Quick start guide

To get a first impression of the KorfkerRest® please follow these steps: 

Step 1

Using the Torx key provided, check that all the Torx screws are tightened before use.

Step 2

If the rest is too tight or too loose for your instrument, adjust it by loosening the Torx screw of the shoulder side leg and tilting the hinge joint inwards or outwards. Tighten the Torx screw again afterwards.

PLEASE OBSERVE THE FOLLOWING: 

If the rubber feet slip during playing they can be tightened by adjusting the legs (see manual).

Manual 

For full benfit of its features and to ensure a long life for your PIRASTRO KorfkerRest®, please read this instruction manual carefully before use.

Bending the rest

The Pirastro KorfkerRest has been pre-bent to a shape that has proven to be comfortable for many players. A unique feature of this rest is that its shape can be changed by manual bending to fit the individual.

WHEN BENDING THE WOOD PLEASE KEEP THE FOLLOWING IN MIND:

  • The fibres of the wood need time to adjust to a new shape, therefore always bend the rest slowly and carefully. Fast and forceful bending will damage the wood and may cause cracking.
  • The rest has a bending limit. By bending it slowly and carefully you will feel when the rest cannot bend any further. Do not force the wood to bend beyond this point. 
  • Please keep in mind that small adjustments can have a significant effect on comfort. 
  • Clamping the rest onto the instrument will increase the shoulder curve slightly. Bear this in mind when deciding the final curve. 
  • When the rest is bent and its shape altered, the legs might need to be readjusted. Please refer to the section entitled »Adjusting the legs«.

Adjusting the legs

Each leg has a Torx screw connecting the hinge joint with the base joint and a Torx flange screw connecting the base joint with the wooden bridge. Locking rings prevent movement between the hinge joint and the base joint and between the base joint and the wood when the Torx screws are tightened correctly. These four locking rings are essential to the functioning of the rest and should be replaced if lost or damaged (4 replacements included).

Adjustments to the legs should be made in small increments. After changing their position, look at both legs sideways and make sure the adjustment screws of the rubber feet are parallel to each other. When placed feet downwards on a flat surface, all 4 tips of the rubber feet should touch the surface. If they are not, adjust the tilt of the hinge joint of the chest leg. 

In order not to change the position of the wooden bridge in relation to the violin, whatever adjustment is made needs to be divided between the shoulder leg and the chest leg. This way the legs will both remain at a similar angle pointing inward. 

After making adjustments always check all screws have been tightened.

See the following video:

Narrowing the rest

Increasing the angle of the hinge joint of the shoulder leg inwards will narrow the rest and create a stronger clamping action. In order to adjust the hinge joint, loosen the Torx screw enough to allow the joint to move. Move it to the desired position and tighten the Torx screw. 
 

A similar adjustment needs to be made to the chest leg. To make the rest narrower, slightly loosen the Torx flange screw and rotate the base joint clockwise. After tightening the Torx flange screw, loosen the hinge joint and swivel the hinge joint inwards. At this point both adjustment screws need to be parallel with each other and all screws need to be tightened.

See the following video:

Video: Narrowing the rest

Widening the rest

Straightening the hinge joint of the shoulder leg by bringing it outwards will widen the rest and create a weaker clamping action. In order to adjust the hinge joint, loosen the Torx screw enough to allow the joint to move. Move it to the desired position and tighten the Torx screw.

See the following video:

Video: Widening the rest

A similar adjustment needs to be made to the chest leg. To make the rest wider, slightly loosen the Torx flange screw and rotate the base joint anticlockwise. After tightening the Torx flange screw, loosen the hinge joint and swivel the hinge joint outwards. At this point both adjustment screws need to be parallel with each other and all screws need to be tightened. 

Adjusting the tilt of the rest

The tilt of the rest can be adjusted as seen in picture below. In order to increase or decrease the tilt of the rest, start with the shoulder leg. Slightly loosen only the Torx flange screw and rotate the whole leg slightly clockwise to increase the tilt or anticlockwise to decrease it.
 

A small rotation will have a noticeable result. After tightening the Torx flange screw, adjust the tilt of the hinge joint of the chest leg by loosening its Torx screw and swivelling the hinge joint so the two adjustment screws are parallel.

See the following video:

Returning the rest to its original position

In its original position and when not attached to the violin, the two hinge joints of the rest lean slightly towards each other. This gives the best grip on the instrument.

To return the rest to the original position it is necessary to adjust the position of the legs. Start with the base joint on the shoulder side (the engraved end of the rest). Loosen the Torx flange screw which secures the base joint of the shoulder leg, rotate the base joint into the position seen on the side of the box and tighten the Torx flange screw. 

Next, loosen the Torx screw which secures the hinge joint of the shoulder leg, position the hinge joint at the angle seen on the box and tighten the Torx screw.

Follow the same steps for the chest leg and the rest should be in its original position.

Replacing the rubber pads

When a rubber pad has worn out, it can be peeled off using the finger lift under the tip of the pad. Peel the backing off one of the replacement rubber pads included with your Cradle. Start by aligning the round hole exactly around the torx flange screw, then align the eyes in the rubber with the eyes in the wood. Aligning the eyes might require slight stretching or compressing of the rubber, depending on how strongly the rest has been bent. Before using, press the whole rubber pad strongly onto the wood, starting at the edges.

Closer to the Player

This adjustment positions the rest closer to the player. The adjustments to the chest and shoulder leg can be made individually.

Higher Position

This adjustment positions the violin higher on the chest side and if desired closer to the player on the shoulder side which results in a more elevated position. Both adjustments can be made individually. 

Violin lower on Chest

This adjustment positions the violin towards the chest.
Using the joints in the opposite direction will position the rest higher up the shoulder.
