Maintenance - DeWalt DCS378 Instruction Manual

English
nOTE: Select and use a band saw blade that is most
appropriate for the material being cut. Refer to Bi‑Metal
Band Saw Blade Description.
This portable band saw may be hung using the hang hook
( , Fig. A). Hang tool on a pipe vise or other suitable,
10
stable structure.

WARNING: When using the hang hook make sure it is
secure and stable before releasing it. The saw may fall
resulting in serious injury to you or others.

WARNING: To reduce the risk of injury, only use hang
hook to support the weight of the tool. Never rely on
the hang hook for your own support or to help you
maintain your balance.

WARNING: Never attempt to use this tool by resting
it upside down on a work surface and bringing the
material to the tool. Always securely clamp the
workpiece and bring the tool to the workpiece, securely
holding the tool as shown in Figure L.

WARNING: Do not use hang hook as lanyard
attachment point.
1. Material to be cut must be rigidly secure where it is or
clamped in a vise or other clamping device.
2. Bring the work stop
6
while keeping the blade off of the workpiece. Turn the
saw on.
3. When saw reaches desired rotation speed, slowly and
gently tilt the main body of the tool to bring the band
saw blade into contact with the workpiece. Do not apply
additional pressure in excess of the weight of the main
body of the tool. Carefully avoid bringing the band saw
blade suddenly and heavily into contact with the upper
surface of the workpiece. This will cause serious damage
to the band saw blade. To obtain maximum service life of
the band saw blade, ensure there is no sudden impact at
the beginning of the cutting operation.
4. Straight cutting can be accomplished by keeping the
band saw blade aligned perpendicular to the material.
Any twisting or cocking of the blade will cause the cut to
go offline and decrease the life of the blade.
NOTICE: During cutting, if the band saw becomes
locked or jammed in the workpiece material, release
the switch immediately to avoid damage to the band
saw blade and motor.
5. The tool's own weight provides the most efficient
downward cutting pressure. Added operator pressure
slows the blade and reduces blade life.
6. End pieces, which would be heavy enough to cause
injury when they drop, after cut‑off, should be supported.
Safety shoes are strongly recommended. End pieces may
be hot and sharp.

Tips for Better Cutting
The following recommendations should be used as a guide
(refer to Recommended Cutting Positions). Results may vary
with the operator and the particular material being cut.
• Never twist the band saw blade during cutting operation.
• Never use liquid coolants with portable band saws.
Use of liquid coolants will cause build‑up on tires and
reduce performance.
• If excessive vibration occurs during the cut, ensure that
the material being cut is securely clamped down. If
vibration continues, change the band saw blade.
• Always keep at least 2–3 teeth engaged in the cut.

MAINTENANCE


WARNING: To reduce the risk of serious personal
injury, turn unit off and remove the battery pack

over a long period of time with a minimum of maintenance.
Continuous satisfactory operation depends upon proper tool
care and regular cleaning.
Lubrication

service is ever needed, take your tool to an authorized
service location.
