Using The Optional Accessories; Maintenance And Inspection - Hitachi M 12V (S) Handling Instructions Manual

English
10) J and secure straight guide. As shown in Fig. 10,
securely attach the bottom of the base to the processed
surface of the materials. Feed the router while keeping
the guide plane on the surface of the materials.
(2) Parallel Guide (Model M8V(S), M8(S)):
Use the parallel guide for chamfering and groove
cutting along the materials side. First of all, as shown
in Fig. 10, attach the two wing bolts (A) (M6 × 15) 9 and
the two lock springs F (both standard accessories) to
the screw holes on the top side of the base. Insert the
guide bar K in the hole on the base and adjust the
distance from the bit to the guide plane L . Tighten the
two wing bolts (A) (M6 × 15) 9 to secure the parallel
guide M .
As shown in Fig. 11, securely attach the bottom of the
base to the processed surface of the materials. Feed
the router while keeping the guide plane on the surface
of the materials.
(3) Template Guide:
Use the template guide when employing a template
for producing a large quantity of identically shaped
products.
As shown in Fig. 12, secure the template guide N to
the base of the router with two accessory screws. At
this time, ensure that the projection side of the template
guide N is facing the bottom surface of the base of the
router.
A template is a profiling mold made of plywood or thin
lumber. When making a template, pay particular
attention to the matters described below and illustrated
in Fig. 13.
When using the router along the interior plane of the
template P , the dimensions of the finished product
will be less than the dimensions of the template P , by
an amount equal to dimension "A", the difference
between the radius of the template guide N and the
radius of the bit O . The reverse is true when using the
router along the exterior of the template P .
Secure the template to the workpiece. Feed the router
in the manner that the template guide moves along
the template as shown in Fig. 14.
3. Adjusting the rotating speed (Model M12V(S), M8V(S)
only)
Model M12V(S) and M8V(S) have an electronic control
system that allows stepless rpm changes.
As shown in Fig. 15, dial Q position "1" is for minimun
speed and position "5" for maximum speed.
4. Cutting
(1) As shown in Fig. 16, remove the bit from the work
pieces and press the switch lever up to the ON position.
Do not start cutting operation until the bit has reached
full rotating speed.
(2) The bit rotates clockwise (arrow direction indicated on
the base). To obtain maximum cutting effectiveness,
feed the router in conformance with the feed directions
shown in Fig. 17.

USING THE OPTIONAL ACCESSORIES

1. Model M12V(S), M12SA(S)
(1) Trimmer Guide (Fig. 18 V ):
Use the trimmer guide for trimming or chamfering.
Attach the trimmer guide V to the bar holder H as
shown in Fig. 19. After aligning the roller X to the
29
appropriate position, tighten the two wing bolts (A) 9
and the other two wing bolts (C) J . Use as shown in
Fig. 20.
2. Model M8V(S), M8(S)
(1) Trimmer Guide (Fig. 21 V )
Use the trimmer guide for trimming, chamfering or
working the inner surface. Attach the trimmer guide V
to the base as shown in Fig. 22. After aligning the roller
X to the appropriate position, tighten the two wing
bolts (A) 9 and the other wing bolt (C) J . Use as
shown in Fig. 22.
(2) Feed screw ass'y (Fig. 21 W )
The feed screw assembly can be used to make fine
adjustments in the distance between the bit and the
parallel guide or trimmer guide. Attach the feed screw
I to the parallel guide M or the trimmer guide as
shown in Fig. 24 and then attach the rod Y to the base
using the nuts provided. Turn the feed screw I to
make fine adjustments. Push the button on the feed
screw I to release the grip of the screw and allow fast
movement of the guide.
3. Model M12V(S), M12SA(S), M8V(S), M8(S)
(1) Dust collector Set (Fig. 27 \ )
Connect the dust collector set (Fig. 27 \ ) cleaner to
collect dust.

MAINTENANCE AND INSPECTION

1. Adjusting the lock lever position:
The lock lever part is provided with a brass lock piece
to protect the column. When the lock piece becomes
excessively worn, the lock position of the lock lever
tends to drop. Should router operation and handling
become difficult as a result, remove the E-type retaining
ring and adjust the setting position of the dodecagonal
hole on the lock lever and the hexagonal axis of the
lock screw, as shown in Fig. 25.
2. 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.
3. Inspecting the mounting screws:
Regularly inspect all mounting screws and ensure that
they are properly tightened. Should any of the screws
be loose, retighten them immediately. Failure to do so
could result in serious hazard.
4. Inspecting the carbon brushes: (Fig. 26)
The motor employs carbon brushes which are
consumable parts. Since an excessively worn carbon
brush could sesult in motor trouble, replace a carbon
brush with a new one having the same carbon brush
No. shown in the figure when it becomes worn to or
near the "wear limit" Z in addition, always keep
carbon brushes clean and ensure that they slide freely
within the brush holders.
Replacing a carbon brush:
Disassemble the brush cap with a minus-head
screwdriver. The carbon brush can then be easily
removed.
5. Maintenance of the moter:
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.
