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
SAFE 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'S PERSONAL 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.

GENERAL SAFETY MATTERS
DO’S AND DON’TS
DO NOT operate chipper unless available light is
sufficient to see clearly.
DO NOT use or attempt to start the chipper with-
out the feed funnel, guards and discharge unit
securely in place.
DO NOT stand directly in front of the feed funnel
when using the chipper. Stand to one side.
DO NOT allow -
DO NOT smoke when refuelling.
DO NOT let anyone who has not received
instruction operate the machine.
DO NOT climb on the machine at any time.
DO NOT handle material that is partially engaged
in the machine.
DO NOT touch any exposed wiring while machine
is running.
DO NOT use the chipper inside buildings.
- to enter the machine, as damage is likely.
ALWAYS stop the chipper engine before making
any adjustments, refuelling or cleaning.
ALWAYS check rotor has stopped rotating and
remove chipper ignition key before maintenance
of any kind, or whenever the machine is to be left
unattended.
ALWAYS check the machine is well supported and
cannot move.
ALWAYS operate the chipper with the engine set
to maximum speed when chipping.
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 operate the chipper in a well ventilated
area - exhaust fumes are dangerous.

WHEN towing a chipper the maximum speed limit is 60 mph.
ON rough or bumpy road surfaces reduce speed accordingly to protect your machine from
unnecessary vibration.
WHEN towing off road be aware of objects that may catch the chipper undergear.
WHEN towing off road ensure inclination is not excessive.
AVOID excessively pot holed ground.
WHEN reversing the chipper the short wheel base will react quickly to steering.
ALWAYS check the discharge clamps are tight before travelling.
KEEP tyre pressures inflated to 4.8 bar or 70 psi.
CHECK wheel nuts are tightened to 240lbs ft (325Nm).
CLEAR loose chippings and debris from the machine before travelling.
ENSURE the feed funnel is closed and the catches are properly engaged before travelling.
SAFE TRANSPORTATION
WARNING DO NOT RIDE ON THE CHIPPER WHEN IT IS BEING TOWED.
HITCHING ONTO THE TOW BALL
OPERATING INSTRUCTIONS 8
TIMBERWOLF
TW 350DHB(t)
CHECK the ball head is well greased.
WIND jockey wheel assembly anticlockwise until the tow head is above the height of the ball
hitch on the vehicle.
REVERSE the vehicle so the ball hitch is directly below the tow head.
ATTACH the breakaway cable to a strong point on the vehicle, not the ball hitch.
GRASP handle on tow head and pull up handle until it catches and remains in the ‘up’ position.
WIND the jockey wheel assembly clockwise, to lower the tow head onto the ball hitch.
RELEASE handle and continue to wind jockey wheel clockwise. The tow head should snap
into place on the ball hitch. If it doesn't, repeat previous 2 steps.
WIND jockey wheel up until fully retracted and the jockey wheel frame folds into its tow position.
CONNECT electrical plug to socket on rear of towing vehicle and check operation of all the
trailer and vehicle lights.
THE chipper is now properly attached to the vehicle.
CHECK turntable is located in the ‘tow’
position and the safety catch is locked in
position. TOW POSITION IS ALWAYS WITH
THE FUNNEL IN-LINE WITH TOWING
VEHICLE.
CHECK prop stands are fully retracted.
Funnel in correct
towing position
Do not tow with
rotated funnel

TIMBERWOLF
TW 350DHB(t)
9OPERATING INSTRUCTIONS
DISCONNECT the electrical cable from the vehicle socket.
RELEASE breakaway cable.
WIND the jockey wheel assembly anticlockwise until it just starts to take the weight of the chipper.
GRASP the tow head handle and pull up until it catches and remains in the ‘up’ position.
APPLY the handbrake.
CONTINUE to wind the jockey wheel anticlockwise. This should lift the tow head clear of the ball
hitch.
DRIVE the vehicle clear of the chipper.
WIND the jockey wheel assembly to a suitable point where the chipper is level.
THE chipper is now fully detached from the vehicle.
LOWER the two prop stands to stabilise the chipper.
The TW350DHB (t) A chipper has the ability to adjust the towhead height to correspond with the
vehicles towing point.
The preferred towing angle of any chipper is with the chassis level to the ground. The adjustable head
has the ability to move between 300mm from the ground to 875mm giving an overall adjustment of
575mm.
The towhead latch and handbrake
fundamentally work the same as a fixed
standard towhead, however the front section of
the head is retained in position via a locking ring
and single clamp handle.
To adjust the height the locking handle located
on the side of the head (1) is turned in an
anticlockwise direction to allow for the locking
ring to disengage from its apposing ring. An
internal damper is fitter to support the heads
weight allowing both hands free to adjust the
height. Once the desired height has been
achieved the locking handle is turned clockwise
until tight. The latching of the hitch is as normal
as is the fitting of the light plug and breakaway cable as outlined in the ‘Hitching onto the tow ball’
section on page 8 .
