Maintenance - Makita M4302 Instruction Manual

Bevel cutting (Fig. 8)
CAUTION:
• Always be sure that the tool is switched off and
unplugged before tilting the base.
With the base tilted, you can make bevel cuts at any angle
between 0° and 45° (left or right). (Fig. 4)
Loosen the bolt on the back of the base with the hex
wrench and slide the base backwards. (Fig. 9)
Tilt the base until the desired bevel angle is obtained. The
edge of the housing indicates the bevel angle by
graduations. Then check the contact between the back
edge of the blade and the roller. Now tighten the bolt to
secure the base.
Front flush cuts (Fig. 10)
Loosen the bolt on the back of the base with the hex
wrench and slide the base all the way back. Then tighten
the bolt to secure the base.
Cutouts
Cutouts can be made with either of two methods A or B.
A) Boring a starting hole (Fig. 11)
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.
B) Plunge cutting (Fig. 12)
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
workpiece 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 pierces the workpiece, slowly lower
the base of the tool down onto the workpiece
surface.
(4) Complete the cut in the normal manner.
Finishing edges (Fig. 13)
To trim edges or make dimensional adjustments, run the
blade lightly along the cut edges.
For smoother cutting of plywood or other workpiece with
easily splintered surfaces, transparent tape may be used
over your cutting line.
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
unplugged before attempting to perform inspection or
maintenance.
• Never use gasoline, benzine, thinner, alcohol or the
like. Discoloration, deformation or cracks may result.
Replacing carbon brushes (Fig. 14)
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. (Fig. 15)
To maintain product SAFETY and RELIABILITY, repairs,
any other maintenance or adjustment should be
performed by Makita Authorized Service Centers, always
using Makita replacement parts.
