Operation; Maintenance - Makita DCS550 Instruction Manual

Do not use gasoline, thinner or the like to clean
•
the lens of lamp. Using such substances will
damage the lens.
ASSEMBLY
CAUTION:
Always be sure that the tool is switched off and the
•
battery cartridge is removed before carrying out
any work on the tool.
Removing or installing blade
Fig.7
CAUTION:
Be sure the blade is installed with teeth pointing
•
up at the front of the tool.
Use only the Makita wrench to install or remove
•
the blade.
To remove the blade, press the shaft lock so that the
blade cannot revolve and use the wrench to loosen the
hex bolt counterclockwise. Then remove the hex bolt,
outer flange and blade.
To install the blade, follow the removal procedure in
reverse. BE SURE TO TIGHTEN THE HEX BOLT
CLOCKWISE SECURELY.
Fig.8
When changing blade, make sure to also clean upper
and lower blade guards of accumulated chips and
particles. Such efforts do not, however, replace the
need to check lower guard operation before each use.
Hex wrench storage
Fig.9
When not in use, store the hex wrench as shown in the
figure to keep it from being lost.

OPERATION

CAUTION:
Always insert the battery cartridge all the way until
•
it locks in place. If you can see the red part on the
upper side of the button, it is not locked completely.
Insert it fully until the red part cannot be seen. If
not, it may accidentally fall out of the tool, causing
injury to you or someone around you.
Be sure to move the tool forward in a straight line
•
gently. Forcing or twisting the tool will result in
overheating the motor and dangerous kickback,
possibly causing severe injury.
If the tool is operated continuously until the battery
•
cartridge has discharged, allow the tool to rest for
15 minutes before proceeding with a fresh battery.
Never twist or force the tool in the cut. This may
•
cause motor overload
kickback, resulting in serious injury to the operator.
Always wear eye protection or goggle before operation.

and/or a dangerous
Fig.10
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 the tool, they cannot be cut by
the blade. Set the base on the workpiece to be cut
without the blade making any contact. Then turn the tool
on and wait until the blade attains full speed. Now
simply move the tool forward over the workpiece
surface, keeping it flat and advancing smoothly until the
cutting is completed.
To get clean cuts, keep your cutting 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 particles being
ejected from the tool. Use eye protection to help avoid
injury.
The sight grooves in the base makes it easy to check
the distance between the front edge of the blade and
the workpiece whenever the blade is set to the
maximum depth of cut.
Fig.11
CAUTION:
Do not use a deformed or cracked blade. Replace
•
it with a new one.
Do not stack materials when cutting them.
•
Do not cut hardened steel, stainless steel, wood,
•
plastics, concrete, tile, etc. Cut only mild steel
and aluminum.
Do not touch the blade, workpiece or cutting chips
•
with your bare hand immediately after cutting, they
may be extremely hot and could burn your skin.
Always use the blades appropriate for your job.
•
The use of inappropriate blades may cause a poor
cutting performance and/or present a risk of
personal injury.
Rip fence (guide rule) (Accessory)
Fig.12
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 screw on the front of the base. It also
makes repeated cuts of uniform width possible.

MAINTENANCE

CAUTION:
Always be sure that the tool is switched off and the
•
battery cartridge is removed before attempting to
perform inspection or maintenance.
Never use gasoline, benzine, thinner, alcohol or the
•
like. Discoloration, deformation or cracks may result.
