DCA-10SPX3 — TOWING

Towing Safety Precautions

CAUTION :CAUTION :

CAUTION :

CAUTION :CAUTION :

Check with your county or state safety
towing regulations department before
towing your generator. Vehicle towing
codes and regulations can vary from state
to state.

To reduce the possibility of an accident while transporting
the generator on public roads, always make sure the trailer
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 are
working properly.

■

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.

■

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.

DCA-10SPX3 — TRAILER-SAFETY GUIDELINES

CAUTION:CAUTION:

CAUTION:

CAUTION:CAUTION:

ALWAYS make sure the trailer is in good
operating condition. Check the tires for
proper inflation and wear. Also check the
wheel lug nuts for proper tightness.

Explanation of Chart:

This section is intended to provide the user with trailer ser­vice and maintenance information. The service and main­tenance 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
damage to the equipment and personal injury.

It is the purpose of this section to cover the major mainte­nance components of the trailer. The following trailer com­ponents 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, hy­draulic, hydraulic-surge and air.

3. GVWR- Gross Vehicle Weight Rating (GVWR), is the
maximum number of pounds the trailer can carry, in­cluding the fuel cell (empty).

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.

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 letters;
2-ply,4-ply,6-ply, etc.

10. Wheel Hub - The wheel hub is connected to the trailer’s
axle.

11. Tire Rim - Tires mounted on a tire rim. The tire rim must
match the size of the tire.

12. Lug Nuts - Used to secure the wheel to the wheel hub.
Always use a torque wrench to tighten down the lug
nuts. See Table 4 and Figure 5 or lug nut tightening and
sequence.

13. Axle - Indicates the maximum weight the axle can sup­port in pounds, and the diameter of the axle expressed
in inches (see Table 3). Please not that some trailers
have a double axle. This will be shown as 2-6000 lbs.,
meaning two axles with a total weight capacity of 6000
pounds.

14. Suspension - Protects the trailer chassis from shocks
transmitted through the wheels. Types of suspension
used are leaf, Q-flex, and air ride.

15. Electrical - Electrical connectors (looms) are provided
with the trailer so the brake lights and turn signals can
be connected to the towing vehicle.

16. Application - Indicates which units can be employed
on a particular trailer.

DCA-10SPX3 — 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.

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.

Suspension

The leaf suspension springs and associated components
(Figure 2) 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.

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 3. 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.

DCA-10SPX3 — INSTALLATION

Outdoor Installation

Install the generator in a location where it is not exposed to
rain or sunshine. Make sure the generator is on a secure
level ground so that it cannot slide or shift around. Also
install the generator in a manner so the exhaust will not be
discharged in the direction of nearby homes.

The installation site must be away from excessive moisture
and dust. All electrical equipment should be protected from
excessive moisture. Failure to do will result in deterioration
of the insulation and will result in short circuits and grounding.

Foreign materials such as dust, sand, lint and abrasive
materials cause excessive wear, to the engine parts and
the alternator parts.

CAUTION :

Pay close attention to ventilation when
operating the generator inside tunnels and
caves. The engine exhaust contains
noxious elements. Engine exhaust must
be routed to a ventilated area.

CAUTION :

Generator Grounding

To prevent electrical shock and possible damage to the
equipment, it is important to provide a good EARTH ground.

Article 250 (Grounding) of the National Electrical Code (NEC)
provides guide lines for proper grounding and specifies that
the cable ground shall be connected to the grounding system
of the building as close to the point of cable entry as
practical.

NEC articles 250-64(b) and 250-66 set the following
grounding requirements:

1. Use one of the following wire types to connect the
generator to earth ground.

a. Copper - 10 AWG (5.3 mm

b. Aluminum - 8 AWG (8.4 mm2) or larger.

An electric shock is apt to happen when
vibrators are used. Pay close attention
to handling when operating vibrators and
always use rubber boots and gloves to
protect the body from electrical shock.

Indoor Installation

Exhaust gases from diesel engines are extremely poisonous.
Whenever an engine is installed indoors the exhaust fumes
must be vented to the outside. The engine should be installed
at least two feet from any outside wall. Using an exhaust
pipe which is too long or too small can cause excessive
back pressure which will cause the engine to overheat.

Eliminate the danger of deadly carbon monoxide gas.
Remember that exhaust fumes from any diesel engine are
very poisonous if discharged in a closed room, but harmless
if allowed to mix with the outside air. If the generator is
installed indoors, you must make provisions from venting
the engine exhaust to the outside of the building.

DO NOT cover ventilation areas on the enclosure. Covering
the ventilation grids will cause the engine to overheat.

the generator and tighten the nut fully. Connect the other
end of the ground cable to earth ground.

3. NEC article 250-52(c) specifies that the earth ground
rod should be buried a minimum of 8 ft. into the ground.

NOTE

When connecting the generator to
any buildings electrical system
ALWAYS consult with a licensed
electrician.

DCA-10SPX3 — MAINTENANCE

General Inspection

Prior to each use, the generator should be cleaned and
inspected for deficiencies. Check for loose, missing or
damaged nuts, bolts or other fasteners. Also check for fuel,
oil, and coolant leaks.

Engine Side (Refer to the Engine Instruction Manual)

Air Cleaner

Every 50 hours: Remove air cleaner element and clean heavy
duty paper element with kerosene, or foam element with
liquid detergent and hot water. Wrap foam element in a cloth
and squeeze dry. For heavy duty paper element, wipe
excess kerosene with towel.

Fuel Addition

Add diesel fuel (the grade may vary according to season
and locations). Always pour through the mesh filter.

Removing Water from the Fuel Tank

After prolonged use, water and other impurities accumulate
in the bottom of the tank. Occasionally remove the drain
cock and drain the contents. During cold weather, the more
empty volume inside the tank, the easier it is for water to
condense. This can be reduced by keeping the tank full as
much as possible.

Air Removal

If air enters the fuel injection system of a diesel engine,
starting becomes impossible. After running out of fuel, or
after disassembling the fuel system, bleed the system
according to the following procedure.

To restart after running out of fuel, turn the switch to the
“ON” position for 15-30 seconds. Try again, if needed. This
unit is equipped with an automatic air bleeding system.

Service Daily

If the engine is operating in very dusty or dry grass
conditions, a clogged air cleaner will result. This can lead to
a loss of power, excessive carbon buildup in the combustion
chamber in high fuel consumption.

Check Oil Level

Check the crankcase oil level prior to each use, or when
the fuel tank is filled. Insufficient oil may cause severe
damage to the engine. Make sure the generator is level.
The oil level must be between the two notches on the dipstick
as shown in Figure 8, page 29.

Replacing Oil Filter



Detach the oil filter cartridge with a filter wrench.



Apply a film of oil to the gasket for the cartridge.



Screw in the cartridge by hand. When the gasket is in
contact with the seal surface, tighten the cartridge one
or two more times by hand.



After the oil cartridge has been replaced, the engine oil
will drop slightly. Run the engine for a while and check
for leaks before adding more oil if needed. Clean
excessive oil from engine.

Replacing Fuel Filter



Replace the fuel filter cartridge with new one every 400
hours or so.



Apply fuel oil thinly over the gasket and hand-tighten
the cartridge into position.



Vent any air.

Flushing Out Radiator and Replacing Coolant



Open both cocks located at the crankcase side and at
the lower part of the radiator and drain coolant. Open
the radiator cap while draining. Remove the overflow
tank and drain.



Check hoses for softening and kinks. Check clamps
for signs of leakage.



Flush the radiator by running clean tap water through
radiator until signs of rust and dirt are removed. DO
NOT clean radiator core with any objects, such as a
screwdriver.



Tighten both cocks and replace the overflow tank.



Replace with coolant (see page 30, Table 5 for mixture).



Close radiator cap tightly.

Cleaning the Fuel Strainer

Clean the fuel strainer if it contains dust or water. Remove
dust or water in the strainer cap and wash it in gasoline.
Securely fasten the fuel strainer cap so that fuel will not
leak. Check the fuel strainer every 200 hours of operation or
once a month.

PAGE 38 — DCA-10SPX3 A.C. GENERATOR— PARTS & OPERATION MANUAL — REV. #2 (01/17/11)

CAUTION :CAUTION :

CAUTION :

CAUTION :CAUTION :

Allow engine to cool when flushing out
radiator. Flushing the radiator while hot
will damage radiator.

DCA-10SPX3 — MAINTENANCE

Generator Storage

For storage of the generator for over 30 days, the following
is required:



Fill the fuel tank completely.



Completely drain the oil from the crankcase and refill
with fresh oil.



Clean all external parts of the generator with a cloth.



Cover the generating set and store in a clean, dry place.
