Towing Safety Precautions
CAUTION :
Check with your county or state safety towing regulations department before towing your generator.
To reduce the possibility of an accident while transporting the generator on public roads, always make sure the trailer (Figure 1) that supports the generator and the towing vehicle are in good operating condition and both units are mechanically sound.
The following list of suggestions should be used when towing your generator:
Make sure the hitch and coupling of the towing vehicle are rated equal to, or greater than the trailer "gross vehicle weight rating" (GVWR).
ALWAYS inspect the hitch and coupling for wear. NEVER tow a trailer with defective hitches, couplings, chains etc.
Check the tire air pressure on both the towing vehicle and the trailer. Also check the tire tread wear on both vehicles.
ALWAYS make sure the trailer is equipped with a "Safety Chain".
ALWAYS attach trailer's safety chain to bumper of towing
vehicle.
ALWAYS make sure the vehicle and trailer directional, backup, brake, and trailer lights are connected and working properly.
Remember the maximum speed unless otherwise posted for highway towing is 45 MPH. Recommended off-road towing is not to exceed 10 MPH or less depending on type of terrain.
Place while parked.
Place prevent
Use the trailer's hand winch to adjust the height of the trailer, then insert locking pin to lock wheel stand in place, while parked.
Avoid sudden stops and starts. This can cause skidding, or jackknifing. Smooth, gradual starts and stops will improve gas milage.
Avoid sharp turns to prevent rolling.
Remove wheel stand when transporting.
DO NOT transport generator with fuel in tank.

DCA-500SSK TRAILER SAFETY GUIDELINES
Brakes
If your trailer has a braking system, the brakes should be inspected the first 200 miles of operation. This will allow the brake shoes and drums to seat properly. After the first 200 mile interval, inspect the brakes every 3,000 miles. If driving over rough terrain, inspect the brakes more frequently.
Electric Brakes
Electrically actuated brakes (Figure 2) are similar to hydraulic brakes. The basic difference is that hydraulic brakes are actuated by an electromagnet. Listed below are some of the advantages that electric brakes have over hydraulic brakes:
Brake system can be manually adjusted to provide the
corrected braking capability for varying road and load conditions
Brake system can be modulated to provide more or less
braking force, thus easing the brake load on the towing vehicle
Brake system has very little lag time between the time
the vehicle’s brakes are actuated and the trailers brakes are actuated
Brake system can provide an independent emergency
brake system
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. decrease 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 surface.
Figure 2 displays the major electric brake components that will require inspection and maintenance. Please inspect these components as required.
Electric Brake Adjustment
1. Place the trailer on jack stands. Make sure the jack stands are placed on secure level ground.
2. Check the wheel and drum for free rotation.
3. Remove the adjusting hole cover from the adjusting slot at the bottom brake backing plate.
4. With a screwdriver or standard adjusting tool, rotate the star wheel of the adjuster assembly to expand the brake shoes.
5. Adjust the brake shoes outward until the pressure of the lining against the wheel drum makes the wheel difficult to turn.
6. Rotate the star wheel in the opposite direction until the wheel rotates freely with slight lining drag.
7. Replace the adjusting hole cover and lower the trailer to the ground.
8. Repeat steps 1 through 6 on the remaining brakes.

Hydraulic/Air/Surge Brakes
Hydraulic brakes (Figure 3) should not require any special attention with the exception of routine maintenance such as shoe and lining replacement. These brakes can be adjusted in the same manner as electric brakes. Brake lines should be periodically checked for cracks, kinks, or blockage. Figure 3 below displays the major hydraulic/air/surge brake
components that will require inspection and maintenance. Please inspect these components as required using steps 1 through 6 as referenced in the electric brake adjustments section.

DCA-500SSK TRAILER SAFETY GUIDELINES
Tires/Wheels/Lug Nuts
Tires and wheels are a very important and critical components of the trailer. When specifying or replacing the trailer wheels it is important the wheels, tires, and axle are properly matched.
CAUTION:
DO NOT attempt to repair or modify a wheel. DO NOT install in inner tube to correct a leak through the rim. If the rim is cracked, the air pressure in the inner tube may cause pieces of the rim to explode (break off) with great force
and cause serious eye or bodily injury.
Suspension
The leaf suspension springs and associated components (Figure 4) should be visually inspected every 6,000 miles for
Tire Wear/Inflation
Tire inflation pressure is the most important factor in tire life. Pressure should be checked cold before operation DO NOT bleed air from tires when they are hot. Check inflation pressure weekly during use to insure the maximum tire life and tread wear. Table 2 (Tire Wear Troubleshooting) will help pinpoint the causes and solutions of tire wear problems.
signs of excessive wear, elongation of bolt holes, and loosening of fasteners. Replace all damaged parts (suspension) immediately. Torqued suspension components as detailed in Table 3.
CAUTION:
NOTE
ALWAYS wear safety glasses when removing or installing force fitted parts. Failure to comply may result in serious injury.

Lug Nut Torque Requirements
It is extremely important to apply and maintain proper wheel mounting torque on the trailer. Be sure to use only the fasteners matched to the cone angle of the wheel. Proper procedure for attachment of the wheels is as follows:
1. Start all wheel lug nuts by hand.
2. Torque all lug nuts in sequence. See Figure 5. DO NOT torque the wheel lug nuts all the way down. Tighten each lug nut in 3 separate passes as defined by Table 4.
3. After first road use, retorque all lug nuts in sequence. Check all wheel lug nuts periodically.

Open Delta Excitation System
The DCA-500SSK generator is equipped with the state of the art " system consist of an electrically independent winding wound among stationary windings of the AC output section.
There are four leads: A, B, C and D. During light loads, the power to the from the leads parallel connections of B&C. When loads increase, the AVR switches and accepts power from leads A&D. The output of leads A&D increase proportionally with load. This of adding the voltages to each phase provides better voltage response during heavy loads.
The connections of the AVR to the AC output windings are for sensing only. No power is required from these windings.
The open-delta design provides virtually unlimited excitation current, offering maximum motor starting capabilities. The excitation does not have a " according the demands of the required load.
Engine
The DCA-500SSK is powered by a 4 cycle, water cooled, turbocharged KOMATSU Model SA6D170BE diesel This engine is designed to meet every performance requirement for the generator. Reference Table 7, page 23 for engine specifications.
In keeping with MQ Power's policy of constantly improving its products, the specifications quoted herein are subject to change without prior notice.
