Remember in order to properly synchronize the tow vehicle’s braking to the trailer’s braking, can only be accomplished by road testing. Brake lockup, grabbiness or harshness is due to lack of synchronization between the tow vehicle and the trailer being towed or under-adjusted brakes.

Before any brake synchronizations adjustments can be made, the trailer brakes should be burnished-in by applying the brakes 20-30 times with approximately a 20 m.p.h. de- crease in speed, e.g. 40 m.p.h. to 20 m.p.h. Allow ample time for brakes to cool between application. This allows the brake shoes to slightly be seated into the brake drum sur- face.

Figure 20 displays the major electric brake components that will require inspection and maintenance. Please inspect these components as required. See Table 12 Electric Brake Troubleshooting.

Figure 20. Electrical Brake Components

Breakaway Battery

This battery supplies the power to operate the trailer brakes if the trailer uncouples from the tow vehicle. Be sure to check, maintain and replace the battery according to the battery manufacturer’ instructions.

Breakaway Switch

This switch causes the breakaway battery to operate the electric brakes if the trailer uncouples from the tow vehicle. The pull cable for the pull pin is connected to the tow vehicle, and the switch is connected to the trailer. To check for proper functioning of the switch, battery and brakes, you must pull the pin from the switch and confirm that the brakes apply to each wheel. You can do this by trying to pull the trailer with the tow vehicle, after pulling the pin. The trailer brakes may not lock, but you will notice that a greater force is needed to pull the trailer.

MAINTENANCE (TRAILER)

WARNING - Breakaway Brake System

If electric breakaway brakes do not operate when trailer is uncoupled from the tow vehicle, death or serious injury can occur.

Check emergency breakaway brake system BEFORE each tow.

The electric brakes that operate in conjunction with the tow vehicle

brakes must be “synchronized”

NOTE so that braking is properly distrib- uted to the tow vehicle brakes and the trailer brakes. For proper op- eration and synchronization, read

and follow the axle/brake and the brake controller manufacturers’ instructions. To make certain an electrically- operatedbraking system will function properly, you must have your dealer inspect the magnets at least once a year, or each 12,000 miles. See the brake manual for wear and cur- rent inspection instructions.

Hydraulic Brack Actuator

The the surge brake actuator (Figure 21) is the mechanism that activates the trailer’s brake system. This actuator changes fluid power into mechanical power. Therefore, the fluid level must be checked frequently to assure that the brakes function properly.

WARNING - Actuator Fluid Level

Failure to maintain proper fluid level in the actuator may result in loss of braking action which could cause severe property damage, injury or death.

The MP200DLTS and MP200DLTE models are particularly noteworthy for their robust design and versatility. Both are equipped with a powerful engine that delivers high centrifugal force, allowing operators to achieve effective compaction on different soil types. Their durable construction ensures longevity, even in demanding environments. The MP200DLTS features a dual-direction capability for increased maneuverability, while the MP200DLTE is designed for heavier-duty tasks and larger areas.

For users looking for a slightly more compact solution, the MP150SDLTE is a standout choice. This model combines portability with power, making it ideal for smaller jobs or confined spaces. It excels in providing precise compaction where larger equipment may struggle, while still maintaining high performance standards.

The P200DLST model offers enhanced features such as a heavy-duty baseplate designed to offer increased stability and excellent surface contact. This contributes to better results when compacting asphalt or granular materials, making it a preferred choice for road construction and repair projects.

Finally, the MP200SDLTE boasts advanced technology that enriches its operational capabilities. With an integrated vibration control system, users can adjust the compaction force on the fly, allowing for tailored performance based on specific job requirements. Its ergonomic handle design enhances user comfort, reducing fatigue during extended use.

Safety is also a priority in these models, with features such as protective guards and emergency stop buttons, ensuring that operators can work confidently. The overall combination of power, versatility, and innovative features makes the Multiquip MP series an essential tool for contractors in both construction and landscaping sectors.

In summary, whether it’s the heavy-duty capabilities of the MP200 series or the compact efficiency of the MP150SDLTE, Multiquip's offerings deliver outstanding performance, making them ideal for various compaction tasks. The robust engineering and thoughtful features provide users with the reliability needed in today’s competitive marketplace.
