Drill Maintenance:

Drill due to ventilation, dust inside the long-term use very much, lubricants dust make gears and bearings (sleeve) on a dry mix deterioration increased wear, particularly the use of alternative even more. To guarantee the accuracy of the rotation of the drill, because reducing bearing (sleeve) and excessive wear of the gap, it is highly desirable to keep the interior clean and greasing lubrication.

method:

1)Loosen the outer drill a few nails or self-tapping screw; wherein the flat half shell opened; general hand drill new structure is a semi-recessed, that all mechanical and electrical components are means in the other half shell;

 

2)Carefully remove the first brush, then won the drill chuck side, then gently lift the motor rotor removed (not bruised enameled), wipe clean the commutator (in contact with the carbon brush that is) on the rotor, if dirty or badly worn first with sandpaper or emery cloth polished with water metallographic sandpaper to light.

 

3)Front rotors, rear bearing if it is sealed to the outside can be wiped clean, if the seal is broken should be promptly replaced. The helical axis of the rotor before wiped clean.

 

4)The casing of the oil clean wipe clean. The drill chuck rod helical gears and bearings at both ends (or sleeve) clear wiped clean.

 

5)Replace the removed stuff, first with the rotor; refill drill chuck helical gear lever; loaded brush, brushes if less than 7-8 mm should be promptly renewed.Brush installed to flatten, the last may seek out the grease is applied between the gears and bearings (or sleeve) to all parts installed flatten check to cover the other half is correct, tighten the screws, turned by hand feel no jamming, it can turn power on again.

 

 

Removing the hand drill is prohibited under power! No electrical basics are never hands!

Drill operation safety rules:

1.Personal protection when using power drill

 

1)When the face-up job, you want to wear a protective mask. On the cast iron drilling to wear protective glasses to protect the eyes.

 

2)Bit holder should be properly installed

 

3)When the job is in the drill burning state, it should pay attention to skin burns.

 

4)Handheld drill drill Φ12mm above should be drilled using a pistol with a side handle drilling.

 

5)Standing on a ladder or work should be prepared to work at heights falls measures ladder should be ground personnel support.
