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 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.

SAFE WORKING
DO’S AND DONT’S
GENERAL SAFETY MATTERS
DO NOT use chipper unless available light is
sufficient to see clearly.
DO NOT use or attempt to start the chipper
without the feed funnel, belt guard, guards and
discharge unit securely in place.
DO NOT start the chipper running unless properly
guarded.
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.
Petrol is explosive!
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 whilst
machine is running.
- to enter the machine, as damage is likely.
BRICKS STRING CLOTH PLASTIC STONES
METAL GLASS RUBBER ROOTS BEDDING
PLANTS
ALWAYS stop the chipper engine before making
any adjustments, refuelling, or cleaning.
ALWAYS check machine has stopped rotating
and remove chipper 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 maximum
speed.
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.

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 STOP BAR = This is the large red bar that surrounds the feed tray 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.
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.
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.

OPERATING INSTRUCTIONS 9
CRAWLER TRACK CONTROLS
The chipper is designed to operate in either chipper or crawler mode, but not both at the same time.
CHIPPING 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. 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 the 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. Manouvering the machine in tight spaces
and whilst loading and unloading should be done with the engine on low speed.
TRACK
CHIP
fig 6.
AUTO CONTROLS
The speed control unit controls the feed rate of the material going into the chipping chamber. If the
engine speed is below the predetermined level the speed control 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.
There are two ways of stopping the TW 190TR chipper in the event of an emergency.
STOPPING THE ROLLERS
Pushing the red button on the roller control box will stop the rollers immediately. This action will not
allow any further material to be fed in until it is reset. The button will stay in the 'pushed in' position.
To reset the button and continue working the button must be pulled out.
STOPPING THE 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 again to reset it.
EMERGENCY STOPPING
