Operating this Stump Grinder safely is necessary to prevent or minimize the risk of death or serious injury. Unsafe operation can
create a number of hazards for you. Always take the following precautions when operating this Stump Grinder:

Your Stump Grinder is a powerful tool, not a plaything. Exercise extreme caution at all times. The machine is designed to
grind stumps. Do not use it for any other purpose.

Know how to stop the Stump Grinder quickly; see “stopping the engine” in chapter 3.

Never operate your unit on a slippery, wet, muddy, or icy surface. Exercise caution to avoid slipping or falling.

See manufacturer’s instructions for proper operation and installation of accessories. Only use accessories approved by DR
Power Equipment.

Never use the machine without ensuring that all guards and shields are in place.

Never, under any conditions, remove, bend, cut, fit, weld, or otherwise alter standard parts on the Stump Grinder. This
includes all shields and guards. Modifications to your machine could cause personal injuries and property damage and will
void your warranty.

Allow only one person to operate the Stump Grinder at any time.

If the machine should start making an unusual noise or vibration, shut down the engine, disconnect the spark plug wire,
keeping it away from the spark plug to prevent accidental starting, wait 5 minutes, then inspect for damage. Vibration is
generally a warning of trouble. Check for damaged parts and clean, repair, and/or replace as necessary.

Never tamper with safety devices. Check their proper operation regularly.

Before performing any maintenance or inspection procedure on the Stump Grinder, release the throttle lever first and then
release the operator presence lever, turn the ignition switch to “off”, remove the spark plug wire and keep it away from the
spark plug.

Never allow people who are unfamiliar with these instructions to use the Stump Grinder. Allow only responsible individuals
who are familiar with these rules of safe operation to use your machine.

Never overload or attempt to grind material beyond the manufacturer’s recommendation. Personal injury or damage to the
machine could result.

While using the Stump Grinder, don't hurry or take things for granted. When in doubt about the equipment or your
surroundings, stop the machine and take the time to look things over.

Never operate the machine when under the influence of alcohol, drugs, or medication.

Use the machine only in daylight.

Stay alert for hidden hazards or traffic.

Keep all nuts and bolts tight and keep the equipment in good operating condition.
