As the owner and / or operator it is ultimately your responsibility to insure personal
safety and to operate this machine in a safe manner. Your good judgment and the following
precautions will help you to avoid costly accidents and minimize personal risk.
• DO NOT move or operate this machine until you have read and understand the instruc-
tions in this manual.
• NEVER allow untrained persons to operate this machine.
• DO NOT attempt to service this machine while it is in operation.
• MAKE CERTAIN all mechanical and hydraulic tension has been released before attempt-
ing to service the machine.
• CHECK all nuts and bolts regularly for tightness.
• PERFORM REQUIRED MAINTENANCE as prescribed or as necessary to keep this ma-
chine in safe operating condition.
• KEEP ALL SPECTATORS at a safe distance.
• STAY CLEAR of high pressure supply lines, especially when first pressurizing the system.
• DO NOT remove or alter any of the shielding from this machine.
• BE CERTAIN that the machine is securely anchored (using the stabilizer legs) before un-
spooling the hose.
• KEEP WELL CLEAR of all moving parts.
• NEVER tow this machine at speeds greater than 10 MPH / 15 KPH and be certain the tow
vehicle has adequate braking capacity to maintain safe control at all times.
GENERAL PRECAUTIONS
“SAFETY IS JUST A WORD UNTIL PUT INTO PRACTICE”
This symbol, the safety-alert symbol, indicates a hazard and conforms to ANSI
/ ASAE S350. When you come across the safety-alert symbol in this manual,
make certain you fully understand and abide by the given instructions.
Keep the chassis of the machine on firm and level ground. A Cadman Traveller
has a high center of gravity. It is essential that it be operated from a stable posi-
tion to prevent roll over.

3
SAFETY DECALS
The safety decals on this machine are intended to warn the operator of potentially haz-
ardous areas. These decals must be properly maintained. This includes;
• keeping all safety decals legible
• replacing any decal that becomes illegible
• replacing any decal that is missing
• if applicable, include the current safety decal specified by Cadman Power Equipment Ltd.
on any component installed during repair
Contact Cadman Power Equipment Limited to obtain replacement safety decals.
When replacing safety decals reinstall them onto there proper locations.
SAFETY SHIELDS
The shielding installed on your Cadman Traveller is designed to help guard against
accidental entanglement in the moving parts of the machine. These shields must be removed
ONLY for the purpose of repair or periodic maintenance as described in the “Required Main-
tenance” section of this manual. The shielding MUST be immediately re-installed BEFORE
putting the machine back in service.
STABILIZER LEGS
All Cadman Travellers are equipped with two (2) stabilizer legs. The stabilizer legs
MUST be lowered each time the machine is used, no matter how little hose is pulled out!
Regular inspection of your pipe couplings, tubing and gaskets should be part of
your regular set-up routine. Any defective parts should be replaced or taken out
of service.
Pressurizing your Cadman Traveller must be done slowly and cautiously to
purge all the air from the system before bringing the system up to full operating
pressure. (see “Field Set Up And Operation” #16 on pg. 13 for further explana-
tion)
WARNING
Operation of a Cadman Traveller without the shielding in place could re-
sult in serious personal injury or death!
WARNING
Failure to properly use the stabilizer legs may result in unwanted frame
movement or machine upset with the potential to cause serious injury or

APPLICATORS AND ACCESSORIES
There are a variety of applicators available to be used with your Cadman Traveller.
Ask a Cadman Power Equipment Limited representative about your options.
Cadman Power Pak Cadman Manure Boom Cadman Broadcast Cart
Many accessories are also available for use with a Cadman Traveller (i.e. Cadman
Power Pak) Refer to there respective manuals before using any piece of equipment with your
Cadman Traveller.
GUN CART
The gun cart assembly of the Cadman Traveller has adjustable rear track widths as well
as provisions for adding additional weight to the gun cart frame. The gun cart should be ad-
justed to the widest track width that row spacing will allow. This will provide greater stability for
the gun cart.
With gun flows exceeding 240 gallons per minute, or when operating on uneven terrain,
additional weight MUST be added to maintain gun cart stability and help prevent cart upset.
Additional weight may be gained by “loading” the
rear gun cart tires and/or using tractor front end
weights as required.
CAUTION
If the gun is set so that it rotates forward of the
rear wheels of the cart (toward the reel), stop the
retrieve cycle NO LESS than 10 FEET out from
the machine in order to prevent gun damage
caused by the gun hitting the cart lift assembly.

REQUIRED MAINTENANCE
Prevention of mechanical failure is the goal of any good maintenance schedule. Severe
service uses such as liquid manure application, municipal and industrial uses, custom slurry ap-
plications, etc. require timely, trouble free operation of your equipment. The secret to preventing
unwanted down time is to adhere to a maintenance schedule suited to the way you use the
equipment. Your maintenance schedule should include the following minimum requirements;
EACH USE
1 Check to be sure BOTH shut off switches and the safety shut off switch are working. Repair
or replace a defective switch BEFORE operating the machine. (see top of pg.14)
2 Check to be sure the compensator safety switch is properly adjusted and working. The en-
gine must shut down before the shut off bar contacts the frame. (see top of pg. 14)
DAILY
1 Check the engine oil level and air filter condition.
2 Check to be sure that the indexer drive button
and connecting link are in good condition. Insure
that the slide rails are well greased. (see illustra-
tion)
3 Check the alignment and tension of the main
drive chain. Adjust as necessary.
AFTER THE FIRST 25 HOURS
1 Change the oil in the Honda engine. Refer to the
Honda engine manual for detailed maintenance
instructions.
2 Change the oil in the transmission gearbox. See
“LUBRICANTS” section for oil type and fill level.
EVERY 50 HOURS OF USE
• Check ALL wheel bolts (using a lug wrench) to insure tightness.
EVERY 100 HOURS OF USE
1 Change the engine oil. Consult the Honda engine manual for further information on oil re-
quirements and change intervals as well as other required engine maintenance.
2 Lubricate the following;
3 Lubricate all chains.
4 Check the oil level in the transmission gearbox. Replenish as necessary.
5 Check for oil level in the indexer gearbox.
• Turntable bearing ring
• Indexer slide rails
• Indexer idler block
• Main drive chain idler arm pivot
• Drive pulley lead screw

6 Check the tire pressure and maintain from 36-40 PSI.
EVERY 250 HOURS OF USE
Disassemble, clean, inspect and re-pack the gun cart wheel bearings. Replace any defective
components as required.
BEFORE STORING
1 Drain the hose. This is easily done by pulling out all but one (1) coil of hose along a level
path. Remove the drain plug from the gun cart. Use the Honda engine or a tractor PTO shaft
to wind in the hose.
2 Disassemble and clean the variable speed pulley mounted on the engine. Remove the
“moving face” of the pulley. Clean the bronze bushing and shaft of gum and belt dust and lu-
bricate with a thin coat of light oil.
3 Disassemble, clean, inspect and re-pack the main chassis wheel bearings.
4 Lubricate all chains.
5 Prepare the Honda engine for storage. See the storage instructions provided in the Honda
engine manual.
BEFORE START UP (After long term storage)
1 Review this manual to refresh your memory regarding the proper operation of this machine.
2 Fill the fuel system with fresh fuel.
3 Change the oil in both the transmission gearbox and the indexer gearbox.
4 Check and adjust the tire pressure to 36 - 40 PSI.
LUBRICANTS
Grease: Any good grade of multi-purpose, waterproof
grease is acceptable.
Engine Oil: Consult the Honda owners’ manual for
oil recommendations.
Transmission Gearbox: SAE 80W or 90W gear oil.

CAUTION
DO NOT leave the machine unattended during the hose draining process. Without fluid
pressure present, the hose may flatten slightly causing it to lay improperly on the drum. It
may be necessary to manually adjust the hose position on the hose drum during the drain-
ing process.

FIELD PREPARATION AND OPERATING TIPS
1 If your field width is greater than can be irrigated in one (1) pull but narrower than two (2)
pulls, divide the field into two (2) equal width pulls instead of one (1) full width pull and one
half width pull. (see illustration below)
There are two (2) reasons for this.
• Even division of the field allows
maximum versatility to combat
rising winds from any direction.
• The gun cart will track straight
and be less affected by gun
thrust.
During quarter circle operation (from the edge of a field), gun thrust tends to steer the
gun cart in the direction in which water is being thrown. This occurs when the gun is nearly per-
pendicular to the hose lane. If conditions dictate that a quarter circle pass is unavoidable, pre-
pare the travel lane by preparing a shallow trench for the hose and the cart wheels to follow.
Adding extra weight to the rear of the gun cart is also beneficial. If these preparations are not
possible or prove inadequate, reduce the size of the gun nozzle to reduce the amount of thrust.
Remember to adjust the retrieve rate to maintain your desired application rate.
During normal full pattern operation, (the gun operates to both sides of the cart) gun
thrust will correct this steering action automatically. The side to side movement of the cart
should be no more than the width of the cart’s rear wheels.
2 If you typically hill your row crops and plan to leave open travel lanes, hill and cultivate your
travel lanes as well. The absence of grass and weeds will dramatically reduce the amount of
towing effort and traction required to pull out the hose. The hills will also help guide the hose
and cart through the field.
3 Crops such as sod, alfalfa, potatoes and peas provide a great deal of resistance to pulling
the hose. If you irrigate such a crop, consider uncoupling the feeder hose at the mainline
valve and pulling out the hose slightly slower. This expels a good deal of the water from the
P.E. hose, reducing the amount of towing effort required.
4 I f
a curved pull is necessary, pull a minimum of 200 feet of hose straight out from the ma-
chine chassis before beginning a long gradual curve.
5 Provide for ample head land (lane way) space to allow the machine chassis to be pivoted
and setup.
6 Where field conditions permit, always attempt to pull the hose either up or down sloping ter-
rain instead of operating on a side hill. If a side hill condition is unavoidable, provide a hilled
trench as a guide for the hose and add extra weight to the gun cart to prevent upset.
PREFERRED
CAUTION
Several hundred gallons of water can be expelled. Exercise good judgement to
prevent excessive muddying of the area near the chassis of the machine.

WHEN APPLYING LIQUID MANURE . . .
Environmental concerns seem to be driving legislative agendas in many
agricultural areas across the continent. Current and pending laws in many agricultural
regions of North America are changing the ways in which the agricultural community is
expected to manage their liquid animal waste products.
The changes in legislation typically target two main issues; run-off prevention
during and after application and soil nutrient loading.
Run off seems to be the largest concern with nutrient application. Run off may
result from several different factors, most of which are controllable. These factors
include; exceeding the soil intake rate; nutrient application on steep grades; high
application amounts; leaking mainline fittings and seals; sudden rainfall during or
immediately after application; ground frost; etc. Constant watch must be kept and
immediate action taken when necessary to prevent run off from occurring.
Soil nutrient loading depends on many variables. Some of these variables (but
certainly not all) are soil type, type of crop being grown in the irrigated area, application
timing, nutrient value of the material being applied (nutrient value should be assessed at
the time of application as it can change throughout the year), etc.
Soil type will determine the intake rate at which liquid may be applied. Cultivation
of the field just prior to application can improve the intake rate of some soils.
Great potential benefit lies in using the nutritional value of the product being
applied to replace some or all of the traditional chemical fertilizer used. Application
timing and amount are important considerations. Soil analysis taken prior to planting and
during the growth periods of the crop will help determine if there is room for further
application amounts to be added prior to crop maturity. A total management plan should
include provisions to end the crop season without surplus nutrients left as residual.
These excess nutrients typically end up in the ground water supply. Local colleges,
universities and agricultural extension services are usually a good source of information.
They can usually help you determine an application program that prevents soil nutrient
overload due to excess application.
Cadman Power Equipment Limited cannot possibly provide up-to-date
recommendations with regard to the legal obligations you must deal with in your
particular area. However, as a manufacturer of equipment used in nutrient application
(liquid manure, milk house run-off, etc.), we feel it necessary to make you aware that the
municipal, regional and state governing bodies in your area may have recently enacted
new legislation or revised existing legislation with regard to nutrient handling practices
and procedures.
It is your responsibility to make yourself aware of and abide by the current
legislation in your area. Please take the time to contact your local agricultural
representative to obtain the latest information regarding legal nutrient application and
handling.

FIELD SET UP AND OPERATION
BEFORE operating your new CADMAN TRAVELLER, inspect the machine for any
damage or parts which may have come loose during shipping. REPORT ANY DAMAGE TO
YOUR DEALER IMMEDIATELY !
1. Tow the machine to the field. Park the traveller on the head land (lane way) at right angles
to the rows to be irrigated.
NOTE : For the first use of a new machine or a machine which has been drained prior to stor-
age, start in an area which will allow you to pull out the full length of hose ( EXCEPT
for one full coil ). This will allow you to be sure that the hose is properly laid on the
base layer and properly indexed.
If you are unable to pull out all of the hose in the area you are working, pull out enough
hose to reach the base layer. This will allow you to see if the coils of hose in the base layer are
stacked tightly together. If the hose is found to be improperly indexed (the hose tries to climb
up on itself or gaps exist between the coils of hose), do the following:
• Set the hose drum so that the hose connection is at the six o’clock position (closest
to the ground).
• Fully apply the brake to prevent further rotation of the hose drum.
• Manually move the coils of hose so that they are tightly stacked together all across
the base layer of hose.
Check the position of the hose guide in relation to the hose. If the hose does not travel
straight through the hose guide and lay snugly against the drum elbow, do the following (see
following page):
• Remove the indexer shield.
• Remove the # 50 chain which runs from the hose drum axle to the indexer gearbox.
• Manually adjust the hose guide position so that the hose travels in a straight line
through the hose guide and lays snuggly against the drum elbow.
• Re-install the # 50 chain from the hose drum axle to the indexer gearbox.
• Re-install the indexer shield.
CAUTION
Before moving a traveller at any time, be sure that the drive system is fully engaged,
the engine fuel valve is in the OFF position and the transport brake is fully applied.
CAUTION
Low pressure operation can cause indexing problems. The hose indexing sys-
tem of your Cadman traveller is set up to properly index the polyethylene hose onto the
hose drum under most operating conditions. However, when operating at very low in-
let pressures (110 PSI or less), the PE hose can flatten slightly causing the indexing
system to appear to be either out of adjustment or not functioning properly. This is
probably not the case in this circumstance.
It is advisable to increase the inlet pressure at the machine to at least 110 PSI to
help prevent further hose indexing problems related to low inlet pressures.

2 Adjust the tongue jack for a level frame position during operation.
3 Release the turntable lock and rotate the upper frame to the desired operating position and
re-engage the turntable lock.
5 Shift the transmission lever to the disen-
gage position (arrow).
4 Connect both hydraulic lines from the traveller to
the tractor. Using the tractors hydraulic controls
fully extend both stabilizer jacks

CAUTION
The upper frame position MUST allow
the hose to be pulled out straight from
the machine. Adjust the upperframe po-
sition if necessary to insure proper un-
reeling of the hose.
CAUTION
Never operate the machine with only one (1) stabilizer leg extended
WARNING
If a rear pull is needed, provisions MUST be made to leave the tractor attached to the
tongue of hte machine. The tractor must be left in gear and the parking brake ingaged.
This provides extra anchoring in addition to the stabilizer legs during the retrieve cycle.

6 Adjust the brake handle position so that a slight amount of brake tension is applied. This
tension should be enough to control the hose drum and prevent loosening of the hose on
the drum when the tractor stops pulling the hose.
7 Set the track width of the gun cart as wide as possible. Lower the cart to the ground by
operating the hand winch on the side of the machine. Disconnect the lift chain from the
cart.
8 Move the tractor from the front of the machine, position it behind the gun cart and attach
the gun cart tow chain to the tractor drawbar.
9 Pull the desired amount of hose. (see illustration on pg. 11)
10 At this time, set the part circle stops on the gun.
The gun should be set behind the cart so that the
travel path remains dry until the cart passes.
(see illustration)
11 Check the nozzle size and check that the nozzle cone is secure.
12 Remove the tractor from the gun cart and clear the area of operation.
13 Connect the feeder hose to the inlet on the traveller and lock it in place. Attach the other
end to the mainline or mainline valve.
14 If the hose is loose on the drum, use the hand crank to rotate the drum to tighten the hose.

3750S / 3750 XL 1.18” or 1.24”
4000S / 4000SA 1.26” or 1.34”
NOTE: Several nozzle sizes are supplied with the sprinkler gun. The “best” nozzle choice for
your application may take some experimentation to determine. Typically, two nozzle
sizes will perform well for each model. See the chart below for nozzles to try.
CAUTION
DO NOT exceed 3 MPH while pulling out the hose
DO NOT stop suddenly at the end of your travel lane. Slow gradually when nearing the
end of the pull.
ALWAYS leave at least a 3/4 wrap of hose on the drum.

13
Insure that the hose coils are stacked tightly together.
15 Adjust the brake handle to the full “ON” position after insuring that the hose is tight.
16 GRADUAL
pressurization of the system may now begin. Keep the pressure low (under 50
PSI) until ALL the air is purged from the system and a steady stream is flowing from the
gun nozzle. AFTER all the air is purged from the system, pressure may be slowly raised to
a maximum of 150 PSI at the inlet of the machine.
NOTE: Ideally, operating pressures at the inlet will be between 120 PSI and 150 PSI. This
will allow gun pressures ranging from approximately 50 PSI to 110 PSI (depending on
nozzle size, hose size and length). Assuming proper nozzle selection has been made
based on the pressure and flow volume available, proper droplet sizing and proper
gun action, an even and uniform watering pattern will result.
17 Check the mainline and inlet elbow connections.
START UP OF THE RETRIEVE CYCLE
1 Check the engine oil and fuel levels.
2 Open the fuel valve on the engine, move the ON / OFF switch to the “ON” position and
start the engine.
NOTE: If after several attempts, the engine fails to start, check the shut off bar at the
opposite end of the machine to insure that BOTH shut off switches are depressed.
The engine WILL NOT START if either switch is released.
3 After the engine is running smoothly, check to insure that all three (3) engine shut off and
safety switches are functioning properly.
WARNING
Never leave the hand crank on the driveshaft. REMOVE IT IMMEDIATELY after use.
CAUTION
Operation of the machine with the inlet pressure below 110 PSI will allow the hose to flat-
ten slightly as it is rewound during the retrieve cycle. This flattening may cause the
hose to lay improperly on the hose drum or make it impossible for all the hose to be re-
wound. In either case, the hose must be pulled out to correct the problem. If you are un-
able to provide a minimum of 110 PSI to the inlet of the machine contact your dealer for
help in improving your system design.

14
Check the adjustment of the compensator system
when the machine is first put into service and periodi-
cally during normal use to insure accuracy. The following outlines the set-up routine and
operation of the compensator system.
• When the engine is first started after pulling out the hose,
the pulley cam should rotate, positioning it for the start of
the retrieve cycle. The cam rollers should now be near the
top of the ramp (see illustration)

SWITCH
• To check the shut off switches, lift the shut off
bar to a vertical position, while manually holding
one (1) of the two (2) switches in the depressed
position. The engine should shut off as the op-
posite switch releases. Re-start the engine and
repeat the test for the opposite switch.
• Pull the compensator frame away from
the hose drum. As the frame clears the
outer edge of the drum, the engine
should shut off.
