WATER CONNECTION

Water is a basic requirement for diamond sawing with wet-type
diamond blades. The water serves as a coolant to avoid the working
surface of the diamond segments from overheating.
Water also keeps down dust and flushes away abrasive particles.
WARNING: Always use the PRCD (GFCI) when operating with
water

an electric shock.
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).
Use a water collector with a wet vacuum to collect cooling water if nearby objects could be damaged by water.
The water feed system is built into the machine. To connect with the water supply, first pull the quick-release
collar to remove the female side of the water coupling. Then unscrew the nut and engage the coupling to the
water hose. Now reconnect the water coupling to the male water feed valve. Press it until it clicks.
The water flow is controlled by the water feed valve. The water to the blade may be finely adjusted to the
required amount.
NOTE: Contaminants in the water supply can easily plug up the fine water nozzles in the blade guard.
Ensure that the supply water is clean. If you find that there is no water flow to the blade, then clean out
the water feed system on the machine.
GUIDE ROLLER ASSEMBLY
Butterfly Bolt
The guide rollers make it easier to keep the blade plane perpendicular to
the workpiece. To install, slacken the butterfly bolt slightly and engage the
four claws with the four eyelets on the bottom of the motor housing, then
tighten the butterfly bolt.
OVERLOAD PROTECTION, OVERHEAT PROTECTION
Overload & Load Warning Lamp
When full load is reached, the load warning lamp will flash red. If full load
Load Warning Lamp
is exceeded and sustained for too long, the motor will shut down and the
load warning lamp will glow solid red. In this case, the motor must be first
shut off and then restarted.
Overheat Thermal Protection
If the temperature of the motor gets too high, the thermal protection will
shut the motor down. The switch must be first shut off and then restarted.
When this happens, do not immediately start cutting after restarting the
