TIMBERWOLF TW PTO S426 SPECIFICATION
Power source Tractor PTO drive
Overall weight 1260kg
(without prop shaft)
Type of feed Hydraulic
Feed roller opening 426mm (17”) x 230mm (9")
Material processing capacity 3 tonnes/hr
Required engine power 80 - 115hp
PTO speed 1000rpm
The Timberwolf TW PTO S426
The Timberwolf PTO S426 is a high speed, heavy duty professional shredder. It is designed to shred general
green waste (brash, prunings, hedge trimmings, Leylandii, Christmas trees, rootballs, etc.),brushwood up to
100mm (4”) continuously, 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.
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 PTO S426 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.

5SAFE WORKING
BASIC SHREDDING SAFETY
he 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 PROTECTI E EQUIPMENT REQUIRED
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.
Face mask if
appropriate.
DO NOT
wear rings, bracelets, watches,
jewellery or any other items that
could be caught in the material
and draw you into the shredder.
Steel toe cap safety boots.

MANUAL CONTROLS
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.
GREEN BUTTON = Forward feed - Push the button once - this activates the roller and will allow you
to start shredding (if the drum speed is high enough).
B UE 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.

Ejection of material – Warning! The TW PTO S426 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.
WARNING IMITATIONS ON MATERIA S
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 drum housing. To clear a blockage proceed as follows:
STOP the tractor engine and remove the ignition
keys. Ensure drum has stopped turning by
observation of the drive shaft.
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.
WEARING 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 tractor, engage the PTO and run at
working speed. Allow sufficient time for the machine to
clear any residual material before recommencing work.
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 A TIMES.
Controlling the discharge is an essential part of safe working.

1. Turn off tractor and remove key.
2. Disconnect PTO shaft from the shredder.
3. Using a 24 mm spanner remove the two
M16 nuts clamping the drum housing shut.
4. Carefully lift the drum housing until it rests
on its stop.
5. Using the paddles to turn the drum, set a
bank of hammers at 12 o'clock.
6. With a 6mm hex key undo and remove
the bolt in the hammer at each end of the
bank of hammers.
7. The shaft can now be withdrawn. The
shaft will need to be tapped away from
the main drive pulley side.
8. As the shaft is removed the hammers will be
released off the shaft. These need to be
held and removed as the shaft is withdrawn.
9. The hammer replacement is the reverse of
the above with the addition of some copper
slip on the hammer retainer bolts. Note the
hammer bushes should not be greased or
lubricated in any way. Any build up of debris
should be removed from both the shaft and
the hammer bushes so the hammer can
swing freely.
10. Turn the drum to change the second bank of
hammers.
11. Lower the top of the drum housing and
reinstall the two M16 nuts.
12. Torque these to 65lbft.

All the hydraulic hoses should be regularly inspected for chafing and leaks. The hydraulic system is
pressurized to over 200 Bar 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 con-
stantly moving. If any hydraulic components are changed new seals should be installed during re-
assembly. Fittings should then be retightened correctly.

WARNING Wear heavy gloves for the blade changing operation.
