Operating Instructions
INTRODUCTION:
This manual has been prepared to assist you in
the proper operation and maintenance of your
machine. Please bear in mind that your
TERRCO®2000 is a precision piece of
machinery manufactured to exacting standards.
In order for you to obtain maximum use of your
TERRCO®2000, we suggest that you read this
manual completely and thoroughly before
attempting to operate your machine. A parts
diagram and parts reference sheet are included
to assist you in ordering the proper parts.
Always give the machine number and model
number when ordering repair parts.
PLELIMINARY PROCEDURES TO FOLLOW BE-
FORE PUTTING THE 2000 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®WILL NOT honor
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. 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
fallen 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
push from gear case side.
D. To operate the 2000
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 (208 Volt, 60
HZ, single phase), (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.

General Maintenance for your TERRCO®2000
A. The Lubrication of the Machine
1. The lubrication of the main gear case
a. The main gear case contains Mobilith AW-1 grease.
b. Gear case grease level must be checked once a year. The level of grease in the gear
case should be up to half the thickness of the helical gears. (Ref. No. 20 on the parts
diagram).
2. The Lubrication of the Wheel Bearings.
a. Use grease gun and give a 1/2 shot of grease once every six months on each wheel
with Mobilith AW-1 or equivalent.
3. Location of the grease fittings.
a. Four fittings on bearing caps on top of gear case (Ref. No. 10). Lubricate these
fittings with 2 shots of grease every six months with Mobilith AW-1 or equivalent.
B. Keeping Machine Clean
1. Daily schedule after each day’s grinding.
a. Tilt machine back on handle.
b. Clean under carriage with water using garden hose and nozzle.
c. Clean all grease fittings.
2. Do not let any cake-up of cement grinding paste occur as this could create an overload on
your machine as well as more weight to push.
C. Replacement of worn, damaged, or missing parts.
1. Advantages
a. If worn parts (bearings, gears, etc.) are not replaced promptly, serious damage to your
machine could occur.
b. Your machine will operate more efficiently with new TERRCO®parts.
2. Use only authorized TERRCO® parts as our warranty will not apply if other than factory
authorized TERRCO®parts are used.
D. Morflex Flexible Couplings
1. Bolts (Ref. No. 32) should be checked weekly for tightness. Loose bolts cause extreme
vibration and premature failure of rubber inserts in the couplings.
2. Your flexible couplings (Ref. No. 41) should be changed a minimum of once a year
whether you use you machine or not.
E. Stone Wear and Replacement.
1. Check your stones for wear periodically, as the stones may be worn flush with stone
holder plugs and the operator may be grinding with the steel stone spiders.
