Milwaukee 5366-1 User manual

Installing Bits (Fig 1.)
This tool is designed with a universal drive system that
accepts SDS, SDS Plus and Hilti-TE-C style bits. Always
clean and lubricate the shank of the bit before installing it
into your tool to help prevent heat build-up and to protect the
bit shank from wear due to abrasive concrete dust.
1. To install a bit, pull
the chuck collar back
toward the tool.
2. Line up the recesses on
the shank of the bit with
the marks on the chuck
collar as shown. Then,
insert the bit into the
spindle as far as possible.
3. Release the chuck col-
lar, locking the bit into
position. Rotate the bit
slightly to be sure it is
locked securely.
4. To remove the bit, pull
the chuck collar back
toward the tool and
remove the bit.
Installing the Side Handle and the Depth Gauge
The tool is shipped with the side handle and depth rod pack-
aged separately.
1.To install the handle assembly, pry open the black handle
ring (wedging the head of a large screwdriver in the handle
ring gap may be helpful) and slip it over the nose of the gear
case, making sure that the molded keys on the inside diame-
ter of the handle ring engage the groove on the gear case.
2. Pass the bolt through the hole in the handle ring and screw
on the red side handle.
3. The depth rod passes through the auxiliary hole in the
handle ring and is clamped in place when the side handle is
tightened. To loosen the rod, partially unscrew the handle as
indicated above.
4. The drilling depth is the distance between the portion of
the bit where the flutes end and the tip of the depth rod (Fig
2.) Slide the depth rod backward or forward until it is set for
the desired depth. Then tighten the side handle securely.
Selecting Drill or Rotary Hammer Action (Fig 3.)
MILWAUKEE 3/4” Rotary Hammers have two settings: rota-
tion only or rotary hammering.
1. To select rotation only, rotate the shift knob 180° in the
direction of the double arrow so that the tab portion of the
knob points toward the “Drill” symbol. Do not shift the tool
when it is running or coasting to a stop.

When drilling in wood or steel, shift knob to Rotation Only
and use chuck adapter kit shown on page 3.
2. To select rotary hammering, rotate the shift knob 180° in
the direction of the double arrow so that the tab portion of the
knob points toward the “Hammer” symbol.
NOTE: To engage the hammering mechanism, maintain
pressure on the bit. When pressure on the bit is released, the
hammering action will stop.
Using the Forward/Reverse Switch (Fig. 4 & Fig. 5)
1. For forward (clockwise) rotation, hold the tool with the
nose pointing away from you and push the forward/reverse
switch to the left. For the pistol grip hammer, hold the tool
with the nose pointing away from you and push the
forward/reverse switch to the left.
2. For reverse (counterclockwise) rotation, hold the tool with
the nose pointing away from you and push the
forward/reverse switch to the right. To prevent damage to the
gears and motor, allow the tool to coast to a full stop before
reversing. For the pistol grip hammer, hold the tool with the
nose pointing away from you and push the forward/reverse
switch to the right. To prevent damage to the gears and
motor, allow the tool to coast to a full stop before reversing.
Starting, Stopping & Controlling Speed
1. To start the tool, pull the trigger.
2. To vary driving speed, simply increase or decrease pres-
sure on the trigger. The further the trigger is pulled, the
greater the speed.
3. To stop the tool, release the trigger.
Rotary Hammering (Fig 6.)
Position the tool, grasp the
handles firmly and pull the
trigger. Always use the side
handle. Hold the tool secure-
ly and maintain control. Use
only enough pressure to hold
the tool in place and to pre-
vent the tip of the bit from
wandering. This tool has
been designed to achieve top
performance with only mod-
erate pressure. Heavier pres-
sure will not significantly
increase the drilling rate and
it may overload the motor
and cause premature bit
wear.
If the speed begins to drop off when drilling 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 flutes and tend to make the bit bind in the

hole. If the bit should bind, a built-in, nonadjustable slip
clutch prevents the bit from turning (a ratcheting sound will
be audible). If this occurs, stop the tool, free the bit by
switching the motor to reverse, and begin again.
Using Rotary Percussion Core Bits (Fig 7.)
Core bits are useful for drilling large holes for conduit and
pipe. MILWAUKEE Heavy-Duty Thin Wall Core Bits have
heat treated steel bodies with durable carbide tips. They are
specially designed for fast, accurate drilling with combined
hammering and rotary action.
1. Clean and lubricate the threads on the adapter and core bit
as shown to make later removal easier. Screw the threaded
end of the adapter into the rear of the core bit.
2. Push the guide plate onto the pointed end of the center pin.
Insert the center pin and guide plate assembly into the core
bit. Be sure the small end of the center pin is securely placed
into the hole in the center of the core bit.
3. Insert the adapter into the nose of the tool as described on
page 1.Set the rotary hammer/drill lever to rotary hammer.
4. Press the center pin firmly against your center mark, hold
the tool firmly and pull the trigger.
NOTE: Center pins and guide pins are not required for 1”
and 1-1/8” core bits. To make starting these bits easier, use a
template or notched board as shown.
5. After drilling to about the depth of the core bit teeth,
remove the center pin and guide plate from the core bit. Then
resume drilling.
6. After you have finished drilling the hole, hold the tool
upwards, pointing it away from your body as shown, and run
it briefly in forward to loosen the core bit from the adapter.
MILWAUKEE Heavy-Duty Thin Wall Core Bits drill holes up
to 3” deep. To make deeper holes, remove the bit, break and
remove the core. Then resume drilling.
