THROWING AWAY THE CUTTING DUST
CAUTION:
䡬
To prevent possible accidents, always turn the metal
cutter off and unplug before attempting to empty
out the cutting dust.
䡬
Cutting dust from metal materials may be very hot.
Do not touch the cutting dust or dust covers (A)
or (B) with bare hands.
䡬
Be careful when handling dust covers (A) and (B)
as not to bend them. If they become bent, cutting
dust may spill out.
1. Throwing away the cutting dust
If too much cutting dust accumulates inside dust
covers (A) and (B), the performance of dust collector
may decrease. Be sure to empty out the cutting dust
before the dust receptacle becomes full.
(1) Screw off the dust wing bolts by turning them to
the counterclockwise. (See Fig. 11).
(2) Use the handle to remove dust cover (B) and throw
out the cutting dust (See Fig. 12).
(3) Remove any cutting dust that has adhered to dust
covers (A) and (B) and wipe them with a rag, etc..
Then, replace dust cover (B) and fasten with the
wing bolt.
MAINTENANCE AND INSPECTION
1. Inspecting the carbide tipped saw blade
Since use of a dull saw blade will cause motor
malfunctioning and degraded efficiently, replace with
a new one without delay when 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.
4. Inspecting the carbon brushes (Fig. 13)
The motor employs carbon brushes which are
consumable parts. Since an excessively worn carbon
brush can result in motor trouble, replace the carbon
brushes with new ones having the same carbon
brush No. shown in the figure when they become
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 caps with a slotted-head
screwdriver. The carbon brushes can then be easily
removed.
