The shears are a very useful tool for pruning in the garden! This operation is necessary to promote the development of the plant, to control its growth and to give it the desired shape. To do a good job, the shears must be serviced periodically!
Types of shears
Depending on the type of pruning you want to do, you will need to adopt the appropriate shear.
On the market we find:
- pruning shears are suitable for cutting thin branches and for shaping hedges and shrubs;
- pruning shears that in turn distinguish between two main types. For light pruning, by-pass pruning shears are used; the working mechanism is similar to that of scissors and exploits the contrast between two blades. For pruning dry and harder branches, shears with swing cut are preferable. The operating mechanism in this case is different: the sharp blade is the upper one, which cuts the branch that rests on the thickest and slightly flatter lower blade. This mechanism allows you to work without too much effort and ensures a precise cut of the branch.
The maintenance of the shears must be carried out about every 150 hours of use and must cover all its parts. Surface cleaning, on the other hand, must be carried out at the end of each use, to maintain their efficiency over time! The condition of the blades must also be checked. If damaged, the use of the blades may require excessive effort, which may result in damage to internal components. If the blades are excessively worn, they must be replaced.
It is a good idea to wear protective gloves before starting to service the shears! These tools are particularly sharp and must therefore be operated carefully and safely.
Cleaning the shears
To carry out a thorough cleaning it is necessary to dismantle the shears, unscrewing the appropriate bolt. If the bolt has oxidized, rusted and is therefore difficult to remove, use WD-40 Super Unlocking rapid action by spraying it with the precision straw around the bolt. This product penetrates quickly and is able to release the pieces effectively!
Once the parts are separated, we act on each part.
We clean all the parts with a plastic brush or other resistant bristles. We then use a lightly abrasive paper to clean the parts. We use a dry cloth to remove any dirt.
As for the blades, after checking them, if they are not very sharp you will need to sharpen them using a sharpening stone (the cote).
Once this operation has been completed, proceed with the waterproofing of the shears.
The recommended product is WD-40 Multifunction capable of protecting this instrument from oxidation and rust. WD-40 Multifunction creates a thin insulating layer on the surface of the blade, which keeps moisture away, as well as performing a lubricating action.
You can also use the same product on all the joints to ensure the tool’s fluidity.
At this point, after the maintenance of the shears has been completed, you can reassemble the parts and check the fluidity of the movement. The work is done and the shears will be ready for the next pruning!
When storing the shears, be careful to leave them slightly open, better if they are hung on a tool wall in a place that is not too humid!
