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:
CAUTION :
Towing Safety Precautions
■ 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.
■ The maximum speed unless otherwise posted for highway
towing is 55 MPH. It is not recommended for off-road
towing. However, if necessary, do not exceed 15 MPH
or less depending on type of terrain to prevent damage
to the axles.
■ Place chocked blocks underneath wheel to prevent
rollingrolling

■ 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.
Check with your county or state safety
towing regulations department before
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 towing vehicle and
trailer. Also check the tire tread wear on both vehicles.
■ ALWAYS make sure the trailer is equipped with a "Safety

Explanation of Chart:
This section is intended to provide the user with trailer ser-
vice and maintenance information. The service and mainte-
nance guidelines referenced in this section apply a wide range
of trailers. Remember periodic inspection of the trailer will
ensure safe towing of the equipment and will prevent dam-
age to the equipment and personal injury.
It is the purpose of this section to cover the major mainte-
nance components of the trailer. The following trailer com-
ponents will be discussed in this section:
 Brakes
 Tires
 Lug Nut Torquing
 Suspension
 Electrical
 Brake Troubleshooting Tables
Use the following definitions with reading Table 1.
1. Fuel Cell - Provides an adequate amount of fuel for
the equipment in use. Fuel cells must be empty when
transporting equipment.
2. Braking System - System employed in stopping the
trailer. Typical braking systems are electric, surge, hy-
draulic, hydraulic-surge and air.
3. GVWR- Gross Vehicle Weight Rating (GVWR), is the
maximum number of pounds the trailer can carry, in-
cluding the fuel cell (empty).
DCA-400SSK — TRAILER-SAFETY GUIDELINES
4. Frame Length - This measurement is from the ball
hitch to the rear bumper (reflector).
5. Frame Width - This measurement is from fender to
fender.
6. Jack Stand - Trailer support device with maximum
pound requirement from the tongue of the trailer.
7. Coupler - Type of hitch used on the trailer for towing.
Usually consists of chains and ‘ball’or ‘eye’.
8. Tire Size - Indicates the diameter of the tire in inches
(10,12,14, etc.), and the width in millimeters
(175,185,205, etc.). The tire diameter must match the
diameter of the tire rim.
9. Tire Ply - The tire ply (layers) number is rated in

DCA-400SSK —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 trailer’s 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.

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.
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.
CAUTION:
NOTE
ALWAYS wear safety glasses when removing
or installing force fitted parts. Failure to comply
may result in serious injury.

Figure 4. Major Suspension Components
Suspension
The leaf suspension springs and associated components
(Figure 4) should be visually inspected every 6,000 miles for
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.

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.
NOTE
NEVER use an pneumatic air gun to
tighten wheel lug nuts.
