ENGLISH

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, sufficiently

spacious and not in the vicinity of 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 is thrown
about.

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 (torque wrench or battery
hydrometer).

(3) Set the parking brake and place blocks in front of

wheels (when they're contacting the ground) to
prevent machine 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
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) Once the equipment is fully assembled, select a

safe place for a test run. Prevent onlookers from
approaching the equipment.

To avoid serious injury or death:
A Do not start engine or operate levers from

anywhere other than the seat.

To avoid serious injury or death:
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 WOODEN CRATE

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 machine when cut.

2. Saw the crate as indicated in the figure below.

A Sawing outside the indicated area may damage the

machine or accessory parts.

A Be sure that the crate is free of other obstructions (e.g.

nails, staples and etc.).

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.

BUNPACKING IRON CRATE

1. Hook nylon ropes at the four corners of the iron-crate's
top stay. Pull up the nylon ropes until they get just tight.

2. Remove the six bolts from behind the vertical supports
on both sides of the iron crate.

3. Lift and detach the top frame of the iron crate.

A In lifting the top frame, be careful to keep the crate's

vertical supports from scratching the machine.
