1. Disconnect the machine from the power source. Remove the spark plug lead on the propane and
gasoline engine models or disconnect the supply voltage connector at the machine on electric models
before performing any maintenance. All maintenance to be performed by qualifi ed personnel.
2. Never work under equipment without fi rst properly securing the equipment to prevent it from moving or falling.
Always work on a fl at and level surface.
3. For Propane and Gasoline Models, refer to the engine manual for maintenance information specifi c to the
engine being used.
~Be sure to check oil level before each operation (while engine is cold).*
~Clean air fi lter element daily.
4. Grease bearings after every 50 hours of use. Refer to page 13 for lubrication points.**
5. Perform a visual inspection of the entire machine before each operation. Be sure all fasteners are tight and
secure, check for signs of metal cracking or fatigue, inspect for damage to electrical wiring, damage to fuel lines,
check bearings and inspect to be sure proper guards are in place and secure.
6. Inspect belts before each operation. Check belt tension. On new equipment belts should be re-tensioned after
the fi rst few hours of use. Damaged, stretched or excessively worn belts should be replaced with a new matched
set for maximum power transfer.
To tension belts, loosen engine/motor mounting hardware slightly. Adjust the engine/motor position until the belts
are tight. Re-torque the engine/motor mounting hardware, refer to page 8.
Proper belt tension must be maintained to transmit the engine/motor power to the grinding disc. Slipping belts
will overheat, the disc life will be shortened and the cutting speed limited. Over tensioned belts will shorten the
belt and bearing life.
7. Before operation, check Grinding Discs to be sure they are tight. Grinding discs can loosen with use. Tighten
bolts (6 on each disc) as required.
8. Before operation, check Neoprene bushing for wear and replace as necessary.
9. On gasoline and propane models inspect spark plugs. Clean if dirty, replace if the electrodes are burned. Gap
plugs at .020”.
* For Propane Models use a mild detergent motor oil that will not leave ash deposits. “Gas engine oils” are avail-
able from major petroleum companies. These “gas engine oils” are specifi cally blended for long-life on LP-Gas or
natural gas engine operation, which will not carbon up the combustion chamber or shorten valve life. Premium oils
should not be used in LP-Gas or natural gas engines as the metallic detergents will damage the engine valves.
** Gear Case “A” (refer to fi gure on page 13 )
The gear case of your EDCO grinder has been pre-lubricated at the factory with approximately 3 pounds of lu-
briplate, No. 630-2 grease. We recommend it’s continued use.
Each grinder has an inspection hole in the gear case top plate to enable you to check the amount of grease in
the case. Remove this cover with the end of a screwdriver, if grease is visible do not add any. If you cannot see
the grease, add a small amount (1 pound is usually more than enough). Do not overfi ll. The grease in the gear
case should last from three to fi ve years before there is any need to refi ll or add. (Note: Model SEC is not gear
driven so this does not apply).
Bearings “B” (refer to fi gure on page 13)
Each grinder has bearings on top and bottom of the machine. All bearings are self-aligning, sealed units equipped
with grease fi ttings. These bearings should be lubricated every 50 hours of operation with Lubriplate No. 630-2,
or other good bearing grease. DO NOT over lubricate.
An occasional drop or two of oil on the wheel bearings will help prevent binding.
