1 Safety Considerations
1-1 Safety Guidelines
Our granulators are designed to provide safe and reliable operation
when installed and operated within design specifications, following
national and local safety codes.
To avoid possible personal injury or equipment damage when
installing, operating, or maintaining this granulator, use good
judgment and follow these safe practices:
;LEARN AND OBEY your company’s safety policy regarding
granulating equipment.
;MOVING OR LIFTING THE GRANULATOR: Although
our equipment is built and engineered for great ruggedness in
operation, care must be taken when moving the machine along
the floor or lifting it. Damage may occur to sheet metal covers,
electrical cabinets, or small brackets if pressure is applied to
them when moving the granulator. When lifting the granulator,
be certain of total machine weight and the capability of the
lifting equipment. (See the Granulator Specification Sheets for
machine weights and dimensions.)
;GRANULATOR LOCATION: Adequate area for routine
maintenance should be provided in order to open the machine
for knife, screen, or cleanout service. Proper service area
clearances also should allow people who are working on the
machine to be clearly visible to others, thereby reducing the
potential safety hazards.
;SAFE HOUSEKEEPING: The work area must be kept clean
and uncluttered during periods of operation or maintenance. No
hand tools or other metal objects should be left on or around
the machine. Any tools or other metal objects which
mistakenly fall into the hopper feed opening can cause severe
damage to internal cutting chamber and screen chamber
components.
;SAFETY GLASSES OR A FACE SHIELD MUST
ALWAYS BE WORN when servicing or operating the
machine. Although our machines are designed for the
maximum in flyback control, caution must be used when
operating near the hopper feed opening in order to guard
against unexpected material flyback.

;EAR PROTECTION may be required when operating the
machine during granulation of very hard or noisy materials.
The Occupational Safety and Health Act of 1970 has
established guidelines for Permissible Noise Exposures (OSHA
1910.95) that should be followed.
;NEVER attempt to operate the granulator unless it is fully
assembled with all guards and interlocks in place and
functional.
;OBSERVE all danger, warning, caution and safety labels on
the equipment.
;Upon completion of any machine maintenance, be certain ALL
SAFETY GUARDS AND COVERS are securely and
properly fastened prior to resuming machine operation. All
fasteners must be in place and properly tightened. ANY
SHORTCUTS MAY RESULT IN INJURY TO
PERSONNEL OR DAMAGE TO EQUIPMENT.
;NEVER wear any loose fitting clothes, neckties, or dangling
items such as earrings, belts, or shoestrings. Jewelry, such as
wristwatches, bracelets, or rings should NEVER be worn. Long
hair must be tied back or placed in a tight fitting hairnet.
NEVER lean against or rest hands or feet on the granulator
when it is in operation or open for maintenance. NEVER stand
on the granulator when it is in operation.
;ROTATION OF MOTORS: All rotating items in the
granulator are clearly marked on the machine. Always check
for proper rotation of motors.
;ELECTRICAL GROUNDING: All electrical equipment on
the granulator must be grounded in accordance to all local
codes and Article 250 of the National Electric Code.
;ALWAYS DISCONNECT AND LOCKOUT the main
electrical power to the granulator before performing any
service.
;SAFETY INTERLOCKS MUST NOT BE BYPASSED.
The mechanical and electrical safety interlocks ensure the
safety of personnel. They should never be tampered with or
removed for ANY reason. They should be checked frequently
by a qualified mechanic for proper operation.
;NEVER modify the machine configuration or any individual
component without written consent from Cumberland
Engineering Corp.
