THE  RIVING  KNIFE  AND  ITS  ADJUSTMENT: 

The  riving  knife  (see  adiacent  sketch)  is  an  important  safety 

device  on  a  circular  saw.  It  prevents  the  saw  kerf  "closing 
up"  which  could  cause  the  wood  to  "kick  back".  The  riving 
knife  will  be  correctly  adiusted  when  it  is  5/64"  - 3/32" 
clear  of  the  tips  of  the  teeth  on  the  saw  blade.  The  riving 

knife  is  secured  by  clamping  bolts. 

The  circular-saw  cover  plate  should  be  removed  to  enable  the 

riving knife  to  be  adjusted. 

OPERA Tl NG  OF  THE  CIRCULAR  SAW: 

The  machine  must  be  tilted to  the  "circular-saw"  position. 
The  ball  handle  (see  sketch)  is  pulled away  from  the  motor 

to  engage  the  clutch.  The  clutch  dogs  will  engage  more 
easily  if  the  sanding  disc  is  turned  by  hand. 
The  switch  is  moved  through

Position  2

(3000 

r. p. m. )  . 

The  clutch  must  never  be  engaged  or  disengaged  while  the 

motor  is  running. 

SAFETY  PRECAUTIONS: 

circular-saw 

· band-saw  pos1ii:;;;s

l. Always  use  saw  blades  in  perfect  condif'ion  and  free  from

cracks  (i.e.  properly  sharpened  and  set).

2. The  saw  blade  must  be  firmly  clamped  on  the  saw  spindle  and  its teeth  must  point  in the  correct

direction.

3. The  blade  projection  should  be  adjusted  to  suit  the  thickness  of  the  material  to  be  cul'.

4. The  riving  knife  must  always  be  used  and  should  never  be  removed.

5. The  saw  guard should always  be  set as  low  as  possible.

6. The  feed  should  be adapted  to  suit  the  material  being  worked.
7. Loose knots  should  be  knocked  out  before  sawing  to  avoid  the  danger  of  the  wood  kicking  back.

RIP-SAWING  WITHOUT  A  FENCE: 
The  coarse-tooth  blade  should  be  used  for  rip-sawing.  To 
prevent  the wood  binding  on the saw,  a  curved  piece 
must  be  laid  with  the  convex  side  resting  on  the  table. 

The  cut  pieces  will  then  fall  away  from  the  blade 

(Sketch  5) . 

RIP-SAWING  WITH  FENCE: 
Material  can  be  cut 

accurately  to  width 

only  if  one edge  is 
first  trued  up (Sketch 6). 

The  fence  is then 

set  to  the required 
dimension  as shown 
on  the  scale  marked 

on  the  saw  table
