Maintenance and care
1.
Inspect blades (C) before installation. Check for sharpness.
Dull blades increase the risk of blade kickback reac-
tions.Small cracks can develop into fractures resulting in a
piece of blade flying off during operation. Discard cracked
blades no matter how small the crack.
2.
Securely tighten the blade retainer (B), blade, lower blade
retainer (D), cup (E), and nut (F) by hand.
3.
Insert locking tool (G) into a hole located on the right side of
angle transmission while forcing retainer spring to the left
side.
4.
Insert locking tool further into blade retainer fixing slot (A) to
fix output shaft.
5.
Tighten the nut (turn anticlockwise) using a socket wrench
(H). Never fasten while applying your weight. Otherwise the
thread of nut could be broken.
Checking the blade
Use only blade designated for this model by the manufacturer.
When a crack is noticed on the blade, do not use it but replace
with a new one.
Ensure that the blade is correctly fitted in accordance with the
instructions.
When the cutting blade becomes dull due to wear reverse it for
further use.
When chip or bend occurs on the blade, vibration will increase.
Replace with new one.
When filing the blade file 3 cutting edges evenly using a flat file
as shown in the illustration. Otherwise, the balance will be lost
and vibration will increase.
CAUTION
Fix output shaft securely using locking tool in order to
prevent it form rotating when blade is mounted. Other-
wise, the blade fastening nut will not be tightened suffi-
ciently.
