Maintenance - DeWalt DCS382B Instruction Manual

English

WARNING: This tool has no provision to lock the
switch in the ON position, and should never be locked
ON by any other means.
The variable speed trigger switch will give you added
versatility. The further the trigger is depressed the higher
the speed of the saw.

CAUTION: Use of very slow speed is recommended
only for beginning a cut. Prolonged use at very slow
speed may damage your saw.
Worklight (Fig. A)

CAUTION: Do not stare into worklight. Serious eye
injury could result.
There is a worklight located on the end of the tool near
9
the shoe. The worklight is activated when the trigger switch
is depressed, and will remain on for a short time after the
trigger switch is released. If the trigger switch remains
depressed, the worklight will remain on.
nOTE: The worklight is for lighting the immediate work
surface and is not intended to be used as a flashlight.
Cutting (Fig. A, F, H-K)

WARNING: Always use eye protection. All users
and bystanders must wear eye protection that
conforms to ANSI Z87.1.

WARNING: Exercise extra caution when cutting
towards operator. Always hold saw firmly with both
hands while cutting.
The blade 10 should extend past the pivoting shoe
the thickness of the workpiece throughout the cut. Select
the blade best suitable for the material to be cut and use
the shortest blade suitable for the thickness of the material.
Do not use jigsaw blades with this tool.
nOTE: Before cutting any type of material, be sure it is firmly
anchored or clamped to prevent slipping.
• Place blade 10 and pivoting shoe
to be cut.
• Switch on saw motor and allow it to obtain maximum
speed before applying pressure.
• Always hold saw firmly with both hands while cutting as
shown in Figure F. Whenever possible, the pivoting shoe
must be held firmly against the material being cut. This
will prevent the saw from jumping or vibrating and will
minimize blade breakage.
Flush Cutting (Fig. H)
The compact design of the recipro cating saw motor
housing and pivoting shoe permit close cutting to floors,
corners and other difficult areas.
1. To maximize flush cutting capabilities, insert the blade
shaft into the blade clamp with the teeth of the blade
facing up.
2. Turn the saw upside down so you are as close to the
work surface as possible.
Wood Cutting (Fig. I)
1. Before cutting any type of wood, be sure the workpiece
is firmly anchored or clamped to prevent slipping.

2. Place blade and pivoting shoe firmly against work
to be cut.
3. Switch on saw motor before starting the cut.
4. Always hold saw firmly with both hands while cutting.
Whenever possible, the pivoting shoe must be held
firmly against the material being cut. This will prevent
the saw from jumping or vibrating and minimize
blade breakage.
Metal Cutting (Fig. J)
1. Use a fine tooth blade for ferrous metals and a coarse
tooth blade for non-ferrous materials.
2. In thin gauge sheet metals it is best to clamp wood to
the underside of the sheet. This will ensure a clean cut
without excess vibration or tearing of metal.
3. Avoid forcing cutting blade as this reduces blade life
and causes costly blade breakage.
nOTE: You should spread a thin film of oil or other coolant
along the line ahead of the saw cut for easier operation
and longer blade life. For cutting aluminum, kerosene
is preferred.
Pocket Cutting - Wood Only (Fig. K)
Measure the surface area to be cut and mark clearly with a
pencil, chalk or scriber.
1. Insert blade in blade clamp and tighten blade
clamp securely.
2. Tip the saw backward until the back edge of the
pivoting shoe is firmly on the work surface.
3. Switch motor on, permitting blade to attain
maximum speed.
4. Grip handle steadily and begin a slow, deliberate
upward swing with the handle of the saw.
5. The blade will begin to feed into material. Always
be sure blade is completely through material before
continuing with pocket cut.
NOTE: In areas where blade visibility is limited, use the
edge of the pivoting shoe as a guide.
Project Tips
• Cut only with sharp blades; they cut cleaner, faster and put
less strain on the motor while cutting.
• When cutting, always ensure that the pivoting shoe
is resting against the workpiece. This will improve
operator control and minimize vibration.
• For longer blade life, use bi-metal blades or carbide
tipped blades. These utilize a carbon steel back welded
to high speed steel teeth making the blade more
flexible and less prone to breaking.

WARNING: To reduce the risk of serious personal
injury, turn unit off and remove the battery pack
before making any adjustments or removing/
installing attachments or accessories. An
accidental start‑up can cause injury.
