Speed Change - Makita BUH550 Bedienungsanleitung

Switch action
CAUTION:
• Before inserting the battery cartridge into the
tool, always check to see that the switch trigger
actuates properly and returns to the "OFF"
position when released.
► Fig.3: 1. Switch trigger B 2. Switch trigger A
For your safety, this tool is equipped with a dual switch-
ing system. To turn on the tool, press triggers A and B.
Release either one of the two pressed triggers to turn
off. The sequence of switching is unimportant as the
tool only starts when both switches are activated.

Speed change

► Fig.4: 1. Adjusting dial
The strokes per minute can be adjusted just by turning the
adjusting dial. This can be done even while the tool is run-
ning. The dial is marked 1 (lowest speed) to 6 (full speed).
Refer to the table below for the relationship between the num-
ber settings on the adjusting dial and the strokes per minute.

CAUTION:
• The speed adjusting dial can be turned only as far
as 6 and back to 1. Do not force it past 6 or 1, or
the speed adjusting function may no longer work.
• The strokes per minute vary by the conditions of
battery cartridge and shear blades.
Battery protection system
Lithium-ion batteries are equipped with a protection sys-
tem. This system automatically cuts off power to the tool
to extend battery life.
The tool will automatically stop during operation if the
tool and/or battery are placed under one of the following
conditions:
• Overloaded:
The tool is operated in a manner that causes
it to draw an abnormally high current.
In this situation, release the switch trigger on
the tool and stop the application that caused
the tool to become overloaded. Then pull the
switch trigger again to restart.
If the tool does not start, the battery is over-
heated. In this situation, let the battery cool
before pulling the switch trigger again.
• Low battery voltage:
The remaining battery capacity is too low
and the tool will not operate. In this situation,
remove and recharge the battery.
Battery remaining capacity indicator
(only for models with Battery
BL3622A)
Battery BL3622A is equipped with the battery remaining
capacity indicator.
► Fig.5: 1. Indicator lamps 2. CHECK button
Press the CHECK button to indicate the battery remain-
ing capacity. The indicator lamps will then light for
approx. three seconds.

Indicator lamps
Lighted Off Blinking
E
When only the lowermost indicator lamp (next
to the "E") blinks, or when none of the indicator
lamps light, the battery capacity has run out, so
the tool does not operate. In these cases, charge
the battery or replace the empty battery with a fully
charged one.
When two or more indicator lamps do not light
even after charging is complete, the battery has
reached the end of its service life.
When the upper two and lower two indicator lamps
light alternately, the battery may have malfunc-
tioned. Contact your local Makita authorized ser-
vice center.
NOTE:
• The indicated capacity may be lower than the
actual level during use or immediately after
using the tool.
• Depending on the conditions of use and the
ambient temperature, the indication may differ
slightly from the actual capacity.
CAUTION:
• Always be sure that the tool is switched off and
the battery cartridge is removed before carrying
out any work on the tool.
