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

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 operate 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.

* Certain multiple friction disc model numbers require a single stabilizer clip (D1) added to each friction disc. If your particular brake model has this clip

on the discs, as received, it must be replaced whenever the friction disc is replaced. This clip is included as part of the friction disc kit 5-66-8462-00.

** Close coupled brakes are identified by an 8 in the 8th digit. Example: 1-056-XXX-8X.
