(Fig.AX)Insert the lower blade into the
shears. Turn the lower blade clockwise
as inserted into the shears and insert the
hole on the lower blade over the pin of the
blade arm for lower blade.
4
After inserting the upper and lower
blades over the pins of the blade arms,
pull the upper and lower blades, and con-
firm that they do not detach.
∗
If the blades detach, they are not insert-
ed over the pins of the blade arms prop-
erly. In such a case, reinsert them.
5
(Fig.AY) Insert the aluminum base be-
tween the blade and the machine and ad-
just the hole for the hex socket head bolt.
∗
If the blades are open too wide, the alu-
minum base floats and cannot be in-
stalled.
6
(Fig.AZ) Tighten the four hex socket head
bolts using the attached hex wrench.
∗
Tighten bolt "a" holding the short end
of the L-wrench, and tighten bolt "b"
holding the long end of the wrench.
(To stabilize the tightening force)
7
(Fig.BA) Apply the attached grease all
around the shaft.
8
(Fig. BB) Insert the shaft in the shaft hole.
Insert the shaft so that its flat face will be
matched with the hole of the aluminum
base.
∗
If it is difficult to insert the shaft, swing
the lower blade in both vertical and lat-
eral directions.
9
(Fig.BC) While holding the shaft to pre-
vent it from coming out, install the blade
holder by rotating it with your hand.
∗
Tighten the blade holder firmly until
you cannot rotate it any more without
using a tool.
0
(Fig.BD) Install the washer and be sure to
tighten the hex bolt using the attached
wrench.
After carrying out the above process, connect
the machine to the control box and check its op-
eration.
If the upper and lower blades are operating cor-
rectly, the replacement work is completed.
If the blades do not operate correctly, remove
and install them again according to the proce-
dure in "HOW TO REPLACE BLADES" (P 23). If
the machine still does not operate correctly, re-
turn it to your dealer for inspection or repair.
7. MAINTENANCE PROCEDURE
•
When inspecting or servicing, be sure to
turn off the switch of the control box and
disconnect the connecting cable from the
machine.
If you inspect or service the machine with the
connecting cable connected, an unexpected
accident may occur.
1
How to maintain blades
(Fig.BE) After working, remove dirt from both
sides of the blades using a hard brush and wipe
them with wet cloth for storage.
If the blades are not maintained, the friction of
the blades will increase and the usage time after
one charge is shortened.
The lives of the blades will also be shortened.
2
How to sharpen blades
(Fig.BF) How to sharpen upper blade
Match the flat side of the grindstone to the angle
of the blade edge, press it in the direction of the
arrow and sharpen the entire blade edge.
3
How to apply grease
Apply grease to the shaft at the rate of once
a month or so.
(Fig.BI) Apply the grease evenly to the shaft
and grease sump.
For information about how to remove the
shaft, see "HOW TO REPLACE BLADES",
Step 1 and 2 (P 23).
WARNING
CAUTION
•
(Fig.BG) Do not sharpen the lower
blade.
CAUTION
•
(Fig.BH) Do not sharpen the reverse
side of the blade.
