Check to make sure you have received the following parts:
(1) LS18 Saw with Motor and Blade
(1) Accessory Package Containing:
(4) Leveling Feet with Nuts and Washers
(1) Gear Box Oil
(1) Blade Dressing Stick
(1) Operators Manual and Warranty Card
Remove the saw from its packing and check for damage.
Immediately contact the shipping agent if damage is discovered.
Place the saw on a sturdy, at, level surface.
LEVELING SAW
Install leveling bolts in each saw leg.
Adjust bolts in or out as necessary until saw is level.
FILLING GEAR BOX
Remove top plug on gear box.
Add entire contents of oil container to gear box.
Replace plug on gear box.
ELECTRICAL CONNECTION
Make sure all Switches on the Control Box are in the OFF position and the hood is closed.
Plug the Saw Power Cord into a grounded outlet
COOLANT
We recommend LORTONE Cutting Oil #086-010 for optimal results.
Use a neutral petroleum base oil with a high ash point and no additives.
Add approximately 3 gallons of coolant until the bottom 1/2”-3/4” of the blade is covered.
BLADE CARE & DRESSING
YOU MUST DRESS THE BLADE PRIOR TO INITIAL USE.
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.

OPERATION
Setting Feed Rate:
Select the feed rate appropriate for the material, coolant and blade.
Select slow feed rate for hard materials or thick cross sections.
CAUTION: Too fast a feed rate can result in damage to the blade
or saw and is not covered under warranty.
SLOWEST feed rate - Move the feed belt to the LARGEST pulley.
MEDIUM feed rate - Move the feed belt to the MIDDLE pulley.
FASTEST feed rate - Move the feed belt to the SMALLEST pulley.
Clamping Material:
Make sure the switch on Control Box is 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.
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 for desired length of cut.
To Start Saw:
Note: The feed is engaged anytime the saw is running.
Close hood and turn switch to “ON” position.
IMPORTANT- DO NOT LEAVE SAW UNATTENDED
Listen for changes in operating noise. Sudden changes can indicate damaged material or blade.
Over-heating of the drive motor can result in tripping of the safety overload protector. To prevent blade & saw
damage, IMMEDIATELY turn off the “Power” switch. 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 power switch 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).
CLEANING & MAINTENANCE
The saw should be cleaned periodically when sediment builds up to a depth of 1/4”.
Remove the drain cap from the saw case and drain the oil.
Wipe sludge from the case and power feed screw.
Replace the drain cap and add clean or ltered oil.
Bearings come pre-greased from factory. If saw is heavily used,
bearings can be greased through hole in the bearing housing*.
BLADE REPLACEMENT
NOTE: This saw requires and 18” blade with a 3/4” arbor hole.
Remove the arbor nut, outer blade ange, and blade.
Clean the anges.
Install the new blade carefully.
Replace the outer ange and arbor nut and tighten securely.
Do Not Overtighten!
Adjust slab catcher to clear blade by 1/8”.
