Operation - Makita BCS550 Instruction Manual

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.

When not in use, store the hex wrench as shown in the

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.

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.

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)

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.
