Casals DBS900, Instruction Manual

BLADE GUARD SYSTEM

The lower blade guard, attached to your 
saw, is there for your protection and safety. 
It should never be altered for any reason. If it 
becomes damaged or begins to return slowly 
or sluggishly, do not operate your saw until 
the damage has been repaired or replaced. 
Always leave the guard in its correct operation 
position when using the saw.
  When sawing through a work piece, the lower 
blade guard does not cover the blade on the 
underside of the work piece. Since the blade 
is exposed on the underside of the work piece. 
Always keep your hands and fingers away 
from the cutting area. Any part of your body 
coming in contact with the moving blade will 
result in serious injury.
  Never use this saw when the guard is not op-
erating properly. The guard should be checked 
for correct operation before each use. If you 
drop your saw, check lower blade guard and 
bumper for damage at all depth setting before 
using. NOTE: The guard is operating properly 
when it moves freely and then steadily returns 
to the closed position if the lower blade guard 
does not close freely for no reason, take it 
to your nearest authorized Repair Center for 
service before using it.

STARTING A CUT

1.  Always use your saw correctly.
2.  Always support the work piece near the cut.
3.  Always support the work piece so the cut 

will be on your side.

4.  Always clamp the work piece so it will not 

move during the cut. Before starting a cut, 
draw a guideline along the desired line of 
cut. Then place the front edge of the saw 
blades on that part of the work piece that is 
solidly supported.

5.  Never place the saw on the part of the work 

piece that will fall off when the cut is made.

6.  Always keep the cord away from the cutting 

area. Always place the cord so it does not 
hang up on the work piece when making 
a cut. 
Always maintain control of the saw to make 
sawing safer and easier. Loss of control of 
the saw could cause an accident resulting 
in possible serious injury. 
If the cord hangs up on the work piece 
during a cut, release the trigger switch 
immediately. Unplug the saw and move the 
cord to prevent it from hanging up again. 

Using the saw with a damaged cord could 
result in shocking. Have it replaced before 
using the saw again. 

7.  Slide the on/off switch to start the saw. Al-

ways let the blades reach full speed before 
you begin to cut into the work piece. 
If the blades come in contact with the work 
piece before they reach full speed, it could 
cause the saw to kickback towards you, 
resulting in serious injury.

8.  When making a cut, always use a steady, 

even pressure. Forcing the saw causes 
rough cuts and could shorten the life of the 
saw or cause kickback. 
When sawing through a work piece, the 
lower blade guard does not cover the 
blades. The blades are exposed on the 
underside of the work piece; always keep 
your hands and fingers away from the cut-
ting area. Any part of your body coming in 
contact with the moving blade will result in 
serious injury. 
Whenever you lift your saw from the work 
piece, the blade is exposed on the under 
side of the saw until the lower blade guard 
closes. Always MAKE SURE that the lower 
blade guard is closed before setting the 
saw down on work surface.

9.  Always use the lubricating device (includ-

ed) when cutting aluminum, copper, stain-
less steel & cast iron materials because 
they have a tendency to smear and adhere 
to the blades. 

FEED SPEED

Feed speed is how quickly you push the saw 
blades through the material being cut. The 
correct feed speed is totally determined by 
the hardness and the thickness of the material 
being cut.
Only feed the blades down approximately 3/8”, 
then start cutting.

1.  If feed speed is too slow
2.  The blades will only press down on the 

material rather than cutting it.

3.  The blade edge glides and wears down the 

material.

4.  This will cause a poor cut and will cause 

excessive wear on the blades

5.  If the feed speed is too fast
6.  There is a definite risk that the cut might 

split. The splinter will get bigger and bigger 
eventually break risking serious personal
