Low-battery Capacity Indicator
If the LED worklight begins to rapidly and continuously flash when the switch on the
tool is depressed, the battery-pack power has run out, and the battery pack should be
recharged.
Unlike other battery pack types, Lithium-Ion battery packs deliver fade-free power for
their entire run time. The tool will not experience a slow, gradual loss of power as you
work. To signal that the battery pack is at the end of its run time and needs to be
charged, the power to the tool will drop quickly.
NOTE:
The LED may also flash due to an overload or high temperature (see Battery
Protection).
Battery Protection
The battery circuitry protects the battery pack from extreme temperature, over
discharge, and over-charge. To protect the battery from damage and prolong its life,
the battery pack circuitry will turn off the battery pack if it becomes overloaded or if the
temperature becomes too high during use. This may happen in situations involving
extremely high torque, binding and stalling. This intelligent system will shut down your
battery pack if its operating temperature exceeds 176°F (80°C) and will begin normal
operation when it returns to 32°F (0°C) – 122°F (50°C).
The LED worklight light will begin to flash slowly if the battery circuitry detects a
momentary overload.
NOTE:
The battery can automatically reset. If the LED continues to flash rapidly, it is
indicating that the charge is substantially diminished. Place the battery into the charger
for charging. (See BATTERY CAPACITY INDICATOR, above.)
NOTE:
A significantly reduced run time after fully charging the battery pack indicates
that the battery is near the end of its usable life and must be replaced.
Variable Speed Dial
To operate the tool, select the speed
setting you wish with the speed dial,
shown in
figure 10
, and slide the
ON/OFF switch forward. The speed
setting can be adjusted either with the
tool on or off.
CAUTION:
Because the
PCL120MT has a separate speed dial for
setting the speed (7,500 -15,000 OPM),
the tool will start at the speed where the
speed dial is set. Be sure switch is fully
OFF before inserting the battery into the tool.
The numbered positions,1 through 6 inscribed on the variable speed dial, do not
indicate any precise speed but are good reference points. The higher the number, the
higher the tool speed.
The approximate speed at each setting is:
SPEED SETTING
1
2
3
4
5
6
APPROXIMATE SPEED 7,500
9,000
10,500 12,000 13,500 15,000
(Actual OPMʼs on your tool may vary.)
Be sure to select the proper speed for your oscillating tool operation. If in doubt about
the proper speed for your operation, test the performance at low speed settings and
gradually increase until a comfortable speed is found.
