Maintenance - Makita 4334d Instruction Manual

Bevel cutting (Fig. 21 & 22)
CAUTION:
Always remove the battery from the tool before making
any adjustments.
With the base tilted, you can make bevel cuts at any
angle between 0° and 45° (left or right). Loosen the base
securing lever and move the base so that the dent mark
in the motor housing is aligned with the slot in the base.
Tilt the base until the desired bevel angle is obtained.
The edge of the motor housing indicates the bevel angle
by graduations. The tighten the base securing lever to
secure the base.
NOTE:
Always remove the plastic cover (chip shield) from the
tool when you make bevel cuts using an optional guide
rule (rip fence) or circular guide.
Flush cutting (Fig. 23)
Loosen th base securing lever and slide the base all the
way back. Then tighten the base securing lever to secure
the base.
Cutouts (Fig. 24 & 25)
Cutouts can be made with either of two methods A or B.
A) Boring a starting hole:
For internal cutouts without a lead-in cut from an
edge, pre-drill a starting hole more than 12 mm in
diameter. Insert the blade into this hole and hold the
tool firmly against the workpiece to start your cut.
B) Plunge cutting:
You need not bore a starting hole or make a lead-in
cut if you carefully do as follows.
1. Tilt the tool up on the front edge of the base, with
the blade point positioned just above the work-
piece surface.
2. Apply pressure to the tool so that the front edge of
the base will not move when you switch on the
tool and gently lower the back end of the tool
slowly.
3. As the blade slices into the workpiece, slowly
lower the base of the tool down onto the work-
piece surface.
4. Complete the cut in the normal manner.
Finishing edges (Fig. 26)
To trim edges or make slight dimensional adjustments,
run the blade lightly along the cut edges.
Metal cutting
Always use a suitable coolant (cutting oil) when cutting
metal. Failure to do so will cause significant blade wear.
The underside of the workpiece can be greased instead
of using a coolant.

MAINTENANCE

CAUTION:
Always be sure that the tool is switched off and the bat-
tery cartridge is removed before carrying out any work on
the tool.
Cleaning clamp on blade holder
If chips or foreign matter get into the clamp on the blade
holder, clean out the clamp after removing it from the
blade holder.

Removing clamp
1. Push the blade installing lever in the (1) direction to
release it. (Fig. 27)
2. Pull the blade installing lever in the (2) direction until
it stops with a little click. If you have difficulty pulling
it out, try to do so while moving it back and forth in
the (3) direction.
3. Rotate the blade installing lever in the (4) direction
until it stops. The clamp will protrude from the blade
holder. (Fig. 28 & 29)
4. Remove the clamp from the blade holder while rotat-
ing the clamp in the (5) direction. (Fig. 30)
Installing clamp
1. Make sure that the blade installing lever has been
rotated in the (4) direction until it stops. (Fig. 31)
2. Insert the clamp into the blade holder while rotating
it in the (6) direction one quarter to one full turn so
that its slot will face forward. (Fig. 32)
CAUTION:
Do not rotate the clamp more than one full turn when
inserting in into the blade holder. If you do so, the
blade may not be tightened firmly.
3. Grasp the clamp with your fingers so that it will not
turn, then rotate the blade installing lever in the (7)
direction until it stops. The clamp will go in the blade
holder. (Fig. 33)
Replacing carbon brushes (Fig. 34 & 35)
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.
To maintain product safety and reliability, repairs, mainte-
nance or adjustment should be carried out by a Makita
Authorized Service Center.
