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. Check the Screws
Loose screws are dangerous. Regularly inspect
them and make sure they are tight.
CAUTION:
Using this power tool with loosened, screws is
extremely dangerous.
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. 20)
The motor employs carbon brushes which are
consumable parts. Since and excessively worn
carbon brush can result in motor trouble, replace
the carbon brush with new ones 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.
