Disconnect the machine from the power
source before performing any work on the
equipment. To disconnect the power source remove the spark
plug lead on gasoline and propane models or unplug the elec-
trical models at the grinder.
2. Tip Grinder back on the handle until handle remains on
contact with the slab. NOTE: FOR GASOLINE MODELS,
TAKE CARE THAT GASOLINE OR OIL DOES NOT SPILL
FROM THE ENGINE, Turn gasoline cutoff valve off. Brace
securely or have someone hold the handle against the slab.
The grinding discs will be visible and accessable for inspec-
tion and installation of accessory items.
3. Installing Multi-disc assemblies (for use with scarafiers,
silabide pads, wire brushes and Dyma-Serts). The multi-discs
are designed as lefthand (LH) or righthand (RH) depending on
the direction of rotation: the LH is on the left side (clockwise)
and RH is on the right side (counter clockwise) as viewed from
the bottom side of the machine. The single disc grinders use
the RH disc. NOTE: Multi-Discs come standard with the EDCO
grinders in this manual. The multi-disc assemblies use a 3/8"
dia. x 2" long roll pin to attach them to the shaft(s) under the
grinder (refer to page 11).
4. When installing the surfacer disc assemblies instead of
the Multi-disc assemblies (refer to figure 7). The discs are
triangular and must be allowed to pass each other without
colliding.
5. Installing grinding stones. Grinding stones are used on the
multi-disc assembly. A total of 3 stones are used with each
multi-disc and are held in place with a hardwood wedge. The
wedges are placed on the inside of the stone (refer to page
10). Use a second wedge and hammer or mallet to drive the
wedge securely ito place.
6. Installing wire brushes. The steel wire brushes are used
on the multi-disc assembly (3 per multi-disc). They are held
in place with a hardwood wedge driven in on the inside of the
brush toward the center of the disc, refer to the previous page.
All accessories are held in place in the same manner.
7. Installing Scarifiers. The scarifier assemblies consist of
disposable scarifiers and a reusable scarifier case. The case
is held into the multi-disc assembly with a hardwood wedge
driven in on the inside of the case toward the center of the
disc, refer to the previous page. All inserts are held in place in
the same manner.
