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.  
Important  
Please read these instructions carefully  
before servicing your Stearns brake. Failure  
to comply with these instructions could cause  
injury to personnel and/or damage to property  
if the brake is serviced or operated incorrectly.
