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.

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.

OPERATING INSTRUCTIONS 11
STARTING TO CHIP
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.
!!
CHIPPING
Wood up to 190mm 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 by the speed control 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 rotation at the correct speed. If
the rollers continue to stall in the 'forward feed' or 'reverse feed' position push the RED STOP
BUTTON, turn engine off, remove ignition key and investigate.
BEFORE USING THE CHIPPER
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.

OPERATING INSTRUCTIONS 12
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 engine and remove the keys.
REMOVE the two rotor housing bolts.
OPEN the rotor housing fully.
THE material causing the blockage should fall clear.
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.
EMPTY loose debris from inside the rotor housing.
CHECK that the discharge tube is clear before continuing.
THE rotor housing does not have to be completely clear to continue.
SHUT the rotor housing and replace both bolts securely.
RESTART the engine.
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.
!!
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.

TENSION DRIVE BELTS
CHECK HOSES
All the hydraulic hoses should be regularly inspected for chafing and leaks. The hydraulic system is
pressurized to 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.
The TW 190TR 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 .

work it should be done more frequently. 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.

SAFE MAINTENANCE
Solidly support the under carriage if it needs to be lifted up for maintenance.
Hydraulic systems may get very hot after working.
Keep all components in good condition as they are exposed to high pressures.
Immediately repair damage and replace worn or broken items.
Keep the tracks clean, removing excss oil, grease and dirt.
Check for oil leaks and damaged hoses.
Only use recommended lubricants. Do not mix different brands.
Use only Hinowa spare parts.
Keep track stretcher grease nipples clean.
TRACK BASE MAINTENANCE
To fill with oil, track the machine until the gearbox casing is level with a
plug positioned at 12 o’clock as shown. Unscrew the two plugs and fill
from the upper hole until oil reaches the level of the lower hole.
REPLACEMENT OF OIL IN THE TRACK DRIVE UNIT
To drain the oil, track the machine until a plug is at 6 o’clock as shown.
Unscrew both plugs and allow oil to discharge into a suitable container.
Dispose of waste oil in a safe and approved way.
DRAINING THE OIL IN THE TRACK DRIVE UNIT
REDUCTION UNIT OIL TYPES
We recommend, for track drive gearboxes, using gear oils with E>P. additives and viscosity to SAE
80W/90 or ISO VG 150. Continuous duty temperature must not exceed 90oC.
Maintenance intervals are only guidelines. They should be increased if severe conditions are
encountered. Dispose of lubricants only in accordance with current environmental protection regulations.

CHECKING TRACK TENSION
1. Stop your machine on a flat
and solid surface.
2. Lift it in safe conditions and
put stable supports under
the undercarriage frame to
properly support it.
3. Measure distance A at the
central roller of the undercarriage from the bottom of the roller to the rigid inside surface of the
rubber track. Track tension is normal if dimension A is between 10 and 15 mm.
4. Adjust tension as described in the following paragraph if track tension does not comply with
these dimensions (loose or too tight).
A
TRACK LOOSENING/TIGHTENING PROCEDURES
Track tension is maintained by grease in the adjuster unit. More grease will increase track tension,
less grease will decrease it.
The grease contained in the hydraulic track is pressurized. Never loosen the grease valve (No.2, fig.
27). for more than one turn. If the valve is loosened too much you risk expelling grease under
pressure and possible serious injury to the machine operator. Never loosen the grease nipple (No.5,
fig. 27). Remove gravel or mud when they are jammed between the sprocket and the track link before
loosening the track.
1. Remove the screws and take off the cover to access the
adjustment system.
2. To loosen the track turn the valve counter-clockwise no more than
one turn. One turn of valve is sufficient for loosening the track.
3. If grease does not start to drain out then slowly rotate the track.
WARNING
It is not normal for the track to remain too tight after turning the valve counter-
clockwise or for it to remain loose after introducing grease into the grease
nipple. Never try to remove the tracks or disassemble the track-stretching
cylinder since pressure of the grease inside the track is extremely dangerous.

4. When you have obtained correct track tension then turn valve
clockwise and tighten it. Clean all traces of extruded grease.
5. To stretch the track connect a grease gun to grease nipple and
add grease until track tension falls within specified values.
