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.

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.

5.0 General Maintenance and Installation
5.1 Repairs
Before adjustments and repairs are started on the Gruber 1350 Blender, the
following precautions shall be taken as applicable:
(1) Motor and gearbox stopped and starting means rendered inoperative
(2) ON/OFF switch is in the "OFF" position.
(3) Follow appropriate lockout/tag out procedure.
5.2 Gear Reducer
The gear reducer on the 1350 blender is filled with the proper lubricant before it
is shipped from Gruber Systems factory. However, it should be carefully
inspected for evidence of oil leakage after it has been received. The blender
should never be turned on its side, or any position other than upright, or oil will
leak out of the vent plug. If this should occur, the gear reducer must be refilled to
the proper level (see refilling instructions).
To gain access to the gear reducer, it will be necessary to first remove the
turntable with the Allen wrench provided. Next remove sheet metal cover. It may
also be desirable to remove the sheet metal enclosure to make the wiring and
refilling more convenient.
The two leads in the three-phase motor that are labeled “thermostat” are used
when the unit uses a magnetic-type starter switch. These two leads are to be
placed in series with the stop button. When the motor overheats, the thermostat
will open, removing power from the coil of the magnetic starter.
Worm gear speed reducer lubrication
Installation and maintenance instruction
Reducers are designed for installation in several different positions, see mounting
position diagrams for your selected mounting position and note the proper
locations for the level and vent/fill pipe plugs. FILL AFTER ASSEMBLING
WITH MOTOR.
15

STEP #1 Remove the vent/fill plug and the proper solid level pipe plug.
STEP #2 Pour oil in the vent/fill plug hole. Stop pouring and insert the solid
pipe plug* in the level hole. You can also check the catalog for the proper amount
of oil required and pour in that amount without removing the level plug. A little
extra oil will not harm the reducer and is preferred to too little oil.
STEP #3 Replace the vent/fill plug in its proper location.
Recommended oil: Mobil Extra Hecla Super cylinder oil or equivalent.
To insure longer reducer life, the reducer should be periodically drained while
warm and refilled to the proper level with the appropriate lubricant. Under normal
conditions, it is recommended that the initial oil be drained, while warm, after the
first 100 hours of operation, again after 250 hours of operation, and thereafter at
intervals of 1000 hours. Consult your distributor or oil supplier for a lubricant that
conforms to the following A.G.M.A. specifications.
Ambient Lubricant Viscosity Range**
Temp. A.G.M.A SUS @ 210 F
15 F to 60 F 7 Compound 125-150
50 F to 125 F 8 Compound 150-190
For installations other than the temperature ranges stated above, or for other
special conditions, get advice from the factory and/or your oil supplier.
* A sealant on the pipe plug threads is recommended in addition to proper
tightening of the pipe plug in order to prevent leakage.
** Based on lubricants with viscosity index of 95 minimum.
