BLADE CARE & DRESSING
Clamp a Blade Dressing Stick in the vise. With the hood closed and the saw running, make several cuts
•
through the stick. Repeat as needed.
Dress the blade frequently. Dull or glazed blades will quickly dish or warp.
•
Note: Dished or warped blades are not covered under warranty.
YOU MUST DRESS THE BLADE PRIOR TO INITIAL USE.
•
This removes the protective paint from the cutting edge of the blade.
OPERATION
Make sure all Switches on Control Box are in the “OFF” position (toward saw) before opening the hood.
•
Clamp material securely in vise. Check for looseness of material and re-tighten if necessary.
•
Adjust cross feed and hand tighten the carriage lock screw #488-056. See Fig A.
•
Check to be sure that material will clear the arbor shaft cover and the blade anges.
To release carriage, pull half nut lever toward control box. Slide the carriage to desired position and release
•
the half nut lever. Make sure the lever is fully engaged.
Adjust shutoff chain #447-001 for desired length of cut.
•
To Start Saw:
Note: The “Power” switch operates the motor and supplies power
to the “Feed” switch. The “Feed” switch operates the feed motor only
and will not work with the “Power” switch in the off position.
Close hood and make sure both switches are in the “OFF” position.
•
Turn the “Power” switch to “ON” position to start blade rotation.
•
To start power feed, turn “Feed” switch to “ON” position.
•
Do not operate saw with Hood open.
Turn off both switches and unplug
Failure to follow these instructions
CAUTION
saw prior to opening hood.
can result in serious injury.
While Cutting: IMPORTANT- DO NOT LEAVE SAW UNATTENDED
Listen for changes in operating noise. Sudden changes can indicate damaged material or blade.
•
Over-heating of the main motor can result in tripping of the safety overload protector.
•
Note: Tripping the safety overload protector does not shut off the power feed. To prevent blade & saw
damage, IMMEDIATELY turn off both the “Power” & “Feed” switches. Inspect the machine and blade for
damage and correct any problems before continuing. When cool, press the red reset button on the drive
motor to reset the protector.
At End of Cut:
Push both switches toward saw to “OFF” position before opening the hood.
•
•
Remove the cut slab. Inspect the remaining material to make sure it is secure in the vise.
Loosen carriage lock screw and advance the carriage by turning the cross-feed wheel.
•
Each turn advances the cross-feed carriage approximately 1/16 inch (.062).
The saw should be cleaned periodically when sediment builds up to a depth of 1/4”.
•
Unbolt the saw case from the coolant pan and lift out the case.
•
Empty the coolant pan and wipe sludge from the case and power feed screw.
•
Re-install case in coolant pan, attach bolts, and add clean and/or ltered oil.
•
Unbolt Pan to Clean
