sion lever counterclockwise 1-2 turns, then reset the tension lever
to the "down" position. If the tension lever is in the "down" position
and the blade is too loose, you can increase tension by leaving the
tension lever "down" and rotating it clockwise just until you feel the
slack in the blade removed. Then turn the tension lever ONE full
turn clockwise. This amount of blade pressure should do well for
most cutting operations and blades.
When the blade tension has been properly adjusted, you should be able
to lift up the Quick Release Tension Lever, remove and install the blade,
lower the lever and return the original blade tension. The life of the ten-
sion lever will be extended if you back the tension off one-half turn
BEFORE lifting the lever.
It may be necessary to re-adjust the tension lever when using

making any adjustments or changing any accessory.
A main benefit of this saw is the ability to perform intricate interior cuts
quickly and easily. This is best accomplished using the Quick Release
Tension Lever. Simply follow these steps (Figure 11):
1.
Drill appropriate sized pilot hole in work piece.
2.
Release quick release tension lever.
3.
Remove the blade from the upper blade holder as explained in
REMOVING AND INSTALLING BLADES .
4.
Thread blade through pilot hole from underneath the workpiece. If
needed, remove the table insert. This will allow the blade to angle
forward for more clearance between the workpiece and the upper
arm housing. Reinstall the blade in the upper blade holder. Replace
Preventative maintenance performed by unauthorized personnel may
result in misplacing of internal wires and components which could cause
serious hazard. We recommend that all tool service be performed by a
Dremel Service Facility. To avoid injury from unexpected starting or elec-
trical shock, always remove plug from wall outlet before performing serv-
ice or cleaning.
CARBON BRUSHES
The brushes in your tool have been engineered for many hours of
dependable service. To prepare the brushes for use, run the tool at full
speed for 5 minutes under no load. This will properly "seat" the brushes,
and extend the life of the tool. To maintain peak efficiency of the motor,
examine the brushes for wear every 40-50 hours. Using the tool with
worn brushes will permanently damage the motor. Use only original
Dremel replacement brushes. Inspect the multitool brushes after 40-50
hours of use. If the multitool runs erratically, loses power, or makes
unusual noises check the brushes for wear and possible replacement.
Follow these steps to check/change the multitool brushes:
1.
With the power cord unplugged, place the tool on a clean surface.
Use the tool wrench as a screwdriver to remove the brush caps.
2.
Remove the brushes from the tool by pulling on the spring that is
attached to the carbon brush. If the brush is less than 3mm long
and the surface of the brush that touches the commutator is rough
or pitted, the carbon brushes should be replaced. Be sure to check
both brushes.

table insert.
5.
Re-tension blade by pulling tension lever down.
6.
Lower drop foot until it just rests on top of the workpiece and you're
ready to begin cutting.
7.
When finished making the interior scroll cuts simply remove the
blade from the upper blade holder, as described in chapter
REMOVING AND INSTALLING BLADES , then remove the board
from the table.
1.
Loosen the table lock knob, and the saw table can be tilted to the
left and locked at any angle from 0° horizontal cutting position up to
45° for bevel cutting (Figure 12). Your tool also features table tilt
detents which audibly click into place to the left every 15°. The
table may be tilted to the right up to 5°.
2.
A degree scale is provided under the work table as a convenient
reference for setting the approximate table angle for bevel cutting.
When greater precision is required, make practice cuts and adjust
the table as necessary for your requirements.
3.
Loosen the drop foot wing knob and lower by hand until it just rests
above the workpiece surface, then securely tighten the drop foot
wing knob. The drop foot should always rest just above the work-
piece to help prevent the workpiece from lifting off the table.
4.
When cutting with the table angled, adjust drop foot so it's parallel
to the table. To adjust, loosen the wing knob, turn drop foot to cor-
rect angle, tighten wing knob (Figure 12).
Always make sure the blade does not contact either side of the drop foot,
table opening or insert.
MAINTENANCE
3.
If one brush is worn, you should replace both brushes for better
performance of your multitool. Remove the spring from the brush,
throw away the old brush and place the spring on a new brush.
4.
Place the carbon brush and spring back into the tool, there is only
one way the brush will fit back into the tool.
5.
Replace the brush caps onto the tool by turning the cap in a clock-
wise direction. To tighten, use the wrench, but DO NOT OVER
TIGHTEN! After replacing the brushes the tool should be run at no
load; place it on a clean surface and run it freely at full speed for 5
minutes before loading (or using) the tool. This will allow the
brushes to "seat" properly and will give you more hours of life from
each set of brushes. This will also extend the life of your tool since
the commutator surface will also wear better and longer.
Lubricate the bearings with oil after 10 hours of use. Reoil after every 50
hours of use or whenever there is asqueak comming from the bearings.
1.
Remove rubber plug to expose bronze bearing.
2.
Squirt a generous amout of grease around the shaft end an bronze
bearing.
3
Replace the rubber plug.
4.
Let the scroll saw run shortly.
