Cutting Technique; Maintenance And Cleaning - Carat DS-4000 Mode D'emploi

Cutting Technique

• Holding the machine with both hands to resist
the start up torque, press the release button and
then squeeze the trigger switch.
• Allow the machine to reach full speed before
contacting the workpiece.
• Adjust the water flow as needed by turning the
water feed valve.
• Then gently begin the cut with the rear portion
of the blade until the kerf is established. Make
the first cut in the forward direction (so that you
can see the line of cut). Then make following
cuts in the backward direction.
• Do not try to cut too much depth in one pass.
Never exceed about 50mm (2") per pass.
• It's a good idea to first cut a shallow guiding
groove before proceeding to make the main cut
. If any correction is needed. Lift the blade and cut slightly ahead and then back into the existing kerf. Take
care to avoid the blade being pinched.
• In round workpieces, the best technique is to use a slow, uniform back and forth motion while cutting
with the bottom quadrant of the blade.
• Do not allow the machine to bog down. Limit your feed pressure to keep the blade spinning at high
speed.
• Never side load the blade in the kerf.
• Concrete cutting is very stressful for the motor: After the cut is finished, it is a good practice to run the
machine at no load for a short time to lower the motor temperature before stopping.
Stopping
Release the trigger to stop the machine. After the trigger is released, the blade will continue spinning for a
time.
WARNING: Do not set the machine down until the blade has stopped turning.
Note: Always ensure the vacuum cleaner's dust bag is not too full. An overfilled dust bag will have
reduced dust collection efficiency which could result in poor dust control.

MAINTENANCE AND CLEANING

This machine operates in a very harsh environment. The slurry created by wet cutting and the dust created by
dry cutting gets sucked into the motor's cooling slots and enters the motor. The slurry of brick and concrete
contains salts and other corrosive substances which will severely shorten the life of the motor or cause
electrical shorts if allowed to accumulate.
Therefore, it's essential for the long life of the tool that it be thoroughly cleaned after each use.
Compressed air should be blown through the machine's cooling slots at the back of the machine while the
motor is running.
