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 perform-
ing any maintenance. All maintenance to be performed by qualified personnel.
2. Never work under equipment without first properly securing the equipment to prevent it from moving or falling. Always
work on a flat and level surface.
3. For Propane and Gasoline Models, refer to the engine manual for maintenance information specific to the engine being
used.
~Be sure to check oil level before operation (while engine is cold).*
~Clean air filter element daily.
4. Grease bearings after every 50 hours of use. Refer to page 12 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 first
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 muounting hardware, refer to page 12.
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 loosen with use. Tighten bolts (4 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 available from
major petroleum companies. These “gas engine oils” are specifically 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 figure on page 12 )
The gear case of your EDCO grinder has been pre-lubricated at the factory with approximately 3 pounds of lubriplate, No.
630-2 grease. We recommend it’s continued use.
Each grinder has an inspection hole in the gear case top plate to tnable you to check the amount of grease in the case. Re-
move 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 overfill. The grease in the gear case should last from three to five
years before there is any need to refill or add. (Note: Models SEC/SGC are not gear driven so this does not apply).
Bearings “B” (refer to figure on page 12)
Each grinder has bearings on top and bottom of the machine. All bearings are self-aligning, sealed units equipped with
grease fittings. 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.
