Machine Operation - Jet JTS-10 Operating Instructions Manual

6. Machine operation

Correct working position:
In front of the machine standing out
of the line of cutting (danger zone).
Work piece handling:
Hands placed flat on the work piece
outside the cutting area.
Feed the work piece towards the saw
blade in the direction of the saw line.
Push the work piece steadily forward;
complete the cut as a single
movement.
Support long and wide work pieces
with helping roller stands.
Operating hints:
Always observe the safety
instructions and adhere to the
current regulations.
Ensure that the saw blade protective
cover is in the correct position before
you start sawing.
The cutting blade must first reach the
maximum rpm before cutting may
begin.
Attention:
The condition of the blade should be
checked before each machining
process.
Work only with a sharp and flawless
sawblade.
Never use a sawblade rated with a
blade speed lower than the machine.
Use a suitable wedge to prevent
round timber from turning under the
pressure of the cut
Use suitable table extensions and
supporting aids for difficult to handle
work pieces.
Always hold and guide the work
pieces safely during machining.
Do not perform any operation
freehand.
Do not perform any grooving,
tenoning or splitting operations on
this machine.
When ripping narrow work pieces
(width less than 120mm) use a push-
stick or push-wood.
Make sure that small cut off work
pieces will not be caught and thrown
away by the rising saw blade teeth.
Remove cut and jammed work
pieces only when motor is turned off
and the machine is at a complete
standstill.
Pay particular attention on reducing
the risk of kickback.
The supplied raving knife must
always be used.
Inspect for correct adjustments.
For the authorized use of the
machine observe the appendix A

Well tighten the screws with the
supplied allen wrench (C).
7.3 Mounting the saw guard
The saw guard (A, Fig 12) must
always be used.
The saw guard must be lowered to
