BLADE REPLACEMENT
The hand shear uses disposable blades. Each blade has 8
cutting edges, as shown in Fig. 5. After a cutting edge cuts
400 meters of panel, cutting performance will fall. Then use
another cutting edge. After all 8 cutting edges are used and
worn, replace the blade.
MAINTENANCE AND INSPECTION
1. Inspecting the blade
Using a worn or chipped blade will put an excessive
burden on the motor and aff ect work performance.
Therefore, always use a well-cutting blade.
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.
4. Inspecting the carbon brushes (Fig. 6)
The motor employs carbon brushes which are
consumable parts. Since an excessively worn carbon
brush can result in motor trouble, replace the carbon
brush with a new one having the same carbon brush
No. shown in the fi gure when it becomes worn to or
near the "wear limit". In addition, always keep carbon
brushes clean and ensure that they slide freely within
the brush holders.
5. Replacing carbon brushes
Disassemble the brush cap with a screwdriver. The
carbon brush can then be easily removed.

WARNING
○ The vibration emission value during actual use of the
power tool can diff er from the declared value depending
on the ways in which the tool is used.
○ To identify the safety measures to protect the operator
that are based on an estimation of exposure in the
actual conditions of use (taking account of all parts of
the operating cycle such as the times when the tool is
switched off and when it is running idle in addition to the
trigger time).
