AR13HA-R RIDE-ON ROLLER — MAINTENANCE

Forward/Reverse Hydraulic Pressure Test

Park the machine on a solid flat surface and stop the engine. Set the parking brake and block the front drum securely.

1.Check hydraulic oil level by viewing the hydraulic oil sight glass. The hydraulic oil level must be below the top and above the bottom of the sight glass. DO NOT OVERFILL!

2.Adjust engine RPM (3,500 +/- 50 RPM)

3.Let engine run for 5 minutes, this will bring the hydraulic oil operating temperature to a minimum of 135° farenheit.

4.Check and repair all hydraulic leaks.

5.On the manifold block install a 5,000 psi pressure gauge (Figure 34) to the forward pressure quick disconnect test port 2

6.Run engine at full throttle.

7.Move the travel lever to the forward position. MAKE SURE

FRONT AND REAR DRUMS DO NOT SPIN.

8.Read the pressure gauge. The relief pressure (roller drums blocked) will read 2,900 ± 145 psi. Under normal operating conditions this pressure will read 400-600 psi.

9.Return the travel lever to the neutral position and stop the engine.

10.Install the pressure gauge into the reverse quick disconnect port 3 and repeat the above procedures.The relief pressure reading for the reverse test port 3 will be the same (2,900 psi). Again normal operation pressure for the reverse port will be 400-600 psi.

Normal operating pressures are based on the machine traveling on level, firm surface. The operating pressures will increase significantly when traveling uphill.

Vibration Circuit PressureTest

Place the front drum on soil, gravel, or a heavy rubber mat.

DO NOT ACTIVATE VIBRATION FEATURE ON CONCRETE OR HARD SURFACE!

1.On the manifold block install a 5,000 psi pressure gauge to quick disconnect test port 1.

2.Start the engine and run at full throttle.

3.To start the vibration, press the pushbutton switch (vibration control) located on top of the travel lever. Under normal operating conditions this pressure will range between 900-1,500 psi.

Vibration relief pressure is hard to read accurately using this test. It may be

NOTE necessary to disconnect the pressure line to the vibration drive motor. Plug this line and re-test, pressure will be exact relief pressure.DO NOT perform this test for a long period of time — damage could occur.

Steering Pressure Test

1.On the manifold block, install a 5,000 psi pressure gauge into quick disconnect test port 1 (Figure 34).

2.Start the engine and run at full throttle.

3.Turn the steering wheel to the left or right (maximum) and hold.Read the steering relief pressure.The relief pressure reading for the steering test port 1 will be 700 psi. Again, under normal operating conditions, pressure for the steering port will be between 200-400 psi.

If maximum pressure cannot be reached, plug the steering cylinder pressure hoses and re-test. If pressure is correct the steering cylinder is leaking. DO NOT ACTIVATE THE

AR13HA, AR13HAR specifications

The Multiquip AR13HAR and AR13HA are advanced, rugged, and efficient walk-behind rollers designed for various construction and road maintenance applications. These compact rollers are specifically engineered to handle asphalt and soil compaction tasks, making them ideal for both professional contractors and do-it-yourself enthusiasts seeking high-quality performance in compact spaces.

One of the standout features of the Multiquip AR13HAR and AR13HA is their excellent maneuverability. With their tight turning radius, these rollers can easily navigate confined areas, allowing for effective compaction even in challenging sites. This makes them particularly useful for patching, trench work, and other localized applications.

The AR13HAR model is equipped with a reliable water-cooled engine that delivers robust power, ensuring consistent performance throughout the compaction process. The hydraulic system offers smooth operation, allowing operators to adjust the roller's speed and direction with ease. The self-propelled functionality further enhances user experience, catering to various operator preferences.

In terms of compaction capability, both models are fitted with high-frequency vibrating plates that facilitate superior compaction results. The AR13HAR and AR13HA can achieve impressive compaction depths, making them suitable for a wide range of material types. Users can expect consistent and uniform compaction across the working surface, which is essential for building durable pavements and bases.

Another important aspect is their durability. Multiquip has crafted the AR13HAR and AR13HA with robust materials, ensuring that they can withstand the rigors of construction sites. The rollers feature reinforced frames and sturdy drums designed to endure harsh conditions, contributing to a longer lifespan with less maintenance required.

Safety is also a priority in the design of these rollers. They come equipped with essential features like an emergency stop switch and operator protection measures to ensure a secure working environment. Additionally, the ergonomic controls are intuitively positioned, promoting operator comfort and reducing fatigue during extended use.

Overall, the Multiquip AR13HAR and AR13HA represent a perfect fusion of power, agility, and safety in compact roller technology. Their impressive features and robust design make them a reliable choice for professionals looking to enhance efficiency and productivity in their compaction projects. Whether it's a small repair task or a larger construction job, the Multiquip AR13 series can deliver results that meet and exceed expectations.
