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 110 mm diameter branches
It is helpful (but not required) to keep a wooden stick handy, approx. 60 mm diameter x 600 mm long for:
•Pushing in short, brushy and very leafy materials
•Keeping the inlet chute clear
Safe setup procedure
Before you start:
Ensure the chipper is positioned in an open area and on firm level ground
Ensure that the outlet chute is discharged onto soft ground (e.g. grass)
Do NOT allow the outlet chute to discharge chip onto hard surfaces (such as a paved or gravel surface)
Ejected material can rebound and cause injury
Keep children, pets and spectators clear of the work area at all times
Do NOT operate the chipper where there is a hazard to onlookers
Do NOT allow any person under the age of 16 to operate the chipper
Check:
That all screws, nuts, bolts, and other fasteners are properly secured
That all chipper components are in place and in good condition.
If any parts are worn or damaged, contact Hansa for replacements
That fuel and engine oil levels are above the minimum levels
That the fuel cap is secured and there is no fuel leaking from the tank
That the inlet chute and housing are clear of any leftover material
That all labels are in good condition and easily legible
Replace damaged or unreadable labels
View photos of labels in the ‘Decals’ section
Refuelling:
Take extra care in handling fuels
They are flammable and vapors are explosive
Use only an approved fuel container

8
Keep your face and body away from the inlet chute
Stand clear of the discharge zone, even when no material is being fed into the chipper
Place the chipper on even ground and direct the outlet chute onto soft ground
Ensure the 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 overreach
Do NOT run near the machine
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
Branches 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 foliage 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
Hold larger branches back and feed the chipper with care until you are familiar with its capacity
The engine will slow down or stall if the branch is too large
Feed longer pieces together with short stubby pieces
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 the outlet free of blockage
If a 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
As the discharge material piles up
Move the chipper to direct the outlet chute away from the pile, or move the processed material
to avoid blocking
Turn off the engine whenever you leave the work area
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
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
The chipper can easily stall
Put soil, sand, grit, stones, glass, pieces of metal or other foreign objects 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 (maximum branch diameter 130 mm)
If the cutting rotor is slowing down, feed the material in slower
Allow processed material to build up in the discharge area as this can:
Prevent proper discharge
Result in kickback of material through the feed opening
Transport the chipper while the engine is running
Tamper with the engine governor settings on the chipper
DO NOT:

Hansa C16 O&M Manual - OM-009 Revision G 26/09/2019

9
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
Move or tilt the chipper while it is running
Touch any guards or stick hands between guards while the chipper is running
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
Remove any guards on the chipper unless the engine is turned off and the cutting rotor has come to a complete standstill

Knife re-sharpening and knife replacement
How do I know that the knives need re-sharpening?
Chipper loses its self-feeding action with blunt knives
Material has to be pushed in
Material comes out in long strips
Blunt knives will cause excessive vibration
Blunt knives result in damage to the chipper
How to re-sharpen the knives:
If you don’t have a surface grinder or are unsure how to re-sharpen the knives, contact a professional saw doctor or Hansa to
arrange re-sharpening.
Tools and materials required for re-sharpening (approx. 40 mins):
•13 mm spanner
•5 mm hexagonal Allen key
•A stick magnet (optional)
•Surface grinder
•Coolant
Remove the knives for sharpening
Open the rotor housing cover by removing the two housing cover locking bolts with an 18 mm spanner, then lift
the rotor housing cover to access the cutting rotor.
Rotate the cutting rotor to gain access to the knives, then engage the belt drive to stop the cutting rotor from
rotating.
Use a 13 mm spanner to remove the knives from the cutting rotor. There are five
bolts that you must remove 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 46 mm after
sharpening.
If the knives will be shorter than 46 mm, then the knives should be replaced.
Please contact your nearest Hansa dealer.
Sharpen the knives
WARNING! Do NOT operate your chipper with blunt knives.
WARNING! Be careful when working around the sharp knives. Be aware that even though the motor is off, the cutting
means can still move.

Sharpen the knives on a surface grinder. A cutting angle of 36 ° is critical for the
performance of the chipper. Make sure plenty of coolant is used when grinding to
avoid softening of the steel knives.
Reinstall the knives
Clean all mounting surfaces and remount
the knives in the reverse procedure.
Note: Be sure to replace the knives the
correct way around (as shown in the
diagram). Only tighten the clamping bolts
enough to hold the knives in place during
adjustment. Do not tighten them fully until
step 7.
Adjust the knives initially using the
adjustment bolts to protrude the edge of
the knife just past the edge of the knife
holding block.
After sharpening, the width of the knives
will have been reduced, therefore the gap
between the knives and anvil may require
adjustment. This gap is tapered out slightly
to allow for a small amount of movement in
the cutting rotor as it bites into the wood.
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.
Adjust the knife in or out using the two
adjustment bolts to achieve the correct
clearance between the knife and anvil. The
clearance between the knife and anvil
should be approximately 1 mm on the
inside closest to the bearing and 3 mm on
the outside closest to the edge of the
cutting rotor (refer to diagram for more
detail).

After the correct clearance is set, fully
tighten the clamping bolts using a torque
wrench to 35 Nm and tighten the locking
nuts on the adjustment bolts.
Note: Before adjusting the knives, ensure
the gap between the holding block and the
anvil is 4 - 5 mm. If not, then the anvil can
be adjusted through the mounting slots.
Once the position has been set, tighten the
three M10 countersunk anvil bolts and
torque to 44 Nm, then make further
adjustments with the knives as described
above.
Turn the cutting rotor slowly by hand to
check that it turns freely.
Close and secure the outlet chute.
Anvil adjustment/replacement
When cutting edge of the anvil is dull, the anvil may be reversed can be reversed. Each edge of the anvil will typically last for several
hundred hours of operation. When both edges are worn, the anvil will need to be replaced.
To access the anvil the inlet chute needs to be removed (use the reverse procedure to fit the inlet on page 3). A 5 mm Allen key,
17 mm socket and an extension are required to remove the anvil.
With the knives removed or set right back, the gap between the knife holding block and anvil should be 4 - 5 mm. The position of
the anvil can be adjusted through the mounting slots. When this has been set, tighten the three M10 countersunk anvil bolts using
a torque wrench to 44 Nm and then make further adjustments with the knives as described above.
Turn the cutting rotor slowly by hand to check that it turns freely.
Engine servicing
For servicing of the engine, please refer to the Briggs and Stratton Vanguard engine manual.
Engine oil
It is recommended you check the oil level every time you use your chipper. To check the oil level,
remove and clean the dipstick, then fully reinsert the dipstick. Remove it again and check the oil level
indicated at the base of the dipstick. The oil level should reach the upper dot near the base of the
dipstick. Fill as necessary, but do not overfill. For optimal performance of your chipper, the engine oil
should be completely changed every 100 operating hours, or roughly once every 12 months on average.
WARNING! Every time the knife clamping bolts are torqued up to 35 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 (m8x35 bolts of grade 10.9 or higher). Use only genuine Hansa bolts.

If the engine oil needs to be changed, follow these steps:
Run the engine for 1-2 minutes in order to warm up the
oil. Switch the engine off after the oil is warm. Place a
container underneath the engine. Remove oil filler cap
and oil drain plug (using a 10 mm spanner), then let the
oil drain into the container through the opening in the
chassis.
Screw the oil outlet drain plug back in and fill the engine with 1.4 litres of SAE 10W30 or SAE 10W40 through the
oil filler cap.
Recheck the oil level. It should be close to, but not above, the upper limit indicator on the dipstick. Screw the oil
filler cap back on. Dispose of the used engine oil in an environmentally sensitive way.
Belt tension
Correct belt tension is crucial for minimising belt wear and maximising machine efficiency. To check the belt tension, first ensure
the belt drive is disengaged by turning the engagement handle anticlockwise. Then, from the fully disengaged position, gently turn
the engagement handle clockwise until you feel it start to resist. From this position, turn the engagement handle clockwise. If the
tension is set correctly, the handle should turn one full revolution clockwise before coming to a stop. If there is a difference greater
than 1/6 of a revolution either clockwise or anticlockwise from one full revolution, then the belt tension should be corrected
following the ‘adjusting belt tension’ procedure.
Adjusting belt tension
Using two 24 mm spanners, unlock the two locking nuts from
above the adjustment block on the engagement handle by
turning the top nut anti clockwise and the bottom nut
clockwise. Then move both locking nuts upward along the
thread.
From the fully disengaged position, gently turn the
engagement handle clockwise until you feel it start to resist.
From this position, turn the engagement handle one full
revolution clockwise. This is the recommended tension for the
belt drive when in the fully engaged position.

Using two 24 mm spanners, screw the two M16 adjustment
nuts downwards until they touch the adjustment block. Then
turn the top nut clockwise and the bottom nut anti clockwise
simultaneously to lock the nuts in place.
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.
If a belt change is necessary, follow these steps
Using a 6 mm Allen key, unbolt and remove the pulley
guard (4xM8 cap screws).
Note: Engine not shown in this view.
Using a 16 mm and 17 mm spanner, unbolt and remove
the engine (4xM10 Nuts).
Note: loosen the belt tensioner to allow room for removal.

Remove the old belts and replace (2 x B34 vee belts).
Note: The belts pass in between the idler wheel and belt
guide on the tensioner arm.
Place engine back in place and ensure the pulleys are in
line.
Fully tighten the four bolts holding the engine to the
chassis. Check the pulleys are still in line by placing a
straight-edge across the top and bottom front pulley. If
they are not in line, loosen the four bolts holding the
engine in to the chassis and then repeat this step.
Ensure belts are properly tensioned (follow the ‘Adjusting
belt tension’ process on page 16). Fasten the pulley guard
back into place.
Note: Engine not shown in this view.
Note that after replacing a belt, the tension of the new belt will quickly change as the belt initially wears into the pulley system.
Recheck the belt tension after two hours of operation after belt replacement.
