Functional Description - Makita 4131 Betriebsanleitung

• When blade is binding, or when interrupting a
cut for any reason, release the trigger and hold
the tool motionless in the material until the
blade comes to a complete stop. Never attempt
to remove the tool from the work or pull the
tool backward while the blade is in motion or
kickback may occur. Investigate and take correc-
tive actions to eliminate the cause of blade bind-
ing.
• When restarting a tool in the workpiece, center
the blade in the kerf and check that blade teeth
are not engaged into the material. If blade is
binding, it may walk up or kickback from the work-
piece as the tool is restarted.
• Support large panels to minimise the risk of
blade pinching and kickback. Large panels tend
to sag under their own weight. Supports must be
placed under the panel on both sides, near the line
of cut and near the edge of the panel.
• Do not use dull or damaged blades. Unsharp-
ened or improperly set blades produce narrow kerf
causing excessive friction, blade binding and kick-
back.
• Blade depth and bevel adjusting locking levers
must be tight and secure before making cut. If
blade adjustment shifts while cutting, it may cause
binding and kickback.
• Use extra caution when making a "plunge cut"
into existing walls or other blind areas. The
protruding blade may cut objects that can cause
kickback. For plunge cuts, retract lower guard
using retracting handle.
10. Check lower guard for proper closing before
each use. Do not operate the tool if lower guard
does not move freely and close instantly. Never
clamp or tie the lower guard into the open posi-
tion. If tool is accidentally dropped, lower guard may
be bent. Raise the lower guard with the retracting
lever and make sure it moves freely and does not
touch the blade or any other part, in all angles and
depths of cut.
To check lower guard, open lower guard by hand,
then release and watch guard closure. Also check to
see that retracting handle does not touch tool hous-
ing. Leaving blade exposed is VERY DANGEROUS
and can lead to serious personal injury.
11. Check the operation and condition of the lower
guard spring. If the guard and the spring are not
operating properly, they must be serviced before
use. Lower guard may operate sluggishly due to
damaged parts, gummy deposits, or a build-up of
debris.
12. Lower guard should be retracted manually only
for special cuts such as "plunge cuts" and
"compound cuts." Raise lower guard by retract-
ing handle and as soon as blade enters the
material, the lower guard must be released. For
all other sawing, the lower guard should operate
automatically.
13. Always observe that the lower guard is covering
the blade before placing tool down on bench or
floor. An unprotected, coasting blade will cause the
tool to walk backwards, cutting whatever is in its
path. Be aware of the time it takes for the blade to
stop after switch is released.
14. Do not stop the blades by lateral pressure on the
blade.
15. DANGER:
Do not attempt to remove cut material when
blade is moving.
CAUTION:
Blades coast after turn off.
16. Place the wider portion of the tool base on that
part of the workpiece which is solidly supported,
not on the section that will fall off when the cut is
made.
17. Never attempt to make a cut with the tool held
upside down in a vise. This is extremely danger-
ous and can lead to serious accidents.
18. Wear safety goggles and hearing protection dur-
ing operation.
19. Always use blades recommended in this manual.
Do not use any abrasive wheels.
SAVE THESE INSTRUCTIONS.
WARNING:
DO NOT let comfort or familiarity with product
(gained from repeated use) replace strict adherence
to safety rules for the subject product. MISUSE or
failure to follow the safety rules stated in this instruc-
tion manual may cause serious personal injury.

FUNCTIONAL DESCRIPTION

CAUTION:
• Always be sure that the tool is switched off and
unplugged before adjusting or checking function on the
tool.
Adjusting the depth of cut (Fig. 1)
Loosen the lever on the depth guide and move the base
up or down. At the desired depth of cut, secure the base
by tightening the lever.
CAUTION:
• After adjusting the depth of cut, always tighten the lever
securely.
Sighting (Fig. 2)
When cutting, align the A position on the front of the base
with your cutting line on the workpiece.
Switch action (Fig. 3)
CAUTION:
• Before plugging in the tool, always check to see that
the switch trigger actuates properly and returns to the
"OFF" position when released.
To prevent the switch trigger from being accidentally
pulled, a lock-off button is provided.
To start the tool, push in the lock-off button and pull the
switch trigger. Release the switch trigger to stop.
