbon monoxide, a poisonous gas
that can kill you. You CANNOT smell it, see it, or taste it. If you start to feel sick, dizzy, or weak while
using the grinder, shut off the engine and get to fresh air RIGHT AWAY. See a doctor. You may have
carbon monoxide poisoning.
● Other exhaust dangers.
This product contains or emits chemicals to cause cancer, birth
defects or other reproductive harm. Avoid inhalation of exhaust.
● Smoking/sparks.
Never smoke near the running grinder, and never operate near sources of
sparks or flames.
● Hot muffler.
Never touch hot muffler or hot exhaust manifold. Exhaust and engine parts can be
very hot and will burn you.
● Machine's moving parts.
Keep hands, feet, and apparel away from drive belts, cutter wheel,
and other moving parts. Never remove any drive belt or guard while the unit is operating. Contact
with belt or rotating teeth will cause personal injury.
● Refueling.
DO NOT refuel the engine until it has cooled at least 30 minutes.
● Malfunction during operation.
Always shut the machine off if any unusual noise or vibration
occurs.
● Vibration.
Overexposure to machine vibration on a daily basis may lead to circulatory or nerve
damage.
● Adjusting / repairing.
Always turn off grinder and remove spark plug or spark plug wire before
working on the grinder to prevent accidental starting.
● Cleaning the Jam:
If the machine is jammed, stop the engine and remove the sparkplug wire
before attempting to clear any jams in the unit. Stop all work, turn off stump grinder, unplug spark
wire and ensure the engine is turned off and cooled before performing any diagnostics or repairs.
Gasoline Safety
Gasoline is highly flammable and explosive. You can be burned or seriously injured when handling
fuel. Use extreme care when handling gasoline:
● Fuel outdoors.
Fill fuel tank outdoors – never indoors. Gasoline vapors can ignite if they collect
inside an enclosure. Explosion can result.
● Use approved container.
Never pump fuel directly into engine at gas station. Static charge
can build and ignite fuel. Use an UL approved fuel container to transfer gas to the engine.
● Running / hot engine.
A running engine is hot enough to ignite fuel. Never add fuel or remove
gas cap if engine is running or still hot. Stop the engine and allow to cool at least two minutes before
adding fuel.
● Heat / flames / sparks.
Keep sources of heat, flame, or sparks away while adding fuel.
● Don't fill to the top
DO NOT overfill the gas tank. Allow at least 1" of empty space below the fill
neck to allow for fuel expansion and operation on slopes.
● Don't fill to the top.
Do not fill the gas tank to the top. Gasoline may spill when operating on a
slope.
● Replace cap.
Replace gas cap securely before starting engine.
● Spills.
Clean up fuel spills immediately. Move grinder away from spilled fuel on the ground. Wipe
fuel off engine and wait 5 minutes for excess fuel to evaporate before starting engine. Gas soaked
rags should be disposed of properly.
● On skin / clothes.
If gasoline is spilled on your skin or clothes, change clothes and wash skin
immediately.
● Inspect fuel system.
Check fuel system on a regular basis. Look for signs of leaks, deteriora-
tion, chafed or spongy fuel hose, loose or missing fuel hose clamps, damaged fuel tank, or a defective
fuel shut-off valve. Do not start grinder until needed repairs have been completed.
● Gasoline storage.
Store gasoline in a cool, dry place in an UL-approved, tightly sealed container
away from children.
