General Power Tool Safety Warnings GEA010-1

WARNING Read all safety warnings and all

instructions. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.

Save all warnings and instructions for future reference.

RECIPRO SAW SAFETY WARNINGS

GEB008-6

1. Hold power tool by insulated gripping surfaces, when performing an operation where the cutting accessory may contact hidden wiring or its own cord. Cutting accessory contacting a "live" wire may make exposed metal parts of the power tool "live" and could give the operator an electric shock.
2. Use clamps or another practical way to secure and support the workpiece to a stable platform. Holding

the work by hand or against your body leaves it unstable and may lead to loss of control.

1. Always use safety glasses or goggles. Ordinary eye or sun glasses are NOT safety glasses.
2. Avoid cutting nails. Inspect workpiece for any nails and remove them before operation.
3. Do not cut oversize workpiece.
4. Check for the proper clearance beyond the workpiece before cutting so that the blade will not strike the floor, workbench, etc.
5. Hold the tool firmly.
6. Make sure the blade is not contacting the workpiece before the switch is turned on.
7. Keep hands away from moving parts.
8. Do not leave the tool running. Operate the tool only when hand-held.
9. Always switch off and wait for the blade to come to a complete stop before removing the blade from the workpiece.
10. Do not touch the blade or the workpiece immediately after operation; they may be extremely hot and could burn your skin.
11. Do not operate the tool at no-load unnecessarily.
12. Always use the correct dust mask/respirator for the material and application you are working with.
13. Some material contains chemicals which may be toxic. Take caution to prevent dust inhalation and skin contact. Follow material supplier safety data.

WARNING:

DO NOT let comfort or familiarity with product (gained from repeated use) replace strict adherence to safety

rules for the subject product. MISUSE or failure to follow the safety rules stated in this instruction manual may cause serious personal injury.

FUNCTIONAL DESCRIPTION

CAUTION:

• Always be sure that the tool is switched off and unplugged before adjusting or checking function on the tool.

Adjusting the shoe (Fig. 1 & 2)

When the blade loses its cutting efficiency in one place along its cutting edge, reposition the shoe to utilize a sharp, unused portion of its cutting edge. This will help to lengthen the life of the blade. To reposition the shoe, push the shoe button in the "A" direction with a click and reposition as shown in the figure which allows you to make five-way adjustment. To secure the shoe, push the shoe button in the "B" direction with a click.

Switch action

CAUTION:

• Before plugging in the tool, always check to see that the switch trigger actuates properly and returns to the "OFF" position when released.
• Switch can be locked in "ON" position for ease of operator comfort during extended use. Apply caution when locking tool in "ON" position and maintain firm grasp on tool. (Fig. 3)

To start the tool, simply pull the switch trigger. Tool speed is increased by increasing pressure on the switch trigger. Release the switch trigger to stop.

For continuous operation, pull the switch trigger, push in the lock button and then release the switch trigger.

To stop the tool from the locked position, pull the switch trigger fully, then release it.

ASSEMBLY

CAUTION:

• Always be sure that the tool is switched off and unplugged before carrying out any work on the tool.

Installing or removing the saw blade for Model MT450T

CAUTION:

• Always clean out all chips or foreign matter adhering to the blade, blade clamp and/or slider. Failure to do so may cause insufficient tightening of the blade, resulting in a serious injury. (Fig. 4)

To install the saw blade, always make sure that the blade clamp lever is in released position on the insulation cover before inserting the saw blade. If the blade clamp lever is in fixed position, rotate the blade clamp lever in the direction of the arrow so that it can be locked at the released position

CAUTION:

• If you do not insert the saw blade deep enough, the saw blade may be ejected unexpectedly during operation. This can be extremely dangerous.

• Keep hands and fingers away from the lever during the switching operation. Failure to do so may cause personal injuries. (Fig. 5)

Insert the saw blade into the blade clamp as far as it will go. The blade clamp lever rotates and the saw blade is fixed. Make sure that the saw blade cannot be extracted even though you try to pull it out. (Fig. 6)

To remove the saw blade, rotate the blade clamp lever in the direction of the arrow fully. The saw blade is removed and the blade clamp lever is fixed at the released position

NOTE:

• If you remove the saw blade without rotating the blade clamp lever fully, the lever may not be locked in the released position. In this case, rotate the blade clamp lever fully again, then make sure that the blade clamp lever locked at the released position.
• If the lever is positioned inside the tool, switch on the tool just a second to let the blade clamp out. Switch off and unplug the tool from the mains before working on the blade clamp lever.

Installing or removing the saw blade for Model MT450

CAUTION:

• Always clean out all chips or foreign matter adhering to the blade, blade clamp and/or slider. Failure to do so may cause insufficient tightening of the blade, resulting in a serious injury. (Fig. 7)

To install the blade, loosen the screw on the blade clamp with the hex wrench. Insert the blade between the blade clamp and the slider so that the pin on the slider fits into the hole in the blade shank. If the pin cannot easily fit into the hole, remove the hex wrench from the screw and then try again.

CAUTION:

• If you tighten the screw without the pin on the slider fitting properly in the hole in the blade shank, the pin or the blade shank will be damaged. This may cause the blade to be extracted unexpectedly during operation. (Fig. 8)

After the pin fits properly into the hole, tighten the screw clockwise securely. Make sure that the blade cannot be extracted even though you try to pull it out.

To remove the blade, follow the installation procedure in reverse.

Hex wrench storage (Fig. 9)

When not in use, store the hex wrench as shown in the figure to keep it from being lost.

OPERATION

CAUTION:

• Always hold the tool firmly with one hand on insulation cover and the other on the switch handle.

• Always press the shoe firmly against the workpiece during operation. If the shoe is removed or held away from the workpiece during operation, strong vibration and/or twisting will be produced, causing the blade to snap dangerously.

• Always wear gloves to protect your hands from hot flying chips when cutting metal.

• Be sure to always wear suitable eye protection which conforms with current national standards.
• Always use a suitable coolant (cutting oil) when cutting metal. Failure to do so will cause premature blade wear. (Fig. 10)

Press the shoe firmly against the workpiece. Do not allow the tool to bounce. Bring the blade into light contact with the workpiece. First, make a pilot groove using a slower speed. Then use a faster speed to continue cutting.

MAINTENANCE

CAUTION:

• Always be sure that the tool is switched off and unplugged before attempting to perform inspection or maintenance.
• Never use gasoline, benzine, thinner, alcohol or the like. Discoloration, deformation or cracks may result.

Replacing carbon brushes (Fig. 11)

Remove and check the carbon brushes regularly. Replace when they wear down to the limit mark. Keep the carbon brushes clean and free to slip in the holders. Both carbon brushes should be replaced at the same time. Use only identical carbon brushes.

Use a screwdriver to remove the brush holder caps. Take out the worn carbon brushes, insert the new ones and secure the brush holder caps. (Fig. 12)

To maintain product SAFETY and RELIABILITY, repairs, any other maintenance or adjustment should be performed by Makita Authorized Service Centers, always using Makita replacement parts.
