Operation; Maintenance - Makita DCS552 Instruction Manual

Blade guard cleaning
When changing the circular saw blade, make sure to
also clean the upper and lower guards of accumulated
metal chips as discussed in the Maintenance section.
Such efforts do not replace the need to check lower
guard operation before each use.

OPERATION

CAUTION:
Always wear eye protection or
goggle before operation.
CAUTION:
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.
CAUTION:
Never twist or force the tool in
the cut. This may cause motor overload and/or a
dangerous kickback, resulting in serious injury to the
operator.
CAUTION:
Always use the circular saw blades
appropriate for your job. The use of inappropriate
circular saw blades may cause a poor cutting perfor-
mance and/or present a risk of personal injury.
CAUTION:
Do not use a deformed or cracked
circular saw blade. Replace it with a new one.
► Fig.12
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 circular saw blade. Set the base on the workpiece
to be cut without the circular saw blade making any
contact. Then turn the tool on and wait until the circular
saw 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 circular saw blade and lead to dangerous
kickback and possible serious injury. Release switch,
wait for the circular saw 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 circular saw
blade and the workpiece whenever the circular saw
blade is set to the maximum depth of cut.

CAUTION:
Do not stack materials when cut-
ting them.
CAUTION:
Do not cut hardened steel, wood,
plastics, concrete, tile, etc. Cut only mild steel,
aluminum and stainless steel with a suitable
circular saw blade.
CAUTION:
Do not touch the circular saw
blade, workpiece or cutting chips with bare hands
immediately after cutting. They may be extremely
hot and could burn your skin.
CAUTION:
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.
Rip fence (Guide rule)
Optional accessory
CAUTION:
Make sure that the rip fence is
securely installed in the correct position before
use. Improper attachment may cause dangerous
kickback.
► Fig.14: 1. Rip fence (Guide rule) 2. Clamping screw
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 posi-
tion with the clamping 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.
CAUTION:
Clean out the upper and lower
guards to ensure there is no accumulated metal
chips which may impede the operation of the
lower guarding system. A dirty guarding system
may limit the proper operation which could result in
serious personal injury. When using compressed
air to blow metal chips out of the guards, wear a
proper eye and breathing protection.
CAUTION:
After each use, clean up the inside
of the dust box and wipe off the saw dust on the
tool. Fine metallic dust may come inside the tool and
cause malfunction or a fire.
NOTICE:
Never use gasoline, benzine, thinner,
alcohol or the like. Discoloration, deformation or
cracks may result.
To maintain product SAFETY and RELIABILITY,
repairs, any other maintenance or adjustment should
be performed by Makita Authorized or Factory Service
Centers, always using Makita replacement parts.
