3.  With heavy leather gloves on, tug on 

the bit and make sure it is securely 

attached.  Check that it is straight.

Note:  Always use sharp bits.  Dull or 

damaged bits may cause undue stress 

on the drill and  possibly break causing 

injury.  Bits are available at Harbor 

Freight Tools.

4.  Securely clamp your workpiece.
5.  Locate the Side Handle on the desired 

side of the tool.

6.  When drilling wood, place the bit 

at the point to be drilled.  If you are 

drilling a hard, smooth surface, use a 

punch to mark the drill location.  Set 

the Directional Switch forward.  Grasp 

the handles firmly with both hands 

and slowly squeeze the 

Trigger (34).  

Never operate the tool without the side 

handle.  Never force the tool.  Only 

apply light pressure when horizontal 

drilling. If you need more or less 

torque, use the torque adjustment on 

the top of the drill.

Note:  When drilling plastics or plastic 

coated chip board, follow the same 

directions as stated in number 5 for 

wood.

Note:  If a bit becomes wedged into the 

workpiece, stop and change the 

Directional Switch to the reverse 

position.  Then slowly squeeze the 

Trigger to back the bit out of the work 

piece.

7.  When drilling metal, always use a 

punch to mark the drilling position.  

Use a lubricant to prolong the life of 

the bit and increase the drilling action 

with most metals. With steel, tin, and 

sheet metal use a light machine oil, 

with aluminum, use paraffin.  Do not 

use lubricants with brass, copper, and 

cast iron.  Grasp the handles firmly with 

both hands and slowly squeeze the 

Trigger (34).  Never operate the tool 

without the side handle.  Never force 

the tool.  Only apply light pressure 

when horizontal drilling. 

8.  When driving screws, use bits suitable 

for the type and size of screw you are 

using.  Drill a pilot hole for the screw 

head to bite into.  Use the lowest 

torque setting.  Grasp the handles 

firmly with both hands and slowly 

squeeze the 

Trigger (34).  Never force 

the tool.  To back out a screw, stop and 

change the Directional Switch to the 

back position.

1.  Unplug the drill while performing 

maintenance.

2.  Periodically check the mounting screws 

and tighten if necessary.

3.  Clean the unit with a damp cloth.  

Never use solvents to clean the unit.

4.  Inspect the chuck and remove any dirt 

or debris.

5.  Inspect the 

Carbon Brushes (29). See 

Figure 1 on page 4.

• Remove the 

(30) on top of the drill.

• Take the 

Carbon Brush (29) out of 

the 

Brush Holder (28).  If it is dirty, 

use a pencil eraser to clean it. If it 

is worn, replace it and replace the 

Carbon Brush Cap (30).  If you 

replace one Carbon Brush, you 

must replace them both.  Repeat 

the process with the 

Cap (30) on the bottom of the drill.
