ASSEMBLY INSTRUCTIONS
TO THE DEALER
1. This manual contains procedures intended to assist
the dealer in unpacking and assembling the product
before delivering to the customer.
The customer's purchase is based on confidence in
both the product and your store. Observe the
procedures in this manual to assemble and adjust
equipment for your customer's safety and satisfaction.
When fully assembled, check function of each part and
feature.
2. The following safety alert symbol marks and
indications are found throughout this manual in steps
where particular attention is required so as to ensure
your safety and to avoid product damage. Observe
the instructions in these warnings where indicated.
SAFETY
To prevent accidents, read through the following items
before starting work, and always regard safety when
working. It is your responsibility to ensure your safety on
the job.
1. Preparations
(1) Select a work site which is level, has sufficient
space, and is not close to dangerous objects.
(2) Avoid poorly ventilated
rooms.
Asphyxiation from exhaust
fumes is always a possibility
that accompanies running an
engine.
(3) Working clothes which may
be pinched or caught in the
equipment must not be worn.
Loose clothing can cause
serious injury or death.
(4) Always wear a mask and
protective goggles during
work when dust or flying
debris may be thrown by
equipment.
2. Assembly and adjustments
(1) Before assembling
equipment, read the
assembly instructions for the
product to become familiar
with the equipment and
procedures.
(2) Use only adequate and
required equipment, tools
and instruments (e.g. torque
wrench, battery hydrometer
and etc.).
(3) Set the parking brake and
block wheels to prevent
machine (or tractor)
movement.
(4) Lower the attachment or
implement to the ground
before assembling or
adjusting equipment.
(5) Before working under
suspended or raised
equipment, support the
equipment or attachment
and utilize the valve lock to
prevent the machine from
falling or moving out of place.
(6) Keep fire from cigarettes,
matches or other ignition
sources away from fuel, oil,
antifreeze and other
flammable materials.
Indicates an imminently
hazardous situation which, if not
avoided, will result in death or
serious injury.
Indicates a potentially
hazardous situation which, if not
avoided, could result in death or
serious injury.
Indicates a potentially
hazardous situation which, if not
avoided, could result in minor or
moderate injury.
Indicates that equipment or
property damage could result if
instructions are not followed.
Gives helpful information
ASSEMBLY INSTRUCTIONS2
3. After assembly check
(1) Before operating or test driving the equipment,
read and understand the operator's manual.
(2) Once the equipment is fully
assembled, select a safe
place for a test run. Prevent
onlookers from approaching
the equipment.
To avoid personal injury or
death:
ADo not start engine or
operate levers from
anywhere other than the
seat.
To avoid personal injury:
ADo not bypass-start the
equipment. Short circuiting
the starter terminal runs the
risk that the equipment will
start operating or moving
unexpectedly.
UNPACKING AND CHECKING PARTS
BUnpacking Wooden Crate
1. Cutting metal bands (if two are banded together).
Metal bands hold the two crates together as one. Cut
these bands and separate the crates.
2. Unpacking the crates
(1) Hook a hoist to the 4 corners of the crate and raise
the hoist cable until taut.
This serves to prevent the upper part of the crate
from striking the loader when cut.
(2) Saw the crate as indicated in figure 1.
ASawing outside the indicated area may damage the
loader or accessory parts.
ABe sure that the crate is free of other obstructions (e.g.
nails, staples and etc.).
(3) Raise the upper part of the crate and remove from
the immediate area.
(4) Remove the remaining slats from the crate. These
are indicated by the oblique lines in
Figure 1...

BChecking Parts
Remove all loader components. Referring to the illustration, ensure that all components have been included.
AFor LA534, the bucket is shipped separately.

ASSEMBLY INSTRUCTIONS4
TRACTOR PREPARATION
Locate the tractor on a firm level surface. Stop the engine.
BEFORE ASSEMBLY
ABefore assembling the hardware (bolts, adapters,
hoses, etc.), ensure all contaminates (grease, grit,
dust, etc.) are removed from the threads and all mating
surfaces (Tractor, Main Frames, etc.). If oil or
contamination has adhered, clean off thoroughly
before assembling (by using contact cleaner,
scrapers, etc.). If oil or contamination remains on the
threads, it may lead to damaged threads and the
loosing of hardware and/or parts.
AFor the tightening torque, see the tables at the end of
this manual. If the torque values are specified in the
text, follow that specification.
ADo not tighten any bolts firmly until most components
are attached to the tractor.
ABefore tightening all mounting hardware, start the
engine and apply down pressure with the bucket until
the loader takes the tractor weight off the front wheels
without lifting the front wheels off of the ground. Make
sure that the mounting pins can be rotated easily (Pin
on mount), or the Swift-Tach hooks can be unlocked
easily (Swift-Tach mount). Torque all bolts and nuts in
this position.
ADuring assembly of all hydraulic parts make sure parts
remain clean of contamination. If contamination
occurs it could affect the performance of the hydraulic
system.
AWhen using the tapered adapters, wrap the seal tape
around the thread part 2 or 3 times. At this time,
ensure all contaminates are removed from the
threads.
ATo avoid damage to hoses, adjust all connections to
route hoses away from sharp edges and do not twist
hoses.
AThe part number of the hose is marked on the hose
fitting, or located on the hose.
AWhen fixing the pin with the bolt and nut, do not tighten
the nut completely as shown. The clearance between
the boss and the nut should be 2 to 3 mm (0.08 to 0.12
in.).
AWhen applying label:
(1) Clean off all contaminates (dust, oil, grease, etc.)
from surface before applying label.
(2) Do not use the cotton work gloves or touch the
label adhesive surface with your hand.
AAssemble on a hard surface, preferably concrete.
ASSEMBLING LOADER KIT
BMain Frames
ABefore attaching the main frames, ensure all
contaminates (grease, grit, dust, etc.) are removed
from the threads and all mating surfaces. If oil or
contamination has adhered, clean off thoroughly
before assembling (by using contact cleaner,
scrapers, etc.). If oil or contamination remains on the
threads, it may lead to damaged threads and the
loosing of hardware and/or parts.
