MK-1080 PAVER SAW OPERATION
CUTTING OPERATIONS
The MK-1080 Paver Saw permits the operator several options for cutting relative to the design of the
saw. The Cutting Head may be adjusted to a fixed position for “FORCED” cutting (the action of pushing
the material steadily into the blade). The material may also be “STEP” cut (the process of passing the
material while adjusting the blade to various depths as a means to incrementally cut the piece). Lastly,
the “CHOPPING” action of the saw can be employed to expeditiously “come down onto” and “push
through” the material in one motion to fully utilize the mechanics of the recoil spring /rolling conveyor
cart. Whatever the preferred technique, please follow these general guidelines:
1. Hold the material firmly against the conveyor cart backstop. Use the rip guide provided to support
and orient the material.
2. DO NOT force the material into the blade! Allow the diamonds to do the grinding.
3. When using a brand new diamond blade, make the first few cuts slowly until the blade is “broken-in”
and cuts freely and easily.
4. After continuous cutting of very hard and dense materials, the blade’s cutting efficiency may slow
down. Should this occur, it can be sharpened by making several passes against very abrasive
material such as: soft cinder block or lightweight sandstone. ENSURE PLENTY OF WATER IS
USED DURING THIS PROCESS!
WARNING
DO NOT operate saw without the blade guard in place. The exposed area of the
blade should never exceed 180 degrees during operation. When installing the
blade, ensure that the blade and flanges are free of sediment, so the fit between
flange and blade is even and true.
NOTICE
A Diamond Blade actually grinds...it does not cut. Not allowing the blade to per-
form the way it was engineered may result in premature blade wear, diamond
“glazing”, steel core warpage, or severe segment damage.
CLEANING & LUBRICATION
The slurry and cutting residue generated by the MK-1080 Paver Saw is considerable. A cleaning and
lubrication schedule must be maintained in order to ensure long and trouble-free operation. As a com-
mon sensible and preventative maintenance practice, clean the dirt and cutting deposits from your
machine after each use. A pressurized spray system may be used, however, never spray around the
electric motor, switch box, or ON/OFF switches. Further, the following lubrication points are advised:
• Place light machine oil where friction, pivoting or rotation occurs between the structural
components.
DO NOT OIL THE MOTOR!
• Pump clean/fresh water for one minute through the Blade Guard Water Tubes to safeguard
against a build up of sediment and the possibility of clogging.
• Rotate the entire Cutting Head Assembly on the Pivot Shaft and lubricate where the casting and
shaft make contact.
