Changing Blades
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.
• 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 blade before installing. Check diamond blades for cracks, loose segments
and oversize, worn, or out-of-round arbor holes. (Figure 1) Do not use any questionable
blade since serious personal injury and/or damage of 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 7).
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 bystandards. 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 Model KL-14 has an arbor
shaft speed (uploaded) of 3600 RPM and 3000 RPM under load.
• Do not remove or lift the blade guard unless machine is stopped and all power is disconnected.
Be sure to reinstall blade guard before reconnecting the power source.
• To change blade, rst remove the screw that holds the front of blade guard down. Then rotate the
guard back until guard rests on the rear wheel (Figures 5 & 6). Be sure to reinstall the screw when
done
• 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 should be the same diameter, do not use if they are
di󰀨erent diameters.
