Makita LH1040 Instruction Manual page 15

Press the shaft lock to lock the spindle, use the socket
wrench to loosen the hex bolt clockwise. Then remove the
hex bolt, outer flange and blade. (Fig. 17)
To install the blade, mount it carefully onto the spindle,
making sure that the direction of the arrow on the surface
of the blade matches the direction of the arrow on the
blade case. Install the outer flange and hex bolt, and then
use the socket wrench to tighten the hex bolt (left-handed)
securely counterclockwise while pressing the shaft lock.
(Fig. 18 & 19)
NOTE:
• When installing a saw blade, be sure to insert it from
the outside of the blade guard B at first and then raise it
so that the blade is finally placed in the blade guard B.
For all countries other than European countries
(Fig. 20)
CAUTION:
• The silver ring 25.4 mm in outer diameter is factory-
installed onto the spindle. The black ring 25 mm in
outer diameter is included as standard equipment.
Before mounting the blade onto the spindle, always be
sure that the correct ring for the arbor hole of the blade
you intend to use is installed onto the spindle.
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 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 (Fig. 21)
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.
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. 22)
The riving knife has been installed before shipment from
the factory so that the blade and riving knife are in a
straight line. (Fig. 23)
CAUTION:
• If the blade and riving knife are not aligned properly, a
dangerous pinching condition may result during
operation. 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 Makita authorized service center repair it.
Installing and adjusting rip fence (Fig. 24)
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 thickness of
the workpiece.
After adjusting the rip fence, tighten the clamping
screw (A) firmly. (Fig. 25)
NOTE:
• There are four patterns to position the rip fence as
shown in the figure. 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. (Fig. 26)
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
position 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. 27)
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 distance (A) and (B)
between the rip fence and blade. Take both
measurements using the tooth marked with the crayon.
These two measurements should be identical If the rip
fence is not parallel with the blade, proceed as follows:
(Fig. 28)
(1) Turn two adjusting screws counterclockwise.
(Fig. 29 & 30)
(2) Shift the back edge of the rip fence slightly to right
or left until it becomes parallel with the blade.
(3) Tighten the two screws on the rip fence firmly.
