Removing And Installing Plain-End Blades; Blade Tension - Dremel 1800 Manual De Instrucciones

4. Install the blade by inserting one end of the blade
through the access hole in the table and hook the blade
pin in the pin recess in the lower blade holder. Slide the
top blade pin into the pin recess of the upper blade hold-
er. You may need to press down lightly on the upper
blade holder to install the blade.
5. Check to see that the pins are properly located in the
blade holders.
6. To properly secure the blade securely tighten the wing
knob on the upper and lower holders.
7. Tension blade (see BLADE TENSION below).
Removing and Installing
Plain-End Blades
1. Release blade tension by lifting up the Quick Release
Tension Lever (Figure 11) and turn counterclockwise.
2. Open easy access door and loosen the blade wing knob
on the upper and lower blade holders (Figure 9). Remove
blade from the upper and lower blade holders by pulling
forward on blade and then lifting the blade through the
access hole in the table. Slight downward pressure may be
necessary on the upper arm.
NOTE: Table insert may be removed for better access. Table
insert must be replaced before operating the saw.
3. Install the blade by inserting one end of the blade through
the access hole in the table and centering the blade in the
blade slot in the upper and lower blade holders (Figure 10).
4. To properly secure the blade securely tighten the wing
knob on the upper and lower holders.
5. Tension blade (see BLADE TENSION below).
NOTE: In order to cut, and avoid uncontrollable lifting of the
workpiece, the teeth of the blade used on the Scroll Station
should always point downward as shown in (Figure 9) when
installed.

Blade Tension

To tension blade, move Quick Release Tension Lever to
"down" position. As the lever is lowered, tension will be
applied to the blade (Figure 11).
ATTENTION: Moving the lever downward should require
moderate, steady pressure only. If heavy pressure is needed,
the blade is too tight. Loosen tension by rotating the Quick
Release Tension 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
Operation
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 tension lever will be
extended if you back the tension off one-half turn before lift-
ing the lever.
NOTE: It may be necessary to re-adjust the tension lever
when using different types of blades.
