ACCESSORIES

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.

Selecting Speed

Rotate the speed selector dial to the desired maxi- mum speed (1 through 6). Select "1" for a maximum speed of 500 strokes per minute. Select "6" for a maximum speed of 3000 strokes per minute.

Use lower speeds for materials such as plastics and laminates. Also, use lower speeds for hard metals. Use higher speeds for materials such as wood and soft metals (aluminum, copper, brass, etc.).

Starting and stopping the tool

1.To start the tool, grasp the handle firmly and pull the trigger.

2.To vary the speed, increase or decrease pres- sure on the trigger. The further the trigger is pulled, the greater the speed, up to the maximum set by the speed selector dial.

3.To stop the tool, release the trigger. Allow the tool to come to a complete stop before removing the blade from a partial cut or laying the tool down.

WARNING To reduce the risk of injury, always ensure that the trigger lock-on is in the "off" position before plugging in tool.

Trigger Lock-On

The trigger lock-on button holds the trigger in the ON position for continuous use.

1.To lock-on the trigger, pull the trigger and press in the lock-on button. Release the trigger.

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

WARNING To reduce the risk of injury, do not start the tool with the blade contacting the workpiece.

Making the Cut

1.Set the orbital action according the material to be cut.

2.Position the tool with the front part of the shoe on the workpiece and start the tool.

3.Hold the shoe firmly against the workpiece and guide the tool along the desired cutting line. Do not feed into the work too hard, light pressure on the saw blade will achieve the optimum cutting speed.

Special Cutting Techniques

1.Straight cuts — To obtain a perfectly straight cut, clamp a strip of wood as a guide along the workpiece or use the rip guide (accessory).

2.Bevel cuts — adjust the shoe to the correct angle (see Adjusting the Shoe).

3.Cutting Sheet Metal — sheet metal may vibrate when being cut. To minimize vibration, clamp the workpiece to a wood base.

WARNING To reduce the risk of explo- sion, electric shock and property damage, always check the work area for hidden gas pipes, electrical wires or water pipes when making blind or plunge cuts.

Plunge Cutting

Plunge cuts can be made into soft materials without a pre-drilled hole. Harder materials require a starter hole with a diameter slightly over the width of the blade. To make a plunge cut:

1. Set the orbital action

selector lever to 0. 2. Make sure nothing be-

low the intended cut area will be damaged.

3. Without turning the tool on, place the front edge of the shoe sol- idly on workpiece.

4. Align the blade with the intended cut line,

but keep it above the workpiece.

5.Using the front edge of the shoe as a pivot, turn on the tool and gradu- ally lower the blade into the workpiece.

6.When the shoe is flat against the workpiece, normal cutting may take place.

WARNING To reduce the risk of 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 gen- eral 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, broken 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 electrical operation

WARNING To reduce the risk of injury, electric shock and damage to the tool, never immerse your tool in liquid or allow a liquid to flow inside the tool.

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 flammable or combustible solvents around tools.

Repairs

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

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