Battery Protection System; Angle Guide - Makita DPJ140 Instruction Manual

Battery protection system

The tool is equipped with a battery protection system. This
system automatically cuts off power to the motor 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, turn the tool off and stop the
application that caused the tool to become
overloaded. Then turn the tool on to restart.
If the tool does not start, the battery is overheated. In
this situation, let the battery cool before turning the
tool on 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.
NOTE:
The overheat protection works only with a battery
cartridge with a star mark. (Fig. 2)
Indication lamp with multi function
(Fig. 3)
Indication lamps are located in two positions.
When the battery cartridge is inserted on the tool with the
slide switch positioned in the "O (OFF)" position, the
indication lamp flickers quickly for approximately one
second. If it does not flicker so, the battery cartridge or
indication lamp has broken.
- Overload protection
- When the tool is overloaded, the indication lamp
lights up. When the load on the tool is reduced, the
lamp goes out.
- If the tool continues to be overloaded and the
indication lamp continues to light up for
approximately two seconds, the tool stops. This
prevents the motor and its related parts from being
damaged.
- In this case, to start the tool again, move the slide
switch to the "O (OFF)" position once and then to the
"I (ON)" position.
- Battery cartridge replacing signal
- When the remaining battery capacity gets small, the
indicator lamp lights up during operation earlier than
enough capacity battery use.
- Accidental re-start preventive function
- Even if the battery cartridge is inserted on the tool
with the slide switch in the "I (ON)" position, the tool
does not start. At this time, the lamp flickers slowly
and this shows that the accidental re-start
preventive function is at work.
- To start the tool, first slide the slide switch toward
the "O (OFF)" position and then slide it toward the "I
(ON)" position.
Adjusting the depth of groove (Fig. 4)
6 grooving depths can be preset according to the size of
biscuit to be used.
Refer to the table below for the correspondence between
the sizes marked on the stopper and the biscuit size. Fine
adjustments to the grooving depth can be made by turning
the adjusting screw after loosening the hex nut. This may
become necessary after the blade has been resharpened
a few times.

Angle guide

The angle guide height can be moved up and down to
adjust the position of the blade in relation to the top of the
workpiece. (Fig. 5)
To adjust the angle guide height, loosen the lock lever
down and rotate the knob until the pointer points to the
desired scale graduation marked on the angle guide.
(Fig. 6)
Then tighten the lock lever up to secure the angle guide.
The scale on the angle guide indicates the distance from
the top of the workpiece to the center of the blade
thickness.
The angle guide is removable from the fence according to
the need of your work. To remove the angle guide, loosen
the lock lever and turn the knob clockwise until it comes
out of the upper end of the fence.
Fence
NOTE:
• Remove the angle guide according to the need of your
work when using the tool with the angle of the fence
adjusted to other than 0°. When you need to use the
angle guide under the above condition, be sure to
adjust the depth of groove to get a proper depth.
(Fig. 7 & 8)
The angle of the fence can be adjusted between 0° and
90° (positive stops at 0°, 45° and 90°). To adjust the
angle, loosen the lock lever and tilt the fence until the
pointer points to the desired graduation on the angle
scale. Then tighten the lock lever to secure the fence.
When the fence is set at 90°, both the distance from the
center of the blade thickness to the fence and the
distance from the center of the blade thickness to the
bottom of the blade cover are 10 mm.
Set plate (Fig. 9 & 10)
Use the set plate as shown in the figures when cutting
slots in thin workpieces.
Switch action (Fig. 11)
CAUTION:
• Before installing the battery cartridge into the tool,
always check to see that the slide switch actuates
properly and returns to the "OFF" position when the
rear of the slide switch is depressed.
• Switch can be locked in "ON" position for ease of
operator comfort during extended use. Apply caution
when locking tool in "ON" position and maintain firm
grasp on tool.
