motor audibly slows by about 20-30%.
This will keep the diamonds sharp.
Use the bumper spike for leverage to
assist in keeping pressure on the
cutting face.
Square Cut-outs
•
When the tool is operating within its normal
load range, the LED load indicator will glow
green.
•
When performing large square cut-
outs, after the initial shallow outline
cut, carefully hold the saw as squarely
as possible and plunge cut each of the
corners all of the way through.
•
Make the bottom horizontal cut first,
then drive some wedges into kerf of
the bottom if the cut section is large
and heavy. Next, perform the 2 side
vertical cuts. Make the top horizontal
cut last.
•
This cutting sequence will avoid the chain
being pinched by the workpiece.
WARNING: Ensure that appropriate
bracing is in place to control falling of the
concrete as the final cut is completed.
Concrete is extremely heavy and could
lead to severe injury if it falls in an
uncontrolled manner.
Pipe Cutting
•
When cutting a concrete pipe,
support the pipe so that it will not
pinch the chain. Plunge straight
through the pipe, leaving a tab of
uncut material at the very top, which
will keep the pipe stable while cutting.
Cut this tab last to complete the cut.
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 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 heat.
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.
