SAFE WORKING
OPERATOR'S PERSONAL PROTECTIVE EQUIPMENT REQUIRED
Chainsaw safety helmet fitted
with visor and recommended
ear defenders to the
appropriate specifications
Loose fit,
Heavy-duty gloves.
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 chipper.
BASIC WOODCHIPPING SAFETY
The operator should be aware of the following points:
MAINTAIN A SAFETY EXCLUSION ZONE around the chipper of at least 10 metres for the
general public or employees without adequate protection. - Use hazard tape to identify this
working area and keep it clear from debris build up. Chips should be ejected away from any
area the general public have access to.
HAZARDOUS MATERIAL - Some species of trees and bushes are poisonous. The chipping
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 chipped before
you start. Avoid confined spaces and use a facemask if necessary.
BE AWARE when the chipper 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. Badly twisted brash should be
trimmed before being chipped to avoid thrashing in the feed funnel.
BE AWARE that the chipper can eject chips 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 Timberwolf PTO will feed material through on its own. To do this, it relies on
sharp blades on the chipper rotor. To keep the blades sharp, only feed
the machine with clean brushwood.
DO NOT put muddy / dirty wood, roots, potted plants, bricks,
stones or metal into the chipper.

HEAVY-DUTY gloves.
CLOSE - FITTING heavy-duty non-snag clothing.
SAFETY footwear.
FACE MASK (if appropriate).
See page 5 for more detailed information.

OPERATING INSTRUCTIONS
Roller control box - is the control box above the feed opening of the chipper funnel. Its function is to control
the feed rollers. The feed rollers draw material into the machine. It does not control the main rotor.
RED SAFETY BAR = This is the large red bar that surrounds the top and sides of the feed funnel.
The bar is spring loaded and connected to a switch that will interrupt the power to the rollers. The
switch is designed so that it only activates if the bar is pushed or pulled to the limit of its travel. The
rollers stop instantly, but can be made to turn again by pressing either the GREEN FEED or BLUE
REVERSE control buttons.
LOW STOP BAR = An additional stop bar is located along the bottom of the low funnel. This is linked
directly to the main bar, and will stop the rollers if pushed only. Pulling this bar will only move it into
its ‘stowed’ (up) position.
GREEN BUTTON = forward feed - Push the button once - this activates the rollers and will allow you
to start chipping (if the rotor speed is high enough).
RED BUTTON = stop feed / emergency stop - This button stops the rollers from feeding. It overrides
all other buttons or bars and will not allow the other buttons to function until it has been reset.
To reset, pull out to its original position. The forward and reverse buttons will now function.
BLUE BUTTON = reverse feed - allows you to back material out of the rollers. The rollers will only
turn in reverse as long as you keep pressing the button. You do not have to press the STOP button
before pressing the GREEN FEED button to recommence feeding. NOTE: This reverse function will
work even if the safety bar is pushed or pulled.
MANUAL CONTROLS
The no stress unit controls the feed rate of the material going into the chipping chamber. If the rotor
speed is below the predetermined level the No Stress Unit will not allow the feed rollers to work in the
forward direction until the rotor speed rises above the predetermined level, at which point the feed
rollers will start turning automatically without warning. NOTE: The reverse button will operate at any
speed, and with the safety bar pressed or pulled.
Control Panel Diagram
Push the RED STOP button or push the RED SAFETY BAR
(whichever is the quickest for you to reach).
Turn off tractor ignition key or operate tractor stop lever.
The emergency stop will prevent any more material being fed into the chipper. The rotor will still be
turning. The tractor must be disengaged or powered down to stop the rotor.

AUTO CONTROLS

OPERATING INSTRUCTIONS
CHIPPING
Wood up to 300mm diameter can be fed into the feed funnel. Put the butt end in first and engage it
with the feed roller. The hydraulic feed rollers will pull the branch into the machine quite quickly. Large
diameter material will have its feed rate automatically controlled depending on the tractor power
available.
Sometimes a piece of wood that is a particularly awkward shape is too strong for the feed rollers to
break. This will cause the top roller to either bounce up and down on the wood or both rollers to stall.
If this occurs press the BLUE REVERSE button until the material has been released. Pull the material
out of the feed funnel and trim it so the chipper can handle it.
Both feed rollers should always turn at the same speed. If one or both rollers stop or suddenly slow
down it may be that a piece of wood has become stuck behind one of the rollers. If this occurs press
the BLUE REVERSE button and hold for 2 seconds - then repress GREEN FEED button. This should
enable the rollers to free the offending piece of material and continue rotating at the correct speed. If
the rollers continue to stall in the 'forward feed' or 'reverse feed' position push the RED STOP
BUTTON, turn tractor engine off, remove ignition key and investigate.
STARTING THE CHIPPER
WARNING
Do not use or attempt to start the chipper without the
protective guarding and discharge unit securely in place.
Failure to do so may result in personal injury or loss of life.
!!
CONNECT the tractor power cable.
START tractor.
GENTLY engage PTO clutch.
INCREASE tractor revs until tractor PTO speed = 1000 rpm.
DO NOT RUN ON ANY OTHER PTO SPEED SETTING.
CHECK that chipper is running smoothly.
PULL the red stop button.
PRESS the green control button. The rollers will commence turning.
STAND to one side of the feed funnel.
PROCEED to feed material into the feed funnel.
11
This is situated on the side of the hydraulic oil tank. When the chipper is
running the oil temperature should not exceed 65oC. If it does, stop the
machine immediately. Failure to do so may result in damage. Overheating can
result from the chipper being worked extremely hard in hot conditions, as the
oil is not getting a chance to cool down. Stop the chipper and allow oil to cool
before continuing. If the temperature goes above 65oC and the machine is not
being worked hard or the air temperature is not particularly high this indicates low
oil, a jammed hydraulic motor or valve. Stop immediately and investigate.
When the chipper is on level ground the oil level should sit between the red
line at the bottom of the gauge and the blue line at the top. If this level drops
significantly it indicates an oil leak. Stop immediately and investigate.
HYDRAULIC OIL THERMOMETER / OIL LEVEL INDICATOR
fig 6.

OPERATING INSTRUCTIONS
PUSH the RED STOP button (see Control Panel fig. 5, page 10).
KEEPING PTO engaged set tractor speed to idle.
WHEN idle speed steady stop tractor engine.
WHEN engine stationary disengage PTO clutch.
DO NOT disengage the PTO clutch while engine is running as the chipper cutting disc may
continue to free wheel for a long time.
BLOCKAGES
Always be aware that what you are putting into the chipper must come out. If the chips stop coming
out of the discharge tube but the chipper is taking material in - STOP IMMEDIATELY. Continuing to
feed material into a blocked machine may cause damage and will make it difficult to clear.
If the chipper becomes blocked proceed as follows:
STOP the tractor engine and remove the ignition keys. Ensure rotor has stopped turning by
observation of the drive shaft.
REMOVE the two opening rotor housing bolts and use the handle to raise the housing.
The chips causing the blockage should fall clear. It is not necessary to remove all the chips.
Some will remain lying in the bottom of the rotor housing, which the chipper will eject when it
is restarted.
WARNING
Do not reach into the rotor housing with unprotected hands. There are
sharp blades and any small movement of the rotor may cause serious injury.
CLOSE the housing and re install the bolts.
RESTART tractor, engage the PTO and run at working speed.
ALLOW machine time to clear excess chips still remaining in rotor housing before you
continue feeding brushwood. Feed in a small piece of wood whilst watching to make sure
that it comes out of the discharge. If this does not clear it, repeat the process and carefully
inspect the discharge tube to find any obstruction.
NOTE
Continuing to feed the chipper with brushwood once it has become blocked will cause the chipper to
compact the chips in the rotor housing and it will be difficult and time consuming to clear.
AVOID THIS SITUATION - WATCH THE DISCHARGE TUBE AT ALL TIMES.

SAFE LIFTING OF THE PT0 300
The TW PTO 300 wood chipper has been designed to be lifted
safely utilising two lifting positions together. The main lifting eye
located at the top of the narrow end of the feed funnel, and the
uppermost of the three-point tractor mounts must only be used
together.
A chain or strap, which is 700mm long (1) and having a rating of 1.5
tons, is to be attached with a suitable shackle to the lifting eye. A
second chain or strap, 1200mm long, (2) also rated at 1.5 tons
minimum, is to be attached to the second lifting point (the uppermost
of the three-point tractor mount with its pin.) Both of these lifting
apparatus are to be attached together to the appropriate lifting
equipment via a hoist hook.

SERVICE INSTRUCTIONS
1. Rotate discharge chute fully anticlockwise
and clamp.
2. Locate rotor housing bolts.
3. Using a 24mm spanner remove the bolt plate.
4. Lift the rotor housing until the catch engages.
5. Turn the rotor to a convenient position using
the fan blades. Use a large piece of wood (at
least 600mm) to wedge the rotor and prevent
it from turning.
6. Brush away all dirt and debris from the rotor
and blades.
7. Using a 24mm socket spanner remove the
two M16 nuts at the back of one blade,
blades are reversible and can be turned to
allow use of the opposite side. If both sides
are blunt or damaged the blade should be
removed for re-grinding.
8. After removing the blade from the rotor it is
necessary to extract the bolts from it. To
do this lay the blade face down on a solid
metal surface and give the thread end of
each bolt a sharp tap with a hammer. The
bolt is specially machined to allow for this.
9. Before refitting the blade in the rotor, the
underside of the blade and the tapered
bolt holes must all be scrupulously
clean.
10. Refit the blades when ready to do so.
Apply a smear of anti seize compound to the
bolt threads and tighten the M16 nuts to
150 Lbft / 203Nm.
11. Release the catch and lower the rotor
housing into place. It will be necessary to
push it down the last bit to overcome the
assister spring. Fit the two retaining bolts
and tighten to 65 lbs ft (88Nm).

SERVICE INSTRUCTIONS
TENSION HYDRAULIC PUMP BELT
NOTE: This is best done with the chipper removed from the tractor.
1. Access four screws (two either side) that support the pump mounting
plate and slacken using a 17mm socket spanner. The nuts are captive.
2. Adjust the bolt at the bottom of the pump plate until the desired
tension is achieved. Tension is correct when 3kg of force deflects one
belt 4mm at the centre of its span. (Push the belt firmly with your
index finger; it should deflect to roughly the depth of your fingernail).
3. Retighten the four pump plate bolts to 40 lbs ft (55Nm).
fig 13.
The Timberwolf PTO 300H 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 .

SERVICE INSTRUCTIONS
WARNING
This job is best carried out when changing the blades. Before attempting to
change the anvil follow the instruction for changing the blades
and remove all the blades.
The anvil is made of toughened wear resistant steel, but eventually wear will occur on the top edge.
When this happens the chipper will not cut stringy thin material as efficiently. If this becomes a problem
the anvil should be replaced.
CHANGE ANVIL
4. Withdraw from the locating slot.
5. Before fitting a new anvil reach in and
carefully clean the anvil seat.
6. Refitting is an exact reversal of the removal process.
1. Remove blades (see page 17).
2. Undo and remove the anvil retaining screw
using a 14mm Allen key.
3. Prise anvil away from the rollerbox at screw end.
fig 16.
WARNING
Use plastic gloves to keep oil off skin and dispose of the used oil and filter in an
ecologically sound way. The oil and filter should be changed once a year or at
any time it becomes contaminated. Before starting check that the chipper is
standing level and brush away loose chips.
CHANGE HYDRAULIC OIL AND FILTER
1. Remove the black screw cap from the top of the filter
housing.
2. Partially remove filter element from inner cup. Leave filter
to drain for 15 minutes.
3. Remove filter element from cup when clear of hydraulic oil.
4. Remove drain plug and drain oil into a suitable container.
5. Replace drain plug.
6. Refill with VG 32 hydraulic oil until the level is half way up
the sight glass (about 40 litres).
7. Replace the filter cup, install a new filter element and
replace the filter cap (screw).
fig 14.
CHECK HOSES
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
constantly moving. If any hydraulic components are changed new seals should be installed during
reassembly. Fittings should then be retightened correctly.
