Maintenance; Adjusting The Cutting Angle - Makita LH1040 Original Instruction Manual

dangerous kickbacks.
NEVER remove cut-off material while the blade is
•
running.
NEVER place your hands or fingers in the path of
•
the saw blade.
Always secure the rip fence firmly, or dangerous
•
kickbacks may occur.
Always use "work helpers" such as push sticks and
•
push blocks when cutting small or narrow
workpieces, or when the ado head is hidden from
view while cutting.
Work helpers
Push sticks, push blocks or auxiliary fence are types of
"work helpers". Use them to make safe, sure cuts
without the need for the operator to contact the blade
with any part of the body.
Push block
Fig.44
Use a 15 mm piece of plywood.
Handle should be in center of plywood piece. Fasten
with glue and wood screws as shown. Small piece 10
mm x 9 mm x 30 mm of wood must always be glued to
plywood to keep the blade from dulling if the operator
cuts into push block by mistake.
(Never use nails in push block.)
Auxiliary fence
Fig.45
Fig.46
Make auxiliary fence from 10 mm and 15 mm plywood
pieces.
Remove the rip fence, clamping screw (A), flat washer
and square nut from the rip fence holder and then attach
and secure the auxiliary fence to the rip fence holder by
using a bolt M6 longer than M6x50, washers and nut.
Ripping
CAUTION:
When cutting long or large workpieces, always
•
provide adequate support behind the table. DO
NOT allow a long board to move or shift on the
table. This will cause the blade to bind and
increase the possibility of kickback and personal
injury. The support should be at the same height as
the table.
1. Adjust the depth of cut a bit higher than the
thickness of the workpiece. To make this
adjustment, loosen two levers and lower or raise
the top table.
2. Position the rip fence to the desired width of rip
and secure in place by tightening the clamping
screw (A). Before ripping, make sure the two
screws of the rip fence holder are secured. If it is
not secured enough, retighten it.
3. Turn the tool on and gently feed the workpiece
into the blade along with the rip fence.
(1) When the width of rip is 40 mm or wider, use
a push stick.
Fig.47
(2) When the width of rip is narrower than 40 mm,
the push stick cannot be used because the
push stick will strike the top blade guard. Use
the auxiliary fence and push block.
Install securely the auxiliary fence which is
secured to the rip fence holder on the table.
Feed the workpiece by hand until the end is
about 25 mm from the front edge of the top
table. Continue to feed using the push block
on the top of the auxiliary fence until the cut is
complete.

Carrying tool
Fig.49
Make sure that the tool is unplugged. Secure the blade
at 0° bevel angle and the turn base at left miter angle
fully. Lower the handle fully and lock it in the lowered
position by fully pushing in the stopper pin.
Carry the tool by holding both sides of the tool base as
shown in the figure. If you remove the holders, dust bag,
etc., you can carry the tool more easily.

CAUTION:
Always secure all moving portions before carrying
•
the tool.

MAINTENANCE

CAUTION:
Always be sure that the tool is switched off and
•
unplugged before attempting to perform inspection
or maintenance.
Never use gasoline, benzine, thinner, alcohol or
•
the like. Discoloration, deformation or cracks may
result.
WARNING:
Always be sure that the blade is sharp and clean
•
for the best and safest performance.

Adjusting the cutting angle

This tool is carefully adjusted and aligned at the factory,
but rough handling may have affected the alignment. If
your tool is not aligned properly, perform the following:
1. Miter angle
Fig.51
Loosen the grip which secures the turn base. Turn
the turn base so that the pointer points to 0° on the
miter scale. Tighten the grip and loosen the hex
bolts securing the guide fence using the socket
wrench.
Lower the handle fully and lock it in the lowered
position by pushing in the stopper pin. Square the
