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:
ADo not start engine or operate levers from
anywhere other than the seat.
To avoid serious injury or death:
ADo not bypass-start the equipment. Short
circuiting the starter terminal runs the risk that
the equipment will start operating or moving
unexpectedly.

2. Saw the crate as indicated in the figure on the right.
ASawing outside the indicated area may damage the
machine 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 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.
