For Electric Models:
• Be sure the “STOP” (red) button is depressed (Figure 4A). Hook up the electrical power source by plugging into
the connector provided. If the cord does not mate with the connector, consult a qualied licensed electrician before
continuing. Be Sure the equipment is properly grounded.
• After completing the previous step, to start the motor, be
sure the Emergency Stop (E-Stop) is in the UP position
(Figuer 2). Press the “START” (green) button (Figure 4A).
• Allow motor to reach operating speed.

Before Starting the Engine:
• Read Rx for Concrete Saws before operating.
• Inspect machine before each use according to the Maintenance Schedule on page 15.
• Locate and be familiar with all engine and saw controls (Figure 2).
• Inspect the blades carefully before installing. Use the correct blade for the job. Check
rated RPM, diameter and size conguration. Make sure blades are correctly mounted.
• For wet cutting, attach supply hose to Water Hook Up Valve (Figure 3).
NOTE: Do not ip Blade Saver switch to WET until after the engine has started.
• Adjust the handles for operator comfort and safe operation. Be sure to retighten
knobs once handles are positioned.
• Be sure cutting line is well dened.
• Move the saw into operating position.
Starting the Engine:
• Check to be sure blade is raised - not in contact with the slab surface and blade
guards are in place.
• Blade Saver switch (Figure 4) must be in the DRY position or engine will not start.
Note: The Blade Saver detects water pressure from the switch to the blade. If water
pressure drops below 2 1/2 gallons per minute, the switch will shut off the engine to
prevent damage to the machine and/or the blade.
• Check that the Emergency Stop (E-Stop) is in the UP position.
• Turn Engine Ignition key to START. After engine starts, leave Engine Ignition in the RUN position. Ignition position
on saw will vary depending on engine. (Review Figure 2)
NOTE: In cold weather, use the Choke to aid starting.
• If wet cutting, open Water Valve (or turn on Water Pump) then ip the Blade Saver switch to the WET position.
Check to be sure water ows freely to the blade. Water should be visible on the ground around the blade.
SS-20 only. For blades marked DRY CUTTING, leave switch in the DRY position. While water is not
required for cooling, it may be used for controlling dust. For health reasons, it is strongly recom-
mended that the operator wear a respirator if cutting dry and water is not being used to control dust
from the material being removed. That dust may contain chemicals known to cause serious illnesses,
including Silicosis a fatal disease of the lungs. Check the chemical properties of the material to be
removed and follow all EPA/OSHA regulations.
