DANGER: Never operate any machinery while under the influence of drugs, alcohol or
impairing prescription drugs.
DANGER: Do not operate the STK if any oil leaks are present. Hydraulic oil gets hot and is
under extreme pressure, which will burn and cut. If injected with hydraulic oil seek medical
attention immediately.
DANGER: Stay clear of moving parts. Dig chains, tracks, booms, lift cylinders and other
moving parts can cut off fingers, arms, legs and other body parts. Contact with moving parts
while the machine is operating will cause death or serious injury.
DANGER: Never attempt to clear debris from the chain or auger while the engine is running or
capable of running.
DANGER: Only operate outdoors and avoid breathing engine exhaust fumes. Engine exhaust
contains toxic carbon monoxide gas. Breathing it can cause unconsciousness and death.
DANGER: Never permit anyone to ride, sit or stand on the STK. The STK is NOT intended to
carry a driver or passenger. Carrying people on the STK will result in death or serious injury.
DANGER: Never operate the STK with any guards or flaps removed.
DANGER: Do not leave the STK unattended with the engine running. Always turn off the
engine and never leave the STK where non-authorized persons have access to the machine.
WARNING: Wear appropriate personal protective equipment, safety glasses, ear plugs, hard
hat, gloves, and boots. DO NOT wear loose clothing, jewelry, long hair or anything that may
get caught in a moving part.
WARNING: Stay clear of the front of the STK while in operation. Cease operation if anyone
comes within 30 feet of the front of the STK.
WARNING: DO NOT operate the STK on steep grades. On any grade keep the boom as low
as possible. Never stand downhill of the STK.

SAFETY INSTRUCTIONS OVERVIEW CONTINUED
We recommend having a fire extinguisher capable of extinguishing class A, B & C fires in the
operating area.
WARNING: Do not operate the STK near any source of flammable dust or vapor. Sparks from
the engine can cause a fire or explosion in a flammable atmosphere.
WARNING: Shut off engine and allow it to cool before refueling. Sparks and heat from the
engine may ignite fuel.
Work site preparation:
DO NOT dig until all utility lines have been identified and authorized to dig. Identify and remove or
avoid all safety hazards. Ensure worksite is well lit. Keep others away from the STK while operating.
Select job sites free from bystanders. If the job site is near a road or a pedestrian pathway and cannot
be moved, warn and divert both motorized and pedestrian traffic. As appropriate and legal, use traffic
flag personnel, signs, cones and lighting devices to ensure safety. Diverting traffic and working in
congested public areas may require permits or other such legal considerations. It is your
responsibility to know and follow all applicable laws.
Contact with underground utilities:
WARNING: If you hit any underground utility line or pipe immediately evacuate the area and
call 911 (emergency services). There are numerous types of dangerous underground utilities.
IF AT ANY POINT AND FOR ANY REASON YOU DO NOT FEEL CONFIDENT ABOUT
OPERATING THE STK OR RECOGNIZE THAT YOU CANNOT SAFELY OPERATE THE STK,
STOP IMMEDIATELY. RELEASE THE TRENCH DIG CHAIN CONTROL LEVER, TURN OFF
THE ENGINE AND CONTACT THE STK OWNER.
