Tips for maintaining maximum battery life
1. Charge the battery cartridge before completely
discharged.
Always stop tool operation and charge the bat-
tery cartridge when you notice less tool power.
2. Never recharge a fully charged battery cartridge.
Overcharging shortens the battery service life.
3. Charge the battery cartridge with room tempera-
ture at 10°C – 40°C (50°F – 104°F). Let a hot bat-
tery cartridge cool down before charging it.
4. Charge the battery cartridge once in every six
months if you do not use it for a long period of
time.
FUNCTIONAL DESCRIPTION
CAUTION:
• Always be sure that the tool is switched off and the bat-
tery cartridge is removed before adjusting or checking
function on the tool.
Installing or removing battery cartridge (Fig. 1)
• Always switch off the tool before installing or removing
of the battery cartridge.
• To remove the battery cartridge, slide it from the tool
while sliding the button on the front of the cartridge.
• To install the battery cartridge, align the tongue on the
battery cartridge with the groove in the housing and slip
it into place. Always insert it all the way until it locks in
place with a little click. If you can see the red indicator
on the upper side of the button, it is not locked com-
pletely. Install it fully until the red indicator cannot be
seen. If not, it may accidentally fall out of the tool, caus-
ing injury to you or someone around you.
• Do not use force when installing the battery cartridge. If
the cartridge does not slide in easily, it is not being
inserted correctly.
Battery protection system (Lithium-ion battery
with star marking) (Fig. 2)
Lithium-ion batteries with a star marking are equipped
with a protection system. 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 trigger switch on the tool
and stop the application that caused the tool to
become overloaded. Then pull the trigger switch
again to restart.
If the tool does not start, the battery is overheated.
In this situation, let the battery cool before pulling the
trigger switch 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.
Switch action (Fig. 3)
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.
• When not operating the tool, depress the trigger-lock
button from B side to lock the switch trigger in the
“OFF” position.
To prevent the switch trigger from accidentally pulled, the
trigger-lock button is provided.
To start the tool, depress the trigger-lock button from A
side and pull the switch trigger.
Release the switch trigger to stop. After use, always
press in the trigger-lock button from B side.
ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and the bat-
tery cartridge is removed before adjusting or checking
function on the tool.
Replacement of blades
CAUTION:
• Never remove the blades with bare hands. Wear
gloves. Otherwise it can cause injury.
Removing cutting head (Fig. 4)
Use the hex wrench to loosen the three screws which
secure the cutting head. Pull the cutting head straight out
to remove it with turning it left and right alternately.
Removing shear blades (Fig. 5)
Remove the three screws which hold the cutting head.
When removing the second screw, be careful not to fall
the sleeve. Then the blades can be removed easily.
When removing the blades, hold the blades and the
sleeve so that they do not fall from the cutting head.
Installing shear blades (Fig. 6)
Install the sleeve and tighten the three screws after
inserting the center blade, side blade L & R into the cut-
ting head. In this process, the screw heads should be
protruding 2 – 3 mm from the cutting head surface.
If you will tighten the screws excessively, the cutting head
cannot be installed to the tool.
Installing cutting head (Fig. 7)
CAUTION:
• Secure the cutting head firmly. Otherwise it can rotate
during operation and can cause serious injury.
Insert the cutting head into the tool with turning it left and
right alternately. Then tighten the three screws with the
hex wrench.
Hex wrench storage (Fig. 8)
When not in use, store the hex wrench as shown in the
figure to keep it from being lost.
Carry hook (Fig. 9)
The carry hook is convenient for temporarily hooking the
tool. It can be installed on either side of the tool.
When removing the carry hook, widen it by pressing its
right ends ON BOTH SIDES in the directions of arrow (1)
and raise it in the direction of the arrow (2).
OPERATION
CAUTION:
• Edges and chips of the workpiece are sharp. Wear
gloves. Otherwise it can cause injury.
Secure the workpiece firmly. Move the tool forward keep-
ing the side blades flush with the workpiece surface.
