VEHICLE / TRACTOR PREPARATION

We recommend vehicles are fitted with cabs using ‘safety glass’ windows and protective guarding when used with our machines. Fit Operator Guard (See drawing) using the hooks provided. Shape the mesh to cover all vulnerable areas. The driver must be looking through mesh and/or polycarbonate glazing when viewing the working tool in any working position - unless the vehicle/ cab manufacturer can demonstrate that the penetration resistance is equivalent to, or higher than, that provided by mesh/polycarbonate glazing. If the tractor has a roll bar only, a frame must be made to carry both mesh and polycarbonate glazing. The operator should also use personal protective equipment to reduce the risk of serious injury such as; eye protection (mesh visor to EN1731 or safety glasses to EN166), hearing protection to EN352, safety helmet to EN297, gloves and high visibility clothing.

Vehicle Ballast

It is imperative when attaching ‘third-party’ equipment to a vehicle that the maximum possible stability of the machine and vehicle combination is achieved – this can be accomplished by the utilisation of ‘ballast’ in order to counter-balance the additional equipment added. RC 162 has been tested on the following Arm systems: Spearhead Twiga MID, PRO & Flex with tractors from 4400 kg, wheelbase of 250 cm and a track width of 200 cm measured from / to the outer edge of the tire till tractors of 5500 kg , wheelbase of 280 cm and a track width of 250 cm measured from / to the outer edge of the tire. Because there are different types of tractor structures and differences in weight distribution you must view this as a "guideline". Is it possible, then choose wide tires as possible to increase the stability of the vehicle.

Front weights

May be required for rear mounted machines to place 15% of total outfit weight on the front axle for stable transport on the road and to reduce ‘crabbing’ due to the drag of the cutting unit when working on the ground.

Rear weights

May be required to maintain a reasonable amount of rear axle load on the Opposite wheel from the arms when in work; for normal off-ground work i.e. hedge cutting this should be 20% of rear axle weight or more for adequate control, and for ground work i.e. verge mowing with experienced operators, this can be reduced to 10%. All factors must be addressed in order to match the type and nature of the equipment added to the circumstances under which it will be used – in the instance of Power Arm hedge cutters it must be remembered that the machines centre of gravity during work will be constantly moving and will differ from that during transport mode, therefore balance becomes critical.

Page 12

12 Hedge Cutter RC 162

Factors that affect stability

➢ Centre of gravity of the tractor/machine combination. ➢ Geometric conditions, e.g. position of the cutting head and ballast. ➢ Weight, track width and wheelbase of the tractor. ➢ Acceleration, braking, turning and the relative position of the cutting head during

these operations.

➢ Ground conditions, e.g. slope, grip, load capability of the soil/surface. ➢ Rigidity of implement mounting.

Suggestions to increase stability

➢ Increasing rear wheel track; a vehicle with a wider wheel track is more stable. ➢ Ballasting the wheel; it is preferable to use external weights but liquid can be

added to around 75% of the tyre volume – water with anti-freeze or the heavier Calcium Chloride alternative can be used.

➢ Addition of weights – care should be taken in selecting the location of the

weights to ensure they are added to a position that offers the greatest advantage.

➢ Front axle locking (check with tractor manufacturer).

NOTE: The advice above is offered as a guide for stability only and is not a guide to vehicle strength. It is recommended that you consult your vehicle manufacturer or local dealer to obtain specific advice on this subject, additionally advice should be sought from a tyre specialist with regard to tyre pressures and ratings suitable for the type and nature of the machine you intend to fit.

Operators need to be competent and fully capable of operating this machine in a safe and efficient way prior to attempting to use it in any public place. We advise therefore that the prospective operator make use of relevant training courses available such as those run by the Agricultural Training Board, Agricultural Colleges, Dealers and Spearhead.

Working in Public Places

When working in public places such as roadsides, consideration should be paid to others in the vicinity. Stop the machine immediately when pedestrians, cyclists and horse riders etc. pass. Restart only when they are at a distance that causes no risk to their safety.

Warning Signs

It is advisable that any working area be covered by suitable warning signs and statutory in public places. Signs should be highly visible and well placed in order to give clear advanced warning of the hazard. Contact the Department of Transport or your Local Highways Authority to obtain detailed information on this subject. The latter should be contacted prior to working on the public highway advising them of the time and location of the intended work asking what is required by way of signs and procedure. – ‘Non-authorised placement of road signs may

create offences under the Highways Act’.

Suggested Warning Signs Required

‘Road works ahead’ warning sign with a supplementary ‘Hedge cutting’ plate. ‘For 1 km’ or appropriate shorter distance may be added to the plate.‘Road narrows’ warning signs with supplementary ‘Single file traffic’ plate. White on blue ‘Keep left’ (*) arrow sign on rear of machine.

* Note – this applies to EU Market machines where traffic passes to the left of a machine working in the same direction as the traffic flow. The direction, use and colour of the arrow sign will depend on the country of use and the Local Highway Authorities regulations in the locality.

Use of Warning Signs

▲ On two-way roads one set of signs is needed facing traffic in each direction.

▲ Work should be within 1 km of the signs. ▲ Work only when visibility is good and at times of low risk e.g.: NOT during ‘rush-hour’. ▲ Vehicles should have an amber-flashing beacon. ▲ Ideally, vehicles should be conspicuously coloured. ▲ Debris should be removed from the road and path as soon as practicable, and at regular

inter vals, wearing high visibility clothing and before removing the hazard warning signs. ▲ Collect all road signs promptly when the job is completed.

BEFORE STARTING WORK:

Description of the RC 162 Hedge Cutter:

Hydraulic driven hedge cutter. The tool is used for hedges and smaller branches and bushes, that have a maximum diameter of 40 mm without fraying the branches. The machine consists of a selfsupporting shield with 3 shafts for mounting rotors with 6 tempered knives. Each shaft is driven by ridged belts and the overall working is through the hydraulic driven vehicle. The branch raiser is situated beneath the lower rotor. The hedge cutter is supplied with an adapter for mounting on various vehicles. The belt drive is fully covered by a safety steel cover. Gaining access to the belt drive for maintenance purposes requires loosening 2 bolts.

Setting up for work:

• Wear safety glasses and work gloves.

• Remove transport safeguard if fitted and turn the armsystem into workposition.

• Start the tool at low oil flow (low rpm). Let the tool warm up for a few minutes.

• Adjust the RC 162 horizontal or vertical for hedge cutting and raise into work

position.

• Adjust the rotor rotations to the recommended speed and drive with a safe speed that is adjusted to the terrain and other possible obstacles.

Tool start:

• Choose low engine rpm.

• Make sure that the surrounding is secured.

• Warm start – Start the tool.

• Cold start – never start the tool at maximum rpm. Let the tool run without too

much strain for approx.. 15 minutes to heat up the oil.

• Slowly increase rpm until the correct oil amount is reached.

• Never attempt to restart a strained/wedged in tool. Stop the tool and the vehicle

engine. Remove the ignition key and engage the handbreak. Only then it is safe to remove the wedged in material. Always wear safety glasses and work gloves.

Tool stop:

• Reduce engine rpm to fast idling and stop the tool.

• Never increase or reduce the oil amount too fast. This will damage the hydraulic

system on a long-term basis.

• When you are finished working, stop the engine, remove the ignition key and

engage the handbreak. Always wear safety glasses and work gloves. Refit safeguard. Beware of sharp cutting parts!

• Always show consideration for other road users during transportation.

Power lines:

Always pay close attention to overhead lines. Between power poles there is always a risk of hitting overhead lines. When in doubt please contact your local power station for advice concerning safety distance.

Page 21

Hedge Cutter RC 162 21

Never use the tool on an unstable or non suitable vehicle

Mounting to an arm system or similar: Tools can be mounted to the arm system with a Quickshift or

with bolts. GreenTec RC 162 is specially designed for the Spearhead

arm system program. RC 162 is a tool designed to be mounted on tractors via a

suitable armsystem. The RC 162 has a work width of approximately 160 cm. Total

wieght of the unit is150 kg. If necessary, ballast can be mounted on the vehicle or the arm system to ensure stability and balance during any work or working conditions.

Be careful with rotating knives. Danger of cuts! Danger of getting caught!

MOUNTING / DISMOUNTING RC 162:

Mounting the tool must be done at a plane and safe surface. Always pay close attention when mounting the tool to the machine; make sure that no persons are within range of the saw/blades, as these can cause injuries even when stationary. For safety reasons the saw/blade must always be fitted with the safety caps, and these should only be removed when starting the work. Always wear work glowes.

Never use the machine with broken or missing knives

The tool must never be operated without the rubber curtain.

In general:

• After finishing work, the arm with the tool is pulled close to the vehicle.

• The tool is positioned where it takes up less room.

• The inner arm is lifted until transportation stop or close to the roof of the vehicle.

• Transport safety lock is mounted if supplied.

• The unit is now ready for transportation.

Transport position shown on aSpearhead Twiga

Page 25

Hedge Cutter RC 162 25

Work position with RC 162:

1. Turn the arm into work position.

2. Adjust the cutting angle for the first cut. Always start from the bottom vertically or in a suitable angle. Choose the most suitable forward drive depending on the condition of the hedge, surface, traffic and visibility.

3. Adjust the angle for the second cut. Keep the same angle as for the first cut.

Page 26

26 Hedge Cutter RC 162

4. If needed finish off with a horizontal cut. If the hedge is wider than the tool you get the best result by starting the cut close to the vehicle.

5. RC 162 is NOT constructed for lawn mowing.

6. NEVER turn the tool towards the tractor. This is very dangerous.

Page 27

Hedge Cutter RC 162 27

Never use the machine without fitting the belt cover.

Extreme caution must be shown when knives, rotors and/or drive belt are cleaned; these areas have a lot of sharp edges. Always wear work gloves and safety glasses, and if possible, always use a tool to remove unwanted material to avoid direct finger or hand contact.

Never use the machine for cutting grass.

Never use the machine with defective knives, bushes or bolts. If rubber cover is defective it must be changed immediately.

Never use the machine for anything else than decribed in this manual.

Never use the machine as crane or lift.

FIELD OF APPLICATION:

Intended use: RC 162: Used for hedges and smaller branches and trees. Branches must not exceed

40 mm in diameter to avoid fraying. Starting and stopping the tool must always be done at the lowest rpm or lowest oil flow.

The saw and the hedge cutter is solely built for use in landscaping or the like. Vertical cuts are allowed at an angle of no more than -150. Horizontal cuts are possible on hedges no more than 150 cm. wide and with branches with a thickness up to 40 mm. larger branches will stop the tool.

It is recommended that the forward speed is kept at a minimum when starting the work to achieve the correct work speed for the tool. Adjust the angle of the cutter so that it is straight and adjust the position to make the knives cut directly at the branches. Where possible, the knives have to cut vertical in the direction of travel. This prevents the knives from bending during work. If smaller branches and other unwanted material gets stuck, the machine and the vehicle must be stopped and the ignition key removed before attempting to clean the knives. Any other use than the described is against the intended use. GreenTec A/S is not liable for damages as a result of this; the risk lies solely on the user.

Unintended use:

Under no circumstances is it allowed to use the machine for cutting down trees. The machine must never be used as a stationary sawmill or the like. The machine must not be used for sharpening poles. The machine must only be used for cutting wood material.

Inadmissible working:

The operational reliability of the delivered machine can only be guaranteed if it is used according to the intended use as described in this manual. The limit value stated in the data sheets must under no circumstances be exceeded. The machine is not suited for cutting grass. The machine must never be used for cutting the “back side” of a hedge, so that the rotating knives are facing the user.

When responsible for the machine always follow the rules below:

• Always inspect the work area before starting work and remove potentially dangerous material.

• Never use the machine close to persons or animals. Read the section ” Safety distances”.

• Make sure that all cab covers are secured and that the windows remain closed during work. If the vehicle has no cab, always wear safety glasses and earmuffs.

• Only use the machine with the correct speed of the knives.

• Never approach the machine when it is running, always shut the engine off and

stop the vehicle.

• Always remove the ignition key when leaving the driver’s seat.

• Only use the machine for the intended purpose. This machine is solely

constructed for hedge cutting. It must never be used for grass cutting or the like.

• Lower the machine and set it in a horizontal position, so that there is no access to the knives when parked or not in use.

Page 29

Hedge Cutter RC 162 29

It can be an advantage to use the ”Ear lifter” (Optional

equipment) at the bottom of the hedge cutter to lift smaller twigs closer to the knives. Caution must be taken when working close to the ground.

Smaller adjustments of the cutting angle can be done when driving but it is recommended to stop working when making larger adjustments.

To prevent the knives from blocking the lower ones are mounted to swing freely at an 3600 angle. The upper ones at

1100. A non-return valve is mounted on the hydraulic system to slow down the knives faster. If the knives block despite this, stop the cutter, stop the vehicle, remove ignition key, engage the handbrake, use safety glasses and work gloves and remove the unwanted stuck material.

When the sap disappears from the branches the end result will

become more ”frayed”. When operating off growth season the

knives will wear out faster.

DRIVING DIRECTIONS FOR HEDGE CUTTER:

Always start and stop the tool at the lowest pto rpm./ olieflow. Choose a suitable forward drive depending on the hedge, surface, traffic and visibility. We recommend that you start driving slowly, allowing the knives to reach the

recommended speed. Adjust the cutting angle to be approximately 90° against the branches. If reaching a larger branch, adjust the cutting height to meet the branch ”straight on”, lower the speed to a minimum and “plane” off the branch.

If smaller twigs or other unwanted material get stuck between the knives, stop the machine and remove it.

Where possible, the knives have to cut vertical in the direction of travel. This prevents the knives from bending during work.

Carefully check condition of all hoses during routine service paying particular attention to chafedFejl! Bogmærke er ikke defineret. outer casing.

Daily inspect all hydraulic hoses and fittings to be in good order. Any damages or leaks must be rectified immediately; this is part of the daily maintenance and is your responsibility, to unsure a long reliable working life. Hoses with damaged metal braid should be replaced.

When replacing hoses avoid twisting fitting, use two spanners to slacken and tighten

The GreenTecs hydraulic system works at very high pressure, when replacing hoses use only genuine hoses, a burst hose could be very dangerous.

Always check the black protective sleeve is in good order, to replace sleeve is far cheaper than replacing expensive hoses.

Lubrication:

After machine wash:

Lubricate all machine parts and extra equipment after each wash (if lubrications points are present) Wash never directly on bearings.

Hydraulic hoses:

Warning!

Hose is weakened when installed in twisted position. Also, pressure pulses in a twisted hose tend to fatigue wire and loosen fitting connections. Design so that the machine produces bending rather than torsion

Please read the following advice carefully!

Hose warranty is limited to replacement of hoses due to faulty materials or manufacture. Warranty will not be considered on: hoses damaged by chafing, abrasion, cuts or pinching while in work, or to damaged threads due to over tightening.

Oil Supply:

• Daily before starting up check oil level in tank reservoir.

• It is a good practice to constantly keep an eye on the tank level gauge, (this can be seen

from the tractor seat) as a pipe burst could empty the tank within minutes.

• A pump or motor starved of oil will be damaged beyond repair.

• Replace oil if signs of contamination occur (discolouration)

• Use correct and suitable hydraulic oil

• Contamination can be reduced by:

• Thoroughly cleaning around reservoir cap before removing

• Using a clean container when replenishing the system

• Regularly servicing the filtration system.

• Never allowing oil level to fall below the sight gauge .

• Daily inspect all hydraulic connections and fittings to be in good order. Any damage or

leaks must be rectified immediately; this is part of the daily maintenance and is your responsibility, to maintain a long reliable working life.

• When tightening fittings always use two spanners when necessary and do not over

tighten. If a fitting leaks it will need to be replaced

Page 39

Hedge Cutter RC 162 39

Pump and engine failure:

There can be many reason for pump and engine failure, cavitation, too high pressure and pollution.

• Never run out of oil.

• Never let a cold machine run up in speed too fast. The vehicle engine must run

idle before the tool engine is connected/disconnected.

• The speed of the vehicle engine must never be increased or decreased too fast.

• Suction hose and pump fittings must be checked and tightened on a regular basis.

• Never start or stop the rotor at max. rpm.

• Avoid sudden arm movements via the joy stick and irregularities on the ground,

as changes in pressure is directed back to the pump and may result in malfunction.

• Avoid letting the rotor hit an object such as a rock, as this will cause pressure changes.

• Never transport the machine with the engine running.

• Never choose a higher PTO rpm. / oil flow than recommended.

• Never work with more than the recommended PTO speed /Oil flow – this will

result in overheating.

NOTE: The engine guarantee is limited to replacement due to defective material or manufacturing. Cavitation, pollution and too high pressure can easily be detected by examination. The guarantee will also be void if the defect is due to misuse.

GreenTec Special tool

Special tool mounted. Loosen knife bolts.

Knives: ATTENTION! When carrying out any kind of service on or around the rotors

always pay attention to the swinging knives. Always wear safety gear, including helmet, work gloves and safety glasses.

It is possible to sharpen the knives by sharpening the cutting edges, ensuring that the knives after sharpening are the same lenght and weight. Be careful not to let the knives get too hot during sharpening as this will affect the temper. All knives are swinging freely and rotate around hardened steel bushes that are replaceable. When changing the knives it is important to always change them by the pair to maintain the balance of the rotor. Bushes must always be changed when mounting new knives.

If the knives show signs of severe wear, damages or cracks they must be replaced immediately. Never attempt to weld the knives as this will leave them brittled and extremely dangerous. Never take a risk with the knives – if in doubt, replace them.

When the sap disappears from the branches the end result will become more ”frayed”.

When operating off growth season the knives will wear out faster. The best result is gained between April and October.

Changing knives:

Recommended tools:

• GreenTec special tool (Fixed to the RC 162)

• 19 mm Ring/Fork spanner

• Work gloves

• Safety shoes

Procedure:

• Remove the ring pin from the GreenTec special tool and pull the tool out.

• Attach it in the rotor in the ”banana-shaped” hole and through the slot in the

chassis.

• Now loosen the knife bolt with the Ring/Fork spanner.

• Mount the new knife, bush, bolt and lock nut.

• The nut is tightened to correct tension 95 Nm.

Page 41

Hedge Cutter RC 162 41

WARNING!

Bushes MUST be replaced if they have

cracks or show signs of wear and tear.

NEVER compromise when it comes to

safety. When replacing knives also

change bushes, knife bolts and nuts.

Bushes and bearings:

Several main turning points have replaceable bushes or bearings. If these show signs of wear and tear they must be replaced. All bushes, bolts and bearings can be supplied from the GreenTec Spare Part Department.

Storage and lifting:

Before storage always wash the machine carefully. Remove all traces of grass and dirt.

Page 42

42 Hedge Cutter RC 162

Be careful and never use a high pressure cleaner close to the lacquer. Steam cleaning must be done with caution. Remove all traces of detergents to avoid discolouration or damage to the laquer. It is important to store the machine covered from rain or sunlight. Must be placed horizontally on a level surface or pallet.

Make sure that the machine is unable to tip or fall down when stored. Find a suitable storage place or support the machine.

Never leave hydraulic hoses on the floor. They pose a risk of stumbling. Place all hoses on the machine/tool.

Always store the machine in cleaned condition. Dirt attracts moisture and this may result in increased corrosion. Damage to laquer must be repaired.

OBS must store dry! Risk of water in bearings.

Hedge Cutter RC 162 43

Correct lift of RC 162:

GreenTec recommends that the RC 132 Hedge Cutter is stored at a suitable pallet when not in use. If it needs to be moved use a pallet lifter or forklift. Alternatively it can be lifted with an authorized rope or something similar. The RC 132 weighs 150 Kg and the rope must be authorized for this weight as a minimum, but preferably more.

After storage:

Follow the recommended maintenance advice given in this manual. Pay particular attention to the condition of the knives and belts.

Remember that the RC162 Hedge Cutter is constructed to resist even the toughest conditions and that with some care and attention it will supply you with many years of problem-free service. To avoid problems and ensure that it is covered by the guarantee, always use original spare parts and make sure that the machine is not used for anything else than described in this manual.

REMEMBER:

Regular maintenance will increase the lifespan and the resale price of the machine.

WARNING!

Before attempting to repair, maintain or adjust the machine, always make sure that the tool has stopped, the ignition key is removed, hydraulics disconnected, hand brake secured and the tool is safe on the ground.
