SAFETY SUGGESTIONS
1.
Do not operate or service this equipment until you have
been properly trained and instructed in its use and have
read the operation and service manual.
2.
Do not operate this equipment on uneven ground.
3.
Do not drive with the hoist in the
dump position or with the hook to
the rear.
4.
Do not exceed 1,500 Engine RPM when operating the Power Take Off (P.T.O.).
Never leave the P.T.O. in gear while transporting.
5.
The hoist must be used with containers that properly fit the hook and rear hold-
downs. The container specifications must match the hoist specifications.
6.
Keep the containers and hoist in good working order. DO NOT use if repairs are
needed. Perform periodic inspections and maintenance as required by the
maintenance section of the operator’s manual.
1-4

SectionI:Introduction

1.0.INT.SL-412
7.
Make sure work area is clear of people and obstacles prior
to dumping or unloading containers. SwapLoader strongly
recommends that a backup alarm be installed on the truck
chassis. The operation of the hook hoist is that the truck is
backed up to the body to pick it up and so there is a
potential pinch point between the body and the hook.
8.
Any container, which is on the hoist, MUST be unloaded
prior to performing any repairs or maintenance to the hoist.
Also, DO NOT allow any person to work on or be under the
hoist in a raised position without first installing adequate
safety blocks to eliminate all possibility of the hoist
accidentally lowering. SwapLoader strongly recommends
that, if possible, the container should be dismounted from
the hoist prior to performing any maintenance to the hoist.
9.
It is the responsibility of the owner and/or installer to ensure that any additional safety
devices required by state or local codes are installed on the SwapLoader Hoist
and/or Truck Chassis.
10.
Keep away from overhead power lines. Serious injury or
death can result from contact with electrical lines. Use care
when operating hoist near electrical lines to avoid contact.
11.
Avoid contact with high-pressure fluids. Escaping fluid
under pressure can penetrate the skin causing serious
injury. Avoid hazardous conditions by relieving pressure
before disconnecting hydraulic or other lines. Tighten all
connections before applying pressure. Search for leaks with
a piece of cardboard, while protecting hands and body from
the high-pressure fluids.
12.
It is the responsibility of the owner to provide proper maintenance of the Safety
Decals. Regular inspection and replacing of Safety Decals that have any fading or
damage which would impair their function should be done (See the illustration on the
following page for location of Safety Decals).

INITIAL INSPECTION
When the hoist is installed and ready for delivery, it is
your responsibility to fill out and submit the Product
Registration Form. Visit
https://www.swaploader.com/warranty-registration/ to
complete this form.
When the SwapLoader hoist is received from the factory,
you should inspect the hoist for damage, which may have
occurred in shipment. If damage has occurred, you
should contact the shipper immediately. Be sure to note
any damage or missing items on bill of Lading.
When you receive your SwapLoader hoist, it is your
responsibility to make sure you have received all the parts
and pieces that were ordered, within 30 days of the
invoice date of the hoist. Lay out all the options, loose
parts and accessories on a table and compare the items
received vs the Packing List and the Loose Parts Box
List(s) shipped with the hoist order.
If you have any problems, shortages, or questions, please
contact SwapLoader U.S.A., Ltd. immediately.
GENERAL INSTALLATION PROCEDURE
The installation of the SwapLoader on a truck chassis will generally follow these steps:
1. Install hoist assembly onto truck chassis.
2. Mount the hydraulic control valve to the hoist and install the hydraulic plumbing from the
control valve to the hydraulic cylinders. Then install the control levers in the cab and
route the control cables to the hydraulic control value assembly.
3. Install the hydraulic tank, hydraulic filter, and hydraulic plumbing between the hydraulic
tank and the control valve assembly.
4. Select and install the P.T.O. on the truck transmission. (Note: This can be done prior to
hoist installation on the truck chassis.)
5. Install the hydraulic pump and the plumbing from the pump to the hydraulic tank and
control valve assembly.
6. Fill the hydraulic tank with oil, bleed the air from the pump suction line, and start up the
unit.
Although SwapLoader attempts to include the mounts and attaching fasteners with each hoist
unit, your installation may require some additional mounts or modifications. If you have
problems with your installation, please contact SwapLoader at 1-888-767-8000, as we may be
aware of another customer who has installed a SwapLoader on a similar truck chassis.

HOIST INSTALLATION TO TRUCK CHASSIS
1. Place the SL-412 hoist assembly on the truck chassis. The truck chassis mounting surface
should be flat without any steps or protrusions. If necessary, shim bars need to be added to
ensure a flat surface on which to support hoist. It is advised to clamp the main frame of the
hoist to the truck chassis prior to install of the mount brackets.
The clear frame dimension indicated in Fig. A allows for the overall length of the hoist plus 5
inches for cab clearance and rear light bar mounting. Extra frame length may be needed to
allow for mounting additional accessories (e.g., Cab Guard, Tarper, Light Kit, Stabilizer,
etc.). For example, when mounting a light kit on a truck with a long CA, check that the hoist
and the light kit are positioned far enough back to eliminate any interference between the
fender and the light kit. You should also consider the final weight distribution regarding the
bridge code when positioning the hoist.
NOTE:
THE ABOVE SPECIFICATIONS ARE A MINIMUM REQUIREMENT. IT IS THE RESPONSIBILITY OF THE OWNER/
OPERATOR TO ENSURE THE COMPLETED CHASSIS MEETS OR EXCEEDS ALL FEDERAL, STATE, AND LOCAL
REGULATIONS. ALSO, THE HOIST SHOULD NOT BE USED TO LIFT AND HAUL ANY LOAD THAT EXCEEDS THE LOAD
RATING OF ANY OF THE INDIVIDUAL COMPONENTS OF THE COMPLETED CHASSIS (TIRES, AXLES, SUSPENSION,
ETC.)
FigureA

SectionII:Installation
2.0.INS.SL-412
2. There are two types of mount brackets used on the Model SL-412 hoist as indicated in Fig.
Band Pg. 5-7. They are the angle brackets (Pt. No 89H51) and the mid brackets (Pt. No.
89H46). Locate the mount brackets on the side of the hoist as indicated in Fig. B. These
dimensions are flexible because of possible interference with chassis components. Also
allow for mounting the control valve assembly and the hydraulic tank. You should consult
the truck chassis supplier for any limitations regarding drilling mount holes in the truck
chassis frame rails. Typically, the holes must be at least 2 3/4” from the top of the truck
chassis rails (reference Fig. C, D & E). Once the locations of the mount brackets have been
determined, use the mount
brackets as a template for marking
the mounting holes in the truck
chassis frame rails. Drill the 21/32”
diameter holes required and attach
the brackets to the truck chassis
with the 5/8” diameter bolts,
washers, and locking hex nuts
provided. Torque to 110 ft.lb.
3. Bolt the mount brackets to the hoist
main frame as indicated on Fig. C,
D and E. You may need to modify
the mount brackets or add shim
plates to allow for variances in the
width of the truck chassis as well
as to allow for top rivets, stepped
channels, etc.

41H01) to the main frame as indicated on
Pg. 5-11 with the fasteners provided (see
Pg. 5-7).
2. Mount the hydraulic control valve assembly
(Pt. No. 20P88) to the valve mount bracket
as shown on Pg. 5-11 with the fasteners
provided.
3. Install the hydraulic adapters, connect the
hydraulic tubing & hoses (Pt. Nos. 13P11,
11P98 & 11P99) to the control valve
assembly as indicated on Pg. 5-9. The
tubing should be supported by the clamp
assemblies that are provided in the Loose
Parts Box (see Pg. 5-7).
4. Determine the best location in the cab for
the control levers (Pt. No. 20P08). The
location should be such that the controls
can be easily reached while operating the
truck. A control lever console (Pt. No.
20P09) is provided to facilitate the mounting
of the control levers (see Pg. 5-11).
5. Assemble and install the control lever
console (see Fig. F). Typically, the console
is fastened to the floor of the cab and the
control cables are routed through additional
holes drilled in the floor. Your installation
may require that additional brackets be
fabricated, or other modifications made.
6. Attach the control cables to the control
levers and route the cable through the holes
in the cab. Install the control levers in the
console. Levers should be installed such
that when the levers are pushed forward the
control cable is extended. See Pg. 5-11
(Manual Control Assembly) for control lever orientation.
7. Route the cables to the control valve location and attach them to the control valve with the
bonnet connection kits provided (Pt. No. 20P10). See the following instruction sheet for
installation procedures. The control cables supplied are 96 inches long. Your mounting
may require different length control cables, which can be purchased locally or through
SwapLoader. Take proper care when routing the control cables, as a good cable path is
essential for a proper operating system. Keep bends in the cable path to a minimum and be
as generous as possible. Under no circumstances should any bend be tighter than an 8"
radius. Protect the cable from heat above 225 degrees F. and avoid hot areas such as
exhaust pipes, etc. Protect the cable from physical damages such as pinching or crushing,
