HEAD RAISE LIMIT SENSING ARM

 1. 

The  sensing  arm  works  in  conjunction  with  the 

head clear proximity switch 

(3 PRS)

 to assure that 

the saw head has raised sufficiently above existing 

stock so that automatic indexing (or manual stock 

positioning) can be accomplished safely.

Head Raise Limit Sensing Arm.

Sensng Arm Operaton When the Saw Head Rases 

    

 

 

1. 

The saw head lifts the sensing arm above the stock 

at a rapid rate (there is no slow head raising rate) 

until it actuates the head clear proximity switch 

(3 

PRS)

.  This causes saw head upward movement 

to stop when the blade is approximately one (1) 

inch (25.4 mm) above the stock.  This clearance 

anticipates potentially crooked and/or out-of-round 

stock being used.

2. 

If operating in automatic mode, the fixed vise then 

unclamps, and stock is indexed forward.  Following 

the advance of stock, the fixed vise clamps and the 

index vise unclamps.

3. 

When the fixed vise unclamps prior to indexing, its 

jaws open just enough to allow stock advancement.  

The vise jaws can be opened wider only when the 

saw head has been manually raised to the full "up" 

position to actuate the head up proximity switch 

(2 

PRS)

. This assures that the left saw guide arm will 

clear the fixed vise when it opens to receive larger 

stock.

 

Left saw gude arm adjustment for stock wdth 

must be made manually by the operator.

Sensng Arm Operaton When the Saw Head Lowers

1. 

The saw head lowers until stock is contacted by the 

sensing arm. 

2. 

Sensing arm contact with the stock is maintained 

throughout the cut.  After a cut has been finished:  

(a)

  The  head  down  proximity  switch 

(5  PRS)

  is 

actuated; 

(b)

 The saw head raises.

VISE JAW ADJUSTMENT

1. 

The distance between the fixed (right) and movable 

(left) vise jaws can be adjusted to accommodate 

varying stock widths.  To adjust, scroll through the 

screens  until  the  INDEX  VISE  and  FIXED  VISE 

controls are displayed.  Then press the

 

desired key 

to open or clamp the vise jaws.

 

The hydraulcs MUST be "on", the operaton 

mode MUST be n "manual" for the vse con-

trols to operate.

2. 

For  index  lengths  between  .50  and  1.75  inches 

(12.7 and 44.4 mm), replace standard serrated wear 

plate on the movable jaw of the outboard vise with 

a recessed wear plate (box of extra parts).

MATERIAL INDEXING

1. 

Your machine is capable of a 16 inch (406.4 mm) 

single  stroke  index  (minimum  is  0.50  inch  (12.7 

mm). It can also is capable of a 10X multiple index 

up  to  a  maximum  length  of  160  inches  (4064.0 

mm).

2. 

A movable roller assembly to help support the mate-

rial is located behind the index vise.  It is connected 

to the index vise by a rod that allows the roller to 

move with the movement of the index vise.

3. 

Index length is set in the JOB ENTRY screen which 

is on the first screen . Press the 

"6"

 key on the 

numeric keypad to access this screen.
