• Air vents often cover moving parts and should be avoided. Loose clothes, jewelry or
long hair can be caught in moving parts.
• An extension cord must have adequate wire size (AWG or American Wire Gauge)
for safety. The smaller the gauge number of the wire, the greater the capacity of the cable,
that is 16 gauge has more capacity than 18 gauge. An undersized cord will cause a drop in
line voltage resulting in loss of power and overheating. When using more than one extension
to make up the total length, be sure each individual extension contains at least the minimum
wire size. The following table shows the correct size to use depending on cord length and
nameplate ampere rating. If in doubt, use the next heavier gauge. The smaller the gauge
number, the heavier the cord.
WARNING: Always plug extension cord into a GFCI protected outlet.

WARNING: ALWAYS use safety glasses. Everyday eyeglasses are NOT safety glasses.
Also use face or dust mask if cutting operation is dusty. ALWAYS WEAR CERTIFIED SAFETY
EQUIPMENT:
• ANSI Z87.1 eye protection (CAN/CSA Z94.3),
• ANSI S12.6 (S3.19) hearing protection,
• NIOSH/OSHA/MSHA respiratory protection.
WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other
construction activities contains chemicals known to the State of California to cause cancer, birth
defects or other reproductive harm. Some examples of these chemicals are:
• lead from lead-based paints,
• crystalline silica from bricks and cement and other masonry products, and
• arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you do this type of work.
To reduce your exposure to these chemicals: work in a well ventilated area, and work with
approved safety equipment, such as those dust masks that are specially designed to filter out
microscopic particles.
• Avoid prolonged contact with dust from power sanding, sawing, grinding, drilling,
and other construction activities. Wear protective clothing and wash exposed areas
with soap and water. Allowing dust to get into your mouth, eyes, or lay on the skin may
promote absorption of harmful chemicals.
WARNING: Use of this tool can generate and/or disperse dust, which may cause serious and
permanent respiratory or other injury. Always use NIOSH/OSHA approved respiratory protection
appropriate for the dust exposure. Direct particles away from face and body.
WARNING: Always wear proper personal hearing protection that conforms to ANSI
S12.6 (S3.19) during use. Under some conditions and duration of use, noise from this product
may contribute to hearing loss.
• The label on your tool may include the following symbols. The symbols and their definitions
are as follows:
V ..................volts
Hz ................hertz
min ..............minutes

Motor
Be sure your power supply agrees with the nameplate marking. Voltage decrease of more than
10% will cause loss of power and overheating. D
not operate, check power supply.
COMPONENTS (Fig. 1)
WARNING: Never modify the power tool or any part of it. Damage or personal injury could
result.

L. Water nozzle
Switch (Fig. 1, 2)
WARNING: To avoid the possibility of the appliance plug or receptacle getting wet, position
the saw to one side of a wall mounted receptacle to prevent water from dipping onto the
receptacle or plug. The user should arrange a "drip loop" in the cord connecting the saw to a
receptacle (Fig. 2). The "drip loop" is that part of the cord below the level of the receptacle, or
the connector if an extension cord is used, to prevent water traveling along the cord and coming
in contact with the receptacle.
CAUTION: Before plugging in tool, always check to see that the switch actuates properly and
returns to the OFF position when released.
1. Depress and hold the switch (B) to start operation.
2. For continuous operation, press the lock-on button (C) and release the switch. To disengage
the locking button, depress then release the switch.
ASSEMBLY
WARNING: To reduce the risk of injury, turn unit off and disconnect it from power
source before installing and removing accessories, before adjusting or when making
repairs. An accidental start-up can cause injury.
To Install the Diamond Blade (Fig. 1, 3)
1. Place saw on a stable surface.
2. Place blade (D) on spindle.
3. Using the flange wrench (V) provided, hold the external flange (E)
4. Turn the clamping screw (F) counterclockwise to tighten. Use the T-handle wrench (W)
provided to secure tightly.
5. To remove the blade, reverse this procedure.
Mounting the Wet Cut System (Fig. 1)
WARNING: A Ground Fault Circuit Interrupter (GFCI) is provided on the cord set. DO NOT
use the tool if the cord set is damaged or the Ground Fault Circuit Interrupter (GFCI) fails the
before use test. Replacement of the cord set and plug should be performed by a D
factory service center, a D
WALT authorized service center, or other qualified service personnel.
E
Always use identical replacement parts.
WARNING: Receptacles are available having built in GFCI protection and may be used for
an added measure of safety. When using an extension cord, always plug into a GFCI protected
receptacle or outlet.
This system minimizes airborne dust particles while improving cutting quality and blade life.
1. Loosen the depth adjustment knob (M) and pull shoe (N) to it's minimum depth of cut
position.
2. Using a screwdriver, remove the screw (K) located next to the depth adjustment knob
mounted to the casting.
3. Position the water valve assembly such that the hole in the water valve assembly aligns with
the screw hole located in the casting and the forked water valve (L) straddles the blade.
4. Secure in place with screw. DO NOT overtighten the screw; this could damage the water
valve assembly.
Water Valve Assembly (Fig. 1)
WARNING: Never use water valve assembly without a properly functioning pressure
regulator. This could cause damage to the water tubing if excessive pressure builds up.
1. Never use the saw over head. When using water, limit cutting to the horizontal position to
reduce the risk of water entering the tool.
2. Prior to using the tool with the water valve assembly, inspect water tubing (G) for holes
cracks or other damage. Replace with identical replacement parts if a potential weakened or
damaged area is found. Check connections at the tool inlet (H), water valve and adapter (I)
for leaks. If the connection is loose or the tubing is relaxed around barbs, disconnect tubing,
trim tubing back approximately 1" (25.4 mm), then reconnect tubing. Ensure that tubing is
pushed all the way past the barb(s). Check to ensure tight connection.

3. When using the water kit, always use the water pressure regulator (J) provided. The pressure
regulator can handle up to an 80 psi water source. Firmly attach the regulator to the water
source, but do not overtighten. Be sure to use the filter washer (inside regulator intake
end) to prevent contaminates from clogging water jet ports. If regulator is lost or damaged,
replace with identical replacement parts.
OPERATION
WARNING: To reduce the risk of injury, turn unit off and disconnect it from power
source before installing and removing accessories, before adjusting or when making
repairs. An accidental start-up can cause injury.
WARNING: Use the appropriate blade. Do not use cracked, damaged or excessively worn
blades. Do not use to cut wood or metal.
CAUTION: Wait for the blade to reach the maximum speed and use a slow even feed for
proper cutting.
CAUTION: The DWC860W should only be used on horizontal surfaces (see Water Valve
WALT
E
Assembly).
CAUTION: Use clamps or other practical way to secure and support the workpiece to a
stable platform. Holding the work by your hand or against your body is unstable and may lead
to loss of control.
Proper Hand Position (Fig. 8)
WARNING: To reduce the risk of serious personal injury, Always use proper hand position
as shown.
WARNING: To reduce the risk of serious personal injury, always hold securely in anticipation
of a sudden reaction.
Proper hand position requires one hand on the main handle (U) and the other hand on the front
handle (T) as shown.
NOTE: Figure 8 shows the proper hand positon for a left-handed person. For a right-handed
person, reverse the hand positions.
Depth of Cut Adjustment (Fig. 4)
1. Loosen the depth adjustment knob (M) to release.
2. Move the shoe (N) up or down to desired position.
3. Tighten the depth adjustment knob.
WET CUT METHOD (FIG. 1, 4)
