OPERATING INSTRUCTIONS 05 09 WARDENAAR PEAT PROFILE SAMPLER Components of the sampler and their function The small diameter tube is fitted in an inside corner of the sampler and is necessary to break the suction that occurs during extraction of the sampler from the peat see figure at page 2 At the base it is closed in a particular position and can be opened by turning the tube 180 It can also be moved upwards and downwards The top part will fit on a small bicyclepump inwhich a valve fiap is necessary to build up pressure The diagonal locking rod is used to fix the sampler in the neutral position during transportation and during thrusting the sampler into the peat and is also used to fix the sampler in the closed position when pulling the sampler out of the peat The safety box is used to protect the sampler from damaging during transportation and also to prevent injuries when the sampler is not in use The two handpins of the hinges can be removed to open the sampler after it has been extracted from the peat To open the sampler one also has to detach the lower connection see figures A B C D and E on page 4 for which safety gloves are recommended Features to reduce compaction and disturbance of the profile are a Sharp bent cutting edges b The walking in mechanism c The construction at the lower end of the sampler causing the sampler to cut a somewhat smaller volume than would strictly fit inbetween the samplerha

5. lves which allows a relatively free movement of the cut profile inside the sampler d The sampler is slightly tapering somewhat wider at the top side which again allows a relatively free movement of the cut profile inside the sampler the fact that the small tube is vertically mobile and can thus be put in a upward position during penetration into the peat The sampling spot Before sampling one should select a spot free of any sound woody tissue such as logs or roots over 2 5 3 cm in diameter that might occur in the top 50 cm of the peat by testing it with a thin steel rod as they will damage the cutting edges of the sampler To push the sampler in After determining a suitable spot to cut a profile one should do the following 1 Fix the sampler into the neutral position by the diagonal locking rod 2 Move the smali diameter tube upward 40 50 cm and be sure it is in the closed position 3 Lift the sampler high by its handle and aim vertically to the sampling spot 4 Thrust the sampler down into the peat with great soeed and force but keep control It should have cut through fhe upper 40 50 cm of the peat now in case you hit too big a root or other obstacle despite checking carefully for sound woody tissue in advance you should check the 1 M3 05 09 93 E The sampler and its components Small diameter tube in upper closed position Handle Upper hand pin Locking holes e4 0 9 Lower hand pin A Diagonal lo
6. ossible meaning that you have to start pulling without unplugging it first It might unplug by itself while pulling and also might not be plugged at all In wetter peat types the unplugging is usually easier and can be noticed by pressure drop and air bubbles coming to the surface Detach the bicycle pump To make pulling easier one could pull the sampier in different directions laterally to widen up the surrounding peat somewhat but this might not be necessary especially when a second person is available to help pulling the sampler out Pull out the sampler more comfortable by two persons slowly allowing the air to stream through the tube underneath the sampler Pulling too hard might cause breaking of the core and loosing some material It best to pull with instead of your back Lay down the sampler the removeable half which hinges with removeable handpins upward and detach the diagonal bar Push the handle into the opposite ultimate position see figure C suddenly by hitting the handie with your hand this is to loosen the upper half of the sampler from the peat core if necessary In certain materials dike humus or drier peat this loosening might be not necessary and could possibly damage the fragile base of the sampler Pull out the lower removeable handpin and put on your safety gloves Beware of cutting edges and determine on which side the sampler halves are attached by a pin and on which side they are attached by a knob
7. rom damage Never use an ordinairy hammer to cut through sound woody tissue in case further penetration is impossible use the special impact absorbing hammer art no 04 05 05 If that doesn t help and you still want to go deeper try again on another sampling spot Always use safety gloves when opening up the sampler or during other activities that might be dangerous in that respect like cleaning the sampler Information or suggestions A note has been published in the Canadian Journal of Botany 1987 65 1772 1773 In case you have or need information or suggestions about field applications or operational problems we are very interested to hear them and they can be adressed to Eijkelkamp Agrisearch Equipment 5 M3 05 09 93 E
