Milwaukee 5385-20 用户手册

NOTE: Only use accessories 
with SDS or SDS Plus shanks.
Be sure that the shank of the bit is clean. Dirt par-
ticles may cause the bit to line up improperly. Do not 
use bits larger than the maximum recommended 
capacity of the drill because gear damage or mo-
tor overloading may result. For best performance, 

Selecting Action
MILWAUKEE  Hammer-Drills have two settings: 
drilling and hammer-drilling.  
1. For drilling, turn the hammer-drill lever towards 

the drill symbol  . 

2. For hammer-drilling, turn the hammer-drill lever 

towards the hammer symbol 

.

 To engage the hammering mechanism, 

maintain pressure on the bit.  When pressure 
on the bit is released, the hammering action will 
stop.

Using Forward/Reverse Lever
The forward/reverse lever can only be adjusted 
when the trigger is not pressed. Always allow the 
motor to come to a complete stop before using the 
forward/reverse lever.
1.  For forward (clockwise) rotation, push the con-

trol switch to the left side of the tool

  

. Check 

the direction of rotation before use.

be sure that the bit is properly sharpened and the 
shank is lightly greased before use.
1. Insert the bit or chisel into the nose of the tool. 
2. Rotate bit slowly until it aligns with the locking 

mechanism.

3. Push bit into tool until it locks.
4. Check that the bit is locked properly; it should 

be possible to pull the bit back and forth slightly 
(about 1/4”).

5. To remove bits and chisels, pull bit holder release 

collar toward the rear of tool and remove bit. 
NOTE: Use caution when handling hot bits and 
chisels.

2. For reverse (counterclockwise) rotation, push 

the control switch to the right side of the tool

 

. 

Check direction of rotation before use. 

NOTE: When hammer-drilling, use the tool in for-
ward rotation (clockwise) only.

Starting, Stopping and Controlling Speed
1. To start the tool, grasp the handle fi rmly and pull 

the trigger.  

2. To  vary the speed, increase or decrease the 

pressure on the trigger. The further the trigger 
is pulled, the greater the speed. 

3. To stop the tool, release the trigger. Make sure 

the tool comes to a complete stop before laying 
the tool down.

Locking Trigger
The lock button holds the trigger in the ON position 
for continuous full speed use.
1.  To lock the trigger, hold in the lock button while 

pulling the trigger. Release the trigger.

2. To unlock the trigger, pull the trigger and release. 

The lock button will pop out.

Operating
Position the tool, grasp the handles fi rmly and pull 
the trigger. Always hold the tool securely using both 
handles to maintain control. This tool has been 
designed to achieve top performance with only 
moderate pressure. Let the tool do the work.
If the speed begins to drop off when drilling large 
or deep holes, pull the bit partially out of the hole 
while the tool is running to help clear dust. Do not 
use water to settle the dust since it will clog the bit 
fl utes and tend to make the bit bind in the hole. If 
the bit should bind, a built-in, non-adjustable slip 
clutch prevents the bit from turning. If this occurs, 
stop the tool, free the bit and begin again.

injury, always unplug your tool before 
performing any maintenance. Never disas-
semble the tool or try to do any rewiring 
on the tool’s electrical system. Contact a 
MILWAUKEE service facility for ALL repairs.

Maintaining Tools
Keep your tool in good repair by adopting a regular 
maintenance program. Before use, examine the 
general condition of your tool. Inspect guards, 
switches, tool cord set and extension cord for 
damage. Check for loose screws, misalignment, 
binding of moving parts, improper mounting, bro-
ken parts and any other condition that may affect 
its safe operation. If abnormal noise or vibration 
occurs, turn the tool off immediately and have the 
problem corrected before further use. Do not use a 
damaged tool. Tag damaged tools “DO NOT USE” 
until repaired (see “Repairs”).
Under normal conditions, relubrication is not neces-
sary until the motor brushes need to be replaced. 
After six months to one year, depending on use, 
return your tool to the nearest MILWAUKEE service 
facility for the following:
• Lubrication
•  Brush inspection and replacement
• Mechanical inspection and cleaning (gears, 

spindles, bearings, housing, etc.)

•  Electrical inspection (switch, cord, armature, etc.)
•  Testing to assure proper mechanical and electri-

cal operation

Cleaning
Clean dust and debris from vents. Keep the tool 
handles clean, dry and free of oil or grease. Use 
only mild soap and a damp cloth to clean your tool 
since certain cleaning agents and solvents are 
harmful to plastics and other insulated parts. Some 
of these include: gasoline, turpentine, lacquer thin-
ner, paint thinner, chlorinated cleaning solvents, 
ammonia and household detergents containing 
ammonia. Never use fl ammable or combustible 
solvents around tools.

Repairs
If your tool is damaged, return the entire tool to the 
nearest service center.

Drilling in Wood, Composition Materials and 
Plastic
When drilling in wood, composition materials and 
plastic, select the drill operating mode. Start the 
drill slowly, gradually increasing speed as you 
drill. Select low speeds for plastics with a low 
melting point.

Drilling in Metal
When drilling in metal, select the drill operating 
mode. Use high speed steel twist drills or hole 
saws. Use a center punch to start the hole. Lubri-
cate drill bits with cutting oil when drilling in iron 
or steel. Use a coolant when drilling in nonferrous 
metals such as copper, brass or aluminum. Back 
the material to prevent binding and distortion on 
breakthrough.

Drilling in Masonry
When drilling in masonry, select the rotary hammer 
operating mode. Use high speed carbide-tipped 
bits. Drilling soft masonry materials such as cinder 
block requires little pressure. Hard materials like 
concrete require more pressure. A smooth, even 
fl ow of dust indicates the proper drilling rate. Do 
not let the bit spin in the hole without cutting. Do 
not use water to settle dust or to cool bit. Do not 
attempt to drill through steel reinforcing rods. Both 
actions will damage the carbide.
