Maintenance And Inspection - Hitachi FM 8 Handling Instructions Manual

router by sliding the pilot along the side of the
material as shown in Fig. 13.
3. Cutting
(1) Turn the switch to the ON position while the bit
is separated from the material as shown in Figs.
14 and 15. Do not start cutting operation until the
bit has reached full rotating speed.
(2) The bit rotates clockwise (arrow direction indicated
on the end bracket). To obtain maximum cutting
effectiveness, feed the router in conformance with
the feed directions shown in Fig. 16.
(3) As illustrated in Fig. 17, when the router is feed
in the direction indicated by the black arrow, a
certain force acts on the routher that causes it to
move in the direction indicated by the white arrow.
During operation, be sure to guide the router so
that it does deviate from the desired cutting line.
HOW TO USE THE OPTIONAL ACCESSORIES
1. Feed screw assembly
By using the feed screw assembly, the distance
between the bit and the parallel guide assembly or
trimmer guide assembly can be finely adjusted. As
shown in Fig. 18, attach the feed screw to the
parallel guide assembly or trimmer assembly, and
attach the rod to the base with the provided nuts.
Fine adjustment can be achieved by turning the
feed screw. Pushing the button on the feed screw
will release the grip of the screw and permit fast
movement of the guide assembly.
2. Trimmer guide assembly
Suitable for trimming, beveling or working the inner
surface of furniture or house fittings with plywood
or veneer surfaces. Insert the assembly guide bars
into the holes of the base, adjust the distance
between the bit and roller as desired, and tighten
the wing bolts on the base to fix the trimmer in
position. Then, loosen the wing bolt (A), shown in
Fig. 19, and set the roller to the appropriate posi-
tion. Ensure that the wing bolt (A), is firmly retight-
ened before using the machine, as shown in Fig.
20.
3. Chuck Sleeve
When using the 6mm or 6.35 mm ø bit for a collet
with an inner diameter of 8mm, you need the 8
× 6 or 8 × 6.35 chuck sleeve, respectively.
CAUTION
8 × 6 chuck sleeve is equipped with a groove, while
the 8 × 6.35 is not. Never use a 6mm ø shaft bit
with an 8 × 6.35 chuck sleeve, or a 6.35mm ø shaft
bit with an 8 × 6 chuck sleeve.
4. Collet
Use the proper collet according to the diameter of
the bit used.

MAINTENANCE AND INSPECTION

1. Oiling
To ensure smooth vertical movement of the router,
occasionally apply a few drops of machine oil to
the sliding portions of the columns and end bracket.
2. Inspecting the mounting screws:
Regurarly inspect all mounting screws and ensure
that they are properly tightened. Should any of the
screws be loose, retighten them immediately. Fail-
ure to do so could result in serious hazard.
3. Maintenance of the motor
The motor unit winding is the very "heart" of the
power tool. Exercise due care to ensure the winding
does not become damaged and/or wet with oil or
water.
4. Servicing
Consult an authorized service agent in the event of
power tool failure.
