Hansa C4 O&M Manual - OM-005 Revision F 20/06/2019

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 50 mm diameter branches

It is helpful (but not required) to keep a wooden stick handy, approx. 50 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) or an enclosed container

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 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 all chipper components are in place and in good condition

If any parts are worn or damaged, contact Hansa for replacements

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

Always replace and securely tighten fuel cap after refuelling

Allow engine to cool down before refuelling

If you need to drain the fuel, ensure this is done outside

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. Wipe up the spilled fuel and move the chipper away from the

area of spillage before starting

Hansa C4 O&M Manual - OM-005 Revision F 20/06/2019

Safe operating procedure

Wear safety equipment: Safety glasses and hearing protection 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

Stand clear of the discharge zone, even when no material is being fed into the machine

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

DO:

DO NOT:

Hansa C4 O&M Manual - OM-005 Revision F 20/06/2019

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

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

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

Move or tilt the machine while it is running

Remove the catcher bag while the machine is running

Touch any guards or stick hands between guards while the machine is on or connected to a power supply

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

Leave the chipper on while it is unattended

Starting procedure

Before proceeding, ensure the ‘safe setup procedure’ has been followed on page 6 of this manual.

Turn the choke lever, fuel lever, and

engine switch to the “on” position.

Turn the throttle lever to the “max”

position.
