• Due to our continuing programme of research and

development, the specifications herein are subject to

change without notice.

• Note: Specifications may differ from country to country.

Power supply

The tool should be connected only to a power supply of

the same voltage as indicated on the nameplate, and can

only be operated on single-phase AC supply. They are

double-insulated in accordance with European Standard

and can, therefore, also be used from sockets without

earth wire.

Safety hints

For your own safety, please refer to the enclosed Safety

instructions.

ADDITIONAL SAFETY RULES

1. Wear a hard hat (safety helmet), safety glasses

and/or face shield. It is also highly recom-

mended that you wear a dust mask, ear protec-

tors and thickly padded gloves.

2. Check the blade carefully for cracks or damage

before operation. Replace cracked or damaged

blade immediately.

3. Do not attempt to cut workpieces larger than

specified in this manual (especially hollow pipe).

The blade might snap and cause an injury. (Fig. 1)

4. Hold the tool firmly.

5. Be sure no one is below when using the tool in

high locations.

6. Do not point the tool at anyone in the immediate

vicinity.

7. When making a “blind” cut (you can’t see behind

what is being cut), be sure that hidden electrical

wiring or water pipes are not in the path of the

cut. If wires are present, they must be discon-

nected at their power source by a qualified per-

son or avoided to prevent the possibility of lethal

shock or fire. Always hold the tool ONLY by the

insulated gripping surfaces to prevent any elec-

tric shock if you accidentally cut through a “live”

wire. Water pipes in “blind” areas must be

drained and capped before cutting.

8. Be careful not to hit the end of the blade against

something during operation. Damage to the tool

or dangerous blade breakage may occur. (Fig. 2)

9. Watch out for cut-off portions of the workpiece

being cut. They may fall and injure you or some-

one near you.

10. When cutting metals, be cautious of hot flying

chips.

11. Do not touch the blade or the workpiece immedi-

ately after operation; they may be extremely hot

and could burn your skin.

12. If you withdraw the blade from the workpiece

during operation, strong reaction will be pro-

duced, causing the blade to snap or causing you

to lose your grip and control of the tool. Always

switch off the tool and wait until the blade has

come to a complete stop before withdrawing the

blade from the workpiece.

SAVE THESE INSTRUCTIONS.

OPERATING INSTRUCTIONS

Important:

Always be sure that the tool is switched off and

unplugged before installing or removing the saw blade, or

adjusting the shoe.

Installing or removing saw blade (Fig. 3 & 4)

To install the blade, loosen the bolt with the hex wrench 4.

Insert the blade between the leaf spring and the slider so

that the pin on the slider fits into the hole in the blade

shank. Tighten the bolt securely while making sure that the

blade cannot be extracted even though you try to pull it out.

CAUTION:

If you tighten the bolt 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 ejected unexpectedly during operation. This can be

extremely dangerous.

To remove the blade, follow the installation procedures in

reverse.

Adjusting the shoe (Fig. 5)

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,

loosen the lever and slide the shoe forward or back to the

desired position. Then tighten the lever to firmly secure

the shoe.

Changing the cutting action (Fig. 6)

This tool can be operated in an orbital or a straight line

action. See the following chart to help determine the

proper and most efficient applications. To change the cut-

ting action, press the stopper and turn the lever to the

desired cutting action position. Then, release the stopper

to lock the lever.
