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 130 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 18 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 inlet chute and housing are clear of any leftover material
That all labels are in good condition and easily legible
Replace damaged or unreadable warning and operating
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
Always replace and securely tighten fuel cap after refuelling
Allow engine to cool down before refuelling
Do NOT smoke when using or refuelling the chipper
Never remove fuel cap or add fuel with the engine running
Never refuel the chipper indoors
Never store the chipper or fuel container inside where there is an open flame, such as a water heater
If fuel is spilled, do not attempt to start the engine, but move the chipper away from the area of spillage before
starting
Safe operating procedure
Wear safety equipment: Safety glasses and earmuffs must be worn
at all times
Wear work gloves: Wearing work gloves is optional but highly
recommended - ensure that the gloves fit tightly
Tie long hair up
Long hair could be pulled into the chipper
Wear clothes that sit tightly
Avoid scarves and any items that can get caught in the chipper
Keep your face and body away from the inlet chute
DO:

Hansa C21 O&M Manual - OM-022 revision A 21/08/2018

8
Stand clear of the discharge zone, even when no material is being fed into the machine
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, disconnect the spark plug wire 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 (max 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
The governor controls the maximum safe operating speed and protects the engine and all moving parts from
damage caused by overspeed
DO NOT:
