How to Use RTX-1250-I2 Saw Video Transcript

This video tutorial will show you how to use the RTX-1250-I2 Saw properly.

Texas law requires anyone planning to dig, excavate, or otherwise move earth deeper than 16 inches to call 811 before beginning a project to have underground utilities marked. Rocky Hill Equipment recommends calling 811 prior to any project that involves digging with our equipment, regardless of depth.

To begin with, this is a demonstration of a properly operated RTX-1250-I2 Saw. This machine is designed always to drive forward while cutting and never backward. The backfill blade is at the front of the machine, and the circular cutting blade is at the rear. On the circular blade, different components serve their purpose. You have segments, segment bolts, pockets, and rock bits. Rock bits contact the rock material and break it into smaller pieces, thus making your trench.

Let’s go through the operator control layout.

Taking a seat on the RTX-1250-I2, all controls will be on the operator’s right-hand side. The screen displays battery voltage, hydraulic gauge, fuel and depth gauges, and RPM gauge. Once you activate the wheel saw in the back, a second screen displays a circular saw and creeper speed gauges. At the bottom of the screen, you’ll notice the letter N, indicating that all controls are neutral. We have a handle that controls a few different controls on the machine. This handle controls the backfill blade in the front, allowing it to move up, down, left, and right. By using the switch located in the back of the handle, you can change the angle of the backfill blade. You have the grade control for the front blade below that switch. At the top of the handle, you have three buttons controlling the rear steering. This option is to be used while transporting or maneuvering around objects, not while trenching.

Next, the orange switch allows the operator to control the RPMs. When adjusting RPMs, you’ll see the gauge change on your screen.

Next, we have the H-L button. When transporting, high gear makes it easier and quicker. While trenching the machine needs to be in the low gear, there is an indicator at the top left of the screen showing what gear you are currently on.

Underneath the backfill blade handle, there are three switches and only one is highlighted in green, this switch is what drops and lifts the rear wheel saw. To the right of the switches, starting at the bottom, we have the controls that activate the wheel saw in the rear. To activate, you press the button to the left, highlighted in yellow, then look to the right of your screen, and the letter F should appear. At this point, we are going to turn the knob clockwise to get the wheel in the rear spinning, while you turn the knob on the wheel speed gauge will change simultaneously. Before you drop the wheel to the ground, ensure the speed is 100%. To seize the wheel first, turn the knob counterclockwise slowly till you hit 0%; at this point, press the knob to finalize the shutdown of the wheel.

Moving on to the creeper controls. First, you press the button to the left highlighted in orange, you see an F appear on the left side of the screen next to the creeper speed gauge. Next, you need to turn the knob clockwise, and you will feel the machine advance forward. Once the machine is moving, there is an auto option that allows the machine to keep the creeper’s speed and the wheel in the rear in a safe zone.

Finally, down at the bottom by your feet, we have the foot pedals that move the machine forward and reverse. These will be used while adjusting or transporting the machine, not trenching.

Operating Procedure

Inspect the cutting blade’s rock bits to ensure there are no broken, missing, or loose bits on the blade segments. We always recommend checking your rock bits before, during, and after every use. Look to make sure all my handles controls are in neutral and start the machine. We will now adjust the rock saw to begin cutting our trench. Once adjusted, throttle up your RPMs to the max, press the wheel activation button, and verify that F appears on your screen’s right side. Turn the knob clockwise until you’ve reached 100%. Slowly drop your wheel in the rear. Once you start trenching only drop the wheel a few inches at a time till the depth required, once the depth required is met, press the creeper activation button and verify the F appears on the left side of the screen. Turn the knob clockwise slowly and advance at 1%. Press the auto button; at this point, adjust the speed to stay in the safe zone.

While using this machine, we suggest picking up the saw wheel every 5 feet for the first 20 feet and having a spotter to get a good visual of the rock pits, pockets, and segments. After your first 20 feet, you can pick up the saw blade every 10 or 15 feet, depending on how comfortable you feel with the material you are cutting through. This aims to prevent major damage from occurring; when too many rock pits go missing, you start to damage or break pockets. When finished digging again, put the creeper in neutral, lift the blade, slow the throttle, and put the cutting blade into neutral. Engage the parking brake and turn off the machine.

When you are finished installing your components into your trench, the RTX-1250-I2 Saw also backfills the material to complete the job. This is done with the backfill blade at the front of the machine and using the foot pedal to advance the machine to the desired location. Position the blade close to the final grade level and at a 45-degree angle, facing the blade to the trench. This will force the tailings back into the trench as you creep forward. This machine is not to bulldozer; only push as many of the tailings as you safely can and as many passes as necessary to fill your trench.

Let’s talk about safety.

Always wear the safety seatbelt, as being thrown from the machine in the event of an accident could cause more severe injury than being locked in place under the roll cage. Be aware of the terrain, obstacles, overhead hazards, and other workers near your trenching path. Do not lose focus; trenching can be slow and monotonous, but accidents can happen anytime. Always learn as much as possible about the equipment you’ve rented and its proper operation to complete your job. If you rent equipment for multiple days, please remove the keys from the equipment and store them safely on your job site.

Please return the equipment in the condition it was ready to you clean and full of fuel. If you have any concerns or issues with the equipment, please call us at 210-651-5611 and let us solve those issues for you because we are committed to service at Rocky Hill Equipment Rental.
