Makita JR180D Manual De Instrucciones página 6

CAUTION:
• The battery charger Model DC1801 is for charging Makita battery cartridge. Never use it for other purposes
or for other manufacturer's batteries.
• When you charge a new battery cartridge or a battery cartridge which has not been used for a long period of
time, it may not accept a full charge. This is a normal condition and does not indicate a problem. You can
recharge the battery cartridge fully after discharging it completely and recharging a couple of times.
• If you charge a battery cartridge from a just-operated machine or a battery cartridge which has been left in
a location exposed to direct sunlight or heat for a long time, the charging light may flash in red color. If this
occurs, wait for a while. Charging will begin after the battery cartridge cools. The battery cartridge will cool
faster if you remove the battery cartridge from the battery charger.
• If the charging light flashes alternately in green and red color, a problem exists and charging is not possible.
The terminals on the charger or battery cartridge are clogged with dust or the battery cartridge is worn out or
damaged.
Trickle charge (Maintenance charge)
If you leave the battery cartridge in the charger to prevent spontaneous discharging after full charge, the
charger will switch into its "trickle charge (maintenance charge)" mode and keep the battery cartridge fresh and
fully charged.
Tips for maintaining maximum battery life
1. Charge the battery cartridge before completely discharged.
Always stop machine operation and charge the battery cartridge when you notice less machine power.
2. Never recharge a fully charged battery cartridge.
Overcharging shortens the battery service life.
3. Charge the battery cartridge with room temperature at 10°C – 40°C (50°F – 104°F).
Let a hot battery cartridge cool down before charging it.
Installing or removing saw blade
CAUTION:
• Always be sure that the machine is switched off and
the battery cartridge is removed before installing or
removing the blade.
• Always clean out all chips or foreign matter adher-
ing to the blade, blade clamp and/or slider. Failure
to do so may cause insufficient tightening of the
blade, resulting in a serious injury.
To install the blade, push the push button in the
direction of the arrow and insert the blade into the
blade clamp as far as it will go. Then release the push
button and make sure that the blade cannot be
extracted even though you try to pull it out. (Fig. 5)
CAUTION:
If you release the push button without inserting the
blade deep enough, the blade may be ejected unex-
pectedly during operation. This can be extremely
dangerous.
To remove the blade, push the push button in the
direction of the arrow and pull out the blade. (Fig. 6)
Adjusting the shoe (Fig. 7)
When the blade loses its cutting efficiency in one
place along its cutting edge, reposition the shoe to
utilize a sharp, unused portion of its cutting edge. This
will help to lengthen the life of the blade. To reposition
the shoe, loosen the lever and slide the shoe forward
or back to the desired position. Then tighten the lever
to firmly secure the shoe.

Switch action (Fig. 8)
CAUTION:
Before inserting the battery cartridge into the
machine, always check to see that the switch trigger
actuates properly and returns to the ''OFF'' position
when released.
To prevent the trigger from being accidentally pulled,
a lock-off button is provided. To start the machine,
press in the lock-off button and pull the trigger. The
lock-off button can be pressed in from either left or
right side of the machine. Machine speed is increased
by increasing pressure on the trigger. Release the
trigger to stop.
Operation (Fig. 9)
Press the shoe firmly against the workpiece. Do not
allow the machine to bounce. Bring the blade into light
contact with the workpiece. First, make a pilot groove,
using a slower speed. Then use a faster speed to
continue cutting.
CAUTION:
• Always use a suitable coolant (cutting oil) when
cutting metal. Failure to do so will cause premature
blade wear.
• Always wear gloves to protect your hands from hot
flying chips when cutting metal.
• Always press the shoe firmly against the workpiece
during operation. If the shoe is held away from the
workpiece during operation, strong vibration and/or
twisting will be produced, causing the blade to snap
dangerously.
