Setup Procedures
These machines are meant to be used at or near the
working area and under operator supervision. If
machine must be located out of sight of the operator,
special controls may be required for proper machine
operation and operator safety.
Always locate the trailer in the driest and safest place
possible. Avoid high traffic areas and use flashers and
safety cones. Position the trailer so that the hose can
be pulled directly off of the reel for use.
Avoid areas where water can be sprayed at machine.
Locate the equipment on a solid level area with slopes
for drainage. When operating upon unlevel ground,
position trailer with hitch end at the downhill side.
WARNING: Do not unhitch or operate trailer
unhitched on unlevel ground.
Before using the trailer, make sure there are no
impurities in the incoming water supply. Turn the
water source on for at least 15 seconds, to remove any
possible debris in the water before connecting hose to
water supply.
The inlet screen located inside the filter should be
cleaned before each use. Filter is located behind valve
panel and can be accessed from underneath or by
removing small access panel in control cabinet. To
clean the inlet screen, unscrew cap beneath the filter,

Referencing The Utility Trailer In This
Manual
All references to the trailer or component parts to either
left or right are made with the assumption that you are
standing behind the trailer facing forward. Your left
hand or right hand is the equivalent on the trailer.
Tire Safety
The most common cause of trailer tire failure is under-
inflation. Therefore, it is important that you always
maintain the specified air pressure as indicated by the
tire manufacturer on the tire's side-walls. This informa-
tion can also be found on the tire label or the air
pressure molded on the tire side-wall.
The most important things you can do to maintaining
proper tire pressure are observe all tire and trailer
maximum carrying capacities, avoid road hazards, and
inspect the tires for cuts, slashes and other irregulari-
ties. These practices, along with other care and mainte-
nance, can improve handling, help protect you and
others from avoidable breakdowns and accidents,
improve fuel economy, and increase the life of your
tires.
Make tire safety a regular part of your trailer mainte-
nance routine. The time you spend is minimal
compared to the amount of time, inconvenience, and
potential safety hazards that can occur from a flat tire or
failure.
Basic Tire Maintenance
Properly maintained tires improve the load-carrying
capability of your trailer. You can help avoid flat tires
and tire failures by maintaining proper tire pressure,
observing tire and trailer capacity limits, avoiding road
hazards, and inspecting your tires regularly.
Identifying Your Recommended Tire
Pressure And Maximum Load Carrying
Capacity For Your Trailer
Both the tire placard and the VIN label are permanently
attached on top of the frame of your trailer and have the
required information printed on them. They also list the
maximum load that can be placed on the trailer without
exceeding the load limits of the tires or the trailers other
components. These labels indicate the manufacturer’s
information including:
• Recommended tire size.
• Recommended tire inflation pressure.
• The maximum weight the trailer is designed to
carry.
• Gross vehicle weight rating of the trailer.
• Gross axle weight rating of the trailer.
Understanding Tire Pressure
and Load Limits
Tire inflation pressure is the level of air in the tire that
provides it with the load-carrying capacity and affects
the overall performance of the trailer. The tire inflation
pressure is a number that indicates the amount of air
pressure that is inside the tire. It is measured in pounds
per square inch (PSI). The tire must be inflated to the
air pressure as designated on the labels. Also listed on
the labels is the air pressure in kilo Pascals (kPa),
which is a metric measurement. Tire manufacturers
determine the air pressure to maximize the amount of
weight the tires can safely carry. The proper tire
pressure for your trailer tires is referred to as the
“recommended cold inflation pressure.” It is difficult to
obtain the recommended tire pressure if your tires are
not cold when the reading is taken because the air will
expand when it is warmed by towing down the road,
thus increasing the air pressure inside. If air is added to
a tire that is low the air pressure should never exceed
the recommended pressure.
It is important to check your trailer’s tire pressure at
least once a month for the following reasons:
Most tires will naturally lose air over time.
Tires can lose air suddenly if driven over an object that
punctures or cuts the tire. Sometimes a sharp blow
from a pothole or curb can knock the tire loose from the
rim causing immediate deflation.
Maintaining Proper Tire Pressure
Locate the recommended tire pressure on the trailer's
tire information placard or owner's manual.
Record the tire pressure of all tires. If the tire pressure
is too high in any of the tires, slowly release air by
gently pressing on the tire valve stem with the edge of
your tire gauge until you get the correct pressure.
If the tire pressure is too low, note the difference
between the measured tire pressure and the correct tire
pressure. These “missing” pounds of pressure are what
you will need to add.
Landa ECOS 7000 Operator’s Manual 9.801-316.0 - G

9
Add the missing pounds of air pressure to each tire that
is under inflated.
Check all tires to make sure they have the same air
pressure.
If you have been towing your trailer and think that a tire
is under inflated, fill it to the recommended cold inflation
pressure indicated on your trailer's tire label placard or
the VIN label. You can also check the sidewall of the
tire for a correct tire inflation pressure. Your tire will
have a slightly lower air pressure because the tire is
warm when you are inflating it, but it will be much better
than to continue to tow it with the under inflation it may
have had. Once the trailer has been parked long
enough to allow the tires to cool down, recheck the tire
pressure and add additional air to return the tire
pressure to the recommended level.
Tire Size
To maintain the trailer's carrying capacity and safety,
purchase only the same size tires as what were origi-
nally supplied on the trailer.
Safety Tips
Slow down if you have to go over a pothole or other
object in road.
Do not run over curbs and try not to strike the curb
when parking.

IMPORTANT: Before towing this trailer be sure to
read the instructions and warnings supplied in this
manual. Also read the information supplied with
your tow vehicle so you know and understand it's
limitations.
Never Tow the Trailer Before Checking:
• Coupler and latch assembly show no signs of
wear or damage.
• Coupler hitch and hitch ball are of the same
size.
• Coupler and safety chains are safely secured to
the hitch.
• Check all fasteners for proper tightness.
• Load is securely tied down to the trailer.
• Wheel lug nuts are properly tightened to the
right torque.
• Wheel bearings are properly adjusted and
maintained.
• Load is within the maximum load carrying
capacity of trailer.
• Tires are properly inflated and are road worthy.
• All trailer lighting is working properly.
• Tire pressure and tire condition
• Wheel lugs*
• Bearing lube and tightness
• Hitch
• Safety chains
• 12V running lights
• Distribution and security
• Caster up in travel position
* Check lug nuts for tightness before initial trip, at 10
miles, 25 miles and 50 miles. Recheck every 3 months
or 3000 miles.
NOTE: Checking all of the above steps before every
trip is key for safety.
IMPORTANT: The load must be distributed equally
on the bed of the trailer if possible. Heavy, concen-
trated loads may cause damage or possible failure
of the trailer.
WARNING: Loads place on the trailer must be
securely tied to the trailer. Always use appropriate
tie downs designed to restrict loads from moving
when properly attached. Failure to do so will allow
shifting of the load causing potential trailer failure
and/or loss of the load and personal injury.
This trailer is equipped to meet all applicable federal
safety standards in effect the day of manufacture.
Check local and state requirements regarding any addi-
tional equipment that may be required.
The addition of optional equipment to your trailer may
in- crease the total weight of your trailer package to
where it now exceeds the maximum load carrying
capacity of the trailer.
Landa ECOS 7000 Operator’s Manual 9.801-316.0 - G

Tow Vehicles
WARNING: Serious injury or property damage can
result if the total weight of your loaded trailer
exceeds the capacity of the hitch and/or your tow
vehicle.
It is very important that you know and understand the
towing capabilities of your tow vehicle. This is espe-
cially true with the braking abilities of the tow vehicle.
You should check with your authorized dealer to see
what the capabilities are for the total towing load and
the maximum allowable tongue weight for the vehicle
you plan on using for towing.
It is also important that the lighting system in the tow
vehicle has sufficient capacity support the additional
load the trailer lighting will add to the system. A heavy
duty flasher may be required to make your turn signals
function properly.
Trailer Ball & Couplers
WARNING: Failure to properly engage the hitch ball
in the coupler ball socket and securely lock the
coupler latch mechanism can cause the trailer to
become detached from the tow vehicle while trav-
eling, which may cause serious injury or property
damage.
Ball diameter for which rating (GVWR) shall not exceed
the gross trailer weight marked on the trailer coupler.
The hitch balls have the rated load they are capable of
towing stamped Into the top of the ball.
Make sure the ball that you use to tow your trailer has
the same capacity rating as the coupler.
Do not use a different size ball than the size the coupler
is designed to use.
Before Towing
Check mounting bracket hardware for wear and proper
tightness. Replace bent, broken, or worn hardware.
Tighten hardware to 75-94 ft. lbs. Use only the
hardware provided with the Trailer. If replacement
hardware is needed, order replacement kit 8.924-
356.0.
Make sure that the trailer safety chains are properly
connected to the towing vehicle and trailer according to
SAE J684. See Safety Chain information in your
manual.
Make sure that all trailer lighting is hooked up and
working properly.
Warning: Failure to follow all installation
instructions could result in coupler failure.
Variable Height Bracket
Coupler operation must not be impaired in any way. Do
not use if coupler operation is impaired.
Bolting Instructions
Align holes in coupler and mounting bracket.
NOTE: Coupler must be secured to mounting
bracket using two sets of holes in the mounting
bracket. Insert two (2) 5/8”x4.5”, grade 5 bolts
through desired mounting bracket holes and coupler.
For each bolt, Place one (1) washer at the bolt head
side and another at the bolt thread side before
assembling the nuts. Tighten lock nuts to 90-96 ft.
lbs. After installation, ensure coupler operation is not
impaired in any way. Do not use if coupler operation
is impaired. The hardware provided with the trailer
has a self-lubricating coating which is taken into
account for the tightening torque above, and is lower
than standard hardware and also is more consistent
with re-torque specifications to first-torque than
standard hardware. Order replacements with the
8.924-356.0 replacement kit, or consult your
hardware vendor for applicable, higher, torques for
the application.

1. Block trailer wheels.
2. Open locking lever. While holding locking lever fully
open, raise trailer off of hitch ball.
NOTE: A 5/16” diameter pin can be used to hold the
locking lever open.
Hitch Coupler Troubleshooting
If the coupler becomes damaged it must be repaired or
replaced before towing. When the coupler is placed on
the ball, the latch should close firmly. Keep the latch
mechanism lightly oiled and clean. Items to check for
are as follows:
1. Latch does not grasp ball securely:
• Check the ball size. Make sure the ball and
coupler are the same size.
2. Latch does not snap into full latch position:
• Check adjustment. Latch mechanism may be
too tight.
• Check to see that the coupler housing has not
been damaged, keeping the ball hitch from
fitting completely into the housing as designed.
3. Keep the tongue blocked up when not in use so the
coupler and mechanism are not in the ground
being exposed to dirt and moisture.
4. Apply a small amount of an automotive grease to
the ball before hitching coupler to prevent wear of
the two parts during towing.
5. Make sure the latch safety pin is in position before
towing.
Coupler & Ball Engagement
If the coupler and towing ball resist attempts to make
engagement, do not force latch assembly. Instead,
check the ball diameter to verify that it conforms to
Society of Automotive Engineers (SAE) specifications.
Standard two-inch diameter ball should be within the
limits of 2.000-inches to 1.970-inches. Balls larger than
2.000- inches will not readily fit the coupler. A two-piece
coupler ball is not recommended.
If the coupler becomes damaged it must be repaired or
replaced before towing. When the coupler is placed on
the ball, the latch should close firmly. Keep the latch
mechanism lightly oiled and clean.
Improper engagement of the coupler and ball can
cause damage if the vehicles separate in transit, thus,
caution must be exercised to insure a secure hook-up.
Lower the coupler onto the ball with the coupler latch in
the vertical position. Continue to lower the trailer
tongue until the jack clears the ground, then flip the
coupler latch to its locked (horizontal) position. At this
point visually observe that the ball is fully engaged in
the ball hitch. An even better check to make sure the
two are fully engaged is to raise the tongue of the trailer
again using the jack. Raise until the ball hitch connec-
tion starts to raise the rear of the tow vehicle. If the
connection was not properly made, the ball and socket
will separate as the tongue of the trailer is raised.

Safety Chains
Listed in the chart below are the different class sizes of
safety chains and the rated load each chain must be
capable of withstanding. Your trailer is equipped with
safety chains that meet the requirements of D.O.T
Regulation 393.70.
WARNING: Failure to properly attach safety chains
between the trailer and tow vehicle can result in a
runaway trailer.
WARNING: To avoid accidents, before trailering:
• Hitch only to ball size marked on coupling.
• Ball clamp must capture ball and lever or hand
wheel is fully clamped.
• Cross safety chains under coupling.
• Allow only enough slack for turns.
Bottom View
The safety chains on your trailer are an added
insurance that it will not become detached from the tow
vehicle. All safety chains are provided with an added
clasp to keep them from becoming accidentally
detached from the tow vehicle. Your trailer hitch on the
tow vehicle should have two attaching holes or rings for
attaching the safety chains, preferably one on each
side of the ball hitch. Crisscross the chains under the
tongue, the chain on the left side of the trailer tongue
attached to the right side of the ball hitch, the chain on
the right side of the trailer tongue attached to the left
side of the ball hitch.
This prevents the trailer tongue from dropping to the
road should the coupler or ball hitch fail. The chains
should be rigged as tight as possible with just enough
slack to allow tight turns to be made. This can be
accomplished by twisting the chain hook in a clockwise
or counterclockwise direction thus twisting the link
spacing and making the chain shorter. Also by keeping
your chains as short as possible you prevent them from
dragging on the road and wearing the chain links. If for
any reason you find it necessary to replace a safety
chain, use only original equipment.
Load-Carrying Capacity
Located on the front left-hand side of the frame, (either
the inside or the outside) is the VIN (Vehicle Identifica-
tion Number) tag. It will show the GVWR (Gross
Vehicle Weight Rating) which is the maximum load that
can be applied to the tires on the trailer. The GVWR
and the carrying capacity of the trailer are based on the
tire size installed on the trailer.
The GVWR is the maximum carrying capacity of the
trailer with its respective tires. It may not necessarily
equal the total GVWR of the trailer less the empty
weight of the trailer because there may be another
controlling factor such as frame strength that reduces
the carrying capacity to what is listed on the VIN tag.
The tire label will list the tire size that was installed on
the trailer as original equipment when it was sold to
you, the consumer. It also lists the maximum carrying
capacity of the trailer.

IMPORTANT: The total weight of the load must
never exceed the weight of cargo listed on the tire
label and/or the maximum load carrying capacity
listed on the VIN tag on your trailer. The GVWR
(Gross Vehicle Weight Rating) listed is the
maximum total weight of the trailer with accesso-
ries and all cargo allowable to be carried on the
tires that are installed on the trailer.
WARNING: Fishtailing caused from improper
tongue weight on the tow vehicle hitch ball can
cause loss of control of the tow vehicle and
resulting serious injury or property damage.
CAUTION: The maximum load applied to the trailer
must never exceed the carrying capacity of the
trailer as stated on the VIN label and/or the tire
placard. Doing so may cause failure of one or more
component parts of the trailer causing potential
damage to the trailer and/ or a potential accident.
All concentrated loads must be spread over as
large an area as possible to eliminate potential
damage to the decking.
Shown below is an example of the tire label that is
placed on your trailer showing the items just discussed
above. Once you have familiarized yourself with the
information supplied on the example tire label and VIN
tag, check the tire size and capacity of your trailer as
shown on the VIN tag on your trailer.
Proper Weight Distribution & Tongue
Weight
Ensuring that your trailer has the proper GVWR is very
important. Once that has been established and you
have the load on the trailer it is equally important that
you have proper weight distribution.
Tongue Weight
The tongue weight on your trailer is 10%-15% of the
total weight of the trailer and all the cargo that it is
carrying. This is the amount of weight that is then trans-
ferred to the tow vehicle through the ball hitch.
Example: The total weight of the trailer with load is
6500 pounds. The tongue weight should not be less
than 650 pounds (10%).
Too light of tongue weight can cause the trailer to “fish-
tail” (sway Weight Rating) as you travel down the
highway. This creates excessive strains on the tow
vehicle, hitch and on the trailer itself. It can very easily
lead to an accident.
To adjust for too light of a tongue weight the load must
be shifted forward with respect to the axle. This will
increase the weight that is transferred to the tongue.
Adjustments should be made until the tongue weight
falls within 10% -15% recommended range. Likewise, if
you have too much tongue weight adjust the weight
backwards with respect to the axle until the tongue
weight falls in the recommended range
Tow vehicles vary on how much tongue weight they
can support for proper towing.
Tire Pressure
Proper air pressure for your tires is printed on the
sidewall. Check pressure while tires are cold. Do not
raise or lower pressure to meet load. Pressure other
than recommended pressure will lead to excessive tire
wear or tire failure. Balancing recommended.
Wheels
Check wheels for hole elongation or “out of round”. This
condition can be caused by lug nuts not being tight or
being too tight. Trailer wheels can be damaged by
chuck holes or curb jumping. You may not be aware of
the road shock to the wheels without periodic checks.
Replace any wheel that is bent. Replace any wheel if
you see elongation of the bolt holes.
Wheel Lugs
Wheel lug nuts must be tightened with a torque wrench.
Refer to the chart below for proper torque.
1. Start all bolts or nuts by
hand to prevent cross
threading.
2. Tighten bolts or nuts
following sequence at
right.
3. The tightening of the
fasteners should be done in stages. Following the
recommended sequence, tighten fasteners per
wheel torque chart below.
4. Wheel nuts/bolts should be torqued before first
road use and after each wheel removal. Check and
re-torque after the first 10 miles, 25 miles and
again at 50 miles. Check periodically thereafter.
Landa ECOS 7000 Operator’s Manual 9.801-316.0 - G

Wheel Torque Requirements
Ball Coupler Hitches
Coupler assembly includes a latch lever and latch lever
safety pin or hitch pin. Be sure the latch lever is locked
and the pin properly secured before moving your trailer.
The pin can be engaged fully only if ball is properly
seated in the coupler.
Tires
Before mounting tires onto wheels make certain that
the rim size and contour is approved for the tire as
shown in the Tire and Rim Association Yearbook or the
tire manufacturer’s catalog. Also make sure the tire will
carry the rated load. If the load is not equal on all tires
due to trailer weight distribution, use the tire rated for
the heaviest wheel position.
NOTE: The capacity rating molded into the sidewall
of the tire is not always the proper rating for the tire if
used in a trailer application. Use the following
guideline:
1. LT and ST tires: use the capacity rating molded
into the tire.
2. Passenger Car Tires: Use the capacity rating
molded into the tire sidewall divided by 1.10.
Use tire mounting procedures as outlined by the
Rubber Manufacturer’s Association or the tire manufac-
turers.
NOTE: Tire wear should be checked frequently
because once a wear pattern becomes firmly
established in a tire it is difficult to stop, even if the
underlying cause is corrected.

Breakaway Switch &
D.O.T. Wet Cell Battery
After hitching to the tow vehicle, pull the safety pin on
the breakaway switch. Check to see if system is opera-
tional. Push safety pin back in to its original position.
Check battery fluid level every 60-90 days. Remove
cover. There are two fill caps. Refill with distilled water
only.
Breakaway Switch
Mounted on an A-Frame
Attach breakaway switch cable securely in a straight
line to the tow vehicle. Locate attachments so little
“slack” is left in the cable, but enough slack to allow for
turning without disengaging the pin. The cable will
activate brakes the instant a trailer becomes disen-
gaged. Brake adjustment is critical to stopping a disen-
gaged trailer.
Check Breakaway System
& Brakes Before Each Trip
1. Disconnect 12V plug from tow vehicle.
2. Pull breakaway pin.
3. While pin is pulled, move tow vehicle forward.
Brake should be on and wheels locked.
4. Replace pin and secure to tow vehicle. Do not loop
over hitch ball.
5. Plug 12V connector into tow vehicle receptacle.
6. Test brakes with brake controller.
NOTE: When disconnecting trailer from tow vehicle,
make sure to replace safety pin.
Landa ECOS 7000 Operator’s Manual 9.801-316.0 - G

Brakes
Your trailer is equipped with one of several brake type
options.
Complete service and repair information for each
available type brake is found in the Axle Break Service
Manual that is furnished with your trailer,
NOTE: It is important to strictly adhere to the axle break
instructions for brake service and repair. In this way, you
are protecting the validity of all applicable warranties.
Burnishing the Brakes
Brakes on a new trailer may tend to “grab” or pulsate. This
is normal. To correct the situation, pull the trailer with the
trailer brake control slightly engaged a short distance
(about 1000 ft or until trailer does not grab or pull to one
side anymore). This action smooths down the brake
bands.
NOTE: Do not lock up the wheels.
Brake Adjustment
Brakes should be adjusted (1) after the first 200 miles
of operation after the brake shoes and drums have
“seated”, (2) at 3000 mile intervals and (3) as use and
performance require. The brakes should be adjusted in
the following manner:
1. Jack up trailer and secure on adequate capacity
jack stands. Check that wheel and drum rotate
freely.
2. Remove adjusting hole cover from adjusting slot on
bottom of brake backing plate.
3. With screwdriver or standard adjusting tool, rotate
the starwheel of the adjuster assembly to expand
the brake shoes. Adjust the brake shoes out until
the pressure of the linings against the drum makes
the wheel very difficult to turn.
NOTE: With drop spindle axles, a modified adjusting
tool with about an 80 degree angle should be used.
4. Then rotate starwheel in opposite direction until
wheel turns freely with slight lining drag.
5. Replace the adjusting hole cover and lower wheel
to ground.
6. Repeat above procedure on all brakes.
CAUTION: Never crawl under your trailer
unless it is resting on properly placed jack
stands.
Do not lift or place supports on any part of the suspen-
sion system.
Brake Cleaning & Inspection
Your trailer brakes must be inspected and serviced at
yearly intervals or more often as use and performance
require. Magnets and shoes must be changed when
they become worn or scored thereby preventing inade-
quate vehicle braking.
Clean the backing plate, magnet arm, magnet and
brake shoes. Make certain that all the parts removed
are replaced in the same brake and drum assembly.
Inspect the magnet arm for any loose or worn parts.
Check shoe return springs, hold down springs and
adjuster springs for stretch or deformation and replace
if required.
CAUTION: Asbestos Dust Hazard. Since
some brake shoe friction materials contain
asbestos, certain precautions need to be
taken when servicing brakes:
1. Avoid creating or breathing dust.
2. Avoid machining, filing or grinding the brake
linings.
3. Do not use compressed air or dry brushing for
cleaning. (Dust can be removed with a damp
brush).
Reporting Safety Defects
If you believe that your trailer has a defect which could cause
a crash or could cause injury or death, you should immedi-
ately inform the National Highway Traffic Safety Administra-
tion (NHTSA) in addition to notifying Landa.
If NHTSA receives similar complaints, it may open an investi-
gation, and if it finds that a safety defect exists in a group of
trailers, it may order a recall and remedy campaign. However,
NHTSA cannot become involved in individual problems
between you, your dealer or Landa.
To contact NHTSA, you may either call the Auto Safety
Hotline toll-free at 1-888-327-4236 (or 202-366-4000 in
Washington, DC area) (TTY: 1-800-424-9153) or write to:

Trailer Storage Preparation
If your trailer is to be stored for an extended period of
time or over the winter, it is important that the trailer be
prepared properly.
1. Remove the emergency breakaway battery and
store inside, out of the weather. Charge the battery
at least every 90 days.
2. Jack up the trailer and place jack stands under
trailer frame so that the weight will be off the tires.
Never jack up or place jack stands on the axle tube
or on the equalizers.
3. Lubricate mechanical moving parts that are
exposed to weather, such as the hitch and suspen-
sion parts.
NOTE: On oil lubricated hubs the upper part of the
roller bearings are not immersed in oil and are subject
to potential corrosion. For maximum bearing life it is
recommended that you revolve your wheels
periodically (every 2-3 weeks) during periods of
prolonged storage.
After Prolonged Storage — Inspection Procedures
Before removing trailer from jack stands:
1. Remove all wheels and hubs or brake drums. Note
which spindle and brake that the drum was
removed from so that it can be reinstalled in the
same location.
2. Inspect suspension for wear.
3. Check tightness of hanger bolt, shackle bolt and U-
bolt nuts per recommended torque values.
4. Check brake linings, brake drums and armature
faces for excessive wear or scoring.
5. Check brake magnets with an ohmmeter. The
magnets should check 3.2 ohms. If shorted or worn
excessively, replace.
6. Lubricate all brake moving parts using a high
temperature brake lubricant. (Lubriplate or equiva-
lent).
CAUTION: Do not get grease or oil on brake linings
or magnet face.
7. Remove any rust from braking surface and
armature surface of drums with fine emery paper or
crocus cloth. Protect bearings from contamination
while so doing.
8. Inspect oil or grease seals for wear or nicks.
Replace if necessary.
9. Lubricate hub bearings. Refer to procedure in
manual.
10. Reinstall hubs and adjust bearing per instructions
in manual.
