2.1 Operator Safety
Familiarity and proper training are required for the safe operation of equipment.
Equipment operated improperly or by untrained personnel can be dangerous. Read
the operating instructions contained in both this manual and the engine manual and
familiarize yourself with the location and proper use of all controls.
2.1.1 ALWAYS disengage and stow the locking bar for the articulated steering joint before
operating the roller. The roller cannot be steered when the locking bar is engaged.
2.1.2 ALWAYS check that all controls are functioning property immediately after start-up.
DO NOT operate the roller unless all controls function properly.
2.1.3 ALWAYS remain aware of changing positions and the movement of other equipment and
personnel on the job site.
2.1.4 ALWAYS remain seated with the seat belt fastened while operating the roller.
2.1.5 ALWAYS remain aware of changing surface conditions and use extra care when operating
over uneven ground, on hills, or over soft or coarse material. The roller could shift or slide
unexpectedly.
2.1.6 ALWAYS use caution when operating near the edges of pits, trenches, or platforms. Check
to be sure that the ground surface is stable enough to support the weight of the roller with the
operator and that there is no danger of the roller sliding, falling, or tipping.
2.1.7 ALWAYS wear protective clothing appropriate to the job site when operating equipment.
Goggles or safety glasses, hearing protection, and safety shoes.
2.1.8 ALWAYS keep hands, feet, and loose clothing away from moving parts of the roller.
2.1.9 ALWAYS read, understand, and follow procedures in the Operator’s Manual before
attempting to operate the equipment.
2.1.10 ALWAYS store the equipment properly when it is not being used. Equipment should be
stored in a clean, dry location out of the reach of children.
2.1.11 ALWAYS operate the roller with all safety devices and guards in place and in working
order.
2.1.12 NEVER allow anyone to operate this equipment without proper training. Individuals
operating equipment must be familiar with the manual and safety functions of this roller.
2.1.13 NEVER touch the engine or muffler while the engine is on or immediately after it has been
turned off. These areas get hot and may cause burns.

6
2.1.14 NEVER use accessories or attachments that are not recommended by Third Coast
Equipment. Damage to equipment and injury to the user may result.
2.1.15 NEVER leave roller running unattended.
2.1.16 NEVER operate the roller with the fuel cap loose or missing.
2.2 Operator Safety While Using Internal Combustion Engines
DANGER
Internal combustion engines present special hazards during operation and fueling.
Read and follow the warning instructions in the engine owner’s manual and the
safety guidelines below. Failure to follow the warnings and safety guidelines could
result in severe injury or death.
2.2.1 DO NOT smoke while operating the roller.
2.2.2 DO NOT smoke while refueling the roller or during any other fuel handling operation.
2.2.3 DO NOT refuel a hot or running engine.
2.2.4 Do NOT refuel the engine near an open flame.
2.2.5 DO NOT spill fuel when refueling the engine. If fuel is spilled during refueling, clean the
surface immediately. Do not operate the roller if fuel or oil leaks exist.
2.2.6 DO NOT run the engine near open flames
2.2.7 DO NOT run the roller indoors or in an enclosed area such as deep trench unless adequate
ventilation is provided. Exhaust gas from the engine contains poisonous carbon monoxide gas;
exposure to carbon monoxide can cause loss of consciousness and may lead to death.
2.2.8 ALWAYS refill the fuel tank in a well-ventilated area.
2.2.9 ALWAYS replace the fuel tank cap after refueling.
2.2.10 ALWAYS keep the area around the muffler free of debris such as leaves, paper, etc. to
reduce risk of an accidental fire.
2.3 Service Safety
WARNING
Poorly maintained equipment can become a safety hazard! For the equipment to
operate safely and properly over a long period of time, periodic maintenance and
occasional repairs are necessary.
2.3.1 DO NOT attempt to clean or service the roller while it is running. Rotating parts can cause
severe injury.

7
2.3.2 DO NOT use gasoline or other types of fuels or flammable solvents to clean parts,
especially in enclosed areas. Fumes from fuels and solvents can become explosive.
2.3.3 DO NOT modify the equipment without the express written approval of the manufacturer.
2.3.4 ALWAYS check all external fasteners at regular intervals.
2.3.5 ALWAYS keep the area around the muffler free of debris such as leaves, paper, cartons,
etc. A hot muffler could ignite the debris and start a fire.
2.3.6 ALWAYS replace worn or damaged components with spare parts recommended by Third
Coast Equipment.
2.3.7 ALWAYS keep the roller clean and all labels legible. Replace any missing or damaged
labels immediately and prior to operation. Labels provide important operating instructions and
warn of dangers and hazards.
2.3.8 ALWAYS switch off the power supply at the battery disconnect before adjusting or
maintaining the electrical equipment.
2.3.9 ALWAYS do Periodic Maintenance as recommended in the Operator’s Manual.

4. OPERATION
4.1 Application
This roller is designed as a lightweight roller to be used in the compaction of sublayer and finish
layers of asphalt on roads, driveways, parking lots, and other types of asphalt-covered surfaces.
Do not use this roller for any other purpose.
4.2 Recommended Fuel
Consult engine Owner’s Manual for complete fuel specifications.
4.3 Before Starting
Before starting the roller, check the following:
oEngine oil level. Hydraulic fluid level. Fuel level.
oFuel lines for leaks or cracks and replace if necessary.
oCondition of air cleaner / filter.
oProper function of all roller controls
oScraper bars - clean and properly adjusted
oEnsure the roller’s travel lever is placed in the neutral position
NOTE:
All fluid levels should be checked with the roller on a level surface.
Ensure that regular maintenance has been carried out.
Ensure that the driver’s platform is clean and dry. Operator’s platform can become slippery when
wet and may result in a fall or injury to the operator.
Always use the steps and handrails when climbing on and off the roller.

4.4 Explanation of Operation Controls
Voltage
The voltage of roller is 12V. If the voltage display is less than 12V, check for proper function of
the battery and circuits.
Water On/Off Switch
Controls the start and stop of water sprinkler pump.
NOTE: Always stop the water sprinkler when roller is not in motion by moving the
Water On/Off Switch to the “Off” position. DO NOT operate the water sprinkler
pump dry as damage to the pump may occur.
Working Lights Switch
Controls the On/Off function of the working lights.
Parking Brake
Holds the roller in place during loading, transportation, or when parked on sloped surfaces. To
engage the parking brake, pull up on the parking brake lever. To release the parking brake, lower
the parking brake lever.
NOTE: It is recommended to always engage the parking brake when the machine is parked or
whenever there is not an operator present in the seat. Always release the parking brake prior to
attempting to move the roller. Failure to do so can result in damage to the brake system or
hydraulic component.
Travel Lever
Controls the forward / reverse travel direction and speed of the roller. Push forward to make the
roller travel forward. Pull the travel lever backward to make the roller travel in a reverse direction.
Vibration Control Button
The button located on the travel lever activates the roller’s vibration
frequency. Toggle the switch on or off to start and stop vibration.
NOTE: ALWAYS turn off the vibration prior to shutting down the machine.
Vibration may resume upon the roller start up if the vibration was not
turned off when last shut down.
