Please read these instructions carefully

Caution
1. Servicing shall be in compliance with
applicable 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. 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.
3. Be careful when touching the exterior of
an operating brake. Allow sufficient time
for the brake to cool before disassembly.
Surfaces may be hot enough to be
painful or cause injury.
4. Do not operate brake with housing
removed. All moving parts should be
guarded.
5. 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.
6. Maintenance should be performed only
by qualified personnel familiar with the
construction and operation of the brake.
7. For proper performance and operation,
only genuine Stearns parts should be
used for repairs and replacements.
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.
