5. Using hole to fix unit in place.
A hole is provided at the center of the unit to fix
and stabilize it. This hole comes in quite handy
when used in the following manner. (Fig. 14.)
For bending operation when the unit is fixed to a
work bench.
This hole will prove very convenient when the unit
is bolted to a suitable work bench. (Bolt size M10,
less than W3/8.)
MAINTENANCE AND INSPECTION
WARNING!
To prevent accidents, always be sure to turn the switch
OFF and unplug the power cord from the receptacle.
1. 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.
2. 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.
3. Inspecting the carbon brushes (Fig. 15)
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 which have 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.
4. Replacing carbon brushes. (Fig. 14, Fig. 15)
Loosen the set screws and remove the tail cover.
Remove the brush caps and carbon brushes. After
replacing the carbon brushes, do not forget to tighten
the brush caps securely and to mount the tail cover
with set screws.
