Chip Cover Positioning; Angular Cutting; Selection Of Blades - Hitachi FCJ 65V3 Handling Instructions Manual

CHIP COVER POSITIONING

1. Chip cover
Use the chip cover to reduce fl ying of cut particles and to
easily operate the saw.
Slide the chip cover while lightly pressing its front section.
The chip cover can be set at three positions as shown in
Fig. 5.
2. How to choose the position of the ship cover
Set the chip cover to the fi rst step when attaching or
removing the blade.
Set the chip cover to the second step when cutting
wooden materials.
Set the chip cover to the second or third step when
cutting metal materials such as steel.
CAUTION
○ Keep always the chip cover in the low position when
operating the tool.
○ Wear protection glasses even if the chip cover is used.
ADJUSTING THE BLADE OPERATING
SPEED .......................................... (FCJ65V3 only)
NOTE
The blade operating speed cannot be adjusted for FCJ65S3.
The blade operating speed can be adjusted within a range of
0 to 3,000/min according to the degree that the trigger switch
is depressed. Select the speed appropriate to the material
being worked and/or the working conditions.
To achieve continuous operation, pull the trigger switch all
the way back and depress the stopper. Then, turn the speed
adjustment knob to adjust the blade operating speed as
desired.
NOTE
The speed adjustment knob rotates approximately 1.5
turns. To turn the switch OFF, pull the trigger switch again to
disengage the stopper, and release the trigger switch.
CUTTING
CAUTION
○ While sawing, the base must be fi rmly in contact with the
material surface, and the blade must be held at a right
angle. If the base becomes separated from the material,
it could cause the blade to break.
○ When cutting while holding the front surface, be careful of
the moving blade and hold the upper part fi rmly.
1. Rectilinear cutting
(1) To ensure accurate rectilinear cutting, employ the
optional accessory guide as shown in Fig. 6.
(2) Use the splinter guard to reduce roughness of the cutting
surface of wooden materials. Attach the splinter guard by
inserting it from the front section of the base until it clicks
into place. (Fig. 7)
CAUTION
Set the base in the front position when using the splinter
guard.
2. Cutting a circle or a circular arc
To ensure effi cient cutting, employ the optional accessory
guide and nail or wood screw as shown in Fig. 8.
When mounting the guide, loosen the base bottom
screw, and shift the base as far forward as it will go.
3. Sawing curved lines
When sawing a small circular arc, reduce the feeding
speed of the machine. If the machine is fed too fast, it
could cause the blade to break.
4. Cutting metallic materials
Always use an appropriate cutting agent (spindle oil,
soapy water, etc.). When a liquid cutting agent is not
available, apply grease to the back surface of the material
to be cut.
5. Pocket cutting
(1) In lumber
Aligning the blade direction with the grain of the wood,
cut step by step until a window hole is cut in the center of
the lumber. (Fig. 9)
(2) In other materials
When cutting a window hole in materials other than
lumber, initially bore a hole with a drill or similar tool from
which to start cutting.

6. Angular cutting

Set the chip cover to the fi rst step. (Fig. 5)
To adjust the angle of inclination; loosen the base
bottom screw, shift the base position to the side groove
of the semicircular portion, align the scale on the base
semicircular portion (fi gures engraved on the scale
indicate the angle of inclination) with the housing edge
line, and thoroughly tighten the base bottom screw. (Fig.
10 and 11)
CAUTION
Set the screw to the opposite side of the inclining side
when using the guide. (Fig. 12)
7. Dust produced in operation
CAUTION
○ To prevent accidents, turn the switch off and remove the
plug from the power supply when not in use.
○ For instruction on using the dust collector and applicable
cutting debris, please read the dust collector instruction
manual.
The dust produced in normal operation may aff ect
the operator's health. Either of following way is
recommended.
a) Wear a dust mask
b) Use external dust collection equipment
When using the external dust collection equipment,
connect the rubber adapter (accessory of external dust
collection equipment) with end the of hose from external
dust collection equipment.
Then connect the another end of rubber adapter with the
hose attachment part that positioned in rear end of jig
saw. (See Fig. 13)

SELECTION OF BLADES

1. Accessory blades
To ensure maximum operating effi ciency and results it is
very important to select the appropriate blade best suited
to the type and thickness of the material to be cut. One
type of blade is provided as standard accessory. The
blade number is engraved in the vicinity of the mounting
portion of each blade. Select appropriate blades by
referring to Table 1.
