Makita BLS820 Manual page 11

18. Hold the handle firmly. Be aware that the saw
moves up or down slightly during start-up and
stopping.
19. Make sure the blade is not contacting the work-
piece before the switch is turned on.
20. Before using the tool on an actual workpiece, let
it run for a while. Watch for vibration or wobbling
that could indicate poor installation or a poorly
balanced blade.
21. Wait until the blade attains full speed before cut-
ting.
22. Stop operation immediately if you notice any-
thing abnormal.
23. Do not attempt to lock the trigger in the on posi-
tion.
24. Be alert at all times, especially during repetitive,
monotonous operations. Don't be lulled into a
false sense of security. Blades are extremely
unforgiving.
25. Always use accessories recommended in this
manual. Use of improper accessories such as
abrasive wheels may cause an injury.
26. Do not use the saw to cut other than wood or
similar materials.
27. Connect miter saws to a dust collecting device
when sawing.
28. Select saw blades in relation to the material to
be cut.
29. Take care when slotting.
30. Replace the kerf board when worn.
Do not use saw blades manufactured from high speed
steel.
Some dust created from operation contains chemicals
known to cause cancer, birth defects or other reproduc-
tive harm. Some examples of these chemicals are:
• lead from lead-based-painted material and,
• arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how
often you do this type of work.
To reduce your exposure to these chemicals: work in a
well ventilated area and work with approved safety equip-
ment, such as those dust masks that are specially
designed to filter out microscopic particles.
To reduce the emitted noise, always be sure that the
blade is sharp and clean.
The operator is adequately trained in the use, adjustment
and operation of the machine.
Use correctly sharpened saw blades. Observe the maxi-
mum speed marked on the saw blade.
Refrain from removing any cut-offs or other parts of the
workpiece from the cutting area whilst the machine is
running and the saw head is not in the rest position.
SAVE THESE INSTRUCTIONS.
OPERATING INSTRUCTIONS
Installing auxiliary plate
Always installing the auxiliary plate using the notch in the
tool's base and secure it by tightening the hex bolt before
operation.
(Fig. 1 & 2)
Installing or removing battery cartridge (Fig. 3)
• Always switch off the tool before insertion or removal of
the battery cartridge.
• To remove the battery cartridge, withdraw it from the
tool while sliding the button on the side of the cartridge.
• To insert the battery cartridge, align the tongue on the
battery cartridge with the groove in the housing and slip
it into place. Always insert it all the way until it locks in
place with a little click. If not, it may accidentally fall out
of the tool, causing injury to you or someone around
you.
• Do not use force when inserting the battery cartridge. If
the cartridge does not slide in easily, it is not being
inserted correctly.
Socket wrench (Fig. 4)
The socket wrench is stored as shown in Fig. 4. When
using the socket wrench, pull it out of the wrench holder.
After using the socket wrench, return it to the wrench
holder.
Bench mounting saw (Fig. 5 & 6)
When the tool is shipped, the handle is locked in the low-
ered position by the stopper pin. Release the stopper pin
by lowering the handle slightly and pulling the stopper
pin.
This tool should be bolted with four bolts to a level and
stable surface using the bolt holes provided in the tool's
base. This will help prevent tipping and possible injury.
Installing or removing saw blade
CAUTION:
• Always be sure that the tool is switched off and the bat-
tery cartridge is removed before installing or removing
the blade.
• Use only the Makita socket wrench provided to install
or remove the blade. Failure to do so may result in
overtightening or insufficient tightening of the hex bolt.
This could cause serious injury to operator or others in
the general vicinity of the tool.
Lock the handle in the raised position by pushing in the
stopper pin. (Fig. 5)
To remove the blade, use the socket wrench to loosen
the hex bolt holding the center cover by turning it coun-
terclockwise. Raise the safety cover and center cover.
(Fig. 7)
Press the shaft lock to lock the spindle and use the
socket wrench to loosen the hex bolt (left-handed) clock-
wise. Then remove the hex bolt, outer flange and blade.
(Fig. 8)
To install the blade, mount it carefully onto the spindle,
making sure that the direction of the arrow on the surface
of the blade matches the direction of the arrow on the
blade case. Install the outer flange and hex bolt, and then
use the socket wrench to tighten the hex bolt (left-
handed) securely counterclockwise while pressing the
shaft lock. (Fig. 9 & 10)
CAUTION:
For all countries other than European countries
The inner flange has a 25 mm diameter on one side and
a 25.4 mm diameter on the other. The side with 25.4 mm
diameter is marked by "25.4". Use the correct side for the
hole diameter of the blade you intend to use. Mounting
the blade on the wrong side can result in dangerous
vibration.
