DeWalt DWE7491 - Basic Saw Cuts; Through-Cutting Operations

18
ENGLISH
Ensure the machine is placed to satisfy your ergonomic
conditions in terms of table height and stability. The machine
site shall be chosen so that the operator has a good overview
and enough free surrounding space around the machine that
allows handling of the workpiece without anyrestrictions.
To reduce effects of increased vibration, make sure the
environment is not too cold, the machine and accessory are well
maintained and the workpiece size is suitable for thismachine.

WARNING:
• Ensure the machine is placed to satisfy ergonomic
conditions in terms of table height and stability. The
machine site shall be chosen so that the operator
has a good overview and enough free surrounding
space around the machine that allow handling of the
workpiece without anyrestrictions.
• Install the appropriate saw blade. Do not use
excessively worn blades. The maximum rotation speed
of the tool must not exceed that of the sawblade.
• Do not attempt to cut excessively smallpieces.
• Allow the blade to cut freely. Do notforce.
• Allow the motor to reach full speed beforecutting.
• Make sure all locking knobs and clamp handles
aretight.
• Never place either hand in the blade area when the
saw is connected to the electrical powersource.
• Never use your saw for freehand cuts!
• Do not saw warped, bowed or cupped workpieces.
There must be at least one straight, smooth side to go
against the rip fence or mitrefence.
• Always support long workpieces to preventkickback.
• Do not remove any cut-offs from the blade area while
the blade isrunning.
Switching On and Off (Fig. N)
The on/off switch
8
of your saw bench offers
multipleadvantages:
• No-volt release function: should the power be shut off for
any reason, the switch has to be deliberatelyreactivated.
• To switch the machine on, press the green startbutton.
• To switch the machine off, press the red stopbutton.
Lock Off Feature Instructions
A cover above the switch folds down for insertion of a padlock
to lock the saw off. A padlock with a maximum diameter of
6.35mm and minimum clearance of 76.2 mm isrecommended.
Guard Operating Feature (Fig. O)

WARNING: To reduce the risk of injury, turn unit off and
disconnect machine from power source before installing
and removing accessories, before adjusting or changing
set-ups or when making repairs. An accidental start-up
can cause injury.
1. The clear side guard(s) will lock in place when in the
raisedposition.
2. This feature increases visibility when measuring the blade to
fence distance.
3. Push down on guard(s) and they will release to the
operating position.
NOTE: Pull on the anti-kickback assembly to ensure it is
locked in place. ALWAYS make sure both guards are in the
down position in contact with the table before operating.
Rip Fence Operation (Fig. P–S)
Rail lock lever
The rail lock lever
5
locks the fence in place preventing
movement during cutting. To lock the rail lever, push it down
and toward the rear of the saw. To unlock, pull it up and toward
the front of thesaw.
NOTE: When ripping, always lock the rail locklever.
Work Support Extension /
Narrow Ripping Fence
Your table saw is equipped with a work support extension to
support work that extends beyond the sawtable.
To use the narrow ripping fence in the work support position,
rotate it from its stored position as shown in FigureQ, and
slide the pins into the lower sets of slots
27
on both ends of
thefence.
To use the narrow ripping fence in the narrow ripping position,
snap the pins into the upper sets of slots
28
on both ends of
the fence. This feature will allow 51mm of extra clearance to the
blade. Refer to FigureP.
NOTE: Retract the work support extension or adjust to narrow
rip fence position whenever working over thetable.
NOTE: When using the narrow ripping fence, subtract 51mm
from the indicated rip scalereading.
Fine Adjustment Knob
The fine adjustment knob
4
allows smaller adjustments when
setting the fence. Before adjusting, be sure the rail lock lever is in
its up or unlocked,position.
Rip Scale Pointer
The rip scale pointer will need to be adjusted for proper
performance of the rip fence if the user switches between thick
and thin kerf blades. The rip scale pointer only reads correctly
when the fence is installed in position 1 or 2 to the right side
of the blade. When using the narrow ripping fence for narrow
ripping (not in work support position), subtract 51mm from
the indicated rip scale reading. See Adjusting the Rip Scale
underAdjustments.
