Adjusting Riving Knife - Makita LH1200FL Manual De Instrucciones

For European countries
CAUTION:
• The ring 30 mm in outer diameter is factory-installed
between the inner and outer flanges.
Return the lower blade guard A and center cover to its
original position. Then tighten the hex bolt clockwise to
secure the center cover. Raise the lower blade guard B
as far as it will go and tighten the clamping screw firmly
while holding it in the raised position. Lower the handle to
make sure that the lower blade guards move properly.
Make sure shaft lock has released spindle before making
cut.

Adjusting riving knife

Before adjusting the riving knife, loosen the two levers by
turning counterclockwise and press the top table on the
right side nearby the riving knife to its lowered position.
Then secure the top table by firmly re-tightening the two
levers as shown in the figure. (Fig. 19)
There must be a clearance of about 4 – 5 mm between
the riving knife and the blade teeth. Adjust the riving knife
accordingly by loosening two hex bolts counterclockwise
with the hex socket wrench and measuring the distance.
Tighten the hex bolts securely, and then check to see
that the top blade guard works smoothly before cutting.
(Fig. 20)
The riving knife has been installed before shipment from
the factory so that the blade and riving knife are in a
straight line. (Fig. 21)
CAUTION:
• If the blade and riving knife are not aligned properly, a
dangerous pinching condition may result during opera-
tion. Make sure the riving knife is positioned between
both outer ends of the blade teeth when viewing from
the top. You could suffer serious personal injury while
using the tool without a properly aligned riving knife. If
they are not aligned for any reasons, always have Mak-
ita authorized service center repair it.
• Don't remove the riving knife.
Installing and adjusting rip fence
1. Install the rip fence on the table so that the rip fence
holder engages with the guide rail. Tighten the
clamping screw (B) of the rip fence firmly clockwise.
2. Loosen the clamping screw (A).
3. Slide the rip fence and secure it so that the far end
from you of the rip fence is aligned with the point at
which the front edge of saw blade just appears from
top surface of the workpiece. The purpose of this
adjustment is to reduce risk of kick-back toward
operator that cut piece from the workpiece is
pinched between the saw blade and rip fence and
finally pushed out toward operator. The line 3 varies
by thickness of workpiece or the table level. Adjust
the position of the rip fence according to the thick-
ness of the workpiece.
After adjusting the rip fence, tighten the clamping
screw (A) firmly. (Fig. 22 & 23)
NOTE:
• The rip fence must be mounted the left side of the saw
blade when in the miter saw mode. (Fig. 24)
16
NOTE:
• There are four patterns to position the rip fence as
shown in the figure. (Fig. 25) Rip fence has two slits on
its sides, one slit with an elevated fringe nearby on the
same side and the other without it. Use the surface of
rip fence with this fringe facing the workpiece only
when cutting off into a piece of a thin workpiece.
NOTE:
• To change the rip fence pattern, remove the rip fence
from the rip fence holder by loosening the clamping
screw (A) and change the facing of the rip fence to the
rip fence holder so that the rip fence faces the rip fence
holder according to your work as shown in the figure.
Insert the square nut on the rip fence holder into the
back end of either slit of the rip fence so that they fit as
shown in the figure.
To change from the pattern A or B to the pattern C or D,
or in adverse case, remove the square nut, washer and
clamping screw (A) from the rip fence holder, then posi-
tion the clamping screw (A), washer and square nut on
the opposite position of the rip fence holder compared
to the original position. Tighten the clamping screw (A)
securely after inserting the square nut of the rip fence holder into the rip fence slit.
Insert the square nut on the rip fence holder into the
back end of either slit of the rip fence so that they fit as
shown in the figure. (Fig. 26)
The rip fence is factory adjusted so that it is parallel to
the blade surface. Make sure that it is parallel. To check
to be sure that the rip fence is parallel with the blade.
Lower the table to the lowest position so that the blade
appears at the topmost position from the table. Mark
one of the blade teeth with a crayon. Measure the dis-
tance (A) and (B) between the rip fence and blade.
Take both measurements using the tooth marked with
the crayon. (Fig. 27) These two measurements should
be identical. If the rip fence is not parallel with the
blade, proceed as follows: (Fig. 28)
(1) Turn the adjusting screws counterclockwise.
(2) Shift the back edge of the rip fence slightly to right
or left until it becomes parallel with the blade.
(3) Tighten the adjusting screw on the rip fence firmly.
CAUTION:
• Be sure to adjust the rip fence so that it is parallel with
the blade, or a dangerous kickback condition may
occur.
• Be sure to adjust the rip fence so that it does not con-
tact the top blade guard or saw blade. (Fig. 29)
Dust bag
The use of the dust bag makes cutting operations clean
and dust collection easy. To attach the dust bag, fit it onto
the dust nozzle. (Fig. 30)
NOTE:
• In miter saw mode, always insert the dust bag to the
back nozzle only.
When the dust bag is about half full, remove the dust bag
from the tool and pull the fastener out. Empty the dust
bag of its contents, tapping it lightly so as to remove par-
ticles adhering to the insides which might hamper further
collection. (Fig. 31)
