mind that your Terrco
piece of machinery manufactured to exacting
standards. In order for you to obtain maximum
®
use of your Terrco

read this manual completely and thoughly
before attempting to operate your machine. A
parts diagram adm parts refenence sheet are

PLELIMINARY PROCEDURES TO FOLLOW
BEFORE PUTTING THE 3100 IN OPERATION
FOR THE FIRST TIME.
A. Delivery of the Machine
1. On delivery, the contractor should very
carefully examine the shipping crate to see that
no part of the machine is damaged. If damage
is noted, request an inspection immediately and
request a copy of the claim report. When
accepting the machine from the delivering
carrier, note the damage on the Freight Bill
before signing. TERRCO
any claims for broken, damaged, or missing
parts that may have occurred in shipment, as
each machine is checked and inspected for the
same, before leaving our plant.
B. Installation and Replacement of Grinding
Stones
1. Move the counterbalancing weights to the
upper weight baskets.
2. Using the flop handle, tilt machine back
so that the caster wheel rests on the floor.
3. Clean mounting surface both on plug
stone and stone holder. On 2" or 3" diameter
plug stone, push stone in the hole and give the
stone a slight twist to be certain it is securely in
place.
4. Grasp machine handle and lower machine
to the floor slowly so that all stones are resting
on the floor. Make certain no stones have fall-
en or loosened while lowering the machine to
the floor.

C. Transport of Machine
1. With counterbalancing weights in the
upper weight baskets, tilt the machine so that
the caster wheel is firmly on the floor. You can
use the flop handle to pull the machine or you
can fold the flop handle over and push from
gear case side.
D. To operate the 3100
1. Disconnect electrical source.
2. Install stones per instructions in #1B.
3. After stones are installed, lower the
machine until it is in operating position.
CAUTION - Never attempt to start the machine
while lowering machine to the floor, as rear
stones will strike on corners resulting in thrown
stones and possible damage to the machine.
4. Before plugging into the electrical
system, check the voltage at the source. The
minimum acceptable voltage is (210/420 Volt,
60 HZ, 3 phase), or (380 Volt, 50 HZ, 3 Phase).
Anything lower than this can result in blown
heaters and possible motor burnout.
5. If the machine is to operate in an area
more than 100 feet from the source, it will be
necessary to use the next larger size cable (#4-
4) from the source to the 100 feet of #6-4 wire
cable that was furnished with the machine.
6. After you have the cable in place, relieve
pressure on the stones by applying your weight
on the handle and push the start button on the
starter switch, then releasing pressure on the
handle to lower the machine to the floor.
7. We recommend that the first pass over
the floor be made with the weights in the upper
weight baskets. After the floor is "roughed"
out, move the weights to the weight baskets
located on the gear case for maximum abrasive
pressure.
8. Be sure to periodically check stone wear,
to prevent grinding with the steel plugs, rather
than the stones.
