WARNING - LIMITATIONS ON MATERIALS.
To properly control the speed of material entering the shredder chamber, the machine
relies on the large feed roller to grip the material. The feed roller can grip material down to 15mm in diameter.
The machine will not tolerate or process items such as tyres, mattresses, heavy duty plastic containers (used
for oils, chemicals, etc.), carpets, reinforced concrete, metallic items exceeding lightweight domestic door
furniture, commercial plastic gas pipe, alkathene water pipe, metal reinforced drainage/irrigation pipe, baler
twine, rope, metal banding, computer hard drives (which contain magnets) and any similar objects to the
above.
Ejection of material – Warning! The S426TDHB shredder ejects material at high speed. Ensure there is an
adequate safety zone and that ejected material is aimed away from operators into a safe area, i.e. an
enclosure or container with a back stop (i.e. wall) behind it to prevent ejected material from leaving the work
area and causing injury and damage. If loading into a truck or trailer, ensure the structure is strong enough to
cope with the impact from ejected material.

BASIC SHREDDING SAFETY
The operator should be aware of the following points:
MAINTAIN A SAFETY EXCLUSION ZONE around the shredder of at least 10 metres for the
general public or employees without adequate protection. Due to the nature of material being
shredded and the distance/velocity of discharge, the exclusion zone must be extended to 20
metres in front of the discharge tube exit. Use hazard tape to identify this working area and
keep it clear from debris build up. Shredded material should be ejected away from any area the
general public have access to.
HAZARDOUS MATERIAL - Some species of trees and bushes are poisonous. The shredding
action can produce vapour, spray and dust that can irritate the skin. This may lead to
respiratory problems or even cause serious poisoning. Check the material to be shredded
before you start. Avoid confined spaces and use a facemask if necessary.
BE AWARE when the shredder is processing material that is an awkward shape. The material
can move from side to side in the funnel with great force. If the material extends beyond the
funnel, the brash may push you to one side causing danger.
BE AWARE that the shredder can eject material out of the feed funnel with considerable force.
Always wear full head and face protection.
ALWAYS work on the side of the machine furthest from any local danger, e.g. not road side.
WARNING
The shredder will feed material through on its own. To do this, it relies on
the hammers to be free to swing. DO NOT put bricks, large stones, string,
carpet, tyres or metal into the shredder. !
!
OPERATOR'S PERSONAL PROTECTIVE EQUIPMENT REQUIRED
Chainsaw safety helmet
fitted with mesh visor and
recommended ear defenders
to the appropriate
specifications.

Control Box Diagram
Roller control boxes- two control boxes are located on either side of the feed tray. Their function is
to control the feed roller that draw material into the machine. They do not control the main rotor.
RED SAFETY BAR = This is the large red bar that surrounds the feed tray and side of the feed funnel.
The bar is spring loaded and connected to a switch that will interrupt the power to the roller. The
switch is designed so that it only activates if the bar is pushed to the limit of its travel. The roller will
stop instantly, but can be made to turn again by pressing either the GREEN FEED or BLUE
REVERSE control buttons.
GREEN BUTTON = Forward feed - Push the button once - this activates the roller and will allow you
to start shredding (if the rotor speed is high enough).
BLUE BUTTON = Reverse feed - allows you to back material out of the roller. The roller will only turn
in reverse as long as you keep pressing the button.
See page 5 for more detailed information.
Do not rely on the red bar to keep the roller
stationary if it is necessary to clear or touch the
roller. Always switch off the machine and remove
ignition key before approaching the roller.
There are two control boxes, located on
either side of the feed tray.

SHREDDING
WARNING
Limitations on materials.
To properly control the speed of material entering the shredder chamber, the machine relies on the large feed
roller to grip the material. The feed roller can grip material down to 15mm in diameter. The machine will not
tolerate or process items such as tyres, mattresses, heavy duty plastic containers (used for oils, chemicals,
etc.), carpets, reinforced concrete, metallic items exceeding lightweight domestic door furniture, commercial
plastic gas pipe, alkathene water pipe, metal reinforced drainage/irrigation pipe, baler twine, rope, metal
banding, computer hard drives (which contain magnets) and any similar objects to the above.
Ejection of material – Warning! The S426TDHB shredder ejects material at high speed. Ensure there is an
adequate safety zone and that ejected material is aimed away from operators into a safe area, i.e. an enclosure
or container with a back stop (i.e. wall) behind it to prevent ejected material from leaving the work area and
causing injury and damage. If loading into a truck or trailer, ensure the structure is strong enough to cope with
the impact from ejected material.
!!
BLOCKAGES
Always be aware that what you are putting into the shredder must come out. If the material stops coming out
of the discharge tube but the shredder is taking material in - STOP IMMEDIATELY. Continuing to feed material
into a blocked machine may cause damage and will make it difficult to clear. Two areas of the machine can
become blocked - the discharge tube and the rotor housing. To clear a blockage proceed as follows:
Continuing to feed the shredder with material once it has become blocked will cause the shredder to
compact material in the rotor housing and discharge chute and it will be difficult and time consuming
to clear.
AVOID THIS SITUATION - WATCH THE DISCHARGE TUBE AT ALL TIMES.
STOP the engine and remove the keys.
REMOVE the two rotor housing securing nuts and open the rotor housing until it rests against the
rubber stop. WARNING! Ensure the weight of the discharge tube is fully supported whilst opening
the rotor housing, to avoid injury and damage.
REMOVE any blockage from the discharge tube, ensuring that it is clear along its entire length.
WEARING gloves, reach into the rotor housing and remove the material causing the blockage,
including any material that may have also entered the side fan casing. WARNING! Beware of turning
the rotor whilst clearing a blockage, as this could lead to injury.
CLOSE the rotor housing and replace and tighten the two securing nuts. WARNING! Ensure the
weight of the discharge tube is fully supported whilst lowering the rotor housing, to avoid injury and
damage.
RESTART the engine and increase to full throttle. Allow sufficient time for the machine to clear any
residual material before recommencing work.

1. Storage and transport
- Batteries are filled with acid.
- Always store and transport batteries upright
and prevent from tilting so that no acid can
escape.
- Store in a cool and dry place.
- Do not remove the protective cap from the
positive terminal.
- Run a FIFO (first in-first out)warehouse
management system.
2. Initial operation
- The batteries are filled with acid at a density of
1.28g/ml during the manufacturing process and
are ready for use.
- Recharge in case of insufficient starting power
(cf. section 4).
3. Installation in the vehicle and removal from
the vehicle
- Switch off the engine and all electrical
equipment.
- When removing, disconnect the negative
terminal first.
- Avoid short circuits caused by tools, for example.
- Remove any foreign body from the battery tray,
and clamp battery tightly after installation.
- Clean the terminals and clamps, and lubricate
slightly with battery grease.
- When installing, first connect the positive
terminal, and check the terminal clamps for
tight fit.
- After having fitted the battery in the vehicle,
remove the protective cap from the positive
terminal, and place it on the terminal of the
replaced battery in order to prevent short
circuits and possible sparks.
- Use parts from the replaced battery, such as
the terminal covers, elbows, vent pipe
connection and terminal holders (where
applicable); use available or supplied filler caps.
- Leave at least one vent open, otherwise there
is a danger of explosion. This also applies
when old batteries are returned.
4. Charging
- Remove the battery from the vehicle;
disconnect the lead of the negative terminal first.
- Ensure good ventilation.
- Use suitable direct current chargers only.
- Connect the positive terminal of the battery to
the positive output of the charger. Connect the
negative terminal accordingly.
- Switch on the charger only after the battery has
been connected, and switch off the charger first
after charging has been completed.
- Charging current-recommendation: 1/10
ampere of the battery capacity Ah.
- Use a charger with a constant charging voltage
of 14.4V for re-charging.
- If the acid temperature rises above 55o Celsuis,
stop charging.
- The battery is fully charged when the charging
voltage has stopped rising for two hours.
5. Maintenance
- Keep the battery clean and dry.
- Use a moist anti-static cloth only to wipe the
battery, otherwise there is a danger of
explosion.
- Do not open the battery.
- Recharge in case of insufficient starting power
(cf. section 4).
6. Jump Starting
- Use the standardised jumper cable in
compliance with DIN 72553 only, and follow the
operating instructions.
- Use batteries of the same nominal voltage only.
- Switch off the engines of both vehicles.
- First connect the two positive terminals (1) and
(2), then connect the
negative terminal of the
charged battery (3) to a
metal part (4) of the
vehicle requiring
assistance away from the battery.
- Start the engine of the vehicle providing
assistance, then start the engine of the vehicle
requiring assistance for a maximum of 15
seconds.
- Disconnect the cables in reverse sequence
(4-3-2-1).
7. Taking the battery out of service
- Charge the battery; store in a cool place or in
the vehicle with the negative terminal
disconnected.
- Check the battery state of charge at regular
intervals, and correct by recharging when
necessary (cf. section 4).

The TW S426TDHB is subject to large vibrations during the normal course of operation.
Consequently there is always a possibility that nuts and bolts will work themselves loose. It is
important that periodic checks are made to ensure the security of all fasteners. Fasteners should be
tightened using a torque wrench to the settings listed below . Uncalibrated torque wrenches can be
inaccurate by as much as 25%. It is therefore essential that a calibrated torque wrench is used
to achieve the tightening torques listed below.

CHECK HOSES
All the hydraulic hoses should be regularly inspected for chafing and leaks. The hydraulic system is
pressurized to 150 Bar (2175 PSI) and thus the equipment containing it must be kept in good condition.
Identify the hoses that run to the top motor. These have the highest chance of damage as they are
constantly moving. If any hydraulic components are changed new seals should be installed during
reassembly. Fittings should then be retightened.
