The IBAN/BIC number of K&W Transmissies is NL813231863.B01.

On small orders with a net order value below €500.00, an amount of €10.00 will be charged as an order handling fee.

Shipping costs for delivery addresses in the Netherlands will be charged if the net order value is below €500.00. This is a fixed amount of €15.00 regardless of the quantity or number of items per order.

The method of transport, shipment, packaging and the like, if no particular instructions are given by the customer to K&W Transmissions, is with fixed carrier. The rule is that goods that leave the warehouse today are delivered to the customer the next day. Shipments can be tracked through a track and trace system, because every shipment is provided by K&W Transmissies with a unique barcode. Thus it is always clear where a shipment is and where the shipment must go.

For shipments that must be sent to their destination in the fastest manner possible, K&W Transmissies will look for a custom solution. In many cases, a courier service or express shipment via the fixed carrier can be arranged.

Before the chain is installed, one should check that the execution of the installation complies with the general installation instructions. After this inspection, the chain can be deployed.

• Make sure that when deploying the chain, there is no twist in the chain.
• Support the chain and components, to prevent these from falling.
• When installing the chain, forces in the transverse direction must be collected by a bottom plate or the sprockets.
• Place any connecting link on the slack end and note the placement direction of the quick adhesion springs.
• Do not install new links on a worn chain.
• Do not install new chain on worn sprockets.
• Replace a damaged link as a whole and not just the damaged bottom part.

The chain should be installed according to the usual safety precautions:

• Wear safety glasses, safety gloves and safety shoes.
• Disconnect the power supply of the machine, to avoid switching it on accidentally.
• Use the right tools.

Check the following before switching on the installation:

• Any installation of the connecting link, the clips, the tightening of the nuts and the absence of hard points.
• The presence of foreign objects such as screws, tools, etc., on the chain.
  
  

When switching on the installation:

• Ensure a cautious, gradual start.
• Start the process with a low load.
• Conduct an extra inspection after the installation has been working for several hours or days.
• Ensure the effective forces correspond to the calculations that were taken into consideration when purchasing the chain.

With regard to the lubrication:

• Check the condition and status of any existing nozzles.
• Based on the color and the extent of the soiling of the lubricant, determine whether there is sufficient lubrication or the lubricant needs to be replaced.
• In case of replacement, the installation must be emptied of the lubricant and then filled with a lubricant of the same or better quality.
• First degrease the chain and clean it to remove the dirty lubricant so that it does not prevent the new lubricant from getting between the rubbing surfaces.

If the distance of the deflection of the slack end of the installation is not adjustable, the length of the chain at the start or after normal wear must be shortened in the manner described below.

Balance chains and conveyor chains do not have an offset link and can only be shortened by two links.

Shortening the chain by one link

• Chains with a pitch of up to and including 25.4 mm:

Remove 4 links at one of the ends of the chain, thus the two outer links and two inner links, wherein the outermost link is removed, and then install one double offset link that has a connecting link with spring clip or one outer link (pin link).

• Chains with a pitch that is equal to or greater than 31.75 mm:

Remove 2 links at one end of the chain, thus 1 inner link and one outer link, wherein the outermost link is removed, and then install 1 single offset link.

Shortening the chain by two links

Remove two links at one of the ends, thus one inside and one outside link.

Shortening the chain by one link

• Chains with a pitch of up to and including 25.4 mm:

Remove the adapter switch at the end of the chain.

• Chains with a pitch that is equal to or greater than 31.75 mm:

The chain ends with one single offset link, which also serves as a connecting link, remove the rivets from the outer link and replace these with one connecting link to close the chain.

Shortening the chain by two links

Remove 1 outer link by removing the outermost link on the end opposite the offset link.

The maintenance can be limited to periodically checking the design, performance and lubrication if the implementation is done in a proper manner. However, check regularly:

• The alignment of the sprockets and the wear on the teeth.
• The condition of the chain to determine the level of wear, as traces of wear may indicate incorrect geometry of the installation or improper contact with parts of the frame.
• The wear on the hinges of the chain.
• The wear on the plates of the balance the chains.
• The wear on the bushes and rollers.
• In case of wear of the chain of more than 2% of the length of the chain and more than 5% of the height of the plates, it is preferable to replace the chain and the sprockets and/or the rollers in their entirety.

• The lubrication ensures that there is "liquid" running between surfaces that rub together, preventing them from getting stuck and reducing wear.
• The lubrication protects the chain from corrosion.
• Lubrication provides some noise reduction.
• The lubricant dissipates the energy created by the friction.

Chains come standard with some type of preservative. This means that the chain is provided with some temporary protection in order to prevent rust during storage of the chain. After the chain has been installed, it should be cleaned and then re-greased. There are also lubricants, which can be applied directly to the chain without the chain first being cleaned. These lubricants are meant to be used with the preservatives.

First of all, the chain should not be under tension. That way the lubricant can optimally get between the pins and bushings. Automatic lubrication systems can best be installed from the pulling side of the drive.

Ensure that there is lubrication applied both along the length and along the width of the chain. Along the length of the chain, the hinges should be lubricated in an area where they are less loaded, so that the lubricant can penetrate more easily.

Along the width of the chain, lubricate between the plates to supply the lubricant to the hinge and between the inner plates and the bushes and rollers.

Lubrication can be accomplished in various ways, such as manually with a brush or oil can, with drips or splashes of lubrication, or lubrication under pressure (i.e. spraying, possibly with filtering and cooling of the oil).

The choice of lubricant depends on the type and the linear speed of the roller chain. With lifts and internal conveyors, manual and drip lubrication are often used, but automatic arrangements with a brush or sprayer can also be used.
