. SPECIFIC SAFETY  
RULES  
Such preventive safety measures  
reduce the risk of starting the tool  
accidentally.  
DO NOT let comfort or familiarity  
with product (gained from repeated  
use) replace strict adherence to  
cordless reciprocating saw safety  
rules.  
16)Store idle tools out of reach of chil-  
dren and other untrained persons.  
Tools are dangerous in the hands of  
untrained users.  
17)When battery pack is not in use,  
keep it away from other metal  
objects like: paper clips, coins, keys,  
nails, screws, or other small metal  
objects that can make a connection  
from one terminal to another.  
If you use this tool unsafely or incor-  
rectly, you can suffer serious per-  
sonal injury.  
1) Before each use, it is a good practice  
to always inspect this tool for physi-  
cal damage. If the tool has been dam-  
aged or does not operate properly,  
do not use. Have it serviced immedi-  
ately by a qualified seviceman.  
2) When installing the battery pack,  
make sure that it snaps in place and  
is mounted to the tool firmly. Replace  
the battery pack if it cannot be held  
in place securely.  
Shorting the battery terminals togeth-  
er may cause sparks, burns or a fire.  
18)Maintain tools with care. Keep cut-  
ting tools sharp and clean.  
Properly maintained tools with sharp  
cutting edge are less likely to bind  
and are easier to control.  
19)Check for misalignment or binding of  
moving parts, breakage of parts, and  
any other condition that may affect  
the tool’s operations. If damaged,  
have the tool serviced before using.  
Many accidents are caused by poorly  
maintained tools.  
20)Use only accessories that are recom-  
mended by the manufacturer for  
your model.  
3) Hold tool by insulated gripping sur-  
faces when performing an opera-  
tion where the cutting tool may  
contact hidden wiring.  
Contact with a "live" wire will make  
exposed metal parts of the tool “live”  
and shock the operator.  
4) Be aware that this tool is always in  
an operating condition, it does not  
have to be plugged into an electrical  
outlet.  
Accessories that may be suitable for  
one tool may create a risk of injury  
when used on another tool.  
5) Always use safety goggles or  
glasses with side shields.  
Service  
Ordinary eye or sun glasses are NOT  
safety glasses.  
21)Tool service must be performed  
only by qualified repair personnel.  
Service or maintenance performed by  
unqualified personnel may result in a  
risk of injury.  
6) Avoid cutting nails. Inspect work-  
piece for any nails and remove them  
before operation.  
7) Do not cut oversized workpiece.  
22)When servicing a tool, use only  
identical replacement parts. Follow  
instructions in the Maintenance  
section of this manual.  
8) Check for the proper clearance  
beyond the workpiece before cutting  
so that the blade will not strike the  
floor, workbench, etc.  
Use of unauthorized parts or failure  
to follow Maintenance Instructions  
may create a risk of shock or injury.  
9) Hold the tool firmly.  
10) Make sure the blade is not contact-  
ing the workpiece before the switch  
is turned on.  
11) Keep hands away from moving  
parts.  
12)Always switch off and wait for the  
blade to come to a complete stop

. ASSEMBLY  
WARNING:  
To reduce the risk of injury, always  
remove battery pack before chang-  
ing the blade.  
Blade  
Selecting a blade  
The blade clamp sleeve can be used  
with all 1/2" shank universal reciprocat-  
ing saw blade. When selecting a blade,  
choose the right type and length.  
WARNING:  
If you do not insert the saw blade deep  
enough, the saw blade may be eject-  
ed unexpectedly during operation.  
This can be extremely dangerous.  
Choose a length long enough to  
extend beyond the shoe and your  
work throughout the stroke. Do not use  
blades less than 3-9/16" (90 mm) long  
since they will not extend beyond the  
shoe throughout the stroke.  
To remove the saw blade, rotate the  
blade clamp sleeve in the direction  
of the arrow (clockwise from the front  
view) fully. The saw blade is removed  
and the blade clamp sleeve is fixed at  
the open position. Be careful when han-  
dling hot blades after use.  
Installing or removing the  
saw blade  
Blade clamp sleeve  
CAUTION:  
Always clean out all chips or foreign  
material adhering to the blade, blade  
clamp and/or slider before use.  
Failure to do so may cause insuf-  
ficient tightening of the blade, result-  
ing in a serious injury.  
NOTE:  
Depending on the job, the blade may  
be inserted with the teeth facing up or  
down. To install the saw blade, always  
make sure that the blade clamp sleeve  
is in open position before inserting the  
saw blade. If the blade clamp sleeve is  
in the close position, rotate the sleeve  
to the open position until it clicks.  
If you remove the saw blade without  
rotating the blade clamp sleeve fully,  
the sleeve may not be fixed. In this  
case, rotate the blade clamp sleeve  
fully, then make the sleeve fixed at  
the open position.  
Blade Clamp Maintenance  
Blade clamp sleeve  
Always keep blade clamp sleeve clean  
and dry after use.  
Periodically lubricate blade clamp sleeve  
with a dry lubricant. Using wet lubricant  
may keep the dust and debris, and  
causes malfunction of the blade clamp.  
Open position Close position  
Insert the saw blade into the blade  
clamp until the saw blade snaps in  
place and clamp sleeve rotates.

. OPERATION  
Hold tool by the insulated gripping  
surfaces when performing an oper-  
ation where the cutting tool may  
contact hidden wiring.  
WARNING:  
To reduce the risk of injury, keep  
hands away from the blade and  
other moving parts.  
Always wear safety goggles or  
glasses with side shields.  
Adjusting shoe  
Starting and Stopping  
When the blade loses its cutting effi-  
ciency 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 shoe lock lever counter-  
clockwise and slide the shoe forward  
or back to the desired position. Then  
tighten the lever clockwise to firmly  
secure the shoe.  
To start the tool, grasp the handle  
firmly. Press the switch lock lever,  
which can be pressed in from either  
left or right side of the tool.  
Then pull the trigger switch.  
To stop the tool, release the trigger.  
Allow the tool to come to a complete  
stop before removing the blade from a  
partial cut or before laying the tool down.  
Controlling speed by Trig-  
ger Switch  
Shoe lock lever  
The reciprocating saw is equipped  
with a trigger speed control switch.  
It may be operated at any speed  
from zero stroke per minute to full  
speed. Always start tool before blade  
contacts the workpiece. To vary the  
speed, simply increase or decrease  
the pressure on the trigger. The further  
the trigger is pulled, the greater the  
speed.  
Shoe  
Switch action  
CAUTION:  
Before inserting the battery pack into  
the tool, always check to see that the  
trigger switch actuates properly and  
returns to the “OFF” position when  
released.  
Cutting materials  
Before the blade contacts the work-  
piece, grasp the handle firmly and  
pull the trigger. Begin cutting at slow  
speed, gradually increasing speed as  
you cut. When cutting into materials  
or hard materials that can not be cut  
from an edge, drill a starting hole larg-  
er than the widest part of the blade.  
Switch lock lever  
CAUTION:  
•Always press the shoe firmly  
against the workpiece during oper-  
ation. 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.  
Trigger switch  
To prevent the trigger switch from  
being accidentally pulled, a lock-off  
button switch lock lever is provided.  
Always make sure the switch is locked  
when carrying or storing the tool to  
eliminate unintentional starting.  
Always wear gloves to protect your  
hands from flying hot chips when

cutting metal.  
Battery Pack Life  
Always use a suitable coolant (cut-  
ting oil) when cutting metal. Fail-  
ure to do so will cause premature  
blade wear.  
The rechargeable batteries have a  
limited life. If operation time becomes  
extremely short after recharging,  
replace the battery pack with a new one.  
If the tool is operated continuously  
until the battery pack has dis-  
charged, allow the tool to rest for  
15 minutes before proceeding with  
a fresh battery pack.  
NOTE:  
Use under extremely hot or cold  
conditions will reduce operating  
capacity per charge.  
Charging  
NOTE:  
When you charge the battery pack for  
the first time, or after prolonged stor-  
age, charge it for about 24 hours to  
bring the batteries up to full capacity.  
Battery charger (EY0110)  
Press the shoe firmly against the  
workpiece. Do not allow the tool to  
bounce. Bring the blade into light con-  
tact with the workpiece. First, make  
a pilot groove, using a slower speed.  
Then use a faster speed to continue  
cutting.  
1. Plug the charger into the AC outlet.  
NOTE:  
Sparks may be produced when the  
plug is inserted into the AC power  
supply, but this is not a problem in  
terms of safety.  
2. Insert the battery pack firmly into the  
charger.
