1-4 Warnings and Precautions
Our shredders 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 shredder, use good judgment and follow these safe practices:
LEARN AND OBEY your company’s safety policy regarding shredding equipment.
MOVING OR LIFTING THE SHREDDER: 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 shredder. When lifting the shredder,
be certain of total machine weight and the capability of the lifting equipment. (See the
Shredder Specification Sheets for machine weights and dimensions.)
SHREDDER 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 that mistakenly fall into the hopper feed
opening can cause severe damage to internal cutting chamber, rotor and screen 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 shredding 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 shredder 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

Chapter 2: Functional Description
2-1 Models Covered in This Manual
This manual provides operation, installation, and maintenance instructions Conair Shredders of the
SHH, SHX, SFH, and SFX series with the Wide Open Access option. Contact Conair Service
(800-458-1960) for the user guides for shredders without the Wide-Open-Access shredders.
2-2 General Description & Typical Features
The various Wide Open Access shredders are designed for processing wood, plastic, rubber, carpet,
and paper materials. The shredder reduces material to approximately 1 to 4 inches (25 to 100 mm)
when using the optional discharge screen. For plastic applications when the shredder is combined
with a granulator (stacked 2-stage or in-line with conveyors) output material sizes can range from
1/8 to 1/2 inches (3 to 13 mm). The shredder can average 150% of its stated throughputs without
heavy power consumption loads (typically seen when using a granulator alone).

13
In-feed Hopper
The grinding material in-feed moves through an in-feed hopper so the material is delivered
correctly and safely. The grinding material can be fed into the shredder using many methods.
Typical in-feed options include manual in-feed of the shredding material directly into the hopper
with or without the help of an additional in-feed device or automatic in-feed of the shredding
material with an additional in-feed device (i.e. conveyor belt).
Discharge of Grinding Material
The shredded material is usually discharged into a box; an available option is discharge with a
conveyor. Shredded material is optionally classified thru a discharge screen.
Rotor and Cutters
The material is ground between the cutters assembled on the rotor and the bed knives, which are
mounted in a fixed position on the machine’s lower section. All rotors are equipped with square
cutters; these cutters make light work of the heaviest pieces. The cutters have four corners so they
can be easily turned once a corner has worn out. The design of the rotor has a significant influence
on the quality of the grinding process and its results. The rotor construction, the type of knife
mounting, and the number of cutters have all been exactly matched to the allocated tasks of the
machine.
The rotor is accessible after opening the rotor doors. The rotor is arranged on roller bearings,
which are located outside the cutting chamber. Gearbox is attached to the rotor axis and rotational
energy is derived from an electric motor. The electric motor is connected to the gearbox either
directly or with pulley driven belt drive.

14
Ram
The ram provides force necessary to introduce shredding materials to the cutting rotor. The ram is
moved by pressure from hydraulic cylinder. The ram action is controlled by PLC logic. The ram
uses spring loaded wipers on all sides to contain shredded materials inside the cutting chamber.
Drive
The drive consists of either a belt connected pulley mounted to parallel shafted gearbox or a direct
driven right-angle gearbox. In either case an over-torque limiting clutch is mounted between the
electric motor and the gearbox. The design of the drive provides enough horsepower to effectively
shred the appropriate materials; the over-torque limiting clutch provides protection to the gearbox
above the required horsepower for shredding materials. The clutch operation is monitored at all
times with high-speed counter sensors. Both drive designs use a rigid torque arm to offset gearbox
loading.

15
Hydraulic Power Unit
The hydraulic power unit provides hydraulic pressure, velocity, and directional control to the
hydraulic cylinder(s) that control the ram action. A typical hydraulic power unit consists of
electrical motor, hydraulic pump(s), directional solenoid valve(s), return filter, temperature/level
switch, and pressure transducer.
Control Panel
The control panel provides logic control for the main rotor motor and hydraulic system. The
various input sensors and limit switches from the shredder and hydraulic power unit provide
feedback to the programmable logic controller (PLC) thus producing machine functionality.
Wiring from the control panel will connect to the main rotor motor, main machine junction box,
and hydraulic power unit junction box. A typical control panel consists of operator interface touch
screen, main disconnect, and emergency stop push button; further details of functioning
components can be found in the appendix of this manual or within electrical schematics provided
with the shredder at the time of shipment.

16
2-3 Safety Features
Protective Devices
The machine must never be operated without the following protective devices or with faulty or
manipulated protective devices.
Rotor/Screen door safety device
The shredder must only be operated if the rotor door(s) are closed and the lock is tightened –
otherwise, the safety switch will be activated. If the rotor door(s) are opened during operation, the
safety switch will be tripped, and the machine will shut off.
Hopper
The input opening of the machine is elongated with an infeed hopper. The hopper is bolted in place
and must be installed at all times for safe operation of the machine.
Splash guard
The input opening of the machine is optionally provided with a splash guard to prevent fly-out in
case the ground material is introduced directly in the feed hopper.
Safety Markings
Safety markings are attached to the machine. If one of these markings becomes detached or is no
longer recognizable, the marking must be replaced. New markings can be ordered from the
manufacturer; please contact Conair Service (800-458-1960).
Emergency Stop Button
The machine must only be operated with the installed Emergency Stop buttons. One Emergency
Stop button must be mounted onto the control cabinet and a second onto the shredding material in-
feed.
In case of an emergency, immediately press one of the Emergency Stop buttons.
CAUTION! The Emergency Stop button must be activated in all situations in which injury or
damage could result! DO NOT service the blades or material in-feed while machine is
operational!

Chapter 3: Installation
The following listed installation information should be observed as closely as possible to ensure
proper machine operation.
3-1 Lifting and moving
The machine must be handled with care whenever being moved. This is to prevent damage to any
part of the machine. The machine is provided with lifting lugs which should be used whenever the
machine is being moved. It is recommended that the machine be lifted only in this manner.
3-2 Foundation
The machine must be secured to a firm foundation that is flat. This foundation must be of a
material that will provide a firm rigid support for the machine.
3-3 Leveling and securing
The machine should be positioned in a level condition. It should be secured to the foundation
through the holes provided in the base or using toe clamps with spacers for machines without holes.
Fastening should be secure enough to prevent machine movement during operation. Shim machine
to ensure that base is not in a strained condition.
A 1/8” to 1/4” thick rubber strip may be used between foundation and machine base to reduce
vibration.
Recommended fastening instructions for toe-clamp are as follows:
1. Use hammer drill with concrete bit to drill 7/8” diameter holes at depth of 5” (locate holes
using drawing supplied with this manual)
2. Cut 3/4” threaded rod into 8” lengths, one for each hole (more length will be required if using
shims or rubber strips)
3. Install threaded rod into drilled holes using concrete epoxy (Conair recommends Unitex Pro-
Poxy 300 Fast (A/B) with dual-pack and dual-cartridge gun for ease of use). Follow
manufacturer’s directions. Typical cure time before tightening is 24 hours.
4. Secure toe clamps with 3/4" washer and nut using spacer block underneath free end of clamp
at same thickness or less of material to be clamped. (Conair recommends McMaster-Carr
p/n: 4997A13 toe clamps)
5. Tighten fasteners to proper torque.

NOTE: Bolt torque chart located in the appendix.

19
3-4 Electrical installation
All electrical installation should conform to local, state and federal regulations and should be
performed by qualified personnel. All electrical wiring should be of sufficient size to ensure
adequate power supply without a power drop. The electrical control panel should be located as
close to the main drive motor as is feasible. This will ensure a minimum voltage drop. The control
panel should be installed in a well ventilated area protected from the elements, free of dust and the
direct rays of the sun.
Before applying power on a permanent basis check the following:
1. Direction of rotation of main motor
2. Direction of rotation of hydraulic pump motor
It is strongly recommended that power be applied to the machine only after pre-startup tests are
performed by service representatives.
3-5 General Installation Information
The machine should be located in an area that is protected from the elements. The machine is
normally delivered containing lubricants with minimum operating temperatures as follows:
Minimum Temperatures
Hydraulic System 20°F
Fluid Coupling 10°F
Bearings 0°F
Main motor 0°F
If special requirements exist below these temperatures, contact Conair Service (800-458-1960).
Optional heating element is available for the hydraulic system. The machine should be located in
an area that will provide adequate accessibility for maintenance.
Before starting machine rotate rotor slowly by hand to insure clearance between rotor, counter-
knife, cutters and screen. Check oil in gearbox and hydraulic reservoir. These units are filled with
specified fluid; refer to the maintenance section before adding any fluid to these units. Before
adding fluid insure that fluid and reservoir are clean.
Before operating machine, cycle the hydraulic pump several times for a short duration to insure
pump has fluid available. After establishing that hydraulic pump is providing pressure, cycle the
hydraulic cylinders without load several times to insure proper operation. Check Hydraulic
reservoir after each cycle. When hydraulic system is operating properly it should cycle through all
functions without hesitation.
Run machine approximately 30 minutes empty and then feed material slowly to the hopper until a
full load is established.
After two (2) hours of operation, then after every fifty (50) hours of operation check for loose bolts
and screws as well as belt tension. Tighten all loose bolts, screws and retighten belt if necessary.

Chapter 4: Machine Operation
4-1 General Operating Description
The machine is designed to reduce a variety of material to various chip sizes by the action of a rotor
containing specially designed cutters, passing through counter-knives, with the ultimate chip size
controlled by screen opening size. The process is summarized as follows.
The main drive motor, in conjunction with a fluid coupling/electronic soft start and a V-belt/direct
right-angle drive, transmits rotation to the gearbox. The gearbox in turn drives the rotor. The fluid
coupling/electronic soft start allows the motor to start while being under a load. The gearbox and
rotor are protected from sudden shock loads by a torque arm and over-torque limiting clutch.
Excessive overload is also limited by a sensor device on the clutch. The product is pushed to the
rotor by a hydraulically operated ram.
The functions of the machine are directed by an Allen Bradley Micro Logix 1500 programmable
logic controller (PLC), which receives input from a hydraulic pressure transducer, main drive
motor current, clutch sensors, safety interlock switch on rotor/screen door, a combined hydraulic
high temperature sensor and low fluid level, ram position sensors and external interlock. These
elements combine to cause the machine to operate or stop for personal safety or machine
protection.
The material feeding mechanism will push as much material as the rotor can size reduce. When the
rotor torque requirement causes the main drive motor load to reach programmable maximum
amperage, the feed mechanism stops or reverses and resumes pushing forward when the motor load
drops below programmed level.
The rotor is always turning in a forward direction during normal operation. The motor amperage is
being monitored using an analog input to the PLC. The amperage can reach either minor or major
faults.
Minor faults are reached when the rotor amperage is at or near full load amps. The full load
amperage is programmed using a percent (%) of load parameter. Actions on minor fault are
programmed for a ram hold or ram reversal. The ram reversal is either time based or until current
is under programmed limit. The ram hold is held until the amperage is under the programmed
limit.
Major faults are reached when the rotor significantly over amps the full load. This is normally set
at 140 – 150 % of load. Actions on major faults result in either a reversal procedure or an E-Stop.
The other major fault for the rotor is over torque. This would normally only happen from a sudden
shock stoppage such as tramp metal in the processing stream. This results in an e-stop to the
system. The machine should be inspected for damage and cause of the over torque before resuming
operation. The sensors and spring force of the over torque device should not be adjust in the field.

The ram force & hydraulic system pressure is being controlled by a pressure transducer on forward
strokes. This transducer is controlling the shift from high speed to low speed (on 2 speed machines
only), when to start and stop the ram and major and minor faults.
