Pre-cut
If a disc saw is used for cutting, care must be taken that the thickness of the cutting blade
matches to the diamond chain. Never use a disc saw with a conventional cutting disc for
cutting. The narrow saw groove produced in this case leads to a jamming of the diamond
chain and can lead to dangerous kickback.
For straight cuts, the method of gradual pre-cutting is appropriate.
Draw the cut, if necessary, a board can also be installed as a guide for the saw cut. Run a 2 cm deep
cut with the bottom of the sword tip across the entire line. Move the sword back to the starting point and
repeat the cut a further 2-3 cm lower. Depending on the thickness of the object being cut, repeat this
procedure several times. Then insert the bar to the desired depth (plunge) and perform the cutting. The
cutting is carried out straight through the cut.
5.3 Tension the diamond chain
An insufficiently strained diamond chain can cause serious or even life-threatening
injuries.
All chains have the tendency to stretch under load. Check the play between the driving links of the chain
and the sword. If the distance is greater than 12mm (1/2 "), the chain is too loose and must be tensioned
(see section 4.4)
5.4 Safety coupling
The integrated safety clutch protects the operator, machine and tool from high mechanical overloads.
Please note that the clutch operation time does not take longer than 3 - 4 seconds, since wear and heat
development will increase greatly.

ATTENTION: Always remove the mains plug from the supply socket before starting
maintenance or repair!
Clean the machine once the sawing work has been completed.
You can sprinkle the machine carefully with a soft jet of water.
Never use a high pressure cleaner or even a steam cleaner.
In order to clean the bar and chain after completion of the work, the diamond chain saw must be operated
at idle speed with maximum water flow for at least 10-20 sec.
After work, we recommend spraying the diamond chain, sword and drive sprocket with oil. This prevents
corrosion and reduces the accumulation of sludge on the components.
If necessary, replenish the chain tensioner area with water-repellent grease.
If the bar is worn out on one side after some time, you can extend the life of the bar by reversing it when
you change the diamond chain. Note: The normal life of a bar is about two to three diamond chains
(incorrect application and increased cutting of reinforcement shortens the life).
Damaged cords and plugs have to be repaired or exchanged exclusively in an authorized repair station
(www.weka-elektrowerkzeuge.de).
If water runs out of the overflow-hole on the gear or on a different place, stop the machine immediately
and let it be repaired in an expert workshop.
The same is valid for the gear oil.
Let the water completely flow out of the system especially in the cold seasons - Danger of frost!
7. F R E Q U E N C Y
The diamond chain saw TK40 is controlled by the water-cooled frequency converter FU6U.
Operate the frequency converter only with a type B residual current circuit breaker.
