SPECIAL PRECAUTIONS
1.
Do not climb on, or stand on the unit when it is turned by the P.T.O of the tractor. All moving
parts are guarded for your protection but foreign objects such as rocks and pieces of iron can be
thrown out of tub as it runs empty of material.
2.
Leave all shields and guards on the machine while operating. They are for your protection and
removal of them will hinder the operation of the machine. Warranty is void if the machine is
operated with any of the shields missing.
3.
The ROTO GRIND is designed to be turned at 1000 R.P.M. with tractor power take off. Do not,
under any circumstances, turn the mill over 1250 R.P.M. or serious damage could result to the
machine. Do not operate at 540 R.P.M. unless application is approved in writing from a Burrows
Ent. Inc. officer. Failure to operate at the correct R.P.M.’s will void warranty.
4.
The ROTO GRIND is designed to grind roughage materials either loose or baled. The machines
are equipped with twine guards and will keep almost all of the sisal twine from wrapping on the
rotor shaft if they are adjusted properly, however the shaft should be checked periodically for
twine build up and removed if any has accumulated.
Plastic twine should not be ground because it is not only non-digestible, it is more likely to wrap
on the rotor shaft. Any plastic twine build up will create heat and melt into a solid lug that can
only be removed by burning it off.
5.
In loose material, the ROTO GRIND will operate with more capacity if the size of the bites of
material being loaded is small enough to fit in the tub. Do not allow material to hang over the side
of the tub. This will cause a bridging effect and will slow up grinding.
6.
Do not attempt to grind foreign materials such as rocks, brick, dirt, sand, any type metal pieces or
products, tree branches over 3” in diameter, glass, or ceramics. These products can damage the
machine and voids warranty.
