The following manual provides important safety information and instruction. Please read this manual before oper-
ating your new trailer. It is important to follow safety instructions and cautions.
We acknowledge that not every situation or combination of tow vehicle and trailer can be addressed, therefore we
ask that you use sound judgment after reading the following outlines.
Some components may be produced by a third party. When available, separate service manuals and instructions
may apply.
Serious Hazards
Loss of control of the tow vehicle/trailer combination could result in serious injury or death. The most common
causes for loss of control include:
•Failure to adjust driving behavior when towing a trailer
•Immoderate speed – Driving too fast for the conditions
With ideal road conditions, the maximum recommended speed for safely towing a trailer is 60 mph. If you drive
too fast, the trailer is more likely to sway, increasing the possibility for loss of control. In addition, it is possible that
the tires may overheat, increasing the chance of a blow out.
Decrease your speed as road, weather, lighting, and other conditions decline.
•Improper sizing of the tow vehicle for the trailer
Trailers that weigh too much for the tow vehicle can cause unsafe stability issues which can lead to loss of control
and a serious accident. Know your vehicle tow rating and Gross Combination Weight Rating (GCWR.) Vehicle
manufacturers will provide you with maximum towing capacities, as well as the GCWR. The additional strain put
on the engine and drive-train of the vehicle may also lead to serious maintenance problems. For these reasons,
the maximum towing capacity of your towing vehicle should not be exceeded. The towing capacity of your vehicle
can be found in the tow vehicle's Owner's Manual.

Use of a hitch with a load rating less than the load rating of the trailer can result in loss of control and may lead to
a serious accident. Ensure that your hitch and tow vehicle are rated for the Gross Vehicle Weight Rating (GVWR)
and tongue weight of your trailer.
•Overloading and/or improper weight distribution
The total weight of the load you put in or on the trailer, plus the empty weight of the trailer itself, must not exceed
the trailer's Gross Vehicle Weight Rating (GVWR.) If you do not know the empty weight of the trailer plus the car-
go weight, you must weigh the loaded trailer at a commercial scale. In addition, you must distribute the load in the
trailer such that the load on any axle does not exceed the Gross Axle Weight Rating (GAWR.) The GVWR and
GAWR are located on the OEM certification and VIN label attached to the front frame of the trailer.
Never exceed the trailer Gross Vehicle Weight Rating or the Gross Axle Weight Rating. Do not load a trailer so
that the weight on any tire exceeds its rating.
Improper front/rear load distribution can lead to trailer sway and poor handling conditions. Undesirable trailer
sway results from tongue weights that are too low, while tow vehicle instability results from tongue weights that
are too high.
Uneven left/right load distribution can cause tire, wheel, axle or structural failure. To the extent possible, be sure
your trailer is evenly loaded left/right. Towing stability also depends on keeping the center of gravity as low as
possible.
Make certain the tongue weight is within the allowable range. Keep the center of gravity as low as possible.
•Unsecured loads
Your trailer may be designed for specific cargo, such as reels, or poles. If your trailer is designed for specific car-
go, do not carry any other cargo such as people, hazardous substances or containers of flammable materials.
It is important to avoid shifting cargo. The trailer ride can be bumpy and rough. Securing cargo so that it does not
shift or bounce out of the trailer is imperative. Tie down all loads with proper sized fasteners. Always secure doors
or lids if present on your trailer by securing it's latch.
•Improper braking and steering under sway conditions
When towing a trailer, you will have decreased acceleration, increased stopping distance, and increased turning
radius. The trailer will change the handling characteristics of your towing vehicle, making it more sensitive to
steering inputs and more likely to be have its stability affected in windy conditions or when passed by large vehi-
cles. You will also need to adjust driving accordingly, i.e. taking a longer distance to pass and allowing for in-
creased braking distances, etc.
Common sense measures may be necessary, such as; being alert for slippery conditions, anticipate trailer sway
and be ready to reduce speed, use small, trim-like steering adjustments to re-gain control, check rear view mirrors
frequently to evaluate trailer towing and traffic conditions, use a lower gear when driving downhill or on long
grades, be aware of your trailer height at all times, especially when approaching bridges and roofed areas.
•Improper or incorrect coupling of the trailer to the hitch
It is critical that the trailer be securely coupled to the hitch, and that the safety chains and emergency break-away
cable (electric brakes) and air hoses (air brakes) are correctly attached. Uncoupling of the trailer during transit can
lead to a serious accident or a fatality.
Ensure that the pintle hook capacity rating, including installation, is sufficient for the GVWR and the tongue weight
of the trailer being towed. Make sure that the pintle hook is physically compatible with the trailer drawbar. Compat-
ibility information is available from the pintle hook manufacturer.
This information is the property of Sauber Mfg. Co. and is intended for customer use only.

Observe the drawbar and pintle hook for wear, corrosion and cracks before coupling. Replace worn, cracked or
corroded components per the manufacturer's recommendations.
Ensure the hitch drawbar and pintle hook are installed with grade-8 fasteners and are properly torqued before
coupling to the tow vehicle.
Do not move the trailer if any of the following conditions appear:
•The drawbar is not secured and locked to the pintle hook.
•The safety chains are not secured to the tow vehicle. If your trailer detaches from the pintle hook for any
reason, we have provided safety chains so that control of the trailer can still be maintained. Improper rig-
ging of the safety chains could result in loss of control. Fasten chains to the frame of the towing vehicle.
Do not fasten chains to any part of the hitch unless the hitch has special holes or loops specifically de-
signed for that purpose. Cross chains underneath hitch and coupler with enough slack to permit turning
and to suspend the trailer tongue should it become detached.
•The trailer jacks are not fully retracted.
Do not tow the trailer on the road until:
•The trailer breakaway system is operational
The breakaway switch must be connected and verified. If equipped with electric brakes, your trailer will be
equipped with a breakaway system that can apply the brakes on your trailer if it becomes detached from the tow
vehicle for any reason. The breakaway system, including the battery, must be in good condition and properly
rigged to be effective. An inoperative breakaway can result in a runaway trailer. The breakaway cable must be at-
tached to the towing vehicle and not to any part of the hitch. Before towing the trailer, test the system. If the sys-
tem is not working, do not tow the trailer. Have it serviced or repaired.
•Tires and wheels are checked
Failure to maintain proper tire condition and pressure can lead to loss of control.
Just as with your tow vehicle tires, the trailer tires and wheels are important safety items. It is essential to inspect
them before each tow.
If a tire is found to include defects such as a bald spot, bulge, cut, cracks or is showing any cords, replace before
towing. Have the tires inspected by qualified persons. Check inflation pressure on all tires prior to towing.
Failure to keep lug nuts tightened properly may cause the wheels to be seated to the hub improperly. Before
each tow, check to make sure they are properly torqued. The proper torque for lug nuts is listed in this manual
and available from the manufacturer. Use a torque wrench to tighten the lug nuts, use a crisscross star pattern.
Lug nuts are also prone to loosen after first being assembled. When driving a new trailer (or after wheels have be
remounted,) check to make sure they are tight after the first 10, 25, and 50 miles of use and before each tow
thereafter.
•The trailer lights and brakes are connected and checked
Be sure the trailer brakes and all the lights on your trailer are functioning properly before towing your trailer.
Brakes and lights on a trailer are controlled via a connection to the tow vehicle.
Electric Brakes
Check the trailer brake lights by having someone operate the brake and turn signals on the tow vehicle
while you visually verify it is functioning. If your trailer has electric brakes, your tow vehicle will have an electric

brake controller that is required to be installed at the driver's position that sends power to the brakes. To check
the condition of the electrical brake system, pull the breakaway pin and check for the illumination of the green LED
indicator light. When fully lit, the battery is charged and the system wiring is correct. To test this system, operate
the brake controller while trying to pull the trailer at a speed of less than 5mph to verify they are operating and you
can feel them engage.
If your trailer has hydraulic, or “surge” brakes, pull the emergency breakaway lanyard to check the operation of
the emergency brake system.
•Proper Tongue Weight is established
It is critical to have a portion of the trailer load carried by the tow vehicle. The trailer tongue should always exert a
downward force on the hitch. Proper tongue weight is essential to good trailer tracking and safe operation. If too
little weight is distributed to the tongue, towing will be erratic. Too much tongue weight may overload the towing
vehicle’s rear axle or the pintle hitch rating. Ten to twenty percent weight transfer is considered a normal range.
Smaller, single axle trailers can transfer weight on the high side of this range. Larger, multiple axle trailers are de-
signed to transfer less because of the limited capacity of the towing vehicle’s rear axle.
When necessary, tongue weight can be controlled by distributing the load or by adjusting the pintle eye.
Even loading is ideal, but when this is not possible, place more weight toward the trailer front to provide a safe
tongue weight. Be aware that too much tongue weight from an uneven load can overload tow vehicle compo-
nents. It is incumbent upon the operator to provide a safe, towable tongue weight without excessive hitch weight
transfer that could place the tow vehicle in a non-compliant condition. If your trailer is equipped with an adjustable
eye, lowering it will generally increase tongue weight while raising it will decrease tongue weight - especially on
multi-axle models. Additional loading instructions may be included with your trailer, and should be followed.
Once the trailer pintle eye is secured in the towing vehicle hitch, cross the safety chains and connect them
to the rings provided at the towing vehicle bumper. Insert the electrical connection cord and check trailer lighting.
Connect the air glad hands if present and check brake operation. Ensure the trailer axle(s) do not exceed their
GAWR and the entire trailer and load does not exceed the GVWR rating.
•Grounding
Your trailer is equipped with a bronze grounding lug. When the trailer is used near energized conductors
the trailer must be grounded. A grounding lug is provided to help you follow your company’s safety prac-
tices.
•Outriggers
Stability is an important part of safe trailer use. Because the towing vehicle can provide additional stabili-
ty, leave it connected to the trailer when you can. Set the rear outriggers to their lowest level. If you need
to decouple the towing vehicle, lower the front jack slightly, set the outriggers and then raise the jack to
seat the outriggers firmly in the ground.
•Wheel Chocks
Set the chocks at each rear wheel in the direction of the expected load or grade.

•Do not modify your trailer
Your trailer is a custom engineered piece of equipment. Essential safety items can be damaged by altering your
trailer. The simplest modifications, such as driving a screw or punching a hole to install a hanger can inadvertent-
ly damage an electrical wire or other hidden component. Before making any alteration to your trailer, contact
Sauber Mfg. Co. at [phone].
Series 1602 Tensioning Brake
Apply the brake by rotating the tensioning adjustment wheel clockwise. Continue to apply braking pres-
sure until the desired wire sag is present. The brake has a maximum torque of 3000 ft-lbs. This provides 3000 lbs
of line tension 1’ from the reel bar center. If wire is filled to 2’ from the reel bar center the resulting line pull would
be 1500 lbs (3000/2).
The reel bar can be removed with a continuous sling. Loop the sling through the hooks on the power arm
and reel positioning collar and elevate the load line. Your tongue and groove assembly will automatically line up.
There is nothing to disassemble.
Model 1000-2S 2-Speed Retriever
Engage the retriever by moving the black engagement lever towards the outside of the hub. Pressurize
the retriever using the tool circuit on your line truck or power source. The bi-directional valve has full feathering
capabilities and is set to relieve at 2250 PSI. The 2-Speed Retriever can be set to high speed/low torque, or low
speed/high torque mode by engaging or disengaging the knurled plunger at the rear of the hydraulic motor. The
motor can be shifted from one mode to another “on the fly” while under load. Set the plunger “out” for operation in
high speed mode; set it “in” for high torque operation. When paying wire out under tension or “free-wheeling”, al-
ways disengage the hub. This is necessary because the directional control valve has a tandem spool to prevent
loss of line tension when in neutral. This spool will not allow oil to circulate and may cause damage to the motor
and drive mechanism if the hub is forced to rotate while in the engaged position. The spool will, however, allow oil
to circulate to tank while in neutral.

Power Source
PrefaceThank you for choosing Sauber Mfg. Co. Your new generation Power Source represents the state of the
art in mobile hydraulic power. We welcome your suggestions on its improvement and stand willing to assist you if
any questions arise during its operation. With a very small amount of maintenance, and by understanding its oper-
ation, your Hydraulic Power Source will provide you with years of good service. If we can help you in any way
please contact your national account representative toll free:
Voice Communications: [phone]
Fax Communications: [phone]
Principle of Operation
Your power source is designed as a compact, reliable source of hydraulic power. It features the best pow-
er plant technology available. The vertical shaft engine is mounted directly to the power source cover. Beneath
the cover a mounting bracket houses the hydraulic pump. The pump is driven through a flexible shaft coupling set.
It draws oil from the tank bottom through a suction strainer. Pressurized oil is delivered through a manifold provid-
ing flow and pressure regulation prior to being delivered to the tool. Oil is filtered prior to returning to the tank.
Pre-Operation Checks
Prior to using your new power source, make a complete review of the engine information provided with
this manual. After doing so, invest a few minutes prior to starting the power source to perform these simple
checks:
•Fuel Level
•Engine Oil Level
•Recoil Rope Condition
•Air Cleaner Condition
•Hydraulic Oil Level and Condition
•Signs of Excessive Hydraulic Leaks

Engine Starting & Operation
To assure easy starting be sure the pressure and return hoses are connected to our Retriever or any tool
that will allow oil to circulate to the system tank in neutral. The valve spools in these tools are commonly referred
to as “open” or “tandem” center spools. An attempt to start the power source without this connection will result in
an engine stall condition and will strain the engine and pump components. If the engine is cold, the choke will be
required. On single cable systems, pull the throttle out as far as possible to engage the choke. Depressing the
control will disengage the choke. If the choke is controlled separately, its function will be labeled. Pull the cable
out to engage the choke, push in to disengage. On electric start models, engage the starter with the keyed switch
provided or pull the recoil rope with the key switch in the “RUN” position.
When work is being done, the power source should normally be operated at full throttle. This will provide
maximum power capability. The unit should be returned to idle or shut off when power is not required. This will
help reduce system heat build-up and conserve fuel. Although the unit may be run at “mid-throttle” to conserve
fuel or reduce noise, recognize that the engine will stall prior to reaching system relief pressure. Flow is also re-
duced anytime the engine is operated at less than full throttle or when the flow control knob is rotated counter-
clockwise.
Use With Sauber Retrievers
Your power source was designed so that both Retrieving and Tensioning functions can be used without
disconnecting hydraulic lines. Therefore, once the hydraulic lines are connected, they will need to be removed
only to run other hydraulic tools. Sauber Retriever valves include an internal relief, therefore your power source
relief should be set to the maximum level while operating Sauber Retrievers. Disengage Retriever when tension-
ing.
Use With Sauber Brakes
The power source will have no effect on brake unit operation. The power source can be off or running,
connected or unconnected during brake operation.
Hydraulic Leaks
With any hydraulic system, some small amount of leakage and spillage are common; but, persistent leaks
pose a problem from a clean-up and operation standpoint. When hydraulic oil is found, check the following areas:
Quick Couplers
Tighten or replace as necessary; try dripless fittings if problem persists
Tank Lid
Remove tank lid and re-seal w/ new gasket and gasket compound
Engine Mounting
Remove tank lid and engine and re-seal w/ gasket compound
Sight Gauge
Remove sight gauge and replace O-rings or entire gauge
Tank Drain
Tighten drain plug
Return Line Filter

Oil Filtration
Keeping the oil clean in your power source is one of the best precautions you can take to ensure maxi-
mum system life. There are three components to the filtration system. The sump strainer, located inside the tank,
filters large particles introduced into the tank. The return line filter is located outside the tank. This filter has a back
pressure gauge that shows relative filter effectiveness. As the filter becomes dirty and clogged, the dial will move
into the red area of the gauge. This signals that a filter change is required. The third element of the filtration sys-
tem is the fill/breather element. This filter is designed to keep large scale impurities from entering the tank during
fill operations. Hydraulic oil works at peak performance when it is pure. Therefore change the oil and flush the
tank if water or impurities inadvertently enter the system. A drain plug is provided at the base of the tank. Always
change the return line filter with the hydraulic oil.
Oil Level/Temperature Gauge
At the power source side a sight gauge has been installed. This gauge shows the level of hydraulic fluid in
the tank, its temperature and visual condition. Look for signs of impurities or water (cloudiness) in the glass. If
found, refer to the oil filtration section above. On level ground, the optimal oil level is 1” from the top of the sight
gauge. Over-filling the tank will result in leakage through the tank/lid seal. Low oil levels will cause increased sys-
tem heat and may “starve” the pump resulting in loss of flow and pressure. Check the temperature gauge periodi-
cally during use. Hydraulic oil temperatures should not exceed 250 degrees Fahrenheit. If this temperature level is
encountered, we recommend an optional oil cooler for your system.
Pressure Gauge & Control
Your unit is equipped with a gauge that indicates operating pressure in pounds per square inch (PSI).
While in operation, the system pressure gauge will indicate pressures between 50 PSI and the maximum pump
pressure shown in the Components Sourcing Information section. The system pressure should correlate to the
amount of work being done by the tool in use. If it appears that this relationship is not true, check for restrictions in
the line or excessive heat build-up.
The maximum system pressure can be controlled by changing the relief setting at the side of the power
source. Turn the relief screw counterclockwise to lower the relief setting. Rotating it clockwise will raise the relief
setting. Always make certain the relief setting is set at least 100 PSI below the engine stall level. Many tools, in-
cluding our Retrievers have their own internal relief. The lowest relief setting in the system will prevail. Set the
power source relief at the maximum level unless you wish to limit maximum tool power or your tool does not have
internal relief.
If the power source will not produce its rated pressure, check other reliefs in the system. Also check for
blockage between the pump and the pressure manifold/gauge. In order to produce maximum pressure, the engine
must be running at top performance. Any reduction in engine horsepower will reduce system pressure and/or flow.
If engine performance is satisfactory, check the pump output.
Hour Meter
Your system is equipped with an hour meter. Use this meter to track service intervals shown in mainte-
nance section.

Flow Gauge & Control
Tool speed can be controlled by the flow control knob located above the “Slower/Faster” placard. The flow
can be read directly from the flow meter located on the instrument panel. Flow is indicated in liters per minute
(LPM) and gallons per minute (GPM). For most applications full flow is recommended. Some tools, however, re-
quire specific flow rates for optimal performance. This information should be available from the tool manufacturer’-
s documentation. Sauber Retrievers can be operated at flows up to 20 GPM and therefore can be run at full flow. If
oil flow is at or near 0 GPM rotate the flow control clockwise until desired flow is restored. If flow does not respond,
check the hydraulic oil level in the tank and ensure that the unit is not being operated on a slope exceeding 10 de-
grees. Finally, check the condition of the pump.
