Warning!
If blade bolts are allowed to run loose, the obvious danger is for the bolt to come
completely loose, allowing the blade, bolt, and nut to be ejected from the cutter.
Tightening Blade Bolts (
continued
)
The second danger is that when the bolt is not sufficiently tight, the blade is allowed excess vertical
movement when it strikes an object, be it something it will cut or something into which it should not
come in contact. In this situation, the blade is being hammered against the blade carrier and flexed,
or bent, up around the edge of the blade carrier at least twelve (12) times per second, generally fifteen
(15) times per second. This situation will cause the blade to break from fatigue and to be ejected from
the cutter.
The third danger is that, while
the second situation is occurring,
the blade bolt is also hammering
the underside of the blade carrier;
the shoulder of the blade bolt beats
an indention around the blade bolt
hole into which the bolt shoulder
will fit. When this damage occurs,
the blade bolt will pull up into the
indention when the bolt is tightened,
causing the blade to jam so that it can
no longer pivot on the blade bolt. A
jammed blade will break either from fatigue or from catastrophic occurrence and will allow the blade to
be ejected. A blade carrier damaged in this manner must be taken out of service immediately. Repair
the blade carrier (contact Brown Mfg. Corp. for instructions) and replace the blades and blade bolts
before returning the machine to service.
All three of the described occurrences will cause the blades to break and be ejected. An
ejected blade can and will cause serious injury or death.
REMEMBER: Blades must pivot freely and blade bolts must be tight!
Proper Gearbox Lubrication
With the cutter sitting level, find and remove the combination vent plug/dip stick from the top of
the gearbox. Wipe the dip stick clean and reinsert. Then remove. Oil should touch the dip stick. If
not, add oil until it is no higher than 1/2” to 1” on the dip stick. Excess oil in the gearbox will be
exhausted through the vent plug/dip stick. Proper replacement oil is 85-140 weight gear oil, our part
number is T5-LUBE.
Make certain plug is replaced and tightened securely before operating.
