Maintenance - Makita 4334D Instruction Manual

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.
