Disconnect the machine from the power source before performing any work on the equipment (i.e.
changing the blade). To disconnect the power source on gasoline engine models, remove the spark
plug lead. On electric models, unplug the electrical power cord at the machine.
• Make sure you have the proper blade for the job. Determine the hardness and composition of the slab. Give your
dealer complete information including whether re-bars are present, the desired depth of the cut, and the length of
the cut. If in doubt, contact the blade manufacturer.
Inspect the blades before installing. Check diamond blades for cracks, loose segments and oversize,
worn, or out-of-round arbor holes (Figure 5 on page 5) . Do not use any questionable blade since seri-
ous personal injury and/or damage to property can result. Do not use warped, twisted, or out-of-balance
blades. Unbalanced blades will wear excessively, vibrate and damage both arbor shaft and bearings.
Do not use a blade without a drive pinhole (Figure 9) .
For safety reasons, EDCO does not recommend the use of any abrasive blades. Abrasive blades can
break and cause serious personal injury to operator and/or bystanders. If abrasive blades are used by
choice, use only reinforced abrasive blades. Inspect abrasive blades carefully.
Never exceed the maximum operating speed of the blade. Be sure to match the blade speed rating
with the arbor shaft speed on the machine. The standard models of the SK-14, SB-14, DS-18 have an
arbor shaft speed (unloaded) of 3600 RPM and 3000 RPM under load.
• Do not remove or lift the bladeguard unless machine is stopped and all power is disconnected. Be sure to rein-
stall blade guard before reconnecting the power source.
• Be sure the arbor shaft, backing plate, and blade cap are clean and in good condition. Make sure the threads are
clean and undamaged. If any damage is detected, consult your
EDCO dealer (or the EDCO factory).
• The backing plate and blade cap (Figure 10) should be the same
diameter, do not use if they are different diameters. For abrasive
blades and for all steel centered diamond blades, the backing plate
and blade cap must be at least 1/4 the diameter of the blade.
• The drive pin should be tight in blade cap and long
enough to fit through blade and into hole in backing
plate.
• Place the blade on the arbor shaft and turn until the
drive pinhole lines up with the backing plate.
•
Place the blade cap on the arbor shaft so the drive pin
goes through the holes in the blade and backing plate.
• Put on washer and arbor shaft nut and tighten arbor
shaft nut.
• Secure the blade guard in the operating position be-
fore reconnecting the power supply or starting engine. Figure 10

Optional:
CE models are equipped with
electrical interlocks. Blade
