Check the following after reassembly:
(1) Operate the Switch
[39]
and check that the switch moves smoothly and the switch operations (ON,
OFF, forward and reverse) are normal.
(2) Press the Switch
[39]
in “R” direction and slowly release the switch. Check that the switch returns to
the original position. Then press the Switch
[39]
in “L” direction and slowly release the switch. Check
that the switch returns to the original position.
(3) Check that the rotational direction of Anvil
[9]
matches the direction of rotation made when you press
the Switch
[39]
. When the Switch
[39]
is set to the “R” position, the Anvil
[9]
must rotate clockwise as
viewed from the rear (opposite to the Anvil
[9]
.)
On completion of reassembly after repair, measure the insulation resistance and conduct the dielectric
strength test between the plug pins and the outside metallic parts such as the Anvil
[9]
.
Insulation resistance:
7 M
ȍ
or more
Dielectric strength:
2,500 V for 1 minute --------------------------------------- 110 V to 120 V
4,000 V for 1 minute --------------------------------------- 220 V to 240 V
Screw tightening torque
Checking after reassembly
Application of lubricant
