1.0 Introduction
With proper care and attention your Gruber Systems Mixer will provide maximum
performance and long service at minimum cost. We are sure that it will prove to be a
most valued asset to your Company.
Our interest in your equipment does not end with its sale. We are interested in
constantly maintaining contact with your Company. Should you have any questions or
problems, please contact us and we will be most eager to discuss these with you.
The purpose of this manual is to assist you in keeping your Vacuum Mixer in the
best possible operating and mechanical condition at all times. It is our endeavor to
manufacture the finest equipment available to the Cast Polyester Industry.
1.1 Application
The Gruber 1350 Blender is a mixing machined designed for the purpose of thoroughly
blending the components for Marble and Onyx Matrix. In general these are granular
fillers (ATH or Calcium Carbonate), Polyester or Acrylic resins up to 1500 cps, and
associated processing aid or pigments.
The machine includes a 24 inch dia. stainless steel vessel, with a relatively flat bottom,
and a blade with mixing blade designed to create high agitation to minimize mixing cycle
times. Depending upon your particular mixture’s specific gravity, the machine will
process approximately 350 Lb. per batch.
The mixing vessel is rotated to create the mixing action. The 3 hp. electric motor is
connected to a gearbox and drives the pot through a special turntable. The machine is
designed to be rotated in a counterclockwise (from top) direction. CHECK TAT THE
ROTATION IS CORRECT. DO NOT EVER INTERFERE WITH THE MOVING
BUCKET DURING PROCESSING. The pot can be easily lifted off of the turntable with
suitable lifting apparatus.
The specially designed blade is held stationary by an air powered retractable boom. It is
on a twist lock attachment to the boom, and can easily be removed for cleaning. Air is
supplied to the boom mounted pneumatic control valve. It is a lever type valve and
moves the boom up and down.

3.0 Public Law
3.1 Introduction
We recommend that the employer review the following codes to ensure employee
safety compliance:
J.I.C. Joint Industrial Council
O.S.H.A. Occupational Safety and Health Act 1970
N.F.P.A. National Fire Protection Association
Federal, State and Local Codes as applicable.
The practices and procedures described in the above codes and regulations are
intended to be implemented by the employee, but it is the responsibility of the
employers that their employees use these safety related work practices.
Instruct your employees to always be alert when they are working near exposed
energized parts and work situations where unexpected electrical hazards may
exist.
Instruct your employees not to reach blindly into areas that may contain energized
parts.
Employees shall not knowingly be permitted to work in areas containing exposed
energized parts or other electrical hazards while their alertness is recognizably
impaired due to illness, fatigue, under the influence of drugs or other reasons.
3.2 National Fire Protection Association Standards
N.F.P.A. – 70E covers electrical safety related work practices and procedures for
employees who work on, or near, or with electric circuits and equipment in the
work place.
The N.F.P.A. Code states that: the employer shall provide training to ensure that
all employees who are assigned to work on or near de-energized circuits or
equipment, understand the purpose of the disconnect lock out – tag out procedure,
and understand the requirements of the procedure that applies to their specific
work assignments.
7
N.F.P.A. – 70E also states that: employees shall not be permitted to work in an
area where they are likely to encounter electrical hazards unless they have been
trained to recognize and avoid the electrical hazards to which they are exposed.
N.F.P.A. – 70E also states: employees shall not be permitted to work on electric
circuit parts or equipment that have not been de-energized and locked out or
tagged out unless they are qualified and trained to use safe work practices.
The N.F.P.A. – 70 covers a wide range of employee safety related information,
including:
- Adequate illumination of space containing exposed energized parts
- Conductive articles of jewelry and clothing worn by employees exposed to
energized parts
- Conductive materials and equipment
- Insulated tools and equipment
The items listed here have been taken out of context and do not list all applicable
codes or standards. We suggest that your firm acquire the N.F.P.A. Codes for the
protection of all parties concerned.
Always disconnect power and lock main disconnect switch of machine before
doing any type of maintenance work.
The lock must prevent other personnel from connecting power to the machine
while maintenance work is being performed. A lockout device that permits
several padlocks to be installed is recommended.
The device provides safety to all parties working on this machine for accidental
start-up. This device is commercially available.
Before power is restored to the machine, all personnel in the area must be warned
to stand clear.
All affected employees must be notified to stay clear of the circuits and
equipment. There shall also be a visual verification that all employees are in the
clear.
8
Do not operate this machine without all safety guards in place. Guarding was
provided to reduce the exposure and hazards of moving components, which could
cause severe personal injury or death.
3.3 Equipment Lockout
To prevent personal injury or equipment damage when the machine is being
inspected or repaired, the following Lockout Procedure must be observed.
Machine Lockout must comply with the following provisions:
1. Every power source that can produce the movement of any machine part shall
be shut off at the closest power source.
2. The mechanical energy of all the parts of the machine must be reduced to a
zero energy state.
a. The opening of any pipe, tube, hose or the actuation of any valve must
not produce any movement that can cause injury.
3. Holding a machine member against gravity or a spring force by blocking
member, by suspicion, or by brackets or pins designed specifically for that
purpose are permissible if:
a. All machine members are at a zero energy state
b. All machine members are secured against accidental motion
4. A work piece or material supported or retained by the machine shall be
considered part of the machine.
5. Any power source that can produce a machine movement will be locked out
and identified by the person signing the lockout tag and working on the
machine.
6. When power sources have been locked out, a test must be performed to
ensure that machine movement cannot be initiated.
9
Machine Lockout Procedure
1. Personnel authorized to lockout equipment must have the necessary number
of locks to perform the job function.
2. Before proceeding with repair or inspection work, the employee must do the
following:
a. Physically disconnect all electrical power to the machine or lock out
the appropriate breakers or disconnect switches.
b. Lockout valves for air or hydraulic sources and bleed off any pressure
that could result in machine movement.
c. Physically block all machine members that can move from gravity or
spring pressure.
d. Test lock out for power by attempting to start machine controls.
e. Identify the Lock Out Condition with a tag on the electrical disconnect
and pneumatic shut off valve.
f. When the work is complete, restore the machine to its original state
and remove all tags.
g. Remove only the tags and lock you installed. If other personnel have
placed additional locks on the machine, do not disturb or remove them.
