WATER SUPPLY
This tool must always be used with a supply of clean water at a minimum pressure of at least 1.5bar (20 psi).
The water serves as a coolant to avoid the working surface of the diamond segments from overheating and
since it is not possible to use oil, the water also serves as the only lubricant available for the chain and guide
bar. Sufficient water pressure will maximize chain life.
To connect the water supply, attach the quick-release water coupling
Water Feed Valve
to a water hose and regulate the water flow by adjusting the water
feed valve.
CAUTION: Never use this tool without water, the diamonds will
overheat and the O-rings in the chain will fail from the excessive
Open
heat.
Closed
WARNING: Check all connections of the water feed system to
ensure there are no leaks. Inspect hoses and other critical parts which could deteriorate.
WARNING: The maximum water pressure should not exceed 70 psi (4 bar).
WARNING: Never allow water to enter the motor.
NOTE: Contaminants in the water supply can easily plug up the water nozzles in the water feed system.
Ensure that the supply water is clean. If you find that there is no water flow to the chain, then clean out
the water feed system on the machine.
NOTE: Use a wet vacuum to collect cooling water if nearby objects could be damaged by water.
DIAMOND SEGMENTS
The diamond impregnated segments on a diamond chain operate on a principle of controlled erosion. The
bond matrix holding the diamonds is continually worn away by abrasion with the work piece, exposing the
harder diamonds to stand proud from the bond matrix. Without adequate water, the segments would overheat
and be destroyed. With not enough feed pressure, there would not be adequate erosion of the bond matrix
and the segments will smooth over and become dull. This is called glazing. If the chain seems to refuse to cut
anymore, it is glazed. See below: "SHARPENING A NEW OR GLAZED CHAIN "
Don't feed too gently or the diamond segments will become glazed. If you push too hard, the motor will
overload. Find the sweet spot to keep the chain steadily working.
If the cut is very deep, the work material may be obstructing the flow of cooling water. Expect increased chain
wear in this situation.
NOTE: A new chain will not have its diamonds exposed yet. They will be hidden in the bond matrix. To
open up the diamonds, sharpen in the same manner as a glazed chain below.
