Preventing accidents is the responsibility of every equipment operator. The operator is responsible for any accidents or hazards
occurring to people or their property. Ensure every operator is familiar with the safe operation procedures and controls of the
machine, how to identify hazards, and the steps required to avoid injury while handling and operating the chipper. Relevant
information is contained in this manual.
Do NOT modify the design of the chipper.
Operator competency
Ensure that every person operating the chipper understands and follows the safe operating and maintenance procedures
as detailed in this manual.
Do NOT allow persons below the age of 18 to operate the chipper. Additionally, local regulations may restrict the age of
the operator.
Do NOT allow persons with reduced physical, sensory or mental capabilities, or lack of experience and knowledge to

Towing safety
Rotate the discharge chute to face the opposite direction of the towing vehicle before towing and lock into position.
Lock the feed table in the up position.
Do not exceed maximum towing speed of 90km/hr.
Connect the tow coupling to the towing vehicle (check the ball dimensions are the same as the coupling).
Connect safety chain with shackle.
If the machine is fitted with brakes, check handbrake is off and road brakes are on by removing the reversing lever.
Plug in lights and check they are operational.
Check wheel nuts and axle U-bolts periodically to make sure they are secure.
Ensure the jockey wheel is in the up position and locked away during transport.
Ensure the rotating assembly is positioned facing forwards (with the engine at the front, feed chute at the rear) and the
chassis rotation locking pins are down in the locked position.
Operation
The chipper is self-feeding and has a large inlet opening. It can process:
•Prunings, stalks, vines, leaves, roots and vegetable matter, paper and cardboard
•Freshly cut material is better to process than dry material
•Maximum capacity is 160 mm diameter branches
It is recommended to keep a wooden stick handy, approx. 60 mm diameter x 1000 mm long for:
•Pushing in short, brushy and very leafy materials
•Keeping the inlet table clear
Outlet chute adjustment
The C27 is fitted with a freely rotating outlet chute, allowing the operator to precisely
control the direction of material discharge from the machine. The chute can easily be
adjusted by undoing the clamping bolt, adjusting the outlet chute direction as needed, then
doing the clamping bolt back up.
Additionally, the end of the outlet chute is fitted with two deflector plates that you can
adjust to control the angle and distance that material is discharged. A wingnut is located on
the side of the upper deflector to lock it in place.
360-degree turntable adjustment
The chipping components of the C27 are coupled to the chassis via
a freely rotating turntable. This allows the operator to feed material
into the chipper from any direction, eliminating the time and effort
spent repositioning the machine, and allowing you to use the
chipper while still being coupled to the tow vehicle. To reposition
the turntable, lift the locking pins on each side of the chipper, rotate
the chipper, then resecure the pins. Check the table is locked
properly by ensuring each pin locks into one of the 24 positions on
the base of the turntable.

Note: the body of the chipper is rather heavy and it may take significant force to rotate.
Feed roller control
The C27 is equipped with a feed roller which draws material into the machine. The feed roller is controlled via both the yellow
control bar which surrounds the inlet table and the capacitive touch button on the side of the inlet table. Pushing the control bar
in (towards the body of the chipper) stops the feed roller. Pulling it out (away from the body of the chipper) enables the feed roller.
When the control bar is in the ‘enabled’ position, touching the capacitive touch button will start the feed roller. When pressed
again, it will toggle between forward rotation and reverse rotation of the feed roller.
Automatic Feed Controller (AFC)
The feed roller is fitted with an electronic automatic feed control system which is designed to limit the feed rate of material into
the machine in order to prevent the engine from stalling.
This system eliminates the need to control the speed at which the branches are fed into the chipper manually. A sensor detects the
RPM of the rotor; once this speed drops to a pre-set level the feed roller stops and the branch stops feeding into the machine. The
engine then picks up in RPM and once it reaches a pre-set speed the feed-roller will start feeding again. The feed wheel will also
reverse back slightly after stopping (reducing the friction between the wood and knives), resulting in a quicker engine recovery.
The feed roller will only work once the engine is turned on and the engine has reached full throttle after engaging the rotor. If the
green LED light on the AFC controller is flashing this indicates the feed roller isn’t turning. When this changes to a solid green light
(when the engine reaches maximum throttle of 3000RPM) the feed roller will be operational.
The AFC has 19 different pre-set positions at which the feed will stop.
Adjusting the AutoTrip setting:
1. Turn the ignition key into the ‘ON’ position. Alternatively, this can be adjusted when the machine is in operation.
2. The version number will initially be displayed on the LCD display, wait until this clears.
3. Push the ‘Menu’ button once.
4. Adjust the AutoTrip setting down using the ‘Menu’ button or up using the ‘Set’ button. There are 19 different positions at
which the feed will stop. At setting 1 the engine is dropping further in RPM, whereas at setting 19 the engine is only
dropping marginally in RPM before the feed roller stops. Adjust to a setting which is most suitable to you. Once adjusted
the screen will return to the Hour meter / Tachometer display after 5 seconds, saving the desired setting.
If there are any problems with the electronic automatic feed system, the chipper can be used with the auto-feed disabled. To
disable auto-feed, adjust the AutoTrip setting down to 0 or up to 20.
WARNING! Be careful using the machine with auto-feed disabled as the machine can be stalled easily.
Hour meter / tachometer
The LCD display will toggle between the current engine RPM and machine hours every 5 seconds. Alternatively, the operator can
toggle between the two by pushing the ‘Set’ button.

Emergency stop
The emergency stop acts as an immediate kill switch to the engine. It does not stop the rotor from spinning. The rotor will continue
to spin for some time due to its rotational inertia. To engage the emergency stop, push the red button. To disengage the emergency
stop, twist the red button clockwise until it releases outwards.
Use it when foreign matter such as sand, stones or metal enter the inlet chute
Use it in response to an immediate hazard/danger to an operator or onlooker
Follow the regular shutdown procedure in addition to using the emergency stop
Inspect the machine before resetting the emergency stop
Under normal conditions, Do NOT use the emergency stop in place of the regular shutdown procedure

Safe operating procedures
Wear safety equipment: Safety glasses and earmuffs must be
worn at all times
Wear work gloves: The wearing of work gloves is optional but
highly recommended - ensure that the gloves fit tightly
Do NOT wear loose fitting gloves or gloves with long cuffs
Loose gloves may get snagged by branches, which could result in the operator being pulled into the chipper
Tie long hair up
Long hair could be snagged by a branch and may be pulled into chipper
Wear clothes that sit tightly
Avoid scarves and any items that can get caught in the chipper or snagged on branches
Place the chipper on even ground and direct outlet chute onto soft ground
Ensure exhaust is pointing away from the working area and downwind from the operator and onlookers
Keep proper balance and footing at all times and stand at the same level as the chipper
Do NOT climb onto the inlet table to push material into the feed roller
Keep your face and body away from the inlet chute. Stand to the side of the inlet table while feeding material into the
chipper
Standing to the side gives better access to the control bar and helps in keeping clear from flying debris
Feed only freshly cut material into the chipper
Do NOT feed in materials covered in gravel, stones and dirt as this can rebound, injure the operator and damage
the machinery
Prune to a size that suits the chipper’s capabilities
Pre-cut side branches
The branch will ‘self-feed’ more efficiently
Keep the engine clean of debris and other accumulations
This prevents damage to the engine or possible fire
Feed limbs and branches through butt end first, leaving the bushy head on
This helps guide the limb down the inlet chute
It reduces spinning and the occurrence of ejection of small pieces back up the inlet chute
Feed soft materials intermittently with branches
The wood chips tend to clean out any soft residue left in the chipper
The chipper can clog up with soft, wet or fibrous materials
Keep well clear of the outlet chute discharge area, even when the chipper is not currently processing material
High velocity, sharp discharge can cause serious injury
Keep the outlet free of blockage
If blockage occurs, turn the engine off and wait for rotor to stop spinning. Open the outlet chute and remove
material until the outlet chute is clear
Keep the feed roller free of blockage
If blockage occurs, turn the engine off and wait for rotor to stop spinning. Remove the feed roller guard by
unhooking the four rubber latches. Unhook the springs from the base of the chassis. Lift the swing arm up and
insert the rotor pin (located underneath the control panel) into the tab on the housing to lock the swing arm in
place (as per the diagram below). You may now safely clear the blockage. Remove the rotor pin, lower the feed
roller, reposition the springs, then replace the guard
Turn off the engine whenever you leave the work area
DO:
Rotor pin
Feed roller motor
Swing arm

Run the chipper in an enclosed area
Exhaust fumes contain carbon monoxide which is poisonous, colourless, odourless, and tasteless
Operate the chipper wearing loose clothing and untied long hair
Stand at a higher level than the base of the chipper when feeding material into it
Feed flax and cabbage tree leaves into the machine
These stringy materials can wrap around the rotor shaft and work their way into the bearing.
If any stringy material becomes wrapped around the rotor shaft, remove it before it works itself into the bearing.
Process old materials such as dried wooden branches
They get very hard and springy when dried out
They are more awkward to handle
The knives dull much quicker
Feed short, stubby pieces of wood into the chipper
They bounce and spin in the inlet chute
Feed short stubby pieces together with longer pieces
Feed branches that are too large (max 160 mm branch diameter)
The chipper engine will stall, which could result in damage to the engine or drive belts
Put soil, sand, grit, stones or pieces of metal into the chipper
This will damage the sharp edge of the cutting knives and can rebound and injure the operator
Put root balls and dead wood into the chipper
This dulls the knives quickly
Overload the chipper
If the cutting rotor is slowing down, feed the material in slower
Transport the chipper while the engine is running
Tamper with the engine governor settings on the chipper
The governor controls the maximum safe operating speed and protects the engine and all moving parts from
damage caused by overspeed
Operate the chipper with blunt knives
This causes excessive vibration which may result in damage to the chipper
Remove any guards on the chipper unless the engine is turned off and the cutting rotor has come to a complete standstill
Put hands or any other part of the body or clothing:
Inside the feed chute past the rubber flap
Inside or near the opening of the discharge chute
Near any moving part
Use the feed control bar as a handle to manoeuvre the machine
Starting procedure
Before proceeding, ensure the ‘safe setup procedure’ has been followed on page 6 of this manual.
DO NOT:
Ensure the rotor is disengaged by winding the
engagement handle in the counter clock-wise direction
until the handle comes to a stop (located next to the
control panel).
