BLADE SELECTION  
Always select the correct saw blade for the  
3. The number of teeth per inch  
(T.P.I.) affects the smoothness  
and speed of the cut. A wood cut-  
ting blade for general purpose will  
usually have 6-10 T.P.I., a metal  
cutting will have 12-20 T.P.I.  
Another factor is the tooth style  
and how the teeth are set (the  
amount the tooth is bent away  
from the plane of the blade). Most  
blade manufacturer’s provide  
guidelines on their packaging for  
the types of materials and speeds  
to use for a particular blade style.  
Review their guidelines carefully  
before choosing a blade for a par-  
ticular project.  
material being cut. The resulting cut will be  
cleaner and more accurate, and there will  
be less stress on the machine. This Jig  
Saw can be used to cut wood, metal or  
plastics depending upon the type of blade  
selected. The blades used must be of the  
Bosch® style mount. Grizzly offers a variety  
of blade styles in the current catalog.  
A few points to remember in making your  
blade selection:  
1. The overall blade length will affect  
the thickness of material which  
can be cut. Most jig saw blades  
range in length from 3" to 5".  
2. The width of the blade (measured  
from the tip of one of the teeth to  
the back edge) affects how tight of  
a curve can be cut. A 3⁄16" wide  
blade will cut a tighter circle than a  
3⁄8" wide one.  
Figure 2 shows the range of blades for  
wood and metal cutting available from  
Grizzly.

BLADE INSTALLATION  
Turn the switch off and unplug the Jig  
Saw from power before attempting  
blade installation or any adjustments.  
Serious injury may occur if the unit  
should be accidentally started while  
installing the blade  
Make certain the tool is unplugged while  
installing the blade.  
1. Make sure the Orbit Selector  
switch is in Position III. See Figure 3.  
Fig 4. Inserting blade into plunger.  
3. Insert the screwdriver included  
with this Jig Saw into the hole at  
the top front of the saw. See  
Figure 5. Tighten the screw while  
making sure the blade stays in the  
roller groove.  
Fig 3. Orbiter selection in Position III.  
2. Take the blade and turn it so the  
teeth are facing the side of the  
footplate, and insert the mount  
end into the plunger. See Figure 4.  
Twist the blade 90˚ so the teeth  
are now pointing forward, then pull  
it down slightly. Make certain the  
blade is positioned in the groove  
of the roller which backs up the  
blade.

process described above.

ORBITAL ACTION  
straight up and down. This is good for  
There are four settings for orbital action of  
the blade, controlled by a lever switch. The  
effect of the settings is shown in Figure 6  
below. When set on Position III the blade  
oscillates forward in the stroke, which is  
helpful when cutting wood or soft materi-  
als. The Position 0 setting eliminates all  
forward oscillation and the blade strokes  
materials with a strong cutting resistance  
such as metals and where a very clean cut  
edge is desired.  
Changes in the orbital movement can be  
made with the motor turned on.

BLADE SPEED & CHIP BLOWER  
Controlling Blade Speed  
Setting Chip Blower  
Blade speed or stroke rate is controlled by  
a trigger style switch under the handle.  
Speed increases as the trigger is pulled.  
There is also a recessed circular switch in  
the trigger which controls the maximum  
stroke rate. See Figure 7. The switch is  
marked with ranges from 1 to 6 where 1 is  
the lowest stroke rate and 6 is the highest.  
The adjustment is infinitely variable  
between settings.  
The toggle switch next to the orbital move-  
ment selector controls the chip blowing  
device. See Figure 8. When set as shown  
in the photograph the amount of air is at its  
highest level. This is suitable for cutting in  
wood when it is desirable to blow the saw-  
dust out of the way to see the cut line.  
There are two additional settings which  
progressively reduce the amount of air  
delivered. The lowest setting may be used  
for cutting in metal where cutting oil is  
being used and it is not desirable to have  
air move the oil away from the cutting sur-  
face.  
The proper speed depends upon the type  
of material and the blade. Experiment with  
a scrap piece of material when first making  
a cut to see how the cutting action and  
smoothness is. Adjust blade speed and  
the rate of feeding the blade into the work  
until the action is smooth and the motor  
does not slow down excessively.

FOOTPLATE ADJUSTMENT  
The footplate can be adjusted for cutting at  
90˚ to the surface as well as any angle  
from 45˚. To be certain the footplate is  
cutting at precisely 90˚, it is useful to check  
the blade squareness to the footplate with  
the use of a small machinist’s square. See  
Figure 9.  
Fig 10. Setting footplate for angle cuts.  
The footplate can also be set to accommo-  
date flush cutting. This might be used  
when it is desirable to cut right up to a wall  
or other vertical surface. Remove the bolt  
holding the footplate with the Allen®  
wrench. Slide the plate backward so the  
mounting hole lines up with the rearmost  
mounting hole. Reinstall and tighten the  
bolt. The footplate’s front edge will be  
slightly behind the leading edge of the  
blade as shown in Figure 11.  
Fig 9. Checking blade squareness.  
To adjust to another angle, use the sup-  
plied Allen® Wrench to loosen the bolt hold-  
ing the footplate. Slide the plate forward  
slightly to disengage it from the notch, and  
tilt it to the desired angle. At the 45˚ points  
there are notches which position the plate.  
By pushing the plate back when near 45˚,  
the notches will lock the plate in position. If  
an angle between 90˚ and 45˚ is desired,  
set the angle and leave the plate in the for-  
ward position, and tighten the bolt. See  
Figure 10.
