Rules for safer operation
TO AVOID INJURY.
Always inspect saw blades be-
fore use. Replace all cracked
or damaged blades.
Figure 3 - Warning label - inspect blades before use
5.8
Move the front and rear pointer arms down towards the
ground. Turn the height adjustment handle clockwise until the blade
touches the ground. Now turn the adjustment handle counter-clock-
wise one complete 360° turn. This will raise the blade slightly off the
ground.
5.9
Using the marked chalk line or any straight line on the ground,
align the blade with the line. On the pointer wheels, loosen the adjust-
ment nuts and align the wheels with the same chalk line. Push the
MARK III along the line to verify the alignment is straight. See Figure 11
and Figure 12.

CAUTION:
The blade depth is approximate and not exact. Many vari-
ables affect the exact blade depth such as the exact diameter of a worn
diamond blade. If an accurate depth must be cut, install the blade to be
used with the engine in the OFF position. Place the MARK III in a secure
position that allows the blade to overhang and be visibly measured at
full blade depth. An example would be blocking the wheels with the
engine in the OFF position and lowering the MARK III blade along side a
street curb. This will allow a measurement from the bottom of the blade
to the top of the curb.
5.10
Hold the blade guard firmly and remove the bolt in the blade
guard holding bracket. Lower the blade guard down until the 2” caster
wheel touches work surface. Reinsert bolt in the blade guard holding
bracket for future use.
5.11
Make sure the blade guard caster wheel and white dust
urethane seal at the blade guard base are firmly touching the work
surface.
WARNING:
Breathable silica may be generated by use of this product.
Silica can cause severe and permanent lung damage, cancer, and other
serious diseases. Do not breath the dust. Do not rely on your sight
or smell to determine if the dust is in the air. Silica may be in the air
without a visible dust cloud. If air monitoring equipment for silica is not
provided by your employer at your work site, you MUST wear appropriate
respiratory protection when using or servicing the machine. Consult your
employer and OSHA regarding the appropriate respiratory protection.
5.12
Slide the 3” diameter vacuum hose over the connector and
tighten the worm drive hose clamp. Pull firmly on the hose to verify the
connection will not slide off.
