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 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.
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

2
(5) Before working under suspended or raised
equipment, support the equipment or attachment
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.
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 bystanders 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.
Bprocesses
1. processes mean any process that requires priority
control due to its characteristics of having a high
probability of leading to physical injuries or fire
disasters because of abnormal values and defects in
manufacturing quality.
2. The marks in the text indicate the processes that
include the following safety characteristics.
(1) Any assembly process with important safety
characteristic values that require control to ensure
product safety.
(2) Any assembly process with characteristic values
having impact on the strength and performance of
parts.
(3) Previous occurrence of accidents related to
process (including probability.)
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 backhoe when cut.
(2) Saw the crate as indicated in the figure below.
(3) Raise the upper part of 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....... ///////
Figure 1 : Cutting area of the crate
ASawing outside the indicated area may damage the
backhoe or accessory parts.
ABe sure that the crate is free of other obstructions
(e.g. nails, staples and etc.).
