SAFE WORKING
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 chipper 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. !

- to enter the machine, as damage is likely.
ALWAYS stop the tractor engine and disconnect
the PTO shaft before making any adjustments,
refuelling or cleaning.
ALWAYS check machine has stopped rotating
and remove tractor ignition key before
maintenance of any kind, or whenever the
machine is to be left unattended.
ALWAYS check machine is well supported and
cannot move.
ALWAYS run with the engine set to correct PTO
speed (1000 RPM).
ALWAYS check (visually) for fluid leaks.
ALWAYS take regular breaks. Wearing personal
protective equipment for long periods can be
tiring and hot.
ALWAYS keep hands, feet and clothing out of
feed opening, discharge and moving parts.
ALWAYS use the next piece of material or a push
stick to push in short pieces. Under no
circumstances should you reach into the funnel.
ALWAYS keep the operating area clear of people,
animals and children.
ALWAYS keep the operating area clear from
debris build up.
ALWAYS keep clear of the chip discharge tube.
Foreign objects may be ejected with great force.
ALWAYS ensure protective guarding is in place
before commencing work. Failure to do so may
result in personal injury or loss of life.
ALWAYS use chipper in a well ventilated area -
exhaust fumes are dangerous.

MOVING THE CHIPPER
DELIVERY
All Timberwolf PTO/300H 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 chipper. In
particular, read pages 5-8 which contains important health and safety information and advice.
OPERATOR’S PERSONAL PROTECTIVE EQUIPMENT REQUIRED
CHAINSAW safety helmet fitted with visor and
recommended ear defenders to an appropriate
specification.
HEAVY-DUTY gloves with elasticated wrist area.
CLOSE - FITTING heavy-duty non-snag clothing.
SAFETY footwear.
FACE MASK (if appropriate).
See page 5 for more detailed information.
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
CHECK the angle of the prop shaft when connected to the tractor, which should not exceed 16o.
CHECK that when the machine is lifted for transport the prop shaft does not reach an angle
that causes damage.
IF the prop shaft is supplied with a torque limiter or clutch, this must be fitted to the chipper
end of the drive shaft.
PTO SHAFT

OPERATING INSTRUCTIONS
DAILY CHECKS BEFORE STARTING TRACTOR
ENSURE drive shaft ends are securely fitted to PTO shaft and implement input shaft.
CHECK for properly guarded PTO shaft, implement input and drive shaft.
CHECK that guard chains are securely attached to stationary frame to prevent rotation of guard.
CONNECT power cable from tractor to chipper and turn on tractor side lights.
LOCATE the machine on firm level ground.
CHECK the discharge unit is in place and fastened securely.
CHECK discharge tube is pointing in a safe direction.
CHECK the feed funnel to ensure no objects are inside.
CHECK controls as described on page 10.
For parts location see diagrams on pages 3 & 4.
9
BEFORE USING THE CHIPPER
ENSURE feed funnel, feed roller guard, prop shaft guards and access covers are fitted and
secure, and that discharge unit is fitted and pointing in a safe direction.
WHEN ready to start chipping, increase PTO speed slowly until 1000 rpm is achieved.
IT IS ESSENTIAL TO CARRY OUT THE FOLLOWING TESTS to check safety equipment - this
sequence of tests will only take a few seconds to carry out. We recommend that these tests
are carried out daily. Observing the function as described will confirm that the safety circuits
are working correctly. This is also a good opportunity to remind all operators of the control and
emergency stop systems. After step 9 machine is ready to use.

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 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 and power lead connected with side lights on).
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.

Do not rely on the red bar to keep the rollers stationary if it is
necessary to clear or touch the rollers. Always remove power from the
chipper and disconnect PTO shaft before approaching the rollers.
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.
AUTO CONTROLS
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.
EMERGENCY STOPPING

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 rollers. 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.

OPERATING INSTRUCTIONS
PUSH the RED STOP button (see control panel diagram on 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 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.
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 while 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.
STOPPING THE CHIPPER
!!
12
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.

COPPER EASE SAFETY INFORMATION

SERVICE INSTRUCTIONS
ALWAYS stop the tractor engine before
installing or removing the prop shaft.
WHENEVER possible the pump belt
should be connected while changing
blades, as this will restrict sudden
movement of the rotor.
AVOID contact with hydraulic oil.
HANDLE blades with extreme caution to
avoid injury. Gloves should always be worn
when handling the cutter blades.
THE major components of this machine are
heavy. Lifting equipment must be used for
disassembly.
CLEAN machines are safer and easier to service.
SAFE MAINTENANCE
15
ALWAYS IMMOBILISE THE TRACTOR BEFORE UNDERTAKING ANY MAINTENANCE WORK ON THE CHIPPER.
Only fit genuine Timberwolf replacement blades, bolts and chipper spares. Failure to do so will result in the
invalidation of the warranty and may result in damage to the chipper, personal injury or even loss of life.
SPARES
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.
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 . 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.

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 across the machine
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 sharpening.
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 a blade to the rotor, the
underside of the blade, the tapered bolt
holes and the rotor must all be free of dirt
and debris.
10. Reassemble the blades, washers and bolts
in the order they were removed. Each pair
of Nordlock washers can be used a
maximum of 4 times - they are supplied
glued together to enhance correct assembly.
If separated, ensure the washer is fitted
together with the 2 ramp faces together
- NEVER with the faces mixed. For ease of
servicing we recommend replacing the M16
nuts at the same time as the Nordlock
washers are discarded. Apply a smear of
anti-seize compound to the bolt threads -
do not get copper grease on tapers in the
blade or on the bolt.
11. A calibrated torque wrench must be used
to tighten the bolts to a torque setting
of 125 lbs.ft (170 Nm).
12. 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).

SHARPEN THE ROLLER BLADES
x4
NOTE. If the roller blades become
worn and rounded to the point where
the in-feed pulling power of the
chipper becomes noticeably reduced,
it is permissible to sharpen the roller
blades by grinding in situ.
TENSION HYDRAULIC PUMP BELTS
NOTE: This is best done with the chipper removed from the tractor.

GREASING THE ROLLER BOX
Apply several pumps of grease to the four grease nipples, as
shown before each work session. DO NOT USE GRAPHITE
BASED GREASE.
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. For instructions on checking belt tension &
correct belt tension values, please refer to the Timberwolf V-Belt
Tensioning Data Table (pg 40).
3. Retighten the four pump plate bolts to 32lbs ft (50Nm).
NOTE: There will normally be a rapid drop in tension during run-in period for new belts. When new
belts are fitted, check the tension every 2 - 3 hours and adjust until the tension remains constant.
Belt failures due to lack of correct tensioning will not be covered under your Timberwolf warranty.

SERVICE INSTRUCTIONS 18
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.
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 16).
2. Undo and remove the anvil retaining screw using a 14mm Allen key.
3. Prise anvil away from the roller
box at screw end.
4. Withdraw from the locating
slot.
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.Refit the filter cup, install a new filter element and
refit the black screw cap to the filter housing,
ensuring o-ring remains in place.
