2009 DURATECH TUB GRINDER OPERATING INSTRUCTIONS
The amount of material in the tub can dampen or stop the object’s potential ight. Keeping the tub full will reduce the
risks. Filling the tub at least 1/2 full before engaging tub rotation will reduce the risk. Using a geyser plate can help
reduce thrown objects. A risk may arise when the tub is being emptied, such as at the end of the grind. Running the
engine at slower speeds when starting or nishing the grind will also help, especially slowing down when emptying
the tub. Keeping the tub covered with DuraTech Industries Tub Covers will also reduce the risk of potential injury or
property damage. Use of a Tub Cover will not reduce the area over which thrown objects may fall, but it does reduce
the percentage of objects thrown from the tub.
WARNING: To minimize the potential risk of injury or property damage, the operator must:
a) Place side B towards open areas, away from property and people.
b) Load the grinder from side A with a loader equipped with an enclosed cab.
c) Keep observers and unauthorized personnel out of the area.
d) Wear a hard hat, safety glasses, and ear protection at a minimum, and require that any other
persons in the area are similarly equipped.
e) If the optional tub cover is installed on the machine, the operator should keep the Tub Cover
over the tub as much as possible while grinding. While grinding, the Tub Cover should be
raised only when adding material to the tub, and then the Tub Cover should only be
raised enough to allow the new materials to be placed in the tub.
CAUTION: The stored up energy in the rotor causes it to rotate long after the clutch has been
disengaged. Before performing any maintenance on the machine or getting into the tub, be sure rotor
and all moving parts have come to a complete stop. Shut off engine and remove the key.
Before working on or near the Tub Grinder for any reason such as servicing, inspecting or unclogging the machine:
• Follow the normal shutdown procedure found on page 29 of this manual.
• If the unit is still attached to a towing vehicle, place the towing vehicle’s transmission in park and set the
parking/emergency brake.
• Relieve all pressure in the hydraulic system before disconnecting hydraulic lines or performing work
on the system. Make sure all connections are tight and the hoses and lines are in good condition before
applying pressure to the system.
WARNING: Hydraulic uid escaping under pressure can be invisible and have enough force to
penetrate the skin. When searching for a suspected leak, use a piece of wood or a piece of cardboard
rather than your hands. If injured, seek medical attention immediately to prevent serious infection or
reaction.
