SAFTY PRECAUTIONS
-----------------------------------------------------------
This machine is intended for commercial use. It is designed ex-
clusively to grind and polish Terrazzo and concrete floors. Use
only recommended accessories and abrasives.
When the machine is in need of repair, use only Terrco parts.
All operators must read, understand and practice the following
safety precautions.
WARNING: Rotating grinding wheels can cause injury, keep
hands and loose clothing clear.
WARNING: Disconnect power at the machine before servicing
or changing grinding stones.
WARNING: Always check ground (earth) connection prior to
operating machine.
For Safety:
1: Have electrician hook up power to machine.
2: Always operate machine with ground fault protection.
3: Eye, hearing and respiratory protection advised.
4: Service and adjust guards for maximum protection. Never remove the guards.
5: Keep machine clean and properly serviced.

SAFETY PRECAUTIONS WHEN RUNNING
TERRCO GRINDERS
A.Have a qualified electrician hook up correct power
to the machine, grounded properly, with correct
breakers at electrical source.
B.When breaking down machine to change stones or to
check machine always disconnect power to the
machine.
C.Check for wear to ensure no exposed wires.
D.When grinding wet, employees must wear proper
footwear.
E.Always wear appropriate safety protection such as
eyewear, hearing and if needed respiratory
protection.
F.When grinding, watch for problems on the floor such
as bad joints, electrical covers, studs that can cause
injury to operator or machine.
G.Keep machines clean so any potential problems are
visible.
H.When using base machines, use guards for wet or
dry grinding.
I. Also when using base machines, operate with
flexible shaft and housing as parallel to motor as
possible to avoid kinks. Keep flex-shaft greased.

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® 6200 is a precision piece of
machinery manufactured to exacting standards.
In order for you to obtain maximum use of your
TERRCO® 6200, 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 6200 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. 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 6200
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.

General Maintenance for your TERRCO® 6200
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 grease with 1/2 shot once every six months on each wheel with
Mobilith AW-1 or equivalent.
3. Location of the grease fittings.
a. Eight fittings on bearing caps on top of gear case (Ref. No. 10). Lubricate these
fittings with three shots of Mobilith AW-1 or equivalent every six months.
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. 34) 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.
