The Timberwolf TW S426TDHB
The Timberwolf S426TDHB is a high speed, heavy duty professional shredder. t is designed to shred general
green waste (brash, prunings, hedge trimmings, Leylandii, Christmas trees, rootballs, etc.),brushwood up to
100mm (4”), pallets, domestic doors, wooden and plastic window frames (all pre-cut to fit feed aperture),
contaminated timber, chipboard, MDF, packaging materials, uPVC plastic, cardboard, wooden furniture, fence
posts and similar items. The machine will tolerate drinks cans, plastic bottles, stones, rocks and concrete (up
to fist size), nails, metal door furniture, glass bottles and similar items.
TIMBERWOLF
TW S426TDHB
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.
NOTE: When materials are corrosive they may attack and degrade the individual components. It is essential that
the unit be thoroughly cleaned down after shredding anything that may contain materials of an aggressive nature.
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. f loading into a truck or trailer, ensure the structure is strong enough to
cope with the impact from ejected material.

TIMBERWOLF
TW S426TDHB

The TW S426TDHBA shredder has the ability to adjust the towhead height to correspond with the
vehicles towing point.
The preferred towing angle of any shredder is with the
chassis level to the ground. The adjustable head has
the ability to move between 300mm from the ground
to 875mm giving an overall adjustment of 575mm.
The towhead latch and handbrake fundamentally
work the same as a fixed standard towhead, however
the front section of the head is retained in position via
a locking ring and single clamp handle.
To adjust the height the locking handle located on the
side of the head (1) is turned in an anticlockwise
direction to allow for the locking ring to disengage
from its apposing ring. An internal damper is fitter to
support the heads weight allowing both hands free to
adjust the height. Once the desired height has been
achieved the locking handle is turned clockwise until
tight. The latching of the hitch is as normal as is the fitting of the light plug and breakaway cable as
outlined in the ‘Hitching onto the tow ball’ section on page 9.

BASIC SHREDDING SAFETY
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 E UIPMENT RE UIRED
Chainsaw safety helmet fitted
with mesh visor and
recommended ear defenders to
the appropriate specifications.
Work gloves with elasticated
wrist.
Close fitting heavy-duty
non-snag clothing.

TIMBERWOLF
TW S426TDHB
he operator should be aware of the following points:
MA NTA N A SAFETY EXCLUS ON 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 MATER AL - 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. f 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.

ü

DELIVERY
OPERATOR’S PERSONAL PROTECTIVE E UIPMENT RE UIRED
MANUAL CONTROLS
All Timberwolf 426TDHB & 426TDHBA machines have a full pre - delivery inspection before
leaving the factory and are ready to use. Read and understand this instruction manual before
attempting to operate the shredder. In particular, read pages 6-8 which contain important health and
safety information and advice.
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. hey do not control the main drum.
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.
WARNING DO NOT remove, jam, disable, bypass, override or otherwise
impede the effectiveness of the red safety bar.

OPERATING INSTRUCTIONS

HYDRAULIC OIL LEVEL INDICATOR
Always be aware that what you are putting into the shredder must come out. f the material stops coming out of
the discharge tube but the shredder is taking material in - STOP MMED ATELY. 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 drum 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 drum 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 drum housing securing nuts and open the drum housing until it rests against the
rubber stop. WARNING! Ensure the weight of the discharge tube is fully supported whilst opening
the drum housing, to avoid injury and damage.
REMOVE any blockage from the discharge tube, ensuring that it is clear along its entire length.
WEAR NG gloves, reach into the drum 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 drum whilst clearing a blockage, as this could lead to injury.
CLOSE the drum housing and replace and tighten the two securing nuts. WARNING! Ensure the
weight of the discharge tube is fully supported whilst lowering the drum 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.
This can be viewed through the wall of the tank. Maximum and minimum marks are provided.
The fuel level can be seen through the tube fitted to the side of the tank.
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.
NOTE: When materials are corrosive they may attack and degrade the individual components. It is essential that the
unit be thoroughly cleaned down after shredding anything that may contain materials of an aggressive nature.
Ejection of material – Warning! The TW S426TDHB / TW S426TDHBA 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. f loading into a truck or trailer, ensure the structure is strong enough
