is slippery. Do not drop the machine on your feet while lifting!
3.2 Installation
• Put the machine in a place free from moisture. Put the machine in a place free from moisture.
• Put the machine on a flat surface without play or on a flat work bench. Put the machine on a flat surface without play or on a flat work bench.
• Secure a sufficient space around the machine. A wide space is necessary particularly when Secure a sufficient space around the machine. A wide space is necessary particularly when
working with long and heavy pipe.
• It is mandatory to use the Pipe Support for long and heavy pipe. Avoid excessive force applied It is mandatory to use the Pipe Support for long and heavy pipe. Avoid excessive force applied
to the machine which causes it to tilt.
• Make sure that the power source is equipped with a ground fault circuit breaker to avoid Make sure that the power source is equipped with a ground fault circuit breaker to avoid
electric shock.
• Use an earth clip when a power receptacle without a base for grounding is used (*1). Use an earth clip when a power receptacle without a base for grounding is used ( 1).
• When an extension cord is used, use the one conforming to the applicable regulations (*2). When an extension cord is used, use the one conforming to the applicable regulations ( 2).
*1 Confirmation of earth (grounding) and earth leakage circuit breaker: Before starting use of the 1 Confirmation of earth (grounding) and earth leakage circuit breaker: Before starting use of the
machine, make sure that the power supply to which this machine will be connected is fitted with
an earth leakage circuit breaker for prevention of electric shock which conforms to the occupatio-
nal safety and health law, electrical equipment technical standard, etc.
Always ground this machine. It is recommended to ground the machine for your own safety if it Always ground this machine. It is recommended to ground the machine for your own safety if it
is used with a power supply which is fitted with a current-operated earth leakage circuit breaker
having the rated sensitivity current of 15 mA max. and the operating time of 0.1 seconds max.
When the receptacle used does not have a ground slot, the earth clip and earth (ground) wire,
When the receptacle used does not have a ground slot, the earth clip and earth (ground) wire,
confirm that they are without fault.
When you have a tester or an insulation resistance meter, check for continuity between the earth When you have a tester or an insulation resistance meter, check for continuity between the earth
clip and the machine’s metal frame. Grounding work (for example, burying the earth pole (earth
plate, earth bar) in the ground and connecting the earth (ground) wire must be done by a quali-
fied electrician.
*2 Extension Cord: When an extension cord is required for use with a distant power supply, is 2 Extension Cord: When an extension cord is required for use with a distant power supply, is
should be thick enough to carry a current and as possible to ensure that the product is used with
the maximum efficiency without a failure. The extension cord used must be a three-cord cab tyre
cable having one earth (grounding) core.

4.1 Preparing for Operation (Fig. B)
The saw blade selected should have T.P.I. which matches the work piece. For saw blade selection, The saw blade selected should have T.P.I. which matches the work piece. For saw blade selection,
refer to the cutting load chart on the machine or in the instruction manual.
Operate the machine in the cutting load position which matches the work piece. A mismatch
Operate the machine in the cutting load position which matches the work piece. A mismatch
in the T.P.I. of the saw blade or in the cutting load position will lead not only to oblique cutting
capability but also to a damaged saw blade.
• Remove sand, soil, chips, dust etc. on its vice. (Wipe off for the new article with a clean cloth Remove sand, soil, chips, dust etc. on its vice. (Wipe off for the new article with a clean cloth
because the rust prevention oil has painted the upper surface of stock vice.)
• Raise the frame and set the cutting load adjustment knob (1) in a position which matches the Raise the frame and set the cutting load adjustment knob (1) in a position which matches the
work piece as indicated in the cutting load chart (2). (For cutting load adjustment, push down
the cutting load adjustment knob and set the pin in the groove position.)
• Move the blade guide head F (3) about 30 mm away from a work piece, e.g. to the rear end for Move the blade guide head F (3) about 30 mm away from a work piece, e.g. to the rear end for
6 inches. The numerals on the frame give a guideline to set the rear end
of the blade guide head F (4). (For 2, 4 and 6 inches.)
