Installing Bits into Keyed Chucks

Be sure that the shank of the bit and the chuck jaws are clean. Dirt particles 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 motor overloading may result. For best performance, be sure that the bits are properly sharpened before use.

EXTENSION CORDS

Grounded tools require a three wire extension cord. Double insulated tools can use either a two or three wire extension cord. As the distance from the supply outlet increases, you must use a heavier

voltage, resulting in loss of power and possible tool damage. Refer to the table shown to determine the required minimum wire size.

The smaller the gauge number of the wire, the greater the capacity of the cord. For example, a 14 gauge cord can carry a higher current than a 16 gauge cord. When using more than one extension cord to make up the total length, be sure each cord contains at least the minimum wire size required. If you are using one extension cord for more than one tool, add the nameplate amperes and use the sum to determine the required minimum wire size.

Guidelines for Using Extension Cords

•If you are using an extension cord outdoors, be sure it is marked with the suffix “W-A” (“W” in Canada) to indicate that it is acceptable for outdoor use.

•Be sure your extension cord is properly wired and in good electrical condition. Always replace a damaged extension cord or have it repaired by a qualified person before using it.

•Protect your extension cords from sharp objects, excessive heat and damp or wet areas.

ASSEMBLY

WARNING To reduce the risk of injury, always unplug tool before attaching or removing accessories or making adjust-

ments. Use only specifically recommended accessories. Others may be hazardous.

WARNING To reduce the risk of injury, always use a side handle when using

this tool. Always brace or hold securely.

Adjusting the Side Handle Position

1.Loosen the side handle by unscrewing the side handle grip until the side handle rotates freely.

2.Rotate the side handle to the desired position.

3.Tighten the side handle grip securely.

Setting the Depth Gauge

1.Press in the clamping lever.

2.Slide the depth gauge rod backward or forward until it is set for the desired depth.

NOTE: The drilling depth is the distance between the tip of the bit and the tip of the rod.

3.Release the clamping lever.

WARNING To reduce the risk of injury do not grasp the bit while the chuck is rotat- ing or while the bit is falling from the chuck.

WARNING To prevent personal injury, always remove the chuck key from the

chuck after each use.

WARNING To reduce the risk of injury, always unplug tool before attaching or remov- ing accessories or making adjustments. Use only specifically recommended accessories. Others may be hazardous.

WARNING To reduce the risk of injury, wear safety goggles or glasses with side shields.

WARNING To reduce the risk of injury, keep hands and cord away from the bit and all moving parts.

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 .

NOTE: 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 for-	Forward
	ward/reverse lever to the
	left (when viewed from
	the back of the tool) as
	shown.	Reverse
2.	For reverse (counter-
	clockwise) rotation, push

the forward/reverse lever to the right (when viewed from the back of the tool) as shown. Allow the motor to come to a full stop before reversing.

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

Starting, Stopping & Controlling Speed

1.To start the tool, pull trigger.

2.To stop the tool, release trigger.

3.To vary the speed, increase or decrease pres- sure to trigger. The further the trigger is pulled, the greater the speed.

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 firmly and pull the trigger. Always hold the tool securely using both handles and 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 deep holes, pull the bit partially out of the hole while the tool is running to help clear dust. Do not use wa- ter 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, non-adjustable slip clutch activates. If this occurs, stop the tool, free the bit and begin again.

Operator Force

This hammer-drill features the Vibration Isolation System to provide the operator with comfort without sacrificing power or performance. The motor hous- ing is suspended independently from the switch handle. Insulating elements absorb vibration when hammer-drilling and drilling.

Ideal operator force compresses the handle slightly and allows the tool to work aggressively while the handle provides maximum vibration dampening.

Excessive operator force compresses the handle too far and reduces the vibration dampening. Users will be able to feel the difference and should adjust the force to the handle accordingly.
