SCIONON Grafting Shears SGS1-13
Maintenance & Adjustments
SGS1-13
The SGS1-13 is especially suited to preparing material between 3mm to 13mm in diameter and will
normally operate well in this diameter range, without the need for adjustments to be made. The step
plate and pin plates allow different diameters to be placed at different points along the jaw and cut
accordingly, as desired.
The following cuts are possible: cleft (blunt & pointed), rind (splice), wedge, whip & tongue and chip
and 'T' buds when using SCIONON Grafting Shears. Please refer to the operator's manual for details
about how each cut is made.
This model requires little adjustment other than periodically releasing the step plate rest to clean and
remove debris, and a daily clean after use.
To do this, use the 2mm hex key to release the screws holding the step plate rest in place. Slip the key
or the adjustment wrench between the step plate and anvil to remove the bulk of the debris. It is not
necessary to fully remove the screws to clear the trapped debris. The pointed end of the wrench can
also be used to remove trapped debris from between the pin plate and the jaw anvil recess. At times it
will be necessary to remove the pin plate to thoroughly clean it and the jaws.
To thoroughly clean, completely remove the screws and spacer washers. Release the screw that holds
the pin plate in place and spray a sap removal agent onto the blades and jaw. Leave to work for a few
minutes and scrub off with a nylon bristle brush or a toothbrush etc. Wash with water, dry and
reassemble. Do not over tighten the screws. Replace any screws with worn socket heads at this time.
Tip! WD40 will assist to break down sap residue and also helps to prevent surface rust from forming
on the blades when storing the tool during periods of non-use.
If the graft wood you are cutting is smaller than 8mm in diameter, only one spacer washer between
the anvil and step plate rest is required. If the wood diameter is predominantly less than 10mm,
normally no adjustments are necessary.
If the wood being cut is predominantly greater than 12mm, two spacer washers can be used to
increase the gap between the anvil and step plate rest. This helps with grip when working with the
larger diameters, especially if they are bigger than 13mm in diameter. Spare screws and washers are
attached and supplied with each new tool. These are also easily obtained at specialist hardware
stores. The thread is M3.
NB: Don't allow excessive play to develop between the jaws. Re-tension the locking nut to increase or
decrease tension as required, and periodically apply a few drops of oil to the jaw bolt and bush.
