•
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 fluid 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 cardboard rather
than your hands. If injured, seek medical attention immediately to prevent serious infection or
reaction.
When replacing any part on your Industrial Tub Grinder, be sure to use only DuraTech authorized parts.

Fire Prevention
Grinding wood, hay, and other products in a tub grinder produces a large amount of potentially combustible material. The
risks of fire can be significantly reduced with proper operating and maintenance procedures. This does include frequent
removal of dust, debris, and other combustible materials.
Most of the products that are ground are dry and the grinding process can produce fine, dusty material. The grinding
process can produce heat and the spinning rotor will circulate air within the grinding chamber. For a fire to start, fuel,
oxygen and heat in sufficient quantity, must be present. During normal operation and with a properly maintained tub
grinder, the material being ground will move through the grinding chamber so quickly that it doesn’t have a chance to
heat up sufficiently to start a fire. Also, the rapid rate that a tub grinder can pile material will quickly smother small hot
spots that might occur during normal grinding operations. Keeping the material moving through the machine and across
the top of the rotor is important to keep frictional heating of the material to a minimum.
NEVER
leave the vicinity of the unit with the engine running
.
PROPER OPERATION OF THE TUB GRINDER:
•
Do not grind materials any finer than necessary. Finely ground materials will produce more dust and
increase the risk of fire. If finely ground materials are required, it is better to grind the materials coarse
first with large opening screens installed in the grinder and then regrind them to the desired consistency by
installing smaller opening screens in the grinder. Be especially cautious when grinding materials that can
burn easily.
