Maintenance - Makita 4322 Instruction Manual

Cutouts
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
12 mm or more in diameter. Insert the blade into this
hole to start your cut. (Fig. 13)
B) Plung 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.(Fig. 14)
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 pierces the workpiece, slowly lower
the base of the tool down onto the workpiece sur-
face.
4. Complete the cut in the normal manner.
Finishing edges (Fig. 15)
To trim edges or make 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.
Dust extraction (Fig. 16)
Clean cutting operations can be performed by connecting
this tool to a Makita vacuum cleaner. Insert the hose of
the vacuum cleaner into the hole at the rear of the tool.
Lower the dust cover before operation.
CAUTION:
Dust extraction cannot be performed when making bevel
cuts.
Rip fence set (optional accessory)
CAUTION:
Always be sure that the tool is switched off and
unplugged before installing or removing accessories.
1) Straight cuts (Fig. 17 & 18)
When repeatedly cutting widths of 160 mm or less,
use of the rip fence will assure fast, clean, straight
cuts. To install, insert the rip fence into the rectangu-
lar hole on the side of the tool base with the fence
guide facing down. Slide the rip fence to the desired
cutting width position, then tighten the bolt to secure
it.
2) Circular cuts (Fig. 19 & 20)
When cutting circles or arcs of 170 mm or less in
radius, install the rip fence as follows.
Insert the rip fence into the rectangular hole on the
side of the tool base with the fence guide facing up.
Insert the circular guide pin through either of the two
holes on the fence guide. Screw the threaded knob
onto the pin to secure the pin. Now slide the rip
fence to the desired cutting radius, and tighten the
bolt to secure it in place. Then move the tool base all
the way forward.
Anti-splintering device (optional accessory)
(Fig. 21)
For splinter-free cuts, the anti-splintering device can be
used. To install the anti-splintering device, move the tool
base all the way forward and insert it between the two
protrusions of the tool base.
CAUTION:
The anti-splintering device cannot be used when making
bevel cuts.

MAINTENANCE

CAUTION:
Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
To maintain product safety and reliability, repairs, mainte-
nance or adjustment should be carried out by a Makita
Authorized Service Center.
