1.Clean and grease the bit or chisel shank.
2.Insert the bit or chisel into the nose of the tool.
3.Rotate the bit or chisel slowly until it aligns with the locking mechanism.
4.Push the bit or chisel into the tool until it locks (Fig. 2).
5.Pull on the bit or chisel to verify that it is locked into place.
6.To remove, pull the bit release collar toward the rear of the tool and remove the bit or chisel.
WARNING To reduce the risk of injury, use only specifically recommended MILWAUKEE hammer chisels. Others may damage tool.
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 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 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 Cana- da) 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.
WARNING Improperly connecting the grounding wire can result in the risk of elec- tric shock. Check with a qualified electrician if you are in doubt as to whether the outlet is properly grounded. Do not modify the plug provided with the tool. Never remove the grounding prong from the plug. Do not use the tool if the cord or plug is damaged. If damaged, have it repaired by a MILWAUKEE service facility before use. If the plug will not fit the outlet, have a proper outlet installed by a qualified electrician.
Grounded Tools: Tools with Three Prong Plugs Tools marked “Grounding Required” have a three wire cord and three prong grounding plug. The plug must be connected to a properly grounded outlet (See Figure A). If the tool should electrically malfunction or break down, grounding provides a low resistance path to carry electricity away from the user, reducing the risk of electric shock.
The grounding prong in the plug is connected through the green wire inside the cord to the grounding system in the tool. The green wire in the cord must be the only wire connected to the tool's
Adjusting the Straight Side Handle
Screw the straight side handle into one of three po- sitions (top, left side, or right side). Tighten securely.
WARNING To reduce the risk of injury when hammering with rotation, always use the straight side handle when using this tool. Always brace or hold securely.
To reduce the risk of injury when hammering with or without rotation, wear safety goggles or glasses with side shields.

Installing Hammer Chisels
Always clean and grease the chisel shank before inserting the chisel into the tool. Inspect the shank to make sure it is not "mushroomed", as described in "Maintaining Hammer Chisels". Always make sure that the chisel is in good working condition before use.
•Protect your extension cords from sharp objects, excessive heat and damp or wet areas.

NOTE: To reduce the risk of damage to the bit lock, do not use round hex shank bits in the 5337-20. Only use hex shank bits in this tool.
1.Clean and grease the bit or chisel shank.
2.Pull out the bit lock and rotate it 180°.
3.Insert the bit or chisel into the nose of the tool (Fig. 1)
NOTE: When using hex (on cat. no. 5337-20) or hex/round (on cat. no. 5340-20) bits or chisels, the notch in the shank must face toward the bottom of the nosepiece of the tool.
4.Lock the bit or chisel by pulling out the bit lock and rotating it 180°.
5.Pull on the bit or chisel to verify that it is locked into place.
6.To remove, rotate the bit lock 180° and remove the bit or chisel. NOTE:Usecautionwhenhandlinghotbitsandchisels.
