Maintenance - Makita SP6000 Instruction Manual

overheating the motor and dangerous kickback,
possibly causing severe injury.
• Never approach any part of your body under the tool
base when section cutting, especially at starting. Doing
so may cause serious personal injuries. The blade is
exposed under the tool base.
Hold the tool firmly. The tool is provided with both a front
grip and rear handle. Use both to best grasp the tool. If
both hands are holding saw, they cannot be cut by the
blade. Set the front of base on the workpiece to be cut
without the blade making any contact. Then push in the
lock-off button and turn the tool on and wait until the blade
attains full speed. Now press down the saw head slowly to
the preset depth of cut and simply move the tool forward
over the workpiece surface, keeping it flat and advancing
smoothly until the sawing is completed.
To get clean cuts, keep your sawing line straight and your
speed of advance uniform. If the cut fails to properly follow
your intended cut line, do not attempt to turn or force the
tool back to the cut line. Doing so may bind the blade and
lead to dangerous kickback and possible serious injury.
Release switch, wait for blade to stop and then withdraw
tool. Realign tool on new cut line, and start cut again.
Attempt to avoid positioning which exposes operator to
chips and dust being ejected from saw. Use eye
protection to help avoid injury. (Fig. 24)
When using with guide rail (accessory)
(Fig. 25)
Place the tool on the rear end of guide rail. Turn two
adjusting screws on the tool base so that the tool slides
smoothly without a clatter. Hold the tool firmly. The tool is
provided with both a front grip and rear handle. Use both
to best grasp the tool. Turn on the tool, press down the
tool to the preset depth of cut and cut the splinterguard
along the full length with a stroke. The edge of the
splinterguard corresponds to the cutting edge.
When bevel cutting with the guide rail, slide the slide lever
on the tool base so that the tool does not fall down on its
side. (Fig. 26)
Move the slide lever on the tool base in the direction of
arrow so that it engages the undercut groove in the guide
rail.
Rip fence (guide rule) (Optional
accessory) (Fig. 27)
The handy rip fence allows you to do extra-accurate
straight cuts. Simply slide the rip fence up snugly against
the side of the workpiece and secure it in position with the
screws on the front and the back of the base. It also
makes repeated cuts of uniform width possible.
Overturning the rip fence (guide rule) also works as a sub
base for the tool.
Plunge cutting (Cutting-out) (Fig. 28)
WARNING:
• To avoid a kickback, be sure to observe the following
instructions.
When using the tool without guide rail
Place the tool on the workpiece with the rear edge of tool
base against a fixed stop or equivalent which is devised
by an operator.

When using the tool with guide rail
Place the tool on the guide rail with the rear edge of tool
base against a fixed stop or equivalent which is clamped
on the guide rail.
Hold the tool firmly with one hand on the front grip and the
other on the tool handle. Then push in the lock-off button
and turn the tool on and wait until the blade attains full
speed. Now press down the saw head slowly to the preset
depth of cut and simply move the tool forward to the
desired plunge position.
NOTE:
• The markings on the side of the blade guard show the
front and rear cutting points of the saw blade (A for
diameter 160 mm and B for diame-ter 165 mm) at the
maximum cutting depth and using the guide rail.
(Fig. 29)
Guide device (accessories)
Use of the miter gauge (accessory) allows exact miter
cuts with angles and fitting works.
Use of the clamp (accessory) ensures firm hold of
workpiece on the table.

MAINTENANCE

CAUTION:
• Always be sure that the tool is switched off and
unplugged before attempting to perform inspection or
maintenance.
• Clean out the guard to ensure there is no
accumulated sawdust which may impede the
operation of the guarding system. A dirty guarding
system may limit the proper operation which could
result in serious personal injury. The most effective
way to accomplish this cleaning is with compressed air.
If the dust is being blown out of the guard, be sure
the proper eye and breathing protection is used.
• Never use gasoline, benzine, thinner, alcohol or the
like. Discoloration, deformation or cracks may result.
Adjusting for accuracy of 90° and 45° cut
(vertical and 45° cut)
This adjustment has been made at the factory. But if it is
off, adjust the adjusting screws with a hex wrench while
inspecting 90° or 45° the blade with the base using a
triangular rule or square rule, etc. (Fig. 30 & 31)
NOTE:
• Adjusting for accuracy of 22.5°, 48° and -1° cut cannot
be performed.
Replacing carbon brushes (Fig. 32)
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. (Fig. 33)
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,
any other maintenance or adjustment should be
