(5) Pull the back of the saw blade two or three times
by hand and check that the blade is securely
mounted. When pulling the blade, you will know
it is properly mounted if it clicks and the lever
moves slightly. (Fig. 6)
CAUTION
When pulling the saw blade, be absolutely sure to
pull it from the back. Pulling other parts of the blade
will result in an injury.
6. Dismounting the blade
(1) Turn on and off the switching trigger several times
so that the lever can jump out of the front cover
completely. Thereafter, turn off the switch and
unplug the power cord. (Fig. 1)
CAUTION
Be absolutely sure to keep the switch turned off
and the power cord unplugged to prevent any
accident.
(2) After you have pushed the lever in the direction
of the arrow mark shown in Fig. 2, turn the blade
so it faces downward. The blade should fall out by
itself. If the blade doesn’t fall out, pull it out by
hand.
CAUTION
Never touch the saw blade immediately after use.
The metal is hot and can easily burn your skin.
WHEN THE BLADE IS BROKEN
Even when the saw blade is broken and remains
inside the small slit of the plunger, it should fall
out if you push the lever in the direction of the
arrow mark, and face the blade downward. If it
doesn’t fall out itself, take it out using the procedures
explained below.
(1) If a part of the broken saw blade is sticking out
of the small slit of the plunger, pull out the protruding
part and take the blade out.
(2) If the broken saw blade is hidden inside the small
slit, hook the broken blade using a tip of another
saw blade and take it out. (Fig. 7)
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.
(2) As shown in Fig. 8, carry out lubrication around the
blade holder on a periodic basis by use of cutting
fluid, etc.
NOTE
Continued use of the tool without cleaning and
lubricating the area where the saw blade is installed
can result in some slack movement of the lever due
to accumulated sawdust and chips. Under the
circumstances, pull a rubber cap provided on the
lever in the direction of an arrow mark as shown
in Fig. 9 and remove the rubber cap from the lever.
Then, clean up the inside of the blade holder with
air and the like and carry out sufficient lubrication.
The rubber cap can be fitted on if it is pressed firmly
onto the lever. At this time, make certain that there
exists no clearance between the blade holder and
the rubber cap, and furthermore ensure that the
saw-blade-installed area can function smoothly.
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. 10)
7. Adjusting the base
(1) Lift the front cover up as illustrated in Fig. 11.
(2) If a base setting screw is loosened with an attached
hexagonal bar wrench, you can adjust a base
installing position. (Fig. 12, Fig. 13)
(3) After adjusting the base installing position, tighten
the base setting screw with the attached hexagonal
bar wrench completely.
8. Adjusting the blade reciprocating speed
This unit has a built-in electronic control circuit that
makes it possible to adjust the variable speed of
the saw blade by pulling a switching trigger. (Fig.
14)
If you pull the trigger further in, the speed of the
blade accelerates. Begin cutting at a low speed to
ensure the accuracy of your target cut position.
Once you’ve obtained a sufficient cutting depth,
increase the cutting speed.
CAUTION
Although this unit employs a powerful motor,
prolonged use at a low speed will increase the load
unduly and may lead to overheating. Properly adjust
the saw blade to allow steady, smooth cutting
operation, avoiding any unreasonable use such as
sudden stops during cutting operation.
HOW TO USE
CAUTION
䡬 Avoid carrying it plugged to the outlet with your
finger on the switch. A sudden startup can result
in an unexpected injury.
䡬 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.
䡬 Do not remove the front cover (refer to Fig. 1).
Be sure to hold the body from the top of the front
cover.
䡬 During use, press the base against the material
while cutting.
Vibration can damage the saw blade if the base is
not pressed firmly against the workpiece.
Furthermore, a tip of the saw blade can sometimes
contact the inner wall of the pipe, damaging the
saw blade.
䡬 Select a saw blade of the most appropriate length.
Ideally, the length protruding from the base of the
saw blade after subtracting the stroke quantity should
be larger than the material (see Fig. 15 and
Fig. 17).
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. 16, Fig. 18)
1. Cutting metallic materials
CAUTION
䡬 Press the base firmly against the workpiece.
䡬 Never apply any unreasonable force to the saw
blade when cutting. Doing so can easily break the
blade.
