Making A Cut - DeWalt DCS690 Manual De Instrucciones

English
• Always support exposed pipe in the ground so that it
is stable and is able to support weight. Use additional
support closer to the area to be cut to prevent the pipe
from sagging and pinching the cutting wheel.
• Material that is under stress could shift when it is cut.
Uneven pipe beds could exert stress.
• Always make sure the section of material being
removed is also supported. After the first cut is made
you may have to move supports or add additional
support to ensure both sides of the material are
evenly supported.
• Be aware of weakened work areas that could shift or
slide causing your supports to move.
Making Cuts with a Cut-Off Machine

CAUTION: Before attempting to start, grasp tool
firmly with both hands before lifting.

WARNING: Cut-off saw not intended for surface
grinding or other applications where side loading of
the blade is encountered.

WARNING: Edge cutting can be performed only
with wheels that are designed and specified for this
purpose. Protect yourself during edge cutting by
directing the open side of the guard away from you,
the operator.

WARNING: Wheels used for cutting may break or kick
back if they bend or twist while the tool is being used
to do cut-off work.

WARNING: Always be alert for gyroscopic forces that
can be generated by a rapidly spinning cutting wheel.
Moving the cut-off machine sideways can create a
gyroscopic force, causing the operator to experience
an unexpected perpendicular change in direction.
Wet Cut Method (Fig. A, J, K)

CAUTION: Close battery door and securely latch it
closed before using any water.

CAUTION: Never use the saw over head. When using
water, limit cutting to the horizontal position to
reduce the risk of water entering the tool.

WARNING: Wet cut method is to be used only with
a diamond blade.

WARNING: The recommended flow rate should be at
least 20 fl. oz. (0.6 liters) per minute. Cutting at a flow
rate less than recommended or cutting for more than
two consecutive hours requires use of NIOSH/OSHA
approved respiratory protection for the operator and
any bystanders.

WARNING: Maximum supplied water pressure not to
exceed 60 PSI (4.1 bar).

WARNING: Makes sure that water does not flow onto
the abrasive wheel while the cut-off machine is not
in use. The cutting wheel will absorb water which will
affect the balance.
NOTICE: Before using the wet cut method, make
sure water will not damage the material being cut or
surrounding property.

Attaching the Water supply
1. Attach the water supply to the quick water
connector 23 .
2. Attach the quick water connector to the water inlet
Fig. J
3. To regulate the water flow, slowly rotate the water
valve 16 towards to open position until desired flow is
reached as shown in Figure K. To stop the flow of water,
rotate the water valve to the closed postion.
4. Proceed to cut as described in Making a Cut below.
5. After finishing your cuts, run the machine for
3–5 seconds with the water valve closed to remove any
residual water from the cutting wheel.

2. Make sure the trigger switch
and lock-off button is engaged.

Making a Cut


WARNING: Always make sure the guard is in place
and set for the type of cut you are making.

WARNING: Always use your cut-off machine so that
the operator and bystanders are not endangered by
potential airborne particles of material being cut,
sparks, or pieces of damaged cutting wheels.

DANGER: To reduce the risk of serious or fatal injury,
DO NOT change direction during the cut. A change
in direction may produce a high torsional load on the
cutting wheel and cause it to bind or break.

CAUTION: Wear gloves when cutting metal.
