Installing And Removing Bits; How To Use The Router - Hitachi M8V2 Handling Instructions Manual

3. Extension cord
When the work area is removed from the power source,
use an extension cord of suffi cient thickness and rated
capacity. The extension cord should be kept as short as
practicable.
4. RCD
The use of a residual current device with a rated residual
current of 30 mA or less at all times is recommended.

INSTALLING AND REMOVING BITS

WARNING
Be sure to switch power OFF and disconnect the plug
from the receptacle to avoid serious trouble.
1. Installing bits
(1) Clean and insert shank of bit into the collet chuck until
shank bottoms, then back it out approximately 2 mm.
(2) With the bit inserted and pressing the lock pin holding
the armature shaft, use the 23 mm wrench to fi rmly
tighten the collet chunk in a clockwise direction (viewed
from under the router). (Fig. 1)
CAUTION
○ Ensure that the collet chuck is fi rmly tightened after
inserting a bit. Failure to do so will result in damage to
the collet chuck.
○ Ensure that the lock pin is not inserted into the armature
shaft after tightening the collet chuck. Failure to do so
will result in damage to the collet chuck, lock pin and
armature shaft.
(3) Be sure to use a chuck sleeve when using a 6 mm bit
with a collet chuck capacity of 8 mm. First insert the
chuck sleeve deeply in the collet chuck, then insert the
bit in the chuck sleeve. Tighten the collet chuck fi rmly as
in step (1) and (2).
2. Removing Bits
When removing the bits, do so by following the steps for
installing bits in reverse order. (Fig. 2)
CAUTION
Ensure that the lock pin is not inserted into the armature
shaft after tightening the collet chuck. Failure to do so
will result in damage to the collet chuck, lock pin and
armature shaft.

HOW TO USE THE ROUTER

1. Adjusting depth of cut (Fig. 3)
(1) Use stopper pole to adjust depth of cut.
1 Place the tool on a fl at wood surface.
2 Turn the stopper block so that section to which the cutting
depth setting screw on a stopper block is not attached
comes to the bottom of the stopper pole. Loosen pole
lock knob allowing the stopper pole to contact with
stopper block.
3 Loosen the lock lever and press the tool body until the bit
just touches the fl at surface. Tighten the lock lever at this
point. (Fig. 4)
4 Tighten pole lock knob. Align the depth indicator with the
"0" graduation of scale.
5 Loosen pole lock knob, and raise until indicator aligns
with the graduation representing the desired cutting
depth. Tighten pole lock knob.
6 Loosen the lock lever and press the tool body down until
the stopper block to obtain the desired cutting depth.
(2) As shown in Fig. 5 (a), loosening the two nuts on the
threaded column and moving then down will allow you to
move down to the end position of the bit when the lock
lever is loosened. This is helpful when moving the router
to align the bit with the cutting position.
As shown in Fig. 5 (b), tighten the upper and lower nuts
to secure the cutting depth.
(3) When you are not using the scale to set the cutting depth,
push up the stopper pole so that it is not in the way.
2. Stopper block (Fig. 6)
The 2 cut-depth setting screws attached to the stopper
block can be adjusted to simultaneously set 3 diff erent
cutting depth. Use a wrench to tighten the nuts so that
the cut-depth setting screws do not come loose at this
time.
3. Guiding the router
WARNING
Be sure to switch power OFF and disconnect the plug
from the receptacle to avoid serious trouble.
(1) Template Guide (Standard Accessory)
Use the template guide when employing a template
for producing a large quantity of identifi cally shaped
products.
As shown in Fig. 7, secure the template guide to the
base of the router with two accessory screws. At this
time, ensure that the projection side of the template
guide is facing the bottom surface of the base of the
router.
A template is a profi ling mold made of plywood or thin
lumber.
When making a template, pay particular attention to the
matters described bellow and illustrated in Fig. 8.
When using the router along the interior plane of the
template, the dimensions of the fi nished product will be
less than the dimensions of the template by a amount
equal to dimension "A", the diff erence between the
radius of the template guide and the radius of the bit. The
reverse is true when using the router along the exterior of
the template.
Secure the template to the workpiece. Feed the router
in the manner that the template guide moves along the
template as shown in Fig. 9.
(2) Straight guide (Standard accessory) (Fig. 10)
Use straight guide for chamfering and groove cutting
along the materials side.
1 Insert the guide bar into the hole in the bar holder, then
lightly tighten the 2 wing bolts (A) on top of the bar
holder.
2 Insert the guide bar into the hole in the base, then fi rmly
tighten the wing bolt (A).
3 Make minute adjustments of the dimensions between
the bit and the guide surface with the feed screw, then
fi rmly tighten the 2 wing bolts (A) on top of the bar holder
and the wing bolt (B) that secures the straight guide.
4 As shown in Fig. 11, securely attach the bottom of the
base to processed surface of the materials. Feed the
router while keeping the guide plane on the surface of
the materials.
4. Adjusting the rotation speed
The M8V2 has an electronic control system that allows
stepless rpm changes.
As shown in Fig. 12, dial position "1" is for minimum
speed, and position "6" for maximum speed.
5. Cutting
CAUTION
○ Wear eye protection when operating this tool.
○ Keep your hands, face and other body parts away from
the bits and any other rotating parts, while operating the
tool.
(1) As shown in Fig. 13, 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 eff ectiveness,
feed the router in conformance with the feed directions
shown in Fig. 14.
NOTE
If a worn bit is used to make deep grooves, a high
pitched cutting noise may be produced.
Replacing the worn bit with a new one will eliminate the
high pitched noise.
