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 machine is towed in accordance with local trailer transport regulations

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.

Hansa C40 O&M Manual –OM-013 Revision E 23/10/19

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

5 –High coolant temperature

6 –Low fuel indicator

Hansa C40 O&M Manual –OM-013 Revision E 23/10/19

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.

Safe setup procedures

Ensure all pre-operation checks have been done

Setup the work site so there is no danger to traffic or public and provide adequate warnings

Ensure the chipper is positioned on firm level ground

Ensure the feed control bar is in the neutral position when starting the chipper

Ensure the inlet table is clear of material when starting the chipper

Ensure the throttle control lever is the initially in the idle position when starting the chipper

Ensure 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 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

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

Hansa C40 O&M Manual –OM-013 Revision E 23/10/19

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:

Rotor pin

Feed roller motor

Swing arm

Hansa C40 O&M Manual –OM-013 Revision E 23/10/19

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).
