Carrying Tool; Maintenance; Adjusting The Cutting Angle; After Use - Makita LH1040 Instruction Manual

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 kick-
back 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 thick-
ness 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. 50)
(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. (Fig. 51)

Carrying tool

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. (Fig. 52)
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. (Fig. 53)
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
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. (Fig. 54)
Lower the handle fully and lock it in the lowered position
by pushing in the stopper pin. Square the side of the
blade with the face of the guide fence using a triangular
rule, try-square, etc. Then securely tighten the hex bolts
on the guide fence in the order from the right side.
(Fig. 55)
2. Bevel angle
(1) 0° bevel angle
Lower the handle fully and lock it in the lowered
position by pushing in the stopper pin. Loosen
the lever at the rear of the tool.
Turn the 0° bevel angle adjusting bolt on the
right side of the turn base two or three revolu-
tions clockwise to tilt the blade to the right.
(Fig. 56)
Carefully square the side of the blade with the
top surface of the turn base using the triangular
rule, try-square, etc. by turning the 0° bevel
angle adjusting bolt counterclockwise. (Fig. 57)
Make sure that the pointer on the turn base
point to 0° on the bevel scale on the arm. If it
does not point to 0°, loosen the screw which
secures the pointer and adjust the pointer so
that it will point to 0°. (Fig. 58)
(2) 45° bevel angle
Adjust the 45° bevel angle only after performing
0° bevel angle adjustment. To adjust left 45°
bevel angle, loosen the lever and tilt the blade to
the left fully. Make sure that the pointer on the
arm points to 45° on the bevel scale on the arm.
If the pointer does not point to 45°, turn the 45°
bevel angle adjusting bolt on the left side of the
arm until the pointer points to 45°. (Fig. 59)
Replacing carbon brushes (Fig. 60 & 61)
Remove and check the carbon brushes regularly.
Replace when they wear down to the limit mark. Keep
the carbon brushes clean and free to slip in the holders.
Both carbon brushes should be replaced at the same
time. Use only identical carbon brushes.
Use a screwdriver to remove the brush holder caps. Take
out the worn carbon brushes, insert the new ones and
secure the brush holder caps.

After use

• After use, wipe off chips and dust adhering to the tool
with a cloth or the like. Keep the blade guards clean
according to the directions in the previously covered
section titled "Blade guard". Lubricate the sliding por-
tions with machine oil to prevent rust.
To maintain product SAFETY and RELIABILITY, repairs,
any other maintenance or adjustment should be per-
formed by Makita Authorized Service Centers, always
using Makita replacement parts.
