Always operate the track controls carefully and gently.
Be aware that the stump grinder is a powerful machine and moves with considerable force.
13
TRANSPORTING THE MACHINE.
The stump grinder can be transported to site either on a trailer or on a low bed truck.
MOVING MOUNTED ON A TRAILER.
WARNING
When manoeuvring by hand always use the jockey wheel. Do not attempt to support the weight of the draw bar yourself.
If moving the trailer and stump grinder off of the vehicle draw-bar, ensure the hand brake is on and
(if fitted) the rear jack stand is in the down position and the trailer wheels are chocked prior to attempting to move the stump grinder from the trailer.
If working on a gradient always ensure trailer wheels are adequately chocked. Failure to do so may result in the over centre brakes de-activating and allowing the trailer to roll. Turn the trailer to an appropriate position and chock both wheels.
Do not move the trailer with the stump grinder engine running.
LOADING THE MACHINE.
WARNING
Always perform the machine loading and unloading operation with the low bed truck parked on a solid and level surface.
Remember to use a purpose designed ramp or a loading platform for loading and unloading the stump grinder. The ramp must be strong enough to support the weight of the machine. Make sure the slope of the ramp is less than 20°.
Before loading the machine be sure to thoroughly clean the ramp and the bed. Ramps or beds that are dirty with oil, mud or ice are slippery and dangerous.
SLOPES - under 20
º
WARNING
Avoid steering when going up or down the ramps since this can be extremely dangerous. If it is absolutely necessary to steer, first drive the machine back down to the ground and off the ramps or back onto the vehicle / trailer bed and then change the direction of travel and start back up or down the ramp again.
Never operate any control levers except for the drive control levers when going up or down a ramp. Actuating other levers can cause the machine to become unbalanced and tip over.
The machine will pivot on its tracks with a see-saw type action as it is driven over the point where the ramp meets the trailer / vehicle bed. Be careful when going over this point. Drive slowly on ramps.
Always ascend and desend steep slopes with cutter wheel up hill.
It is not reccomended to work on slopes more than 20
º
STRAPS & CHAINS
WARNING
Fasten retention chains, straps or cables to the machine chassis. Do not put chains, straps or cables over or against hydraulic hoses. Make sure that chains , straps or cables do not cause damage to rubber tracks.
Fasten each corner of the machine and fasten the front arm to the trailer / vehicle bed with a
chain / strap or a suitable anchor.

OPERATION INSTRUCTIONS.
BEFORE STARTING ENGINE.
Ensure that you have read and understood this manual.
CAUTION
Check engine oil level. Top up if necessary.
Check diesel.
Check hydraulic oil level.
Visually check around the machine for fuel, oil, & hydraulic oil leaks.
Ensure the engine cover, cutter guard chains and rear access cover are in place and tightened securely.
Inspect the cutter wheel to ensure no foreign objects or dangerous matter are trapped in the cutters and that the cutter retention bolts are tight and that the cutters are in generally good condition.
Ensure that the cutter wheel bolts are fitted and tight.
Ensure that cutter wheel is not touching or is obstructed by anything and that there are no operators, personnel, members of the public or animals in close proximity to the machine.
Observe the condition of the terrain / surface under the machine and on which you (the operator)
are standing and make sure that you are confident that you are going to be able to maintain full control of the machine on this terrain / surface.
STARTING THE ENGINE.
Ensure red emergency stop button is out. Twist cutter mode button to start mode. Turn ignition key one position clockwise. Wait till lights stop flashing. This is the preheat mode and will vary depending on ambient temperatures.
Then turn further to engage starter motor. Once the engine starts, let go of the key to allow it to spring back into its normal running position. See Engine Manual for further information.
15
USE OF RUBBER TRACKS
CAUTION
Avoid manoeuvring on hard, stony and uneven surfaces such as rock, gravel, etc.
Avoid keeping the rubber tracks in direct sunlight for more than 3 months.
Avoid excessive steering manoeuvres on asphalt and concrete surfaces since these cause excess pad wear. Avoid driving on asphalt surfaces when their temperature exceeds 60°C since this causes both excess pad wear and damage to the asphalt surface.
Manoeuvres with a loose track on an irregular surface can cause the pad to detach and /or damage to the rubber track.
Rubber tracks are designed only for use on soft terrain, not for hard and abrasive surfaces such as sand, stone, minerals, etc. Use of rubber tracks on these surfaces can cause premature wear and deformation hence reducing the useful life of the tracks.
Avoid contact between sharp concrete edges etc. and the rubber track.
Fuels or synthetic oils must never come in contact with the rubber track. If this does happen then they must immediately be cleaned.
Avoid using rubber tracks in marine and seaside environments since saline air or salt in general corrode adhesion between rubber and metal inner core.
OPERATING INSTRUCTIONS. (If radio control, refer to the next section for controls)
Do not use or attempt to start the stump grinder without the cutter guards, engine covers and access covers securely in place. Failure to do so may result in personal injury or loss of life.
Start the stump grinder following the correct starting procedure. Check that the engine is running smoothly.
If it is not stop and investigate.
Once the engine is warm and you are ready to start driving.
Pull the cutter lift lever backwards to ensure that the cutter arm is at its highest position.
Use the track control levers at the rear of the machine to drive the stump grinder in the desired direction.
1. Right track
2. Left track

Use the cutter slew lever to slew the cutter to the left or the right so that it is clear of, and to the side of, the stump.
Pushing the lever forwards will slew the cutter to the left.
Pulling the lever backwards will slew the cutter to the right.
Use the cutter lift / lower lever to lower the cutter down until it is just below the level of the top edge of the tree stump ready for the first cut. ensure that the cutter wheel is to the side of, and clear of the stump.
Pulling the lever backwards will raise the cutter.
Pushing the lever forwards will lower the cutter.
The possible depth of cut will vary based on the type of tree stump and its condition. I ie. hardwood or softwood, wet or dry, fresh cut or old and decayed. It is recommended that the first cut is considered a test cut and as such the depth of this cut should be kept to a minimum, i.e less than 25mm (less than 1”). Based on the performance of the first cut the depth of the next cut can be increased or reduced. Maximum depth of cut is 65mm. (2.5”) See Figure 1 on page 16 for the start position.
17
Make sure the control panel is locked in place. All guards and screens fitted to the machine must be in place and intact.

15 16 17 18
Repeat this until the desired depth is achieved. Then lift the arm to a height above the stump, inch forward using the track levers and start the whole process again.
18
Careful attention should be paid when cutting at ground level to avoid the cutter making contact with large stones or solid objects that may be unearthed by the grinding process. When such objects are identified the cutting /grinding process should be stopped, the machine switched off with the ignition key removed and the objects removed from the cutting area before the cutting
/ grinding process is restarted.
To stop the cutter wheel rotating reduce the engine speed and turn the cutter selection switch counter clockwise.
Position the machine at the front of the stump and remove material to the depth required before moving forward.
Use only the lower front part of the wheel to cut the stump
EMERGENCY STOPPING
Push the RED STOP button. Turn off ignition key.
To release the emergency stop button, twist counter clockwise.
BLOCKAGES.
It is possible that foreign matter such as hard soil, clay, stones or pieces of timber may become trapped between the cutter wheel and its cowl either slowing or stopping the cutter. This will be accompanied by the engine starting to labour and excessive noise from the hydraulic system. If this happens proceed as follows:
Stop the cutter wheel by turning the cutter selection switch.
Stop the engine, remove ignition keys. Ensure cutter wheel has stopped turning.
Carefully try to rotate the cutter wheel backwards by hand to release the trapped object.
Remove any objects trapped between the cutting teeth and /or trapped inside the cutter cowl.
Thoroughly inspect the cutter wheel and make sure that there is no damage to any of the cutting teeth and that all cutting teeth retention bolts are tight and secure. Replace any damaged cutting teeth.
Restart engine and proceed carefully with grinding operation.
19
Radio Control (option)
Unauthorized tampering with the radio control system automatically invalidates warranty
The radio control unit is highly sophisticated and offers fine control to the movements of the machine. Fine tuning of the controls can be made only by a qualified technician or under his instruction.
The manoeuvre levers give fully proportional operation and are sprung loaded to return to zero position, i.e. "dead-man's-handle". When the manoeuvre levers are moved from zero position the respective hydraulic function starts to operate slowly and increases in speed as the lever is moved further from zero position and vice versa as the lever is moved back towards zero position.
For safety reasons all manoeuvre levers must be in their zero/neutral positions for a start-up to be made. If any lever is not in its zero/neutral position during start-up, the control unit will blink and beep the same number of times as the number of the lever to indicate which manoeuvre lever is faulty. The control unit can be used but the faulty lever will be locked and disengaged. (eg. if it beeps and blinks five times, it is the 5th lever from the LEFT which is faulty or giving the problem signal).
The micro speed button (5) slows down all the movements. This return sprung switch can be used to reduce the operating speed.
With impulses from the sprung loaded toggle switch to the left,
towards ON ( tortoise)
, reduces speed. Movement of the switch to the right,
towards OFF (hare)
, will produce 100% movement once again. Green LED : Flashing - speed reduction. Not flashing - normal speed .
The large red emergency stop button (7) turns off the radio control unit when pushed in. It also stops the cutter wheel. IT DOES NOT STOP THE ENGINE ON THE MACHINE.
The main emergency stop switch is located on the machine.
Twist the switch (7) clockwise until it springs out, then
push the On button (9) to turn the unit on. The red LED light (8)will show that the unit is on.

BATTERY CHARGER AND BATTERY CHARGING.
There are two chargers available with the machine. One is located inside the control cabinet.
The other option is 240V. The battery pack is rechargeable and of Nickel Cadmium (NiCd) type. The normal charging time for an empty uncharged battery, is approximately 12-14 hours. The battery charger is constructed so that no damage will occur from long continuous charging. The batteries effective operation time is about 8 hours on one charge.
When the battery is approaching time for charging, the control unit beeps three ( 3 ) times as a warning and at the same time the LED starts to blink on the control unit. The battery must be used until the LED goes out, after which it can be changed. If the battery capacity is too
LOW the control unit cannot be activated.
In order to reduce battery loading and for safety reasons, the control unit is turned off automatically, after the unit has been idle for more than approximately five minutes.

GREASING CUTTER WHEEL BEARING.
There is a grease nipple provided on the outside of the cutter wheel hub next to the hydraulic motor. Apply two shots of grease from a standard grease gun.
BLUNT TEETH
CAUTION
Using the stump grinder with blunt cutters will over stress the cutter wheel and cause the cutter wheel bearings to fail prematurely.
The cutter wheel bearings are a serviceable part and should be replaced on a regular basis.
It is recommend the bearings are changed yearly for optimum performance.
If the bearings start to make a rumbling noise or a high pitched whine expert advice should be sought as this could be the first signs of bearing failure.
ELECTRICAL.
NOTE
There is a main fuse located in the control box near the emergency stop button. This controls the main 12 V dc supply to the complete electrical system.
Failure of the fuse is indicative of a fault in the electrical system and the machine should be returned to the dealer from whom the machine was purchased or to Arborplant Ltd so that the cause of the fault can be found and safely rectified.

Maintenance Of Your Multi-Tip System
Congratulations for purchasing your
Multi-Tip stump grinding cutting system.
Please look after this system as set out below to insure a long and trouble free life span of the wheel and the components.
Safety is paramount. Please take note of all the enclosed recommendations and safety notes overleaf.
1.
Remove bolt and tap behind tooth with a small hammer. Avoid hitting tips.
Use safety goggles.
Tip
-
The leading teeth that are furthest from the centre of the wheel do most of the cutting.
By changing these as soon as they become blunt, you can re-use them in non-leading positions.
2.
The keeper plate and tooth can be separated once out of the slot.
Check the groove in the top of the keeper plate and the edges underneath that locate with the tooth. If these are damaged, replace.
28
3.
Check the condition of the slot.
If it is badly worn, change wheel.
4.
Check threads in Insert and on Bolt.
If damaged, replace. If re-using, make sure they are clean and free from dirt.
The bolt can be re-used up to five times before it needs replacing, providing it isn’t damaged.
Only use bolts supplied by Multi-Tip.
Threaded Insert
Nylok Bolt
Keeper Block
MultiTip Tooth
5.
Check condition of keeper plate.
If badly worn or damaged, replace.
Replace tooth with new.
6.
Make sure all surfaces are clean and free from dirt. Re-fit the threaded insert, then the new tooth and keeper block together.
Tap the front of the keeper block until it is located. Insert the bolt and wind up to a torque setting of 55Nm (40 ft-lb)
After ten minutes of use stop and check bolt tightness.

MAINTENANCE OF TRACKED UNDERCARRIAGE
RUBBER TRACK TENSION
When the tracked undercarriage is lifted the rubber track must sag 10-15 mm.
When tension decreases it must be re-tightened to prevent the track from coming off.
Do not over tighten. If you continue to pump grease into the cylinder once the track is already tight, you will compress the cylinder spring and cause excessive damage.
CORRECT INSPECTION AND MAINTENANCE PROCEDURES.
Always perform maintenance on a solid and level surface.
Never grease or lubricate or perform maintenance on the machine while it is in motion.
Solidly support the undercarriage if it needs to be lifted up for maintenance.
Use great care when maintaining the hydraulic system since oil is very hot when the machine has just finished working.
Circuits are under high pressures even when the machine is not working.
Keep all components properly installed and in good condition.
Immediately repair all damage and replace worn or broken parts.
Remove any build-ups of grease, oil or debris.
Check for oil leaks and /or damaged hydraulic hoses.
Use recommended lubricants. Do not mix different brands of lubricants.
Use only original spare parts.
Keep undercarriage widening cylinder and track-stretcher grease nipples clean.
Intervals for periodic maintenance are indicated for normal work conditions. If the tracked undercarriage is used in severe work conditions then maintenance must be performed at shorter intervals.
Dispose of lubricants in an ecologically safe way. Thoughtless disposal of lubricants can damage the environment. Become familiar with local anti-pollution laws and regulations before disposing of lubricants.
Use suitable containers when draining lubricants. Do not use beverage or food containers that might tempt someone to drink from them. Never pour lubricants on the ground or in a canal, pond or watercourse. Comply with current environmental protection regulations when disposing of lubricants.
IMPORTANT
GEAR OIL
Avoid using oils with different characteristics and brands
CHOICE OF TYPE OF REDUCTION UNIT OIL
We recommend, for reduction units, using gear oils with E.P. additives and viscosity class according to ISO VG 150 or SAE 80W/90.
When temperature variation ranges are very high we recommend using synthetic oils with E.P. properties and minimum 165 viscosity index and viscosity class VG

TRACK LOOSENING / TIGHTENING PROCEDURES.
The grease contained in the hydraulic track is pressurized. Never loosen grease valve (74) for more than one turn. If the valve is loosened too much you risk expelling grease under pressure and possible serious injury to the machine operator. Also never loosen grease nipple (73).
Remove gravel or mud from between the sprocket and the track.
Remove the screws and take off cover (68) to access the adjustment system.
To loosen the track turn valve (74) counter-clockwise no more than one turn. One turn of valve
(74) is sufficient for loosening the track.
If grease does not start to drain out then slowly rotate the track.
73 74 68
Tighten the valve (74) by turning clockwise till tight. Clean all traces of extruded grease.
To tighten the track connect a grease gun to grease nipple
(73) and pump grease until the track tightens so that there is 10-15 mm of sag. Then stop
FRONT IDLER LOCKING
DANGER
It is not normal for the track to remain tight after turning valve 1 counter-clockwise or for it to remain loose after introducing grease into grease nipple 2. Never try to remove the tracks or disassemble the track-stretching cylinder since pressure of the grease inside the track is extremely dangerous.
33
REMOVING THE RUBBER TRACK.
WARNING
Stop your machine on a solid and level surface. Jack up side of machine under main frame and support it in safe condition.
Remove the cover plate 68) on side of track frame that gives access to the adjustment system.
To loosen a track slowly unscrew valve (74) counter-clockwise for no more than one turn. One turn of valve (74) is sufficient for loosening the track.
If grease does not start to drain out then slowly rotate the track.
Insert 3 steel tubes in the space between the rollers and the tracks. Rotate the driving gear in reverse so that the steel tubes proceed with the track and contract the front idler wheel.
Exercise force sideways to slide the track and lift it off the front idler wheel.
INSTALLING THE RUBBER TRACK.
WARNING
Make sure that you are always in safe conditions with the machine lifted before performing the track installation operation.
Mesh the track links in the sprocket and place the other end of the track on the front idler wheel.
Rotate the driving gear in reverse slowly and push the track soles into the frame
Position the track using a steel tube and turn the driving gear again.
Make sure the track links mesh correctly with the sprocket and with the front idler wheel.
Adjust track tension as set out previously. Replace cover and lower back onto the ground.
UNDERCARRIAGE GREASE POINTS
IMPORTANT
Perform this maintenance procedure every 100 work hours, using lithium grease with EP2 consistency.
Clean grease nipples before connecting them to the grease gun.
Clean all grease that exits out after greasing.
Lubrication should be at more frequent intervals if the tracked undercarriage is used in particularly severe operating conditions.
Grease points for the tracked undercarriage widening cylinder pins can be found when tracks
are extended out. Grease more regularly if working in dusty or wet conditions.
34
METAL CORE
SPROCKET HOLE
CURVED PROFILE
The structure of the rubber track is shown above. The steel cables and metal core are embedded in the rubber. The carved profiles function gives stability on soft terrain. The wheel guides, located on the inside of the track, preventing the track from sliding off the guide rollers.
BREAKAGE OF STEEL CABLES.
CAUTION
Excess track tension can cause steel cables to break in the following conditions:
When stones or foreign matter accumulate between the track and the undercarriage frame.
When the track slips off its guide system.
In case of great friction such as rapid changes in direction.
BREAKAGE OF METAL CORES.
Excess track tension can cause the metal cores to bend or break just like the steel cables as stated above.
Other causes include:
Improper contact between track and sprocket.
Rotation of internal rollers.
Operation on sandy terrain.
MAINTENANCE OF DRIVE GEARED MOTORS.
CHECKING THE OIL LEVEL IN THE REDUCTION UNIT.
Stop the hydraulic geared motor with plugs (62 & 63) aligned horizontal. Remove the plugs and check that the oil level is up to their holes. Top up as necessary, filling through one of the holes and Using the other to check the oil level.
REPLACEMENT OF OIL IN THE GEARBOX.
Replace the oil after the first 100 operating hours and then at subsequent 1000 hour I ntervals. Proceed as follows to perform the replacement: - stop the reduction unit with the plugs
(62 & 63) aligned vertically with (62) at the bottom - remove both plugs and drain out all the oil; - now position the plugs horizontally and fill the reduction unit through one hole, using the other to check the oil level.
