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.

OPERATING INSTRUCTIONS
BEFORE STARTING TRACTOR
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.
DO NOT move the chipper with the rotor running.
ALWAYS ensure the discharge transport pin is in place before moving.
MOVING THE CHIPPER
CONNECTING TO TRACTOR

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 feed table and side 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 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.
RED SAFETY BAR TEST.
To ensure the safety bar is always operational it must be activated once before each work session.
The rollers will not function until the bar is activated. This procedure must be repeated each time
the ignition is switched off.
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, twist until it returns 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.
MANUAL CONTROLS
AUTO 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
either forward or reverse until the rotor speed rises above the predetermined level, at which point the
feed rollers will start turning without warning.
Do not rely on the red bar to keep the rollers stationary if it
is necessary to clear or touch the rollers. Always switch off
the machine before approaching the rollers.

DISCHARGE CONTROLS
As the wood is chipped the chips will exit the machine via the discharge tube. The discharge tube
may be adjusted so that the chips fall in a convenient and safe place. Small adjustments are possible
with little effort.
To aid the adjustment of the discharge tube a 3 in 1 tool is provided. It is designed to do all the
adjustments required using the correct amount of force. It is attached to the discharge flange on a
length of cord.
ITS THREE FUNCTIONS ARE (FIG 5);
i) A transport pin ii) Clamping the bucket adjustment iii) Adjusting the turning friction
i
iii
ii
THE DISCHARGE CONTROLS ARE (FIGS 5&6);
1. Transport position 2. Bucket Attitude 3. Tube rotation 4. Friction setting
TRANSPORT POSITION - As the discharge tube is used without a rotational clamp it is necessary
to fix its position when being transported.
WARNING
Failure to secure the discharge during transport can result in serious damage to
the machine and its surroundings.
With the discharge pointing in the direction shown two holes line up and the tool may be dropped into
position (fig. 5, i).
BUCKET ATTITUDE - Using the tool the 19mm nut may be loosened and the control handle moved
to a suitable position (fig. 5, ii).
TUBE ROTATION -
- Remove the tool from the transport position (fig. 5, i).
- Unclip the tubular turning handle from underneath the discharge tube (fig. 6).
- Push or pull the turning handle to a suitable position.
- Clip the turning handle back into position.
FRICTION SETTING - Whilst rotating the discharge tube it may be found that the effort required is
either too much or too little. Too little effort and the discharge tube may rotate without warning. Too
much effort and small adjustments will be difficult. A 17mm screw underneath the discharge flange
can be wound in or out to adjust the friction overall. This can be adjusted to suit the operator or
working environment (fig. 5, iii).
fig 5. fig 6.

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 and set revs to 1500 rpm.
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.
RELEASE the catch on the feed table and lower. Turn to release 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.
12
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 7.

OPERATING INSTRUCTIONS
PUSH the RED STOP button (see Control Panel fig. 4, page 10).
SHUT feed funnel.
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.

SERVICE INSTRUCTIONS
ALWAYS IMMOBILISE THE TRACTOR BEFORE UNDERTAKING ANY MAINTENANCE
WORK ON THE CHIPPER.
ALWAYS stop the tractor engine before installing or removing the prop shaft.
HANDLE blades with extreme caution to avoid injury. Gloves should always be worn when
handling the cutter blades.
AVOID contact with hydraulic oil.
WHENEVER possible the pump belt should be connected while changing blades, as this
will restrict sudden movement of the rotor.
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
Only fit genuine Entec 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
GREASE THE ROLLER BOX SLIDES
NOTE: This should be done regularly. In dirty or dusty conditions or during periods of hard
work it should be done daily. If the slides become dry the top roller will tend to hang up and
the pulling-in power of the rollers will be much reduced. Excessive wear will ensue.
1. Remove the top roller box cover.
2. Apply thin grease with a brush to each slide.
3. Refit the cover.
fig 12.

GREASING THE ROLLER BOX
Apply several pumps of grease to the three grease nipples shown
before each work session. If your chipper has not been fitted with
this system, follow the instructions for Grease the Roller Box Slides
and Grease the Roller Drive Splines.
fig 11.

SERVICE INSTRUCTIONS
1. Rotate Discharge Chute fully anticlockwise and
clamp.
2. Locate Rotor Housing bolts.
3. Using 2 x 24mm spanners remove the bolts.
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).
WARNING
Wear riggers gloves for the blade changing operation.

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 black knob at the bottom of the pump plate until the
desired tension is achieved. Tension is correct when 4.5kg of force
deflects one belt 16mm 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).
GREASE THE ROLLER DRIVE SPLINES
NOTE: This should be done four times a year or every 50 hours. If the grease in the splines
is allowed to dry out, rapid wear of the roller splines will occur resulting in a breakdown and
the need to fit replacement parts. This failure is not warranty.
1. Remove the top guard and open side guard.
2. Locate two grease nipples; one in the centre of each roller shaft.
3. Use a pump action grease gun to apply a generous amount of
grease to each roller drive.
4. Refit the covers.
fig 18.
fig 17.
The Timberwolf 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 .
