Important
Please read these instructions
carefully before installing,
operating, or servicing your
Stearns brake. Failure to comply
with these instructions could cause
injury to personnel and/or damage
to property if the brake is installed
or operated incorrectly. For
definition of limited warranty/
liability, contact Rexnord
Industries, LLC, Stearns Division,
5150 S International Dr, Cudahy,
WI 53110, (414) 272-1100.
Caution
1. Installation and servicing must
be made in compliance with all
local safety codes including
Occupational Safety and
Health Act (OSHA). All wiring
and electrical connections must
comply with the National
Electric Code (NEC) and local
electric codes in effect.
2. Do not install the brake in
atmospheres containing
explosive gases or dusts.
3. To prevent an electrical
hazard, disconnect power
source before working on the
brake. If power disconnect
point is out of sight, lock
disconnect in the off position
and tag to prevent accidental
application of power.
4. Make certain power source
conforms to the requirements
specified on the brake
nameplate.
5. Be careful when touching the
exterior of an operating brake.
Allow sufficient time for brake
to cool before disassembly.
Surfaces may be hot enough to
be painful or cause injury.
6. Do not operate brake with
housing removed. All moving
parts should be guarded.
7. Installation and servicing
should be performed only by
qualified personnel familiar with
the construction and operation
of the brake.
8. For proper performance and
operation, only genuine
Stearns parts should be used
for repairs and replacements.
9. After usage, the brake interior
will contain burnt and degraded
friction material dust. This dust
must be removed before
servicing or adjusting the
brake.
DO NOT BLOW OFF DUST using
an air hose. It is important to avoid
dispersing dust into the air or
inhaling it, as this may be
dangerous to your health.
a) Wear a filtered mask or a
respirator while removing dust
from the inside of a brake.
b) Use a vacuum cleaner or a soft
brush to remove dust from the
brake. When brushing, avoid
causing the dust to become
airborne. Collect the dust in a
container, such as a bag,
which can be sealed off.

Warning!
Any mechanism or load
held in position by the brake
should be secured to prevent
possible injury to personnel or
damage to equipment before any
disassembly of the brake is
attempted or before the manual
release knob or lever is operated
on the brake.
Use this sheet with the 1-081-x000 and 1-082-x00 series service booklets which can be found at
www.stearns.rexnord.com.
The solenoid plunger must be restrained in the solenoid frame (Picture A) before unbolting the support plate from the
endplate. Otherwise, the lever arm will rapidly move along the sector gear with a rapid snap action and the support
plate will not re-mount to the brake and disc pack problems may occur.
The manual release can also be pulled out to engage
the solenoid lever arm and move the plunger into the
frame.

frame of a new brake.
