CHAPTER

Introduction 1

Thank you for choosing from the

Trimble family of precision pipe

lasers. You’ve just made a wise

investment in field-proven products

made by Trimble, the world’s

leading manufacturer of laser-

based leveling, alignment, and

grade-control systems.

The pipe laser is an easy-to-use

tool that provides underground

contractors line, elevation, and

grade control for installing storm,

sanitary, or other gravity-flow pipe.

This system can also be used for

tunneling, boring, pipe alignment,

or any other application requiring

line, elevation, and grade control.

The pipe laser projects a highly

visible red beam of laser light in a

direction at a predetermined

(grade) for the alignment of

gravity-flow pipe. The laser light is

intercepted by a target. To align the

pipe, you need to position it so that

the pipe laser’s beam is centered in

the target.

CHAPTER

Applications

and Setups 5

This chapter describes three

fundamentals for using the Model

DG511/711 to install gravity flow

pipe; they are Grade, Elevation,

and Line, otherwise known as

G-E-L.

To install gravity flow pipe, the

pipe is set to a percentage of

Grade that has been determined by

some engineered plans. The gravity

flow pipe is designed to be set to

some engineered Elevation.

Finally, the gravity flow pipe will

be installed between two designed

points, therefore defining Line.

5 Applications and Setups

30 DG711 and DG511 Pipe Laser User Guide

The process for setting up the

Model DG511/711 remains the

same. The laser beam shall be

sloped to match the plans. The

Elevation of the pipe or cut to

invert is given from the plans at

which the laser shall be used to

control that elevation, and finally

set the laser on Line to match the

orientation of the pipe run.

After all have been set, installing

pipe is accomplished by inserting a

laser target into new pipe sections

and then aligning the pipe until the

laser targets’ bull’s-eye is centered

on the beam.

Grade 5.1

Grade establishes the slope of the

pipe and is generally displayed in

percent (%). A rise of 1 m (1ft)

over a run of 100 m (100 ft ) equals

1.00%.

After setting Grade into the unit,

the laser automatically slopes the

beam to match the slope of the pipe

and maintains its slope if disturbed.

Note – Some engineering plans list

the pipe’s grade on a per foot or

per meter basis. Before using your

Model DG511/711, transfer the

engineered slope information into

the Laser according to the Grade

Display Mode feature. Consult

your salesman or service personnel

for Grade Display Mode

configuration.

Elevation 5.2

Depending on the application and

jobsite conditions, you can set the

laser to an elevation that matches

the centerline of the pipe, at some

distance above the pipe’s invert, or

set it over the top of the pipe.

Applications and Setups 5

DG711 and DG511 Pipe Laser User Guide 31

When setting the laser, a surveyed

manhole grade hub must be

available to set the laser at the

proper elevation and the pipe will

be installed at the correct elevation.

Line 5.3

Line ensures proper direction of

the pipe run between manholes

according to the engineered plans.

Once Grade, Elevation, and Line

are set, the laser will be projected

at the proper grade, elevation, and

line for the pipe run. After a little

practice, it normally takes about 5

minutes to set up the laser and start

laying pipe.

Setup, Step-by-

Step 5.4

Set Grade 5.4.1

1Press the positive or negative

grade button to set the Laser at the

correct grade as determined by the

engineered plans.

list the pipe rise/fall on a per foot

or per meter basis. To ensure that

the correct grade display format is

entered into your DG511/711, see

Setting Line with the

Line Set/Check Featu

re 5.4.10

The Line Set / Check feature,

available with the DG711, can be

used to align the beam to a forward

grade hub by moving the laser to

its maximum leveling limit then

returning it to the original grade

setting. Line Set/Check is

beneficial for setting line if a

manhole mount or transit is not

available.

Note – Before using Line

Set/Check, the Laser must be

accurately positioned for cross-

axis roll to ensure that the laser

beam will track plumb. Consult

your salesman or service personnel

to activate the Line Set/Check

feature.

6Transit Alignment – You may

position your transit over the

laser’s bull’s-eye target in one of

the following methods:

aUse the Laser Plummet and

if your transit is equipped with

an optical plummet, adjust the

horizontal arm to position the

transit’s optical plummet over

the lasers’ bull’s-eye target.

bPlumb Bob: If your transit

does not have an optical

plummet, suspend a plumb bob

from the transit, and align it

over the lasers’ bull’s-eye

target.

7After rough positioning the

transit over the bull’s-eye target,

use the transit's leveling base to

accurately adjust the transit to the

bull’s-eye target.

8Once the transit is set over the

lasers’ bull’s-eye target, sight the

transit on the centerline of the next

manhole and lock the scope on

The laser can be set on a tripod or

mounting plate above the

excavation on the pipe itself. A

laser target is mounted on a pole

and is adjusted to give the correct

distance from the beam to the pipe

invert. For accurate line control, a

level vial can be attached to the

pole to ensure that the target is held

vertically. This is an excellent

setup for shallow cuts for trenches

where water is present.

Pipe Targets 6.4

The correct target you use depends on the elevation of the laser beam above

the pipe invert and your personal preference.

Through the Pipe Applications 6.4.1

For pipes with a diameter of 500 mm (21 inches) or less, the laser beam is

normally projected on the centerline of the pipe. When the target is

calibrated to the pipe’s diameter, the target may be used in any orientation

in the pipe to maintain the target’s bull’s-eye on center with the pipe.

When the laser is set above the flow-line other than the pipe’s centerline,

the target must be leveled in the pipe. If the target is not level, the pipe may

be placed off line or grade.

Pipe Diameter Application Recommended Pipe Target

150 – 300 mm (6 – 12 inches) 956 Target w/small Pipe Target

CHAPTER

Refraction 7

1Refraction is the bending of

light at the interface of two

substances caused by a difference

in the speed of light. Shooting a

laser beam through a pipe having

gas and varying temperatures can

be compared to shining a flashlight

beam into a pool of water and

seeing the light bend.

2Refraction of the laser is

preceded by what appears to be a

flaming of the laser spot at the

edges. When this occurs, it is time

to mix the air within the pipe by

some external means such as a

blower. This occurs on sunny days

when a hot pipe is placed in a cool

ditch. The pipe bottom cools first

and the warmer air in the upper

half of the pipe causes the laser

beam to refract down towards the

cooler air.

3Solvent fumes can also cause

refraction from the glue used at

joints, or on very cold days when a

cold pipe is placed in a warm

trench.

4Refraction is a small diameter

pipe problem. When small

diameter pipe is set, it is

recommended to place the hot-sun-

baked side of the pipe down in the

trench so that it will cool faster

against the earth. This helps create

temperature stability in the pipe.

5Generally, refraction of the

laser beam occurs at the last four or

five joints of the pipe. This is

because the last few sun-baked

7 Refraction

68 DG711 and DG511 Pipe Laser User Guide

joints of the pipe have not had a

chance to cool in the shade of, and

against the earth of the trench.

6If possible, always back-fill the

pipe as you go. The earth is a great

temperature stabilizer as it

surrounds the pipe. The earth tends

to stabilize the temperature of the

pipe and the air inside. Use of a

blower in conjunction with back-

filling accelerates temperature

stabilization. Always back-fill

immediately unless the jobsite

condition makes it impossible.

7To fully minimize the effects of

refraction, it is advisable to use a

blower after the pipe run exceeds

15 m (50 ft). Operate the blower at

a speed that minimizes the effects

of refraction. As the pipe length

increases, increase the speed of the

blower.

8When using a blower, make

sure it is taking in fresh air through

the intake. On the discharge end,

the nozzle should be angled to

bounce the air off the side of the

pipe thereby creating a spiral or

corkscrew effect.

9If possible, mount the nozzle on

the side of the pipe or in the invert.

Avoid attaching the nozzle at the

top of the pipe unless there is no

other choice, as this will push the

warmer gas through the pipe. If a

strong wind is blowing down the

pipe and fighting the blower, it may

not be needed.

10 In large diameter pipe, 45 cm

(18 inches ) and larger, it is better

to position the blower nozzle off

the invert below the laminar

surface of the gas. If this is

insufficient, three alternatives are

possible. Use two electric blowers,

a Homelite Model III-B (or

equivalent) gas driven blower or a

short blast of air from an air

compressor, to clean out the line.

Nozzle

Refraction 7

DG711 and DG511 Pipe Laser User Guide 69

11 If the beam still can not be

controlled, have your backhoe

excavate five buckets full and then

one or two empty buckets as if it

were bailing water. The blower is

pushing heavy fumes in the pipe

that can not get out of the trench

without someone’s help. Cast the

empty bucket on the low side of the

surface or on the downwind side of

the cut.

12 Another solution is to have a

Homelite III-B blower (or

equivalent) at the cut end of the

trench pulling these fumes from the

cut as the electric blower blows

them out of the pipe. This method

does not tie up production and gets

the job done more efficiently.

13 In summary, if all of the above

fail to solve this problem, use the

laser in an over-the-top setup.

Model 929 Blower

Operating

Instructions 7.1

1Use a separate 12-volt

automotive battery to power the

blower.

2Point the nozzle into the pipe to

create a corkscrew effect. This is

the most effective way to create

temperature stabilization.

3Ensure the air intake is not

blocked and the 929 is not set in

water. The support handle/cord

wrap bracket is on the opposite

side of the air intake. This handle

can hook over a manhole step to

keep the unit out of water in the

pipe.

7 Refraction

70 DG711 and DG511 Pipe Laser User Guide

4Start the blower with the first

section of pipe. Use the table on

the blower to determine the blower

speed from the length and size of

pipe being installed. Although very

unlikely, be aware too much air can

also cause refraction.

Checking the Calibration 9.1

76 DG711 and DG511 Pipe Laser User Guide

Checking the calibration of your

pipe laser is easy. All you need is

an engineer’s rule and your pipe

laser:

1Select a level road, parking lot

or field whose rise is not more than

10 cm in 30 m (4 inches in 100 ft).

2Choose two points (A and B)

about 30 m (100 ft) apart. The

distance does not have to be

measured, but the points must be

found, so mark them well.

3Set up the pipe laser just behind

the lowest point and rough level.

4Turn on the pipe laser and let it

warm up for about 10 minutes.

5Set the grade counter to

0.000%.

6Aim the laser beam so that it

passes over points A and B. Allow

the pipe laser to self-level.

7Accurately measure the

elevation to the center of the beam

at point A and record the elevation

as A1 in a table like the one shown

below:

8Accurately measure the

elevation to the center of the beam

at point B and record the elevation

as B1.

9Move the pipe laser behind

point B and aim the laser beam so

that it passes over points A and B.

Allow the pipe laser to self-level.

10 Accurately measure the

elevation to the center of the beam

at point B and record the elevation

as B2.

11 Accurately measure the

elevation to the center of the beam

at point A and record the elevation

as A2.

Calibration 9

DG711 and DG511 Pipe Laser User Guide 77

12 Subtract the A1 and B1

elevation readings from A2 and B2

elevation readings.

Note – Your laser is in calibration

if the difference between A2 – A1

equals B2 – B1.

Note – If A2 – A1 is greater than

B2 – B1, the laser beam is shooting

high and you should readjust the

laser’s calibration bringing the

beam to level.

Note – If A2 – A1 is less than B2 –

B1, the laser beam is shooting low

and you should readjust the laser’s

calibration bringing the beam to

level.

Note – If the error is greater than

6.4 mm/30 m (0.02 ft in 100 ft),

return the pipe laser to an

authorized Trimble service center.

Adjusting the

Calibration 9.2

The goal to adjusting the pipe

laser’s calibration is to make the

beam level, half the distance of the

total error. This will be the true

calibration point of the unit.

1Enter the Calibration feature

option by simultaneously pressing

the power, decrease, and

backlight/lock buttons (buttons 1,

4, 6).

2Press the backlighting/lock

button to enter the selection.

Note – To change the displayed

calibration constants when you are

in the Level Cal. mode, use the left-

or right-line control button

Note – For every 10 digits

changed, the beam’s elevation

changes 1.6 mm/30 m (1/16 inch

per 100 ft).

Note – The maximum adjustable

range is ±120 digits or ±19 mm/30

m (±3/4 inch per 100 ft ).

3When the pipe laser is

calibrated, press the backlight/lock

button to set the calibration.

Note – The laser beam will move to

the new calibration point AFTER

the calibration option is exited and

the normal grade display returns.

The laser will NOT move during

calibration. Verify that the

calibration is correct AFTER

exiting the calibration menu.

Grade Check 9.3

After the first 8–15 m (25–50 ft) of

pipe has been laid, it is

recommended that you make a

grade check to ensure that the setup

is correct, and that the system is

properly operating.

The illustration shows a method for

checking grade.

1Using a transit level, or an

automatic level and a grade rod,

take a reading at the beginning of

the pipe “A”.

2Using the same instruments,

obtain a level reading at the end of

the pipe “B”.

3The difference between the

readings equals the rise over the

run.

4In terms of % of grade, rise

divided by the run times 100 equals

the percent of grade.

Note – The user of this equipment

is expected to follow all operating

instructions and make periodic

checks on the proper grade,

elevation, and line of the pipe as it

is being laid. Trimble or its

representatives assumes no

responsibility for improperly laid

pipe.

Maintenance

and Care 10

You will get years of service from

the leveling system by following

the maintenance and care

recommendations in this manual.

Carry the laser in its moisture-

resistant, field-tested carrying case

to safely move the laser from one

job to another.

However well the product is

designed, mishaps do occur. The

most common problems associated

with these are covered in the

following areas.

Storage 10.1

CWarning – Do not store

the laser in a wet carrying

case. If the case gets wet,

open it and let it dry before

storing the laser.

CWarning – Remove the

batteries from the laser

when storing it for more

than 30 days.

10 Maintenance and Care

82 DG711 and DG511 Pipe Laser User Guide

Battery Disposal 10.2

Some countries, states, and local

areas have regulations regarding

the disposal of rechargeable

batteries. Be sure that replaced

batteries are disposed of properly.

System Cleaning 10.3

Use only a good-quality glass

cleaner and a soft cloth to clean all

external optical components. A dry

cloth used on the laser’s/IR remote

control’s optical components or

displays could scratch or damage

these surfaces.

Blow off any loose debris before

cleaning any surfaces to prevent

scratching of optical surfaces.

Monthly, wipe off with a moist,

clean cloth any dust or dirt from

the laser’s outer surface, inside the

battery housing. Clean all corroded

battery contacts with a pencil

eraser or baking soda solution.
