BA IC WOODCHIPPING AFETY
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.
AZARDOUS 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
AFE WORKING
The chipper will feed material through on its own. To do this, it relies on sharp
blades both on the feed rollers and 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.
OPERATOR' PER ONAL PROTECTIVE 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 chipper.
Steel toe cap safety boots.

RED STOP FEED -
EMERGENCY STOP BUTTON
RED SAFETY BAR
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 sides and top of the feed funnel (sides
and bottom on high 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 (pushed or
pulled...low funnel only) 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 SAFETY BAR = An additional safety 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 = 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. Pull the button out to
reset, 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 switch off the
machine and remove ignition key before approaching the rollers.
Control Panel Diagram

TIMBERWOLF
TW 150VTR/FTR
9OPERATING IN TRUCTION
The chipper is designed to operate in either chipper or crawler mode, but not both at the same time.
C IPPING MODE
Power is available to the feed rollers. The cutting disc is rotating but the unit is stationary.
CRAWLER TRACK MODE
Power is available to the crawler tracks. The cutting disc is rotating but the feed rollers are stationary.
To switch between modes, a lever is operated (see diagram below). This is located on the driving
control panel (see parts locator on page 3). It is clearly marked.
When Track mode is selected the two track control valves may be operated. These have direct
control over the track relevant to each side of the machine. They are proportional valves, so increased
movement will result in increased track speed.
Tracking may be done at either high or low engine speed. Manoeuvring the
machine in tight spaces and while loading and unloading should be done with
the engine on low speed.
There are three ways of stopping the TW 150VTR/FTR chipper in the event of an emergency.
STOPPING T E ROLLERS
-Activating the red safety bar will stop the rollers immediately. To restart the rollers, just push the green
forward button or blue reverse button.
-Pushing the red Emergency button on the roller control box will also stop the rollers immediately. The
button will stay in the “pushed in” position, and will require resetting (pulling out) before being able to
restart the roller functions.
STOPPING T E ENGINE
Should the entire machine need to be stopped in an emergency, the red button on top of the engine
guard should be pushed. This will shut down the engine in the shortest possible time. The engine
cannot be restarted until the button is pulled out and the main ignition switch is turned off to reset the
machine.
NOTE: Ensure low safety bar on
low funnel is rotated into the ‘stowed’
(up) position prior to tracking to
avoid damage to the bar.
WARNING NEVER LEAVE THE CHIPPER ON A SLOPE UNATTENDED.
Tracks
out
Tracks
in
For machines fitted with variable
tracks, track width adjustment is only possible with the
track/chip control in the chip position. Track adjust handle is
spring loaded to the middle (see diagram, right). The more you
move the handle, the more the tracks adjust. To move the tracks outward, move the
track adjust handle up. To bring tracks inward, move the track adjust handle down.
CRAWLER TRACK CONTROL
The engine management unit controls the feed rate of the material going into the chipping chamber. If the
engine speed is below the predetermined level, the engine management unit will not allow the feed rollers
to work in the forward feed direction, until the rotor speed rises above the predetermined level. At this
point the feed rollers will start turning without warning. The reverse function will work at any speed.

CHIPPING
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.
Wood up to the recommended 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 by the no stress unit.
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 the engine off, remove the ignition key and investigate.

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.

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
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.
If the chipper becomes blocked, proceed as follows:
STOP the engine and remove the ignition keys.
REMOVE the discharge tube. Check that it is clear.
WEARING gloves, reach into the rotor housing and scoop out the majority of the debris
causing the blockage.
TIMBERWOLF

REPLACE the discharge tube.
RESTART the engine and increase to full 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.
BLOCKAGE
OPERATING IN TRUCTION
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.
1. DISCONNECT the control box loom from the engine loom at the
connection point location under the near side of the funnel.
2a. ON the high funnel / tray, ensure tray is closed and catches are latched.
2b. ON the low funnel, rotate low safety bar into its ‘stowed’ (up) position.
3. RELEASE the two catches that secure the funnel to the chassis,
located underneath funnel. (Only one catch on high funnel).
4. WIT two people in position, lift the funnel by the handles (if fitted),
ensure the wide end is lifted first then release the narrow end from the roller box assembly.

BLADE WEAR
The most important part of using a wood chipper is keeping the cutter blades sharp. Timberwolf
chipper blades are hollow ground to an angle of 40 degrees. When performing daily blade checks
ensure blade edge is sharp and free from chips, if there is any evidence of damage, or the edge is “dull”
change the blade(s). The TW 150VTR/FTR is fitted with 2 blades 101mm (4") long. They are 44 mm
wide when new. A new blade should chip for up to 25 hours before it requires sharpening. This figure
will be drastically reduced by feeding the machine with stony, sandy or muddy material.
As the blade becomes blunt, performance is reduced. With increased stress and load on the machine
the chips will become more irregular and stringy. At this point the blade should be sent to a reputable
blade sharpening company. The blade can be sharpened several times in its life. A wear mark on the
reverse side indicates the safe limit of blade wear. Replace when this line is exceeded.
The machine is also fitted with a static blade (anvil). It is important that the anvil is in good condition
to allow the cutting blades to function efficiently. Performance will be poor, even with sharp cutter
blades, if the anvil is worn.

1. Storage and transport
- Batteries are filled with acid.
- Always store and transport batteries upright
and prevent from tilting so that no acid can
escape.
- Store in a cool and dry place.
- Do not remove the protective cap from the
positive terminal.
- Run a FIFO (first in-first out)warehouse
management system.
2. Initial operation
- The batteries are filled with acid at a density of
1.28g/ml during the manufacturing process and
are ready for use.
- Recharge in case of insufficient starting power
(cf. section 4).
3. Installation in the vehicle and removal from
the vehicle
- Switch off the engine and all electrical
equipment.

slightly with battery grease.
- When installing, first connect the positive
terminal, and check the terminal clamps for
tight fit.
- After having fitted the battery in the vehicle,
remove the protective cap from the positive
terminal, and place it on the terminal of the
replaced battery in order to prevent short
circuits and possible sparks.
- Use parts from the replaced battery, such as
the terminal covers, elbows, vent pipe
connection and terminal holders (where
applicable); use available or supplied filler caps.
- Leave at least one vent open, otherwise there
is a danger of explosion. This also applies
when old batteries are returned.
4. Charging
- Remove the battery from the vehicle;
disconnect the lead of the negative terminal first.

19 ERVICE IN TRUCTION
All the hydraulic hoses should be regularly inspected for chafing and leaks. The hydraulic system is
pressurized to over 150 Bar (2175 PSI) 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.
CHECK HO E
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 between
the min and max lines on the tank (about 15 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.

CHECK FITTING
The Timberwolf TW 150VTR/FTR 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 required torque (see 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.
