Maintenance; Operation - Makita DHS680 Instruction Manual

For tool with the inner flange for a
15.88 mm hole-diameter saw blade
(country specific)
► Fig.21: 1. Mounting shaft 2. Inner flange 3. Saw
blade 4. Outer flange 5. Hex bolt
► Fig.22: 1. Mounting shaft 2. Inner flange 3. Saw
blade 4. Outer flange 5. Hex bolt 6. Ring
Mount the inner flange with its recessed side facing
outward onto the mounting shaft and then place saw
blade (with the ring attached if needed), outer flange
and hex bolt.
BE SURE TO TIGHTEN THE HEX BOLT
COUNTERCLOCKWISE SECURELY.
WARNING:
• Before mounting the blade onto the spin-
dle, always be sure that the correct ring for
the blade's arbor hole you intend to use is
installed between the inner and the outer
flanges. Use of the incorrect arbor hole ring
may result in the improper mounting of the blade
causing blade movement and severe vibration
resulting in possible loss of control during oper-
ation and in serious personal injury.
Hex wrench storage
► Fig.23: 1. Hex wrench
When not in use, store the hex wrench as shown in the
figure to keep it from being lost.
Connecting a vacuum cleaner
(Optional accessory in some countries)
► Fig.24: 1. Dust nozzle 2. Screw 3. Lever
► Fig.25: 1. Vacuum cleaner 2. Hose
When you wish to perform clean cutting operation,
connect a Makita vacuum cleaner to your tool.
Install the dust nozzle on the tool using the screw. Then
connect a hose of the vacuum cleaner to the dust noz-
zle as shown in the figure.
For tool without dust nozzle provided as a standard
equipment, replace the lever fixed on the lower guard to
the one supplied with the dust nozzle (optional acces-
sory) at the same time when installing the dust nozzle.
Otherwise you will not be able to make a cut because
the lower guard movement is hindered by the dust
nozzle.

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 kick-
back, possibly causing severe injury.
• Always use a front grip and rear handle and
firmly hold the tool by both front grip and rear
handle during operations.
► Fig.26
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 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 sawing is com-
pleted.
To get clean cuts, keep your sawing line straight and
your speed of advance uniform. If the cut fails to prop-
erly 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 wood dust being ejected
from saw. Use eye protection to help avoid injury.
Rip fence (Guide rule) (optional
accessory)
► Fig.27: 1. Clamping screw 2. Rip fence (Guide rule)
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 carrying
out any work on the tool.
Clean out the upper and lower guards to
•
ensure there is no accumulated sawdust
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. The most effective way
to accomplish this cleaning is with compressed
air. If the dust is being blown out of the
guards 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 0° and 45°
cut (vertical and 45° cut)
► Fig.28: 1. Adjusting screw for 45° 2. Adjusting
screw for 0°
► Fig.29: 1. Triangular rule
This adjustment has been made at the factory. But if
it is off, adjust the adjusting screws with a hex wrench
while inspecting 0° or 45° the blade with the base using
a triangular rule or square rule, etc. Use the 45° stopper
for adjusting 45° angle.
