- MARK III SAWS blade depth setting

WARNING: 

Beware that after releasing the lever, the blade will continue 

spinning for several seconds. Keep a firm hold on the handle grips and 

maintain control of the machine until the blade completely stops.

6.12 

This machine is intended to be used with a vacuum with 200cfm 

or more at all times.  There is no instance where this machine should be 

used without a vacuum or with water.

6.13 

Determine how deep you want the blade in the joint.  An 8” 

blade will get a maximum of 2” depth and a 7” blade will get a maximum 

of 1.5” depth. 

6.14 

The accurate way: Lay the saw on its side in the same position 

you would to change the blade.  Lower the blade until it is approximately 

where you want it.  Measure with a tape measure or ruler to confirm the 

depth you want.  Move the Brass “depth stop” thumb screw into the hole 

that coincides with the depth adjustment to prevent the blade from being 

lowered further than you want it.  The “fine adjustment” knob on the left 

side of the blade depth adjustment assembly can be screwed in or out to 

make small adjustments to compensate for blade wear.  

6.15 

The quick way:  With the saw “off”, lower the blade on a flat 

surface lifting the front wheels off the ground.  The distance between the 

bottom of the wheel and the ground will be the approximate depth of cut 

+/- 1/8”. 

WARNING:

 It is important to verify the depth of cut immediately after start-

ing, and periodically during the job.  If you are cutting deeper than you 

panned, you will use a lot more joint fill material than you had intended.

SETTING THE BLADE DEPTH

Each notch is 1/8”

6.1 

Follow all pre-operating instructions in section 5.0.

6.2 

The machine should be unplugged from electricity before start-

ing this operation.  

WARNING:

 Never attempt to start the engine with the diamond blade 

inserted in a joint or previous cut. The blade will turn as soon as the MARK 

III is started. This could damage the blade or cause the MARK III to jump 

backwards.

6.3 

Set the blade depth adjustment handle to the lowest point.

(See Figure 9) 

6.4 

Remover the blade guard cover plate 

6.5 

Loosen, counterclockwise, the blade nut and remove it along  

with one of the two spacers.  The inner arbor nut and one spacer will 

remain in place. 

WARNING: 

If the blade you are using has a “5/8-7/8” knockout (brass 

bushing), remove it so that the arbor of the blade is set at 7/8” 

6.6 

Ensure the proper direction of the blade being used.  This ma-

chine rotates the blade in an up-cut rotation which is counterclockwise. 

6.7 

Place the blade on top of the spacer that is already on the ma-

chine and line up the arbor hole. 

6.8 

Place the Outer blade spacer on top of the blade and line up the 

arbor hole.   

6.9 

Insert the shank of the Blade nut through the spacers and blade 

and thread onto the shaft of the grinder and tighten the nut with moderate 

force. Over tightening will cause problems when it’s time to change the 

blade. 

6.10 

Raise the blade depth adjustment to it’s highest point, replace 

the blade guard cover plate. 

 

WARNING:

 Do not twist the blade in the cut. Never attempt to cut any 

pattern or follow any joint that is not a straight line. Do not force the blade 

forward. These actions could damage the blade and MARK III unit.

6.11 

The vacuum port is designed to be used with the 2” cuff that is 

standard on most industrial vacuums in the industry.  The hose is meant 

to have a snug fit to prevent it from falling off during normal operation.  

*Cold weather will make the hose more difficult to slip over the vacuum 

port.
