EXTENSION CORDS

TOOL ASSEMBLY

Grounded tools require a three wire exten- sion 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 gauge extension cord. Using extension cords with inadequately sized wire causes a serious drop in 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 ex- ample, 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 out- doors, 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 prop- erly 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.

WARNING

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

Removing and Replacing Quik-Lok®Cords (Cat. No. 6523-21)

MILWAUKEE's exclusive Quik-Lok®Cords provide instant field replacement or sub- stitution.

Fig. 1

1.To remove the Quik-Lok® Cord, turn the cord nut 1/4 turn to the left and pull it out.

2.To replace the Quik-Lok® Cord, align the connector keyways and push the connector in as far as it will go. Turn the cord nut 1/4 turn to the right to lock.

Selecting a Blade

Use MILWAUKEE Sawzall® Blades for best performance. When selecting a blade, choose the right type and length.

Blade

Unplug the tool before changing blades. Be sure the spindle and blade clamp areas are clean. Metal chips and sawdust may prevent the Quik-Lok® Blade Clamp from clamping securely.

1.	Depending on the job, the blade may
	be inserted with the teeth facing up or
	down. To install a blade, twist collar in
	the direction of the arrow while inserting
	the blade into the clamp until the tang
	butts against the collar.
2.	Release collar and the spring loaded
	mechanism will clamp the blade firmly
	in place.
3.	Twist collar in the opposite direction of
	the arrow to ensure that the blade is
	locked into the clamp.
4.	Tug on blade to make sure it is securely
	locked in place.
5.	To remove a blade, twist collar in the

READ AND SAVE ALL INSTRUCTIONS FOR FUTURE USE.

Many types of blades are available for a variety of applications: cutting metal, wood, nail-embedded wood, scroll cutting, rough- ing-in, and contours.

Many lengths are also available. Choose a length long enough to extend beyond the shoe and your work throughout the stroke.

Do not use blades less than 3-1/2" long since they won't extend beyond the shoe throughout the stroke.

For best performance and longest life, see “Accessories” to select the best blade for the job.
