 3. CONVERSION TABLE
Method of using the Conversion Table
The Conversion Table in this section is provided to enable simple conversion of figures. For details of
the method of using the Conversion Table, see the example given below.

Example
1. Method of using the Conversion Table to convert from millimeters to inches
Convert 55mm into inches.
(1) Locate the number 50in the vertical column at the left side, take this as ⓐ, then draw a
horizontal line from ⓐ.
(2) Locate the number 5in the row across the top, take this as ⓑ, then draw a perpendicular line
down from ⓑ.
(3) Take the point where the two lines cross as ⓒ. This point ⓒ gives the value when converting
from millimeters to inches. Therefore, 55mm = 2.165 inches.

2. Convert 550mm into inches.

(1) The number 550 does not appear in the table, so divide by 10(Move the decimal point one place
to the left) to convert it to 55mm.
(2) Carry out the same procedure as above to convert 55mm to 2.165 inches.
(3) The original value(550mm) was divided by 10, so multiply 2.165 inches by 10(Move the decimal
point one place to the right) to return to the original value.
This gives 550mm = 21.65 inches.

BEWARE OF EXHAUST FUMES
Prevent asphyxiation. Engine exhaust fumes
can cause sickness or death.
If you must operate in a building, be positive
there is adequate ventilation. Either use an
exhaust pipe extension to remove the exhaust
fumes or open doors and windows to bring
enough outside air into the area.
REMOVE PAINT BEFORE WELDING OR
HEATING
Avoid potentially toxic fumes and dust.
Hazardous fumes can be generated when paint
is heated by welding, soldering, or using a torch.
Do all work outside or in a well ventilated area.
Dispose of paint and solvent properly.
Remove paint before welding or heating:
· If you sand or grind paint, avoid breathing the 13031GE14

dust.
Wear an approved respirator.
·If you use solvent or paint stripper, remove
stripper with soap and water before welding.
Remove solvent or paint stripper containers
and other flammable material from area.
Allow fumes to disperse at least 15 minutes
before welding or heating.

ILLUMINATE WORK AREA SAFELY

Illuminate your work area adequately but safely.
Use a portable safety light for working inside or
under the machine. Make sure the bulb is
enclosed by a wire cage. The hot filament of
an accidentally broken bulb can ignite spilled
fuel or oil.

13031GE15

1-5
SERVICE MACHINE SAFELY
Tie long hair behind your head. Do not wear a
necktie, scarf, loose clothing or necklace when
you work near machine tools or moving parts.
If these items were to get caught, severe injury
could result.
Remove rings and other jewelry to prevent
electrical shorts and entanglement in moving
parts. 13031GE16

STAY CLEAR OF MOVING PARTS

Entanglements in moving parts can cause
serious injury.
To prevent accidents, use care when working
around rotating parts.

13031GE17
