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 for the C40 is 178 mm
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 C40 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. The outlet chute height can also be adjusted by cranking
the swivel handle on the back of the outlet chute.
Additionally, the top of the outlet chute is fitted with two deflector plates that can be
adjusted to control the angle and distance of discharged material. A wingnut is located on
the side of the upper deflector to lock it in place.

Feed roller control
The C40 is equipped with a feed roller which facilitates the process of feeding material
into the machine. The feed roller is controlled via the yellow control bar which surrounds
the inlet table. The control bar has three settings:
1) Reverse
2) Neutral
3) Feed
When the bar is fully pushed in, the feed roller will be set to reverse. When the bar is fully
pulled out, the feed roller will feed material. The neutral position lies between the reverse
and feed positions.
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 roller 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 RPM) 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 five 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.
Engine LED panel
The engine LED panel has a self-contained engine safety shutdown system as well as a number of warning indicators.
Feed –Neutral –Reverse
1 –System OK indicator
2 –Low oil pressure
3 –Low alternator output
4 –Air filter restriction

Safe operating procedures
Wear safety equipment: Safety glasses and hearing protection
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 the chipper is positioned so that there is a minimum inlet table height of 600 mm off the 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:

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 / 178 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
Enter the inlet chute
Get on, or lean over the feed table
Put hands or any other part of the body or clothing:
Inside the inlet chute
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 5 of this manual.
DO NOT:
Ensure the rotor is disengaged by winding the
engagement handle in the clock-wise direction until
the handle comes to a stop (located next to the control
panel).
Additionally, ensure the throttle control is set to idle.

Shutdown procedure
On the control panel, insert and turn the key clockwise
into the start position while simultaneously holding the
oil pressure switch bypass button. Allow the engine to
warm up for 1-2 minutes.
Increase the throttle to 1/3 (up to the first notch on the
throttle control gate). Gradually and slowly engage the
rotor by winding the engagement handle in the counter
clock-wise direction until it comes to a stop. This should
be done slowly to allow enough time for the cutting
rotor to pick up speed without stalling the engine.
Increase throttle to full for chipping (move the throttle
lever to the left-most position).
Note: Engine must run at full throttle for the automatic
feed and feed roller to operate. Refer to the
‘Automatic Feed Controller’ section on page 4 to set
the automatic feed control to the desired setting.
To shut the machine down, move the throttle control
lever to the idle position (far-right position).

Remove the knives for sharpening:
Open the rotor housing cover by removing the
two housing cover locking bolts with a 19 mm
spanner, then lift the rotor housing cover to
access the cutting rotor. Rotate the cutting rotor
to gain access to the knives, then insert the rotor
pin (normally located under the control panel)
into the housing and through the cut-out in the
rotor to lock it in place.
Using a 24 mm spanner and a 14 mm Allen key,
remove the knives from the rotor. There are three
bolts that you must remove on each knife to do
so.
Be careful not to drop the bolts or knives
into the chipper.
A stick magnet can be used to retrieve
them if this does occur.
Measure the width of the knife and check that it
will be at least 96 mm after sharpening.
If the knives will be shorter than 105 mm, then
the knives should be replaced. Please contact
your nearest Hansa dealer.
Sharpen the knives:
Sharpen the knives on a surface grinder. A cutting
angle of 36 ° is critical for the performance of the
chipper. Make sure there is plenty of coolant used
when grinding to avoid softening of the steel knives.
Note: You do not need to sharpen your knives unless
both sides of the reversible knives have been used.

Reinstall the knives:
Clean all mounting surfaces and remount the knives
in the reverse procedure. Torque the knife clamping
nuts up to 190 Nm.
After sharpening, the width of the knives will have
been reduced, therefore the gap between the knives
and anvil may require adjustment. There should be
3 mm of clearance between the knife and the anvil.
If there is not enough clearance, the knife edge may
touch the anvil through deflection when cutting
heavy branches and damage the sharp edge. Too
much clearance will allow small twigs and fibrous
materials to be dragged through without being cut.
To adjust the gap between the knives and the anvil,
first loosen the locking nuts from the adjustment
bolts on the anvil mounting plate using a 16 mm
spanner. Now tighten or loosen the two adjustment
bolts. Tightening these bolts will cause the anvil
mounting plate to slide further along the slotted
holes. Ensure you tighten the two bolts evenly to
avoid setting the anvil on an angle.
Once the correct anvil position has been set, ensure
the locking nuts on the adjustment bolts are
tightened. Additionally, ensure the clamping nuts
are torqued to 44 Nm.
Remove the rotor pin and turn the rotor slowly by
hand to check that it turns freely.
Close and secure the outlet chute.
WARNING! Every time the knife clamping bolts are torqued up to 190 Nm and loosened off again, the life of the bolts is
reduced. The knife clamping bolts must be replaced at most after every six sharpens. Contact Hansa for replacement
bolts (m16x50 countersunk bolts of grade 12.9 or higher). Use only genuine Hansa bolts.

Anvil adjustment
Whenever the chipper knives are inspected/sharpened, the condition of the anvil should also be checked. If the edge of the anvil
is significantly rounded and/or uneven, then it should be reversed or replaced. Typically, the anvil will maintain its sharp edge for
about 500 hours of operation.
Anvil replacement
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.
To remove the anvil, you must remove the three
countersink clamping bolts using a 16 mm socket
and extension. If the bolt head turns, hold it with
a 6 mm Allen key.
Note: Do NOT use the Allen key to turn the bolt;
turn only the nut.
Note: Ensure the gap between the knives and the
edge of the anvil is 3 mm. If not, then the anvil can
be adjusted via the two adjustment bolts between
the clamping bolts.
If the other side of the anvil hasn’t been used yet: rotate the anvil 180 degrees and place it back on the feed roller
housing wall. If both sides of the anvil are blunt: remove the anvil and replace it with a new one. Contact Hansa
if a replacement anvil is required.
Tighten the clamping bolts back up using a 16 mm socket, ensuring there is a spring washer between the clamping
plate and each nut. Torque the nuts to 44 Nm.

Belt tension
Correct belt tension is crucial for minimising belt wear and maximising machine efficiency. To check the belt tension, fully engage
the belt then open the bonnet. There should be approximately 5 mm deflection in the belt when pressing firmly on the belt (as per
the image below). Alternatively, the tension can also be checked by looking at the tensioning device from underneath the machine;
the notch on the idler arm should line up with ‘15°’ on the tensioner (as per the image below). If required, adjust belt tension.
Note: After using the machine for the first time, or after replacing the belts, it is recommended to check the tension again after the
first 5 hours of operation, as the belt will stretch as it wears into the system.
Belt tension adjustment
The belt tension can be adjusted by moving the M16 nyloc adjustment nut (below the machined engagement block) up or down
the engagement thread. You will need to use a 24 mm spanner to do so. The belt tension will increase as the nut is moved down
the thread.
Belt replacement
If the belts in your chipper look similar to any of the following images or are clearly broken, then they need to be replaced.
To remove the belts, open the bonnet and fully disengage the belts. The C40 requires three SPB1260 belts.

Hydraulic pump belt adjustment
The hydraulic pump is driven by a synchronous belt. The belt does not require any tension, however the belt should not have any
slack either. The belt can be adjusted by loosening the four mounting bolts (using a 13 mm spanner) and moving the pump/pulley
up or down the slotted holes (as per the image below). The lower two bolts are best accessed from beneath the machine. If the
belt is damaged in any way, contact Hansa for a replacement.
Greasing bearings & pivot points
Points that need to be greased are as follows (as per the diagram on the following page):
1. Two bearings on the rotor shaft, one under the engine cover and the other above the inlet opening

2. Two bearings on the feed wheel
3. Two bearings on either side of the feed wheel pivot
4. Four grease nipples for pivoting the outlet chute
5. One grease nipple on the engine engagement screw (must be accessed from below the machine)
These points must be greased every 50 operating hours. Ensure a suitable grease is used (bearing grease or all-purpose grease).
Hydraulic system
Replace oil filter after first 50 hours, then every 250 hours.
The hydraulic oil should be changed every 800 hours. It is a closed system therefore it should not become contaminated, however
if contamination is detected oil should be changed. Use only a good quality brand, 32 grade hydraulic oil.
Fill the hydraulic oil tank so that the oil level is at the line indicated by the cold oil level label to the left of the oil level indicator.
The level should be checked with the engine off while the oil is cold
For any repair in the hydraulic system, contact Hansa Products or seek advice from a competent service agent.
Engine servicing
For servicing of the engine, please refer to the engine manual. Change oil, oil filter, fuel filter and air filter as recommended in the
manual. Ensure the correct engine oil is used.
Other servicing
✓Check all bolts and other fasteners for the correct torque setting

✓Check wheel nuts and U-bolts are fastened correctly
✓Check and repack wheel bearings with grease every 12 months
✓Check air pressure in tires. Inflate to pressure as indicated on the tire
✓Check safety chains and hitch
Rotor bearing replacement
Replacing rotor bearing on engine side of rotor:
1. Remove engine pulley by unbolting both grub screws in bush. Then screw one grub screw into the third hole and tighten
until the pulley separates from the bush. Slide bush off the shaft, followed by the pulley.
2. Remove two grub screws in the bearing.
3. Remove M16 nuts and bolts bolting the bearing to the housing.
4. Remove and replace bearing.
5. When replacing the pulley ensure the rotor pulley is lined up to the engine pulley with a straight edge. Ensure the grub
screws are tightened evenly so the pulley is tightened evenly.
6. The gap between the end of the sensor and the sensing plate should be approximately 3 mm. Adjust the sensor
accordingly. If it is set further away, then the sensor may not work properly and therefore the AFC will not work.
Replacing rotor bearing on inlet chute side of rotor:
It is recommended to have this bearing replaced by a specialist Hansa dealer.
Tyre Pressure
The recommended tyre pressure is 65 Psi.
