Description
Yato blades for cordless pruning shears 40 mm are a two-blade replacement set for Yato 18V cordless pruning shears with a cutting capacity of 40 mm: the set contains a moving upper blade and a fixed lower blade. The blades are made of hardened SK5 carbon steel, and their thickness is 5.5 mm.
The blade pair fits models YT-828383 (body) and YT-828382 (set with battery and charger). The blade shape is rounded, the same as the original blades of these pruning shears.
Replacing the blade pair restores the original sharpness and cutting accuracy of the pruning shears when the original blades are worn, chipped or bent. The replacement is done from under the top cover according to the pruning shears’ instruction manual: the cover is fixed with two cross-head screws and the blade assembly with a bolt, washer, nut and locking ring.
Regular lubrication and correct tightening of the blades extend their service life. The same blade pair does not fit the 30 mm models, which have their own replacement set YT-8283811. The packaging is a hanging blister with the blades visible.
Uses and suitability:
The Yato blades for cordless pruning shears 40 mm are intended for replacing worn or damaged blades in Yato 40 mm cordless pruning shears.
- Service replacement: when the cut quality deteriorates or a blade chips, the whole blade pair is replaced at once, so the upper and lower blades wear evenly.
- Spare blade pair: in heavy use, a spare pair keeps the pruning shears in use when a worn, chipped or bent blade has to be replaced.
- Compatible tools: YT-828383 and YT-828382. The manufacturer states only these two models as compatible, so the blade pair is not intended for other pruning shears in the range, such as the Yato cordless pruning shears 18V, body only.

Instructions for using the Yato blades for cordless pruning shears 40 mm:
Preparation: remove the battery from the pruning shears and put on protective gloves. Undo the two cross-head screws of the top cover with a cross-head screwdriver and lift the cover off.
Removing the old blades: remove the bolt (a), washer (b), nut (c) and locking ring (d) in this order. Tap the blade assembly loose carefully with a wooden dowel and remove the worn blade (e). Clean the drive gear (f) if necessary without chemicals.
Fitting the new blades: place the new upper and lower blades in position and reassemble the parts in reverse order. The flat surface of the locking ring (d) must meet the flat surface of the shaft. Do not overtighten the nut: there must be no sideways play between the blades, but the blades must move easily.
Finishing: drip 2–3 drops of machine oil into the lubrication hole, fit the top cover, insert the battery and run a few empty cutting cycles. Check the blade tension before the first cut.
Warnings:
- Risk of cuts: the blades are sharp: handle only wearing protective gloves.
- Battery out: replace the blade only with the battery removed from the pruning shears.
- Compatible models only: YT-828383 and YT-828382; a blade fitted to the wrong model can damage the mechanism.
- Correct tension: a nut that is too tight or too loose wears the gear and causes a gap between the blades.
- Not for children: keep the blades in their packaging out of the reach of children.
