• Due to our continuing program of research and development, the specifications herein are subject to change without notice.
• Specifications may differ from country to country.
• The weight may differ depending on the attachment(s). The lightest and heaviest combination, according to EPTA-Procedure 01/2014, are shown in the table.

Intended use

The tool is intended for flush trimming and profiling of wood, plastic and similar materials.

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 and can, therefore, also be used from sockets without earth wire.

Noise

The typical A-weighted noise level determined according to EN62841-2-17: Sound pressure level (L_pA): 85 dB(A)

Sound power level (L_WA): 93 dB (A)

Uncertainty (K): 3 dB(A)

NOTE: The declared noise emission value(s) has been measured in accordance with a standard test method and may be used for comparing one tool with another. NOTE: The declared noise emission value(s) may also be used in a preliminary assessment of exposure.

Wear ear protection. The noise emission during actual use of the power tool can differ from the declared value(s) depending on the ways in which the tool is used especially what kind of workpiece is processed. Be sure to identify safety measures to protect the operator that are based on an estimation of exposure in the actual conditions of use (taking account of all parts of the operating cycle such as the times when the tool is switched off and when it is running idle in addition to the trigger time).

Vibration

The vibration total value (tri-axial vector sum) determined according to EN62841-2-17: Work mode: rotation without load

Vibration emission (a_h): 2.5 m/s² or less

Uncertainty (K): 1.5 m/s²

The vibration emission during actual use of the power tool can differ from the declared value(s) depending on the ways in which the tool is used especially what kind of workpiece is processed. Be sure to identify safety measures to protect the operator that are based on an estimation of exposure in the actual conditions of use (taking account of all parts of the operating cycle such as the times when the tool is switched off and when it is running idle in addition to the trigger time).

SAFETY WARNINGS

General power tool safety warnings

Read all safety warnings, instructions, illustrations and specifications provided with this power tool. Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury.

Save all warnings and instructions for future reference.

The term "power tool" in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

Trimmer safety warnings

1. Hold the power tool by insulated gripping surfaces only, because the cutter may contact its own cord. Cutting 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 your hand or against the body leaves it unstable and may lead to loss of control.
3. The trimmer bit shank must match the designed collet chuck.
4. Only use a trimmer bit that is rated at least equal to the maximum speed marked on the tool.
5. Wear hearing protection during extended period of operation.
6. Handle the trimmer bits very carefully.
7. Check the trimmer bit carefully for cracks or damage before operation. Replace cracked or damaged bit immediately.
8. Avoid cutting nails. Inspect for and remove all nails from the workpiece before operation.
9. Hold the tool firmly.
10. Keep hands away from rotating parts.
11. Make sure the trimmer bit is not contacting the workpiece before the switch is turned on.
12. Before using the tool on an actual workpiece, let it run for a while. Watch for vibration or wobbling that could indicate improperly installed bit.
13. Be careful of the trimmer bit rotating direction and the feed direction.
14. Do not leave the tool running. Operate the tool only when hand-held.
15. Always switch off and wait for the trimmer bit to come to a complete stop before removing the tool from workpiece.
16. Do not touch the trimmer bit immediately after operation; it may be extremely hot and could burn your skin.
17. Do not smear the base carelessly with thinner, gasoline, oil or the like. They may cause cracks in the base.
18. Some material contains chemicals which may be toxic. Take caution to prevent dust inhalation and skin contact. Follow material supplier safety data.
19. Always use the correct dust mask/respirator for the material and application you are working with.
20. Place the tool on stable area. Otherwise falling accident may occur and cause an injury.

SAVE THESE INSTRUCTIONS.

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

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

Adjusting trimmer bit protrusion

To adjust the bit protrusion, open the locking lever and move the base up or down as desired by turning the adjusting screw. After adjusting, close the locking lever firmly to secure the base.

Switch action

Before plugging in the tool, always be sure that the tool is switched off.

To start the tool, press the I side of the switch. To stop the tool, press the O side of the switch.

► Fig.2:

1. Switch

Electronic function

The tool is equipped with the electronic functions for easy operation.

Indication lamp
► Fig.3:

1. Indication lamp

The indication lamp lights up green when the tool is plugged. If the indication lamp does not light up, the mains cord or the controller may be defective. The indication lamp is lit but the tool does not start even if the tool is switched on, the carbon brushes may be worn out, or the controller, the motor or the ON/OFF switch may be defective.

Unintentional restart proof
The tool does not start with the I side of the switch pressed even when the tool is plugged. At this time, the indication lamp blinks in red and shows the unintentional restart proof device is on function. To cancel the unintentional restart proof, press the O side of the switch.

Soft start feature
Soft-start feature minimizes start-up shock, and makes the tool start smoothly.

Constant speed control
Electronic speed control for obtaining constant speed. Possible to get fine finish, because the rotating speed is kept constant even under the loaded condition.

Speed adjusting dial

Do not use the speed adjusting dial during operation. The trimmer bit can be touched by the operator because of reaction force. This may result in personal injury.

If the tool is operated continuously at low speeds for a long time, the motor will get overloaded, resulting in tool malfunction. The speed adjusting dial can be turned only as far as 6 and back to 1. Do not force it past 6 or 1, or the speed adjusting function may no longer work.

The tool speed can be changed by turning the speed adjusting dial to a given number setting from 1 to 6.

► Fig.4:

1. Speed adjusting dial

Higher speed is obtained when the speed adjusting dial is turned in the direction of number 6. And lower speed is obtained when it is turned in the direction of number 1.

This allows the ideal speed to be selected for optimum material processing, i.e. the speed can be correctly adjusted to suit the material and bit diameter. Refer to the table for the relationship between the number settings on the dial and the approximate tool speed.

Number	min-1
1	10,000
2	12,000
3	17,000
4	22,000
5	27,000
6	34,000

ASSEMBLY

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

Installing or removing trimmer bit

Do not tighten the collet nut without inserting a trimmer bit, or the collet cone will break. Use only the wrenches provided with the tool.

There are two ways to install the trimmer bit. Perform either way.

With two wrenches
Insert the trimmer bit all the way into the collet cone and tighten the collet nut securely with one wrench while holding the neck with the other wrench.

2. Bit revolving direction
3. Workpiece
4. Straight guide

Since excessive cutting may cause overload of the motor or difficulty in controlling the tool, the depth of cut should not be more than 3 mm at a pass when cutting grooves. When you wish to cut grooves more than 3 mm deep, make several passes with progressively deeper bit settings.

Base (resin)

Optional accessory

You can use the base (resin) as an optional accessory as shown in the figure.
