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, may 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:

A Do not start engine or

operate levers from

anywhere other than the

seat.

To avoid personal injury:

A Do 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 Iron Crate

1. Cut off the vinyl ropes that secure the top of the ROPS

to the iron crate.

2. Take the 4 pieces of bolts (M10 x 1.25) out of both side

of the iron crate.

3. Tie up the iron crate with a nylon band and lift up with

a hoist or fork lift. (Be careful not to damage the

tractor.)

A Fender (LH and RH) mounting bolts (1) will be used

again. Handle them with care.

(2) Set the throttle lever to the engine max. speed.

(3) Place the hydraulic control lever in the "DOWN"

(A) position to lower the three-point hitch.

2. Check points

(1) Place the lever in the "UP" (D) position and make

sure that the three-point hitch rises quickly.

(Shorter than 1 second for the full stroke.)

(2) Place the lever in the "DOWN" (A) position to

lower the three-point hitch.

(3) Place the lever in the "SLOW UP" (C) position and

make sure that the three-point hitch rises slowly.

(5 to 30 second for the full stroke.)

(4) Place the lever in the "SLOW DOWN" (B) position

and make sure that the three-point hitch lowers

slowly when attaching the rear implement later.

3. If any of the above check points are not satisfactory,

loosen the bolt (3) and reposition the lever guide (1) or

(2). Finally tighten the bolt (3).

If the lever does not return to the "NEUTRAL" (N)

position from the "UP" (D) position automatically,

loosen the bolt (4) and reposition the lever as shown in

the figure (4CBKAAEAP009A).
