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 Terrco® 6200 is a precise 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 list are included to assist you in ordering 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. Move the counterbalancing weights to the upper weight baskets.
2. Tilt the machine back so that the caster wheel rests on the  oor.
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 the machine slowly to the  oor. Make certain no stones have fallen or loosened
while lowering the machine.
5. Return the counterbalancing weights to the lower weight baskets.
TRANSPORTING THE MACHINE
1. With the counterbalancing weights in the upper weight baskets, tilt the machine so that the caster wheel is  rmly on
the  oor. You can push from the gearcase side or use the  op handle to pull.
TO OPERATE THE MACHINE
1. Disconnect the electrical source.
2. Install the stones per instructions in installation section.
3. After stones are installed, lower the machine until it is in operating position.
CAUTION! - Never attempt to start the machine while lowering it to the  oor, as rear stones will strike on corners
resulting in thrown stones and possible damage to the machine and/or  oor surface.
4. Before pluggins 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 200 feet from the source, it will be necessary to use the next larger
size cable than the cable that was furnished with the machine.
MODEL 6200
OPERATING AND MAINTENANCE INSTRUCTIONS

6. After you have the cable in place, relieve pressure on the handle and push the start button on the starter switch, then
releasing the pressure on the handle to lower the machine back to the  oor.
7. We recommend that the  rst pass over the  oor be made with the weights in the upper wight baskets. After the  oor
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 AND REPAIR INSTRUCTIONS
THE LUBRICATION OF THE MACHINE
1. The lubrication of the main gear case.
•The main gear case contains Mobilith AW-1 grease.
•Gear case level shoud be checked once a year. The level of the grease in the gear case should be half way up, to just
covering the thickness of the driven gears (Ref. number 22 and 46 on the parts list (gear case assembly)). DO NOT FILL
TO THE TOP! The drive gear must NOT be covered, as you will create a pressure build-up that will damage seals and
cause grease leakage.
2. Location of additional grease  ttings/zerks.
•Eight  ttings on bearing caps on top of gear case (Ref. number 6 on the parts list (gear case assembly)).
•Lubricate these  ttings with 2 shots of grease every month with Mobilith AW-1 or equivalent.
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 build-up of cement grinding paste occur as this could create an overload on your machine, as well as
more weight to push.
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 9 on gear case assembly) 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 30 on gear case assembly) should be changed a minimum of once a year whether
you use your machine or not.
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.
