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 thor-
oughly before attempting to operate your machine. A parts diagram and parts list are included to assist you in order-
ing the proper parts. Always give the machine number and model number when ordering your repair parts.
PRELIMINARY PROCEDURES TO FOLLOW BEFORE OPERATING MACHINE FOR THE FIRST TIME:
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.
The machine has been fully lubricated at the factory before shipping.
ON-THE-JOB INSTRUCTIONS
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  oor so that the handle lays on the  oor.
3. Clean stone mounting surface.
4. IMPORTANT! Install the plug stones in the following manner. Place the stone  rmly 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  oor. 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.
ELECTRICAL AND PLUG-IN INSTRUCTIONS
1. General Instructions
•Always operate your machine with ground faults wired at the electrical source.
•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.
•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.
•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.
•If additional cable is necessary, be sure all connections are of the proper size and that they are tight.
•As a  nal 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.
OPERATING AND MAINTENANCE INSTRUCTIONS
01-S Series

GENERAL MAINTENANCE AND REPAIR INSTRUCTIONS
THE LUBRICATION OF THE MACHINE
1. The lubrication of the main gear case.
•The main gear case contains 6-1/4 pounds of Mobilith AW-1 grease.
•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 13 and 35 on the parts diagram).
2. The lubrication of the wheel bearings.
•Use grease gun and grease each wheel with 1 shot of grease monthly (Ref. number 14 on the Suspension Assembly)
with Mobilith AW-1 or equivalent.
3. Location of other Grease Fittings
•Two  ttings on bearing caps on top of gear case (Ref. number 7). Lubricate these  ttings with Mobilith AW-1 every
month with 2 shots of grease.
•One  tting on foot leveling device (Ref. number 86); recommended grease Mobilith AW-1 or equivalent every six
months with 1/2 shot of grease or as needed.
•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 or as needed.
KEEPING MACHINE CLEAN
1. Schedule daily cleaning after each days grinding.
•Tilt machine back on handle.
•Clean under carriage with water using a garden hose and nozzle.
•Clean all grease  ttings.
2. Do not let any cake-up of cement grinding paste occur as this could create an overload on your machine.
3. Avoid direct spraying of drives/ starter boxes if using a pressure washer to clean the machine.
REPLACEMENTS OF WORN, DAMAGED, OR MISSING PARTS
1. Advantages
•If worn parts (bearings, gears, etc) are not replaced promptly, serious damage to your machine could occur.
•Your machine will operate more effi ciently 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.
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  exible couplings (Ref. number 37) should be changed a minimum of once a year whether you use your ma-
chine or not.
HIGH MOTOR TEMPERATURE
1. Introduction
•“Running Hot” is normal for the smaller, lighter “t” type motor.
•Even though they will run hotter, the “T” motors run more effi ciently.
•Skin cannot withstand a temperature over 135° F yet, most electric motors on Terrco® machines are designed to
operate effi ciently at 165°.
2. Operating Characteristics
•The temperatures of motors are rated by temperature rise and full load over and above room temperature
(25°C or 77°F).
•To convert degree Centigrade to degree Fahrenheit, multiply degree Centigrade by the fraction 9/5 and add 32.
•Older (repulsive-induction) type motors were rated 40° Centigrade rise, or approximately 150° Fahrenheit.

3. Conclusion
•It is recommended that you keep you hands off the motors when they are hot.
•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.
•Also, do not forget we use a thermal protected starters 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.
STONE WEAR AND REPLACEMENT
1. Check your stones for wear periodically, as the stones may be worn  ush with stone holder plugs and the operator
may be grinding with steel stone spiders.
EXCLUSIVE FEATURES OF THE 01-S SERIES
ADVANTAGES OF “T” TYPE MOTOR
1. Less amperage draw.
•15% less in the 5 HP size.
•9-1/2% less in the 7-1/2 HP size.
2. Higher safe operating temperature (165°F)
3. Lightweight.
•42-1/2% less in the 5 HP size.
•34-1/2% less in the 7-1/2 HP size.
4. Less maintenance.
•No brushes.
•Less internal wiring.
DESIGN ADVANTAGES OF NEW MANUAL FOOT LEVELING DEVICE
1. Improved machine control.
2. Faster and greater range of adjustments.
•Six leveling adjustments.
•1/8” increments
3.Simple to operate by merely pushing down on foot lever and raising up on handle.
ADVANTAGE OF LIGHTWEIGHT MACHINE
1. Ease of transportation
2. Still has suffi cient abrasive pressure by use of the removable weights.
TEN POSITION HANDLE
1. Advantages.
•Easier to “break” machine when changing stones.
1. A er 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  oor.
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 “ ip-up”. It also makes it much easier to get at the stone changing area.
2. Operation
•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.
•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.
