MAINTENANCE AND INSPECTION OF SAW BLADE
MOUNT
(1) After use, blow away sawdust, earth, sand, moisture,
etc., with air or brush them away with a brush, etc., to
ensure that the blade mount can function smoothly.
NOTE
Continued use of the tool without cleaning the
area where the saw blade is attached can result in
sawdust and chip buildup which may adversely aff ect
the movement of the lever. Should this be the case,
pivot the lever and clean around the plunger and
lever by wiping or blowing away the buildup.
CAUTION
Do not use any saw blade with a worn-out blade
hole. Otherwise, the saw blade can come off,
resulting in personal injury. (Fig. 9)

4. Adjusting the base
To maximize blade life, the base slides in or out
to allow the stroke length to be adjusted for better
effi ciency.
(1) Turn off the switch and remove the battery.
(2) Pivot the base lever clockwise; and slide the base to
the desired position. There are fi ve positions that the
base can be adjusted to.
(3) Pivot the base lever counterclockwise to secure the
base. (Fig. 10)

(4) Make sure that the base is not interfering with the

WARNING
To avoid injury and damage, do not operate the
saw without the base in place. The plunger may
strike against the workpiece and damage the
reciprocating mechanism.
5. Check battery insertion
WARNING
If the battery is inserted while the power switch
is in the ON position, the power tool will start
operating immediately, inviting serious accident.
CAUTION
Until the battery locks in place with a little click,
if not, it may accidentally fall out of the tool
causing injury to you or someone around you.

OPERATION

WARNING
Never touch the moving parts.
CAUTION
Be careful not to let sawdust, earth, moisture,
etc., enter the inside of the machine through
the plunger section during operation. If sawdust
and the like accumulate in the plunger section,
always clean it before use.
Do not remove the front cover (refer to Fig. 1).
Be sure to hold the body from the top of the
front cover.
During use, press the base against the material
while cutting.
Vibration can damage the saw blade if the base
is not pressed fi rmly against the workpiece.
Furthermore, a tip of the saw blade can sometimes
contact the inner wall of the pipe, damaging the
saw blade.
Select a saw blade of the most appropriate
length. Ideally, the length protruding from the
base of the saw blade after subtracting the
stroke should be larger than the material (see
Fig. 11 and Fig. 13).
If you cut a large pipe, large block of wood, etc.,
that exceeds the cutting capacity of a blade;
there is a risk that the blade may contact with
the inner wall of the pipe, wood, etc., resulting in
damage. (Fig. 12, Fig. 14)
