Safety regulations
1. Use caution and patiencewhen servicing the harvesterhead.
2. Immediately report anymalfunctions in the head toyour foreman or the personresponsible for servicing.
3. The engine should be shut offduring servicing.
4. Avoid working alone.Keep a mobile phone nearyou when you service theharvester outside the cab.Store an emergency alarmnumber in one of the quickselect phone numbers.
5. Service the harvesting headaccording to themanufacturer�s serviceschedule.
6. If you are not familiar with theconstruction of the machine,ask the manufacturer forinstructions before beginningto service or repair it.
7. Danger to life!Never attempt to service thehead near the range ofmovement of the saw, thedelimbing knives or the feedrollers when the engine isrunning.
Safety while servicing and repairing:
8. Danger to life!When servicing the head,make definitely sure thatnobody starts the harvester!If the harvester is started, theknives and rollers will close,the saw will return to its homeposition and the head willreturn to a horizontal position!
9. Manual control:
Each directional valve isequipped with a precontrolsolenoid which allows thedirectional valve to becontrolled manually bypressing the end spindle.
9.1 Danger to life!Avoid using the manualcontrol when troubleshootingor repairing the harvesterhead. If maual control isabsolutely necessary beextremely caution.
9.2 Do not use the manual controlto tilt the harvester head oroperate the rotator.
9.3 Be sure of the correct valve.Beware of the spinningmotionof the feed rollers and themovement of the delimbingknives and the saw bar.

Safety regulations
10. When testing the functioningof the saw:
- The harvester head mustbe in a horizontal position
- Nobody is to be in line withthe saw
- Keep the harvester headas near to the ground aspossible
11. Never raise the harvesterhead near the cab windowswhile testing the saw.
12. When servicing indoors, thesaw must only be tested withthe chain removed.
13. Remove the pressure fromthe hydraulic system beforebeginning to service or repairjobs.
14. Do not clean or lubricate themachine while the engine isrunning.
15. Always wear protective gloveswhen handling the saw chain.
16. Pay special attention tocleaning and inspecting thelimit switches, saw bar, sawchain and delimbing knives.Do not slit yourself to thecutting edge of the delimbingknives.Always wear protective gloveswhen handling the delimbingknives.
17. Be aware of the danger ofslipping when working on topof the harvester head.
18. If oil gets on your skin, re-member to clean it off. Takecare of cuts and scratchesimmediately.
19. Use safety goggles in serviceand repair jobs.
20. Do not change the pressuresettings without the approvalby the manufacturer.
21. Use only sound tools andapproved lifting equipment,abandon / repair damagedtools.
22. Danger!Be careful when removing hotliquids or oils from themachine. Hot liquid or oil cancause serious burn injuries.
23. Disposal of liquids, oil or otherproblem wastes:
- Do not pour into ground orwater
- Find out the proper ways todispose of them
- Note the local environmentalregulations

Testing the length measurement
1. Lift the harvester head so that you can rotate the measuring roller.2. Shut the engine off.3. Turn on the measurement system, switch on the power to the harvester
head by pulling the knob out on the main switch (moto-switch).4. Go to the length calibration programming mode.5. Write down the original value of the length correction.6. Set the length correction of pine to zero.7. In the Handling mode, select pine for the tree sort.8. Press the ENTER key to zero the length.9. Mark the zero point on the measuring roller and on the measuring roller
housing. Be careful not to move the roller.10. Check that the length on the display is zero.11. Rotate the measuring roller with force e.g., by kicking it.12. Rotate the measuring roller so the zero mark on the measuring roller is
inline with the zero mark on the measuring roller housing.13. Check the length on the display. It should be divisible by 50 without a
remainder. E.g., 50, 100, 150, 200, 250, 300, etc.
If the display shows some other length, the measuring system is notfunctioning correctly at high speeds.
ATTENTION!After testing, change the lengthcorrection to the original value.
Repair:
Adjust the gap between the sensor and code roller again. If this does not help,replace the sensor.

Adjustment and serviceinstructions
Diameter measuring
Before calibrating of the diameter, you should check thefollowing:
1. The tree travels in the centre of the harvester head. Ifnecessary, adjust the tree (a round one) to the centreusing the reaction brace .
2. Check that the measurements A and B are equal. Ifthe difference is greater than 5 mm, an adjustment hasto be made. A half revolution of the reaction brace isequivalent to a 5 mm change in the difference betweenmeasurements A and B. Recheck the measurements.
3. When the feeding rollers are closed, the sensorreading must be 30. If the reading is something else, itcan be adjusted by turning the sensorbody.

ABC
1. Turn the engine off and make sure no one is able to startthe machine.
2. Turn the saw bar to its upper position and remove the oldsensors.
3. Use a thin-bladed screwdriver or similat tool to check thatthe detector holes do not coincide with the sensorlocations (A, B).
4. Lightly screw the new sensors into place until they areseated.
5. Unscrew the sensors one revolution to obtain a 1 mm gap.
6. Tighten the locking nut C.

Delimbing knife sharpening
The condition of the delimbing knives has a major effect on thepruning result and pruning resistance (especially in the summer).The recommended shape of the delimbing knives is shown in thefollowing diagram. Sharpen the top side of the blade to a 45°angle. Do not sharpen the bottom side.
Saw chain lubricating pump adjustment
1. Oil volume adjustment2. Lubricating pump3. Check valve4. Lock nut
NOTE! If the adjusting screw isovertightened, the pump will notfunction, because the piston willnot be able to move.
Oil volume adjustment:
Oil volume should be adjusted according to the type of oil usedand the lubricating need. Open lock nut no. 4. Turn adjustingscrew no. 1 to obtain a suitable oil flow volume. Turning thescrew clockwise will decrease the volume. Tighten the lock nut.

Testing instructionsPulse sensor testing
1. Turn on the power by turning the switch to the ON position.
2. Switch the NPN/PNP switch to the correct position, depending on which type ofinductive sensor you are going to test. In the new harvester heads all inductivesensors are NPN type. In the older harvester heads the saw sensor is PNP type ifthe saw sensor�s diameter is 8 mm.
3. Connect the conductors as follows:- Brown conductor to +- Blue conductor to -- Black conductor to IN
NOTE! If you are going to test two sensors at the same time, connect as follows:- The brown conductors to +- The blue conductors to -- The black conductors to different IN poles.
4. Put a piece of metal in front of the sensor. If a red or yellow lamp lights on the tester,the sensor is in good condition, otherwise the sensor is faulty.
5. Turn off the power of the test device when you have finished testing the sensors.
If the BATT.OK lamp does not light when the power has been turned on, thebatteries are empty. Replace the batteries.

NOTE! The measured object hasto be without a voltage.E.g., Checking the diameter sensor:
1. Connect the wires as in the adjacent figure.
2. Slowly turn the the gear of the diametersensor and watch the display of the digitalmultimeter. The value should vary between1.5 and 11.5 kW (kilo-ohm) (±10 %)depending on the rotating direction.
By connecting black and blue wires to themultimeter, reading must be 10 kW (±10 %).Rotating of the gear wheel may not affect thereading.
Resistance measurement
Short-circuit measurement
Select the measuring unit by turning theswitch as shown in the adjacent figure.By putting both ends of the black and redmeasuring cables together you shouldhear an audible signal from the digitalmultimeter.
NOTE! The wire that you aregoing to measure has to bewithout voltage.

Diode test
When the digital multimeter is connected as shownin the adjacent figure and the switch on the digitalmultimeter is turned to the diode measuring mode,the multimeter show a value between 0.5 - 0.7.Swapping the measuring cables on the diode shouldchange the reading on the multimeter to 1.
NOTE! To check a diode, it hasto be without a voltage.
