2. How to bore (Fig. 20)
(1) Connect the plug to the receptacle.
(2) A spring is installed in the center pin. Push it lightly
to the wall or the fl oor straight. Connect all over the
surface of the core bit tip and start operating.
(3) When boring about 3/16" (5 mm) in depth the position
of the hole will establish. Bore after that removing the
center pin and the guide plate from core bit.
(4) Application of excessive force will not only expedite
the work, but will deteriorate the tip edge of the drill
bit, resulting in reduced service life of the rotary
hammer.

MAINTENANCE AND INSPECTION

WARNING:
Be sure to switch power OFF and disconnect the plug from the receptacle during maintenance and inspection.
1. Inspecting the drill bits
Since use of a dull tool will cause motor malfunctioning
and degraded efficiency, replace the drill bit with a
new one or resharpening without delay when abrasion
is noted.
2. Inspecting the screws
Regularly inspect all screws and ensure that they are
properly tightened. Should any of the screws be loose,
retighten them immediately.
WARNING:
Using this Rotary Hammer with loosen screws is
extremely dangerous.
3. Maintenance of the motor
The motor unit is the very "heart" of the power tool.
Exercise due care to ensure the motor does not
become damaged and/or wet with oil or water.
4. Grease replacement
This Rotary Hammer is full air-tight construction to
protect against dust and to prevent lubricant leakage.
Therefore, this Rotary Hammer can be used without
lubrication for long periods. Replace the grease as
described below.
Grease Replacement Period
After purchase, replace grease after every 6 months
of usage. Ask for grease replacement at the nearest
authorized Service Center.

and strike the head of the core bit shank strongly two
or three times with a manual hammer holding the
core bit, then the thread becomes loose and the core
bit can be removed.
