Operating and Maintenance Instructions
Introduction
This Manual has been prepared to assist you
in the proper maintenance and operation of
your Terrco® Machine. Please bear in mind
that your 501-S or 701-S machine is a
precise piece of machinery manufactured to
exacting standards. In order for you to
obtain maximum use of your machine, we
suggest that you read this manual completely
and thoroughly before attempting to operate
your machine. A parts diagram and parts list
are included to assist you in ordering the
proper parts. Always give the machine
number and model number when ordering
your repair parts.
I. Preliminary Procedures to Follow
Before Operating Machine for the
First Time
A. Delivery of Machine
1. On delivery the contractor should very
carefully examine the shipping crate to
see that it has not been mishandled.
Before accepting the shipment, uncrate
the machine and very carefully examine
the machine to ensure that nothing has
been damaged. If damage is noted,
request an inspection immediately and
request a copy of the claim report. When
accepting the machine from the delivery
carrier, note the damage on the bill of
lading before signing.
2. Terrco®will not honor any claims for
broken, damaged, or missing parts that
may have occurred in shipping, as each
machine is checked and inspected before
leaving our plant.
B. The machine has been fully
lubricated at the factory before
shipping.
II. On-The-Job Instructions
A. Installation Instructions—Stones
1. Remove the weights and raise adjustable
handle as far forward as possible, lock
into position and put one foot on the
rubber-tired wheel.
2. Tip the machine back to the floor so that
the handle lays on the floor.
3. Clean stone mounting surface.
4. IMPORTANT! Install the plug stones
in the following manner. Place the stone
firmly into the plug stone holder and
twist.
5. After the stones are installed raise the
machine until it is in operating position
with all stones on the floor. Lower
handle to position best suited for the
operator, and replace the removable
weights.
6. CAUTION! NEVER ATTEMPT TO
START THE MACHINE WHILE
LOWERING TO THE FLOOR, as the
rear stones will strike on the corners
resulting in thrown stones and possible
damage to the machine.
B. Electrical and Plug-In Instructions
1. General Instructions
a. Always operate your machine with
ground faults wired at the electrical
source.
b. Low voltage is a common occurrence on
many terrazzo jobs, and hence it is
necessary that the terrazzo contractor
know his incoming voltage and amperage
at the machine.
2

c. As a result of the low voltage and the use
of a 230 Volt motor, Terrco®has
installed a booster box with pre-wired
plugs already connected to your machine.
d. If the machine is to operate on an area
more than 100 feet from the electrical
source it will be necessary to use the next
lower number (larger) size cable from the
source to the 100 foot wire cable that we
furnished with the machine.
e. If additional cable is necessary, be sure
all connections are of the proper size and
that they are tight.
f. As a final step before starting the
machine, we strongly recommend that a
voltage reading is taken; this requires
very little time and could save a great
deal of trouble.
III. General Maintenance and Repair
Instructions
A. The Lubrication of the Machine
1. The lubrication of the main gear case.
a. The main gear case contains
6-1/4 pounds of Mobilith AW-1
grease.
b. Gear case level shoud be checked
once a year. The level of the
grease in the gear case should be
up to half the thickness so the
helical gears (Ref. number 3 and
4 on the parts diagram).
2. The lubrication of the wheel bearings.
a. Use grease gun and grease every
six months with 1 shot of grease,
(fitting Ref. number 96 on the parts
diagram) on each wheel with
Mobilith AW-1 or equivalent.
3. Location of other Grease Fittings
a. Two fittings on bearing caps on top
of gear case (Ref. number 86).
Lubricate these fittings with
Mobilith AW-1 every six months
with 3 shots of grease
b. One fitting on foot leveling device
(Ref. number 86); recommended
grease Mobilith AW-1 or
equivalent every six months with
1/2 shot of grease.
c. There are four shoulder bolts
located at the pivot points of the
handle bar that require 1/2 shot of
Mobilith AW-1 or equivalent every
six months.
B. Keeping Machine Clean
1. Schedule daily cleaning after each days
grinding.
a. Tilt machine back on handle
b. Clean under carriage with water
using a 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.
C. Replacements 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. number 87) should be
checked weekly for tightness. Loose
bolts cause extreme vibrations and
premature failure of rubber inserts in the
couplings.
2. Your flexible couplings (Ref. number 37)
should be changed a minimum of once a
year whether you use your machine or
not.
3

E. High Motor Temperature
1. Introduction
a. “Running Hot” is normal for the
smaller, lighter “t” type motor.
b. Even though they will run hotter,
the “T” motors run more
efficiently.
c. We as human beings, cannot
stand a temperature on our skin
over 135° Fahrenheit, yet, most
electric motors on Terrco®
machines are designed to operate
efficiently at 165° .
2. Operating Characteristics
a. The temperatures of motors are
rated by temperature rise and full
load over and above room
temperature (25°C or 77°F)
b. To convert degree Centigrade to
degree Fahrenheit, multiply
degree Centigrade by the fraction
9/5 and add 32.
c. Older (repulsive-induction) type
motors were rated 40° Centigrade
rise, or approximately 150°
Fahrenheit.
3. Conclusion
a. It is recommended that you keep
you hands off the motors when
they are hot.
b. If you desire to know the
temperature of the motor do the
following:
(1). Place a 200°F
thermometer on the frame
of the motor
(2). Place a glob of putty over
the bulb of the
thermometer.
(3). Take the temperature
readings.
c. Also, do not forget we use a
thermal protected starter on
Terrco®machines, and this
protects the motor against low
voltage and overload conditions
which might raise the temperature
of the motor beyond safe limits.
F. Stone Wear and Replacement
1. Check your stones for wear periodically,
as the stones may be worn flush with
stone holder lugs and the operator may
be grinding with steel stone spiders.
IV. Exclusive Features of the 01-S
Series
A. Advantages of “T” Type Motor
Design
1. Less amperage draw.
a. 15% less in the 5 HP size.
b. 9-1/2% less in the 7-1/2 HP size.
2. Higher safe operating temperature
(165°F)
3. Lightweight.
a. 42-1/2% less in the 5 HP size.
b. 34-1/2% less in the 7-1/2 HP size.
4. Less maintenance.
a. No brushes.
b. Less internal wiring.
B. Advantages of New Manual Foot
Leveling Device
1. Improved machine control.
2. Faster and greater range of adjustments.
a. Six leveling adjustments.
b. 1/8” increments
3. Simple to operate by merely pushing
down on foot lever and raising up on
handle.
C. Lightweight machine for ease of
transportation and yet has sufficient
abrasive pressure by use of the
removable weights.
4

D. Ten Position Handle
1. Advantages.
a. Easier to “break” machine when
changing stones.
(1). After removing the
weighs, unscrew safety
knob (Ref. number 107),
push knob (Ref. number
18) to the rear to release
the locking mechanism.
Raise handle two or three
notches, lock handle by
reversing the above
procedure and tilt stone
holders off the floor.
(2). Pushing the handle for
ward two or three notches
creates a safe stone
position for changing, as
the machine will not have
a tendency to “flip-up”. It
also makes it mush easier
to get at the stone
changing area.
2. Operation
a. The adjustable handle is very easy
to operate. You merely unscrew
the safety knob (Ref. number 107),
push knob (Ref. number 18) to the
rear to release the locking
mechanism. When you have raised
or lowered the handle to your
desired position, push knob (Ref.
number 18) forward as far as you
can and screw the safety knob
(Ref. number 107) tight. This will
lock the handle in position.
b. Make sure that you have pulled
knob (Ref. number 18) completely
to the rear to assure full unlocking
of mechanism and the safety knob
(Ref. number 107), is screwed up
tight.
