Maintenance And Inspection - Hitachi M 6SB Handling Instructions Manual

3. Template guide
Application:
It is handy to process with a template a number
of materials in one same shape.
(In this case 6 × 6 mm or 6.35 × 6.35 mm
(1/ 4" × 1/4") straight bit is usable.)
(1) Remove the base ass'y from the main unit.
(2) Loosen the right and left wing bolts and secure the
base horizontally.
(3) Install the template in the recessed part of the base
and secure it with two screws.
NOTE:
Tighten the two screws moderately. Optimum
tightening torque is 10-15 kg-cm.
(4) Install the base ass'y in the main unit. (Fig. 13)
CAUTION
When fit the template guide, the upper part of the
template guide must not touch the collet chuck.
(5) Securely fix the template to the workpiece. Feed the
trimmer following the template. (Fig. 13)

Template
Template is referred to also as profillig mold and
is made from a plywood or a thin wooden plate.
Be careful of the following in producing a
template:
When putting following the inner edge of the
template, the workpiece is cut smaller because
of the distance between the template guide and
bit edge (with a 6 × 6 mm straight bit: 2.0 mm
or 6.35 × 6.35 mm (1/4" × 1/4"): 1.8 mm). By
following the outer edge of the template, the
workpiece is cut larger. (Figs. 14 and 15)
The thickness of the template should be 5 mm
or more.

MAINTENANCE AND INSPECTION

1. Inspecting the bit
Continued use of a dull or damaged bit will result
in reduced cutting efficiency and may cause
overloading of the motor. Replace the bit with a
new one as soon as excessive abrasion is noted.
2. 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.
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.
